PVC drainage pipe main uses:

PVC drainage pipe for urban and rural indoor and outdoor water supply project, rural water transformation, farmland irrigation project, brine pipeline project in the salt and chemical industry, aquaculture industry water transmission project, mine ventilation, water supply and drainage project, landscaping irrigation project. PVC drain pipes can last up to 50 years.

Current situation of PVC drainage pipe:

PVC drainage pipe is favored by the pipeline engineering field because of its light weight, corrosion resistance, small flow loss, easy installation and other characteristics. At the same time, compared with traditional metal pipe, PVC drainage pipe has less energy consumption and less environmental pollution, which is increasingly paid attention to by the government and relevant departments. According to relevant information shows, THE dosage of PVC drainage pipe in construction plastics is the biggest, the product varieties are also many, it as a new chemical building materials, has a wide range of development space in our country.

Application of PVC water pipes:
1: Application in the field of home decoration
Unlike PPR, PPR is mainly used for water supply pipes, while PVC can only be used for drainage pipes. Unless the budget is limited, Lao Jin does not recommend using PVC pipes in the home decoration field. However, for some balcony faucets (washing machines) or toilets, PVC pipes are still recommended.
The commonly used PVC water pipes for home decoration have three specifications: 20mm/25mm/32mm, and the most commonly used color is gray; In addition, electrical pipes are the most commonly used in home decoration, with the most common specifications being 16MM/20MM (which will be discussed later) and colors including red, blue, and white. In addition, the most commonly used sewage fittings in kitchens, toilets, and other areas are all made of PVC.
2: Application on Pollutant Discharge Buildings
Large diameter PVC water pipes are commonly used for sewage discharge and rainwater discharge in rural houses or villas. Most of them are white when installed outside, and the most commonly used specifications are 50mm/75mm/110mm/160mm. The commonly used accessories include straight, three-way, four-way, floor drain, S-trap, and reducer. To prevent pipeline blockage, it is recommended that you choose accessories with inspection ports when purchasing accessories, Convenient for future maintenance.

Construction specifications for outdoor drainage pipelines
1. Acceptance of materials
1) The specifications and varieties of water supply PE pipes and fittings should meet the design requirements, with uniform wall thickness, smooth and neat inside and outside, and no sand holes, cracks, flying thorns, and lumps. The pipe fittings should have a regular shape, qualified dimensions, and a factory certificate of conformity.
2) Valves, flanges, and other equipment should have quality certificates, no cracks, flexible and tight switches, regular casting, and good handwheels.
3) Pipe clamps, oil, hemp, mats, and raw tape should be carefully inspected and accepted as qualified.
2. General regulations for pipeline installation and laying
1) Pipelines shall not be laid on frozen soil.
2) The pipeline should be installed from downstream to upstream in sequence, with the socket connecting the pipeline facing the direction of water flow and the socket installed in the direction of water flow.
3) A casing should be installed for pipelines crossing highways and other loads, and there should be no interfaces inside the casing. The casing should be two sizes larger than the outer diameter of the pipeline.
4) When the installation and laying of pipelines are interrupted, wooden plugs or other covers should be used to seal the pipe openings to prevent debris from entering.
5) The pressure level of valves, fittings, etc. used in water supply pipelines should not be lower than the designed working pressure of the pipeline, and meet the pressure requirements of the water pressure test of the pipeline.
6) Before pipeline construction, it is necessary to understand the layout of other underground pipelines along the pipeline. The horizontal clear distance between adjacent pipelines should not be less than the width of the groove required for construction and maintenance, and the width required for the installation of valve wells and other ancillary structures. Drinking water pipelines should not be laid under drainage and sewage pipelines.
3. Preparation work before pipeline laying
1) Pipeline laying should be carried out after the elevation of the trench bottom and the inspection of the pipeline foundation are qualified. Before laying the pipeline, a visual inspection should be conducted on the pipes, fittings, rubber rings, valves, etc. Any problems found should not be used.
2) Prepare the equipment and ropes for lowering the pipe and conduct a safety inspection. For pipes with a diameter of more than 150mm, the prying and pressing rope method can be used to lower the pipe. Protective measures should be taken for the interface of the twisted joint connected pipeline.
3) If a pipeline support is required, the support should have been completed.
4) Before installing the pipeline, compressed air or other gases should be used to blow and clean the inside of the pipeline.

Amazing effect! The intelligent palletizing and feeding station is officially put into use
Industrial new products inject new momentum into the manufacturing industry

The intelligent palletizing and feeding station in the mixing room of Anhui ERA Third Workshop was officially put into operation. In this automation renovation project, the workshop selected industry-leading 3D industrial cameras and 3D visual robotic arm guidance system suppliers for migration technology, and jointly built an intelligent dismantling and feeding station to achieve unmanned operation throughout the mixing process. After the renovation, the average production capacity exceeded expectations by 100%, and the effect was very stunning.
Traditional manual dismantling is difficult
With the increase of production line scale, traditional manual palletizing and feeding gradually cannot meet production needs, resulting in"three difficulties"
Difficulty in improving efficiency
The weight of a bag of raw materials is about 25kg, and manual palletizing requires 2-3 people, which is heavy and inefficient.
Difficulty in recruitment and employment
The high labor intensity and safety hazards, coupled with the aging population trend, make it difficult to recruit and employ workers, which has become a challenge that workshops must face directly.
Difficulty in controlling costs
The cost of employment is constantly rising, and the cost of safety protection and training management is high. It is necessary to control costs in order to seek market advantages.
Seeking intelligent change, suspended?
The development of industrial manufacturing intelligence has become a consensus, and the emergence of industrial robots provides new choices for enterprises. However, traditional industrial robots are automated devices that lack intelligent perception and decision-making abilities. They can only perform simple and repetitive actions, and are obviously unable to perform tasks such as unpacking, breaking packages, and feeding. So, how to achieve intelligent palletizing and feeding?

3D vision makes this idea possible. The 3D camera and visual software are equipped with"eyes"and"brain"for the robotic arm. The camera takes photos, the software recognizes, and the robotic arm grasps. The"eyes+brain+hand"cooperation is smooth and harmonious. It is worth mentioning that the intelligent dismantling and feeding station only took 5 days from installation to debugging!
In just 5 days, there has been a revolutionary change in the mixing room of the third workshop. The robotic arm accurately grabs the raw materials, then puts them into the breaking machine, and then puts them into the material tank. The packaging bags are automatically recycled, and the entire process is completed in one go, full of a sense of technology.
After the surprise, another question is unsettling. Is it really okay to start production so quickly?
Project landing and production, installation!
With the landing and production of the intelligent palletizing and feeding project, the dark clouds that have enveloped everyone's hearts are gradually dissipating. Behind the 5-day installation and debugging is the supplier's excellent products and technology, as well as the rich experience accumulated in over 100 dismantling and feeding projects. It is also the result of in-depth understanding of workshop characteristics and production needs in the early stage.
The intelligent unpacking and feeding station is based on 3D vision and robot intelligent control as the core technology, adopting an intelligent control system to achieve unmanned operation of the entire unpacking process. It has the characteristics of strong unpacking processing ability, low material residue, simple operation, stable operation, and convenient maintenance, while greatly improving the cleanliness of the surrounding environment during the work process. In addition, the entire project plan is meticulously designed, from three color lights, safety protection to emergency stop buttons, striving to provide maximum labor safety protection and always putting safety production first.

This time, Anhui ERA has broken through traditional manual feeding and created an intelligent dismantling and feeding station, achieving a raw material feeding capacity of 3.5-4.5 tons per hour and a daily production capacity of 75-80 tons, exceeding the expected production capacity by more than 100% on average! In the later stage, Anhui ERA will continue to improve the intelligent dismantling and feeding station, build a digital factory, further reduce employee labor intensity, continuously improve employee happiness, balance production efficiency improvement, and continuously enhance the core competitiveness of the enterprise.
The plastic industry is facing a material revolution
A new technology for the production of biodegradable new material polylactic acid with completely independent intellectual property rights will be put into mass production at Henan Dancheng Jindan Lactic Acid Technology Co., Ltd. The emergence of this disruptive technology perfectly solves the industrial chain construction of producing lactic acid from corn, synthesizing polylactic acid from lactic acid, and then producing fully biodegradable products from polylactic acid. It can completely solve the problem of"white pollution"that troubles countries around the world, and has an important driving role in environmental protection and social development. At the same time, it can radiate and drive the rapid development of industries such as agriculture, industry, food, medicine, and new materials, It may trigger the rise of a series of independent industries.
For many years, the plastics, fibers, and medical materials used by people have been petroleum derivatives, which are non degradable and consume a huge amount. Currently, China consumes 60-70 million tons annually, and the amount used for packaging bags and plastic bags alone is about 7 million tons. The large-scale launch of plastics has brought great convenience to people, but its non degradability has also brought serious environmental pollution. At present, plastic waste siege, secondary pollution caused by plastic incineration, and soil hazards caused by agricultural plastic films have become global problems. At the same time, the non renewable nature of oil also makes it necessary to seek alternatives to petroleum based plastics.
Zhang Quanxing, an academician of the CAE Member of the technology research and development team and a professor of the School of Environment of Nanjing University, and Li Hong, a professor and doctoral supervisor of Nanjing University, believe that the bio based material PLA has the characteristics of non-toxic, non irritating, high heat resistance, good plasticity and processability, and is the most promising new material to replace petroleum based plastics. Henan Jindan Lactic Acid Technology Co., Ltd., located in Dancheng, has established an innovative strategic cooperation alliance through a strong alliance with Nanjing University and Nanjing University of Technology in terms of production, education, research, and application. The"Biomass Organic Guanidine Catalyzed All Green Process for Synthesizing Lactide and Polylactic Acid"developed by the National Center for Organic Toxic Pollution Control and Resource Utilization Engineering Technology at Nanjing University has solved the problems of high production cost and poor processability of polylactic acid materials compared to traditional plastic materials; The use of environmentally friendly organic guanidine catalysts has completely solved the problem of secondary pollution caused by the use of stannous catalysts (stannous octanoate, stannous chloride) in the production of polylactic acid. It is a world first, filling the world gap, and has an international leading level. It is known as a green revolution in the field of new materials, and has received great attention and competitive pursuit from the international industry.
Henan Jindan Lactic Acid Technology Co., Ltd. is a high-tech enterprise that uses corn as raw material and produces lactic acid, polylactic acid, and their derivatives through modern biotechnology. For many years, the company has firmly grasped technological innovation and has obtained multiple national patents in the production technology of lactic acid and its series of products, reaching the international advanced level and becoming the largest and second largest lactic acid production base in Asia. In recent years, the company has actively laid out the production of polylactic acid and the development of related industries. The industrial framework has rapidly opened up, and the value of the industrial chain has rapidly increased. It has once again entered the forefront of the international polylactic acid industry, winning huge development space and new development opportunities.
 
The plastic recycling industry must take a green development path
For a long time, the waste plastic recycling industry has been considered a small, scattered, and dirty industry, and it is also a focus of environmental inspection. However, the hard work, difficulty, and low profits of recycling waste plastics are the voices of industry workers. In fact, the general public is not very familiar with the flow, harm, and value that waste plastics can generate. In fact, the recycling and utilization industry of waste plastics is a process of turning waste into treasure, and it also provides unremitting impetus for circular economy and green development. Many unknown industry enterprises are striving forward. The report of the 19th National Congress proposes to promote green development and build a beautiful China. In the face of constant criticism in the industry, the plastic recycling industry urgently needs to transform and upgrade, and take the path of green development.
As a product of oil, the production of plastic has increased 20-fold from over 10 million tons in the 1960s to the present day, and is still on an exponential rise. It is expected to reach three times the current production by 2050, with the main production countries concentrated in China, the European Union, and the United States. Dr. Jiang Nanqing from the United Nations Environment Programme's China Representative Office pointed out that the global plastic production is nearly 8 million tons per year, most of which are incinerated, landfilled, and discharged into the ocean. Only 14% of plastic packaging and materials can truly be recycled, and the economic value of the loss is very large, about 80 billion US dollars. The entire lifecycle cycle of plastics has not established a good chain.
Du Huanzheng, President of the Plastic Recycling Branch of the China Synthetic Resin Association, stated that in the nearly 100 years since the birth of plastics, humans have produced 8 billion tons of plastic, some of which have accumulated in social life processes; The other part becomes garbage, and the garbage entering the landfill cannot be degraded for many years. The garbage entering the incineration plant may produce exhaust gas."Previously, it was said that aggressors invaded China, causing the country to break through mountains and rivers. Now, it can be said that 'the country is broken through mountains and rivers'. Although industry has developed and people have become prosperous, there is no clean water, fresh air, or safe food, and everything is just empty talk."Du Huanzheng believes that although improper disposal of waste plastics can cause harm to the environment, the waste plastic recycling industry is actually turning used waste resources back into renewable resources, Extending its service time for humanity also objectively protects the environment.
So, how can we transform the waste plastic recycling industry from being misunderstood to being respected? Green and sustainable development is the industry's best choice.
Jiang Nanqing stated that modern society needs to pay more and more attention to the life cycle and circular economy remanufacturing, and emphasizes the integration of environmental and social considerations in the production, processing, distribution, and use of raw materials. Only by forming a full life cycle supply chain can sustainable solutions be developed."Plastics have made tremendous contributions to the development of the national economy and the improvement of people's living standards since their inception. However, just like sugarcane does not have two sweet ends, plastics bring convenience to people's production and life, but also produce a large amount of non degradable waste plastics, causing pollution to the environment."Zhao Jungui, Secretary General of the China Petroleum and Chemical Industry Federation and President of the China Synthetic Resin Supply and Marketing Association, said, The petrochemical industry has entered a new era characterized by structural adjustment, transformation and upgrading, and green development. To achieve green development in the petrochemical industry, it should be the green development of the entire industry chain, especially in the field of waste plastic recycling. To change the traditional notion that the industry is dirty, messy, and poor, it is necessary to demonstrate new signs of green and transformative development to society."The current environmental protection situation is becoming increasingly severe, and some enterprises are facing problems such as production stoppage, closure, rectification, and upgrading. The report of the 19th National Congress also clearly points out that environmental protection is the most important issue, and the waste plastic industry should also prioritize environmental protection. Green development can enable enterprises to go further and better."Dr. Li Shurun from Beijing Environmental Sanitation Engineering Group Co., Ltd. said.
China solicits environmental control standards for waste plastics from various countries in the World Trade Organization
According to the Jiangsu Inspection and Quarantine Bureau, on November 15, 2017, China issued a notice to the World Trade Organization, soliciting opinions from various countries on the"Environmental Protection Control Standards for Imported Solid Waste Used as Raw Materials - Waste Plastics"(GB16487.12).
This standard applies to the import management of waste plastics in the catalog of imported solid waste that can be used as raw materials. The purpose of its formulation is to strictly restrict the import of solid waste and control environmental pollution caused by the import of waste plastics that can be used as raw materials. The standard defines waste plastic as thermoplastic waste, scraps, and defective products generated during plastic production and plastic product processing.
The standard requires that imported waste plastics cannot be mixed with radioactive waste, explosive weapons and ammunition such as discarded bombs and shells. The total weight of hazardous waste mixed in waste plastics must not exceed 0.01% of the weight of imported waste plastics, and the total weight of other inclusions mixed in waste plastics must not exceed 0.5% of the weight of imported waste plastics.
The Wuxi Inspection and Quarantine Bureau in Jiangsu Province reminds relevant enterprises to pay close attention to the latest standards for imported waste plastics. Enterprises importing waste plastics that can be used as raw materials must declare to the inspection and quarantine agency before entering the country. Only after passing the inspection and quarantine department's mandatory national standards can they be sold and used.
The inspection and quarantine department will strengthen the legal publicity of relevant import enterprises, continuously strengthen the supervision of waste materials, strengthen risk prevention and control measures, closely monitor the danger and radioactivity of waste materials entering the port, strictly control the quality and safety of imported waste materials, and maintain the safety of the port and the life and health of the people.
