Looking around the room for a week, we can find a large number of PVC products, from the water cup on the table to the clock in the corner. The relatively low cost, wide use, and inherent durability make PVC a building material widely used in the construction field.
In any case, the impact of PVC materials on the door and window industry is undeniable. In terms of energy conservation alone, the U.S. Department of energy survey shows that if you use energy star certified PVC doors and windows instead of ordinary single-layer doors and windows, you will save about $125 to $349 in energy expenditure. Durability is also an important reason for the popularity of PVC building materials. As we all know, the longer the service life of doors and windows, the less energy consumption for the production and installation of alternative doors and windows.
As early as the 1980s, PVC has been introduced to the market. Since then, PVC products have been constantly updated, so that it has evolved into a safer, cleaner and environmentally friendly building material. At present, the improvement of PVC continues, so as to ensure that its second-generation products can realize effective recycling.
European PVC manufacturers jointly issued an initiative on PVC in 2000, hoping to continuously improve the production technology and product waste recycling process of PVC products and promote the research and development of new technologies through their own efforts. Although the initiative is not a legal obligation, it has received a response from most European enterprises. One of the objectives of the initiative is to recycle 200000 tons of PVC products every year. Through the joint efforts of European building materials enterprises, the total amount of PVC actually recovered each year is 60000 tons more than the expected target, of which 100000 tons of PVC comes from doors and windows and related industries. Since 2010, European PVC enterprises have once again formulated a 10-year plan called "vinyl plus", which aims to consolidate the achievements in PVC technology development and recycling in the past 10 years, increase the total amount of PVC product recycling to 800000 tons every year, and achieve the goal of recycling 100000 tons of extremely difficult to recycle PVC.
In the United States, similar PVC recycling projects are also carried out step by step. The public and building materials manufacturers have gradually realized their responsibility for the environment. At present, manufacturers are recycling as many PVC by-products as possible and exploring technologies that can produce PVC doors and windows with more environmental protection characteristics, so as to ensure the balance between production activities and environmental protection. From past experience, the research and development of post-industrialized recyclable PVC products did not sacrifice the beauty of the products. Thanks to the persistent pursuit of European PVC manufacturers in the past 10 years, the development of PVC has changed with each passing day.
The key to this process is to fully consider the recyclable components in PVC, so as to eliminate any impurities. Specifically, it is to determine the chemical and product compatibility of recyclable PVC products through experimental analysis. Chemical detection includes the analysis of the content of lead, calcium, titanium, tin, and other elements. Once it is proved that the recycled raw materials meet the specific chemical and physical characteristics, the Recycled PVC raw materials will be processed again, and then backlog and formed into invisible PVC films attached to the door and window structure. The visible parts of the door and window structure will use the leading generation PVC products as the film, So as to ensure the rainproof and fire resistance of doors and windows.
The use of second-generation recyclable PVC products is the future development trend. According to the report of the vinyl Association, recyclable PVC products have been officially incorporated into the public publication of building materials and the plastics industry. Manufacturers and consumers of PVC products are responsible for using recyclable PVC products as much as possible and constantly developing a new generation of more environmentally friendly PVC products.
