What is the standard for PVC materials and what is the national standard for PVC?

Hello PVC, the full name is polyvinylchlorid, the main ingredient is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface ** is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is the back-coated adhesive. It is a kind of synthetic material that is loved, popular and widely used in the world today.

It has the second highest global use of all synthetic materials. According to statistics, in 1995 alone, the production of PVC in Europe was about 5 million tons, while its consumption was 5.3 million tons. In Germany, PVC is produced and consumed on average at 1.4 million tons.

PVC is being produced and used worldwide at a growth rate of 4%. In recent years, the growth of PVC in Southeast Asia has been particularly significant, thanks to the urgent need for infrastructure development in Southeast Asian countries. Among the materials that can produce 3D tables**, PVC is the most suitable material.

PVC can be divided into soft PVC and hard PVC. Among them, hard PVC accounts for about 2 3 of the market, and soft PVC accounts for 1 3. Soft PVC is generally used on floors, ceilings and leather surfaces, but its use is limited because soft PVC contains softener (which is also the difference between soft PVC and hard PVC), which is easy to become brittle and difficult to preserve.

Hard PVC does not contain softeners, so it is flexible, easy to form, not easy to brittle, non-toxic and pollution-free, and has a long storage time, so it has great development and application value. The essence of the following abbreviation is a vacuum blister film, which is used for the surface packaging of various panels, so it is also known as decorative film and adhesive film, which is used in many industries such as building materials, packaging, and medicine. Among them, the building materials industry accounts for the largest proportion, 60%, followed by the packaging industry, and a number of other small application industries.

There are shops in Gaoqiao that are generally engaged in professional repair, thank you, I wish you all the best.

1. Polyvinyl chloride is a polymer material that uses a chlorine atom to replace a hydrogen atom in polyethylene, and is an amorphous polymer containing a small amount of crystalline structure. The structure of this material is as follows: [CH2 CHCL] is a linear polymer with a head-tail structure in which VCM monomers are mostly linked.

The carbon atoms are arranged in a zigzag pattern, and all the atoms are connected by bonds. All carbon atoms are sp3 hybridized. 2、

PVC is polyvinyl chloride, English abbreviation PVC (polyvinylchloride), is vinylchloridemonomer (VCM) in peroxide, azo compounds and other initiators; or polymers polymerized under the action of light and heat according to the reaction mechanism of free radical polymerization.

PVC pipe (PVC-U pipe) Rigid PVC pipe is extruded by hot pressing method after combining polyvinyl chloride resin with stabilizer and lubricant, and is the earliest plastic pipe to be developed and applied.

PVC-U pipe has strong corrosion resistance, easy bonding, low **, and hard texture, but due to the seepage of PVC-U monomer and additives, it is only suitable for water supply systems with a conveying temperature of no more than 45. Plastic pipes are used in applications for drainage, wastewater, chemicals, heating fluids and coolants, food, ultra-pure liquids, slurries, gases, compressed air and vacuum systems.
