Home improvement time need to use PVC pin board knowledge and purchase skills

What is the PVC gusset? Some people should not understand the PVC gusset plate, but when the home improvement is needed to use. In order to make the owners more clearly PVC gusset plate, now introduce the knowledge of PVC gussets and buy skills. The so-called PVC gusset is made of polyvinyl chloride resin as the base material, adding a certain amount of anti-aging agent, modifier and other additives, by mixing, calendering, vacuum blistering and other processes made of ceiling materials, is the modern construction industry Often used in a class of building materials, such materials of the chess plate ceiling is particularly suitable for kitchen, bathroom ceiling decoration, with a light weight, moisture, heat insulation, easy to burn, do not smoke, easy to clean, , Easy to install, the advantages of low prices.

PVC formulation design knowledge

Pure polyvinyl chloride (PVC) resin belongs to a class of strong polar polymers, the intermolecular force is large, which led to the PVC softening temperature and melting temperature is high, generally need 160 ~ 210 ℃ to process. In addition, the substitution of chlorine in the PVC molecule easily leads to the dechlorination reaction of PVC resin, which causes the degradation of PVC. Therefore, PVC is very unstable, and the temperature increase will greatly promote the HCL reaction of PVC. Began to take HCL reaction, which led to the degradation of PVC. In view of the above two aspects of the defects, PVC in the processing need to add additives in order to be able to produce a variety of people meet the needs of soft, hard, transparent, good electrical insulation, foam and other products. In the selection of additives and the amount of variety, you must fully consider all aspects of factors such as physical - chemical properties, flow properties, forming performance, and ultimately establish the ideal formula. In addition, depending on the application and processing path, we also need to choose the type of resin. Different types of PVC resin and a variety of additives with the combination of ways, we often say that the PVC formula design. How specific to the specific formula design? The following will be through the selection of the raw materials to be described in a way to illustrate, hoping to benefit everyone.

Knowledge of small science: PVC pipe in the home use of the main purposes

Abstract: PVC material, PVC, polyvinyl chloride, is synthesized from acetylene gas and hydrogen chloride, and then polymerized. With high mechanical strength and good corrosion resistance. PVC material is one of the world's largest production of plastic products, cheap, widely used, by a lot of friends love, then the pvc tube has so much strength, that pvc tube is the main purpose of what? Talk about it!

What is PVC pipe? The most basic decoration knowledge must know

What is PVC pipe? Pvc tube is very common in the decoration is also widely used in a material. Many people are familiar with this kind of pipe is not familiar with the name. Next, the decoration network Leslie Xiaobian will change to talk about for everyone, the most basic decoration must know ah. PVC, the full name of Polyvinylchlorid, the main ingredient for the polyvinyl chloride, in addition to other ingredients to enhance its heat resistance, toughness, ductility and so on. The top layer of this surface film is a paint, the middle of the main component is polyvinyl chloride, the bottom is the back coating adhesive. It is the world's favorite, quite popular and also widely used in a synthetic material. Its global use in a variety of synthetic materials in the second. According to statistics, only one year in 1995, PVC production in Europe, there are about five million tons, while its consumption was 5.3 million tons. In Germany, PVC production and consumption of an average of 1.4 million tons.

Every day know a little more analysis of the characteristics and application of PVC materials

Often hear the so-called PVC material, but do you know what PVC is in the end? PVC and those advantages that those shortcomings? no idea? Let us look at the following small science PVC is actually a vinyl polymer, the material is a non-crystalline material. PVC materials in the actual use of often added stabilizers, lubricants, auxiliary processing agents, colorants, impact agents and other additives. With non-flammability, high strength, weather resistance and excellent geometric stability. PVC has a strong resistance to oxidants, reducing agents and strong acids. However, it can be strongly oxidized acid such as concentrated sulfuric acid, concentrated nitric acid corrosion and does not apply with aromatic hydrocarbons, chlorinated hydrocarbons in contact with the occasion. In addition the game term person vs computer, abbreviated as PVC, and PVC humanoid is often referred to as PVC and so on.

What is pvc material pvc decoration materials which

Whether it is home life or office supplies, PVC materials made of almost everywhere in the product. So what is pvc material? Pvc decoration materials which? Do not worry, the following with Xiaobian together to see it What is pvc material Pvc is a kind of plastic decorative material. Its chemical name is polyvinyl chloride. Polyvinyl chloride (PVC) character is slightly yellow translucent, shiny. Transparency is better than polyethylene, polypropylene, worse than polystyrene, with the amount of different additives, divided into soft, hard polyvinyl chloride, soft soft and tough, feel sticky, hard hardness is higher than low-density polyethylene, And lower than the polypropylene, in the inflection will appear whitening phenomenon.
