What is pvc material pvc decoration materials

Whether it is home life or office supplies, products made of PVC materials are almost everywhere. So what is pvc material ? Pvc decoration materials which? Don't worry, here's a look at Xiaobian.

What is pvc material

Pvc Resin is a kind of plastic decorative material. Its chemical name is polyvinyl chloride. The polyvinyl chloride (PVC) color is slightly yellow translucent and shiny. The transparency is better than that of polyethylene and Polypropylene, and worse than that of polystyrene. It is divided into soft and rigid polyvinyl chloride, and the soft products are soft and tough, and the stickiness of the hand is higher than that of the low density polyethylene. Less than polypropylene, whitening occurs at the inflection point.

PVC is an amorphous white powder with a low degree of branching. Industrial production of PVC molecular weight is generally in the range of 50,000 to 120,000, with a large polydispersity, molecular weight increases with the decrease of Ethylene-Vinyl Acetate polymerization temperature; no fixed melting point, 80 ~ 85 °C began to soften, 130 °C became viscoelastic state , 160 ~ 180 °C began to change into a viscous flow state; has good mechanical properties, tensile strength of about 60MPa, impact strength 5 ~ 10kJ/m2; has excellent dielectric properties. However, the stability to light and heat is poor. When the temperature is over 100°C or exposed to sunlight for a long time, it will decompose to produce hydrogen chloride, and further autocatalytic decomposition will cause discoloration. The physical and mechanical properties will also rapidly decline. In practice, it must be added to the stability. Agent to improve the stability to heat and light. PVC is very hard and has poor solubility. It can only dissolve in a few solvents such as Cyclohexanone, dichloroethane and Tetrahydrofuran. It is stable to organic and inorganic acids, alkalis and salts, and its chemical stability increases with use temperature. And lower. PVC Boric Acid Flakes is dissolved in acetone-carbon disulfide or acetone-benzene mixed solvent. It is used for dry spinning or wet spinning. It is called Kleenex. It has flame-retardant, acid and alkali resistant, anti-microbial and anti-wear properties. Better warmth and elasticity.

Pvc decoration materials which

Pvc sheet:

The PVC board is a sheet made of Pvc Powder Sg5 as a raw material and has a honeycomb mesh structure in cross section. Is a vacuum plastic film, used for surface packaging of various types of panels, it is also known as decorative film, attached film, used in building materials, packaging, medicine and many other industries. Among them, the building materials industry accounted for the largest proportion of 60%, followed by the packaging industry, as well as a number of other small-scale applications. According to the degree of soft and hard can be divided into soft PVC and hard PVC. According to the production process can be divided into PVC crust foam board and PVC free foam board.

Pvc wallpaper:

The surface of PVC wallpaper is mainly made of polyvinyl chloride resin, mainly in the following three ways:

1. Ordinary type - 80g/sqm paper is used as paper base, 100g/sqm PVC resin is applied on the surface. The surface decoration method is usually a combination of printing, embossing, or printing and embossing.

2, foam type - - 100g / square meter of paper for the paper, coated with 300-400g / square meter of PVC resin. According to the size of the expansion ratio, there are low foaming and high foaming, respectively. The surface of high-foaming wallpaper is elastic and has a certain sound-absorbing effect.

3, functional type - which waterproof wallpaper is a glass fiber cloth as a substrate, can be used to decorate the bathroom, bathroom wall; fireproof wallpaper is 100-200g / square meters of asbestos paper as the substrate, and in the PVC surface material Incorporate flame retardants.

Pvc doors and windows:

Polyvinyl chloride (PVC-U) door and Rubber And Plastic window profiles are compounded and extruded by PVC, stabilizers, impact modifiers, processing aids, fillers, etc. in accordance with certain formulas. Selection of PVC and additives for products The performance has a great influence. With the rapid development of the extrusion of hard PVC-U door and window profiles and plastic doors and windows, the relevant PVC and additives industry has also made new progress.

Pvc pipe:

PVC (full name Polyvinylchlorid), the main ingredient is polyvinyl chloride, and other ingredients added to enhance its heat resistance, toughness, ductility and so on. The top layer of this surface film is lacquer, the main ingredient in the middle is polyvinyl chloride, and the lowest layer is back-coated adhesive. It is a kind of synthetic material that is popular, popular, and widely used in the world today. Its global use ranks second among various synthetic materials.

The above is about what is pvc material and pvc decoration materials which are simply introduced here, and hope to help everyone buy their own pvc decoration materials to help. For more information, please visit this website. Stay tuned.
