PVC board:

(1) Polyvinyl chloride (PVC) plastic is a polymer formed by free radical polymerization of vinyl chloride monomer. The English name is polyviny chloride, or PVC for short. 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.

(2) Hardness PVC celuka board : The quality of this product is in accordance with GB/T4454-1996. It has good chemical stability, corrosion resistance, high hardness, high strength, high strength, UV resistance (aging resistance), fire resistance and flame retardant (with self- Extinction), reliable insulation performance, smooth and smooth surface, no water absorption, no deformation, easy processing and other characteristics. This product is an excellent thermoforming material that can replace some stainless steel and other corrosion-resistant synthetic materials. It is widely used in chemical, petroleum, electroplating, water purification treatment equipment, environmental protection equipment, mining, medicine, electronics, communications and decoration industries. .

(3) PVC transparent board: a high-strength, high-transparent plastic board made of high-grade imported raw and auxiliary materials. The product colors are white, jewel blue, brown, brown and other varieties. The product has high strength, high transparency, good weather resistance, non-toxicity, hygiene, and physical properties better than plexiglass. It is widely used in equipment guards, interior decoration, drinking water tank, liquid level display, etc.

Acrylic board:

(1) "Acrylic" is a transliterated word, and English is ACRYLIC. It is a chemical material. The chemical name "PMMA" is a polyacrylate, commonly known as "specially treated plexiglass". In the application industry, acrylic raw materials generally appear in the form of particles, plates, pipes, etc. Acrylic is also known as specially treated plexiglass. It is a replacement product of plexiglass. The light box made of acrylic has good light transmission performance, pure color, rich color, beautiful and smooth, taking into account the two effects of day and night, long service life, and does not affect use, etc. Features. In addition, acrylic sheets, aluminum-plastic panels, high-end screen printing, etc. can be perfectly combined to meet the needs of businesses. Acrylic plastic is the best outdoor advertising form to improve the store level and unify the corporate image.

(2) Acrylic is transliterated from the English Acrylic, the general term for Acrylic acrylic and methacrylic chemicals. Including monomers, plates, pellets, resins and composite materials, acrylic sheets are made of methyl methacrylate monomer (MMA) polymerized, namely polymethyl methacrylate (PMMA) sheet plexiglass, "organic "Glass" is derived from the trade name "Oroglas" (a PMMA board), and is taken from "Organic Glass" (ie, plexiglass).

(3) Acrylic cast sheet: high molecular weight, excellent rigidity, strength and excellent chemical resistance. This kind of board is characterized by small batch processing, incomparable flexibility in color system and surface texture effect, and complete product specifications, suitable for various special purposes.

(4) Acrylic extruded sheet: Compared with cast sheet, extruded sheet has lower molecular weight and weaker mechanical properties. However, this feature is conducive to bending and thermoforming processing, and is conducive to rapid vacuum forming when processing large-sized plates. At the same time, the thickness tolerance of the extruded plate is smaller than that of the cast plate. Because extruded plates are mass-produced automated production, the color and specifications are inconvenient to adjust, so the variety of product specifications is subject to certain restrictions.

(5) Features:

Solvent resistance:

Polymethyl methacrylate can withstand relatively dilute inorganic acids, but concentrated inorganic acids can make it corrode and alkali-resistant, but warm sodium hydroxide and potassium hydroxide can make it corrode and salt-resistant And grease, resistant to aliphatic hydrocarbons, insoluble in water, methanol, glycerin, etc., but can absorb alcohol and swell and cause stress cracking. It is not resistant to ketones, chlorinated hydrocarbons and aromatic hydrocarbons. Its solubility parameter is about 18.8 (J/CM3) 1/2, and it can be dissolved in many chlorinated hydrocarbons and aromatic hydrocarbons, such as dichloroethane, trichloroethylene, chloroform, toluene, etc., vinyl acetate and acetone can also make it Dissolve. Polymethyl methacrylate has good resistance to gases such as ozone and sulfur dioxide.

Weather resistance:

Polymethyl methacrylate has excellent atmospheric aging resistance. After 4 years of natural aging test, the sample has a slight decrease in tensile strength and light transmittance, a slight yellowing in color, and a decrease in crazing resistance. Obviously, the impact strength has been slightly improved, and other physical properties have hardly changed.
