Next, Xinzhao light small edition to give you a detailed introduction
The copy table is mainly divided into: panel (Mitsubishi acrylic) + light strip (imported from Japan) + diffusion film + light guide plate (Mitsubishi acrylic plate + laser dot) + back plate (PVC)
1. what is the advantages of Mitsubishi acrylic plate?
A: the Chinese name of acrylic is transliteration of acrylics in English. The Chinese common names are acrylic and akuli. It is a general term for acrylic and methylacrylic chemicals. It includes monomer, plate, granular material, resin and composite material. Acrylic plate is made of MMA monomer, that is, PMMA sheet organic glass, which is a kind of organic glass processed by special technology. It has the reputation of "plastic Queen". The research and development of acrylic has a history of more than 100 years.
Acrylic has good light transmittance, is colorless transparent plexiglass plate, with light transmittance of 92% or more; It has excellent weatherability and strong adaptability to natural environment. Even long time exposure to sunlight and wind and rain will not change its performance, and its anti-aging performance is good. The processing performance is good, which is suitable for machining and easy to be hot formed; Acrylic panels can be dyed and the surface can be painted, silk or vacuum coated. It is non-toxic, even if it is in long-term contact with people, it is harmless. The gas produced during combustion does not produce toxic gas. And has excellent weather resistance, acid resistance, alkali resistance.
Advantages:
1. Outdoor weather resistance, can protect long-term weather resistance, not fade, service life of up to 5-8 years.
2. Transparent plate is crystal clear and transparent, 200 times more than glass products, and there is almost no risk of fracture.
3. The surface is glossy, smooth and smooth, with a light transmittance of 93%, excellent light transmission, soft light and bright.
4. Green environment protection and waste materials can be completely recycled, and the recycling is simple and easy. Light transmission performance is good, corresponding to reduce light source products, power saving, and reduce use costs.
5. Excellent surface hardness and scratch resistance, the product has good protection for the built-in light source, and extends the service life of the light source products.
6. Good chemical resistance, superior to most other plastic materials.
7. Easy to clean, maintain, ensure the appearance of signboards and light boxes are new all year round, reasonable design, rain proof and moisture proof, open structure, easy to repair.
8. Fire resistance: it is not spontaneous combustion and has self extinguishing property.
2. What is PVC?
Answer: PVC: it is the initiator of vinyl chloride monomer in peroxide, azo compound and so on; Or polymer formed by the reaction mechanism of free radical polymerization under the action of light and heat. Vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resin.
PVC is a white powder with amorphous structure, with small branching degree, relative density of about 1.4, glass transition temperature of 77-90 ℃, decomposition at 170 ℃. The stability of light and heat is poor
If the temperature is above 100 ℃ or exposed to the sun for a long time, hydrogen chloride will be decomposed and further Autocatalytic Decomposition will be generated, causing discoloration, and the physical and mechanical properties also decrease rapidly. Stabilizer must be added in practical application to improve the stability of heat and light.
The molecular weight of PVC produced in industry is generally in the range of 50000-11000, which has a large dispersibility, and the molecular weight increases with the decrease of polymerization temperature; Without fixed melting point, the temperature of 80-85 ℃ began to soften, 130 ℃ to viscoelastic state, and 160-180 ℃ to viscous flow state; The tensile strength is about 60MPa and the impact strength is 5-10kj / m2; It has excellent dielectric properties.
PVC used to be the most widely used plastic in the world. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers, etc.
Advantages:
Light: PVC material only has 1/10 of cast iron, easy to transport, easy to install, and reduce cost.
Excellent chemical resistance: PVC has excellent acid-base resistance, except for the strong acid-base near saturation point or strong oxidising agents atmaximun.
Non conducting: PVC materials can not conduct electricity, nor be corroded by electrolysis and current, so it does not need to be processed twice.
It can not be burned, nor combustion supporting, and there is no fire-fighting concern.
Durable: good weather resistance, and can not be corrupted by bacteria and fungi.
