詳細內容：PC/ABS FR410MT ╖PC/ABS FR410MT PC/ABS FR410MT ╖PC/ABS FR410MT PC Acrylic is a by-product extracted from deep sea oil. In fact, a careful understanding of acrylic material will not be so magical. It is also a kind of plexiglass. The common transparent mobile phone display rack is made of it. Although it is also a kind of glass, but the acrylic is not as "fragile" as glass, the impact resistance is 200 times stronger than the ordinary glass, and almost will not break. Its load-bearing capacity changes with the change of thickness, and the thicker and stronger it is. During the interview, the reporter found that a acrylic table was completely transparent. Once the glass furniture was supported, stainless steel and other load bearing materials were selected. All of them were acrylic from the top to the feet, so its affordability is not very common. Acrylic has a hard side, but also has the characteristics of flexible, it is very suitable for modeling, bending angle arc can be achieved through the technology. It has better insulation than glass, unlike glass, which is "cool", but it also leads to its poor heat dissipation. This material is most afraid of sharp scratches, but this kind of scratch is also easy to repair, the ordinary white toothpaste wiping. PMMA Crack and break. In addition, the special acrylic board for sanitary ware has strong decay resistance and light transmittance, and because the pigment can be dissolved in the plate, its color is very stable, and it is not easy to fade in long term sunlight and rain. Therefore, the special acrylic plate for sanitary ware is widely used in other industries in addition to indoor and outdoor decoration. Due to its low hardness, poor heat resistance and low elongation, the ordinary acrylic board is easy to crack, fragile, and easy to deform, and its color is not stable. It is easy to get fuzzing during its use. The molded bathtub is usually prone to color change due to the large tensile at the bottom. It is usually seen that the corner of the bottom is white, yellow and so on. [2] And the ABS acrylic composite board is made of ABS plate on the two sides of the acrylic composite plate. It is easily observed at the edge of the flanged edge of the sanitary ware. As the ABS acrylic composite plate is made of two different materials, the shrinkage rate is inconsistent. After long term cold and hot change, it is easy to produce stratification. Thirdly, because the surface of ABS board is only a few millimeters thick acrylic, its stability and wear resistance are all poor, so it is easy to produce "white" or other discoloration phenomena when molding. Physical property table Test method of physical performance rating unit system Density 1.19 g/cm3 ISO1183 Melt flow rate (230 C/3.8 kg) 3.2 g/10 min ISO 1133 Process characteristics Test method of physical performance rating unit system Specific gravity 1.18 ASTM D792 Melt flow rate (230 C/3.8 kg) 20 g/10 min ASTM D1238 1., polymethyl methacrylate contains polar side methyl, which has obvious hygroscopicity. The water absorption rate is generally 0.3%-0.4%, and it must be dried before forming. The drying condition is 80 4-5h -85 dry. 2., polymethyl methacrylate has obvious and non Newtonian fluid characteristics in the temperature range of molding, and the melt viscosity will decrease obviously with the increase of shear rate. Melt viscosity is also sensitive to the change of temperature. Therefore, for the molding process of polymethyl methacrylate, the viscosity of the melt can be obviously reduced and the fluidity can be obtained by improving the molding pressure and temperature. PPA The company that produces amorphous PPA resin includes: Amoco characteristic product company (Amodel card), DuPont Co (Zytel brand), Dynamit Nobel company (Trogamid card). Amoco and Mitsui Petrochemical Industries Co produce Amodel and Arlen brand PPA resin respectively Introduce the return directory of this section [1]EMS-GRIVORY uses the name of GreenLine to sell a variety of biobased polyamides, which are or all made from renewable materials. The "GreenLine" product consists of the following series of products: Grivory HT (polyphthalic two formamide) Grilamid TR (amorphous transparent polyamide) Grilamid 1S (PA1010) Grilamid 2S (PA610) GreenLine provides a series of special features, from very flexible to extremely rigid, from high heat resistance or hydrolysis resistance to complete transparency. The main goal of GreenLine developed by EMS-GRIVORY is to provide customers with products made from renewable materials. These products have excellent characteristics and have proved to mitigate the environmental impact in the production process. From a technical point of view, the GreenLine product is the first in the crude polyamide. 　　Grilamid 1S PA1010 和 Grilamid 2S PA610 　　Main features: Biological content from high to high Features are similar to PA12 Low hygroscopicity From flexible to very rigid (enhanced), cold resistance Good anti ultraviolet and chemical resistance Low density For injection and extruding In the process of injection molding or sandwich injection, there is good adhesion between Grilamid 1S PA1010 and the biological base GRILAMID BTR. Grilamid TR, amorphous transparent polyamide Main features: High biological content Excellent transparency and natural color Compared with most other amorphous thermoplastic plastics, it has excellent chemical resistance and plastic online plastic Encyclopedia PPO Modified Without modification of polyphenylene oxide (PPO) resin has good mechanical properties, electrical properties, heat resistance, flame resistance and chemical stability, but its poor solvent resistance and products are prone to stress cracking, low impact strength, it also has a fatal weakness -- high melt viscosity, processing range, cannot adopt pure PPO resin injection molding, which greatly limits its application. In order to overcome these shortcomings, or to give them new performance, a variety of modifications have been made to the PPO. The method has two kinds of chemical (copolymerization, block, grafting, mesh and so on) and physical (blending, filling, reinforcing and microfoaming). Chemical modification mainly includes: (1) modify the structure of PPO, such as bromination, phosphorylation, sulfonylation, carboxylation and so on, to improve the solubility and permeability of PPO for the application of membrane materials, or to give PPO Flame Retardancy for flame retardants. (2) the main chain or terminal group of PPO reacts with the small molecules with functional groups, giving the PPO a certain polarity and reactivity to the compatibilizer of the PPO alloy. (3) PPO and other polymers or small molecules were obtained by block or graft copolymerization to obtain new materials or compatibilizer for PPO alloys; the most active research in physical modification of PPO is The alloying of PPO mainly includes: (1) the first generation PPO alloy was prepared by blending PPO with PS in a wide range of composition and blending with polymers with styrene units to prepare PPO/PS type alloys. (2) through the blending with other engineering plastics, such as polyamide (PA), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyphenylene sulfide (PPS) and so on, high performance PPO alloy, the second generation PPO alloy, is prepared. In addition, polyphenylene ether alloy can be divided into: polyphenylene ether alloy according to the compatibility between the components: (1) the compatible system, mainly refers to PPO/PS; (2) incompatible systems, including PPO/PA, PPO/PBT, PPO/PET, PPO/ polytetrafluoroethylene (PTFE), PPO/ polyolefin (PO) and so on. (3) partially compatible system, including PPO/ polycarbonate (PC), PPO/PPS PPO/, styrene butadiene styrene copolymer (SBS), PPO/ acrylonitrile butadiene styrene copolymer (ABS), PPO/ (PMMA, PPO/) poly styrene acrylonitrile copolymer (SAN) etc..
