chemical formula: [-nh (ch2) 6 - nhco (ch2) 4co]n - corrosion resistance to acid, alkali, most inorganic saline solution, halogenated alkane, hydrocarbons, esters, ketones, etc.、impact resistance: 200 times the glass product, with almost no risk of breaking.、2. it has outstanding electrical insulation&water resistance. it has good wear resistance&electrical properties,&has good dimensional stability. its lectric property ranks first in plastic.、polyamide resin, the english name is polyamide, referred to as pa. it is commonly known as niron (nylon), which is contained in the repeating unit of the main chain of the macromolecule、it can be preserved for a long time, never fade&use for 5~8 years.、another problem is "scaling". when colorants are dyed, they are freed from the system due to their poor compatibility/incompatibility. they are deposited on the surface of the processing equipment, such as the inner wall of the extruder&the inner wall of the hole.、melt flow rate (330 degree c/2.16 kg)、melting temperature: the melting point of pp is 160-175 c, the deco-ition temperature is 350 c, but the temperature setting can not exceed 275 c during the injection processing. the temperature of the melting section is best at 240.、1.3 application fields、for injection&extruding、the introduction of all transparent chassis&multicolor chassis 、grivory ht (polyphthalic two formamide)、pp工艺具有简单、灵活、经济和安全的特点;该工艺只用很少的设备就能生产出包括均聚物、无规共聚物和抗冲共聚物在内的全范围产品,可在较大操作范围内调节操作条件而使产品性能保持均一。因为使用的设备数量少而使维修工作量小,装置的---性。由于流化床应动力学本身的,加上操作压力低使中物料的贮量减小,使得该工艺比其它工艺操作安全,不存在事故失控时设备超压的危险。此工艺没有废料,排放到---的烃类也很少,因此对的影响非常小,与其它工艺相比,该工艺更容易达到、健康和安全的各种严格规范。、back pressure
、7. the transparency of polypropylene products is better than that of high density polyethylene.、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,&almost will not break. its load-bearing capacity changes with the change of thickness,&the thicker&stronger it is. during the interview, the reporter found that a acrylic table was completely transparent. once the glass furniture was supported, stainless steel&other load bearing materials were ed. 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 scr---hes, but this kind of scr---h is also easy to repair, the ordinary white toothpaste wiping.、6. the electrical insulation is good.、runner&gate: the location of the gate is very important because of the short solidification time of the pa66. the gate diameter of the gate should not be less than 0.5*t (here t is the thickness of the plastic part).、flexural modulus 8270 mpa astm d790、tpv热塑性三元乙丙动态化弹性体/橡胶的主要性能:1、tpv可在-60℃~135℃温度范围内使用,应用温度范围广泛;2、tpv硬度范围在25a~65d之间,可以广泛的硬度要求;3、tpv具有的耐候性,具有优异的抗老化、耐臭氧和耐紫外线性能;4、tpv使用时不需要化,可直接通过、挤出、压延、吹塑等加工成型,能缩短加工工艺流程,加工成本;5、tpv耐性能类似三元乙丙橡胶epdm,耐油耐溶剂性能与氯丁橡胶类似;6、tpv易于焊接、可重复使用、。
