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工藝具有簡單、靈活,、經(jīng)濟(jì)和安全的特點(diǎn),;該工藝只用很少的設(shè)備就能生產(chǎn)出包括均聚物、無規(guī)共聚物和抗沖共聚物在內(nèi)的全范圍產(chǎn)品,,可在較大操作范圍內(nèi)調(diào)節(jié)操作條件而使產(chǎn)品性能保持均一,。因?yàn)槭褂玫脑O(shè)備數(shù)量少而使維修工作量小,裝置的---性,。由于流化床應(yīng)動(dòng)力學(xué)本身的,,加上操作壓力低使中物料的貯量減小,使得該工藝比其它工藝操作安全,,不存在事故失控時(shí)設(shè)備超壓的危險(xiǎn),。此工藝沒有廢料,排放到---的烴類也很少,因此對的影響非常小,,與其它工藝相比,,該工藝更容易達(dá)到、健康和安全的各種嚴(yán)格規(guī)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熱塑性三元乙丙動(dòng)態(tài)化彈性體/橡膠的主要性能:1、tpv可在-60℃~135℃溫度范圍內(nèi)使用,,應(yīng)用溫度范圍廣泛,;2、tpv硬度范圍在25a~65d之間,,可以廣泛的硬度要求,;3、tpv具有的耐候性,,具有優(yōu)異的抗老化、耐臭氧和耐紫外線性能,;4,、tpv使用時(shí)不需要化,可直接通過,、擠出,、壓延、吹塑等加工成型,,能縮短加工工藝流程,,加工成本;5,、tpv耐性能類似三元乙丙橡膠epdm,,耐油耐溶劑性能與氯丁橡膠類似;6,、tpv易于焊接,、可重復(fù)使用、,。
