Abubuwan Sinadarai:

Polycarbonateshi ne amorphous, m, wari, mara guba m thermoplastic polymer, yana da kyau kwarai inji, thermal da lantarki Properties, musamman tasiri juriya, mai kyau tauri, creep ne kananan, samfurin size ne barga.Ƙarfin tasirin sa na 44kj / mz, ƙarfin tensile> 60MPa.polycarbonate zafi juriya yana da kyau, za a iya amfani da na dogon lokaci a - 60 ~ 120 ℃, zafi deflection zafin jiki 130 ~ 140 ℃, gilashin mika mulki zafin jiki na 145 ~ 150 ℃, babu wani fili narkewa batu, a 220 ~ 230 ℃ ne narkakkar jihar. .Thermal bazuwar zafin jiki> 310 ℃.Saboda tsananin sarkar kwayoyin halitta, dankon narkensa ya fi na janar thermoplastics.

Aikace-aikace:

Polycarbonates robobi ne da ake amfani da su sosai a masana'antar zamani suna da kyakkyawan zafin jiki da juriya mai tasiri.Wannan filastik yana da kyau musamman don yin aiki tare da ƙarin fasahohin ma'anar na al'ada (na yin gyare-gyaren allura, extrusion cikin tubes ko cylinders da thermoforming).Hakanan ana amfani dashi lokacin da ake buƙatar bayyananniyar gani, tare da watsa sama da 80% har zuwa kewayon 1560-nm (gajeren kewayon infrared infrared).Yana da matsakaicin kaddarorin juriya na sinadarai, kasancewa mai juriya da sinadarai ga diluted acid da alcohols.Yana da ƙarancin juriya ga ketones, halogens, da acid mai tattarawa.Babban rashin lahani da ke da alaƙa da polycarbonates shine ƙananan zafin canjin gilashin (Tg> 40 ° C), amma har yanzu ana amfani da shi azaman ƙarancin farashi a cikin tsarin microfluidic kuma har ma a matsayin Layer na hadaya.
