Qaab dhismeedka Molocalical:

Sifooyinka kiimikada:

PolycarbonateWaa amorphous, dhadhan la'aan, ur, polylmoplaster-ka aan sun-tolmoplaspal-ka ah, kuleyl heer sare ah, gaar ahaan adkaata, adkaanta, hagaynta ayaa yar, cabirka sheyga waa mid deggan, cabirku waa mid deggan yahay. Xoogga ay saameyntu saameysey ee 44kj / mz, tsile xoog> 60mpa. Isu caabbinta kuleylka polycarbonate waa wanaagsan tahay, waxaa loo isticmaali karaa waqti dheer - 60 ~ 120 ℃, heerkulka kuleylka kuleylka ee 145 ~ 150 ℃, majiro dhibic dhalaalaya, 220 ~ 230 ℃ waa dowlad dhalaalaysa . Heerkulka burburka kuleylka> 310 ℃. Sababo la xiriira adkaanta silsiladda molikalalbalar, jaceylka jahwareerka ayaa aad uga badan kan guud ee heerkulka guud.

Codsi:

PolycarbonateS Waa ay si balaayitaan ah loo isticmaalaa warshadaha casriga ah inay yeeshaan heerkul wanaagsan oo caabbinta saameynta saamiga ah. Balaastiini waxay si gaar ah ugu fiican tahay in lala shaqeeyo farsamooyinka qeexan ee caadiga ah (la isku duro, dib-u-soo-saarista tuubooyinka ama dhululubooyinka iyo heerkulka. Waxaa sidoo kale loo istcimaalaa marka loo baahan yahay daah furnaanta indhaha, oo leh in kabadan 80% gudbinta xargaha 1560-NM Waxay leedahay guryaha iska caabinta kiimikada ee dhexdhexaadka ah, oo kimikal ahaan u adkaysta aashitada kulul iyo aalkolada. Waa mid si xun u adkaysata ketones, xasaasiyo, iyo aashito isku-dhafan. Khasaaraha ugu weyn ee la xidhiidha heerkulka ku-meelgaarka ah ee polycarbonarbonarbon-ka waa heerkulka kala-guurka ee polycarbonarbon-ka (TG> 40 ° C), laakiin waxaa wali si weyn loogu isticmaalaa maadada qiimaha-yar iyo sidoo kale lakab aan caadi ahayn.
