Gabatarwa zuwa nau'ikan kaddarorin gama gari na masana'anta na PP ba saƙa
(1) Kaddarorin jiki: PP masana'anta mara saƙa ba mai guba ba ce, mara ɗanɗano fari mai babban kristal polymer, wanda shine ɗayan mafi ƙarancin nau'ikan robobi a halin yanzu.Yana da kwanciyar hankali musamman ga ruwa, kuma yawan sha ruwa a cikin ruwa shine kawai 0.01% bayan 14h.Nauyin kwayoyin yana kusan 80,000 ~ 150,000, tare da kyakkyawan tsari.Duk da haka, saboda babban raguwa, samfurori na bango na asali suna da sauƙi don sag, kuma saman samfurori yana da haske da sauƙi don launi.
(2) Mechanical Properties: PP ba saka masana'anta yana da high crystallinity da na yau da kullum tsarin, don haka yana da kyau kwarai inji Properties.Ƙarfinsa, taurinsa da elasticity ya fi na PE mai girma (HDPE).Babban fasalin shine lankwasawa juriya na gajiya (7 × 10 ^ 7) Buɗewa da rufewa na biyu suna lanƙwasa ba tare da lalacewa ba, kuma busassun juzu'i yana kama da nailan, amma yana da ƙasa da nailan ƙarƙashin lubrication na mai.
(3) Thermal yi: PP ba saka masana'anta yana da kyau zafi juriya, narkewa batu ne 164 ~ 170 ℃, da kuma kayayyakin za a iya haifuwa a zazzabi sama da 100 ℃.Karkashin aikin babu karfi na waje, ba zai lalace ba a 150 ℃.The embrittlement zafin jiki ne - 35 ℃, wanda zai faru a kasa - 35 ℃, da zafi juriya ba kamar yadda mai kyau kamar yadda PE.
(4) Chemical kwanciyar hankali: PP ba saƙa masana'anta yana da kyau sinadaran kwanciyar hankali.Bugu da ƙari, ana lalata shi da acid, yana da ingantacciyar kwanciyar hankali ga sauran abubuwan da ke haifar da sinadarai.Duk da haka, low kwayoyin nauyi aliphatic hydrocarbons, aromatic hydrocarbons, da dai sauransu na iya yin laushi da kuma kumbura PP masana'anta ba saka, da kuma sinadaran kwanciyar hankali da aka inganta tare da karuwa na crystallinity.Sabili da haka, masana'anta na PP wanda ba a saka ba ya dace don yin bututun sinadarai na Rasha da Sinanci da kayan haɗi, tare da sakamako mai kyau na lalata.
(5) Ayyukan Wutar Lantarki: Babban aikin rufin da ba a saka ba yana da kyau.Domin kusan ba ya sha ruwa, aikin rufewa ba ya shafar zafi.Yana da high dielectric coefficient.Tare da haɓakar zafin jiki, ana iya amfani da shi don yin kayan daɗaɗɗen wutar lantarki mai zafi.Rashin wutar lantarki kuma yana da girma sosai, kuma ya dace da na'urorin lantarki.Kyakkyawan juriya na ƙarfin lantarki da juriya na baka, amma wutar lantarki mai tsayi, mai sauƙin tsufa lokacin tuntuɓar tagulla.
(6) Juriya na yanayi: yadudduka marasa saka suna da matukar damuwa ga hasken ultraviolet, kuma ana iya inganta juriyar tsufa ta hanyar ƙara zinc oxide thiopropionic acid lauryl ester, carbon baki kamar madarar farin filler, da sauransu.
