Te taura polyethylene /PP e whakamahia ana i roto i te oranga o ia ra

He pai te noho matū o te polyethylene, ka taea e ia te aukati i te waikawa nitric dilute, te waikawa sulfuric dilute me tetahi kukū o te waikawa pūhaumāota, waikawa pūwaiwai, waikawa ūkuikui, waikawa formic, waikawa acetic, haukinia, amine, hauwai peroxide, konutai waihā, pāhare pāporo waihā me ētahi atu rongoā i te pāmahana rūma.Engari ehara i te ātete ki te waikura waikura kaha, penei i te waikawa sulfuric fuming, te waikawa nitric concentrated, te waikawa chromic me te ranunga waikawa sulfuric.I te pāmahana rūma, ka whakaputa nga whakarewa i te horo o te polyethylene puhoi, me te 90 ~ 100 ℃, Ko te waikawa sulfuric concentrated me te waikawa nitric concentrated ka tere te whakakore i te polyethylene, ka pakaru, ka pirau ranei.Ko te polyethylene he ngawari ki te whakaahua i te waiora, te waiariki waiariki, te ozone decomposition, te ngawari ki te whakaheke i raro i te mahi o te rama ultraviolet, te waro pango he pai te whakamarumaru o te rama. polyethylene.Ko nga tauhohenga penei i te honohono, te wehenga mekameka me te hanganga o nga roopu haunga ka puta i muri i te iraruke.

Ko te taura polyethylene no te waikura waikore alkane, he pai te pumau matū.I te pāmahana rūma, te waikawa, te kawakawa, te wairewa wai tote te aukati i te waikura, engari ehara i te waikura kaha penei i te waikawa sulfuric, te waikawa nitric me te waikawa chromic.Ko te polyethylene kaore e rewa i roto i nga whakarewa whanui kei raro. 60 ℃, engari me te hauwai aliphatic, te hauwai kakara, te hauwai hauhau me etahi atu whakapiri mo te wa roa ka pupuhi, ka pakaru ranei.

Ko te taura polyethylene te hanga o te polyethylene, te polyethylene mo te ahotea o te taiao (matū me te mahi miihini) he tino tairongo, he kino atu te koroheketanga o te wera i te hanganga matū polymer me te tarai tukatuka.Ka taea te tukatuka i te polyethylene e te tikanga whakakikorua thermoplastic noa. i roto i te hanga kiriata, taputapu takai, ipu, paipa, monofilament, waea me te taura, nga mea e hiahiatia ana i ia ra, me etahi atu, ka taea te whakamahi hei taputapu whakamarumaru teitei mo te TV, radar, me etahi atu. o te polyethylene kua tere whakawhanakehia, e kiia ana mo te 1/4 o te katoa o te hanga kirihou.I te tau 1983, ko te katoa o te kaha o te polyethylene o te ao ko te 24.65 mT, ko te kaha o te tipu kei te hangaia he 3.16 mT.Ko nga hua tatauranga hou i te tau 2011, kua eke te kaha ki te whakaputa i te ao ki te 96 MT, ko te ahuatanga whanaketanga o te hanga polyethylene e whakaatu ana kei te neke haere te mahi me te kohi ki Ahia, a kei te noho a Haina te maakete kaihoko tino nui.
