PE: Ko te resin Polyethylene PE he koretake-kore, kaore hoki he haunga he pungarehu ma, he paura ranei, me te ahua ma o te waiu me te waxy. he mura, he 17.4% noa te maatauranga okiha, he paowa iti me te turuturu i te wa o te weranga, kowhai i te mura me te kikorangi o raro.
Kakara Paraffin; te mimiti o te wai (polyethyleneKei roto i te PE polyethylene PEte iti o nga hononga takirua me nga roopu ether i roto i te ngota ngota, no reira kaore i te pai te awangawanga o te pe, te ra me te ua ka ruhiruhia, me taapiri i nga antioxidants, nga kaiwhakawhanake marama hei whakapai ake he pai, ka tae te mahana o te whakaheke i te 300â "ƒ neke atu ranei; engari ka nui ake te mahana i te 50â "ƒ i te waahi kua wera, na te wera o te oxygen e kawe te uruparenga, no reira me whakauru ki nga antioxidants hei whakapai ake Hei tauira, ko te antioxidant matua 1010 me te antioksidariant 168; ko te aukati i te wera o te PE i te rangi kaore i te pai, ka pai ake me te piki o te taumaha o te ngota ngota me te karaehe; engari ko te awangawanga awangawanga iti o te PE he tino pai, me te paemahana iti o te mahana i raro -50â "ƒ, me te pikinga o te taumaha o te ngota, ka tae te mea o raro ki te -140â" ƒ; he teitei ake te kawe waiariki o PE, HDPE> LLDPE> LDPE; he nui te whakarea whakarahinga rarangi o te PE, ko tehea te mea nui rawa atu i waenga i nga momo kirihou, me te teitei Ki runga (20 ~ 24) × 10 -5 -5 K -1 -1, LDPE> LLDPE> HDPE.
1. He iti-kiato polyethylene LLDPE Iti-itipolyethylene LLDPE: Ko te mekameka rāpoi o te polyethylene iti-kiato he peka roa me te poto me te tioata Iti, ko te taumaha o te ngota he 50,000 ki te 500,000, he waini ma te waireka o te wainiini kore, kaore he paitini, he waahi ngohengohe iti, he waatea pai, he awangawanga awhi, he pai te awangawanga o te pāmahana iti, ka taea ki te -60â "ƒ Te mahi i -80â"., he hiko hiko pai.
2. He ngoikore te kaha o te miihini LDPE, he iti te aukati i te wera, he ngoikore te awangawanga o te taiao e pakaru ana i te awangawanga, te piri, me te taarua, me te hiahia kia aata whakapai ake te mahi. LDPE Tino iti te mimiti o te wai, tata kaore he mimiti o te wai, tino pumau te matū, penei i te waikawa ki te waikawa, te alkali, te tote, me nga whakarewa koiora. He tino uruhanga ki te hauhā me te haunga o te koiora, engari te ngoikore o te urunga ki te kohu wai me te hau. He ngawari ki te wera, he kakara paraffin te wera, he ngawari ki te whakaheke me te huri i te tae i raro i nga mahi a te ra me te wera.
3. HDPE polyethylene-nui-teitei:HDPE polyethylene-nui-teitei: He waxy maamaa te waxy translucent waxy, ko te tohu o te peka o te HDPE te mea iti rawa, a he kikii te kaha o te ngota ngota, no reira he teitei te kiato, he tiketike te karaehe. He nui te awangawanga o te HDPE, te aukati hinu, te aukati i te uruhanga o te korohuu me te aukati i te awangawanga o te taiao, te aukati hiko, te awangawanga paanga me te aukati makariri Kei te kaha te HDPE a he pai ake te mahi koroheketanga i te PP, me te mahana o te mahi he teitei ake i te PVC me te LDPE. He iti nei te ngongo o te HDPE mo te wai, kaore he paitini, he pumau tino matū, ana he iti te uruhanga o te kiriata nei ki te kohu wai me te hau.
