Kiato iti Polyethylene Kiriata Kōeke QLT04 QLF39
Ko te polyethylene iti-kiato (LDPE) he kapia waihanga e whakamahi ana i te tukanga pehanga teitei na roto i te polymerization tuwhena kore utu o te ethylene, no reira ka kiia hoki ko "te polyethylene teitei".I te mea he maha nga manga roa me te poto o tana mekameka ngota, he iti ake te tioata o te LDPE i te polyethylene teitei (HDPE) he iti ake te kiato.He maamaa, he ngawari, he pai te aatete mīti me te atete paanga.LDPE he matū pūmau.He pai te atete ki nga waikawa (haunga nga waikawa kaha te waikura), te kawakore, te tote, te pai rawa o nga ahuatanga whakamaarama hiko.He iti te tere o te kuhu o te kohu.Ko te LDPE he nui te rere me te pai o te mahi.He pai mo te whakamahi i roto i nga momo tukanga tukatuka thermoplastic katoa, penei i te werohanga, te whakarewatanga, te pupuhi pupuhi, te rotomolding, te paninga, te pahuka, te wera, te wera-jet me te wera.
Taupānga
Ko te karaehe kiriata LDPE te nuinga e whakamahia ana i roto i te hanga i te kiriata whakakakahu pupuhi, te kiriata ahuwhenua ka taea te whakakotahi ki te raina iti-kiato polyethylene (LLDPE) ki te whakaputa PE whakarereke.I tua atu, ka taea te whakamahi mo te kiriata whakakikorua wera, te kiriata laminated, te kiriata mīti, te tākai hauora, te kiriata coextrusion maha-papa, te kiriata takai taumaha, te paninga paipa, te taura taura, te ararewa me te hukahuka matū teitei.
Ko te LDPE (QLT04/QLF39) he tino pai rawa atu i te kiriata kapi maramara teitei.

Mōkī, Rokiroki me te Kawenga
Ko te kapia kei roto i nga peeke raranga polypropylene kua whakakikoruatia ki roto i te kiriata.Ko te taumaha kupenga he 25Kg/peeke.Me penapena te kapia ki roto i te whare putunga maroke, kia matara atu i te ahi me te ra tika.Kaua e whakaemihia ki waho.I te wa e kawe ana, kaua e pa atu te hua ki te ra kaha, ki te ua ranei, kaua hoki e haria tahi me te onepu, te oneone, te konganuku, te waro, te karaihe ranei.Ko te kawe tahi me nga mea paitini, te waikura me nga mea mura ka tino rahuitia.
