Thumba la pulasitiki la PE ndi lalifupi la polyethylene.Ndi thermoplastic resin polymerized kuchokera ethylene.Polyethylene ilibe fungo ndipo imakhala ngati sera.Ili ndi kukana kwambiri kwa kutentha kochepa (kutentha kotsika kogwiritsa ntchito kutentha kumatha kufika -70 ~ -100 ℃), kukhazikika kwamankhwala abwino, kukana ma acid ambiri ndi zoyambira (zosagonjetsedwa ndi makutidwe ndi okosijeni acid), zosungunulira wamba kutentha kwa firiji, kuyamwa kwamadzi pang'ono, zabwino kwambiri. ntchito yamagetsi yamagetsi.Polyethylene yothamanga kwambiri imakhala ndi zabwino zomwe zimasungunuka kwambiri, kuuma kwakukulu, mphamvu zambiri, kuyamwa kwamadzi otsika, ntchito yabwino yamagetsi, mphamvu yamagetsi yamagetsi, kukana kwambiri, kutopa, kukana kuvala, kukana kukhudzidwa, kukana kwa dzimbiri, kutalika kwakukulu, kukana kwambiri. , kukana kutayikira, kukana dzimbiri ndi zina zotero.
Makhalidwe ake ndi awa:
1.Crystal material, mayamwidwe ang'onoang'ono a chinyezi, madzi abwino, madzimadzi omwe amakhudzidwa ndi kupanikizika, kuumba kuyenera kugwiritsa ntchito jekeseni wothamanga kwambiri, kutentha kwa yunifolomu, kuthamanga kwachangu, kuthamanga kokwanira.
2.Kuvala kukana - kumapereka chitetezo cha nthawi yayitali kuti chiwonekere makina ambiri apamwamba kwambiri.
3.Impact resistance - Sungani kukhulupirika kwa maonekedwe muzogwiritsira ntchito zambiri zomwe zotsatira zake sizili zamphamvu.
4.Puncture resistance - ikhoza kupanga chotchinga cholimba chamadzimadzi, kotero kuti sichikhoza kuwononga mankhwala.
5.Kusinthasintha - sinthani mawonekedwe ambiri apamwamba.
6.Easy kugwiritsa ntchito - polyurethane imapereka njira yothetsera ntchito zambiri zovuta.
7.Zigawo zamakina osasunthika - Zida zamakina zosasunthika sizimatulutsidwa zikagwiritsidwa ntchito.
Chikwama cha PE chimakhala ndi kukana kwa dzimbiri, kutchinjiriza kwamagetsi (makamaka kutchinjiriza pafupipafupi), kusintha kwamankhwala, kusinthidwa kwa radioactive, kumatha kukulitsa ulusi wamagalasi.Ili ndi malo osungunuka otsika, kuuma kwakukulu, kuuma ndi mphamvu. Kutha kwake kumayamwa madzi ndi kochepa.Polyethylene yotsika kwambiri imakhala ndi mphamvu zamagetsi komanso zotulutsa ma radio, zofewa, kutalika, mphamvu yamphamvu komanso kutayikira kwakukulu, zokhala ndi mphamvu zambiri.Kutopa ndi kukana kuvala.Low kuthamanga polyethylene ndi oyenera kupanga dzimbiri kusamva mbali ndi kutchinjiriza mbali;High pressure polyethylene ndi yoyenera kupanga mafilimu oonda.
