Kodi Polyethylene Yosinthidwa Ndi Chiyani?

Kodi Polyethylene Yosinthidwa Ndi Chiyani?

Mitundu yosinthidwa ya polyethylene makamaka imaphatikizapo chlorinated polyethylene, chlorosulfonated polyethylene, cross-linked polyethylene ndi blended modified mitundu.

Polyethylene ya Chlorinated:

Koloridi mwachisawawa wopezedwa mwa kusintha pang'ono maatomu a haidrojeni mu polyethylene ndi klorini. Chlorination ikuchitika pansi pa mwambo wa kuwala kapena peroxide, ndipo makamaka amapangidwa ndi amadzimadzi kuyimitsidwa njira mu makampani. Chifukwa cha kusiyana kwa kulemera kwa maselo ndi kugawa, digiri ya nthambi, digiri ya chlorination pambuyo pa chlorine, kugawa kwa atomu ya klorini ndi crystallinity yotsalira ya polyethylene yaiwisi, chlorinated polyethylene kuchokera ku rubbery kupita ku pulasitiki yolimba imatha kupezeka. Ntchito yaikulu ndi monga chosinthira cha polyvinyl kolorayidi kuti apititse patsogolo kukana kwa polyvinyl chloride. Chlorinated polyethylene yokha itha kugwiritsidwanso ntchito ngati zida zotchingira magetsi komanso zinthu zapansi.

Chlorosulfonated polyethylene:

Pamene polyethylene amachitira ndi klorini munali sulfure woipa, mbali ya maatomu wa haidrojeni mu molekyulu m`malo ndi klorini ndi pang`ono sulfonyl kolorayidi magulu kupeza chlorosulfonated polyethylene. Njira yayikulu yamafakitale ndi njira yoyimitsa. Chlorosulfonated polyethylene imagonjetsedwa ndi ozoni, dzimbiri la mankhwala, mafuta, kutentha, kuwala, abrasion ndi mphamvu zamanjenje. Ndi elastomer yokhala ndi katundu wabwino wokwanira ndipo imatha kugwiritsidwa ntchito kupanga zida zomwe zimalumikizana ndi chakudya.

XLPE:

Kugwiritsa ntchito njira ya radiation (X-ray, electron mtengo kapena ultraviolet irradiation, etc.) kapena njira yamankhwala (peroxide kapena silicone cross-linking) kupanga polyethylene yozungulira kukhala netiweki kapena polyethylene yochuluka yolumikizidwa. Pakati pawo, njira yolumikizira silikoni ili ndi njira yosavuta, yotsika mtengo yogwiritsira ntchito, ndipo kuumba ndi kulumikiza kungathe kuchitidwa pang'onopang'ono, kotero kuti kuwombera ndi jekeseni ndizoyenera. The kukana kutentha, chilengedwe kupsinjika maganizo akulimbana kukana ndi mawotchi katundu wa polyethylene mtanda zogwirizana kwambiri bwino poyerekeza ndi polyethylene, ndipo ndi oyenera mipope lalikulu, zingwe ndi mawaya, ndi rotomolding mankhwala.

Kusintha kwa polyethylene:

Pambuyo kusakaniza liniya otsika osalimba polyethylene ndi otsika kachulukidwe polyethylene, angagwiritsidwe ntchito pokonza mafilimu ndi zinthu zina, ndipo mankhwala ntchito bwino kuposa otsika osalimba polyethylene. mphira wa polyethylene ndi ethylene propylene amatha kusakanikirana kuti apange mitundu yosiyanasiyana ya mphira.
