Menene Gyaran Polyethylene?
Abubuwan da aka gyara na polyethylene sun haɗa da chlorinated polyethylene, chlorosulfonated polyethylene, polyethylene mai haɗin giciye da kuma gauraye iri iri.
Polyethylene Chlorinated:
Bazuwar chloride da aka samu ta wani ɗan maye gurbin hydrogen atom a polyethylene da chlorine. Ana yin chlorination a ƙarƙashin ƙaddamarwar haske ko peroxide, kuma ana samar da shi ne ta hanyar dakatar da ruwa a cikin masana'antu. Saboda bambancin nauyin kwayoyin halitta da rarrabawa, digiri na reshe, digiri na chlorination bayan chlorination, chlorine atom rarraba da sauran crystallinity na raw polyethylene, chlorinated polyethylene daga roba zuwa m filastik za a iya samu. Babban amfani shine azaman mai gyara polyvinyl chloride don inganta tasirin tasirin polyvinyl chloride. Chlorinated polyethylene kanta kuma ana iya amfani dashi azaman kayan rufewa na lantarki da kayan ƙasa.
Chlorosulfonated polyethylene:
Lokacin da polyethylene ya amsa da chlorine mai ɗauke da sulfur dioxide, wani ɓangare na atom ɗin hydrogen da ke cikin kwayoyin ana maye gurbinsu da chlorine da ƙaramin adadin rukunin sulfonyl chloride don samun chlorosulfonated polyethylene. Babban hanyar masana'antu ita ce hanyar dakatarwa. Chlorosulfonated polyethylene yana da juriya ga ozone, lalata sinadarai, mai, zafi, haske, abrasion da ƙarfin ɗaure. Yana da elastomer tare da kyawawan kaddarorin abubuwa kuma ana iya amfani dashi don yin sassan kayan aiki waɗanda ke tuntuɓar abinci.
XLPE:
Yin amfani da hanyar radiation (X-ray, electron biam ko ultraviolet irradiation, da dai sauransu) ko hanyar sinadarai (peroxide ko silicone cross-linking) don yin polyethylene na layi zuwa cibiyar sadarwa ko babban haɗin gwiwar polyethylene. Daga cikin su, hanyar haɗin gwiwar silicone yana da tsari mai sauƙi, ƙananan farashin aiki, kuma ana iya yin gyare-gyare da gyare-gyare a cikin matakai, don haka busa gyare-gyare da gyare-gyaren allura sun dace. Ƙunƙarar zafi, juriya na damuwa na muhalli da kayan aikin injiniya na polyethylene mai haɗin giciye suna inganta sosai idan aka kwatanta da polyethylene, kuma ya dace da manyan bututu, igiyoyi da wayoyi, da samfurori na rotomolding.
Haɗa gyare-gyare na polyethylene:
Bayan haɗuwa da ƙananan ƙananan polyethylene da ƙananan ƙananan polyethylene, ana iya amfani dashi don aiwatar da fina-finai da sauran samfurori, kuma aikin samfurin ya fi ƙananan polyethylene. Polyethylene da ethylene roba roba za a iya hade don samar da fadi da kewayon thermoplastik elastomers
