Babban darajar Polyethylene Injection Molding Grade
HDPE shine resin thermoplastic wanda ba na iyakacin duniya ba wanda aka samar ta hanyar copolymerization na ethylene da ƙaramin adadin α-olefin monomer.HDPE an haɗa shi a ƙarƙashin ƙananan matsa lamba kuma saboda haka ana kiransa ƙananan matsa lamba polyethylene.HDPE galibi tsarin kwayoyin halitta na layi ne kuma yana da ɗan reshe.Yana da babban matakin crystallization da babban yawa.Yana iya jure yanayin zafi mai kyau kuma yana da kyau mai ƙarfi da ƙarfin injiniya da lalata ƙwayoyin cuta.
HDPE allura gyare-gyaren sa yana da kyau ma'auni na rigidity da taurin, mai kyau tasiri juriya da kuma m na low yanayin zafi juriya da kyau muhalli danniya crack resistanse.Gudun yana da kyau mai kyau da juriya na abrasion, da kuma kyakkyawan tsari.
Ya kamata a adana guduro a cikin busasshiyar ma'ajiyar ajiya kuma daga wuta da hasken rana kai tsaye.Bai kamata a tara shi a sararin sama ba.A lokacin sufuri, kada a fallasa kayan zuwa hasken rana mai ƙarfi ko ruwan sama kuma kada a kwashe su tare da yashi, ƙasa, tarkacen ƙarfe, gawayi ko gilashi.An haramta jigilar kayayyaki tare da mai guba, abu mai lalacewa da mai ƙonewa.
