Ibyiza
Umuvuduko mwinshi wa polyethylene cyangwa HDPE nigiciro gito, cyera cyamata, igice cya trmoplastique.Nibihinduka ariko birakomeye kandi birakomeye kuruta LDPE kandi bifite imbaraga zingirakamaro hamwe no kurwanya puncture.Kimwe na LDPE, ifite kandi imiti irwanya imiti, ibintu byiza byo kurekura, hamwe numwuka mwiza ariko inzitizi mbi ya gaze hamwe nikirere.Izindi mbogamizi cyangwa ibibi zirimo: bitewe no guhangayika, bigoye guhuza, gutwikwa, nubushobozi buke bwubushyuhe.
Mubisanzwe, polyethylene yuzuye cyane ni umurongo kandi rero ni kristaline kuruta LDPE.Ubusumbane bwo hejuru buganisha ku bushyuhe bwo hejuru bwa serivisi bugera kuri 130 ° C kandi bikavamo uburyo bwiza bwo guhangana n’ibikurura.Ubushyuhe bwa serivisi yo hasi ni hafi -40 ° C.
HDPE ikunda gukomera kuruta izindi firime polyethylene, nikintu cyingenzi kiranga paki zigomba kugumana imiterere yazo.HDPE iroroshe gutunganya kandi irashobora kuvangwa nizindi polymers hamwe na / cyangwa inyongeramusaruro, nka (hejuru yubuvuzi) yuzuza, izindi polyolefine (LDPE, LLDPE), hamwe na pigment kugirango ihindure imitungo yibanze.
Porogaramu
Filime ya HDPE ikoreshwa kenshi mubikorwa byinshi nka LDPE na LLDPE kandi rimwe na rimwe iba ihujwe na LDPE kugirango ihindure imitungo yayo.HDPE ikwiranye na porogaramu aho hakenewe imbaraga nyinshi zo guhagarika no kwikuramo kandi / cyangwa mugihe bikenewe gukomera no gukomera.Kimwe na LDPE, HDPE ifite imbaraga zingaruka zingirakamaro no kurwanya ruswa.
Bitewe numunuko muke, imiti myinshi irwanya imiti nubusembure, amanota menshi ya PE arakwiriye gupakira porogaramu nkuko amategeko ya FDA abiteganya.Bitewe no guteka cyane, amanota menshi arashobora guhindurwa mumazi abira.
Ubusanzwe porogaramu ya firime ya HDPE irimo imifuka;imirongo;ibiryo n'ibipfunyika;firime yubuhinzi nubwubatsi.
Mu myaka yashize, HDPE yungutse isoko cyane cyane kubera imitungo yayo yo hasi, itanga ama firime yoroheje no gupakira (ni ukuvuga ibikoresho bike bikoreshwa) bitanga imikorere ingana.
Filime ya HDPE mubusanzwe 0.0005 "kugeza 0.030".Baraboneka mumabara asobanutse cyangwa adasobanutse.HDPE iraboneka kandi hamwe na anti-static, flame retardant, hamwe na ultraviolet.
