Nibihe bikoresho byiza, PET cyangwa PP?

Ugereranije nibikoresho bya PET na PP, PP izaba iruta iyindi mikorere.
1. Itandukaniro nubusobanuro
PET(Polyethylene terephthalate) izina ry'ubumenyi ni polyethylene terephthalate, bakunze kwita polyester resin, ni ibikoresho bya resin.
PP.
2.Uhereye kubiranga itandukaniro
(1) PET
①PET ni amata yera cyangwa yijimye yumuhondo cyane kristaline polymer ifite ubuso bworoshye kandi bubengerana.
MaterialIbikoresho bya PET bifite imbaraga zo kurwanya umunaniro, kurwanya abrasion hamwe no guhagarara neza, kwambara gake no gukomera kwinshi, imbaraga zunamye za 200MPa, hamwe na moderi ya elastique ya 4000MPa.
MaterialIbikoresho bya PET bifite imikorere myiza yo kurwanya ubushyuhe buke kandi buke, bushobora gukoreshwa igihe kirekire mu bushyuhe bwa dogere 120 ° C, kandi bushobora kwihanganira ubushyuhe bwo hejuru bwa 150 ° C kugirango bukoreshwe igihe gito nubushyuhe buke bwa -70 ° C.
④ Ethylene glycol ikoreshwa mugukora PET ifite igiciro gito kandi ikora neza.
MaterialIbikoresho bya PET ntabwo ari uburozi, bifite umutekano muke kurwanya imiti, kandi birwanya aside idakomeye hamwe n’umuti ukomoka ku binyabuzima, ariko ntibishobora kwibiza mu mazi ashyushye na alkali.
(2) PP
①PP ni ibishashara byera byera bifite isura igaragara kandi yoroheje. Nubwoko bworoshye bwibisanzwe bikoreshwa.
MaterialPPP ifite ibikoresho byiza byubukanishi kandi birwanya ubushyuhe bwiza, kandi ubushyuhe bwo gukoresha burashobora kugera kuri 110-120 ° C.
MaterialPP ibikoresho bifite imiti ihamye kandi ntishobora gukorana nimiti myinshi usibye okiside ikomeye.
MaterialPPP ifite ubushyuhe bwo hejuru bwo gushonga nimbaraga zikaze, kandi gukorera muri firime ni hejuru.
MaterialPP ibikoresho bifite amashanyarazi meza cyane, ariko biroroshye gusaza kandi bifite imbaraga zingaruka kubushyuhe buke.
3. Itandukaniro mukoresha
PET ikoreshwa cyane, nko kuzunguruka fibre polyester, ni ukuvuga polyester; nka plastiki, irashobora gutwarwa mumacupa atandukanye; nk'ibice by'amashanyarazi, ibyuma, ibikoresho, nibindi.
Ibikoresho bya PP bikoreshwa cyane mugukora inshingekubumba ibicuruzwa, firime, imiyoboro, amasahani, fibre, coatings, nibindi, hamwe nibikoresho byo murugo, amavuta, imiti, ubwubatsi, inganda zoroheje nizindi nzego.
