Ua ntej ntawm tag nrho cov, EPP polypropylene yas ua npuas ncauj khoom yog ib yam ntawm high crystalline polymer cov ntaub ntawv uas muaj kev ua tau zoo heev, uas yog ib puag ncig tus phooj ywg, siab-resistant, buffering thiab kub-insulating khoom. EPP cov khoom muaj kev poob siab zoo heev thiab lub zog nqus, siab rov qab zoo tom qab deformation, zoo thaum tshav kub kub, tshuaj tsis kam, roj tsis kam thiab rwb thaiv tsev kub. Tsis tas li ntawd, lawv lub teeb hnyav tuaj yeem txo qhov hnyav ntawm cov khoom.
Cov ntawv thov EPP tau dhau los ua ntau dua. IT cov khoom, cov khoom siv sib txuas lus hluav taws xob, cov khoom siv ua kua ua kua, cov plasma xim TV, cov khoom siv hluav taws xob zoo, cov cuab yeej precision thiab cov ntsuas tau pib siv EPP ua cov khoom ntim. Lwm qhov tseem ceeb tshaj plaws ntawm daim ntawv thov yog ntau daim ntawv thov hauv kev lag luam tsheb: tsheb bumpers, tsheb sab poob siab cores, lub tsheb qhov rooj poob siab cores, siab heev kev nyab xeeb lub rooj zaum, me nyuam lub rooj zaum kev nyab xeeb, cuab yeej lub thawv, pob tw, armrests, hauv qab daim hlau thaub qab, hnub ci visors, ntsuas vaj huam sib luag, thiab lwm yam. (raws li kev txheeb cais, qhov nruab nrab ntawm cov yas siv hauv txhua lub tsheb yog 100 ~ 130kg, ntawm uas yog siv li 4 ~ 6kg ntawm EPP yas).
Hais txog EPE, nws hais txog foamed polyethylene, uas feem ntau hu ua pearl paj rwb. Nws yog ib yam tshiab ntawm ib puag ncig tus phooj ywg ntim khoom. Nws yog tsim los ntawm ntau cov npuas npuas uas tsim los ntawm lub cev foaming ntawm tsawg-density polyethylene resin. Nws tuaj yeem raug extruded lossis foamed, ua rau hauv daim hlau, nplooj ntawv lossis cov kav dej, thiab tom qab ntawd xuas nrig ntaus, txiav thiab sib koom ua ke. Nws muaj qhov zoo toughness, tsis yooj yim rau tawg, thiab muaj kev ua haujlwm zoo cushioning.
EPS paub zoo tshaj plaws, polystyrene, yog tsim los ntawm kev nthuav dav ua ntej, kho, molding, ziab thiab txiav. Nws tuaj yeem ua rau ntau qhov sib txawv, cov duab sib txawv ntawm cov khoom ua npuas ncauj, thiab tuaj yeem tsim ntau yam thicknesses ntawm foam boards. Dav siv nyob rau hauv kev tsim kho, thermal rwb thaiv tsev, ntim, tub yees, khoom siv niaj hnub, kev lag luam casting thiab lwm yam.
Thaum kawg, cia peb tham txog EPO, kev sib xyaw ntawm polystyrene thiab polyethylene nthuav dav. Nws yog "copolymer" ua los ntawm cov txheej txheem polymerization tshwj xeeb. Nws muaj pes tsawg leeg thiab cov qauv yog qhov tshiab. Nws muaj 30% polyethylene thiab 70% polystyrene. . PE tivthaiv feem ntau yog muab faib rau hauv txheej txheej ntawm cov khoom, uas txhawb nqa plasticization thiab kev sib txuas ntawm cov khoom, thiab PS tivthaiv feem ntau yog faib rau sab hauv ntawm cov khoom, uas muaj kev txhawb nqa zoo ntawm cov qauv ua npuas ncauj. .
