Txawm hais tias tsib lo lus Askiv EPP, EPE, EPS, thiab EPO zoo sib xws, cov khoom uas lawv sawv cev yog txawv kiag li.
Tom ntej no, peb yuav tshawb xyuas cov yam ntxwv ntawm EPP hauv qhov tob thiab luv luv qhia lub ntsiab lus ntawm plaub lub npe.
1. EPP, lo lus no muaj ntau lub ntsiab lus.
Nws tuaj yeem xa mus rau qhov chaw nres nkoj txuas ntxiv, cov khoom siv polypropylene yas ua npuas ncauj, lossis kev cog lus txuas ntxiv, qhov kawg phaj muaj peev xwm, thiab PHP project txhim kho compiler. Hauv tsab xov xwm no, peb feem ntau tham txog kev siv EPP li polypropylene yas ua npuas ncauj khoom.
EPP yog cov khoom siv crystalline polymer zoo heev nrog kev tiv thaiv ib puag ncig zoo, compression tsis kam, cushioning thiab rwb thaiv tsev kub. Nws cov khoom tsis tsuas yog qhia tau zoo heev poob siab kuj thiab lub zog nqus cov yam ntxwv, tab sis kuj muaj peev xwm sai sai rov qab mus rau lawv cov qub zoo tom qab deformation, thiab muaj zoo kub tsis kam, tshuaj tsis kam, roj kuj thiab kub rwb thaiv tsev. Tsis tas li ntawd, EPP yog lub teeb hauv qhov hnyav thiab tuaj yeem txo qhov hnyav ntawm cov khoom.
Daim ntawv thov ntau ntawm EPP tau dhau los ua dav dav, npog IT khoom, khoom siv hluav taws xob sib txuas lus, LCD saib, ntshav xim
TVs thiab lwm yam. EPP cov ntaub ntawv kuj tau siv dav hauv kev ntim khoom ntawm cov khoom siv hluav taws xob thiab cov cuab yeej precision. Nws yog ib qho tsim nyog hais tias kev lag luam tsheb tau dhau los ua lwm qhov tseem ceeb ntawm EPP daim ntawv thov. EPP cov ntaub ntawv yog dav siv hauv tsheb bumpers, sab shockproof cores, qhov rooj shockproof cores thiab lwm yam, nrog rau kev ruaj ntseg lub rooj zaum thiab menyuam yaus lub rooj zaum. Raws li kev txheeb cais, qhov nruab nrab ntawm cov yas siv hauv txhua lub tsheb yog li 100130kg, ntawm cov yas EPP yog li 46kg.
Tsis tas li ntawd, EPP kuj tau siv dav hauv kev ua qauv aviation. Txawm li cas los xij, nws tus nqi tseem ceeb tau txwv qhov muaj koob npe ntawm EPP cov qauv dav hlau ua los ntawm cov phooj ywg ua qauv rau qee yam.
2. EPE, uas yog, nthuav polyethylene, tseem hu ua pearl paj rwb.
Cov khoom no tsis yog tsuas yog ib puag ncig tus phooj ywg, tab sis kuj muaj lub cev zoo heev. Its production process involves the physical foaming of low-density polyethylene grease, thereby forming countless independent bubbles. Cov khoom no tuaj yeem raug extruded rau hauv daim hlau los yog cov ntawv, los yog foamed rau hauv cov kav dej, thiab tom qab ntawd stamped, txiav thiab sib txuas, thiab thaum kawg nthuav tawm zoo toughness thiab cushioning zog, thiab tsis yooj yim rau tawg.
3. EPS, lossis polystyrene, muaj cov txheej txheem tsim khoom uas suav nrog ua ntej- ntau lawm, kev laus, molding, ziab thiab txiav.
Cov khoom siv no tuaj yeem ua rau hauv cov khoom siv yas ua npuas dej ntawm cov khoom sib txawv thiab cov duab, thiab tuaj yeem tsim ua npuas dej ntawm ntau yam thicknesses. EPS yog dav siv nyob rau hauv ntau lub teb xws li kev tsim kho, rwb thaiv tsev, ntim, tub yees, khoom siv niaj hnub thiab kev lag luam casting.
4. EPO, ib qho tshwj xeeb polymer, yog tsim los ntawm cov txheej txheem polymerization tshwj xeeb.
Nws yog ib qho sib xyaw ntawm 30% polyethylene thiab 70% polystyrene, uas cov PE tivthaiv feem ntau yog muab faib rau hauv txheej txheej ntawm cov khoom, uas pab plasticization thiab kev sib txuas ntawm cov khoom, thaum PS tivthaiv feem ntau faib rau hauv cov khoom, muab kev txhawb zog rau cov qauv ua npuas ncauj.
