Kev tsim cov txheej txheem cov khoom tsim tawm, tshuab moulding, txhaj tshuaj molding, tuag pam, khib nyiab crushing, yooj yim, sib dhos, kuaj xyuas zaum kawg thiab cia.
Raws li qhov pom ntawm cov pej xeem sawv daws, nws yog qhov nyuaj rau kev txiav txim siab seb puas muaj cov tshuaj lom neeg yas yog rau kev siv khoom lag luam lossis rau cov khoom noj tsuas yog los ntawm nws cov tsos. Cov kws tshaj lij piav qhia tias cov ntaub ntawv ntawm cov tshuaj yas yas yog feem ntau yog ua los ntawm polyethylene, polypropylene, polyester thiab lwm yam cov plastics los ntawm tshuab moulding, txhaj tshuaj molding, nqus molding thiab rotomolding. Noj polyethylene (PVC) ua piv txwv. Nws yog siv nyob rau hauv kev lag luam tsim cov yas chemical cov kas tham. Nws yog ib qho epoxy resin muaj li ntawm polyvinyl chloride resin, nplaim taws retardant thiab tus neeg sawv cev tiv thaiv kev laus. Nws muaj kev nyab xeeb ntawm nws tus kheej. Txawm li cas los xij, cov khoom siv tseem ceeb xws li nplaim taws rov qab thiab cov tshuaj tiv thaiv kab mob uas tau txhawb nqa muaj cov tshuaj lom thiab phiv. Cov tshuaj pleev polyethylene (PVC) muaj cov tshuaj tiv thaiv cov tshuaj tiv thaiv cov hmoov txhuas thiab dej cawv, ether thiab lwm cov organic solvents yuav cais cov hmoov txhuas thaum lawv kov.
Polyethylene muaj cov ntsev ntsev uas cov zaub mov ntim tau raws li cov khoom noj fritters, ncuav kib, kib ntses, khoom noj khoom noj khoom haus khoom noj khoom haus, khoom qab zib thiab khoom noj txom ncauj, nws yuav xoob cov txhuas cov qauv coj mus rau cov zaub mov, yog li polyethylene ntim tsis tuaj yeem thov Lub hnab yuav tsum muaj khoom noj, tshwj xeeb cov khoom noj muaj roj.
Tsis tas li ntawd, PVC yas txuj ci thiab khoom siv tes ua yuav maj mam yaj hydrogen chloride roj rau qhov kub dua, xws li 50 ℃ kev ua haujlwm, cov roj no ua rau muaj kev phom sij rau lub cev, yog li polyethylene kev kawm thiab cov khoom siv tes ua haujlwm tsis tsim nyog raws li cov khoom siv hloov khoom noj. Cov kws tshaj lij hais tias niaj hnub no' s cov khoom yas siv rau cov ntim khoom noj yog feem ntau ua los ntawm polyethylene (PE). Polyethylene muaj kev nyab xeeb thiab yog siv hauv cov kav dej, roj tso tsheb hlau, cov taub dej ua kua, thiab lwm tus kws tshaj lij hais tias sib nrug ntawm polyethylene yas ntim khoom, kuj tseem muaj cov khoom lag luam polypropylene yas uas tuaj yeem siv los ntim cov kua ntses, kua qaub, cawv, kua txiv hmab txiv ntoo thiab cov zaub ua zaub mov, thiab lwm yam. Cov zaub mov polyester yas ntim khoom lag luam yog qhov zoo tshaj plaws rau tuav ntau cov dej haus, Cov dej ntshiab, cov roj muaj peev xwm thiab cov khoom ua si thiab lwm yam.
