Lub tshuab txhaj tshuaj molding yog lub tshuab ua kom sov, melts, compresses thiab txhaj tshuaj thermoplastic lossis thermosetting cov ntaub ntawv yas rau hauv pwm, cia lawv txias thiab khov rau hauv cov khoom ntawm ntau yam duab. Kev txhaj tshuaj molding tshuab yog dav siv nyob rau hauv ntau yam lag luam, xws li tsheb, khoom siv hauv tsev, khoom siv hluav taws xob, kev kho mob, kev tsim kho, ntim, thiab lwm yam. cov ntaub ntawv.
Cov ntaub ntawv txhaj tshuaj yog xa mus rau cov ntaub ntawv yas uas tuaj yeem ua tiav rau hauv cov khoom los ntawm kev txhaj tshuaj molding tshuab ntawm qhov kub thiab txias. Muaj ntau hom kev txhaj tshuaj molding cov ntaub ntawv, uas tuaj yeem muab faib ua pawg hauv qab no raws li lawv cov qauv tshuaj thiab cov yam ntxwv ua haujlwm:
- Thermoplastic plastics: yog hais txog cov yas uas tuaj yeem rov ua dua thiab ntws thaum cua sov, thiab tuaj yeem ua kom khov thiab tsim thaum txias. Thermoplastic plastics muaj qhov zoo ntawm kev ua haujlwm zoo, rov ua dua tshiab, thiab tus nqi qis, tab sis lawv kuj muaj qhov tsis zoo xws li cov cua sov tsis zoo, yooj yim deformation, thiab kev laus yooj yim. Cov khoom siv thermoplastic feem ntau suav nrog polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), polyamide (PA), polycarbonate (PC), polyethylene terephthalate (PET), thiab lwm yam.
- Thermosetting plastics: yog hais txog cov yas uas tuaj yeem ua tsis tau cov tshuaj tiv thaiv kab mob sib kis thaum cua sov, tab sis yuav tsis muag los yog ntws thaum txias. Thermosetting plastics muaj qhov zoo xws li cov cua sov zoo, qhov ruaj khov, thiab lub zog siab, tab sis kuj muaj qhov tsis zoo xws li kev ua haujlwm tsis zoo, tsis siv neeg rov ua dua tshiab, thiab tus nqi siab. Feem ntau siv cov thermosetting yas xws li phenolic resin (PF), urea-formaldehyde resin (UF), epoxy resin (EP), unsaturated polyester resin (UP), thiab lwm yam.
- Elastomers: hais txog cov yas uas muaj elasticity siab thiab thim rov qab deformation ntawm chav tsev kub. Elastomers muaj qhov zoo xws li softness, zoo resilience, thiab zoo kub tsis kam, tab sis kuj muaj qhov tsis zoo xws li roj tsis zoo thiab tsis zoo kub tsis kam. Feem ntau siv elastomers suav nrog cov roj hmab ntuj (NR), styrene-butadiene roj hmab (SBR), chloroprene roj hmab (CR), silicone roj hmab (SI), amino roj hmab (NBR), thiab lwm yam.
- Engineering plastics: yog hais txog cov yas uas muaj cov khoom zoo tshaj plaws uas tuaj yeem hloov cov hlau lossis lwm yam khoom siv ib txwm siv thiab siv rau hauv cov xwm txheej hnyav xws li kub siab, siab, thiab lub zog siab. Engineering plastics muaj qhov zoo xws li lub teeb yuag, siab zog, corrosion kuj, thiab zoo rwb thaiv tsev, tab sis lawv kuj muaj qhov tsis zoo xws li tus nqi siab thiab kev ua haujlwm nyuaj. Feem ntau siv engineering plastics suav nrog polyimide (PI), polyphenylene sulfide (PPS), polyetheretherketone (PEEK)
