Cov yas twg tuaj yeem txhaj tshuaj molded?

1, Thermoplastic
Thermoplastic yog ib hom yas uas tuaj yeem rov ua kom sov, muag muag, txias, thiab tawv tawv hauv qee qhov kub thiab siab. Hom yas no tau dhau los ua cov khoom tseem ceeb rau kev txhaj tshuaj molding vim nws cov kev ua tau zoo heev thiab ntau yam kev siv. Feem ntau txhaj tshuaj molded cov ntaub ntawv thermoplastic muaj xws li:
Polyethylene (PE): Nrog zoo heev corrosion kuj, hluav taws xob rwb thaiv tsev thiab kev ua tau zoo, nws yog dav siv nyob rau hauv ntim, pipelines, cables thiab lwm yam teb.
Polypropylene (PP): Nws muaj lub zog siab, hardness, thiab kub tsis kam, thiab feem ntau yog siv rau hauv kev tsim cov ntim khoom, cov khoom siv tsheb, thiab cov khoom siv hauv tsev.
Polyvinyl chloride (PVC): Nrog zoo heev corrosion kuj, rwb thaiv tsev thiab nplaim retardancy, nws yog dav siv nyob rau hauv teb xws li kev tsim kho, xov hlau thiab cables, thiab cov khoom kho mob.
Polystyrene (PS): Nrog cov pob tshab zoo thiab cov khoom siv ua haujlwm, nws feem ntau yog siv rau hauv kev tsim cov khoom siv rooj tog, khoom ua si, thiab ntim khoom.
Nylon (PA): Nrog lub zog siab, hnav tsis kam, thiab nws tus kheej lubricating zog, nws yog dav siv hauv kev lag luam xws li tshuab, tsheb, thiab aviation.
Polycarbonate (PC): Nrog lub siab pob tshab thiab kub tsis kam, nws yog feem ntau siv hauv kev tsim cov khoom siv hluav taws xob, cov khoom siv teeb pom kev zoo, thiab cov lo ntsiab muag tiv thaiv.
2, Thermosetting yas
Thermosetting plastics undergone cov tshuaj tiv thaiv thaum lub sij hawm cua sov, tsim ib tug insoluble peb-dimensional network qauv. Txawm hais tias daim ntawv thov ntawm thermosetting plastics hauv kev txhaj tshuaj molding yog qhov txwv, kuj tseem muaj qee qhov tshwj xeeb thermosetting yas uas tuaj yeem ua tiav los ntawm cov txheej txheem tshwj xeeb txhaj tshuaj molding. Piv txwv li, thermosetting plastics xws li phenolic resins thiab epoxy resins muaj cov cua kub zoo heev, tshuaj tiv thaiv corrosion, thiab txhua yam muaj zog tom qab txhaj tshuaj molding, thiab feem ntau yog siv los tsim cov khoom lag luam thiab cov khoom lag luam.
3, Kev ceev faj thaum txhaj tshuaj molding txheej txheem
Kev xaiv cov ntaub ntawv yas: Thaum xaiv cov ntaub ntawv yas rau kev txhaj tshuaj molding, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo xav txog yam xws li cov khoom yuav tsum tau ua, kev siv ib puag ncig, thiab cov nqi ua haujlwm. Nyob rau tib lub sijhawm, nws tseem yuav tsum tau txiav txim siab txog qhov cuam tshuam ntawm cov khoom xws li cov khoom siv, flowability, thiab shrinkage tus nqi ntawm cov txheej txheem txhaj tshuaj molding.
Pwm tsim: Pwm yog ib qho ntawm cov cuab yeej tseem ceeb hauv kev txhaj tshuaj molding, thiab nws qhov kev tsim qauv ncaj qha cuam tshuam rau molding zoo thiab kev ua haujlwm ntawm cov khoom. Hauv kev tsim pwm, nws yuav tsum tau ua tib zoo xav txog yam xws li cov duab, qhov tseeb qhov tseeb, thiab qhov zoo ntawm cov khoom, thiab tsim kom muaj cov txheej txheem nchuav, cov tshuab tso pa, thiab cov tshuab ua kom txias.
Kev txhaj tshuaj molding txheej txheem tsis: Cov txheej txheem txhaj tshuaj molding tsis suav nrog kev txhaj tshuaj siab, txhaj tshuaj ceev, tuav lub sijhawm, pwm kub, thiab lwm yam. cov khoom tuaj yeem ua tiav cov pwm kab noj hniav thiab zam kev tsim ntawm cov khoom siv sab hauv.
