Dab tsi yog qhov feem ntau txhaj tshuaj molding yas?

Polyethylene (PE) yog ib hom kev txhaj tshuaj molding yas. Nws muaj cov tshuaj lom neeg ruaj khov zoo, hluav taws xob rwb thaiv tsev, thiab kev ua haujlwm zoo, thiab tus nqi kuj tsawg. Polyethylene txhaj tshuaj molded cov khoom muaj kev cuam tshuam zoo heev, hnav tsis kam, thiab corrosion kuj, ua rau lawv siv dav hauv ntim, ntim, kav dej, thiab lwm yam. Txawm li cas los xij, polyethylene muaj cov cua sov tsis zoo thiab muaj qhov ua rau deformation ntawm qhov kub thiab txias, uas rau qee qhov txwv nws daim ntawv thov nyob rau hauv qhov kub thiab txias.
Thib ob, polypropylene (PP) kuj yog ib qho ntawm cov yas txhaj tshuaj molding. Polypropylene muaj cov cua kub tsis kam, txhua yam muaj zog, thiab hnav tsis kam, nrog rau kev ua haujlwm zoo thiab rov ua dua tshiab. Qhov no tau ua rau polypropylene txhaj tshuaj molded khoom siv dav hauv cov teb xws li tsheb, hluav taws xob, thiab kev kho mob. Tshwj xeeb tshaj yog nyob rau hauv kev lag luam automotive, polypropylene yog dav siv nyob rau hauv kev tsim cov khoom siv tsheb vim nws lub teeb yuag, siab zog, thiab corrosion kuj. Txawm li cas los xij, polypropylene muaj qhov tsis zoo rau qhov txias txias thiab nws yooj yim rau brittleness ntawm qhov kub thiab txias, yuav tsum tau xyuam xim rau kev siv ib puag ncig.
Ib zaug ntxiv, polyvinyl chloride (PVC) yog lwm hom kev txhaj tshuaj molding yas. PVC muaj kev ruaj ntseg zoo, rwb thaiv tsev thiab nplaim hluav taws, nrog rau kev ua haujlwm zoo thiab zoo nkauj. PVC txhaj tshuaj molded khoom yog dav siv nyob rau hauv teb xws li kev tsim kho, xov hlau thiab cables, ntim, thiab lwm yam. Txawm li cas los xij, PVC tuaj yeem tsim cov khoom tsis zoo thaum tsim khoom thiab siv, ua rau muaj kuab paug ib puag ncig, yog li nws daim ntawv thov raug txwv rau qee yam.
Tsis tas li ntawd, polystyrene (PS) thiab acrylonitrile butadiene styrene copolymer (ABS) kuj yog cov yas txhaj tshuaj molding. Polystyrene muaj cov pob tshab zoo, glossiness, thiab cov khoom ua haujlwm, thiab feem ntau yog siv rau hauv kev tsim cov khoom siv pov tseg, cov khoom ua si, thiab lwm yam. Txawm li cas los xij, qhov tsis zoo ntawm cov cua sov thiab kev cuam tshuam ntawm polystyrene txwv nws cov ntawv thov ntau yam. ABS muab cov tshuaj tiv thaiv corrosion ntawm acrylonitrile, lub zog ntawm butadiene, thiab kev ua haujlwm ntawm styrene, nthuav tawm kev ua haujlwm zoo heev. ABS txhaj tshuaj molded cov khoom tau siv dav hauv kev lag luam xws li hluav taws xob, khoom siv hauv tsev, thiab tsheb, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas yuav tsum tau muaj zog thiab zoo nkauj.
Thaum kawg, nylon (PA) thiab polycarbonate (PC) kuj yog cov tswv cuab tseem ceeb hauv kev txhaj tshuaj molding yas. Nylon muaj lub zog txhua yam, hnav tsis kam, thiab kub tsis kam, thiab feem ntau yog siv rau hauv kev tsim khoom ntawm cov khoom siv xws li cov iav thiab cov kabmob. Polycarbonate yog lub npe hu rau nws lub siab pob tshab, siab zog, thiab zoo heev tshav kub tsis kam, thiab yog dav siv nyob rau hauv optical lo ntsiab muag, hluav taws xob cov ntxaij vab tshaus, thiab lwm yam teb. Txawm li cas los xij, tus nqi ntawm nylon thiab polycarbonate yog qhov siab, uas rau qee qhov txwv lawv qhov chaw.
Hauv cov ntsiab lus, polyethylene, polypropylene, polyvinyl chloride, polystyrene, acrylonitrile butadiene styrene copolymer, nylon, thiab polycarbonate yog cov yas txhaj tshuaj molding. Lawv txhua tus muaj qhov ua tau zoo thiab qhov zoo thiab qhov tsis zoo, haum rau ntau daim ntawv thov. Thaum xaiv cov yas 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 tus nqi los xaiv cov khoom yas uas haum tshaj plaws. Nrog rau kev nce qib ntawm kev siv tshuab thiab kev hloov pauv hauv kev ua lag luam, ntau yam tshiab ntawm kev txhaj tshuaj molding yas tuaj yeem tshwm sim yav tom ntej, coj ntau txoj hauv kev rau kev txhaj tshuaj molding kev lag luam.
