Thaum nws los txog rau cov ntaub ntawv yas txhaj tshuaj molding, muaj ntau ntau txoj kev xaiv los ntawm, txhua tus nrog nws cov yam ntxwv tshwj xeeb thiab siv tau. Cov nram qab no yog kaum cov khoom siv yas txhaj tshuaj molding uas ua tau zoo hauv lawv cov haujlwm.
Polypropylene (PP): Polypropylene yog cov khoom siv tshuaj molding uas muaj tshuaj lom neeg zoo, tsis tshua muaj nqi, thiab cov khoom siv zoo. Nws yog dav siv hauv kev lag luam xws li ntim khoom noj, khoom siv kho mob, thiab cov khoom siv tsheb.
Polyethylene (PE): Polyethylene yog lwm cov khoom siv tshuaj molding, muab faib ua ob hom: high-density polyethylene (HDPE) thiab low-density polyethylene (LDPE). HDPE muaj qhov zoo rigidity thiab cuam tshuam tsis kam, thiab haum rau cov teb xws li cov tso tsheb hlau luam, cov kav dej, thiab cov khoom siv hauv tsev. LDPE muaj qhov yooj yooj yim thiab plasticity, haum rau cov teb xws li zaj duab xis, ntim, thiab hnab.
Polyvinyl chloride (PVC): PVC yog ib hom yas uas muaj tshuaj lom neeg thiab huab cua tsis kam. Nws yog dav siv nyob rau hauv teb xws li kev tsim kho, xov hlau thiab cables, thiab cov khoom siv kho mob.
Polystyrene (PS): Polystyrene yog cov yas uas yooj yim rau kev ua thiab cov duab, thiab muaj ob hom: polystyrene tsis tu ncua (GPPS) thiab siab cuam tshuam polystyrene (HIPS). GPPS feem ntau yog siv rau cov pob tshab thiab cov khoom siv hluav taws xob, thaum HIPS yog siv rau cov ntawv thov uas yuav tsum muaj lub zog muaj zog.
Polyamide (PA): Polyamide, tseem hu ua nylon, yog cov khoom siv tshuaj molding nrog lub zog zoo thiab hnav tsis kam. Nws yog dav siv nyob rau hauv teb xws li mechanical qhov chaw, automotive Cheebtsam, thiab textiles.
Polycarbonate (PC): Polycarbonate yog cov yas pob tshab uas muaj kev cuam tshuam zoo heev thiab ua haujlwm kub. Nws yog feem ntau siv nyob rau hauv cov teb xws li optical Cheebtsam, automotive teeb pom kev zoo fixtures, thiab hluav taws xob khoom casings.
Polyester (PET): polyester yog cov khoom siv tshuaj molding nrog cov khoom zoo heev thiab tshuaj lom neeg ruaj khov. Nws yog feem ntau siv hauv cov teb xws li ntim khoom noj, lub raj mis, thiab fibers. PET kuj yog cov yas rov ua dua tshiab.
Polymethyl methacrylate (PMMA): PMMA yog cov yas pob tshab zoo ib yam li iav. Nws muaj qhov ua tau zoo kho qhov muag thiab kev tiv thaiv huab cua, thiab feem ntau yog siv rau hauv thaj chaw xws li qhov muag qhov muag, kho kom zoo nkauj, thiab cov khoom siv tsheb.
Polyphenylene sulfide (PES): PES yog cov khoom siv txhaj tshuaj molding nrog cov khoom siv hluav taws xob zoo thiab hluav taws xob rwb thaiv tsev. Nws yog dav siv hauv kev lag luam xws li cov khoom siv hluav taws xob thiab hluav taws xob, cov khoom siv tsheb, thiab kev siv tshuab.
Polyether ether ketone (PEEK): PEEK yog cov khoom siv hluav taws xob ua haujlwm siab nrog cov cua sov zoo, tshuaj lom neeg ruaj khov thiab cov khoom siv kho tshuab. Nws yog feem ntau siv rau hauv kev xav tau siab xws li aerospace, cov cuab yeej kho mob, thiab kev lag luam tsheb.
Qhov no tsuas yog ib feem me me ntawm kev txhaj tshuaj molding cov ntaub ntawv, thiab muaj ntau lwm yam ntaub ntawv muaj nyob rau hauv kev ua lag luam, txhua tus nrog nws cov tshwj xeeb zoo thiab daim ntawv thov ntau yam. Xaiv cov khoom tsim nyog txhaj tshuaj molding nyob ntawm qhov yuav tsum tau muaj, pob nyiaj siv, thiab ib puag ncig ntawm cov khoom kawg.
