Hauv cov txheej txheem ntawm lub tshuab nqus tsev molding, kev ua haujlwm zoo tshaj plaws ntawm kev hloov kho ntawm daim ntawv hloov polypropylene yog sib tov (20% - 30%) tsawg ntom polyethylene (PE).
Cov uas yuav tsum tau ua ntawm polypropylene rau molding kev ua haujlwm, pwm lub kaum sab xis: txiv neej pwm 20-3o (qib siab 5O), poj niam pwm 1o-3o (qib siab 5O); molding kub: daim ntawv kub 150-180 ℃, pwm kub 70 ℃ - 90 ℃; moulding shrinkage: txiv neej pwm 0.02-0.03mm / hli, poj niam pwm 0.03-0.04mm / hli. Raws li polypropylene daim ntawv muaj cov yam ntxwv ntawm cov khoom siv nplua nuj, tus nqi qis, tsis muaj tshuaj lom, tsis qab, zoo pob tshab, siab zog lub zog, thiab lwm yam, nws yog dav siv hauv cov zaub mov, tshuaj, khoom siv tshuab, txhua yam khoom siv txhua hnub thiab lwm yam khoom ntim. Tam sim no, polypropylene ntim khoom lag luam nyob rau hauv kev ua lag luam, ntxiv rau cov thawv noj su yooj yooj yim, shuipu, tais diav, tais, pickle thawv, txhua hom kev lag luam ntim cov thawv, khoom noj khoom haus yog yurt, tais, thiab lwm yam kuj tau nkag mus hauv lub khw muag khoom tau dav. Cov khoom lag luam polypropylene tuaj yeem raug rhaub hauv qhov cub microwave thiab sterilized ntawm 125 ℃, yog li lawv siv dav hauv kev npaj noj cov zaub mov ntim. Tsis tas li ntawd, polypropylene nqus tsev cov khoom lag luam tau maj mam siv rau hauv kev ua qoob loo nyob rau xyoo tsis ntev los no, xws li cov yub yub, txau khob , thiab lwm yam.
