Lub ntsiab nta:
Feem ntau cov plastics yog lub teeb, sib txeeb thiab tsis xeb;
Tej yam yuav ua haujlwm zoo
Muaj kev pom zoo thiab hnav ua haujlwm;
Kev rwb thaiv kom zoo thiab thermal conductivity tsawg;
General moldability, colorability, cov nqi qis;
Feem ntau cov plastics tsis muaj kev kub hnyiab, siab thermal expansion npaum li cas, thiab lawv yuav yooj yim rau kev hlawv.
Kev ruaj ntseg tsis zoo, yooj yim deformed;
Feem ntau cov plastics muaj cov pluag tsis haum, ua pa tsis tshua muaj qhov sov, thiab yuav muaj hnub nyoog;
Qee cov khoom yas tau yooj yim nyob hauv cov kua kuab tshuaj.
Plastics yuav faib ua ob pawg, thermosetting thiab thermoplastic. Tus qub tsis tuaj yeem hloov kho thiab tom kawg yuav rov qab ua dua. Thermal plasticity muaj lub cev loj loj, feem ntau yog 50% txog 500%. Cov quab yuam tsis hloov kiag li ntawm qhov txawv elongations.
Cov khoom sib txawv ntawm cov khoom siv txiav txim siab siv lawv cov kev lag luam. Nrog rau kev nce qib ntawm technology, kev hloov kho ntawm plastics tsis tau nres. Nws vam tias yav tom ntej, cov khoom siv yuav siv ntau dua tom qab kev hloov kho, thiab lawv tuaj yeem hloov hlau thiab lwm yam khoom thiab tsis tuaj yeem hloov qhov chaw nyob.
