Dab tsi yog Qhov Kub Kub Ua Haujlwm Ntawm PE

tuaj yeem tiv taus 80 txog 90 degrees. Tab sis Pe tau muab faib ua peb cov ntaub ntawv: LDPE, HDPE thiab LLDPE, cov khoom sib txawv muaj qhov sib txawv ntawm qhov kub thiab txias. Piv txwv li, LDPE tuaj yeem tiv taus -60 txog 80 degrees, HDPE tuaj yeem tiv taus -40 txog 90 degrees, thiab LLDPE tuaj yeem tiv taus -40 txog 90 degrees. Ntawm lawv, LLDPE muaj kev hnav zoo, kua qaub thiab alkali tsis kam, thiab cov organic hnyav tsis kam, thiab tshwj xeeb tshaj yog tsim rau kev tsim cov yeeb yaj kiab. Cov yeeb yaj kiab uas tsim tawm yog nyias dua li LDPE, tab sis muaj zog dua.
