Cov khoom siv tshuaj lom neeg: Polyethylene tiv taus ntau yam organic solvents, thiab tiv taus ntau yam acid thiab alkali corrosion, tab sis nws tsis tiv taus oxidizing acids, xws li nitric acid. Polyethylene yuav oxidized nyob rau hauv ib puag ncig oxidizing.
Lub cev muaj zog: Polyethylene tuaj yeem suav tias yog pob tshab hauv lub xeev ntawm zaj duab xis, tab sis thaum nws muaj nyob rau hauv cov duab thaiv, vim muaj cov muaju ntau hauv, nws yuav dhau los ua lub teeb tawg thiab ua opaque. Lub degree ntawm crystallization ntawm polyethylene yog cuam tshuam los ntawm tus naj npawb ntawm cov ceg. Qhov ntau ceg, qhov nyuaj nws yog crystallize. Lub melting kub ntawm polyethylene crystals kuj cuam tshuam los ntawm tus naj npawb ntawm cov ceg chains, uas nyob rau ntawm 90 degrees Celsius mus rau 130 degrees Celsius. Cov ceg chains ntau dua, qhov kub ntawm melting qis dua. Polyethylene ib leeg muaju feem ntau tuaj yeem npaj tau los ntawm kev ua kom lub siab ntom ntom polyethylene hauv xylene hauv ib puag ncig siab dua 130 degrees Celsius.
