Puas yog PE cov kav dej xa dej ntshai tsam khov thaum lub caij ntuj no? PE cov yeeb nkab dej yog cov yeeb nkab yas, uas muaj cov ductility zoo dua li cov yeeb nkab hlau, uas yog hais tias, nyob rau hauv txias txias, lub peev xwm ntawm PE yeeb nkab los tiv thaiv cov dej khov o yuav muaj zog dua. Thaum lub caij ntuj no txias, kev saib xyuas ntawm PE cov kav dej yog qhov nyuaj dua. Rau kev yooj yim; PE yeeb nkab yog twb heev tawg-pov thawj nyob rau hauv cov yeeb nkab dej, vim hais tias nws yog hloov tau thiab stretchable, thiab nws yog yooj yim dua tawg yog tias cov yeeb nkab hlau hloov. PE cov yeeb nkab dej yuav tsum tau ua los ntawm cov khoom siv raw. Yog tias muaj cov khoom xa rov qab, nws yuav ua rau muaj kev cuam tshuam rau kev nthuav dav thiab kev cog lus ntawm cov khoom, uas yuav ua rau muaj kev nyab xeeb ntxiv. Theoretical kub ntawm PE yeeb nkab yog -40 degree c-40 degree c. Nws tsis puas los ntawm khov thaum siv sab nraum lub caij ntuj no. Lub toughness ntawm PE yeeb nkab yog zoo heev, txawm tias nws khov, nws yuav tsis puas. Qhov no yog qhov ua tau zoo ntawm PE yeeb nkab hauv qhov kub thiab txias tsis kam!
