Yog hais tias qhov no suab paub, qhov teeb meem tiag tiag tsis yog dej khov - nws yog qis-notch impact resistance nyob rau hauv lub hnab lub polymer qauv.
3 qhov laj thawj zais koj lub hnab ntim PE tam sim no tsis muaj zog
Cov ntsiab lus siv ntau dhau - Tshaj 30% tshaj tawm -kev lag luam regrind tua elongation thaum so.
Tsis muaj cov tshuaj tiv thaiv -cov neeg ua haujlwm khov - Yog lawm, PE xav tau cov tshuaj ntxiv tshwj xeeb kom nyob twj ywm hauv qab -10℃.
Kev sib khi tsis sib haum - Lub foob hauv qab tsis muaj zog ua tsis tau ntev ua ntej zaj duab xis nws tus kheej.
Ntawm YingFei Pob, peb kev cai engineer PE hnab ntim dej khov siv peb - txheej co- txheej txheem extrusion:
Txheej txheej: Siab -gloss LDPE rau kev luam tawm
Nruab nrab txheej: mPE + EVA copolymer rau qhov yooj yim heev
Sab hauv: Khoom noj khoom haus- qib LLDPE rau kev tiv thaiv dej khov ncaj qha
Qhov tshwm sim? Cov hnab uas ncab es tsis txhob tawg - txawm tias poob ntawm 1 meter siab puv ntawm cov dej khov nab kuab.
