1. Cov kav dej txias dej txias: Vim tias muaj cov yeeb nkab tshwj xeeb hauv cov yeeb nkab PE, uas yog, nano-cov kab mob PE yeeb nkab, nws qhov tseem ceeb tshaj plaws yog tias nws tuaj yeem ua tiav kev huv ntawm tus kheej- ntxuav, kom cov dej tuaj yeem ntws mus rau hauv cov yeeb nkab yam tsis muaj qhov ntsuas, tsis txhob haus cov dej qias neeg thib ob, tab sis nws yuav tsum tau muab sau tseg tias cov kav dej PE tsuas tuaj yeem tiv taus cov dej kub hauv qab 40 ° C, yog li lawv tsis tuaj yeem siv los ua cov kav dej kub, yog li lawv yog feem ntau yog siv los ua engineering cov kav dej.
2. Cov kav dej roj: PE kav dej muaj qhov sib txawv. Feem ntau hais lus, siab -PE kav dej muaj zog sealing zog, tej yam kub thiab txias kuj, thiab ruaj khov heev tshuaj. High- ntom polyethylene tsis yog- tshuaj lom thiab saj tsis zoo, thiab yuav tsis ua pa phem, yog li cuam tshuam rau kev nyab xeeb ntawm cov neeg siv, kom kev nyab xeeb kev thauj mus los ntawm cov roj tuaj yeem lav tau los ntawm qhov chaw.
3. Kev tiv thaiv casing: Ntxiv rau kev thauj khoom ncaj qha, cov kav dej PE kuj tseem siv tau los ua cov casings, uas tau siv dav hauv kev lag luam fais fab. PE yeeb nkab muaj cov rwb thaiv tsev siab heev, rigidity thiab toughness, uas tuaj yeem ua kom muaj kev nyab xeeb ntawm cov neeg siv, thiab nws kuj yooj yim heev rau txheej txheem.
