Qhov ceev ntawm polyethylene ntawv sib txawv raws li ntau hom thiab cov txheej txheem. Raws li cov ntaub ntawv sau cia hauv kev tshawb nrhiav, lub ntsiab ntau yog raws li hauv qab no:
High-ceev polyethylene ntawv (HDPE)
Qhov chaw ceev ntau: {{{0}}}. 941 ~ 0.965 g /m³
Nov yog cov ntawv ntawm polyethylene, nrog siab crystallinity thiab kev kho tshuab zog, haum rau kev ua choj.
Qee ultra-siab molecular hnyav polyethylene (UHMWPE) muaj qhov qis dua me ntsis ntawm {}. 936 ~}. 964 g /}}. 936 ~.
Qhov ceev ntawm lwm hom kev polyethylene
Nruab Nrab-Ntawj Polyethylene (MDPE): 0. 916 ~}. 940 g / cm³
Tsawg-ceev polyethylene (ldpe): 0. 91 {}} ~ 0.925 g /m³
Cov hom no feem ntau siv rau ntim lossis zaj duab xis, thiab tsis tshua siv nyob rau hauv daim ntawv.
NCO TSEG: Kev siv ceev yuav hloov kho me ntsis vim yog cov txheej txheem sib ntxiv lossis cov txheej txheem ntau dua (moulding), tab sis qhov ceev ntawm cov nplooj ntawv HDPE yog feem ntau ruaj ntseg saum {. 94 g / cm³. 94 g / cm³. 94 g / cm³.
