Xim Polypropylene Ntawv

Khoom taw qhia ntawm cov xim polypropylene ntawv

Cov ntawv xim polypropylene muaj l ower thermal distortion kub (100 C), tsis tshua muaj pob tshab, tsis tshua muaj siab thiab tsis tshua muaj txhav, tab sis muaj cov khoom ua kom muaj zog. Lub zog ntawm PP nce nrog qhov nce ntawm ethylene cov ntsiab lus. Lub Vicat softening ntsuas kub ntawm PP yog 150 C. Vim tias nws lub siab kub khov, qhov chaw nruj thiab khawb tsis kam ntawm cov khoom no zoo heev. Tsis muaj ib qho kev nyuab siab ib puag ncig tawg hauv PP. Feem ntau, PP hloov kho los ntawm kev ntxiv iav fiber ntau, hlau txuas ntxiv lossis roj hmab thermoplastic. MFR ntawm PP li ntawm 1 txog 40. Tsawg MFR PP khoom muaj qhov cuam tshuam zoo dua tab sis qis dua ductility. Rau tib yam MFR khoom, lub zog ntawm copolymer hom yog siab dua li ntawm homopolymer hom. Raws li qhov tshwm sim ntawm crystallization, lub shrinkage ntawm PP yog qhov siab heev, feem ntau 1.8-2.5%. Thiab cov directional uniformity ntawm shrinkage tus nqi yog zoo tshaj li ntawm PE-HD thiab lwm yam ntaub ntawv. Lub ntsws yuav txo tau kom 0.7% los ntawm kev ntxiv 30% iav ntxiv. Homopolymer thiab copolymer PP cov ntaub ntawv muaj hygroscopicity zoo, acid-puag xeb ua hauj thiab solubility tsis kam. Txawm li cas los xij, nws tsis muaj qhov tsis kam tiv thaiv cov tshuaj uas muaj ntxhiab hydrocarbons (xws li benzene) thiab chlorinated hydrocarbons (carbon tetrachloride) cov kuab tshuaj. PP tsis yog antioxidant li PE li ntawm qhov kub.
