Ntug ultra sonic kaw welded foldable Hoobkas nqi tiv thaiv cog PP Corrugated Corflute Tsob Ntoo Guard

Cov khoom siv PP hom copolymer muaj qhov kub qis dua thermal distortion (100 ° C), tsis tshua muaj pob tshab, tsis tshua muaj gloss, tsis tshua muaj rigidity, tab sis muaj zog cuam tshuam ntau dua. Lub zog ntawm PP nce nrog rau cov ethylene nce. Qhov kub Vicat softening ntawm PP yog 150 ° C. Vim muaj qib siab ntawm crystallinity, cov khoom siv no muaj qhov zoo ntawm qhov chaw thiab cov khoom tiv thaiv khawb. PP tsis muaj teeb meem kev ntxhov siab ib puag ncig. Feem ntau, PP raug hloov kho los ntawm kev ntxiv cov iav fibers, cov hlau ntxiv lossis cov roj hmab thermoplastic. Tus nqi ntws MFR ntawm PP yog txij li 1 txog 40. Cov khoom siv PP nrog MFR qis muaj kev tiv thaiv kev cuam tshuam zoo dua tab sis qis dua ductility. Rau tib yam khoom siv MFR, lub zog ntawm hom copolymer siab dua li ntawm hom homopolymer. Vim muaj crystallization, tus nqi shrinkage ntawm PP yog siab heev, feem ntau 1.8 ~ 2.5%. Thiab qhov sib xws ntawm kev shrinkage zoo dua li ntawm PE-HD thiab lwm yam khoom siv. Ntxiv 30% iav additive tuaj yeem txo qhov shrinkage mus rau 0.7%.
