HDPE yog polyethylene high-density thaum PP yog polypropyleneYog li qhov sib txawv tseem ceeb ntawm HDPE thiab PP yog HDPE yog tsim nrog ethylene monomer whereas PP yog tsim nrog propylene monomer. Polymers yog macromolecules tsim los ntawm ntau lub me me molecules hu ua monomers.
Qhov twg zoo dua HDPE lossis polypropylene?
Density yog qhov tseem ceeb uas sib txawv HDPE los ntawm PP. Vim tias HDPE muaj qhov ntom ntom, nws tuaj yeem nruj dua. Ua tsaug rau nws qhov qis dua, txawm li cas los xij, PP, tuaj yeem siv thaum molding qhov chaw nrog qhov hnyav. Zoo li HDPE, Polypropylene muaj cov tshuaj tiv thaiv zoo.
Qhov txawv ntawm PP thiab PE yog dab tsi?
Polyethylene (PE) yog tawv tsis tau lub teeb, nrog zoo tiv thaiv kev cuam tshuam thiab puas. Ntawm qhov tod tes, Polypropylene yog nyuaj thiab tuaj yeem siv rau kev siv tshuab thiab cov qauv siv. … Polypropylene yog qhov tawv thiab muaj tshuaj lom neeg ntau dua thiab khawb-resistant, thaum tseem tawv heev.
Cov khoom siv twg zoo ib yam li polypropylene?
Txawm hais tias polypropylene yog nplua ntawm qib molecular, nws muaj coefficient ntawm kev sib txhuam - yog vim li cas acetal, nylon, lossis PTFE yuav siv los hloov.
YKoj puas tuaj yeem sib xyaw HDPE thiab PP?
Cov txiaj ntsig DSC thiab XRD qhia tias PP thiab HDPE tsis sib xws, thiab kev sib xyaw ntawm HDPE tsis cuam tshuam nrog cov qauv crystalline thiab ruaj khov ntawm PP.
