Polypropylene yog qhov hnyav. Lawv muaj siab tiv thaiv tawg, acids, organic solvents thiab electrolytes. Lawv kuj muaj siab melting point thiab gooddielectric zog thiab yog non-toxic. Polypropylene isstiffer thiab resistant rau tshuaj thiab organic solvents piv rau topolyethylene.
Tsis tas li ntawd, polyethylene puas muaj cov ntsiab lus melting siab?
Rau cov khoom lag luam qib nruab nrab- thiab siab - ntom polyethylene tus melting point yog Feem ntau nyob rau hauv thaj tsam ntawm 120 txog 180 ° C (248 txog 356 ° F). Cov melting point rau qhov nruab nrab, kev lag luam, tsawg-qhov ceev polyethylene yog Feem ntau 105 txog 115 ° C (221 txog 239 ° F). Cov no kub sib txawv heev nrog rau hom polyethylene.
Ib sab saum toj no, qhov kev pabcuam siab tshaj plaws ntawm polypropylene yog dab tsi? Cov siab tshaj pom zoo kev khiav hauj lwm kub rau polypropylene yog 180°F (82.2°C). Tom qab no kub , qhov kev ua tau zoo ntawm cov khoom siv yuav raug cuam tshuam.
Tom qab, lo lus nug yog, dab tsi yog qhov melting point ntawm polypropylene?
320 ° F (160 ° C)
Yuav ua li cas thaum polypropylene rhuab?
Cov ntaub ntawv thermoplastic ua kua ntawm lawv qhov chaw melting (kwv yees li 130 degrees Celsius nyob rau hauv rooj plaub ntawm polypropylene ). Ib qho txiaj ntsig tseem ceeb ntawm cov thermoplastics yog tias lawv tuaj yeem ua tau cua sov mus rau lawv meltingpoint, txias, thiab reheated dua tsis muaj degradation tseem ceeb.
