Qhov txawv ntawm PP Yas thiab PE Yas
PP thiab PE yog ob qho khoom siv yas, tab sis lawv txawv heev hauv lawv daim ntawv thov. Cov lus hauv qab no yuav qhia txog qhov sib txawv ntawm ob yam khoom no.
| Tshuaj Npe Tshuaj | Polypropylene | polyethylene |
| qauv | Tsis muaj Branching Chain Structure | Branched Chain Structure |
| ceev | 0.89-0.91g / Cm³ | 0.93-0.97g / Cm³ |
| Melting Point | 160-170 ℃ | 120-135 ℃ |
| Kub ua hauj | Kev kub siab ua haujlwm zoo, tuaj yeem tiv taus ntau dua 100 ℃ siab kub | Kev kub ntxhov siab yog qhov tsis zoo, feem ntau tuaj yeem tiv taus 70-80 ℃ siab |
| yooj Yim | High Hardness, Tab sis tsis zoo Flexibility | Zoo Flexibility, tsis yooj yim tawg |
Lub npe tshuaj, qauv, ntom, melting point, tshav kub tsis kam, thiab toughness ntawm PP thiab PE sib txawv heev raws li pom los ntawm cov lus hais saum toj no. Cov kev sib txawv no txiav txim siab lawv cov kev siv sib txawv.
Vim nws qhov siab hardness, tsis zoo toughness, zoo heev kub tsis kam, thiab zoo rwb thaiv tsev ntawm lwm yam ntxwv, PP yog feem ntau ua hauj lwm nyob rau hauv zus tau tej cov yas thawv, yas nruas, nws pib qhov chaw, hluav taws xob accessories thiab lwm yam. Ntawm qhov tod tes, PE pom Kev siv dav hauv kev tsim cov kav dej, cov khoom siv hluav taws xob cable, thiab cov hnab ntim khoom noj vim nws qhov kev qhuas zoo, hnav tsis kam, softness, thiab kub tsis kam.
Cov tsos ntawm PP thiab PE tej zaum yuav zoo sib xws, tab sis lawv cov yam ntxwv kev ua tau zoo sib txawv heev. Yog li, kev xaiv cov ntawv thov yuav tsum ua raws li cov khoom siv tshwj xeeb.
