Cov lus qhia tseem ceeb: PP tuaj yeem raug cais raws li cov substrates sib txawv, hauv kev faib tawm tseem tuaj yeem sib txawv ntawm qhov sib txawv ntawm qhov sib txawv, thiab txawm tias raws li kev siv cov khoom siv ntxiv rau cov khoom siv los txiav txim siab txog kev siv cov specifications.Piv txwv li, hauv ib qho polymer, MFR: 12 lossis li ntawd tuaj yeem siv rau kev dav davcov khoom txhaj tshuaj, kuj tuaj yeem siv rau kev tsim cov fiber ntau ntau, thiab tuaj yeem tsim tshwj xeeb los muab cov khoom hnyav molecular faib los txhim kho cov txheej txheem rov qab ntawm fiber ntau. kom nce qhov qhib kom tau raws li qhov yuav tsum tau ua ntawmhnab yascov khoom.
1. Qib General (homopolymer)
Monopolymer, los yog homopolymer, yog cov khoom siv raw los ntawm cov ntshiab propylene yog polymerized.
2. cuam tshuam COPOLYMER
Thaum ib lub polymer ntxiv nrog ethylene propylene roj hmab, qhov cuam tshuam lub zog feem ntau yog nyob ntawm cov roj hmab cov ntsiab lus, thiab qhov txias kuj tseem nyob ntawm cov ntsiab lus ethylene.Different raw khoom manufacturers txheej txheem sib txawv, qhov siab tshaj plaws ethylene cov ntsiab lus kuj txawv.
3. High isotacites lossis HIGH CRYSTALINITY
Txo cov ntsiab lus ntawm cov qauv dislocation hauv PP polymer, cov txheeb ze nce ntawm cov qauv cov ntsiab lus tsis tu ncua, kuj txhim kho cov crystallinity.Nws tsuas yog txhim kho cov rigidity, thermal denaturation kub, deg hardness, khawb kuj thiab gloss ntawm raw cov ntaub ntawv. Tau kawg, qhov sib ntxiv ntawm nucleating tus neeg sawv cev tseem yuav pab txhawb kev txhim kho ntawm cov khoom saum toj no.
4. Random COPOLYMER
Randomized copolymerization yog propylene thiab ethylene copolymerization.Ethylene yog irregularly dispersed nyob rau hauv lub polymer, uas tsuas yog txo cov crystallinity ntawm lub polymer thiab txhim kho cov pob tshab.
5. Terpolymer
Yog ib qho kev txuas ntxiv ntawm random ntawm polymer, feem ntau muaj propylene ethylene (EPR) cov qib siab tshaj plaws ntawm 3.5%, tab sis kuj tseem muaj cov txheej txheem tuaj yeem ntxiv rau 5%, thiab cov ntsiab lus ethylene ntau dua hauv cov khoom muag muag, thermal deformation kub, softening. taw tes, qhov qis dua qhov kub thiab txias sealing, qee zaum txhawm rau txhawm rau nce cov ntsiab lus ethylene nrog kev pab ntawm butadiene los yog lwm yam khoom xyaw thib peb ua peb hom polymer, thiaj li ua tiav cov khoom ntiag tug saum toj no.
6. qib alloy
Kev sib xyaw ntawm cov khoom sib txawv ntawm cov khoom siv yas uas muaj qhov sib npaug siab tuaj yeem piav qhia raws li qib alloy.Piv txwv li, PP ntxiv nrog LDPE tuaj yeem txhim kho qhov muag muag thiab kev cuam tshuam lub zog, thiab tseem tuaj yeem txo cov caj dab thiab ua rau kom smoothness hauv kev ua haujlwm.Hauv molding, nws tseem tuaj yeem txo qhov poob ntawm cov khoom tshwm sim.PP ntxiv rau EPR ntxiv rau HDPE tuaj yeem tswj kev nruj, txo qhov tshwm sim ntawm qhov tshwm sim los ntawm cov ntsiab lus EPR siab, thiab txhim kho qhov cuam tshuam lub zog.
7. Kev sib xyaw ua ke
Kev sib xyaw ntawm cov khoom sib txawv
