MBS (Methylmetharylate-Butadiene-Styrene), feem ntau hu ua MBS impact modifier lossis MBS resin, yog ib yam tshiab ntawm cov khoom siv polymer synthesized raws li particle tsim lub tswv yim. Nws yog npaj los ntawm cov tshuaj pleev plhu grafting polymerization ntawm methyl methacrylate (M), butadiene (B) thiab styrene (S). Cov tub ntxhais yog cov roj hmab kheej kheej kheej kheej nrog txoj kab uas hla ntawm 10 nm ~ 100 hli, thiab sab nraud yog lub plhaub uas muaj styrene thiab methyl methacrylate. Vim tias qhov tsis sib haum xeeb ntawm methyl methacrylate thiab polyvinyl chloride (PVC) zoo ib yam, Nws ua raws li cov nplaum sib txuas ntawm PVC resin thiab cov khoom siv roj hmab, cov ntaub ntawv homogeneous theem nyob rau hauv cov txheej txheem ntawm kev ua thiab sib tov nrog PVC, thiab muab cov khoom zoo heev cuam tshuam.
MBS cuam tshuam hloov pauv zoo ib yam li lwm hom kev hloov kho. Nws yog PVC / MBS Blend composite system tsim los ntawm kev sib xyaw nrog PVC. Nws muaj cov huab cua zoo heev, kev cuam tshuam tsis kam, kev laus ua haujlwm, xim, toughness thiab ua fluidity. Nws yog dav siv hauv PVC tawv daim ntawv, yeeb nkab, phaj, sab hauv kho kom zoo nkauj board, zaj duab xis, lub raj mis khoom thiab ntau yam khoom profile.
Thaum 5 feem pua - 10 feem pua MBS resin ntxiv rau PVC, qhov cuam tshuam lub zog ntawm cov khoom tuaj yeem nce ntxiv los ntawm 4-15 zaug. Nyob rau tib lub sijhawm, qhov txias ua haujlwm thiab kev ua haujlwm fluidity ntawm cov khoom tuaj yeem txhim kho. Nws qhov refractive index zoo ib yam li PVC. Siv MBS raws li PVC cuam tshuam hloov pauv yuav tsis cuam tshuam rau qhov pom ntawm PVC. MBS yog cov khoom siv zoo tshaj plaws los txhim kho qhov cuam tshuam ntawm PVC thiab tsim cov khoom pob tshab. Yuav luag tag nrho cov khoom pob tshab PVC siv nws los ua kev hloov pauv. Feem ntau hais lus, MBS muaj qhov tsim nyog sib raug zoo thaum sib xyaw nrog PVC, thiab txhim kho kev ruaj ntseg ntawm kev sib xyaw. Lub iav hloov pauv kub ntawm MBS yog qhov qis, yog li nws tuaj yeem txhim kho qhov cuam tshuam ntawm PVC nyob rau hauv ib qho kev txwv kub. Txhim kho qhov tawv thiab kev ua tiav ntawm PVC yog lwm yam khoom tseem ceeb ntawm MBS, uas yog, kev sib txhuam ntxiv los txhawb PVC particle disintegration thiab ntxiv gelation, txo lub sij hawm melting, txo cov khoom nyob rau lub sij hawm, tiv thaiv decomposition, thiab thaum kawg txhim kho kev ua tau zoo.
Daim ntawv thov teb ntawm MBS resin tau nthuav dav, thiab nws tau ntxiv dag zog ua ib qho kev hloov kho tshwj xeeb ntawm engineering plastics. Peb cov khoom GM series yog cov khoom siv ntxiv dag zog tshwj xeeb tsim rau engineering plastics, uas tuaj yeem txhim kho qhov kub thiab txias zog thiab kev ua haujlwm ntawm engineering plastics. Lawv tau siv dav hauv engineering plastics PC / ABS.
Raws li kev siv sib txawv, peb cov khoom MBS tam sim no feem ntau muaj peb lub lag luam: pob tshab PVC cov khoom, xws li calendered film, ntawv, thiab lwm yam; Cov khoom tsis yog pob tshab xws li CPVC kav thiab fittings; Thiab engineering plastics ABS / PC khoom.
