High Impact Polystyrene, feem ntau hu ua HIPS, yog cov khoom siv thermoplastic ua los ntawm elastomer-hloov polystyrene. Cov txheej txheem ob-theem, uas muaj cov roj hmab theem thiab ib ntus polystyrene tsis tu ncua, tau hloov zuj zus mus rau hauv cov khoom tseem ceeb polymer thoob ntiaj teb, thiab cov khoom siv ntau yam no muaj ntau yam kev cuam tshuam thiab kev ua haujlwm, muab ntau yam kev siv, xws li siv hauv tsheb, khoom siv, khoom siv hluav taws xob, rooj tog zaum, khoom siv hauv tsev, kev sib txuas lus, hluav taws xob, khoos phis tawj, pov tseg, tshuaj, ntim khoom, thiab kev lag luam ua si.
Vim tias nws yooj yim ntawm kev tsim khoom thiab tus nqi qis, HIPS tau siv dav hauv ntau yam khoom siv thiab kev lag luam. Kev lag luam loj thiab kev lag luam muaj xws li ntim khoom, cov khoom siv pov tseg, cov khoom siv thiab cov khoom siv hauv tsev, cov khoom ua si thiab cov khoom ua si, cov khoom siv hauv tsev thiab cov khoom siv zoo nkauj.Qhov loj tshaj plaws ib daim ntawv thov ntawm HIPS yog ntim, tshwj xeeb tshaj yog nyob rau hauv kev lag luam khoom noj khoom haus, qhov twg nws tau noj ntau tshaj 30% ntawm ntiaj teb cov pejxeem.
High cuam tshuam polystyrene nrog cov yam ntxwv hauv qab no:
1. Kev cuam tshuam resistant polystyrene yog cov thermoplastic cob;
2. Tsis muaj ntxhiab, tsis qab, cov khoom tsis zoo nrog kev ruaj ntseg zoo tom qab molding;
3. Zoo heev dielectric rwb thaiv tsev;
4. Cov khoom tsis zoo thiab tsis tshua muaj dej nqus;
5. Nws muaj gloss zoo thiab yooj yim rau xim.
Raws li kev ua tau zoo ntawm HIPS, ntau cov txheej txheem siv HIPS los hloov ABS, yog li hloov HIPS tau ua kom pom tseeb ntawm kev lag luam, uas yuav tsum ua li cas txhawm rau txhim kho kev ua tau zoo thiab qhov zoo ntawm HIPS?
1, kev xaiv raw khoom
Hauv cov txheej txheem xaiv cov khoom siv raw, peb yuav tsum nrhiav kev sib xyaw ua ke uas sib npaug ntawm qhov toughness thiab gloss ntawm HIPS (High Impact Polystyrene). Ntawm lawv, roj hmab-hloov polystyrene yog ib qho kev xaiv zoo, uas tuaj yeem txhim kho qhov tawv tawv ntawm HIPS thaum tuav nws cov gloss. Tsis tas li ntawd, cov txiaj ntsig zoo sib xws tuaj yeem ua tiav los ntawm kev siv graft-hloov polystyrene.
2 、 Optimization ntawm kev siv tshuab
Kev ua tau zoo thiab kev ua haujlwm ntawm HIPS tuaj yeem txhim kho los ntawm kev tswj cov txheej txheem kev ua haujlwm. Piv txwv li, qhov ua kom kub ua tau tuaj yeem txo qhov melting point ntawm cov khoom, yog li txhim kho nws cov toughness. Nyob rau tib lub sijhawm, qhov tsim nyog siab thiab kev ntxhov siab tuaj yeem ua rau cov khoom siv kom yaj ntau yam sib xws, yog li txhim kho cov khoom gloss. Tsis tas li ntawd, kev siv nanocomposite li technology kuj tseem tuaj yeem txhim kho qhov toughness thiab gloss ntawm HIPS.
3, kev hloov kho copolymerization
Kev hloov pauv ntawm copolymerization tuaj yeem hloov cov qauv tshuaj ntawm cov polymer, yog li hloov nws cov kev ua tau zoo. Thaum granulating HIPS, ntxivsilicone additivesnyob rau hauv kev faib ua feem los txhim kho kev ua tau zoo thiab nto thaj chaw ntawm HIPS.
SILIKE Silicone Masterbatch LYSI-410yog pelletized formulation nrog 50% ultra siab molecular hnyav siloxane polymer dispersed nyob rau hauv High impact polystyrene (HIPS). Nws yog dav siv los ua cov khoom siv tau zoo rau PS tau tshaj cov khoom siv los txhim kho cov khoom ua haujlwm thiab qhov chaw zoo, xws li cov peev txheej zoo dua, pwm filling & tso tawm, tsawg dua extruder torque, qis coefficient ntawm kev sib txhuam, ntau dua mar thiab puas.
SILIKE LYSI series silicone masterbatchtej zaum yuav ua tau zoo ib yam li cov cab cab uas lawv ua raws. Nws tuaj yeem siv rau hauv cov txheej txheem melting classical zoo li Ib leeg / Twin ntsia hlau extruder, txhaj tshuaj molding. Lub cev sib xyaw nrog nkauj xwb polymer pellets raug pom zoo.
Thaum ntxivSILIKE Silicone Masterbatch LYSI-410rau polyethylene los yog cov thermoplastic zoo sib xws ntawm 0.2 mus rau 1%, kev txhim kho thiab kev khiav ntawm cov resin yuav tsum, nrog rau cov pwm zoo dua, tsawg dua extruder torque, lubricants sab hauv, pwm tso tawm thiab nrawm dua; Nyob rau theem siab ntxiv, 2 ~ 5%, kev txhim kho saum npoo yuav tsum tau ua, nrog rau lubricity, plam, qis coefficient ntawm kev sib txhuam thiab ntau dua mar / khawb thiab puas.
Chengdu Silike Technology Co., Ltd yog cov chaw tsim khoom thiab cov khoom siv silicone, uas tau mob siab rau R & D ntawm kev sib xyaw ntawm Silicone nrog cov thermoplastics rau 20+ xyoo, cov khoom suav nrog tab sis tsis txwv rauSilicone masterbatch,Silicone hmoov,Anti-scratch masterbatch,Super-slip Masterbatch,Anti-abrasion masterbatch,Anti-Squeaking masterbatch,Silicone ciabthiabSilicone-Thermoplastic Vulcanizate (Si-TPV), for more details and test data, please feel free to contact Ms.Amy Wang Email: amy.wang@silike.cn.
