Thermoplastic elastomer TPE / TPR cov khoom ua si, raws li SEBS thiab SBS, yog ib yam ntawm cov khoom siv polymer alloy nrog cov khoom siv yas dav dav tab sis cov khoom siv roj hmab.Lawv tau maj mam hloov cov yas yas thiab yog cov khoom siv zoo tshaj plaws rau cov khoom siv hauv Suav teb mus rau txawv teb chaws thiab xa tawm mus rau Tebchaws Europe, Amelikas, Australia, Nyiv thiab lwm qhov chaw.Nws muaj qhov zoo tactile elasticity, hloov tau yooj yim ntawm cov xim thiab hardness, kev tiv thaiv ib puag ncig, tsis muaj halogen, tsis muaj tshuaj lom thiab tsis qab;Los tiv thaiv plam thiab hnav tsis kam, dynamic qaug zog tsis kam, zoo heev poob siab, zoo UV tsis kam, ozone kuj thiab tshuaj tiv thaiv;Thaum ua tiav, nws tsis tas yuav qhuav thiab tuaj yeem rov ua dua.Nws tuaj yeem tsim los ntawm kev txhaj tshuaj molding, coated thiab sib koom nrog PP, PE, PS,ABS, PC, PA thiab lwm yam ntaub ntawv matrix, los yog tsim nyias.Hloov mos PVC thiab qee cov roj hmab silicone.
Cov ntxhiab tsw tawm los ntawm TPR cov khoom ua si yog vim muaj ntau yam, suav nrog lub tshuab, cov kauj ruam ua haujlwm, thiab kev ua haujlwm.Nws yog ib qho tseem ceeb uas TPR yuav muaj ntxhiab tsw, tab sis peb tuaj yeem txo qhov tsis hnov tsw kom tib neeg tsis txhob hnov qab, kom txhua tus tuaj yeem txais tau.Cov tuam txhab sib txawv muaj lawv tus kheej cov qauv, thiab cov ntxhiab tsw uas tsim los kuj txawv.Yuav kom ua tiav lub teeb tsis hnov tsw, nws yuav tsum muaj kev sib xyaw ua ke ntawm cov mis thiab cov txheej txheem kom muaj kev ua tau zoo.
1. Cov qauv
Feem ntau ntawm cov khoom ua si yog ua los ntawm TPR cov ntaub ntawv nrog SBS ua lub ntsiab substrate.SBS yuav tsum tau txiav txim siab hauv kev xaiv.SBS nws tus kheej muaj ntxhiab tsw thiab tsis hnov tsw ntawm cov kua nplaum yog loj dua li cov kua nplaum qhuav.Sim siv cov kua nplaum K los txhim kho cov tawv tawv, txo cov nqi ntawm PS, thiab xaiv cov roj nrog lub siab flash point ntawm paraffin wax.Cov roj dawb tsis huv kuj tseem yuav muaj qee yam tsis hnov tsw tom qab cua sov, yog li nws raug pom zoo kom xaiv cov khoom los ntawm cov tuam txhab tsis tu ncua.
2. Txheej txheem
TPR figurine khoom nrog SBS raws li lub ntsiab substrate yuav tsum nruj me ntsis tswj cov txheej txheem.Nws yog qhov zoo dua tsis txhob siv cov nruas sib xyaw ua ke thiab kab rov tav rau cov khoom sib xyaw, thiab lub sijhawm yuav tsum tsis txhob ntev dhau.Feem ntau hais lus, kev ua haujlwm kub yuav tsum tau tswj kom tsawg li sai tau.180 ℃ nyob rau hauv seem shear thiab 160 ℃ nyob rau hauv cov seem tom qab yog txaus.Feem ntau, SBS siab tshaj 200 ℃ yog qhov ua rau muaj kev laus, thiab qhov tsis hnov tsw yuav phem dua.Cov khoom TPR npaj yuav tsum tau txias kom sai li sai tau kom volatilize cov ntxhiab, thiab xyuas kom meej tias tsis muaj cua sov ntau thaum ntim.
3. Kev ua haujlwm tom ntej
Tom qab cov khoom ua si txias los ntawm TPR txhaj tshuaj molding, tsis txhob ntim lawv tam sim ntawd.Peb tuaj yeem cia cov khoom volatilize hauv huab cua li 2 hnub.Tsis tas li ntawd, cov ntsiab lus tseem tuaj yeem ntxiv thaum lub sijhawm txhaj tshuaj molding los npog qhov saj ntawm TPR nws tus kheej.
