TPR yog cov ntawv luv ntawm Thermo-Plastic-Rubber khoom, TPR cov khoom siv chav tsev thermoplastic Rubber, yog ib hom roj hmab elasticity tsis muaj vulcanization, tuaj yeem ua tiav ncaj qha (xws li txhaj tshuaj molding, tshuab molding, extrusion, thiab lwm yam) thermoplastic mos roj hmab cov ntaub ntawv. .
TPR cov ntaub ntawv yog raws li thermoplastic styrene butadiene roj hmab (xws li SBS, SEBS) raws li cov khoom siv raw, ntxiv cov resin (xws li PP, PS) muab tub lim, plasticizing roj tus neeg sawv cev thiab lwm yam khoom siv ntxiv los muab cov ntaub ntawv hloov kho.
· TPR elastic hais
Cov tsos mob: Xim pob tshab lossis dawb granules, tuaj yeem hloov mus rau lwm yam xim raws li qhov xav tau. Cov duab yog ib feem, feem ntau nrog puag ncig spheroids, ellipsoids thiab zoo puag ncig tuav, qhov saum npoo yog ci, nrog kev ua haujlwm zoo dua.
· TPR elastic particle yam ntxwv ·
TPR elastic hais qhia cov khoom zoo tshaj plaws hauv kev tsim thiab ua:
① Tsis tas yuav vulcanization.
② Zoo elasticity ntawm chav tsev kub.
③ Nws muaj cov khoom ntawm cov roj hmab thiab cov yas yas.
④ Cov ntaub ntawv ntau lawm tuaj yeem rov ua dua thiab rov siv dua los txo cov nqi.
· TPR Khau Khoom ·
TPR cov khoom siv khau, yog cov thermoplastic elastomer SBS thiab lwm yam khoom siv ntxiv muab hloov kho cov khoom siv polymer, tom qab sib tov, extrusion, txhaj tshuaj molding thiab molding txheej txheem ua los ntawm cov khau. Nws muaj qhov zoo ntawm cov khoom tsis zoo, tsis tshua muaj kub tsis kam, muaj zog dabtsi yog khoov, zoo huab cua permeability, me me ntom ntom, muaj zog daim ntawv cog lus, thiab lwm yam. Yog li ntawd, cov ntaub ntawv TPR tau txais kev saib xyuas hauv kev lag luam khau.
· Production process ·
Txhawm rau txhim kho kev ua haujlwm ntawm SBS, txhim kho fluidity, flexure, anti-aging, anti-deformation, tiv thaiv hluav taws thiab txhim kho cov txiaj ntsig kev lag luam, nws yog ib qho tsim nyog yuav tau ntxiv ntau yam additives hauv cov roj hmab ntshiab rau kev sib xyaw thiab extrusion granulation, nyob rau hauv thiaj li yuav ua rau ntau yam ntawm cov khoom uas sib txawv zog.
· Daim ntawv qhia ·
Kev sib xyaw ntawm cov khoom siv raw muaj qhov cuam tshuam zoo rau kev ua haujlwm ntawm cov khoom: lub hom phiaj ntawm kev ntxiv cov khoom granular rau cov khoom ntim ntawm TPR nkawm khau yog tsuas yog txo tus nqi, thaum nce hardness thiab hnav tsis kam ntawm cov khoom, feem ntau siv. fillers yog SiO2, CaCO3, titanium dioxide, talc, dawb carbon dub; Nrog rau qhov nce ntawm cov ntaub ntawv sau, lub hardness nce pom tseeb, tab sis lub zog tensile thiab elongation ntawm tawg txo. Yog li ntawd, cov ntsiab lus filling yuav tsum tsis txhob siab dhau, thiab hom thiab ntau npaum li cas yuav tsum tau xaiv raws li qhov yuav tsum tau ua ntawm cov khoom ua tau zoo thiab kev siv tshuab. Feem ntau cov xim dawb carbon dub tsis pub tshaj 5% thiab siv nrog calcium carbonate. Calcium carbonate ntau npaum li cas yog txiav txim siab raws li cov khoom xav tau.
Tshuaj additives:Ntxiv {{0}}.5% stearic acid rau cov mis los ua si lub lubricating, sib xws, plasticizing nyhuv; Ntxiv 1-2% AC tshuab tus neeg sawv cev los ua kom lub zog nthuav dav ntawm cov khoom siv TPR tuaj yeem kov yeej qhov tshwm sim sag, thiab cov khoom nto tiav yog qhov sib xws. Micro-foaming tuaj yeem txo qhov kev faib ua feem ntawm cov khoom siv khau, uas yog qhov tsim nyog rau kev txo nqi. Txawm li cas los xij, kev ua npuas dej ntau dhau yuav cuam tshuam rau qhov ntsuas qhov zoo xws li cov khoom tawv tawv thiab lub zog, thiab nws qhov ntau npaum li cas yog tswj ntawm 0.5%.
· Daim ntawv thov khoom ·
TPR elastic particles yog siv dav hauv cov khoom siv niaj hnub, cov cuab yeej kho vajtse, hnab thiab cov log tsheb, cov khoom ua si, nws pib qhov chaw, cov khoom siv kho mob, cov xaim hluav taws xob, cov khoom siv hluav taws xob, cov cuab yeej sib txuas lus thiab cov khoom siv khau. Ntawm lawv, kev lag luam khau thiab cov khoom ua si feem ntau yog TRP daim ntawv thov teb ntawm SBS substrate; Cov ntaub ntawv hloov kho nrog SEBS raws li cov khoom siv hauv paus feem ntau yog siv rau hauv cov khoom siv nrog kev laus tiv taus, huab cua tsis kam thiab cov khoom siv lub cev tensile zog, thiab cov khoom siv tsis tshua muaj zog (tsawg dua 5 degrees Shore hardness).
Cov khoom siv khau ua los ntawm TPR elastic hais tsis tsuas yog muaj cov yam ntxwv ntawm siab elasticity thiab kub tsis kam ntawm roj hmab, tab sis kuj muaj cov yam ntxwv ntawm kev ua haujlwm yooj yim, tsis tu ncua ntau lawm thiab yooj yim rov qab ntawm cov ntaub ntawv sab. Tshwj xeeb, nws muaj qhov kub thiab txias tsis kam, kev sib txhuam coefficient siab thiab muaj zog tuav lub zog, thiab yog ib yam tshiab ntawm cov khoom siv nrog kev ua haujlwm siab thiab kev ua haujlwm yooj yim.
