Xov Xwm - Daws Cov Teeb Meem EVA Ua Npuas Ncauj

Nyob rau xyoo tas los no, kev lag luam khau thoob ntiaj teb tau pom tias muaj kev sib tw ntau ntxiv, ua rau muaj kev sib tw ntawm cov hom lag luam nruab nrab mus rau qib siab. Kev nkag mus tas li ntawm cov tswv yim tshiab thiab cov thev naus laus zis hauv khau tau tsav kom muaj kev xav tau ntau rau cov khoom siv ua npuas ncauj hauv kev lag luam khau. Cov khoom siv ua npuas ncauj polymer ua tau zoo tau dhau los ua lub hauv paus ntawm ntau yam khoom lag luam, tshwj xeeb tshaj yog hauv kev lag luam khau kis las.

Ib khub khau kis las ib txwm muaj peb ntu tseem ceeb: sab saud, nruab nrab, thiab sab nraud.

Lub hauv paus nruab nrab yog qhov tseem ceeb hauv kev muab kev nplij siab, kev rov qab los, thiab kev nqus lub zog thaum ua si nawv. Nws ua kom muaj kev tiv thaiv thiab kev xis nyob, ua rau nws yog tus ntsuj plig ntawm cov khau kis las. Cov khoom siv thiab cov thev naus laus zis ua npuas ncauj ntawm lub hauv paus nruab nrab sib txawv cov thev naus laus zis tseem ceeb ntawm ntau lub npe loj.

EVA—Cov Khoom Siv Ua Npuas Ncauj Siv Thaum Ntxov Rau Khau:

Ethylene-vinyl acetate copolymer (EVA) yog cov khoom siv ua npuas ncauj thaum ub uas siv rau hauv cov khau nruab nrab. Cov ua npuas ncauj EVA ntshiab feem ntau muaj qhov rov qab los ntawm 40-45%, ntau dua cov ntaub ntawv xws li PVC thiab roj hmab hauv kev ua kom ruaj khov, ua ke nrog cov yam ntxwv xws li lub teeb yuag thiab yooj yim ua.

Hauv kev lag luam khau, EVA cov txheej txheem ua npuas dej feem ntau suav nrog peb hom: ib txwm tiaj tus loj ua npuas dej, ua npuas dej me me hauv pwm, thiab txhaj tshuaj ua npuas dej hla kev sib txuas.

Tam sim no, kev txhaj tshuaj hla-txuas ua npuas ncauj tau dhau los ua cov txheej txheem tseem ceeb hauv kev ua cov khoom siv khau.

Cov Teeb Meem ntawm EVA Ua Npuas Ncauj:

Ib qho teeb meem uas feem ntau tshwm sim nrog cov ua npuas dej EVA no yog lawv qhov elasticity tsawg, uas cuam tshuam rau lawv lub peev xwm los muab kev txhawb nqa zoo tshaj plaws, tshwj xeeb tshaj yog hauv cov ntawv thov xws li khau kis las. Lwm qhov teeb meem uas feem ntau tshwm sim yog qhov tshwm sim ntawm kev sib sau ua ke thiab thermal shrinkage dhau sijhawm, cuam tshuam rau kev ruaj khov. Ntxiv mus, Hauv cov ntawv thov uas qhov kev tiv thaiv kev plam thiab kev tiv thaiv kev sib txhuam yog qhov tseem ceeb, cov ua npuas dej EVA ib txwm yuav tsis ua tiav cov qauv xav tau.

Txhawm rau txhim kho cov khoom siv lub cev ntawm EVA ua npuas ncauj, cov chaw tsim khoom feem ntau qhia cov khoom siv elastic xws li EPDM, POE, OBCs, thiab TPE xws li SEBS rau hauv EVA raw cov ntaub ntawv. Kev koom ua ke ntawm EPDM rau cov khoom roj hmab, POE rau qhov elasticity siab, OBCs rau cov khoom siv crystallinity mos, TPE rau kev ywj pheej, thiab lwm yam, lub hom phiaj yog ua tiav cov hom phiaj hloov kho. Piv txwv li, los ntawm kev ntxiv POE elastomers, qhov rov qab ua kom muaj zog ntawm cov khoom feem ntau tuaj yeem nce mus txog 50-55% lossis siab dua.

Kev Tsim Kho Tshiab EVA Ua Npuas Ncauj: Si-TPV Modifier rau Kev Ua Haujlwm Zoo Dua thiab Kev Ua Haujlwm Zoo Dua

SILIKE Si-TPV nthuav qhia lwm txoj hauv kev hauv EVA, tsis yog tsuas yog daws cov teeb meem kev ua tau zoo xwb tab sis kuj sib haum nrog cov kev pib ua haujlwm zoo rau ib puag ncig. Nws cov khoom tsim tshiab thiab cov txheej txheem tsim khoom pab txhawb kom ntseeg tau tias cov khoom khaws cia lawv qhov kev ncaj ncees thiab kev ua haujlwm ntev dua, ua rau lawv txhim khu kev qha thiab ruaj khov dua. ua kom ntseeg tau tias cov khoom tiav tiav siab dua.

Si-TPV (vulcanizate thermoplastic silicone-based elastomer) yog 100% recyclable elastomer khoom, Piv rau OBC thiab POE, nws txo qhov compression set thiab cua sov shrinkage ntawm EVA ua npuas ncauj cov ntaub ntawv. Ntau qhov tseem ceeb txhim kho elasticity, softness, anti slip, thiab abrasion tsis kam, txo DIN hnav los ntawm 580 mm.³mus txog 179 hli³.

Ntxiv mus, Si-TPV ua rau cov xim ntawm EVA ua npuas ncauj ntau dua. Qhov kev tshawb pom no tso cai rau cov chaw tsim khoom tsim cov khoom zoo nkauj yam tsis muaj kev cuam tshuam rau kev ua tau zoo.

Qhov Si-TPV no ua ib qho kev hloov kho tshiab rau EVA ua npuas ncauj pab txhawb kev tsim cov khoom siv EVA ua npuas ncauj uas xis nyob thiab ruaj khov xws li cov khau nruab nrab, cov khoom siv huv, cov khoom siv kis las, cov plag tsev, cov lev yoga, thiab ntau ntxiv.

Tshawb Nrhiav Yav Tom Ntej ntawm EVA Ua Npuas Ncauj nrog SILIKE Si-TPV! Txhawb koj cov khoom mus rau qhov siab tshiab ntawm kev ua tau zoo thiab zoo. Tso tawm lub peev xwm ntawm peb cov kev hloov kho Si-TPV rau cov kev ua tau zoo tsis muaj qhov sib xws hauv koj daim ntawv thov EVA ua npuas ncauj.
