Cuamtxhaj tshuaj moldingtuaj yeem siv los txhawm rau txhim kho cov khoom ua haujlwm, xws li txhim kho tshuaj lom neeg muaj zog, tuav ntau ntxiv, softer thiab kov kom zoo nkauj dua.
Qhov kev txhaj tshuaj molding ob zaug yog pib siv los ua kom pom kev zoo nkauj ntawm cov neeg siv khoom thiab tam sim no nrov heev. Cov txuj ci no tau siv rau hauv ntau daim ntawv thov, thiab tuaj yeem siv los txhim kho lub zog ua haujlwm, xws li txhim kho tshuaj lom neeg, txhim kho tuav, softer thiab ntau dua ntxim nyiam kov.
Ob chav txhaj tshuaj molding kev txawj: cov ntaub ntawv uas nquag siv nyob rau hauv qhov chaw txhaj tshuaj txhaj tshuaj yog thermoplastic elastomer (TPE). Cov ntaub ntawv muaj ntau yam uas tuaj yeem siv rau kev txhaj tshuaj txhaj tshuaj molding tau ntxiv rau ntxiv. Rau cov lus txhaj tshuaj txhaj tshuaj rau ntawm cov khoom siv hauv paus (xws li ABS, PC, PC / ABS, PA thiab San), SEBS, tpe-v, tpe-u, TPE-E thiab tpe-a tau siv dav.
Txawm hais tias nws yog ntxig txhaj tshuaj molding lossis theem nrab txhaj tshuaj molding, thermoplastic elastomer (TPE) yog txhaj rau hauv qhov sib txuam txhaws qis. Qhov no ua rau" muag npog tawv" cov khoom lag luam ntau dua, xws li kev rwb thaiv tsev, tshuaj tiv thaiv tshuaj, ntau dua ergonomic, zoo dua hnov, tuav thiab sab saum toj zoo nkauj zoo nkauj.
Ntxig moulding: hauv kev ntxig molding, ib feem tsis yeem (feem ntau cov tawv ntawm cov yas) yog tsim thiab tau ntim rau hauv cov pwm kab noj hniav. Tom qab ntawd, TPE txhaj tshuaj molding siv rau ntawm cov khoom tivthaiv no kom tau txais cov khoom lag luam zoo. Cov cuab yeej siv txhaj tshuaj siv tau rau kev txhaj tshuaj molding. Qhov kev tso kawm ntawm qhov chaw tsis tuaj yeem tuaj yeem ua tiav los ntawm kev tuav lossis kev tuav caj npab.
Kev txhaj tshuaj rau cov pwm thib ob: kev txhaj tshuaj rau lub tshuab pwm tseem hu ua kev txhaj tshuaj moulding, ob chav xim moulding lossis cov khoom siv molding. Lub tshuab tshwj xeeb siv nyob rau hauv cov ntaub ntawv no muaj ntau lub nruas, uas yog siv los sau cov ntaub ntawv sib txawv rau tib lub pwm. Hauv kev txhaj tshuaj txhaj tshuaj tiv thaiv, kev sib khi ntawm cov khoom siv dag zog thiab TPE yog qhov tseem ceeb ntawm txoj kev ua tiav. Cov nplaum tsis zoo tuaj yeem ua rau muaj teeb meem xws li tev tawm, khoov, hnav lossis ua kom tsis zoo. Qhov sib xyaw ua ke ntawm ob cov ntaub ntawv thiab kev ua haujlwm kub yog qhov tseem ceeb uas cuam tshuam rau lub zog khi.
Cov khoom siv ua tau: kev sib zog lub zog ntawm cov sib txawv nyuaj / cov khoom siv mos
Kev ua haujlwm kub: nws qhia txog kev sib txheeb ntawm TPE melting kub, qhov kub tsis yeem substrate thiab qhov muaj zog muaj zog. Daim ntawv thov ntawm TPE nyob rau hauv kev sib txuas txhaj tshuaj molding thermoplastic elastomer raws li polyester (TPE-E lossis tiv) yog tsim los ntawm DSM engineering plastics. Hom polyester elastomer sib txuas lub zog thiab ua cov yam ntxwv ntawm yam xws li tshuab ua hluav taws xob nrog rau kev ua haujlwm ntawm thermosetting elastomer, uas txhim kho cov ua, ua kom tiav thiab tshuaj lom neeg kuj.
Feem ntau ntawm cov ntaub ntawv muag muag ntxig ntawm kev txhaj tshuaj duplex koom nrog kev txhaj tshuaj ntawm ib txheej nyias ntawm cov khoom muag (TPE) mus rau qhov nyuaj txheej. Vim tias TPE feem ntau yuav tsum ntws los ntawm txoj kev ntev thiab nyias nyias ntawm phab ntsa kom sau cov pwm, TPE yuav tsum muaj kev kub siab. Qhov tsawg viscosity khoom tshwj xeeb kev pom zoo ua qhov kev cuam tshuam tseem ceeb rau kev txhaj tshuaj tiv thaiv kev txhaj tshuaj thiab yog cov ntaub ntawv nyiam rau kev siv daim ntawv thov no.
Cov tshuaj rau hauv lub cev: TPE sib raug zoo nrog cov ntawv thau khoom loj (xws li PC, PC / ABS, ABS) siv los ua cov txheej txheem tawv tawv tom qab sib xyaw tshuaj molding. Vim tias qhov kev nplaum zoo no, txawm tias qhov hnyav siab dhau los, nws yuav tsis ua kom pom qhov zoo ntawm lub delamination nrog lub substrate.
Nyob rau hauv tus txheej txheem ntawm kev xaiv tus txheej txheem sab nrauv elastomer, TPE muaj cov yam ntxwv ua tau zoo heev thiab muaj qhov pom tau zoo tshaj plaws, thiab muaj feem xyuam rau kev ua haujlwm zoo ntawm TPE nyob rau hauv kev txhaj tshuaj sib xyaw. Daim ntawv thov kev siv lub cev sib txuas lossis phau ntawv sib xyaw: kev sib xyaw cov cuab yeej feem ntau yog siv los txhim kho kev sib koom tes nrog lub hauv qab thaum ob leeg txhaj tshuaj molding yog ua los ntawm TPE thiab tsis-polar polymer (xws li PP) lossis Pa. Tsis tas li ntawd, cov nplaum lossis primer tuaj yeem siv txhim kho qhov kev hloov kho kom yooj yim ntawm TPE yooj thiab polymer tsis yeem
