TPE raw khoom yog ib puag ncig tus phooj ywg, tsis muaj tshuaj lom thiab muaj kev nyab xeeb khoom, nrog rau ntau yam hardness (0-95A), zoo heev colorability, mos kov, huab cua tsis kam, qaug zog kuj thiab kub tsis kam, zoo ua hauj lwm zoo, tsis xav tau Vulcanized, thiab tuaj yeem siv tau los txo cov nqi, yog li ntawd, TPE raw cov ntaub ntawv yog dav siv hauv kev txhaj tshuaj molding, extrusion, tshuab moulding, molding thiab lwm yam kev ua. Yog li koj puas paub dab tsi yuav tsum tau rau lubtxhaj tshuaj moldingtxheej txheem ntawm TPE raw khoom yog? Cia peb saib cov hauv qab no.
TPE raw khoom txhaj tshuaj molding txheej txheem yuav tsum:
1. Qhuav cov khoom siv TPE.
Feem ntau, yog tias muaj cov kev cai nruj ntawm cov khoom siv TPE, TPE raw cov ntaub ntawv yuav tsum tau qhuav ua ntej txhaj tshuaj molding. Vim hais tias hauv kev txhaj tshuaj molding ntau lawm, TPE raw cov ntaub ntawv feem ntau muaj qhov sib txawv ntawm cov dej noo thiab ntau lwm yam tsis tshua muaj molecular-yuag polymers. Yog li ntawd, cov dej ntsiab lus ntawm TPE raw cov ntaub ntawv yuav tsum tau ntsuas ua ntej, thiab cov uas muaj dej ntau dhau yuav tsum tau qhuav. Txoj kev ziab dav dav yog siv lub tshuab ziab kom qhuav ntawm 60 ℃ ~ 80 ℃ rau 2 teev. Lwm txoj hauv kev yog siv lub tshuab ziab khaub ncaws kom qhuav, uas tuaj yeem muab cov khoom kub kub tsis tu ncua rau lub tshuab txhaj tshuaj molding, uas yog qhov zoo rau kev ua haujlwm yooj yim, tswj kev huv, txhim kho zoo, thiab nce kev txhaj tshuaj.
2. Sim zam kom tsis txhob kub kub txhaj tshuaj molding.
Raws li lub hauv paus ntawm kev ua kom zoo ntawm plasticization, qhov kub ntawm extrusion yuav tsum raug txo kom ntau li ntau tau, thiab kev txhaj tshuaj siab thiab cov ntsia hlau ceev yuav tsum tau nce ntxiv kom txo tau cov viscosity ntawm cov yaj thiab txhim kho cov fluidity.
3. Teem qhov tsim nyog TPE txhaj tshuaj kub.
Nyob rau hauv cov txheej txheem ntawm kev txhaj tshuaj molding TPE raw cov ntaub ntawv, qhov dav dav qhov kub ntawm txhua qhov chaw yog: chim 160 ℃ to 210 ℃, nozzle 180 ℃ to 230 ℃. Qhov kub ntawm cov pwm yuav tsum siab tshaj qhov ntsuas kub ntawm qhov chaw txhaj tshuaj molding, yog li kom tsis txhob muaj kab txaij ntawm cov khoom thiab qhov tsis xws luag ntawm kev txhaj tshuaj molding txias kua nplaum, yog li cov pwm kub yuav tsum tau tsim kom nyob nruab nrab ntawm 30 ℃ thiab 40 ℃.
4. Kev txhaj tshuaj ceev yuav tsum yog los ntawm qeeb mus nrawm.
Yog tias nws yog ob peb theem ntawm kev txhaj tshuaj, qhov nrawm yog los ntawm qeeb mus rau nrawm. Yog li ntawd, cov pa roj hauv pwm tau yooj yim tawm. Yog tias sab hauv ntawm cov khoom yog qhwv hauv cov pa roj (ntws hauv), lossis yog tias muaj dents, qhov ua kom yuam kev tsis zoo, txoj kev no tuaj yeem hloov kho. Kev txhaj tshuaj nrawm yuav tsum tau siv hauv SBS systems. Hauv SEBS system, yuav tsum siv qhov kev txhaj tshuaj ntau dua. Yog tias cov pwm muaj qhov tso tawm txaus, txawm tias kev txhaj tshuaj nrawm tsis tas yuav txhawj xeeb txog huab cua.
5. Ua tib zoo tswj xyuas qhov kub thiab txias.
Kev ua haujlwm kub ntawm TPE cov ntaub ntawv raw yog kwv yees li 200 degrees, thiab TPE yuav tsis nqus dej noo hauv huab cua thaum khaws cia, thiab feem ntau tsis tas yuav ua kom qhuav. Ci ntawm qhov kub thiab txias rau 2 mus rau 4 teev. TPE encapsulated ABS, AS, PS, PC, PP, PA thiab lwm yam ntaub ntawv yuav tsum tau ua ntej ci thiab ci ntawm 80 degrees rau 2 mus rau 4 teev.
Hauv cov ntsiab lus, nws yog TPE raw khoom txhaj tshuaj molding txheej txheem. TPE raw khoom yog cov khoom siv thermoplastic elastomer dav siv, uas tuaj yeem txhaj tshuaj molded ib leeg lossis thermally bonded nrog PP, PE, ABS, PC, PMMA, PBT thiab lwm yam khoom siv rau kev txhaj tshuaj molding, thiab cov khoom siv tuaj yeem siv dua. Kev nyab xeeb thiab ib puag ncig tus phooj ywg, nws twb dhau los ua ib tiam tshiab ntawm cov khoom siv roj hmab nrov thiab yas.
