Dab tsi yog ntxhia dej haus dej haus cawv siv tshuab moulding
Txawv tshuab moulding txoj kev muaj qhov sib txawv ntawm cov khoom sib txawv ntawm cov khoom sib txawv ntawm cov khoom sib txawv, kev ua raws, kev tsim thiab cov nqi.Txhua tshuab moulding txheej txheem yuav raug xa mus rau cov ntawv nyeem.Cov cov ntsiab lus ntawm tshuab moulding yog tswvcuab hauv kev pom li cas.Los molding hla cov khoom muaj xws li peb txoj kev loj: extrusion tshuab moulding: mas siv rau kev ua haujlwm tsis muaj leej twg; Txhaj tshuab moulding: yog siv rau cov tub ntxhais hlau kev ua haujlwm pwm tsis tiav; ncab ib lub tshuab molding. Nws muaj peev xwm tsim cov khoom siv muag khoom zoo nkauj, txo cov nqi khoom thiab kev txhim kho cov khoom ua tiav. Ntxiv rau, muaj tshuab multilayer moulding, nias tshuab moulding, dip txheej tshuab molding, foaming tshuab molding, 3-dimensional tshuab molding thiab li.Yog li, 75 % ntawm tshuab molding cov khoom yog moulded los ntawm extrusion, 24% ntawm txhaj, thiab 1% los ntawm lwm lub tshuab molding khoom.Txhua tag nrho tshuab molding khoom, 75% yog bidirectional stretch khoom.Qhov zoo ntawm extrusion tshuab moulding yog cov muaj ntau lawm efficiency, tsis khoom tus nqi qis, kev xaiv cov pwm thiab lub cav, tab sis cov kev tsis zoo siab yog cov nqi seem, cov khoom siv khib nyiab thiab siv cov khoom siv khib nyiab, kev tswj cov khoom siv thiab cov khoom pov tseg ntawm cov ntaub ntawv tsis txaus, thiab cov kev ua haujlwm yuav tsum tau muab coj los tom qab sib sau. Qhov zoo ntawm kev txhaj tshuaj thiab tshuab molding yog tias tsis muaj khib nyiab yog tsim nyob rau hauv tus txheej txheem ntawm kev ua, lub phab ntsa tuab ntawm cov khoom thiab cov dispersal ntawm cov ntaub ntawv yuav ua tau zoo tswj, nplua caj dab khoom muaj siab ua zoo tshaj plaws, qhov khoom deg yog du thiab huv, thiab cov khoom siv me me yuav raug coj tawm kev lag luam.Qhov kev tsis zoo yog qhov siab ntawm kev tsim khoom, thiab rau ib qhov twg tsuas tsim rau me me tshuab moulding cov khoom.Qhov txheej txheem ntawm hollow tshuab molding yuav tsum tau hais tias cua compressed ntawm nruab nrab ntawm daim tshuab dawb ntawm tshuab moulds yuav tsum huv.Qhov huab cua siab ntawm txhaj tshuaj molding yog 0.55 ~ 1MPa.The extrusion tshuab siab yog 0.2l ~ 0.62mpa, thaum lub tshuab ua kom ncav siab feem ntau mus txog 4MPa.Thaum cov txheej txheem ntawm cov yas nplaum, ua rau siab ua rau tsis muaj kev ntxhov siab, tsis muaj teeb meem kev nyuab siab, thiab kev ntxhov siab tsis tuaj yeem txhim kho cov teeb meem, qhov cuam tshuam thiab cov khoom khoov ntawm cov khoom
