Kev tsim cov txheej txheem ntawm pvc profile yas extrusion
Squeeze forming yog hais txog cov txheej txheem ntawm kev txuas ntxiv cov ntaub ntawv yas los ntawm kev muab kauv extrusion.
Nyem cov khoom melted los ntawm lub thoob mus rau lub taub hau ntawm lub tshuab, thiab ua rau nws mus rau hauv ib tug pwm zoo li dawb paug los ntawm lub taub hau pwm.
Thaum lub sij hawm txias pwm txheej txheem, cov cuab yeej rub tawm tsis tu ncua tshem tawm cov khoom tsim los ntawm pwm kom tau txais cov khoom xav tau.
Yuav kom tau txais cov profiles nrog cov tsos zoo thiab sab hauv zoo, nws yog ib qho tsim nyog yuav tsum nruj me ntsis tswj cov txheej txheem extrusion thiab nruj me ntsis tswj nws.
Lub hom phiaj yog nyob rau hauv qhov sib tov, molding kub, ntsia hlau txias thiab kev sib hloov ceev, extrusion siab, txias thiab shaping, thiab lwm yam.
Sib tov
Cov txheej txheem sib xyaw ua ntej ntxiv PVC resin thiab cov khoom sib piv rau cov khoom siv kub, thiab tom qab ntawd do ntawm kev kub ceev.
Qhov sib tov kub yog 120 degree. Tom qab stirring tusyees, muab tso rau hauv ib tug txias tov thiab do ntawm ib ncig ntawm 45 degrees.
Loose thiab yooj yim ntws hmoov sib tov, tshem tawm thiab tso tseg. Kev tswj qhov kub thiab txias yog qhov tseem ceeb thaum lub sij hawm sib tov.
Yog hais tias nws yog siab, cov khoom yog yooj yim mus sticking, clumping, thiab uneven plasticization.
Qhov no yog lub hom phiaj zoo. Yog li ntawd, feem ntau, qhov kawg kub ntawm qhov kub-kub stirring yog (115-120) degree , thiab lub sij hawm stirring yog ntev dua.
Tom qab 10 mus rau 15 feeb, qhov tso tawm ntawm qhov sib tov txias yog 45 degree.
Extrusion ua kub
Cov pvc profile yas extrusion uas tsim los ntawm peb lub tuam txhab yog ntxaib ntsia hlau extruders nrog rau kev ua haujlwm.
Los ntawm cov txheej txheem xws li preheating, pub, conveying, tso, thiab melting, cov khoom yog uniformly plasticized thiab zoo li tus ua ntej nkag mus rau hauv lub tshuab.
Ntxiv uniformity yog tiav tom qab lub taub hau, thiab nyob rau hauv lub siab ntawm lub taub hau, nws yog extruded mus rau hauv ib tug tuab billet, uas ntws tsis tu ncua nyob rau hauv lub xeev ntws.
Lub extrusion forming kub plays lub luag haujlwm tseem ceeb hauv plasticization thiab melting ntws ntawm plastics.
Qhov zoo thiab cov khoom tsim tawm ntawm cov khoom tiav plasticization thiab pvc profile yas extrusion khoom yog zoo sib xws.
Vim qhov ze ze ntawm cov txheej txheem kub thiab decomposition kub ntawm PVC, kev tswj nruj yog tsim nyog.
Feem ntau, kev tswj qhov kub ntawm lub extruder feem ntau yog ua tiav los ntawm kev tswj qhov kub thiab txias los ntawm cov khoom noj ntawm lub thoob mus rau seem extrusion, thiaj li yuav cais cov khoom ntawm cov khoom hauv lub xeev.
Cov hmoov los yog cov khoom maj mam yaj, ua rau zoo dua plasticity ntawm cov khoom. Raws li cov txheej txheem extrusion xav tau, qhov kub ntawm txhua ntu yuav tsum tau ua raws li txheej txheem extrusion.
Txiav txim siab raws li tus yam ntxwv ntawm lub tshuab, cov yam ntxwv ntawm cov khoom siv mis, thiab cov kev xav tau zoo ntawm cov khoom. Extrusion ua kub
Nws feem ntau yog hais txog qhov kub thiab txias ntawm cov yas, uas yog txiav txim siab los ntawm qhov kub ntawm lub thoob thiab cov ntsia hlau.
Kev ntsuas thiab tswj tau yooj yim, feem ntau yog siv qhov ntsuas kub ntawm qhov ntsuas kub los ntsuas qhov ntsuas kub, thiab siv cov thermocouples los tswj. Hauv kev siv
Thaum ntxaib-ntsia hlau extrusion yog siv, qhov kub ntawm qhov chaw pub mis yog siab tshaj qhov kub melting ntawm resin. Tshooj pub, seem compression
Hauv thaj chaw tso pa thiab homogenization, qhov kub thiab txias feem ntau nthuav tawm lub eeb zoo li tus yam ntxwv.
Qhov kub ntawm lub nozzle muaj qhov cuam tshuam loj rau extrusion molding. Lub taub hau kub yuav tsum tau khaws cia nyob rau hauv qhov kub thiab txias.
Nws tuaj yeem ua tiav cov tsos zoo thiab cov khoom siv kho tshuab, txo qhov nthuav dav ntawm lub qhov hluav taws xob yaj.
