Muaj ib tug dawb band rau saum npoo ntawm PVC ua npuas ncauj board, uas yog, ib tug dawb txoj kab ncaj nraim nrog tib extrusion kev taw qhia raws li lub rooj tsavxwm, uas ncaj qha mus cuag lub nto ntawm lub slab thiab tsim board sib haum mus rau lub qhov ncauj pwm thiab cov dawb band. Cov yam ntxwv ntawm kev sib txhuam, qhov sib txawv ntawm txoj siv dawb thiab txoj siv tawv dub nyob hauv lawv qhov kev sib cuag nrog cov qauv molding. Lub molding degree yog txawv. Grey yog tus yam ntxwv uas cov leucorrhea residuals pib degrade; Bright band yog tus yam ntxwv ntawm kev sib cuag ncaj qha ntawm slab thiab sib sau.
1. Qhov kev tshem tawm ntawm ntu sib raug rau qhov tuag thiab txoj siv tawv dawb tau teeb tsa me me, ua rau muaj qhov ntws me me. Lub thickness ntawm yaj yog me ntsis txo thaum nws yog extruded los ntawm cov tuag. Txoj siv tawv dawb tsis tiv tauj thiab rub nrog lub phaj sizing thaum nws dhau los ntawm lub phaj sizing.
2. Cov khoom siv yog tov nrog impurities tsis huv thiab tseem nyob rau hauv qhov tuag, ua rau txo qis ntawm cov dej ntws thaum extruding los ntawm qhov tuag, tshwj xeeb tshaj yog ntxiv cov khoom siv tsis huv los yog cov khoom siv nyuaj. Lub stabilizer tsis muaj cov khoom siv rov ua dua ntau dhau, thiab cov yaj yog khaws cia thaum extruding los ntawm ib feem ntawm qhov tuag. Yog tias qhov teeb meem ntawm leucorrhea tsis tau daws raws sijhawm, nws yuav maj mam dhau los ua lub teeb grey siv thiab siv tawv dub raws li lub sijhawm dhau mus.
3. Kev tswj qhov kub thiab txias ntawm extruder yog tsis tsim nyog, tsis siv cov ntsia hlau kub tswj, thiab cov khoom siv nyob rau hauv extruder. Qhov kub ntawm qhov extrusion seem ntawm cov tub ntxhais sib txuas los yog tuag tsis sib npaug, thiab cov micro degradation hauv zos tshwm sim. Adhesive: Thaum cov yaj yog extruded los ntawm qhov tuag, qhov ntws ntawm ib feem ntawm qhov tuag yog me me. Ntau qhov kev xyaum tau ua pov thawj tias kev kho mob ntawm leucorrhea yog raws sijhawm. Yog tias qhov kev kho mob tsis raug raws sijhawm lossis kev hloov pauv ntawm txoj siv dawb mus rau txoj siv tsis muaj tshauv, kev kho mob ntawm extruder screws yuav poob rau hauv cov txheej txheem ntawm kev kho mob.
Ua npuas ncauj cell ntawm qhov chaw ntawm PVC ua npuas ncauj board yog lub manifestation ntawm tsawg hauv zos ntom ntawm yaj. Feem ntau, ua npuas ncauj cell muaj ob yam ntxwv: ib lub cell thiab ib puag ncig cell. Cov yam cuam tshuam muaj xws li resin. Ua npuas ncauj. Regulators. calcium carbonate. Raw khoom yam xws li stabilizer kuj muaj feem xyuam rau pwm thiab txheej txheem. Yog tias muaj thaj tsam loj ntawm npuas pores ntawm cov khoom ua npuas ncauj, cov chaw tsim khoom ntawm PVC ua npuas ncauj tuaj yeem kho cov kev kho cov npuas dej kom zoo; Yog tias ib tus neeg ua npuas ncauj qee zaus tshwm sim ntawm qhov chaw ua npuas ncauj, nws zoo li cov txheej txheem sib xyaw nrog cov sib tov tsis ua raws. Kub. Cov txheej txheem pub mis, uas ua rau tsis sib xws, yuav tsum tau hloov; Yog hais tias puag ncig ua npuas ncauj qhov tshwm sim tsis tu ncua, qhov ntau npaum ntawm daj thiab dawb ua npuas ncauj yuav tsum tau kho kom haum; Yog tias qhov ntev ua npuas ncauj qee zaum tshwm sim rau ntawm qhov chaw ua npuas ncauj, qhov no yog tus yam ntxwv ntawm qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom. Qhov laj thawj yog qhov nyuaj, thiab nws yuav tsum tau txiav txim siab raws li lub sijhawm, qhov chaw thiab qhov tshwm sim ntawm qhov ua npuas ncauj.
