Dab tsi yog cov txheej txheem xim rau kev txhaj tshuaj molding?

Tam sim no, daim ntawv thov ntawm kev txhaj tshuaj molded qhov chaw yog qhov dav heev. Nyob rau hauv kev ua lag luam, cov khoom txhaj tshuaj muaj cov yeeb yuj thiab cov xim sib txawv, yog li yuav ua li cas rau cov txheej txheem txhaj tshuaj? Hauv qab no peb yuav qhia luv luv txog peb hom xim ntawm kev txhaj tshuaj molding, vam tias yuav pab tau rau txhua tus.

Feem ntau cov khoom lag luam yas yog xim ntawm cov tshuab txhaj tshuaj molding, thaum feem ntau cov yas yas twb muaj xim rau muag.

2. Xim Masterbatch xim txoj kev rau kev txhaj tshuaj molded qhov chaw, cov khoom siv granulating thiab cov khoom ua kua, tuaj yeem muab sib xyaw ua ntau yam xim. Cov khoom siv yog cov khoom siv ntau tshaj plaws, thiab cov masterbatches tuaj yeem siv los ntawm kev sib xyaw cov yas nrog cov masterbatches los thauj cov sib tov lossis masterbatches mus rau hauv lub tshuab txhaj tshuaj molding. Qhov zoo yog: cov xim pheej yig dua, cov teeb meem plua plav qis dua, cov khoom siv qis dua, kev cia yooj yim dua.

3. Kev txhaj tshuaj molding qhuav colouring txoj kev yog qhov pheej yig tshaj plaws, nws qhov tsis zoo yog thaum siv plua plav thiab qias neeg. Txhawm rau kom muaj xim zoo ib yam thiab muaj tseeb hauv cov txheej txheem tsim khoom, cov hnab tshwj xeeb lossis cov thawv tuaj yeem siv los sau cov xim qhuav xim hmoov. Thaum siv cov hmoov pleev xim qhuav, cov khoom siv yas yuav tsum tau them nrog cov xim tsis sib xws, kom cov xim tuaj yeem sib npaug hauv cov kua nplaum yaj, nws txoj kev sib xyaw thiab lub sijhawm yuav tsum tau ua raws li cov qauv kom ntseeg tau tias cov xim tsis sib xws.

Tom qab txiav txim siab cov kauj ruam xim, peb yuav tsum ua siab ntev. Tsis tas li ntawd kom tsis txhob muaj xim hmoov nyob rau hauv lub sij hawm cia kom nqus noo noo, txwv tsis pub yooj yim rau tawg, kom cov tshuaj txhaj tshuaj tshwm sim cov cim.
