Qhov sib xyaw ua ke kub yog 80 ~ 90C, qhov ntsuas kub no yooj yim rau volatilize cov dej hauv cov khoom. Txawm li cas los xij, nws yuav siv sijhawm qee lub sijhawm kom evaporate.
Yog tias cov khoom siv raw ntawm lub hnab ntim khoom yog cov khoom siv tshiab, ntxiv masterbatch, thiab qee zaum ntxiv xim masterbatch, kuj qhuav, yog li tsis tas yuav tsum sib tov thiab cua sov. Cia li do ib pliag.
Raws li ib txwm muaj, cov pellets thiab masterbatch tsis muaj cov dej noo thiab tsis nqus dej noo. Tsuas yog tus masterbatch tuaj yeem tawm hauv lub Hoobkas ntub lossis yooj yim nqus dej. Hauv qhov no, nws raug nquahu kom do cov masterbatch ua ntej, thiab kev sib xyaw cua sov tsis tsim nyog. Cov particle rub tawm ib leeg. Ua npaws thiab qhuav. Tom qab ntawd ntxiv pellets thiab masterbatch thiab sib tov lawv tusyees.
Yog tias ntxiv me me ntawm cov khoom siv rov ua dua tshiab, sib tov cov masterbatch thiab cov khoom siv rov ua dua kom tshem tawm cov dej noo ua ntej, ces ntxiv cov pellets thiab masterbatch thiab sib tov sib npaug.
Kev sib xyaw yog ua raws li kev sib txhuam ntawm cov khoom siv los ua kom muaj dej noo, thiab tsis tas yuav tsum tau ua kom sov nws kom nkim cua sov. Chav tsev pab tswv yim siv lub tshuab ua kom siab ceev zoo ib yam li daim duab 2-3. Qhov tseeb, hom kev tov khoom no tsis haum rau kev sib xyaw cov ntaub ntawv yas.
Nws yog tshwj xeeb tshaj yog haum rau cua sov thiab sib tov ntawm tej ntaub ntawv thiab slurries, thiab lwm yam. Hom kev tov khoom no yog siv rau kev sib tov thiab knitting sib tov khoom. Laborious, thib ob, Shanghai yuav tsum tau saib xyuas cov ntaub ntawv, thiab twv tsis evaporate dej. Thib peb, kev siv hluav taws xob ntau dhau; thib plaub, cov khoom siv kim heev.
