Qhov ntsuas kub dav dav dav rau 80 ~ 90 C, qhov ntsuas kub ntawm qhov ntsuas kub no yooj yim heev kom yaj cov dej hauv cov khoom. Tab sis yuav tsum muaj qee qhov huav ntawm lub sij hawm evaporation.
Yog tias cov khoom siv raw ntawm lub hnab ntim yog hom tshiab, ntxiv cov khoom siv masterbatch, qee zaum ntxiv cov xim masterbatch, ntau qhuav, tsis tas yuav tsum nqa tawm kev sib xyaw thiab kev ua kom sov. Cia li sib tov ib pliag.
Nyob rau hauv ib txwm muaj xwm txheej, cov pellets thiab masterbatch tsis yog noo-pov thawj thiab noo-pov thawj. Tsuas yog tus tswv tsim ntawm lub ntsej muag yuav yog txias lossis yooj yim heev kom nqus dej noo los ntawm thawj lub hoobkas. Nyob rau hauv cov xwm txheej zoo li no, nws raug nquahu kom sib tov ntawm tus tswv ua ntej, tsis tas yuav yog kub. Cov lus txhuam rub tawm ib leeg thiab ua kub thiab qhuav. Tom qab ntawd ntxiv pellets thiab masterbatch thiab sib tov lawv tusyees.
Yog hais tias ib qho me me ntawm cov khoom siv rov ua dua tshiab ntxiv, cov khoom siv ntawm masterbatch thiab cov khoom siv rov ua dua tshiab tuaj yeem sib xyaw thiab ua kom sov ua ntej kom tshem tawm cov dej, thiab tom qab ntawd cov hais thiab xim masterbatch tuaj yeem sib xyaw thiab tusyees sib npaug.
Cov khoom sib xyaw cia siab rau qhov kev sib txhuam hauv nruab nrab ntawm cov khoom kom yaj lub ya raws, thiab tsis tas yuav tsum nqa tawm cov cua kub ntxiv thiab siv zog. Cov tuam txhab pab tswv yim siv cov tshuab hluav taws xob nrawm zoo ib yam li cov duab hauv 2-3. Qhov tseeb, hom kev tov no yog qhov tsis yooj yim rau kev sib tov cov ntaub ntawv yas.
Nws yog qhov tshwj xeeb tshaj yog rau kev ua cua sov thiab sib xyaw ua cov ntaub ntawv nyoos thiab khoom siv, thiab lwm yam kom siv hom khoom no. Ib qho yog qhov chaw pub noj 5-hauv chaw nres nkoj: 6 lub cev muaj zog: 7-lub cev muaj zog: 8 qhov ntsuas qhov chaw nres nkoj qhov siab-rau-dav piv. Kev Siv Zog. Qhov thib ob, Shanghai yuav tsum saib cov khoom kom qhib qhov dav, thiab ntshai tias cov qaub ncaug yuav tsis yaj. Thib peb, nws noj ntau dhau lub zog. Thib plaub, tus nqi ntawm cov tshuab thiab khoom siv yog kim heev.
