Thaum lub sijhawm ua thiab siv cov yas zaj duab xis, txhawm rau txhim kho cov khoom ntawm qee cov khoom siv resin lossis cov khoom yas tsis ua tau raws li qhov yuav tsum tau ua ntawm lawv cov thev naus laus zis ua tiav, nws yog qhov tsim nyog los ntxiv cov yas ntxiv uas tuaj yeem hloov lawv cov yam ntxwv lub cev kom hloov pauv kev ua tau zoo ntawm cov khoom. Raws li ib qho ntawm cov khoom ntxiv tsim nyog rau cov yeeb yaj kiab cua tshuab, hauv qab no yog cov lus qhia ntxaws txog cov neeg sawv cev yas. Muaj peb hom qhib nplua tus neeg sawv cev tiv thaiv kev thaiv: oleic amide, erucamide, silicon dioxide; Ntxiv rau cov khoom ntxiv, muaj cov masterbatches ua haujlwm xws li qhib masterbatches thiab du masterbatches.
1. Tus neeg sawv cev nplua
Ntxiv cov khoom xyaw du rau hauv zaj duab xis zoo li ntxiv ib txheej dej ntawm ob daim iav, ua rau zaj duab xis yas yooj yim rau kev swb ob txheej tab sis nyuaj rau cais lawv.
2. Tus neeg sawv cev qhib qhov ncauj
Ntxiv ib qho qhib lossis masterbatch rau hauv zaj duab xis zoo li siv ntawv xuab zeb los txhuam qhov chaw ntawm ob daim iav, yog li nws yooj yim cais ob txheej ntawm zaj duab xis, tab sis nws nyuaj rau swb.
3. Qhib cov masterbatch
Cov khoom muaj pes tsawg leeg yog silica (inorganic)
4. Tus tswv tsev du
Cov khoom xyaw: amides (organic). Ntxiv amide thiab anti-blocking agent rau hauv masterbatch kom muaj cov ntsiab lus ntawm 20 ~ 30%.
5. Xaiv tus neeg sawv cev qhib
Hauv cov masterbatch qhib du, kev xaiv amide thiab silica yog qhov tseem ceeb heev. Qhov zoo ntawm amide tsis sib npaug, ua rau muaj kev cuam tshuam ntawm masterbatch rau ntawm daim nyias nyias los ntawm lub sijhawm mus rau lub sijhawm, xws li saj loj, cov pob dub thiab lwm yam, tag nrho cov no yog tshwm sim los ntawm cov khoom tsis huv ntau dhau thiab cov roj tsiaj tsis huv. Hauv cov txheej txheem xaiv, nws yuav tsum tau txiav txim siab raws li kev sim ua haujlwm thiab kev siv amide. Kev xaiv silica yog qhov tseem ceeb heev, thiab nws yuav tsum tau txiav txim siab los ntawm ntau yam xws li qhov loj me ntawm cov khoom me me, thaj chaw tshwj xeeb, cov dej hauv cov ntsiab lus, kev kho qhov chaw, thiab lwm yam, uas muaj kev cuam tshuam tseem ceeb rau kev tsim cov masterbatch thiab cov txheej txheem tso tawm zaj duab xis.
