Yuav ua li cas xim masterbatch tau ntxiv rau yas thaum txhaj tshuaj molding?

Xim masterbatch yog tov rau hauv cov polymer nyoos ntawm lub hopper los yog pub ncaj qha rau hauv lub caj pas ntsia hlau siv lub gravimetric lossis volumetric doser. Rau kev txhaj tshuaj molding, qhov piv txwv li ib txwm yog 1-4% los ntawm qhov hnyav-1-2% rau cov xim opaque, 2-4% rau cov xim zoo nkauj lossis ci ntsa iab. Cov pellets yaj thiab disperse tusyees raws li cov ntsia hlau tig, xim cov yaj ua ntej nws nkag mus rau hauv pwm. Pib los ntawm kev teeb tsa lub doser rau qhov feem pua ​​​​ntawm cov hom phiaj, khiav ob peb qhov tshuaj tua kab mob kom tshem tawm cov khoom qub, tom qab ntawd pwm qhov chaw kuaj. Tshawb xyuas cov xim sib xws ntawm thawj ob peb qhov kev txhaj tshuaj- kho tus nqi pub yog tias cov streaks tshwm. (xim masterbatch) nrog cov xim siab loading disperses sai dua thiab xav tau tsawg feem pua, txuag nqi ntawm kev khiav loj. Ua ntej-qhuav hygroscopic resins kom tsis txhob ya raws splay uas tuaj yeem ua rau xim daj. Ntxuav lub hopper thiab ntsia hlau ntawm kev hloov xim kom tsis txhob muaj kab mob. Ntau cov molders khiav masterbatch ntawm central conveying tshuab rau ntau lub tshuab. Kev sib ntxiv kom zoo muab cov khoom sib xws, tsis muaj qhov tsis sib xws txhua lub voj voog yam tsis muaj kev cuam tshuam los yog lub zog thaum noj kom raug.
