Kev txheeb xyuas dej-Raws li txheej txheem xim xim: Lub Tsev Cov Ntsiab Cai ntawm Kev Tsim Kho Ntsuab

Raws li tus neeg sawv cev ntawm cov xim ntsuab thiab ib puag ncig tus phooj ywg, dej- cov xim pleev xim sib koom ua ke nrog cov txheej txheem txheej txheem, tab sis muaj qhov sib txawv tseem ceeb hauv kev xaiv raw khoom thiab kev tswj cov txheej txheem. Cov txheej txheem kev tshawb fawb nruj heev tsis tsuas yog txiav txim siab cov khoom lag luam kev ruaj ntseg thiab ib puag ncig kev ntsuas tab sis tseem cuam tshuam ncaj qha rau nws cov kev ua tau zoo hauv cov ntawv thov hauv qab. Kev nkag siab tob txog cov txheej txheem no pab kev lag luam ua tiav ob qho tib si zoo thiab kev txhim kho kev ua haujlwm thaum nws hloov pauv ntsuab.

Thawj kauj ruam hauv dej-raws li kev tsim cov xim yog raw khoom pretreatment thiab metering. Cov khoom tseem ceeb muaj xws li dej-raws li resin emulsions, pigments, fillers, additives, thiab deionized dej. Hom thiab cov ntsiab lus ntawm cov resin emulsion txiav txim siab cov yam ntxwv ntawm cov xim zaj duab xis thiab yuav tsum tau xaiv raws li cov khoom muag. Pigments thiab fillers yuav tsum tau dispersed thiab hauv av kom paub meej fineness thiab uniform tis, tsis txhob sib txawv xim thiab tsis txaus lub zog zais. Tag nrho cov ntaub ntawv yuav tsum raug ntsuas kom raug ua ntej nkag mus rau lub ntsiab reactor, tshwj xeeb tshaj yog cov dej piv, uas cuam tshuam ncaj qha rau lub cev viscosity thiab zaj duab xis zoo.

Cov kauj ruam thib ob yog siab - nrawm nrawm thiab sib tsoo. Cov theem no yog txhawm rau rhuav tshem cov pigment agglomerates, kom ntseeg tau tias lawv raug tshem tawm tsis tu ncua hauv cov kua theem. Hauv kev tsim khoom, siab - cov dispersers ceev feem ntau yog siv rau kev sib xyaw ua ke, ua raws li kev sib tsoo txuas ntxiv hauv cov xuab zeb zeb lossis cov hlaws hlaws kom txog rau thaum qhov kev ua tiav tiav. Kev paub qhia tau hais tias cov txheej txheem sib tsoo yuav tsum tau tswj xyuas qhov kub thiab txias los tiv thaiv emulsion demulsification lossis viscosity txawv txav vim muaj kev sib txhuam kub, uas tuaj yeem cuam tshuam rau kev ruaj ntseg tom ntej.

Cov kauj ruam thib peb yog xim sib xyaw thiab kev hloov kho kev ua haujlwm. Tom qab dispersion thiab sib tsoo, lub Cheebtsam yog ntxiv rau cov xim tov tank raws li tus qauv thiab sib tov kom huv si ntawm tsawg ceev. Nyob rau theem no, zaj duab xis- tsim cov khoom siv, defoamers, thickeners, thiab lwm yam khoom siv ntxiv tau ntxiv los ua kom zoo dua qib, txo cov npuas tsim, thiab kho viscosity. Cov tshuaj ntxiv yuav tsum tau muab ntxiv rau hauv cov khoom siv thaum lub sijhawm sib xyaw xim, thiab pH thiab viscosity yuav tsum tau saib xyuas hauv lub sijhawm tiag tiag kom ntseeg tau tias lub kaw lus ruaj khov. Rau ntau-xim lossis cov khoom siv, cov xim sib xws thiab cov qauv sib piv kuj tseem tsim nyog los xyuas kom meej cov khoom sib xws.

Kauj ruam plaub yog pom thiab sau. Txhawm rau kom tsis txhob muaj impurities cuam tshuam rau daim ntawv thov, cov slurry tiav yuav tsum tau mus rau ntau-theem pom, feem ntau siv 100-200 mesh lim kom tshem tawm cov seem coarse. Cov dej lim dej-raws li cov xim nkag mus rau thaj chaw huv huv thiab raug thauj los ntawm cov kav dej kaw kom tiv thaiv kev sib kis thib ob. Cov thawv ntim khoom ntim yuav tsum tau ntxuav ua ntej thiab tshuaj tua kab mob, thiab kaw hauv qab nitrogen purging kom ntev txee lub neej thiab tuav cov yam ntxwv VOC tsawg.

Thaum kawg, kev soj ntsuam zoo thiab tso tawm yuav tsum tau ua. Cov khoom tiav yuav tsum raug kuaj xyuas cov ntsuas tseem ceeb xws li cov tsos, qhov zoo, viscosity, cov ntsiab lus khib nyiab, pH tus nqi, thiab VOC cov ntsiab lus. Daim ntawv thov kev ua tau zoo xws li adhesion, dej tsis kam, thiab huab cua tsis kam kuj tseem raug kuaj raws li cov qauv. Tsuas yog cov khoom tsim nyog tuaj yeem muab khaws cia lossis xa tawm, kom ntseeg tau tias txhua pawg ntawm cov khoom mus txog lub khw ua tau raws li ib puag ncig thiab cov qauv zoo.

Zuag qhia tag nrho, cov dej- cov txheej txheem tsim cov xim yog ua raws li kev ntsuas qhov tseeb, kev sib cais tsis sib xws, kev sib xyaw xim ruaj khov, thiab kev tswj xyuas nruj, nrog rau txhua kauj ruam sib txuas. Qhov no ua kom cov khoom lag luam zoo ib puag ncig thiab tsim lub hauv paus rau nws daim ntawv thov kev ntseeg siab hauv ntau yam txheej xwm txheej txheej. Nrog rau kev qhia txog kev siv tshuab hluav taws xob thiab cov thev naus laus zis digital, cov txheej txheem no xav tias yuav txhim kho kev ua tau zoo thiab sib xws, muab kev txhawb nqa loj rau - nplai ntau lawm ntawm cov xim ntsuab.
