Leveling tus neeg sawv cev
chemical khoom
Raws li cov qauv tshuaj sib txawv, tus neeg sawv cev zoo li no muaj peb pawg tseem ceeb: acrylic acid, organic silicon thiab fluorocarbon.Leveling tus neeg sawv cev yog ib qho uas feem ntau siv cov txheej txheem txheej txheej, uas tuaj yeem ua rau cov txheej txheem ua ib zaj duab xis du, du thiab zoo ib yam hauv cov txheej txheem ziab.Ua tau zoo txo qhov nro ntawm cov kua txheej txheej, txhim kho nws cov qib thiab sib xws ntawm cov chav kawm ntawm cov khoom.Nws tuaj yeem txhim kho qhov permeability ntawm cov txheej txheem tiav, txo qhov muaj peev xwm ntawm cov pob thiab cov cim thaum txhuam, nce qhov kev pab cuam, thiab ua rau cov yeeb yaj kiab zoo ib yam thiab ntuj.Feem ntau surfactants, organic solvents thiab lwm yam.Muaj ntau ntau yam ntawm tus neeg sawv cev leveling, thiab cov hom ntawm tus neeg sawv cev siv hauv cov txheej txheem sib txawv tsis zoo ib yam.High boiling point solvents los yog butyl cellulose tuaj yeem siv rau hauv cov kuab tshuaj ua tiav.Hauv dej - raws li tus neeg sawv cev tiav nrog cov surfactants lossis polyacrylic acid, carboxymethyl cellulose
Khoom taw qhia thiab nta
Leveling agents tau muab faib ua ob pawg.Ib qho yog los ntawm kev kho cov yeeb yaj kiab viscosity thiab leveling lub sij hawm mus ua hauj lwm, hom leveling tus neeg sawv cev no feem ntau yog ib co kub boiling point organic solvents los yog mix, xws li isoporone, diacetone cawv, Solvesso150;Lwm qhov yog los ntawm kev kho cov yeeb yaj kiab saum npoo av kom ua haujlwm, cov neeg sawv cev hais tias tus neeg saib xyuas qib feem ntau yog hais txog cov neeg sawv cev zoo li no.Hom QHOV CHAW UA HAUJ LWM no tsiv mus rau saum npoo ntawm zaj duab xis los ntawm kev sib raug zoo sib xws, cuam tshuam rau cov khoom ntawm cov yeeb yaj kiab xws li INTERfacial nro, thiab ua rau cov yeeb yaj kiab tau zoo.
siv
Lub luag haujlwm tseem ceeb ntawm txheej yog kev kho kom zoo nkauj thiab kev tiv thaiv, yog tias muaj qhov tsis xws luag thiab qib theem, tsis tsuas yog cuam tshuam rau cov tsos, tab sis kuj ua rau kev tiv thaiv kev ua haujlwm.Xws li qhov tsim ntawm shrinkage tshwm sim los ntawm cov yeeb yaj kiab thickness tsis txaus, tsim cov pinholes yuav ua rau cov yeeb yaj kiab tsis txuas ntxiv, cov no yuav txo cov yeeb yaj kiab tiv thaiv.Nyob rau hauv cov txheej txheem ntawm txheej txheej thiab tsim zaj duab xis, yuav muaj qee qhov kev hloov pauv ntawm lub cev thiab tshuaj lom neeg, cov kev hloov pauv no thiab qhov xwm txheej ntawm txheej nws tus kheej, yuav cuam tshuam rau qhov ntws thiab qib ntawm txheej txheej.
Tom qab txheej txheej yog thov, cov kev sib tshuam tshiab yuav tshwm sim, feem ntau cov kua / khoom sib txuas ntawm cov txheej thiab cov substrate thiab cov kua / roj cuam tshuam ntawm txheej thiab huab cua.Yog hais tias INTERfacial nro ntawm cov kua / khoom sib cuam tshuam ntawm cov txheej thiab cov substrate yog siab tshaj qhov tseem ceeb ntawm qhov nro ntawm lub substrate, lub txheej yuav tsis muaj peev xwm kis tau rau ntawm lub substrate, uas yuav ib txwm ua rau leveling defects xws li fisheye thiab shrinkage. qhov.
EVAPORATION OF SOLVENT Thaum lub sij hawm ziab txheej txheem ntawm zaj duab xis yuav ua rau qhov kub thiab txias, qhov ntom ntom thiab qhov sib txawv ntawm qhov sib txawv ntawm qhov saum npoo thiab sab hauv ntawm zaj duab xis.Cov kev sib txawv no ua rau muaj kev ntxhov siab nyob rau hauv zaj duab xis, ua rau lub npe hu ua Benard vortex.Benard vortex ua rau txiv kab ntxwv tev;Hauv cov tshuab uas muaj ntau tshaj ib cov xim, yog tias muaj qee qhov sib txawv ntawm kev txav ntawm cov xim xim, Benard vortex kuj tseem yuav ua rau cov xim ntab thiab cov plaub hau, thiab kev tsim kho ntsug yuav ua rau cov kab lo lo ntxhuav.
Cov txheej txheem ziab khaub ncaws ntawm cov xim pleev xim rau qee lub sij hawm tsim qee cov khoom tsis sib haum COLLOIDAL, kev tsim cov khoom tsis zoo hauv cov COLLOIDAL yuav ua rau kev tsim ntawm qhov nro gradient, feem ntau ua rau kev tsim cov qhov shrinkage hauv cov xim zaj duab xis.Piv txwv li, nyob rau hauv ib tug CROSS-LINKED CONSOLIDATION SYSTEM, qhov twg cov formulation muaj ntau tshaj ib tug RESIN, cov tsawg soluble resin yuav tsim insoluble colloidal hais raws li cov kuab tshuaj volatilizes thaum lub sij hawm ziab txheej txheem ntawm cov xim zaj duab xis.Nyob rau hauv tas li ntawd, nyob rau hauv lub formulation muaj surfactant, yog hais tias tus surfactant tsis sib haum nrog lub system, los yog nyob rau hauv lub qhuav txheej txheem nrog lub volatilization ntawm cov kuab tshuaj, nws concentration hloov ua rau cov kev hloov nyob rau hauv solubility, tsim incompatible droplets, kuj yuav tsim nto. nruj.Cov no tuaj yeem ua rau tsim cov qhov shrinkage.
Nyob rau hauv cov txheej txheem ntawm txheej txheej thiab tsim cov yeeb yaj kiab, yog tias muaj cov pa phem sab nraud, nws kuj tseem tuaj yeem ua rau lub qhov shrinkage, fisheye thiab lwm yam tsis xws luag.Cov pa phem no feem ntau yog los ntawm huab cua, cov cuab yeej tsim kho thiab cov roj substrate, hmoov av, xim pos huab, dej vapor, thiab lwm yam.
Cov khoom ntawm cov xim nws tus kheej, xws li kev tsim kho viscosity, lub sij hawm ziab, thiab lwm yam, kuj yuav muaj kev cuam tshuam loj rau qhov kawg theem ntawm cov xim zaj duab xis.Kev tsim kho siab dhau viscosity thiab lub sijhawm ziab luv luv yuav feem ntau ua rau qhov chaw tsis zoo.
Yog li ntawd, nws yog ib qho tsim nyog yuav tau ntxiv tus neeg sawv cev theem, los ntawm cov txheej txheem ntawm kev tsim kho thiab kev tsim cov yeeb yaj kiab ntawm qee qhov kev hloov pauv thiab txheej txheej los hloov kho, pab cov xim kom tau zoo leveling.
pob thiab thauj
B. Cov khoom no tuaj yeem siv tau, 25KG, 200KG, 1000KG BARRELS.
C. Khaws ntim rau hauv qhov chaw txias, qhuav thiab qhov cua nyob hauv tsev.Cov thawv ntim khoom yuav tsum tau muab kaw kom nruj tom qab siv txhua zaus ua ntej siv.
D. Cov khoom no yuav tsum raug kaw kom zoo thaum lub sijhawm thauj mus los kom tsis txhob ya raws, muaj zog alkali thiab acid, nag thiab lwm yam impurities los ntawm kev sib xyaw.
