Cov cuab yeej tshuaj

Raws li cov qauv tshuaj sib txawv, qhov no zoo ntawm cov neeg saib xyuas theem muaj peb pawg loj: Acrylic acid, organic silicon thiab fluorocarbon. Tus neeg sawv cev qib lev yog ib feem uas siv ib couxiliary txheej tus neeg sawv cev, uas tuaj yeem ua rau txheej txheej du, du thiab unfiform zaj duab xis nyob rau hauv cov txheej txheem ntawm kev ziab. Tuaj yeem txo cov npoo av ntawm cov kua hauv cov kua, txhim kho nws cov txheej txheem txheej thiab kev sib txawv ntawm cov chav ua yeeb yam. Nws tuaj yeem txhim kho cov kev sib xyaw ntawm cov tshuaj ua tiav, txo cov peev xwm ntawm cov cim thaum txhuam hniav, thiab ua kom cov zaj duab xis hnav thiab ntuj. Tsuas yog surfactants, organic kuab tshuaj thiab lwm yam. Muaj ntau ntau yam ntawm tus neeg sawv cev theem leveling, thiab cov neeg saib xyuas theem theem uas siv nyob rau hauv cov txheej txheem sib txawv tsis zoo ib yam. High boiling taw qhia cov kuab tshuaj lossis butyl cellulose tuaj yeem siv rau hauv cov kuab tshuaj tiav. Hauv dej - raws li cov neeg sawv cev nrog surfactants lossis polyacrylic acid, carboxymethyl cellulose

Khoom Taw Qhia thiab Nta

Leveling cov neeg sawv cev yog cov muab faib kom dav rau hauv ob pawg. Ib qho yog los ntawm kev kho cov yeeb yaj kiab viscosity thiab leveling sij hawm ua haujlwm, xws li isoporone, salcetone cawv, salvesso150; Lwm tus yog los ntawm kev kho cov zaj duab xis saum cov khoom ua haujlwm, cov tib neeg dav dav hais tias leveling tus neeg sawv cev feem ntau yog hais txog hom leveling leveling. Qhov no zoo ntawm tus neeg saib xyuas theem mus rau saum npoo ntawm zaj duab xis los ntawm kev sib raug zoo ntawm cov yeeb yaj kiab xws li interfacial nro, thiab ua rau zaj duab xis tau txais kev ua tau zoo.

kev siv

Lub luag haujlwm tseem ceeb ntawm cov txheej yog kho kom zoo nkauj thiab kev tiv thaiv, yog tias muaj kev puas ntsoog, tsis tsuas yog cuam tshuam rau cov tsos, tab sis kuj ua rau kev tiv thaiv kev tiv thaiv. Xws li kev tsim ntawm shrinkage tshwm sim los ntawm cov yeeb yaj kiab thickness tsis txaus, tsim ntawm pinholes yuav ua rau zaj duab xis tsis kam, cov no yuav txo cov kev tiv thaiv zaj duab xis. Nyob rau hauv cov txheej txheem ntawm txheej kev tsim kho thiab kev hloov pauv ntawm lub cev, yuav muaj qee yam kev hloov pauv, cov kev hloov pauv no cuam tshuam rau cov ntws thiab nce qib ntawm txheej.
Tom qab txheej yog thov, cov kev cuam tshuam tshiab yuav tshwm sim, feem ntau cov kua / cov khoom sib tshuam ntawm cov txheej thiab cov kua / roj sib tshuam ntawm cov txheej thiab huab cua. Yog tias qhov kev cuam tshuam interfacial ntawm cov kua / cov khoom sib tshuam ntawm cov txheej thiab ntau dua li cov txheej txheem tseem ceeb ntawm lub substrate, uas yuav ua rau muaj kev tsis xws luag xws li Fisheye thiab Shrinkage qhov.
Lub evaporation ntawm cov kuab tshuaj thaum lub sijhawm ua kom qhuav yuav ua rau kub thiab kub thiab sab hauv ntawm zaj duab xis. Cov kev sib txawv no hauv kev lem ua rau cov lus tawm mus rau hauv zaj duab xis, tsim qhov thiaj li hu ua Benard Vortex. Benard Vortex ua rau cov txiv kab ntxwv tev; Hauv cov kab ke nrog ntau tshaj ib qho xim, yog tias muaj qee qhov sib txawv ntawm cov xim xim, cov khoom siv Benard yuav ua rau cov xim ntab thiab cov plaub hau yuav ua rau cov kab lo lo ntxhuav.
Cov txheej txheem ziab ntawm cov yeeb yaj kiab pleev xim rau qee zaum, ntau lawm ua rau cov khoom lag luam ntawm cov yeeb yaj kiab. Piv txwv li, nyob rau hauv ib tug ntoo khaub lig-txuas cov txheej txheem sib txuas, qhov twg cov qauv muaj ntau dua ib qho chaw uas tsis tshua muaj zog ntawm cov txheej txheem kom qhuav ntawm cov xim pleev xim. Tsis tas li ntawd, nyob rau hauv lub formulation muaj surfactant, yog tias surfactant hloov pauv hloov pauv rau solubility, lossis kev tsim cov khoom tsis sib xws, tseem yuav tsim saum npoo nro. Cov no tuaj yeem ua rau kev tsim cov qhov ntsws uas shrinkage.
Nyob rau hauv cov txheej txheem ntawm txheej tsim thiab ua yeeb yaj kiab tsim, nws kuj tseem tuaj yeem ua rau shrinkage qhov, fisheye thiab lwm yam tsis xws luag. Cov kuab paug no feem ntau yog los ntawm huab cua, kev siv cov cuab yeej, plua plav roj, plua plav, xim huab, dej vapor, thiab lwm yam.
Cov yam ntxwv ntawm cov xim nws tus kheej, xws li kev ua haujlwm viscosity, lub sijhawm qhuav, thiab lwm yam, kuj tseem muaj kev cuam tshuam loj ntawm theem kawg ntawm cov xim pleev xim. Kev siv viscosity dhau heev thiab luv luv heev kom qhuav lub sijhawm yuav feem ntau ua cov khoom tsis zoo.
Yog li ntawd, nws yog ib qho tsim nyog los ntxiv cov neeg saib xyuas qib theem, dhau los ntawm kev hloov pauv ntawm qee qhov kev hloov pauv thiab cov khoom sib hloov kho kom haum, txhawm rau pab pleev xim tau zoo.

Pob Thiab Thauj

B. Cov khoom lag luam no tuaj yeem siv, 25kg, 200kg, 1000kg Barrels.
C. Cov khw ntim khoom txias rau hauv qhov chaw txias, qhuav thiab muaj qhov cua nyob sab hauv tsev. Cov ntim yuav tsum kaw kom nruj nreem tom qab siv ua ntej siv.
D. Cov khoom no yuav tsum tau muab kaw zoo thaum caij tsheb thauj mus los kom tiv thaiv noo noo, muaj zog alkali, nag, nag los ntawm kev sib xyaw.
