Cov kab ntau lawm txheejyog ib qho tseem ceeb ntawm kev tsim khoom niaj hnub no, nrog nws lub hom phiaj tseem ceeb yog los muab cov khoom ua haujlwm nrog cov xim sib xws, ruaj khov, thiab zoo. Hauv cov txheej txheem no, lub kaw lus sib tov xim ua lub luag haujlwm tseem ceeb "lub plawv". Nws yog ntau tshaj li ib qho cuab yeej sib tov yooj yim; es, nws yog lub hauv paus thev naus laus zis uas ua kom muaj kev ua haujlwm xim ruaj khov, zoo ib yam, cov nqi tsim khoom tswj tau, thiab kev ntws zoo.
Ib lub tshuab sib tov uas tsim los ntawm kev tshawb fawb thiab ua haujlwm tau zoo tuaj yeem txhim kho qhov ua tau zoo ntawm cov kab txheej thiab txhim kho kev sib tw ntawm cov khoom. Ntawm qhov tod tes, yog tias lub kaw lus muaj qhov tsis zoo, nws yuav ua rau muaj ntau yam teeb meem zoo ntawm cov saw hlau, ua rau muaj kev pov tseg ntau ntawm cov khoom siv thiab cov peev txheej.
Yog li ntawd, kev nkag siab zoo txog cov kev cai uascov kab ntau lawm txheejQhov chaw rau ntawm cov tshuab sib tov xim yog lub hauv paus rau kev tsim qauv, kev xaiv cov khoom siv, kev teeb tsa, thiab kev saib xyuas. Cov kev cai no tuaj yeem muab sau ua ke rau hauv rau lub ntsiab lus tseem ceeb: kev sib xyaw ua ke, kev ruaj khov thiab kev sib xws, kev hloov pauv ntawm cov khoom siv, kev yooj yim ua haujlwm thiab kev saib xyuas, kev nyab xeeb thiab kev tiv thaiv ib puag ncig, thiab kev sib koom tes nrog cov kab ntau lawm.
- Kev Sib Xyaws Sib Xws: Lub Hauv Paus ntawm Qhov Zoo thiab Qhov Yuav Tsum Tau Ua Ntej rau Kev Ua Tau Zoo
Kev sib xyaw ua ke yog qhov tseem ceeb tshaj plaws thiab qhov yuav tsum tau ua ntawm lub tshuab sib tov xim, vim nws txiav txim siab ncaj qha rau ob qho tib si tsos thiab qhov zoo ntawm cov xim pleev.
Kev tshem tawm ntawm cov av noo thiab stratification:
Cov xim pleev xim—tshwj xeeb tshaj yog cov uas muaj cov xim pleev xim ntau (xws li cov xim pleev xim hlau lossis cov hmoov pearlescent) lossis cov khoom ntim khov—yeej yuav muaj kev sib xyaw thiab sib cais thaum lub sijhawm khaws cia lossis thaum tso tseg. Yog li ntawd, lub kaw lus sib tov yuav tsum muaj peev xwm txaus los rov ua kom cov khoom sib xyaw uas nyob hauv qab ntawm lub thawv lossis tawg tsis sib npaug thoob plaws hauv lub kaw lus, suav nrog cov xim pleev xim, cov resins, cov kuab tshuaj, thiab cov khoom ntxiv, mus rau hauv ib qho sib tov sib xyaw.
Yuav kom ua tiav qhov no, lub tshuab ua kom sib xyaw yuav tsum muaj peev xwm tsim kom muaj cov dej ntws zoo thiab cov dej ntws shear, tshem tawm cov cheeb tsam tsis sib tov, thiab xyuas kom meej tias cov xim sib xyaw thiab viscosity tseem sib xws ntawm txhua qhov chaw hauv lub tank.
Tswj kev ruaj khov ntawm viscosity:
Qhov viscosity ntawm cov xim pleev muaj feem cuam tshuam rau nws qhov kev ua haujlwm atomization, cov khoom leveling, thiab kev tswj cov thickness ntawm zaj duab xis. Kev sib tov tsis sib xws tuaj yeem ua rau viscosity hloov pauv, uas ua rau cov xim tsis ruaj khov thaum lub sijhawm txau, cov tuab ntawm txheej tsis sib xws, thiab cov qhov tsis zoo xws li tev txiv kab ntxwv thiab sagging. Yog li ntawd, kev sib tov sib xws yog qhov yuav tsum tau ua kom cov xim pleev ruaj khov ob qho tib si hauv tib pawg thiab ntawm ntau pawg.
Kev Txhawb Nqa Kev Ua Kom Muaj Zog thiab Kev Loj Hlob:
Rau cov txheej txheej ob txheej, kev sib tov sib npaug yog qhov tseem ceeb kom ntseeg tau tias cov khoom siv hauv paus thiab cov neeg sawv cev kho tau sib xyaw ua ke kom huv si thiab sai sai kom pib cov tshuaj tiv thaiv. Kev sib tov tsis sib npaug yuav ua rau qhov chaw kho tsis zoo lossis kho ntau dhau, uas tuaj yeem cuam tshuam loj heev rau qhov ceev ntawm cov txheej txheem sib txuas, qhov nyuaj, thiab kev tiv thaiv tshuaj lom neeg. Lub kaw lus sib tov yuav tsum xyuas kom meej tias kev sib tov sib npaug ntawm qib molecular tau ua tiav hauv lub sijhawm maturation (induction).
- Kev Ruaj Ntseg thiab Kev Sib Xws: Kev Paub Tseeb Txog Kev Tsim Khoom Tsis Tu Ncua
Cov kab ntau lawm txheej feem ntau ua haujlwm hauv hom kev tsim khoom tas mus li lossis ntau ntim, uas xav tau lub kaw lus sib tov tsis yog tsuas yog ua kom tiav qhov sib xws thaum pib tab sis kuj tseem yuav tsum tswj hwm kev ua haujlwm ruaj khov thaum lub sijhawm ua haujlwm ntev. Lub zog thiab kev ruaj khov kis tau:
Cov chaw fais fab, suav nrog cov cav thiab cov iav txo qis, yuav tsum xa cov kev ua tau zoo txhim khu kev qha thiab ua haujlwm tau zoo hauv qhov kub thiab txias, av noo, thiab qhov hloov pauv hluav taws xob uas tau teev tseg, kom ntseeg tau tias muaj qhov tso zis tas li ntawm qhov ceev thiab lub zog tig. Qhov kev ruaj khov no yog qhov tseem ceeb los tiv thaiv kev hloov pauv ntawm qhov sib tov los ntawm kev hloov pauv hluav taws xob, uas yuav cuam tshuam rau qhov xwm txheej thiab kev ua haujlwm ntawm cov xim.
Kev Txhim Kho ntawm Cov Qauv Kho Tshuab:
Lub qhov agitator yuav tsum muaj qhov rigidity thiab precision txaus kom ntseeg tau tias muaj qhov tsawg kawg nkaus deflection thaum lub sijhawm thauj khoom, tiv thaiv kev co ntau dhau uas yuav ua rau lub foob lossis lub tank puas tsuaj. Cov khoom tseem ceeb xws li bearings thiab cov foob ntawm lub qhov yuav tsum tsis txhob hnav thiab tsis txhob xeb, nrog rau lub neej tsim ntev, kom ntseeg tau tias kev ua haujlwm ruaj khov thiab tsis muaj teeb meem rau lub sijhawm ntev.
Cov Txheej Txheem Ruaj Khoov:
Lub tshuab yuav tsum muaj peev xwm tswj tau cov kev teeb tsa ua ntej xws li kev sib tov ceev (feem ntau hloov kho tau) thiab lub sijhawm sib tov tas li. Rau cov ntawv thov txheej txheem meej, nws yuav tsum tau nruab nrog lub tshuab nrog kev tswj hwm zaus sib txawv thiab kev saib xyuas lub sijhawm tiag tiag thiab cov txheej txheem tawm tswv yim los pab txhawb kev hloov pauv ntawm qhov ntim xim lossis kev hloov kho me me ntawm cov txheej txheem.
Kev Tswj Kub thiab Txias:
Qee cov txheej pleev xim muaj qhov kub thiab txias, thiab cov cua sov uas tsim los ntawm kev sib tov lossis kev hloov pauv ntawm qhov kub thiab txias ib puag ncig yuav cuam tshuam rau lawv cov viscosity thiab kev ua haujlwm. Yog li ntawd, cov txheej txheem sib tov siab heev yuav tsum tau koom ua ke cov tsho tiv thaiv kub lossis cov kauj sab hauv, ua haujlwm sib koom tes nrog cov txheej txheem sib tov kom tswj tau qhov kub ntawm cov xim hauv lub sijhawm ua haujlwm xav tau.
- Kev Hloov Kho Cov Khoom Siv: Ua Tau Raws Li Qhov Xav Tau ntawm Cov Txheej Txheem Txheej Txheem Ntau YamCov kab ntau lawm txheej txheem niaj hnub no tuaj yeem tswj hwm ntau yam txheej txheem txheej txheem, suav nrog cov xim pleev xim dej, cov txheej txheem ua kom yaj, cov txheej txheem khov kho, cov hmoov txheej slurries, thiab cov txheej txheem UV, txhua tus muaj cov yam ntxwv sib txawv ntawm lub cev thiab tshuaj lom neeg. Yog li ntawd, lub kaw lus sib tov yuav tsum muaj kev hloov kho dav dav ntawm cov khoom siv kom ua tau zoo hauv kev tswj hwm cov txheej txheem sib txawv no.
Kev Sib Tw Nrog Ntau Yam Viscosity:
Txij li cov tshuaj yaj uas muaj viscosity tsawg thiab cov tsho tiv no kom pom tseeb mus rau cov ntaub ntawv uas muaj viscosity siab xws li putties thiab sealants, hom agitator (xws li paddle, turbine, ribbon, lossis anchor hom) thiab lub zog teeb tsa yuav tsum muaj peev xwm npog tag nrho cov viscosity uas koom nrog hauv kev tsim khoom. Rau cov ntaub ntawv uas muaj viscosity siab, lub agitator yuav tsum muaj peev xwm txhawb nqa cov dej ntws loj kom ntseeg tau tias muaj kev sib xyaw zoo thoob plaws hauv lub cev.
-
Tsuas yog los ntawm kev xav txog thiab ua kom tau raws li cov kev cai no xwb, lub kaw lus sib tov uas tsim los yog xaiv zoo thiaj li yuav ua tau lub hauv paus ruaj khov rau kev ua haujlwm ruaj khov ntawm cov kab ntau lawm txheej thiab kev xa khoom zoo. Thaum ua li ntawd, nws ua lub luag haujlwm tseem ceeb hauv kev txhim kho qhov zoo ntawm txheej, txo cov nqi ua haujlwm tag nrho, thiab ua kom muaj kev nyab xeeb thiab kev ua raws li ib puag ncig.
