Kev soj ntsuam ntawm electrostatic hmoov txau tshuab cov qauv thiab kev lag luam kev lag luam

Electrostatic hmoov txau tshuab, feem ntau hu ua hmoov txau, yog cov txheej txheem siab heev uas siv dav hauv kev kho hlau saum npoo. Nws cov tub ntxhais kawm tsis yog txheej txheej nkaus xwb, tab sis cov txheej txheem kev thov dav dav suav nrog physics, cov ntaub ntawv tshawb fawb thiab engineering. Txhawm rau kom nkag siab txog cov thev naus laus zis no, peb tuaj yeem pib los ntawm qhov tshwm sim zoo li tsis sib xws: Vim li cas cov hmoov qhuav tuaj yeem sib npaug thiab khov kho rau ntawm qhov chaw ua haujlwm zoo li kua xim? Cov lus teb rau lo lus nug no taw qhia ncaj qha rau cov nyhuv electrostatic adsorption, lub hauv paus pob zeb ntawm electrostatic hmoov txau tshuab.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Cov hmoov hmoov uas tau them yog tsav los ntawm Coulomb quab yuam nyob rau hauv electrostatic teb thiab ya mus rau hauv av workpiece raws li cov kev taw qhia ntawm cov hluav taws xob teb kab. Thawj zaug adsorbed hmoov txheej yuav tsim ib txheej txheej insulating, tab sis vim tias cov hmoov txheej yog xoob thiab ntxeem tau, lub zog electrostatic tseem tuaj yeem nkag mus. Cov hmoov tom qab txuas ntxiv mus rau adsorbed kom txog thaum lawv ncav cuag ib lub thickness. Tus nqi saum npoo thiab hmoov nqi sib tw, lub zog adsorption tsis muaj zog, thiab cov txheej txheem tso nyiaj yuav tsum nres. Qhov no yog hu ua "self-limiting effect." Cov yam ntxwv no ua rau nws yooj yim kom tau txais cov tuab tuab ntawm cov hmoov txheej ntawm cov chaw tiaj tus.

Tom qab cov hmoov yog sib npaug, lub workpiece nkag mus rau theem solidification. Curing ncu feem ntau muab qhov kub thiab txias ntawm 180℃txog 200 degree. Thaum lub sijhawm txheej txheem no, cov hmoov nplej hloov pauv los ntawm lub xeev iav mus rau lub xeev cov dej khov, thiab dhau los ntawm kev hloov pauv ntawm lub cev xws li melting, leveling, thiab ntub dej ntawm lub workpiece. Subsequently, a cross-linking chemical reaction occurs between the resin and the curing agent to form a dense, continuous, and solid paint film. Cov kauj ruam no ua kom tiav qhov kev hloov pauv zaum kawg ntawm cov txheej txheem los ntawm lub cev adsorption mus rau cov tshuaj sib txuas, muab nws cov khoom zoo heev thiab kev tiv thaiv corrosion.

Tsis yog txhua cov hmoov tuaj yeem siv rau hauv cov txheej txheem no. Electrostatic hmoov txheej yog tsim tshwj xeeb thiab lawv cov khoom xyaw feem ntau suav nrog cov resins (xws li epoxy, polyester), curing agents, pigments, leveling agents thiab additives. Cov resin txiav txim siab cov yam ntxwv ntawm cov txheej txheem, xws li huab cua tsis kam lossis tshuaj lom neeg ua haujlwm; tus neeg sawv cev kho kom ntseeg tau tias hla - txuas cov tshuaj tiv thaiv tshwm sim thaum cua sov; thiab tus neeg sawv cev theem pab cov xim molten sib kis sib npaug. Cov khoom xyaw no yuav tsum ua kom tau raws li qhov xav tau xws li muaj peev xwm ua tau electrostaticized, yaj, theem thiab solidify ntawm qhov kub thiab txias, thiab nyob twj ywm lub cev thiab tshuaj ruaj khov thaum lub sij hawm cia.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Ntau qhov zoo ntawm electrostatic hmoov txau tshuab yog los ntawm nws cov hauv paus ntsiab lus. Kev siv cov khoom siv siab yog ncaj qha los ntawm kev taw qhia kev nyiam ntawm electrostatic teb thiab cov hmoov zoo rov qab ua haujlwm. Cov txheej txheem txheej txheem zoo heev vim tias cov txheej txheem kho ua tiav tag nrho - txuas network polymer qauv, thiab txheej txheej tuaj yeem ncav cuag tuab tuab (feem ntau 50-}150 microns) nrog rau ib qho tshuaj tsuag, tsis tas yuav tsum muaj ntau txheej txheej. Environmental friendliness yog reflected nyob rau hauv lub fact tias tag nrho cov txheej txheem yuav luag tsis muaj volatile organic tebchaw, vim hmoov coatings tsis muaj organic solvents.

Txawm li cas los xij, thev naus laus zis kuj muaj kev txwv lub cev. Piv txwv li, lub workpiece yuav tsum muaj peev xwm tiv taus qhov kub thiab txias ntawm ib ncig ntawm 200 degree, uas tsis suav cov cua sov- cov ntaub ntawv rhiab heev xws li yas thiab ntoo. Lub workpiece yuav tsum yog ib tug zoo conductor ntawm hluav taws xob los xyuas kom meej zoo grounding. Rau cov khoom uas tsis yog -conductive, yuav tsum tau pretreatment deg (xws li spraying conductive primer), uas ua rau kom cov complexity ntawm cov txheej txheem.

Nyob rau hauv lub tshuab kuaj kab mob, lub siab- cov hmoov txheej zoo nthuav tawm cov txheej txheem sib xws, ntom ntom ntuag, thiab cov resin thiab cov xim yog sib xyaw ua ke. Rau ntau cov kua coatings, tshwj xeeb tshaj yog hnyav-raws li txheej txheej, cov txheej txheem tsim zaj duab xis yog nrog los ntawm cov kuab tshuaj evaporation, uas tuaj yeem yooj yim tawm hauv cov pores hauv cov duab los yog ua rau cov xim tsis sib xws. Hmoov txheej kuj feem ntau muaj tus ntoo khaub lig siab dua -txuas txuas, uas yog cov lus piav qhia microchemical rau lawv cov kev tiv thaiv ntau dua rau khawb thiab xeb.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Raws li cov hauv paus ntsiab lus saum toj no, daim ntawv thov ntawm cov cuab yeej no tau nthuav dav los ntawm cov khoom siv hauv tsev, rooj tog zaum, thiab cov khoom siv hauv tsev mus rau cov khoom siv tsheb, cov chaw sab nraum zoov, cov txheej txheem ua haujlwm rau cov khoom siv hluav taws xob, thiab lwm yam. Lub tsheb log thiab lub cav chassis tau txais txiaj ntsig los ntawm lawv cov khoom tiv thaiv siab - corrosion; qee cov khoom siv hluav taws xob siv cov hmoov coatings nrog cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob kom ua tiav electromagnetic shielding lossis rwb thaiv tsev tiv thaiv. Nyob rau hauv lub zog thiab hluav taws xob teb, nyob rau hauv daim ntawv thov scenarios xws li rwb thaiv tsev txheej Busbar, Electroplating thiab hmoov txheej Busbar, thiab EV Busbar Powder Txheej, hmoov txau tshuab muab busbars nrog txhim khu kev qha rwb thaiv tsev tiv thaiv thiab ib puag ncig corrosion kuj.

 

Technology evolution ze ze ntawm lub hauv paus ntsiab lus. Txoj kev loj hlob ntawm qis-kub curing hmoov aims kom tawg los ntawm cov kev txwv ntawm tshav kub-sensitive substrates; finer hmoov particle loj tswj pab ua kom cov txheej nyias nyias thiab smoother nto; lub ntse tswj system cia li optimizes tsis kam nrog txawv workpieces los ntawm kev saib xyuas tam sim no, voltage thiab hmoov txaus nyob rau hauv lub sij hawm. Cov lus qhia kev tshawb fawb yav tom ntej suav nrog kev txhim kho cov hmoov zoo dua cov txheej txheem, cov tshuaj electrostatic txau rau cov khoom tsis yog -cov khoom siv, thiab cov khoom siv tshiab uas txo qis kev siv hluav taws xob ntxiv.
