Functional Powder Coating: Insulated and Conductive Powder Coatings

cov hmoov txheej yog ib yam tshiab ntawm cov kuab tshuaj tsis muaj 100% khoom hmoov txheej. Nws muaj qhov hnyav-dawb, tsis muaj kuab paug, rov ua dua tshiab, ib puag ncig tus phooj ywg, txuag lub zog thiab cov peev txheej, thiab txo qis kev siv zog thiab zaj duab xis txhua yam muaj zog. Cov txheej txheem txheej thiab tsim cov txheej txheej ntawm cov khib nyiab txog li 100%, vim tias lawv tsis siv cov kuab tshuaj, yog li txo cov pa phem ib puag ncig, txuag cov peev txheej thiab cov yam ntxwv rov ua dua tshiab.

cov ua haujlwm hmoov txheej yog ib qho tshwj xeeb muaj nuj nqi, cov ntaub ntawv txheej txheej los muab rau lub hom phiaj tshwj xeeb. Nws tsis tsuas yog tuaj yeem ua lub luag haujlwm tseem ceeb ntawm kev tiv thaiv thiab kho kom zoo nkauj, thiab tseem muab cov khoom siv ntau yam haujlwm tshwj xeeb, suav nrog rwb thaiv tsev, hluav taws xob, hluav taws xob, hluav taws xob, hluav taws xob, hluav taws xob tiv thaiv hluav taws xob thiab lwm yam haujlwm.
Kev loj hlob thiab kev tsim cov hmoov txheej ua haujlwm tau nyuam qhuav pib, tseem ua lag luam nyob deb nrog txawv teb chaws qib siab. Feem ntau siv cov hmoov coatings generally muaj cov nram qab no hom:

Insulated hmoov txheej

Rwb thaiv tsev hmoov txheej Ib txheej tshwj xeeb yog siv rau cov motors, cov khoom siv hluav taws xob thiab hluav taws xob, ntxiv rau kev tiv thaiv cov noob.ral hmoov txheej, cov khoom zoo nkauj, tab sis kuj muaj cov khoom siv hluav taws xob zoo.

Epoxy resins yog cov ntaub ntawv zoo heev rau kev tsim cov hmoov insulating.Los ntawm kev hloov hom curing tus neeg saib xyuas, los yog ntxiv ib qho kev hloov kho tshwj xeeb thiab nrog cov rwb thaiv tsev zoo thiab kub tsis kam ntawm cov muab tub lim los kho tus nqi kho, tau los ntawm cov mos mos, hloov tau, tawv heev. , hnav ntau yam txheej txheem kom hloov mus rau qhov sib txawv rwb thaiv tsev. Nyob rau hauv xyoo tas los no, nrog rau kev zam ntawm epoxy hmoov txheej, polyurethane hmoov txheej, hmoov txheej ntawm polyimide, acrylic hmoov txheej, thiab lwm yam kuj tseem niaj hnub tsim thiab siv.

Conductive hmoov txheej

Lub conductive hmoov txheej yog siv rau cov uas tsis yog-conductive substrate, thiaj li hais tias nws muaj tej yam conduction tam sim no thiab tshem tawm ntawm lub electrostatic muaj peev xwm ntawm functional coatings. Cov txheej txheem zoo li no feem ntau yog ob hom: hom sib xyaw thiab hom khoom siv

Blended hmoov txheej yog insulating polymer txheej zaj duab xis tsim cov ntaub ntawv, tsim nyob rau hauv uas kev koom ua ke ntawm conductive fillers. Conductive muab tub lim, hlau hmoov, xws li nyiaj, npib tsib xee, zinc, txhuas, thiab lwm yam .; tsis-metallic hmoov, xws li graphite, carbon dub; hlau oxides xws li zinc oxide, antimony oxide. Lub binder Xaiv cov vinyl resins, polyester resins, polyamide thiab epoxy resin.

Lub intrinsic conductive polymer yog lub polymer nws tus kheej yog conductive, tam sim no chav kawm ntawm polymer yog tseem nyob rau hauv txoj kev xav thiab kev tshawb fawb theem, tsis muaj kev siv tswv yim.

Anticorrosive hmoov txheej

Tam sim no siv cov txheej txheem no epoxy phenolic anti-corrosion hmoov txheej nrog epoxy resin thiab phenolic resin-raws li zaj duab xis-tsim tshuaj, ob qho tib si hla kev sib txuas ntawm txheej. Hom xim no siv nyob rau hauv epoxy yog noobrally siv nyob rau hauv cov polymer hom ntawm molecular hnyav ntawm 1400,2900 thiab 3570. Epoxy resin nws tus kheej, adhesion, yooj thiab alkali tsis kam thiab zoo, thiab phenolic resin nrog zoo heev acid, hnyav, kub, humidity txias kev ua tau zoo yog ua ke los ua anti-corrosion. cov ntaub ntawv zoo tagnrho hom. Tsis muaj zog reactivity ntawm epoxy thiab phenolic resin txheej zaj duab xis curing kub yuav tsum tau nyob rau hauv ntau dua tej yam kev mob, los ntawm kev ntxiv tus nqi tsim nyog ntawm imidazole catalyst kom txo qhov kub thiab txias.

Thaum tshav kub kub resistant hmoov txheej

Thaum tshav kub kub resistant hmoov txheej tuaj yeem tiv taus qhov kub siab tshaj 200 ℃, zaj duab xis zoo, thiab ua rau cov khoom tiv thaiv hauv qhov kub thiab txias kom ua haujlwm zoo

Los ntawm cov txheej txheem nyob rau hauv cov nqe lus ntawm polymer thermal stability, tshav kub tsis kam ntawm polymer nyob ntawm nws cov qauv molecular. Yog li, nce lub zog ntawm kev sib cuam tshuam los ntawm kev qhia txog cov pawg loj lossis ntau dua polar sab hauv cov saw tseem ceeb, yog li txhim kho thermal stability ntawm cov polymer. Lwm txoj hauv kev yog txhawm rau txhim kho cov cua sov ntawm cov hmoov txheej los ntawm kev ntxiv cov xim kub-resistant thiab muab tso rau hauv cov polymer. Feem ntau siv nyob rau hauv pigments, muab tub lim yog txhuas hmoov, mica hmoov, stainless hlau hmoov, cadmium hmoov, silica. Tam sim no, lub tshav kub-resistant hmoov txheej tseem yog silicone hmoov txheej raws li. Qhov txheej txheem no yog lub ntsiab lus tseem ceeb ntawm kev tshawb fawb yav tom ntej kev tsim kho muaj peev xwm ntawm qhov kub siab dua thiab muaj cov yeeb yaj kiab zoo tsim thiab kev tsim kho ntawm high-temperature resin raws li cov khoom siv ntawm cov txheej txheem kub-resistant, nrog rau kev tshawb fawb tuaj yeem txhim kho kev ua tau zoo ntawm ntau yam hauv paus. cov khoom nyob rau hauv kub kub tej yam kev mob pigments, fillers, tshiab ntau yam.

Kho kom zoo nkauj hmoov txheej

Hniav hmoov txheej yog tus cwj pwm los ntawm txheej txheej ntawm qhov pom tseeb ntawm cov qauv rau cov khoom txheej yog qhov zoo nkauj thiab muaj yeeb yuj. Cov hmoov txheej siv nws cov yam ntxwv melting ntawm kev ntxhib los mos, cov qauv duab thiab qhov ntau thiab tsawg, daim ntawv qhia sib xyaw, cov txheej txheem kev npaj thiab cov hmoov particle loj.

Formula ua ke ntawm hluavtaws cob, curing agents, leveling agents, pigments thiab ntau yam additives, yog qhov tseem ceeb hauv kev tsim cov qauv. Tsim txoj hauv kev kom muaj cov tswv yim tseem ceeb hauv qab no:

1. siv cov polymers tsis sib xws los tsim lub xeev ntws, tsim ntawm peb sab kev nkag siab ntawm cov qauv;
2. txawv curing tus nqi ntawm tus neeg sawv cev curing, vim qhov sib txawv ntawm leveling ceev los tsim ib tug tsim wrinkles;
3. Nrog cov fillers sib txawv, ua rau cov hmoov txheej txheej, gloss thiab xim sib txawv, ua rau cov nyhuv zoo nkauj;
4. sib txawv granularity thiab sib txawv ntxoov ntxoo ntawm cov xim hlau xim nyob rau hauv txheej nyob rau hauv ib txoj hauj lwm sib txawv, cov ces kaum sib txawv, ua rau qhov sib txawv ntawm gloss thiab xim.

Nplaim retardant hmoov txheej

High polymer nplaim taws retardant txwv, los txhim kho cov nplaim retardancy ntawm polymers yog cov tswv yim tseem ceeb nyob rau hauv ntau qhov chaw ntawm daim ntawv thov. Cov nplaim retardant hmoov txheej rau hluav taws thiab hluav taws-retardant rwb thaiv tsev muaj nuj nqi. Nrog rau txoj kev loj hlob sai ntawm cov khoom siv hluav taws xob niaj hnub thiab cov khoom siv hauv kev lag luam, cov kev xav tau ntawm cov txheej txheem hluav taws xob hluav taws xob yog qhov nrawm dua. Lub ntsiab ntau yam ntawm cov txheej no yog epoxy hmoov txheej.

Kev ua haujlwm hmoov txheej yog ib yam tshwj xeeb ntawm cov khoom siv ua haujlwm ua lub luag haujlwm tseem ceeb hauv ntau thaj chaw ntawm kev tshawb fawb thiab thev naus laus zis, kev tiv thaiv, kev lag luam thiab kev ua liaj ua teb.ral. Ntawm qhov sib txawv nrog cov teb chaws txawv teb chaws nyob rau hauv xws li cov khoom tsim loj, peb yuav tsum siv zog los tsim thiab tsim kom muaj kev ua haujlwm zoo ntawm kev ua haujlwm zoo dua qub.rall kev ua tau zoo, tus nqi qis, pleev xim rau cov hmoov txheej ua haujlwm kom tau raws li cov kev xav tau ntawm kev lag luam hauv lub tebchaws.
