Muaj ntau lub npe sib txawv nyob ntawm seb hom xim siv, piv txwv li, lub tsho tiv no yog hu ua primer coat, thiab lub tsho tiv no yog hu ua lub tsho tiav.Feem ntau, cov txheej tau los ntawm txheej yog nyias nyias, txog 20 ~ 50 microns, thiab cov txheej txheej tuab tuaj yeem tau txais txheej txheej nrog lub thickness ntau tshaj 1 hli ib zaug.
Nws yog ib txheej nyias ntawm cov yas coated rau hlau, ntaub, yas thiab lwm yam substrates rau kev tiv thaiv, rwb thaiv tsev, kho kom zoo nkauj thiab lwm yam.
Kub kub hluav taws xob rwb thaiv tsev txheej
Tus neeg xyuas pib ua los ntawm tooj liab, txhuas thiab lwm yam hlau yog them nrog insulating xim lossis yas, roj hmab thiab lwm yam insulating sheaths.Txawm li cas los xij, insulating xim, yas thiab roj hmab yog ntshai ntawm qhov kub thiab txias.Feem ntau, yog tias qhov kub siab tshaj 200 ℃, lawv yuav sib sau ua ke thiab poob lawv cov khoom insulating.Thiab ntau cov xov hlau yuav tsum ua haujlwm nyob rau hauv qhov kub thiab txias, peb yuav ua li cas?Yog lawm, cia cov hluav taws kub kub rwb thaiv tsev txheej txheej pab.Qhov txheej txheem no yog txheej txheem ceramic.Ntxiv nrog rau kev tswj xyuas cov hluav taws xob rwb thaiv tsev ua haujlwm ntawm qhov kub thiab txias, nws tuaj yeem ua tau zoo "sib koom" nrog cov hlau hlau kom ua tiav "seamless".Koj tuaj yeem qhwv cov hlau xya zaus thiab yim zaug, thiab lawv yuav tsis sib cais.Cov txheej no yog tuab heev.Thaum koj siv nws, ob lub xov hlau uas muaj qhov sib txawv loj yuav sib tsoo yam tsis muaj kev puas tsuaj.
Kub kub hluav taws xob rwb thaiv tsev txheej tuaj yeem muab faib ua ntau hom raws li lawv cov tshuaj muaj pes tsawg leeg.Piv txwv li, boron nitride los yog txhuas oxide los yog tooj liab fluoride txheej ntawm graphite conductor tseem muaj hluav taws xob rwb thaiv tsev zoo ntawm 400 ℃.Cov enamel ntawm cov hlau hlau ncav cuag 700 ℃, phosphate raws li inorganic binder txheej nce mus txog 1000 ℃, thiab cov plasma sprayed aluminium oxide txheej nce mus txog 1300 ℃, tag nrho cov uas tseem muaj cov hluav taws xob rwb thaiv tsev zoo.
Kub kub hluav taws xob insulating txheej tau siv dav hauv hluav taws xob, lub cev muaj zog, cov khoom siv hluav taws xob, hluav taws xob, aviation, atomic zog, chaw siv tshuab, thiab lwm yam.

Raws li FNLONGO qhov kev faib tawm ntawm thermal spraying coatings, coatings tuaj yeem muab faib ua:
1. Hnav resistant txheej
Nws muaj xws li nplaum hnav resistant, nto qaug zog hnav resistant thiab yaig resistant coatings.Qee qhov xwm txheej, muaj ob hom kev hnav khaub ncaws tiv thaiv: tsis tshua muaj kub (<538 ℃) hnav cov coatings resistant thiab kub siab (538 ~ 843 ℃) hnav resistant coatings.
2. Thaum tshav kub kub resistant thiab oxidation resistant txheej
Cov txheej txheem muaj xws li cov txheej txheem txheej txheem kub kub (xws li oxidation cua, corrosive gas, yaig thiab thermal barrier saum 843 ℃) thiab molten hlau txheej txheem (xws li molten zinc, molten aluminium, molten hlau thiab hlau, thiab molten tooj liab).
3. Anti atmospheric thiab immersion corrosion txheej
Atmospheric corrosion muaj xws li corrosion tshwm sim los ntawm industrial cua, ntsev cua thiab teb cua;Immersion corrosion muaj xws li corrosion tshwm sim los ntawm haus dej tshiab, tsis haus dej tshiab, dej tshiab, dej ntsev, chemistry thiab zaub mov ua.
4. conductivity thiab tiv thaiv txheej
Cov txheej no yog siv rau conductivity, kuj thiab shielding.
5. Rov qab txheej txheej txheej
Cov txheej no yog siv rau cov hlau raws (machinable thiab grindable carbon steel thiab corrosion resistant steel) thiab non-ferrous hlau (nickel, cobalt, tooj liab, txhuas, titanium thiab lawv alloys).
6. Gap tswj txheej rau cov khoom siv tshuab
Cov txheej no yog grindable.
7. Tshuaj tiv thaiv txheej
Tshuaj corrosion muaj xws li corrosion ntawm ntau yam acids, alkalis, ntsev, ntau yam inorganic tshuaj thiab ntau yam organic chemical media.
Ntawm cov txheej txheem saum toj no, txheej hnav-tiv taus, tshav kub resistant thiab oxidation resistant txheej thiab tshuaj corrosion resistant txheej yog ze ze rau kev lag luam metallurgical ntau lawm.

Piv txwv li, pebPC thiab PMMA khoomfeem ntau siv txheej.
Ntau cov khoom PC thiab PMMA muaj qhov yuav tsum tau muaj qhov siab, uas feem ntau yog qhov yuav tsum tau kho qhov muag.Yog li ntawd, cov khoom nto yuav tsum tau coated los tiv thaiv khawb.
