Anti-Corrosion Txheej Nto Kho

Txheej los tiv thaiv corrosion yog hais txog tusyees thov ib txheej ntawm cov xim rau saum npoo ntawm rusty hlau kav kom cais nws los ntawm ntau yam corrosive xov xwm. Nws yog ib txoj hauv kev yooj yim tshaj plaws ntawm cov yeeb nkab steel los tiv thaiv corrosion. Hlau yeeb nkab los tiv thaiv corrosion txheej yog nce siv cov ntaub ntawv sib xyaw lossis cov qauv sib xyaw. Cov ntaub ntawv thiab cov qauv no yuav tsum muaj cov khoom zoo dielectric, lub cev muaj zog, cov khoom siv tshuaj lom neeg ruaj khov thiab dav kub hloov pauv.

Kev kho deg yuav tsum tau ua raws li qhov xav tau, siv txoj kev sandblasting kom tshem tawm xeb. Qhov kev tshem tawm xeb nce mus txog qib Sa2.5... Ua kom tiav tag nrho cov khib nyiab xws li roj, oxide nplai, cov khoom xeb, thiab lwm yam ntawm cov hlau nto. Cov khoom seem xws li duab ntxoov ntxoo kab txaij, me ntsis, thiab lwm yam. pom ntawm qhov muag liab qab yuav tsum tsis pub tshaj 5% ntawm thaj chaw.

Yuav tsum tsis muaj roj thiab av pom ntawm qhov muag liab qab ntawm cov hlau. Txhua qhov seem ntawm nplai, xeb, xim txheej thiab lwm yam txuas yuav tsum yog me ntsis stains nyob rau hauv daim ntawv ntawm cov dots lossis strips.

Tom qab xeb tshem tawm, qhov roughness ntawm lub hauv paus txheej yog tsim kom ncav cuag 40-65 μm, uas yog sib xws nrog cov thickness ntawm cov xim pleev xim rau cov xim primer. Sandblasting: Cov cua compressed siv rau saum npoo yuav tsum muaj lub siab txaus thiab ntws, thiab yuav tsum tsis muaj roj lossis dej. Lub abrasive yuav tsum qhuav, tsis muaj roj, hmoov av thiab lwm yam kab mob.

Qhov chaw ua haujlwm sandblasting tsis raug tso cai nyob ze rau thaj chaw ua haujlwm pleev xim kom tiv thaiv cov xim ntub dej kom tsis txhob muaj plua plav thiab abrasives. Yog hais tias qhov chaw hauv cheeb tsam txwv tsis pub cov xuab zeb blasting thiab painting tsis tuaj yeem sib cais, kev ua haujlwm pleev xim yuav tsum tau ua tom qab kev ua haujlwm sandblasting tiav thiab cov plua plav tau poob.

Ua ntej sandblasting, tag nrho cov welding protrusions, burrs thiab nto protrusions yuav tsum tau polished du, thiab tag nrho cov vuam slag yuav tsum tau ntxuav tam sim ntawd. Tom qab ua tiav qhov pretreatment thiab tshuaj xyuas, painting yuav tsum tau nqa tawm tam sim ntawd kom tsis txhob xeb dua.

Yog hais tias xeb tau tshwm sim ntawm qhov chaw, nws yuav tsum tau sandblasted. Cov khoom uas tsis tuaj yeem sandblasted tuaj yeem raug ntxuav kom ua tiav qib St3.
