Pretreatment thiab electrocoating txheej txheem

Lus piav qhia luv luv:

Txheej txheej pretreatment yog kev npaj ntawm txheej txheej ua ntej txheej thiab yog lub hauv paus ntawm tag nrho cov txheej txheem txheej.
Qhov zoo ntawm pretreatment ncaj qha cuam tshuam rau tag nrho cov txheej zoo, yog li peb yuav tsum xyuam xim rau nws.

Product Description

Ntau yam ntaub ntawv thiab lawv cov khoom nyob rau hauv cov txheej txheem ntawm kev ua, kev thauj mus los, cia, nws nto yog ib qho yooj yim los tsim los yog
lo cov khoom txawv teb chaws, xws li machining burr, oxide daim tawv nqaij, roj, thiab lwm yam., cov kab mob no yuav cuam tshuam rau lub compactness ntawm txheej thiab lub zog sib txuas nrog cov matrix. Txheej pretreatment ntawm lub ntsiab Lub hom phiaj yog tshem tawm cov tshuaj no thiab ua qhov tsim nyog deg tshuaj hloov dua siab tshiab los muab haumCoating yuav tsum tau ntawm lub substrate, thiaj li yuav ua rau kom cov adhesion ntawm zaj duab xis, prolong lub neej kev pab cuam ntawm zaj duab xis, muab tag nrho cov kev ua si rau kev tiv thaiv. effect thiab hniav nyhuv ntawm txheej.

Yog li ntawd, tshuaj tsuag cov ntsiab lus ua ntej ua. Nws feem ntau suav nrog cov hauv qab no:

Degreasing ua ntej txheej

Hlau thiab nws cov khoom nyob rau hauv cov txheej txheem ntawm kev cia thiab kev thauj mus los siv antirust roj tiv thaiv, sheet hlau workpiece nyob rau hauv kos duab roj yuav tsum tau siv thaum lub siab ua, qhov chaw yuav tsum tau hu rau emulsion thaum machining, kev kho cua sov yuav tiv tauj cov roj txias, thaum feem ntau muaj roj. stains thiab HanJi ntawm tus neeg teb xov tooj txhais tes, cov roj ntawm cov khoom tab sis kuj yog cov impurities xws li ib txwm thiab plua plav sib xyaw ua ke Tag nrho cov no, txhua yam roj ntawm qhov chaw tsis tsuas yog cuam tshuam qhov tsim ntawm phosphating zaj duab xis, tab sis kuj cuam tshuam rau adhesion ntawm cov txheej ziab kom qhuav kev ua tau zoo zoo nkauj kev ua tau zoo thiab corrosion kuj Table 3-1 teev qhov sib txawv pretreatment ntawm txias dov steel phaj. Cov nyhuv ntawm cathodic electrophoretic txheej ntawm corrosion kuj.

Phosphating

Phosphating yog ib qho yooj yim, txhim khu kev qha, tsis tshua muaj nqi thiab yooj yim txheej txheem los txhim kho corrosion kuj ntawm hlau nto txheej. Nws tau dav siv nyob rau hauv tsev thiab txawv teb chaws, tshwj xeeb tshaj yog nyob rau hauv lub tsheb txheej, uas yog dav siv nyob rau hauv xyoo tas los no. Yuav luag 100% ntawm cov phaj nyias nyias hauv kev lag luam tsheb yog phosphating phosphating txheej txheem hais txog cov hlau nto hauv kev sib cuag nrog cov kua qaub uas muaj dihydrogen phosphate ntsev, tshuaj lom neeg cov tshuaj tiv thaiv thiab generated nyob rau hauv cov hlau nto stability ntawm insoluble inorganic compound membrane txheej ntawm ib. Txoj kev kho mob saum npoo av thiab cov zaj duab xis generated hu ua phosphating zaj duab xis.

Phosphate zaj duab xis txoj cai

phosphating zaj duab xis muaj peev xwm muab lub hauv paus tsim nyog rau xim txheej, yog vim muaj cov nyhuv hauv qab no:
1) Muab qhov huv si, tsis muaj roj, tsis muaj roj rau ntawm lub hauv paus ntawm kev ua kom tiav degreasing
2) txhim khu cov adhesion ntawm cov organic zaj duab xis rau lub substrate vim lub cev thiab tshuaj ua hauj lwm Nws tsis yog nyuaj rau to taub hais tias lub ntxeem tau ntawm phosphating zaj duab xis ua rau kom lub cheeb tsam ntawm lub substrate, thiaj li hais tias qhov kev twb kev txuas cheeb tsam ntawm ob tsub kom correspondingly, thiab qhov muaj txiaj ntsig zoo permeability ntawm ob txheej zaj duab xis yog generated. Nyob rau tib lub sijhawm, kev sib cuam tshuam tshuaj lom neeg ntawm unsaturated resin thiab phosphate siv lead ua kuj txhim kho nws txoj hlua khi.
3) muab cov txheej txheem kev sib cais ruaj khov, ib zaug cov txheej txheem puas tsuaj, nws muaj lub luag haujlwm ntawm kev tiv thaiv corrosion, tshwj xeeb tshaj yog rau anode incision Thawj taw tes yog feem ntau tsis saib xyuas tsuas yog ua kom tiav rau qhov zoo tshaj plaws ntawm cov roj los tsim cov phosphating zaj duab xis txaus siab. phosphating zaj duab xis nws tus kheej yog cov feem ntau intuitive nyhuv ntawm pretreatment technology ntawm feem ntau txhim khu kev qha ib tug self-kuaj xyuas.
