Piv nrog rau kev kho phosphating ib txwm muaj, kev kho electroplated silane rau hluav taws xob cua sov raj muaj cov txiaj ntsig zoo hauv qab no:

Nrog rau txoj kev loj hlob ntawm lub zej zog thiab kev txhim kho ntawm industrialization, cov kev cai zoo rau cov khoom kuj nce. Hlau nto kho, raws li ib txoj hauv kev zoo rau kev tiv thaiv cov hlau thiab cov khoom tsis yog hlau, yog siv dav.

Silanized hlau nto kho yog ib puag ncig tus phooj ywg hlau nto tiv thaiv technology uas tau tshwm sim nyob rau hauv xyoo tas los. Piv nrog rau cov txheej txheem phosphating ib txwm muaj, nws muaj cov yam ntxwv ntawm lub zog qis, kev ua haujlwm siab, thiab ib puag ncig tus phooj ywg, thiab tau pib ua haujlwm zoo hauv kev lag luam, maj mam hloov cov tshuaj phosphating tshuab.

Piv nrog rau kev kho mob phosphating ib txwm, kev kho silanization muaj cov txiaj ntsig hauv qab no:

(1) Muab piv nrog cov tshuaj phosphating ib txwm siv, cov txheej txheem silane raws li cov txheej txheem kev kho mob yog yooj yim dua los siv thiab tswj tau yooj yim. Nws tsuas yog yuav tsum tswj hwm tus nqi pH thiab conductivity, tshem tawm qhov yuav tsum tau kho ntau yam xws li cov kua qaub dawb, tag nrho cov kua qaub, txhawb nqa, zinc, npib tsib xee, manganese cov ntsiab lus, thiab kub rau phosphating. Silane kev kho mob tsis muaj kev hloov kho saum npoo av, kev ua kom dhau, thiab cov txheej txheem ntxuav dej, Tsawg cov kauj ruam ntau lawm thiab cov sij hawm kho luv luv pab txhim kho lub Hoobkas muaj peev xwm ntau lawm, txo cov dej khib nyiab, txo cov pa phem ib puag ncig, thiab txo cov nqi tsim khoom.

(2) Nyob rau hauv cov nqe lus ntawm kev siv kub, ib txwm phosphating feem ntau yuav tsum tau kub li ntawm 35 degree mus rau 55 degree los yog siab dua, thaum lub sij hawm silane zaj duab xis txheej txheem yog ib tug tshuaj tiv thaiv nyob rau hauv chav tsev kub. Yog li ntawd, nyob rau hauv kev siv txhua hnub, lub tank tov tsis tas yuav tsum tau rhuab kom ua tiav cov kev kho mob zoo tagnrho. Piv nrog rau phosphating kev kho mob, nws txuag tau ntau lub zog thiab txo cov roj tso pa tawm rau cov ntawv thov kev lag luam;

(3) Cov txheej txheem phosphating yuav tsum tau ntxiv cov nitrite txhawb nqa los tsim nitrite thiab nws cov khoom decomposition, uas ua rau muaj kev hem thawj rau tib neeg kev noj qab haus huv. Tsis muaj nag lossis daus nyob rau hauv cov tshuaj tiv thaiv silylation, yog li tsis muaj sediment tsim nyob rau hauv kev kho mob txhua hnub, tshem tawm cov teeb meem ntawm cov khib nyiab kho nyob rau hauv cov txheej txheem ua ntej kev kho mob thiab zoo txuas mus rau lub tank kua turnover voj voog. Yog tias cov ntxaij lim dej thiab ion exchangers raug teeb tsa, lawv tuaj yeem siv rau hauv lub voj voog kaw.

(4) Nyob rau hauv cov nqe lus ntawm tank ntau npaum, silanization kuj txo los ntawm 20 feem pua ​​​​rau 50 feem pua ​​​​piv rau phosphating, thiab tseem ceeb tshaj, kev noj ntawm silanization ib square meter yog 15 feem pua ​​​​rau 20 feem pua ​​​​ntawm cov tshuaj phosphating. Silanization kuj tseem ua rau lub sijhawm ua haujlwm luv dua piv rau phosphating, yog li txhim kho cov khoom lag luam thiab txo cov khoom siv txuas ntxiv mus.

(5) Ntxiv nrog rau qhov zoo ntawm silane hlau txheej txheej txheej txheem kho, electrodeposition silane hlau nto kho txheej txheem kuj tuaj yeem ua tiav cov txheej txheem tswj tau ntawm silane zaj duab xis los ntawm kev kho cov txheej txheem electrochemical ntawm cov txheej txheem deposition.

(6) Los ntawm kev hloov kho cov khoom siv kho mob phosphating uas twb muaj lawm thiab nqis peev nyiaj me me, phosphating hlau nto kho cov kab ntau lawm tuaj yeem hloov mus rau hauv cov kab ntau lawm rau silanization thiab electrodeposition silanization hlau deg kho.
