Nyob rau hauv lub tshav pob ntawm cov ntawv hlau ua, kev kho deg tsis tsuas yog cuam tshuam cov tsos ntawm cov khoom, tab sis kuj ncaj qha cuam tshuam rau nws cov durability, functionality thiab kev ua lag luam kev sib tw. Txawm hais tias nws yog siv rau cov khoom siv hauv kev lag luam, kev tsim tsheb, lossis cov khoom siv hluav taws xob, cov txheej txheem kho kom zoo tuaj yeem txhim kho cov khoom zoo thiab cov nqi ntxiv. Cov nram qab no 10 cov lus qhia tseem ceeb yog tsim los pab koj txhim kho cov txheej txheem ntws ntawm cov ntawv hlau saum npoo kev kho mob thiab pab ua tiav cov txiaj ntsig zoo dua.
Tswv yim 1: Ua ntej kho
Ua ntej txhua txoj kev kho saum npoo pib, kev kho kom zoo ntawm qhov chaw yog lub hauv paus rau kev ua kom cov nyhuv ntawm kev kho mob tom ntej.
Tshem tawm cov roj saum npoo av, oxides thiab xeb yog thawj txoj haujlwm. Koj tuaj yeem siv cov tshuaj degreasers los yog xeb tshem tawm, ua ke nrog soaking, txau lossis phau ntawv so.
Rau kev tsis sib haum xeeb, kev sib tsoo tshuab (xws li ntawv xuab zeb, sib tsoo log, thiab lwm yam) tuaj yeem siv.
Ua tib zoo saib thaum ua haujlwm:tswj lub zog kom tsis txhob ua kom puas lub substrate nto, tshwj xeeb tshaj yog rau thinner sheet hlau qhov chaw.
Cov lus qhia txog kev txhim kho: Siv cov cuab yeej siv ua ntej ua ntej (xws li cov tshuab tshuaj tsuag) kom ua tau zoo thiab sib xws, tshwj xeeb tshaj yog nyob rau hauv ntau lawm.
Tswv yim 2: Xaiv cov khoom txheej zoo
Cov xwm txheej siv sib txawv muaj cov kev xav tau sib txawv rau cov ntaub ntawv txheej ntawm cov ntawv hlau:
Sab nraum zoov ib puag ncig: Nws raug nquahu kom siv cov txheej txheem nrog cov huab cua tsis zoo, xws li fluorocarbon txheej lossis acrylic txheej.
Cov kev sib txhuam siab: Polyurethane txheej lossis ceramic txheej yog nyiam los ua kom hnav tsis kam.
Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them rau qhov adhesion ntawm txheej, uas tuaj yeem txhim kho los ntawm primer. Rau cov xwm txheej tshwj xeeb xav tau (xws li cov kab mob los yog cov khoom siv insulating), cov txheej txheem ua haujlwm tuaj yeem raug txiav txim siab.
Tswv yim:Ib puag ncig tus phooj ywg thiab qis VOC (volatile organic compound) cov ntsiab lus ntawm cov ntaub ntawv txheej tau dhau los ua kev lag luam, thiab cov xim ntsuab thiab ib puag ncig zoo tuaj yeem nyiam dua.
Tswv yim 3: Optimize spraying process parameters
Txau cov txheej txheem tsis ncaj qha txiav txim siab qhov zoo thiab cov tsos ntawm txheej:
Txau phom deb: Nws yuav tsum khaws cia ntawm 15-25 cm kom tsis txhob sagging los yog coarse hais.
Txau siab: Nws raug pom zoo kom nyob nruab nrab ntawm 0.3-0.6 MPa kom ntseeg tau tias cov xim atomization tsis sib xws.
Txau nrawm thiab lub kaum sab xis: Rau cov khoom ua haujlwm nrog cov duab nyuaj, kho lub kaum sab xis ntawm rab phom txau kom ntseeg tau tias cov txheej txheem sib txawv ntawm cov npoo thiab grooves.
Cov tswv yim txhim kho:Ua cov qauv txheej thwmsim thaum lub sijhawm ua pov thawj cov txheej txheem kom ua kom zoo dua qhov ntsuas qhov ntsuas thiab xyuas kom muaj kev ruaj ntseg hauv kev tsim khoom loj.
Tswv yim 4: Siv electrostatic txau tshuab
Electrostatic txau tau dhau los ua thawj qhov kev xaiv rau niaj hnub kev kho mob saum npoo vim nws qhov siab adhesion thiab uniformity:
Cov nyhuv hauv av yog tus yuam sij rau qhov zoo ntawm cov tshuaj tsuag, thiab cov khoom siv hauv av yuav tsum tau siv los xyuas kom muaj kev ruaj ntseg hluav taws xob.
Kho qhov hluav taws xob electrostatic raws li qhov nyuaj ntawm cov ntawv hlau, feem ntau tswj ntawm 50-80 KV.
Rau cov workpieces complex nrog qhov muag tsis pom los yog kab noj hniav, ib tug dual-phom system los yog phau ntawv pab spraying yuav siv tau kom tsis txhob muaj zog cheeb tsam ntawm lub txheej tshwm sim los ntawm hluav taws xob tiv thaiv tiv thaiv nyhuv.
Tswv yim 5: Phosphating kev kho mob txhim khu kev tiv thaiv corrosion
Kev kho phosphating tuaj yeem tsis tsuas yog txhim kho corrosion kuj ntawm substrate, tab sis kuj txhim kho qhov adhesion ntawm cov txheej tom ntej:
Kev tswj qhov kub thiab txias: qhov pom zoo phosphating kub rau steel yog nyob nruab nrab ntawm 50-70 ℃. Siab dhau los yog qis dhau yuav cuam tshuam qhov sib xws ntawm phosphating zaj duab xis.
Lub sijhawm teem sijhawm: Feem ntau 3-10 feeb, hloov kho raws li cov khoom siv thiab cov txheej txheem.
Txhim kho cov lus pom zoo: Siv cov cuab yeej siv hluav taws xob qis phosphating kom txo tau lub zog siv, thiab ua ke nrog cov tshuaj phosphating ib puag ncig kom txo tau qhov siab ntawm kev kho dej khib nyiab.
Tswv yim 6: Master cov ntsiab lus tseem ceeb ntawm cov txheej txheem electroplating
Electroplating tuaj yeem muab cov khoom zoo nkauj thiab kev tiv thaiv zoo, tab sis nws yuav tsum muaj kev tswj xyuas qhov tseeb ntawm cov txheej txheem:
Qhov ceev tam sim no thiab qhov kub thiab txias yuav tsum nruj me ntsis sib phim. Piv txwv li, thaum galvanizing, qhov kub yuav tsum nyob nruab nrab ntawm 20-30 ℃ thiab qhov ceev tam sim no yuav tsum tau khaws cia ntawm 2-4 A / dm².
Lub concentration ntawm additives nyob rau hauv cov tshuaj electroplating yuav tsum tau saib xyuas tsis tu ncua los xyuas kom meej lub smoothness thiab ceev ntawm txheej.
Lus Cim: Kev ntxuav tom qab electroplating yog qhov tseem ceeb heev. Residual electroplating tov tuaj yeem ua rau cov pos huab lossis corrosion ntawm cov txheej txheej.
Tswv yim 7: Anodizing (tsuas yog rau txhuas qhov chaw)
Anodizing yog cov txheej txheem tseem ceeb los txhim kho corrosion kuj thiab cov nyhuv zoo nkauj ntawm aluminium ntawv hlau qhov chaw:
Qhov hluav taws xob tau pom zoo kom tswj tau ntawm 10-20 V, thiab lub sijhawm ua haujlwm raug kho raws li qhov xav tau (20-60 feeb).
Dyeing thiab sealing tom qab oxidation yog cov kauj ruam tseem ceeb los txhim kho lub peev xwm antioxidant thiab xim durability.
Kev siv thev naus laus zis: Siv micro-arc oxidation (MAO) thev naus laus zis los txhim kho cov tawv tawv thiab hnav tsis kam ntawm oxide zaj duab xis.
Tswv yim 8: nto sib tsoo thiab polishing los txhim kho precision
Kev kho kom zoo saum npoo yog sib cais los ntawm kev sib tsoo thiab polishing:
Sandpaper xaiv: Los ntawm ntxhib mus rau nplua, ib kauj ruam los ntawm kauj ruam, piv txwv li, ua ntej siv 320 #, tom qab ntawd hloov mus rau 800 # lossis siab dua mesh.
Kev ua haujlwm tsis tu ncua: Kev sib tsoo kev taw qhia yuav tsum ua kom zoo ib yam kom tsis txhob hla khawb cuam tshuam rau qhov pom.
Rau workpieces nrog siab gloss yuav tsum tau, daim iav polishing yuav siv tau, ua ke nrog polishing paste los yog chromium oxide paste los txhim kho cov nyhuv.
Tswv yim 9: Txhim khu kev soj ntsuam zoo thiab tswj cov txheej txheem
Kev ruaj ntseg ntawm kev kho deg zoo yog inseparable los ntawm kev tshuaj xyuas thiab tswj:
Txheej thickness gauge: ntes txheej thickness.
Adhesion test: xws li hla-txiav lossis rub-tawm kev sim, txhawm rau xyuas seb cov txheej puas ruaj khov.
Kev kuaj ntsev ntsev: txhawm rau ntsuas kev tiv thaiv corrosion.
Kev txhim kho cov lus qhia: los ntawm kev qhia cov cuab yeej ntsuas kev siv tshuab, ua kom muaj txiaj ntsig ntawm kev sim, thiab sib txuas cov ntaub ntawv txheeb xyuas rau kev ua kom zoo ntawm cov txheej txheem tiag tiag.
Tswv yim 10: Kev kawm tsis tu ncua thiab thev naus laus zis tshiab
Cov cuab yeej kho mob saum npoo yog hloov nrog txhua hnub dhau mus, thiab kom muaj kev coj noj coj ua thev naus laus zis yuav tsum:
Ua tib zoo mloog rau kev lag luam tiam sis: tuav cov txheej txheem tshiab tshaj plaws los ntawm kev koom nrog hauv kev nthuav qhia thiab kev sib tham.
Technology R & D peev: qhia cov cuab yeej ntse thiab cov ntaub ntawv tshiab ib puag ncig los txhim kho kev ua haujlwm thiab kev tiv thaiv ib puag ncig.
Piv txwv li, cov thev naus laus zis tshiab xws li nano coatings thiab plasma spraying yog maj mam nce, muab ntau txoj hauv kev rau kev kho qhov chaw.
