Nyob rau hauv daim teb ntawm sheet hlau ua, kev kho deg nto tsis tsuas yog cuam tshuam rau cov khoom lag luam, tab sis kuj tseem muaj feem cuam tshuam nrog nws cov kev ua haujlwm ruaj khov, kev ua lag luam kev sib tw. Txawm hais tias nws tau thov rau cov khoom siv lag luam, cov khoom siv tsheb tsim khoom, lossis cov txheej txheem hluav taws xob muaj peev xwm txhim kho cov khoom lag luam zoo thiab ntxiv tus nqi. Cov lus qhia tseem ceeb hauv qab no yog tsim los pab koj kom ua kom cov txheej txheem ntws tawm ntawm daim ntawv hlau deg thiab pab kom ua tiav cov txiaj ntsig zoo dua.
Cov Lus Qhia 1: Muaj tseeb ua ntej kev kho mob
Ua ntej cov txheej txheem kev kho mob pib, ua tiav saum npoo av ua ntej yog lub hauv paus rau kom ntseeg tau cov nyhuv ntawm kev kho tom ntej.
Tshem tawm cov roj saum npoo, oxides thiab xeb yog thawj txoj haujlwm. Koj tuaj yeem siv cov kws tshaj lij ntawm cov kws lij choj lossis xeb tshem tawm, sib xyaw ua ke nrog soaking, tshuaj tsuag lossis ntaub so.
Rau cov tawv ncauj sib kis, sib tsoo txhua yam (xws li cov xuab zeb, sib tsoo log, thiab lwm yam) tuaj yeem siv.
Them sai sai thaum ua haujlwm:Tswj lub zog kom tsis txhob ua kom tsis txhob ua kom puas tsuaj rau sab saum npoo av, tshwj xeeb tshaj yog rau thinner daim ntawv hlau.
Cov Lus Qhia Txhim Kho: Siv cov khoom siv hluav taws xob pretreatment (xws li tshuaj tsuag) kom ntseeg tau kev ua haujlwm thiab sib txawv, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb, tshwj xeeb tshaj yog nyob rau hauv ntau lawm.
TSWVW 2: Xaiv cov khoom siv txheej ua kom zoo
Cov xwm txheej hloov sib txawv muaj qhov sib txawv rau cov txheej txheej ntawm cov ntawv hlau:
Kev Pom Sab Nraum: Nws raug nquahu kom siv txheej txheej nrog huab cua siab, xws li cov txheej fluorocarbon lossis acrylic txheej.
Kev sib txhuam siab: polyurethane txheej los yog cov txheej txheem ceramic yog nyiam kom hnav cov hnav tsis kam.
Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them rau cov nplaum ntawm txheej, uas tuaj yeem hloov kho los ntawm Primer. Rau cov xwm txheej tshwj xeeb (xws li cov chaw tiv thaiv kab mob lossis tshuaj pleev cov tshuaj insulual), suav daws teeb meem ua tau zoo.
Cov lus qhia:Cov kev ua phooj ywg ib puag ncig thiab cov khoom sib xyaw qis (volatile organic compound) cov ntsiab lus ntawm cov ntaub ntawv txheej ua lag luam, thiab ntsuab zoo nkauj ua tau zoo dua.
TSWV YIM 3: Ua kom tau zoo ua kom cov txheej txheem txau txau
Txau txheej txheem tsis ncaj qha txiav txim siab qhov zoo thiab pom ntawm cov txheej:
Txau rab phom nrug: nws yuav tsum cia nyob nruab nrab ntawm 15-25 cm kom tsis txhob sagging lossis ntxhib hais.
Txau siab: Nws raug nquahu kom nyob nruab nrab ntawm 0.3-0.6 MPa txhawm rau kom ntseeg tau tias muaj kev sib dhos atomization ntawm cov xim.
Txau nrawm nrawm thiab lub kaum ntse ntse
Kev Txhim Kho Cov Lus Qhia:Coj ua piv txwv cov kev sim ua piv txwv thaum lub sijhawm ua raws cai theem los ua kom pom cov chaw ua kom zoo thiab ua kom ruaj khov hauv cov khoom loj.
Cov Lus Qhia 4: Siv Cov Hluav Taws Xob Hluav Taws Xob
Electrostatic txau tau dhau los ua qhov kev xaiv ua ntej rau kev kho nyob rau hauv niaj hnub vim nws cov adnesion siab thiab cov khaub ncaws hnav zoo:
Cov nyhuv hauv av yog tus yuam sij rau qhov zoo ntawm kev txau ntawm txau, thiab kev lag luam kev lag luam yuav tsum siv los xyuas kom meej lub teb hluav taws xob.
Kho lub tshuab hluav taws xob hluav taws xob raws li kev nyuaj ntawm cov ntawv hlau, feem ntau tswj ntawm 50-80 kV.
Rau cov workpieces nrog lub qhov muag tsis pom kev lossis sab kab hauv qab, ib lub cev phom lossis cov khoom siv phom lim uas siv tau los ntawm cov txheej txheem hluav taws xob los ntawm cov nyhom cov nyhuv hluav taws xob nyhuv.
Tswv yim 5: phosphat kev kho mob txhim kho kev tiv thaiv corrosion corrosion
Phosphating kev kho mob yuav tsis tsuas txhim kho lub corrosion tsis kam ntawm substrate, tab sis kuj txhim kho cov nplaum ntawm cov txheej txheem tom ntej:
Tswj kub: Cov pom zoo phospating kub rau cov hlau yog nruab nrab ntawm 50-70 ℃. Siab dhau los yog qis dhau yuav cuam tshuam kev sib txawv ntawm cov yeeb yaj kiab phosphallity.
Lub sijhawm Teem: feem ntau 3-10 feeb, kho raws cov khoom siv thiab cov txheej txheem uas yuav tsum tau ua.
Kev Tawm Tsam Cov Lus Taw Qhia: Siv cov thev naus laus zis tsawg los txo cov hauv hluav taws xob hauv hluav taws xob, thiab ua ke nrog kev kho kom txo qis ntawm kev siv 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 tiv thaiv kev tiv thaiv, tab sis nws yuav tsum tau ntsuas qhov txheej txheem:
Qhov ntom ntom nti tam sim no thiab ntsuas kub yuav tsum tau ua nruj me ntsis. Piv txwv li, thaum Galvanizing, qhov kub yuav tsum nyob nruab nrab ntawm 20-30 ℃ thiab qhov ceev tam sim no yuav tsum tau tswj hwm ntawm 2-4 A / DM².
Cov concentration ntawm cov kev sib ntxiv hauv cov kev daws teeb meem electroplating yuav tsum raug saib xyuas tsis tu ncua kom ntseeg tau tias cov txheej txheem thiab ntom ntawm txheej.
Nco tseg: Ntxuav tom qab electroplating yog qhov tseem ceeb heev. Residual Electroplating daws teeb meem tuaj yeem ua rau muaj kev ua kom muaj kev mob hlwb lossis xeb nyob rau saum npoo ntawm txheej.
Tswv yim 7: anodizing (tshwj xeeb rau txhuas qhov)
Anodizing yog cov txheej txheem tseem ceeb los txhim kho lub corrosion tsis kam thiab cov txiaj ntsig zoo ntawm txhuas daim ntawv hlau:
Qhov hluav taws xob pom zoo kom raug tswj hwm ntawm 10-20 V, thiab lub sijhawm ua tiav raug muab kho raws li cov kev xav tau (20-60 feeb).
Dowing thiab sealing tom qab oxidation yog cov kauj ruam tseem ceeb los txhim kho kev tiv thaiv kab mob antioxidant thiab xim durabil.
Cov thev naus laus zis: Siv micro-arc oxidation (Mao) thev naus laus zis txuas ntxiv txhim kho lub hardness thiab hnav tsis kam ntawm cov yeeb yaj kiab oxide.
Ntaiv 8: nto sib tsoo thiab polishing los txhim kho qhov tseeb
Kev Kho Mob Zoo Nto yog Inseparable by Sib Tsoo thiab Polishing:
Kev xaiv cov xuab zeb: Los ntawm coarse kom zoo, kauj ruam los ntawm kauj ruam, piv txwv li siv 320 #, tom qab ntawd hloov mus rau 800 # lossis siab dua mesh.
Kev ua haujlwm tshwj xeeb: kev sib tsoo cov kev sib tsoo yuav tsum muaj kev sib tsoo kom tsis txhob hla kev cuam tshuam rau cov tsos.
Rau cov neeg ua haujlwm nrog cov kab lus siab siab, daim iav polishing tuaj yeem siv, ua ke nrog polishing paste lossis chomium oxide muab tshuaj los txhim kho cov nyhuv.
Ntsis 9: Lub Zog Kev Tshawb Xyuas Zoo thiab Kev Tswj Txheej Txheem
Qhov kev ruaj ntseg ntawm kev kho deg zoo yog inseparable los ntawm kev tshuaj xyuas thiab tswj:
Daim txheej tuab ntawm daim ntaub: kuaj cov txheej tuab tuab.
Daim Ntawv Qhia Tawm Lus Qhia: Xws li cov kev txiav txim siab hla los yog rub tawm, txhawm rau paub seb puas muaj cov qauv ruaj khov.
Ntsev tshuaj ntsuas: txhawm rau ntsuas cov corrosion tsis kam.
Kev Txhim Kho Cov Lus Qhia: Los ntawm kev qhia txog cov khoom siv kuaj sim, kom ua tau kev ua haujlwm ntawm kev sim, thiab kev ua kom pom cov ntaub ntawv kev ua haujlwm tiag tiag.
Tswv yim 10: Kev kawm txuas ntxiv thiab thev naus laus zis thev naus laus zis
Kev Kho Mob Hauv Tebchaws yog hloov nrog rau txhua hnub dhau mus, thiab kom muaj cov kev coj ua thev naus laus zis yuav tsum muaj:
Them sai sai rau kev lag luam sib txawv: nkag siab cov txheej txheem tshiab tshaj plaws los ntawm kev koom nrog hauv chaw ua yeeb yam thiab cov lus qhuab qhia.
Technology R & D Kev nqis peev: Qhia cov khoom ntse thiab cov khoom siv zoo ib puag ncig los txhim kho qib thiab ib theem tiv thaiv qib.
Piv txwv li, kev tawm thev naus laus zis xws li cov tshuaj pleev ntshav sov nano thiab cov ntshav txau tau nce qib, muab ntau cov peev txheej rau kev kho cov dej saum npoo av.
