Cov ntaub ntawv tseem ceeb: Copper strip ntau lawm paub tias cov neeg hlau yuav tsum sau!
Copper sawb yog cov khoom siv hlau ntau heev. Nws yog feem ntau pom nyob rau hauv cov khoom siv hluav taws xob, lub teeb tuav, lub kaus mom roj teeb, cov nyees khawm, ntsaws ruaj ruaj, connectors, thiab lwm yam. Nws lub luag haujlwm tseem ceeb yog ua hluav taws xob, hluav taws xob, hluav taws xob, kev tiv thaiv corrosion, thiab lwm yam. Muaj rau thaj tsam ntawm tooj liab sawb ntau lawm, uas yog thaj tsam ntawm lub cub tawg. , kuaj, txiav cheeb tsam, kub dov cheeb tsam, dej ntxuav thiab phaj dov cheeb tsam. Hnub no tsab xov xwm tsuas yog tham txog cov txheej txheem ntawm cov tooj liab thiab cov kev daws teeb meem rau qee qhov teeb meem, xws li discoloration thiab shear indentation.
Copper strip production process flow:
1. Kev npaj: Raws li lub hom phiaj ntawm kev tsim khoom ua ntej, ntau qhov sib txawv ntawm zinc blocks yog ntxiv rau cov khoom siv tooj liab los tsim cov khoom siv tooj liab ntawm cov khoom sib txawv.
2. Kev soj ntsuam hauv chav kuaj: txhawm rau txhawm rau ua kom tiav cov khoom tiav uas tau txais txiaj ntsig zoo thiab muaj txiaj ntsig zoo, qhov tseeb ntawm cov txiaj ntsig kev kuaj sim yog qhov tseem ceeb heev. Lub luag haujlwm ntawm lub chaw soj nstuam yog kom ceev thiab raug tshaj tawm cov txiaj ntsig kev xeem rau tus tswv ntawm lub cub tawg raws li cov tooj liab thaiv xa mus rau kev tshuaj xyuas.
3. Txiav: Cov tooj liab ua tiav yog rub los ntawm ib txoj hlua dai, muab tso rau hauv lub rooj txiav tshwj xeeb, thiab tom qab ntawd txiav los ntawm lub log txiav. Qhov tsis sib xws ntawm cov tooj liab bar yog ces smoothed los ntawm lub tshuab ntxhua khaub ncaws tooj liab, uas yog qhov zoo rau kev ua haujlwm tom qab. Lub flatness thiab smoothness ntawm tooj liab strip nto.
4. Kub dov: Cov hlais tooj liab yog rhuab ntawm qhov kub ntawm 1000 degree, ces kub dov, thiab dov mus rau hauv ib tug tooj liab strip nrog ib tug tuab ntawm txog 2.3cm.
5. Kev ntxuav dej: Tom qab txhua lub thaiv tooj liab tau dov, vim muaj cov impurities saum npoo, txhawm rau kom tsis txhob cuam tshuam qhov zoo ntawm cov khoom tiav, nws yuav tsum mus dhau ntawm lub qhov cub sealing dua thiab tom qab ntawd mus rau hauv cov txheej txheem ntxuav dej. Qhov chaw ntxuav dej yog muab faib ua ob hom pas dej ua ke raws li acidity. Qhov siab concentration yog 6-8 degrees, thiab qhov qis concentration yog 3-5 degrees.
Ntawm lawv, qhov nruab nrab liab thaj ua rau thaj ntawm tooj liab thiab tooj liab strips tuaj yeem raug ntxuav tawm los ntawm cov kua qaub hauv lub tank ntxhua, thaum cov xim liab tsaus tuaj yeem raug tshem tawm los ntawm txhuam nrog cov plaub hau zoo thaum ntxuav. Cov tooj liab strips tom qab no series ntawm kev kho mob yog obviously lub hauv av ci nrog lub inherent luster ntawm tooj liab. Ib yam li ntawd, yog tias tseem muaj thaj ua rau thaj liab thiab liab thaj ua rau thaj thaum lub sij hawm dov, cov kauj ruam ntxuav dej tseem yuav tsum tau rov ua dua. Thaum lub sij hawm ntxuav, lub acidity nyob rau hauv lub pas dej ua ke yuav tsum tau xyuas tsis tu ncua thiab acid yuav tsum tau ntxiv nyob rau hauv lub sij hawm kom tsis txhob muaj txaus ntxuav vim tsis muaj acid cov ntsiab lus.
6. Phaj dov: Lub phaj dov cheeb tsam yog muab faib ua 180 ua ntej dov thiab 110 nruab nrab dov raws li qhov chaw ntawm cov menyuam. Raws li qhov sib txawv ntawm ntau qhov sib txawv, cov kub dov tooj liab strips uas tau forged nyob rau hauv lub qhov cub sealing yog ua tiav los ntawm ntxhib mus rau nplua los ntawm ob kauj ruam saum toj no.
Kev daws rau cov teeb meem tshwm sim nrog tooj liab strips:
1. Tshuaj rau discoloration ntawm tooj liab strips
(1) Tswj cov concentration ntawm acid thaum pickling. Nyob rau hauv cov ntaub ntawv ntawm ntxuav tawm cov oxide txheej ntawm qhov chaw ntawm lub annealed tooj liab sawb, ib tug siab acid concentration tsis muaj kev nkag siab. Ntawm qhov tsis sib xws, yog tias cov concentration siab dhau lawm, cov kua qaub seem uas txuas rau saum npoo ntawm cov tooj liab tsis yooj yim los ntxuav, thiab nws ua kom cov pa phem ntawm cov dej ntxuav, ua rau cov concentration ntawm cov kua qaub nyob hauv cov dej ntxuav. siab dhau heev lawm, ua rau cov kab hlau ntxuav tau zoo dua tuaj yeem hloov xim. Yog li ntawd, thaum txiav txim siab qhov concentration ntawm cov tshuaj pickling, yuav tsum tau ua raws li cov hauv qab no: nyob rau hauv lub hauv paus ntsiab lus hais tias cov oxide txheej nyob rau saum npoo ntawm tooj liab sawb yuav tsum tau ntxuav, lub concentration yuav tsum tau txo kom ntau li ntau tau.
(2) Tswj cov conductivity ntawm cov dej ntshiab. Tswj cov dej ntshiab, uas yog, tswj cov ntsiab lus ntawm cov khoom tsis zoo xws li chloride ions hauv dej ntshiab. Feem ntau, nws muaj kev ruaj ntseg los tswj cov conductivity qis dua 50μS / cm.
(3) Tswj cov conductivity ntawm cov dej kub ntxuav thiab passivation tus neeg sawv cev. Qhov nce hauv conductivity ntawm dej kub ntxuav thiab passivation tus neeg sawv cev tsuas yog los ntawm cov residual acid coj los ntawm khiav tooj liab sawb. Yog li ntawd, thaum ua kom ntseeg tau qhov zoo ntawm cov dej ntshiab rau kev ntxuav, tswj cov conductivity txhais tau tias tswj cov kua qaub seem. Raws li ntau qhov kev sim, nws muaj kev nyab xeeb los tswj cov dej kub ntxuav thiab tus neeg sawv cev passivation hauv qab 200 μS / cm feem.
(4) Xyuas kom cov sawb tooj liab qhuav. Ib feem muab lub qhov hluav taws xob coiling ntawm lub tshuab cua cushion rauv, thiab siv lub tshuab dehumidifier thiab cua txias hauv ib feem ntawm cov khoom siv los tswj cov av noo thiab qhov kub thiab txias thaum lub sij hawm tooj liab coiling nyob rau hauv ib qho chaw.
(5) Siv tus neeg sawv cev passivation kom passivate. Feem ntau cov nroj tsuag ua tooj liab tam sim no siv benzotriazole, los yog BTA (molecular mis: C6H5N3) ua tus neeg sawv cev passivating. Kev xyaum tau ua pov thawj tias nws yog ib qho yooj yim rau kev siv, kev lag luam thiab siv tau tus neeg sawv cev passivation. Thaum cov tooj liab hla dhau los ntawm BTA cov tshuaj, cov oxide zaj duab xis ntawm qhov chaw tau dhau los ua cov tshuaj tiv thaiv complexing nrog BTA los ua ib qho nyuaj, uas tiv thaiv cov tooj liab matrix.
2. Kev daws rau tooj liab strip shear indentation
Txhawm rau tiv thaiv shear blade indentation, nws yog ib qho tsim nyog yuav tau xaiv ib rab riam uas tsim nyog thiab qhov sib txawv ntawm txoj kab uas hla ntawm cov roj hmab stripping nplhaib raws li thickness, softness thiab hardness ntawm cov sawb; lub hardness ntawm cov roj hmab stripping nplhaib ua tau raws li qhov yuav tsum tau siv ntawm kev txiav sawb; thaum txiav Thaum qhov dav ntawm lub sawb me me, lub thickness ntawm cov riam ncig yuav tsum raug xaiv kom tsim nyog los ua kom qhov dav ntawm cov roj hmab tev nplhaib.
