Cov ntsia hlau nruab nrab ntawm tus pas nrig dai thiab cov kab hluav taws xob yuav tsum tau nruj me ntsis.Ua ntej khi cov khoom, peb yuav tsum xub xyuas seb lub hanging pas nrig yog tsau xoob.Yog hais tias nws yog me ntsis xoob, nws yuav tsum tau nruj me ntsis nyob rau hauv lub sij hawm.Lwm corrosion, dai pas nrig yuav ua me me, yuav tsum tau hloov nyob rau hauv lub sij hawm, vim hais tias nws conductive cheeb tsam yog me me, yooj yim los ua cua sov, tib lub sij hawm los khi, tiv thaiv cov profile poob rau hauv lub qhov uas tshwm sim los ntawm tus ncej, luv luv Circuit Court puas rau lub hwj chim mov.
Nyob rau tib lub sij hawm poob rau hauv lub profile ntawm lub tank yuav tsum tau muab ntxuav tawm nyob rau hauv lub sij hawm, xws li alkali ntxuav tank rau hauv ib tug profile, nws yuav sai sai corrosion, qhov kev sim ua pov thawj tias alkali noj yog sib npaug rau alkali ntxuav ntawm 50-100. hauv paus ntawm cov profile ntawm cov alkali noj.Poob rau hauv cov xim tank los yog sealing tank, vim corrosion, lub tank yuav sau ib tug loj tus naj npawb ntawm txhuas ions, cuam tshuam rau lub neej kev pab cuam ntawm lub tank kua.
Kev khi cov khoom siv nrog txhuas hlau nrog ob hom kev qhia tshwj xeeb yog qhov zoo, aniseed xaiv coarse txhuas hlau, cov khoom nruab nrab thiab cov khoom me me yog siv rau hauv cov hlau zoo txhuas, siv tau 2 hli thiab 3 hli, los yog 2.2 hli thiab 3.2 hli ob hom specifications, txhuas hlau annealing hardness yuav siv sij hawm 1/2 ~ 3/4 yog zoo.Tam sim no, ntau lub lag luam tau hloov dua siab tshiab rau jig.
Ua ntej dai rau hauv lub tank oxidation kom nruj txhua qhov profile; Cov khoom siv rov ua dua ua ntej oxidation ntawm cov khoom siv, siv cov pliers los tuav qhov kawg ntawm qhov profile kom nws hloov ua ntej cov khoom, kom cov kev sib cuag tsis muaj zaj duab xis, kom ntseeg tau zoo conductivity .
Cov khoom siv dai rau hauv lub tank oxidation thiab xim tank conductive lub rooj yuav tsum tau them sai sai rau txoj cai, txwv tsis pub nws yog qhov sib txawv ntawm Yin thiab Yang complexion.
Tom qab qhov kawg ntawm lub zog oxidation raug tshem tawm hauv lub sijhawm, nyob hauv lub tank oxidation rau ob peb feeb yuav cuam tshuam rau lub qhov sib khi, tseem yuav ua rau cov xim nrawm nrawm; Tom qab oxidation, nws yog lifted thiab qaij nyob rau hauv cov huab cua ntev dhau lawm.Ib qho kawg ntawm cov kua qaub txo cov kua qaub yog darkened vim qhov pore expansion ntawm oxide zaj duab xis, thiab xim txawv ntawm ob qho tag nrho yog ib qho yooj yim mus tshwm.
Tus nqi pH ntawm plaub lub taub dej ntxhua ua ntej thiab tom qab lub tank xim yuav tsum tau khaws cia kom ruaj khov.Tus nqi pH ntawm plaub lub taub dej ntxhua khaub ncaws yog tswj raws li hauv qab no:
Tus nqi pH ntawm thawj da dej tom qab oxidation: 0.8 ~ 1.5
Tus nqi pH ntawm lub da dej thib ob tom qab oxidation: 2.5 ~ 3.5
Tus nqi pH ntawm thawj da dej tom qab xim: 1.5 ~ 2.5
Tus nqi pH ntawm lub tank thib ob tom qab xim: 3.5 ~ 5.0
Raws li qhov xwm txheej ib txwm muaj, qee qhov dej ntws tawm tau qhib thaum lub sijhawm tsim khoom, thiab lub valve nkag tau raug kaw thaum lub sijhawm tsim khoom.Nws yuav tsum tsis txhob ntws los yog ntxiv dej rau hauv tag nrho lub tank.Yog tias cov dej nyob twj ywm hauv thawj lub tank tom qab oxidation rau ob peb feeb, cov xim yuav nrawm dua, thiab yog tias cov dej nyob twj ywm hauv lub tank thib ob, cov xim yuav qeeb.
Rau kev tsim cov khoom siv xim xim imitation steel, txoj kev xim feem ntau tau txais ua ntej, tom qab ntawd rov qab mus rau cov qauv xim phaj.Vim cov xim sib txawv ntawm cov xim hlau xim lub sij hawm tswj ntau yam me me (tsuas yog 2 ~ 3 vib nas this) , thiab siv txoj cai fading tuaj yeem muaj 10 ~ 15 vib nas this ntawm lub sijhawm tswj xim, thiab kev sib koom ua ke fading kuj yog qhov tsim nyog rau tib xim tom qab, rau cov imitation steel fading thiab cov xim ntxiv yog xim zoo li tig ntsuab, thiab xim ib zaug yuav nyiam. ua liab.
Hom khoom dai ntawm lub tank xim thiab thawj lub tank ntxuav tom qab xim tom qab dai tsis txhob tso tseg lub sij hawm khoob yog ntev dhau lawm, txwv tsis pub cov profile nto yuav tshwm ribbon, xim tsis sib xws thiab cov kua dej kawg ntawm qhov tshwm sim dawb, yuav tsum yog me ntsis ntawm cov xim ntawm Tom ntej no ntxuav nyob rau hauv lub sij hawm, qhov tseeb xim yuav tsum yog nyob rau hauv lub thib ob ntxuav tom qab. Feem ntau hais lus, rau imitation steel cov ntaub ntawv, xws li sib piv template xim liab, nws qhia tau hais tias lub sij hawm colouring tsis txaus rau ntxiv cov xim; Yog hais tias cov xim yog daj. , nws tau ua xim, raws li xim qhov tob, koj tuaj yeem xaiv rov qab rau hauv lub tank xim lossis hauv thawj lub tank ntxhua tom qab xim.
Ntxiv txoj kev ntawm cov tshuaj nyob rau hauv lub colouring tank: stannous sulfate thiab npib tsib xee sulfate yuav tsum tau yaj nyob rau hauv lub tank, thiab cov xim additive yuav tsum tau yaj nyob rau hauv cov dej ntshiab (cov dej ntshiab yog soluble).Nws yuav tsum raug sau tseg tias cov khoom siv ntxiv tuaj yeem nchuav tom qab yaj tag, thiab cov concentrated sulfuric acid tuaj yeem raug nchuav ncaj qha rau hauv lub tank xim.
Qhov kub, sijhawm thiab dej zoo ntawm cov dej kub ntxuav ua ntej electrophoresis yuav tsum tau lav.Yog tias qhov seem SO42- nyob rau hauv lub qhov oxide zaj duab xis tsis tau ntxuav, yellowing thiab opacity ntawm cov xim zaj duab xis yuav tshwm sim tom qab electrophoresis thiab ci.Raws li cov xwm txheej, cov dej kub kub tswj ntawm 60 ~ 70 ℃, thiab cov dej kub ntxuav. lub sijhawm yog 5 ~ 10 feeb.
