Yuav ua li cas kom tsis txhob xeb tom qab vuam?

Vuam tsim cov pob qij txha muaj zog, tab sis cov cua sov siab tuaj yeem ua rau cov khoom siv tiv thaiv kev puas tsuaj ntawm cov hlau, tawm ntawm thaj chaw weld thiab ib puag ncig thaj chaw tsis muaj xeb. Cov tshuaj xeb thaum cov hlau nyob hauv cov hlau reacts nrog oxygen thiab noo noo, thiab welded thaj chaw tshem tawm cov xim sib tw, lossis cov roj oxide, ua rau cov hlau oxide. Nres kev xeb tom qab vuam yuav tsum muaj txoj hauv kev kom huv si los ntxuav, kho, thiab tiv thaiv cov weld thiab nws ib puag ncig.
Kauj ruam 1: Ntxuav cov chaw weld kom huv si
Kev tiv thaiv xeb pib nrog kev tshem tawm cov paug tsis huv thiab ua kom muaj kev xeb. Txawm tias tus nqi me me ntawm cov nplais me, nti, lossis roj tuaj yeem dhau los ua cov xeb xeb:
• Tshem cov slag thiab spritt: siv cov xaim txhuam, lossis graint nrog lub log xaim (los ntawm kev siv hlau kom huv si) Slraps noo noo tiv thaiv cov nplaim, thaum lub ntsej muag ua cov khoom uas tsis sib xws nyob qhov twg xeb tuaj yeem tuav tau. Rau cov hlau tsis zoo li stainless hlau, siv ib qho tsis- abon txhuam kom tsis txhob khawb qhov chaw (khawb kuj tuaj yeem ua rau xeb).
• Tshem cov roj thiab cov roj: vuam ntau dua cov roj cov roj residue los ntawm cov pub hnab looj tes, hnab looj tes, lossis tshuaj ntxuav. So thaj chaw nrog kev haus dej cawv (acetone, lossis cov roj hlau tshem tawm)} Cov roj pleev cov roj pleev thiab ntxiab ya raws. Ua raws li nrog daim ntaub huv thiab qhuav kom ua kom muaj cov seem seem.
• Grind thaiv: Siv grinder nrog tus nrov plig plawg disc kom du peld hlaws dai, lossis thaj chaw tsis ncaj, lossis thaj chaw tsis ncaj. Cov xwm txheej no sau cov av thiab noo noo, ua cov xeb ntau dua. Tsom rau txoj kev du, hnav ua tiav uas tso cai tiv thaiv kev tiv thaiv kom ua raws li tusyees.
Kauj ruam 2: Kho cov hlau uas raug cov hlau tam sim ntawd
Tom qab tu, cov hlau liab (tshwj xeeb yog cov weld nws tus kheej) yog qhov yooj yim rau xeb kom xeb rau cov av noo tuaj yeem pib cov txheej txheem. Kho thaj chaw nrog ib xeb -}}}} inhibiting daws los yuav lub sijhawm tiv thaiv kev tiv thaiv zaum kawg:
• Thov ib qho kev hloov pauv xeb: rau cov hlau me, siv cov xeb sib hloov (tshuaj siv tshuaj txhuam (cov tshuaj lom neeg muaj cov tannic acid lossis phosphoric acid). Nws reacts nrog ib tug muaj xeb uas twb muaj lawm los ua ib txheej ruaj khov, inert txheej uas txwv tsis pub corrosion ntxiv. Txhuam nws rau hauv weld thiab nyob ib puag ncig 2-3 nti ntawm cov hlau, cia kom qhuav (feem ntau yog 2-4 teev), thiab so tawm ntau dhau. Qhov no ua haujlwm zoo rau Welds uas yuav pleev xim rau tom qab.
• Siv zinc - Nple Mish Primer: Zinc {1} {}}}}} dinlying steel. Lawv yog qhov zoo tagnrho rau cov txheej txheem welds ntawm cov hlau me me, xws li cov txheej txheem tsheb lossis cov nkhaus hlau. Thov ib qho nyias nyias, txawm lub tsho tiv no nrog cov txhuam hniav lossis tshuaj tsuag, thiab cia nws ua kom tiav (check cov lus qhia rau lub sijhawm kom qhuav) ua ntej ntxiv cov todcoats.
• Ua kom dhau stainless hlau: Stainless hlau relies ntawm lub chromium oxide txheej nyob ze ntawm weld, tsim "cov chaw siab mus rau xeb. Dhau cov weld los ntawm kev thov nitric acid lossis citric acid daws teeb meem (kev lag luam passivators muaj rau kev nyab xeeb). Qhov no restores lub chromium oxide txheej-} Soak thaj tsam rau 20-30 feeb, yaug nrog dej, thiab ua kom qhuav.
Kauj ruam 3: Thov kev tiv thaiv kev tiv thaiv
Thaum cov weld huv si thiab kho kom huv, ib qho kev tiv thaiv kev tiv thaiv ruaj khov tawm noo noo thiab oxygen - ob cov khoom xyaw xav tau rau xeb. Xaiv cov txheej txheej raws li cov hlau thiab ib puag ncig:
• Rau cov hlau me me:
★Taint: Siv qhov siab - Cov txha txha txha, epoxy, lossis polyurethane pleev xim. Epoxy cov xim muaj xim yog qhov zoo tshaj rau sab hauv lossis sab nraum zoov (piv txwv li, thaum muaj rooj tog zaum sab nraum zoov), thaum Polyurethane muaj cov khoom zoo ib yam li fences lossis txhais tes. Thov kom siv 2-3 lub tsho ntev, tso cai rau txhua qhov kom qhuav tag nrho, thiab nthuav cov xim 1-2 nti dhau ntawm Weld kom them cov hlau.
◦Powder txheej: ib qho kev xaiv ruaj khov rau cov hlau seem uas tuaj yeem tiv taus siab dua siab (txog 400℃f). Hmoov txheej melts thiab tsim ib txheej nyuaj, txheej sib txig uas muab khi ntsaws ruaj ruaj rau Weld kiag li. Nws yog qhov zoo tagnrho rau cov khoom lag luam, tshuab, lossis hlau kos duab, raws li nws tawm tsam chipping thiab fading.
Ooloil lossis wax: rau kev tiv thaiv ib ntus (piv txwv li, seem hauv cia), thov ib lub tsho tiv no rau hauv lub tshuab roj, beeswax, lossis ib xeb-}}}}} Kev tiv thaiv txau. Qhov no cov roj hmab noo tab sis xav tau kev thov rov ua txhua ob peb lub hlis.
• Rau cov hlau tsis muaj hlau hlau:
◦inCe lub tsho tiv no: cov txheej txheem ntshiab lossis epoxy khaws cia cov hlau stainless lub ntsej muag thaum ntxiv ib qho kev nyab xeeb noo. Qhov no yog qhov muaj txiaj ntsig rau cov ntaub ntawv pom ntawm cov khoom siv, xuas tes ua, lossis cov hlau zoo nkauj.
◦no txheej (yog tias passivated): Txawm li cas los xij, hauv cov ntug hiav txwv lossis siab {{2} noo noo noo noo ntxiv tiv thaiv cov tshuaj tsuag ntsev ntxiv.
• Rau Txhuas Welds:
◦odizing: anodizing tsim cov tuab, porous oxide txheej ntawm txhuas uas tuaj yeem ua kom tau los yog kaw. Nws yog qhov zoo tagnrho rau txhuas welds nyob rau hauv cov rooj tog hauv sab nraum zoov, chaw marine, lossis nws tiv taus corrosion thiab hnav.
Usaluminum Primer + Xim: Rau cov phiaj xwm txhuas ua kom tiav rau txhuas (txhawm rau kom pom tseeb) ua raws li cov tshuaj ntsuab lossis cov tolamel topcoat. Qhov no ua haujlwm zoo rau txhuas thav ntawv lossis DIY hlau tej yaam num.
Kauj ruam 4: Saib xyuas qhov ntev ntev - sij hawm
Txawm hais tias nrog kev tiv thaiv kom tsim nyog, xeb tuaj yeem txhim kho lub sijhawm yog tias cov pleev xim puas lawm. Kev tu ib txwm khaws cia xeb ntawm bay:
• Soj ntsuam tsis tu ncua: tshuaj xyuas Welds txhua 3-6 lub hlis (ntau zaus hauv thaj chaw noo lossis dej hiav txwv) rau cov cim ntawm chipping, tawg, lossis xeb, lossis xeb, lossis xeb, lossis xeb, lossis xeb, lossis xeb, lossis xeb, lossis xeb, lossis xeb, lossis xeb, lossis xeb, lossis xeb, lossis xeb, los yog xeb. Txais cov teeb meem me me tiv thaiv lawv los ntawm kis mus.
• Kov cov chaw uas puas lawm: Yog Xim lossis pleev xim rau, ntxuav qhov chaw uas muaj xeb (yog tias xeb rov qab), thiab kov nrog cov xim sib piv lossis cov khoom siv.
• Ntxuav Welfaces huv si: Rau Weldsrace sab nraum zoov, yaug nrog dej tsis tseg kom tshem tawm ntsev, av, lossis cov khib nyiab uas tuaj yeem nkag ya raws. Zam kev nyab xeeb tshuaj, uas tuaj yeem ua kev puas tsuaj.
• Tswj ib qho kev tswj hwm: Khaws welded cov khoom hauv qhuav, zoo - pa taws thaj chaw. Txog cov cuab yeej lossis cov hlau seem, siv noo noo -} nqus desiccant pob hauv cov thawv ntim khoom.
Kev txiav txim siab tshwj xeeb rau high- txoj kev pheej hmoo
Welds nyob rau hauv cov chaw hnyav (ntug dej hiav txwv, kev lag luam, lossis hauv qab) Xav tau kev tiv thaiv ntxiv:
• Galvanizing: kub {{- dip galvanizing (rub lub zinc tuab hauv Molten Zinc Txheej uas tiv taus Saltwater thiab tshuaj lom neeg. Nws yog qhov zoo tagnrho rau sab nraum zoov qauv hlau, xws li Choj Cheebtsam lossis cov khoom siv marine.
• Cathodic Kev Tiv Thaiv: Rau cov chaw muag khoom tso zis (piv txwv li, cov raj xa dej hauv qab (zinc lossis cov hlau nplaum) txuas nrog cov hlau. Lub anode corrodes hloov weld, tiv thaiv xeb.
• Tsoom cij: Thov cov khoom siv silicone lossis polyurethane nyob ib ncig ntawm welds nyob rau thaj chaw ntub dej (piv txwv li cov kav dej sib xyaw ua ke lossis sab nraud thaiv cov dej intrusion. Xaiv cov neeg sib foob ntawm ib puag ncig (piv txwv li, marine - qib rau sillwater).
Xaus: Kev tiv thaiv pib nrog kev npaj
Nres kev xeb tom qab vuam yuav tsum muaj kev ua ke tu, kho, thiab tiv thaiv thaj chaw weld. Los ntawm kev tshem tawm cov paug, kho cov txheej txheem tiv thaiv, thiab siv cov dej noo thiab cov pa- tshem tawm cov kev mob rau xeb. Kev tu ncua ib txwm ua kom ntev - tsis muaj kev tiv thaiv, txawm tias nyob rau ib puag ncig hnyav.
Nco ntsoov: tus ua ntej koj nyob ntawm Weld tom qab txias, zoo dua. Kev ncua kev ntxuav thiab kev tiv thaiv muab cov xeb dej xeb, ua rau nws nyuaj rau tom qab. Nrog cov kauj ruam no, welded pob qij txha tuaj yeem muaj zog thiab xeb {{2} Pub dawb rau xyoo.
