Tiv thaiv lub cev ntawm lawv lub tsheb los ntawm kev xeb, cov tswv tsheb siv ntau txoj hauv kev. Qee tus tuav lub tsheb hauv chaw nres tsheb thiab tsis txhob tawm hauv lub caij ntuj no, lwm tus ntxuav nws txhua lub lim tiam, thiab lwm tus kho nws nrog cov khoom siv tiv thaiv corrosion. Hmoov tsis zoo, niaj hnub no tsis muaj ib qho kev daws teeb meem rau kev tiv thaiv corrosion, tab sis muaj ib txoj hauv kev uas tuaj yeem tiv taus cov txheej txheem ntawm cov hlau oxidation - galvanizing lub tsheb lub cev.

Cov tshuab no nyob deb ntawm qhov tshiab thiab tau siv los ntawm qee tus neeg tsim khoom siv sijhawm ntev. Nws muaj txiaj ntsig zoo dua li txhua txoj hauv kev ntawm kev tswj xeb thiab muaj peev xwm tiv taus nws tau ntau xyoo. Peb yuav tham txog dab tsi galvanized tsheb lub cev yog nyob rau hauv tsab xov xwm no. Peb yuav saib cov txheej txheem uas twb muaj lawm rau kev siv cov txheej txheem tiv thaiv hauv cov chaw tsim khoom thiab hauv tsev.

Dab tsi yog galvanization

Galvanizing lub cev lub cev yog txheej txheem ntawm txheej txheej ntawm zinc. Cov hlau no xyaum ua haujlwm tiv thaiv corrosion thiab tiv thaiv cov txheej txheem tsis yog los ntawm ya raws, tab sis kuj los ntawm lwm yam tshuaj lom neeg. Automakers siv galvanizing rautshuab dhos theem. Nws yuav ua tiav lossis ib nrab. Hauv thawj kis, tag nrho cov ntsiab lus ntawm lub cev tuaj yeem ua tiav, ob qho tib si los ntawm sab nraud thiab sab hauv. Qhov kev xaiv thib ob yog txheej txheej nrog zinc tsuas yog cov khoom uas feem ntau raug kev txom nyem los ntawm kev cuam tshuam nrog ib puag ncig nruj: hauv qab, sills, fenders, thiab lwm yam.

Txoj kev ntawm galvanizing

Tsuas muaj peb txoj hauv kev los thov txheej zinc rau lub cev hlau:

• electroplated;
• thermal;
• txias.

Cia saib txhua tus kom meej ntxiv.

Galvanic method

Galvanic galvanizing ntawm lub tsheb lub cev txhais tau tias tso nws (los yog nws tus kheej lub ntsiab) nyob rau hauv ib lub thawv nrog ib tug tej yam electrolyte. Lub thawv lub cev txuas nrog qhov zoo electrode ntawm lub zog hluav taws xob, thiab cov khoom yuav tsum tau ua tiav yog txuas nrog qhov tsis zoo. Yog tsis nkag mus tob rau hauv cov txheej txheem electrochemical, thev naus laus zis tuaj yeem piav qhia yooj yim raws li hauv qab no. Zinc hais nyob rau hauv cov electrolyte yog ceev nyob rau hauv lub zog ntawm hluav taws xob thiab pib txav ntawm lub anode mus rau cathode, i.e. rau lub cev, thiab npog nws nrog ib txheej nyias tab sis txuas ntxiv. Galvanized galvanizing thev naus laus zis raug suav hais tias yog txoj hauv kev zoo tshaj plaws los tiv thaiv corrosion, txij li ib feem yog npog nrog txheej tiv thaiv ntawm txhua sab.

Thermal (thermal diffusion) txoj kev ntawm galvanizing

Cov txheej txheem thermal muaj nyob rau hauv qhov chaw yuav tsum tau ua hauv da dej nrog kub zinc tov, qhov twg, nyob rau hauv lub cawv.kub, kev tiv thaiv yog thov nyob rau hauv ib tug nyias txheej rau cov hlau. Qee lub tuam txhab tsheb xyaum siv zinc rau cov ntawv hlau los ntawm lub cev ua, txawm tias nyob rau hauv cov txheej txheem ntawm dov nws. Txoj kev no yog me ntsis qis hauv kev ua haujlwm zoo rau galvanic, tab sis kuj tseem ua haujlwm zoo tiv thaiv xeb. Cov neeg Asmeskas yog thawj tus tsim tsheb nrog kub-dip galvanized lub cev, tab sis tom qab ob peb xyoos, thev naus laus zis kis mus rau Tebchaws Europe.

Cold application method

Txoj kev no yog ze rau galvanic, tab sis nws tsis tas yuav muaj peev xwm. Ntawm no txhua yam tshwm sim nrog kev pab los ntawm ib tug tshwj xeeb electrode, active muaj pes tsawg leeg ntawm zinc. Nws txuas nrog lub davhlau ya nyob twg zoo ntawm lub zog hluav taws xob, thiab cov khoom yuav tsum tau ua tiav yog txuas nrog qhov tsis zoo. Thaum cov electrode cuam tshuam nrog ib feem, zinc particles nyob rau hauv lub zog ntawm hluav taws xob kis los ntawm cathode mus rau lub anode, npog nws nrog ib tug tiv thaiv txheej. Txias galvanizing ntawm lub tsheb lub cev feem ntau yog siv los ua nws tus kheej cov ntsiab lus thiab tsis tshua muaj siv los ntawm automakers.

Yuav ua li cas thiaj paub yog tias koj lub tsheb yog galvanized

Vim tias tsis yog txhua lub tuam txhab tsheb siv cov cuab yeej tiv thaiv uas tau teev tseg, nws yuav tsis tawm ntawm qhov chaw kom paub seb koj lub tsheb puas tau raug kho zoo li no, thiab seb koj puas tuaj yeem cia siab tias nws cov hlau tuaj yeem tiv taus corrosion. Tab sis yuav ua li cas txiav txim siab galvanization ntawm lub cev tsheb yog tias nws pleev xim?

Txoj kev yooj yim tshaj plaws thiab paub tseeb tshaj plaws yog nyeem phau ntawv tus neeg siv. Yog lub cev dhau musxws li kev ua, koj yuav twv yuav raug hu pom cov cim coj hauv daim ntawv. Txoj kev thib ob yog kuaj lub tsheb los ntawm VIN code. Cov lus teb tau txais yuav muaj cov ntaub ntawv hais txog seb lub cev puas yog galvanized.

Zoo, txoj hauv kev kawg yog kev kuaj pom ntawm lub tshuab. Yog tias lub cev muaj kev puas tsuaj rau cov xim pleev xim, thiab hauv qab lawv koj yuav pom cov yam ntxwv grey txheej, koj tuaj yeem paub tseeb tias lub tsheb yog galvanized. Koj tuaj yeem tshawb xyuas hauv qab, fragmentarily tshem tawm cov av thiab ib txheej ntawm kev tiv thaiv corrosion los ntawm nws. Nws yuav tsis yog superfluous mus saib hauv pem teb ntawm lub cabin, tom qab thawb lub ntaub pua plag.

Puas yog ua tau galvanize hauv tsev thiab dab tsi yuav tsum tau rau qhov no

Ua-nws-koj tus kheej galvanizing ntawm lub tsheb lub cev yog qhov ua tau, tab sis nws tsis txhais tau tias tag nrho, tab sis ib feem ntawm cov ntsiab lus nrog cov txheej txheem tiv thaiv. Cov no tuaj yeem yog thaj chaw uas muaj feem cuam tshuam rau corrosion: fender liner, sills, thaj chaw hauv qab taw ntawm tus neeg tsav tsheb thiab cov neeg caij tsheb, daim npav qhov rooj, nrog rau qhov chaw uas cov xim pleev xim puas lawm.

Txoj hauv tsev ntawm kev siv zinc tiv thaiv yog qhov sib txawv ntawm qhov txias galvanizing thiab galvanizing. Tab sis ntau ntxiv txog qhov ntawd tom qab. Thiab tam sim no txog dab tsi yuav tsum tau rau qhov no.

Yuav tsum muaj cov cuab yeej thiab cov cuab yeej:

• hnab looj tes roj hmab;
• zinc chloride lossis sulfate (soldering acid);
• khoom zinc;
• iav tais;
• tsheb roj teeb lossis charger;
• ib daim ntaub huv si (gauze);
• sandpaper;
• degreaser (solvent);
• baking soda tov.

Yog tias koj tsis tuaj yeem yuav cov tshuaj npaj ua tiav ntawm zinc ntsev, nwskoj tuaj yeem ua noj ntawm koj tus kheej. Ua li no, noj sulfuric lossis perchloric acid thiab yaj cov zinc hauv nws hauv qhov sib piv ntawm 1: 0, 4, i.e. rau ib liter ntawm acid - 400 g. hlau.

Qhov no ua tiav raws li hauv qab no. Ncuav cov kua qaub rau hauv khob tais (iav, hub) thiab muab zinc rau hauv cov koob kom txog thaum lawv tsis sib cuam tshuam. Cov tshuaj tiv thaiv tshwm sim nyob rau hauv daim ntawv ntawm dissolution ntawm cov hlau nrog kev tso tawm ntawm hydrogen. Yog li ntawd, yuav tsum ceev faj heev: ua haujlwm nrog cov hnab looj tes thiab kom deb ntawm qhov chaw qhib cua sov. Thaum cov tshuaj tiv thaiv nres, cov tshuaj tuaj yeem txiav txim siab npaj txhij. Lim nws thiab ntws cov sediment. Tam sim no koj tuaj yeem mus rau qhov txheej txheem tam sim ntawd.

Peb zinc lub cev nyob hauv tsev

Galvanization ntawm lub cev lub tsheb tsuas yog tuaj yeem nqa tawm hauv thaj chaw yav dhau los ntxuav ntawm cov xim, av, plua plav, xeb, txheej txheem dej. Ua li no, thaj chaw yuav tsum tau kho yog ntxuav nrog ntawv xuab zeb, tom qab ntawd nws yog degreased thiab qhuav.

Tam sim no koj yuav tsum tau sib sau ua ke ntawm nws tus kheej. Rau nws, peb ua ntej ntawm tag nrho cov xav tau ib lub hwj chim qhov chaw uas tsim 12 V thiab 1 A ntawm cov zis. Lub roj teeb lossis lub charger rau nws zoo meej. Tom ntej no, koj yuav tsum tau ua ib tug zinc electrode. Qhov no tuaj yeem yog ib qho zoo tib yam ntawm zinc (phaj, pas nrig), lossis rooj plaub (iav) los ntawm cov roj teeb alkaline. Qhov kev xaiv tom kawg yog qhov zoo dua thiab yooj yim dua. Cov electrode yuav tsum tau muab qhwv nrog ib daim ntaub qhwv hauv ob peb txheej thiab txuas nrog lub davhlau ya nyob twg zoo ntawm lub hwj chim. Nyob rau tib lub sijhawm, nws tsis raug tso cai tias cov ntaub qhwv uas koj qhwv lub zinc pas nrig lossis phaj tuaj rau hauv kev sib cuag nrogterminal.

Cov xaim tsis zoo los ntawm lub zog hluav taws xob txuas nrog lub cev lub tsheb. Tsis tas li ntawd, txhua yam koj xav tau yog dip lub improvised electrode rau hauv kev daws teeb meem thiab maj mam tsav nws hla saum npoo kom kho. Thaum lub sij hawm tus txheej txheem no, zinc particles yuav nyob rau hauv cov hlau nyob rau hauv ib tug nyias txheej, tsim ib tug tiv thaiv txheej. Yog tias txoj haujlwm ua tiav, thaj chaw kho yuav muaj qhov kev ntxhib los mos ntawm cov xim teeb txho.

Thaum kawg ntawm txheej txheem galvanizing, qhov chaw yog ntxuav nrog cov tshuaj ntsev ntawm lub rooj ntsev thiab qhuav. Nyob rau hauv lub neej yav tom ntej, nws tuaj yeem pleev xim thiab pleev xim.

Qee yam muaj txiaj ntsig

Thaj chaw yuav tsum tau ua tib zoo ntxuav thiab xuab zeb nrog cov xuab zeb zoo kom nws qhov chaw tsis pom qhov grooves.

Qhov zoo electrode cable lossis hlws ris yuav tsum tsis txhob raug tso cai los rau hauv kev sib cuag nrog electrolyte.

Yuav tsum tau yaug nrog dej qab zib lossis lwm yam tshuaj alkaline. Qhov no yog tib txoj kev uas yuav neutralize acid residues. Txwv tsis pub, rov tshwm sim ntawm cov txheej txheem corrosion yog ua tau.

Lub sijhawm kuaj xyuas qhov xwm txheej ntawm daim ntaub ntawm electrode. Nyob rau hauv chav kawm ntawm kev ua hauj lwm, nws yuav maj mam hlawv, yog li reel nws raws sij hawm.

Ua txhua yam ua haujlwm sab nraum zoov lossis hauv qhov chaw muaj cua zoo, saib xyuas kev nyab xeeb. Tsis txhob cia cov kua qaub los rau hauv cov tawv nqaij los yog kev sib cuag ntawm hydrogen tso tawm nrog tshav kub.
