Dab tsi yog galvanized tsheb lub cev: cov lus piav qhia thiab cov npe ntawm cov qauv

Corrosion yog rightfully suav hais tias yog tus yeeb ncuab tseem ceeb ntawm hlau. Yog tias cov hlau saum npoo tsis tiv thaiv, ces nws ntog sai. Qhov teeb meem no tseem cuam tshuam rau lub cev tsheb. Cov xim pleev xim tiv thaiv, tab sis nws tsis txaus. Ib qho ntawm cov kev daws teeb meem yog qhov tshwm sim ntawm lub cev, uas cuam tshuam ntev nws lub neej kev pab. Qhov no tsis yog qhov yooj yim thiab pheej yig tshaj plaws ntawm kev tiv thaiv, yog li cov chaw tsim khoom muaj cov txheej txheem sib txawv rau galvanizing txoj kev.

Dab tsi yog galvanizing

Cov txheej txheem oxidation tshwm sim ntawm cov hlau tsis muaj kev tiv thaiv. Oxygen nkag mus tob dua thiab tob rau hauv cov hlau, maj mam rhuav tshem nws. Zinc kuj oxidizes rau saum huab cua, tab sis ib zaj duab xis tiv thaiv ua rau ntawm qhov chaw. Zaj duab xis no tiv thaiv cov pa tawm rau sab hauv, txiav cov pa oxidation.

Yog li, zinc-coated puag yog zoo tiv thaiv corrosion. Raws li cov txheej txheem ua khoom siv, lub cev galvanized tuaj yeem dhau ntev txog 30 xyoo.

Pab AvtoVAZ tau pib siv qee qhov chaw ntawm lub cev nkaus xwb hauv 1998.

Tshuab thiab hom ntawm galvanizing

Cov xwm txheej tseem ceeb rau galvanizing yog qhov huv thiab qib nto uas yuav tsis raug rau nyom thiab cuam tshuam. Hauv kev tsim kho tsheb, ntau txoj kev ua haujlwm tau siv:

• kub-dip galvanized (cua sov);
• galvanic;
• txias heev.

Cia peb xav txog thev naus laus zis thiab qhov tshwm sim ntawm txhua qhov ntawm cov txheej txheem hauv ntau dua.

Kub

Qhov no yog kev nyab xeeb tshaj plaws thiab zoo tshaj plaws ntawm galvanizing. Lub cev lub cev tau raug raus tag nrho rau hauv ib lub taub ntim ntawm cov roj ntsha zinc. Cov kua kub tau txog 500 ° C. Qhov no yog li cas cov ntshiab zinc reacts nrog oxygen mus tsim zinc carbonate rau saum npoo, uas nres kev ua haujlwm. Zinc npog tag nrho lub cev los ntawm txhua sab, nrog rau txhua qhov sib koom thiab nqaws. Qhov no tso cai rau cov kws kho tsheb muab lub cev tiv thaiv mus txog 15 xyoos.

Hauv lwm qhov chaw, seem ua tiav hauv txoj kev no tuaj yeem ntev 65-120 xyoo. Txawm hais tias cov xim pleev xim puas tsuaj, lub zinc txheej pib ua rau oxidize, tab sis tsis yog siv cov hlau. Lub tuab ntawm tiv thaiv txheej yog 15-20 microns. Hauv kev lag luam, qhov tuab ncav cuag li 100 microns, ua cov ntu ua ntu zus mus ib txhis. Tsis tas li, khawb thaum lub sijhawm ua haujlwm kub yuav ua rau tus kheej nruj.

Audi yog thawj tus siv thev naus laus zis no ntawm Audi A80. Tom qab txoj kev no tau siv los ntawm Volvo, Porsche thiab lwm yam. Txawm hais tias tus nqi siab ntawm kub-dip galvanizing, txoj kev siv tsis yog tsuas yog ntawm cov tsheb hwm, tab sis kuj ntawm cov qauv nyiaj txiag. Piv txwv li, Renault Logan lossis Ford Focus.

Kev tshuab hluav taws xob

Hauv cov txheej txheem electroplating, zinc siv rau cov hlau siv hluav taws xob. Lub cev muab tso rau hauv ib lub taub ntim nrog zinc-muaj electrolyte. Txoj kev no cawm tau ntawm kev siv cov tshuaj yeeb yaj kiab, txij li cov zinc npog cov hlau nrog ib qho kiag li txawm txheej. Lub txheej tuab ntawm cov zinc txheej thaum lub sijhawm galvanic txoj kev yog 5-15 microns. Cov neeg tsim khoom muab qhov lav txog 10 xyoo.

Txij thaum electroplating tsis muaj kev tiv thaiv tsawg, ntau lub chaw tsim khoom txhim kho kom zoo ntawm cov hlau, ua kom tuab ntawm zinc txheej, thiab ntxiv ib txheej ntawm cov ntawv primer.

Txoj kev no yog siv los ntawm cov khoom lag luam xws li Skoda, Mitsubishi, Chevrolet, Toyota, BMW, Volkswagen, Mercedes thiab qee yam.

Pab Txij li xyoo 2014, UAZ tau siv cov ntawv galvanic galvanizing rau Patriot, Tus Saib Xyuas, Phom qauv. Txheej tuab 9-15 microns.

Mob khaub thuas

Nws yog txoj hauv kev yooj yim thiab pheej yig los tiv thaiv lub cev los ntawm kev xeb. Nws tau siv rau ntau qhov qauv peev nyiaj, suav nrog Lada. Hauv qhov no, cov hmoov zinc ntau tawg tau thov los ntawm txau. Cov ntsiab lus zinc ntawm txheej yog 90-93%.

Mob khaub thuas galvanizing yog dav siv los ntawm Suav, Kauslim thiab Lavxias tsheb tuam ntxhab. Ib nrab txias galvanizing kuj tseem siv, thaum tsuas yog ib feem ntawm cov seem lossis tsuas yog ib sab ua tiav. Tom qab ntawd xeb tuaj yeem pib, piv txwv li, los ntawm sab hauv, txawm hais tias lub tsheb nws tus kheej zoo rau sab nraud.

Pros thiab cons ntawm galvanizing txoj kev

Txhua ntawm cov txheej txheem piav qhia ntawm kev thov tiv thaiv zinc muaj nws cov pluses thiab minuses.

• Kub dip galvanizing muaj kev tiv thaiv zoo heev, tab sis ib txheej txawm yuav tsis tiav. Tsis tas li, xim ntawm lo yog grey thiab matte. Zinc muaju yuav tuaj yeem txiav txim siab.
• Cov txheej txheem electroplating tiv thaiv me ntsis tsawg dua, tab sis ib sab ci thiab ci. Nws tseem tau txais txiaj ntsig los ntawm kev lag luam kev pom.
• Ntxiv rau kev ua txias txias tsuas yog pheej yig, tab sis qhov no zoo rau cov tuam txhab tsim khoom, txawm hais tias nws tso cai rau koj los txo tus nqi ntawm lub tsheb.

Yuav ua li cas thiaj paub tias lub cev tsheb galvanized lossis tsis yog?

Yog tias koj xav paub seb lub cev puas yog zinc-coated lossis tsis, yog li thawj zaug ua yog saib cov ntaub ntawv pov thawj ntawm lub tsheb. Yog tias koj tsis pom lo lus "zinc" nyob ntawd, tsis muaj kev tiv thaiv xeb. Txawm hais tias feem ntau cov tuam txhab tsim tsheb siv zinc plating, cov lus nug tsuas yog hom kev thiab thaj chaw ntawm kev kho. Piv txwv li, ntawm Lada Priora txog 2008, tsuas yog 28% ntawm lub cev tau galvanized, ntawm VAZ 2110 tsuas yog 30% ntawm lub cev tau npog. Thiab qhov no nrog rau cov txheej txheem ua txias. Feem ntau, Suav tuam ntxhab txuag ntawm kev kho zinc.

Koj kuj tuaj yeem tshawb txog cov ntaub ntawv hauv Is Taws Nem ntawm cov ntaub ntawv tso cai. Muaj ntau lub rooj yuav tsum pom. Koj tuaj yeem pom ib qho ntawm cov kawg ntawm kab lus no.

Yog tias koj pom cov kab lus "tag nrho galvanized", ces qhov no hais txog galvanic lossis kub txoj kev ntawm kev ua tiav lub cev tag nrho. Xws li lub hauv paus yuav kav ntau xyoo tsis muaj xeb.

Qee cov qauv nrov nrog lub cev galvanized

Raws li tau hais, tag nrho galvanization tseem siv tau rau ntau cov qauv nyiaj. Ntxiv mus peb yuav qhia koj qee cov qauv ntawm cov tsheb nrog tshuaj tiv thaiv corrosion uas nrov heev hauv Xos Viav thiab txawv teb chaws.

• Ntog Logan... Lub cev ntawm cov npe nrov no muaj ntau yam tsis kam tiv thaiv corrosion. Txij xyoo 2008, nws tau ua tiav tag nrho galvanized.
• Chevrolet lacetti... Ib lub tsheb pheej pheej yig, tab sis nrog cov tshuaj tiv thaiv kom tsis muaj xeb. Kev siv fais fab pleev.
• Audi A6 (C5) Lub tsheb... Txawm hais tias 20-xyoo tsheb nyob rau hauv chav kawm no saib zoo ua tsaug nyob rau hauv loj feem rau tag nrho galvanization. Ib yam tuaj yeem hais tau rau txhua lub tsheb Audi. Qhov chaw tsim khoom no siv cov kub kub duav coj kub.
• Ford Focus... Ib tus neeg tiag tiag lub tsheb nrog zoo tiv thaiv corrosion. Txhua lub cev hauv thaj tsam no tau ua haujlwm kub.
• Mitsubishi lancer... Lub tsheb ruaj khov thiab txhim khu kev qha, uas yog tus hlub nyob Xos Viav thiab txawv teb chaws. Nws tsis xeb vim nws txheej 9-15 micron zinc txheej.

Yeeb yaj duab zoo

Txheeb xyuas cov txheej txheem ntawm galvanizing lub cev nrog koj tus kheej txhais tes hauv ib qho kev kawm hauv qhov yeeb yaj kiab hauv qab no:

Galvanizing lub cev muab cov tshuaj los tiv thaiv corrosion, tab sis muaj qhov sib txawv hauv cov txheej txheej. Lub cev yuav tsis nyob ntev ntev yam tsis muaj kev tiv thaiv, qhov ntau yog 7-8 xyoo. Yog li no, thaum muas lub tsheb, koj yuav tsum nco ntsoov them lub sijhawm rau lub sijhawm.

Cov Lus Nug thiab Cov Lus Teb:

Chevrolet nrog galvanized lub cev yog dab tsi? Aveo, Blazer (3,4,5), Camaro (2-6), Captiva, Malibu, Cruze (1, J300 2009-2014, 3 2015-2021), Lacetti (2004-2013), Lanos (2005-2009) , Niva (2002-2021)...

Yuav ua li cas los txiav txim seb lub cev yog galvanized los yog tsis? Yog tias ua tau, koj tuaj yeem tshawb xyuas VIN code (ntau lub tuam txhab qhia cov cai rau lub cev galvanized). Ntawm qhov chaw ntawm cov nti - qhov tseeb tshaj plaws los xyuas seb qhov muaj galvanized.

Dab tsi ntawm SUVs nrog lub cev galvanized? Nov yog cov npe uas nws cov qauv tsheb tuaj yeem tau txais lub cev galvanized: Porsche, Audi, Volvo, Ford, Chevrolet, Opel, Audi. Tib cov qauv hauv ntau xyoo sib txawv yuav txawv ntawm hom kev tiv thaiv lub cev.
