Galvanized txheej ntawm cov hlau raug puas ntsoog tas li thaum vuam, txiav, thiab thauj. Lawv yuav tsum tau kho, lossis lwm yam kev puas tsuaj yuav ua rau xeb. Muaj peb txoj hauv kev tshwj xeeb los kho txheej.
Cov kauj ruam
Txoj Kev 1 ntawm 3: Kho Siv Zinc Raws Alloys
Kauj Ruam 1. Nco ntsoov tias koj muaj Cov Lus Qhia Galvanite thiab nco ntsoov nyeem lawv
Kauj Ruam 2. Ua ntej ntxuav niam txiv cov hlau
Siv cov khoom no: ntaub ntaub, txhuam txhuam hlau, txhuam xuab zeb, thiab lwm yam. Txhawm rau kom ua tiav qhov ua tau zoo, qhov kev npaj saum npoo yuav tsum nthuav mus rau ib puag ncig tsis muaj kev puas tsuaj galvanized txheej. Ua txhaum txheej txheej oxide los ntawm kev kub ntxhov yog qhov tseem ceeb rau kev txhim kho kev kho cua sov. Yog tias thaj chaw yuav raug kho suav nrog cov vuam, tag nrho cov weld flux residue thiab weld spatter yuav tsum tau tshem tawm los ntawm cov txhuam txhuam, chipping, sib tsoo lossis ntsuas lub zog.
Kauj Ruam 3. Siv lub nplaim hluav taws, rab phom cua sov lossis cov hlau txuas los ua kom sov cov niam txiv kho qhov chaw kom tsawg kawg 600 ° F/315 ° C
Tsis txhob ua kom sov qhov chaw tshaj 750 ° F/400 ° C lossis tso cai rau ib puag ncig galvanized txheej kom hlawv. Yog tias koj siv lub nplaim taws ncaj qha, cia nws txav mus. Cov nplaim hluav taws ncaj qha nyob ntawm thaj chaw kho yuav zoo li ua kom sov ntau dua. Hlau txhuam qhov saum npoo thaum cua sov. Pre-flux siv flux yog tias muaj teeb meem adhesion. NCO TSEG: Ntau daim ntawv thov tsis xav tau dej ntws.
Kauj Ruam 4. Tuav lub qhov taub 4 txog 6 ntiv tes (10.2 txog 15.2 cm) kom deb ntawm niam txiv hlau
Yog tias nws yog qhov yuav tsum tau siv cov nplaim taws ncaj qha mus rau tus pas nrig kom nws pib, rub lub qhov taub rov qab txawm tias deb dua ntawm qhov chaw ua haujlwm thiab kom nws txav mus.
Kauj Ruam 5. Laub tus pas hla qhov chaw kom muab muag, kom txog thaum nws pib ntws
Thaum tus pas nrig ntws mus, tsis txhob siv lub cua sov. Tso qhov xav tau tuab ntawm galvanizing kho pas. Tus txhuam hniav tsis xeb ua haujlwm tau zoo los nthuav cov laug thiab xyuas kom nws ua raws. Yog xav tau txheej txheej ntxiv, rub tus pas hla qhov chaw mus.
Nqa cov cua sov rov qab tsuas yog ua kom lub ntsej muag, tsis yog pas nrig, kub txaus los thawb tus neeg muag khoom ib ncig mus rau qhov koj xav tau
Kauj Ruam 6. Muab cov tshuaj kho rau hauv cov xim tsis muaj xim tsis zoo
Qhov kev saib xyuas ntau tshaj plaws hauv kev kho galvanized yog tsis ua rau plaub hau galvanizing kho cov txheej txheej mus rau hauv cov xim tsis xeb. Yog tias lawv tsis koom nrog qhov tuab txaus los ua ib qho thaiv tsis sib haum (tawv nqaij), kev xeb yuav tshwm sim qhov uas lawv ntsib.
Kauj Ruam 7. Saib xyuas qhov tso nyiaj solder
Lub lauj kaub yuav tsum tau ua kom zoo. Tsis txhob ua kom sov dhau, tus pas nrig yuav yaj yog tias kub dhau, tab sis yuav tsis sib txuas kom raug. Tshaj tawm cov nyiaj tso nyiaj sib npaug sib npaug ntawm thaj chaw kho. Tus txhuam hniav stainless hlau ua haujlwm zoo rau cov kauj ruam no.
Kauj Ruam 8. Yog tias koj tsum tsis txhob siv cov tooj dag thiab xav siv cov laug ntau dua lossis ntws tawm qhov tso nyiaj ntau dua, cia thaj chaw txias qis dua qhov kub thiab ua kom sov dua
Cov txheej txheej uas twb muaj lawm yuav pab cov txheej txheem kev sib txuas, txawm hais tias yuav ntxiv cov kab laug sab lossis tsuas yog ntws tawm qhov tso nyiaj dhau los.
Yog tias lub sijhawm tseem ceeb tau dhau mus txij li txheej txheej txheej qub tau siv, ua ntej ntxuav thaj chaw kho dua kom tshem tawm cov txheej txheej oxide uas yuav cuam tshuam rau kev sib khi. Ib zaug ntxiv, txhuam cov hlau tsis xeb ua haujlwm zoo rau theem no
Kauj Ruam 9. Txhim kho thaj chaw thiab tshem tawm cov kab laug sab dhau nrog xaim txhuam
Kauj Ruam 10. Rov ua cov kauj ruam no txhawm rau txhim kho txheej txheej tiv thaiv ntxiv
Kauj Ruam 11. Sau cov khoom hauv qab no:
-
Common Zinc raws cov hlau nplaum
- Zinc-Cadmium-Kub ua kua-509 ° F-600 ° F (265 ° C-316 ° C)
- Tin-Zinc-Lead-Kub ua kua-350 ° F-550 ° F (177 ° C-288 ° C)
- Tin-Zinc-Tooj-Kub kub-390 ° F-570 ° F (200 ° C-300 ° C)
- Propane lossis MAP Roj teeb tau pom zoo
- Stainless hlau los yog hlau txhuam
Txoj Kev 2 ntawm 3: Kho Cov Txheej Txheem Siv Xim Muaj Zinc Plua Plav
Kauj Ruam 1. Kho qhov puas tsuaj kub dip galvanized txheej
- Cov xim no muaj cov plua plav zinc thiab tsim nyog rau kev kho cov xim txheej xim puas tau muab cov xim uas muaj hmoov av zinc yuav tsum muaj cov hmoov av zinc ntau txog li 65-69% lossis siab dua 92% hauv zaj duab xis qhuav.
- Kho qhov chaw nrog cov xim uas muaj hmoov av zinc yuav tsum huv, qhuav, tsis muaj roj, roj, xim ua ntej, xeb, thiab/lossis xeb.
- Ntxuav qhov chaw raws li qhov xav tau ntawm SSPC SP10 (ze-dawb). Qhov xwm txheej twg tsis tso cai rau siv lub tshuab ua kom tawg lossis lub zog siv, tom qab ntawd cov cuab yeej siv tes yuav raug siv. Kev tu yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm SSPC SP2 (tshem tawm xeb xoob, ntsuas nplai, lossis pleev xim rau qib uas tau teev tseg, los ntawm tes chipping, tawg, txhuam, thiab xaim txhuam hniav)
- Txhawm rau kom ntseeg tau tias cov txheej txheej zoo dua tuaj yeem cuam tshuam, kev npaj saum npoo yuav tsum txuas mus rau hauv cov xim tsis muaj txheej txheem.
- Yog tias thaj chaw/thaj chaw yuav raug kho suav nrog cov vuam, ua ntej tshem tag nrho cov weld flux seem thiab weld spatter los ntawm blasting, chipping, sib tsoo lossis ntsuas lub zog, thiab lwm yam.
Kauj Ruam 2. Tshuaj tsuag lossis txhuam-siv cov xim uas muaj hmoov av zinc rau ntawm qhov chaw npaj/thaj chaw
Thov pleev xim raws li cov chaw tsim khoom pom zoo hauv ib daim ntawv thov siv ntau daim ntawv hla mus ua kom cov zaj duab xis qhuav tuab raws li tau teev tseg.
Kauj Ruam 3. Tso sijhawm kho kom zoo ua ntej xa khoom lossis cuam tshuam cov khoom kho rau kev pabcuam
Kev kho yuav tsum ua raws li cov chaw tsim khoom pom zoo.
- Thickness yuav tsum txaus thiab/lossis raws li tau hais tseg
- Nco ntsoov tias Zinc nplua nuj xim tsis suav tias yog txheej txheej galvanized. Kuj hu ua "txias galvanizing"
Kauj Ruam 4. Tau zinc nrog cov xim
Nws los hauv tshuaj tsuag, lossis txhuam ntawm qhov sib txawv.
Txoj Kev 3 ntawm 3: Kho Nrog Txau Zinc (Hlau)
Kauj Ruam 1. Kho qhov kub poob galvanized txheej puas,
- Txoj kev no tsis yog rau daim ntawv thov thiab tsis tuaj yeem siv hauv thaj chaw. Txoj hauv kev no cuam tshuam nrog kev thov txheej txheej zinc los ntawm kev txau cov nplaim kom kho nrog cov dej me me ntawm cov hlau yaj uas siv hlau, hlua, lossis txheej txheem hmoov. Yuav tsum hu rau lub khw hlau.
- Cov chaw uas yuav tsum tau kho los ntawm cov txheej txheem hlau hlau yuav tsum huv, tsis muaj av, roj, thiab cov khoom xeb, thiab qhuav.
- Yog tias thaj chaw/thaj chaw uas yuav kho tau suav nrog cov hlau txuas, ua ntej tshem tag nrho cov dej ntws tawm thiab cov pa tawg ntawm qhov loj lossis hom uas tsis tuaj yeem raug tshem tawm los ntawm kev tu lub tshuab tawg lossis siv lub tshuab, uas yog chipping, sib tsoo lossis lub zog ntsuas.
Kauj Ruam 2. Blast ntxuav qhov saum npoo kom rov kho dua raws li qhov yuav tsum tau ua ntawm SSPC SP5 (hlau dawb)
Kauj Ruam 3. Txhawm rau kom ntseeg tau tias txheej txheej zoo dua qub tuaj yeem cuam tshuam, kev npaj saum npoo yuav tsum nthuav mus rau ib puag ncig, tsis muaj txheej txheej galvanized tsis puas
Kauj Ruam 4. Thov txheej txheej los ntawm kev siv hlau txau rab phom rab phom nrog cov xaim hlau lossis zinc hmoov
Siv cov tshuaj tsuag tsuag kom sai li sai tau tom qab npaj saum npoo av thiab ua ntej pom qhov tsis zoo ntawm qhov chaw tau tshwm sim.
- Qhov saum npoo ntawm cov tshuaj txau yuav tsum yog ib qho kev ntxhib los mos, tsis muaj cov pob, qhov chaw ntxhib thiab ua raws cov xoob xoob.
- Qhov tuab tuab ntawm cov tshuaj tsuag zinc txheej yuav tsum txaus thiab raws li tau teev tseg.
