DX54D Galvanized hlau
DX54D daim ntawv phaj yog tsim los siv cov txheej txheem kub -dip galvanizing. Zinc txheej txheej metallurgical nto ntawm hlau thaum nws yog immersed nyob rau hauv lub melted hlau. Qhov no corrosion-dawb, ntshiab, qhuav nto tso cai rau txhua yam haujlwm ua rau nws. Tom qab ntawd lub vuam yog nyob rau hauv cov huab cua kom tsis txhob overheating, thiab kom txias daim ntawv sai sai, cov squeegees raug txo los yog muab tso tawm. Cov txheej txheem no tsis cuam tshuam rau cov khoom tsim tawm tab sis ua rau nws muaj txiaj ntsig ntau dua hauv cov xwm txheej sib txawv.

Kub-Dip Galvanizing txheej txheem
Cov hlau yog immersed nyob rau hauv molten zinc nyob rau hauv kub dip galvanizing los tsim ib lub tsho tiv no. Ua ntej pib, kuv ntxuav cov hlau saum npoo, vim qhov no yuav tso cai rau kev sib koom ua ke ntawm ob qhov chaw: zinc thiab coated steel. Thaum tsim nyog coated, cov hlau yog sab laug kom txias, tom qab ntawd kuv tshuaj xyuas lub txheej los xyuas tias nws tau raug them nrog zinc tag nrho ntawm nws qhov chaw. Lub tsho tiv no siv rau hauv txoj kev no kom ntseeg tau tias cov khoom siv tau zoo ntawm cov hlau tsis cuam tshuam los ntawm xeb lossis chipping.
Ua kom muaj kev tswj xyuas zoo hauv kev tsim khoom
Muaj cov qauv zoo nruj hauv cov txheej txheem tsim khoom suav nrog kev siv cov txheej txheem zoo ib yam. Yog li, tsib yam tseem ceeb uas ua kom muaj kev tswj xyuas zoo hauv cov txheej txheem kub -dip galvanizing yog muab hauv qab no;
Npaj Qhov Nto
Kev tu kom txaus ntawm cov hlau nto thaum lub sij hawm sib txawv, xws li degreasing, pickling, thiab fluxing, tso cai rau kev ntub dej txaus ntawm cov hlau nrog zinc. Hauv kev xyaum ua engineering, ntau dua 20% ntawm cov lus tsis txaus siab qhia txog cov txheej txheem los ntawm kev npaj tsis txaus.
Tswj lub da dej kub
Kev tswj kom zoo ntawm kev ua haujlwm kub ntawm lub da dej nrog cov zinc molten, uas feem ntau yog nyob nruab nrab ntawm 830 thiab 860 Degrees F (443 thiab 460 degrees Celsius), yog tswj xyuas kom ntseeg tau tias cov tuab tuab ntawm txheej txheej, thiab cov geometry ntawm qhov tsis xws luag yog zam.
Interlayer soj ntsuam ntawm Txheej Thickness
Kev kuaj xyuas ib ntus ntawm cov zinc txheej txheej siv cov hlau nplaum thickness gauges lav kev ua raws li ASTM specifications yuav tsum tau ua kom tau raws li qhov xav tau ntev. Qhov pom zoo txheej thickness txawv ntawm 2.0 mill inches (50 microns) mus rau 5.0 mill inches (125 microns), nyob ntawm seb lub hom phiaj ntawm cov hlau.
Kev ntsuas dej noo
Xws li ib qho kev sim yog tsim nyog los ntsuas cov zinc txheej lub peev xwm ncav cuag yam tsis muaj kev puas tsuaj lossis detachment.
Kev xeem thaum kawg
Ib tug kws soj ntsuam kuaj xyuas qhov kawg ntawm cov khoom, nrhiav kev sib xws, pov thawj ntawm dripping, thiab smoothness feem ntau. Kev kuaj pom pom pab kom tsis txhob muaj qhov tsis zoo ntawm qhov chaw ua ntej xa cov hlau rau kev siv ntxiv; uas yog, kwv yees li 90% ntawm qhov tsis xws luag raug kuaj pom los ntawm txoj kev no.
Cov txheej txheem tswj kev ua tau zoo no xyuas kom meej tias cov hlau galvanized tsim yog ob qho tib si siv tau thiab txaus siab rau cov neeg siv khoom xav tau ntawm lwm cov kev lag luam; li no, yog haum rau lub hom phiaj.
