1, cov khoom ntawmloj galvanized hlau: zinc ingot: yuav tsum tsis txhob qis dua qhov tsis muaj.- zinc teev nyob rau hauv GB470;Sulfuric acid: qib 1 concentrated sulfuric acid raws li GB534;Hydrochloric acid: qib 1 concentrated hydrochloric acid raws li GB534;Ammonium chloride: yuav tsum ua raws li cov kev cai ntawm GB2946 ammonium chloride qib 1.
2, zoo li: txheej nto nruam thiab siv tau, du;Kev teeb tsa thiab kev sib txuas ntawm cov khoom plated tsis tso cai kom muaj ntws dai, ntws los yog yaj.Qhov saum npoo ntawm cov khoom plated yuav tsum tsis txhob muaj qhov tsis xws luag xws li cov dej xau plating thiab dew hlau, tab sis qhov tsis xws luag raug tso cai nyob rau hauv cov xwm txheej hauv qab no;Cov dej ntws tawm yog tsawg dua 0.5mm txoj kab uas hla;Txawm hais tias qhov loj ntawm daim plating, qhov chaw hauv lub pas dej plating thaj tsam ntawm 0.5mm- Imm txoj kab uas hla yuav tsum tsis pub tshaj 3 cov ntsiab lus ib square centimeter, thiab tag nrho cov chaw nyob rau hauv lub plating daim yuav tsum tsis txhob ntau tshaj 10 ntsiab lus;Hauv qhov tsis sib txuas lossis tsis yog qhov sib txuas, qhov siab tsis tshaj 1.5 hli ntws dai drip lossis slag;Muaj qhov caws pliav thaum plating qhov chaw sib cuag nrog cov cuab yeej dai thiab cov cuab yeej ua haujlwm, tab sis tsis muaj dew hlau.
3. Zinc adhesion thiab zinc txheej thickness: thaum lub thickness ntawm plated seem yog 3mm ~ 4mm, zinc adhesion yuav tsum tsawg tshaj li 460g / m, uas yog, qhov nruab nrab thickness ntawm zinc txheej yog tsis tsawg tshaj li 65um;Thaum lub thickness ntawm plated yog ntau tshaj 4 hli, zinc adhesion yuav tsum tsis txhob tsawg tshaj li 610g / m, uas yog, qhov nruab nrab thickness ntawm zinc txheej yog tsis tsawg tshaj li 86um;Txheej uniformity,galvanizedtxheej yog ib txwm sib xws nrog tooj liab sulfate tov kuaj etching tsib zaug tsis muaj dew hlau;Txheej adhesion, zinc txheej ntawm plated qhov chaw yuav tsum ruaj khov ua ke nrog cov hlau yooj yim nrog lub zog adhesion txaus, tom qab rauj xeem tsis poob, tsis convex.
4, yuav tsum tau plated yuav tsum: yuav plated nto yuav tsum du, tsis muaj pickling txoj kev yuav tsis tshem tawm cov pa phem, xws li roj nyeem, roj, cement, asphalt thiab lwm yam teeb meem impurities;Tag nrho cov welds ntawm cov tswv cuab welded yuav tsum raug kaw yam tsis muaj cua;Cov kav dej thiab cov thawv ntim khoom yuav tsum muaj qhov rau qhov tso pa tawm thiab zinc kom tsawg;Lub workpiece yuav tsum tiav welded steel yeeb nkab tsis muaj xov, yog tias xov yuav tsum tau tiv thaiv.Txoj kev kuaj: Zinc adhesion yog ntsuas los ntawm magnetic thickness gauge thiab zinc txheej thickness yog ntsuas ncaj qha.Lub uniformity ntawm txheej yog txiav txim los ntawm tooj liab sulfate tov etching xeem txoj kev.
5, stretching txoj kev: zinc txheej adhesion, zinc txheej thickness, zinc txheej uniformity, adhesion yog sib cav, coj tus qauv thiab cov khoom nyob rau hauv tib txoj kev mob galvanized;Ua qhov kev xeem, tsis ua raws li cov cai ntawm cov qauv no rau cov khoom tsis tsim nyog;Cov khoom lag luam sampling test method, thawj zaug yuav tsis raug, tom qab ntawd raws li cov kev cai cuam tshuam cov qauv kuaj, yog tias tseem tsis tsim nyog, txiav txim siab cov khoom lag luam no tsis tsim nyog.Tus neeg soj ntsuam lub txhab nyiaj: Cov khoom tsim nyog plated tsuas tuaj yeem teev nyob rau hauv lub chaw ua haujlwm tsim nyog tom qab tau lees paub los ntawm tus neeg soj ntsuam puv sijhawm;Cov khoom tsim nyog yuav tsum tau stacked zoo raws li ntau yam specifications.
