Yuav ua li cas kho zinc bursting thaum lub sij hawm galvanizing?
Zinc bursting feem ntau tshwm sim los ntawm qhov tsis zoo flux piv, zinc ntsev cov ntsiab lus ua rau ntsev zaj duab xis deliquescence, thiab hydroxide decomposition ua roj. Nws kuj tseem tuaj yeem tshwm sim los ntawm cov roj av sab hauv khiav thiab hlawv cov flux thaum lub workpiece muab tso rau hauv lub lauj kaub. Qhov sib piv flux yuav tsum tau hloov kho, thiab qhov tsim nyog ntawm ammonium chloride yuav tsum tau ntxiv thaum lub workpiece muab tso rau hauv lub lauj kaub.
Vim li cas cov txheej tsis sib npaug tshwm sim thaum electroplating?
Uneven composition of the electroplating solution, unreasonable current density distribution, improper rack design, or inconsistent surface pretreatment of the workpiece can be addressed by strengthening the stirring and filtration of the plating solution, optimizing the current distribution and rack design, and standardizing the pretreatment process.
Yog vim li cas threaded kev twb kev txuas yog to taub thaum lub sij hawm galvanized yeeb nkab installation?
Cov xov uas xoob dhau, nruj dhau, tawg, lossis tsis muaj xov; Kev siv tsis raug ntawm cov ntaub ntawv sealing los yog qhwv tsis raug. Lub tshuab threading tsim nyog yuav tsum tau siv los xyuas kom meej 7-9 cov xov tiav, thiab cov ntaub ntawv sib khi xws li PTFE daim kab xev yuav tsum tau qhwv clockwise.
Yuav ua li cas kom tsis txhob muaj kev pheej hmoo ntawm cov khoom siv tsis zoo thaum lub sij hawm galvanized yeeb nkab installation? Thaum tuaj txog ntawm cov ntaub ntawv, tshuaj xyuas qhov smoothness thiab txheej txheej, kom ntseeg tau tias tsis muaj qhov ploj los yog tev. Siv lub thickness gauge los xyuas cov zinc txheej thickness. Xaiv cov kav dej uas tsim nyog rau kev ntsuas siab rau daim ntawv thov, tsis txhob sib xyaw cov kav dej thiab cov kav dej.
Vim li cas qhov kev ntsuas dej siab tsim nyog tom qab kev teeb tsa galvanized yeeb nkab? Nws ua li cas?
Kev ntsuas dej siab pab txheeb xyuas qhov muaj peev xwm xau. Kev ntsuas siab yog 1.5 npaug ntawm qhov tsim siab tab sis tsis pub tsawg dua 0.6 MPa. Tom qab sau nrog dej thiab purging cua, nce lub siab thiab stabilize nws rau 10 feeb. Lub siab poob siab tsis ntau tshaj 0.02 MPa tau txais, thiab cov yeeb nkab raug suav hais tias yog 合格 (tsim nyog) yog tias tsis muaj qhov xau tshwm sim thaum lub siab poob rau lub siab ua haujlwm.
