Kev sib piv zoo ntawm hluav taws xob cua sov tube electroplating thiab kub-dip galvanizing: Zinc txheej ntawm kub-dip galvanizing txheej txheem

2. Muab piv rau kub-dip galvanizing, txheej txheej galvanized ntawm cov txheej txheem kub-dip galvanizing yog siv rau lub sij hawm ntev sab nraum zoov los tiv thaiv corrosion txheej ntawm hlau. Cov txheej txheem no yog siv rau cov hlau loj loj (cov kav hlau xa mus, engineering steel qauv, thiab lwm yam) galvanizing thiab tiv thaiv corrosion, thiab tsis tuaj yeem nug. Txawm li cas los xij, ntawm qhov kub-dip galvanizing ntawm fasteners siv sab nraum zoov, kev siv cov txheej txheem hauv tsev feem ntau yog kev siv phau ntawv, ua ke nrog cov yam ntxwv ntawm cov txheej txheem kub-dip galvanizing, piv nrog cov yam ntxwv ntawm cov txheej txheem galvanizing, muaj qhov zoo thiab qhov tsis zoo ntawm cov txheej txheem galvanizing. kev siv cov txheej txheem. Piv txwv li, thaum kub-dip galvanizing yog siv rau gaskets thiab me me qhov chaw, qhov chaw yog nquag adhesion, thiab thaum plating threaded qhov chaw, molten zinc txheej yuav thaiv cov xov, thiab cov txiv ntseej yuav tsum tau plated thiab rov buckled; Cov pa luam yeeb, plua plav, thiab hlau kub vapor muaj kuab paug yog qhov hnyav, thiab cov txheej txheem galvanizing tsis muaj qhov tsis txaus. Tsis tas li ntawd, qhov saum npoo ntawm cov txheej txheem galvanizing yog smoother thiab ci dua li ntawm kub-dip galvanizing; Rau kev tiv thaiv ib puag ncig, nws yog qhov sib piv cov txheej txheem ntxuav.

Functionally, kub dip galvanizing txheej txheem ntawm high-temperature melting yuav ua rau annealing thiab softening ntawm nto ntawm quenched high-strength fastening qhov chaw, xws li 8.8 qib high-strength steel highway guardrail fasteners. Thaum siv kub dip galvanizing, tensile xeem ua raws li cov qauv kev qhia txog cov khoom tsis tsim nyog lossis tsis ruaj khov. Mechanical galvanizing tsis ua rau annealing cuam tshuam rau ntawm qhov chaw ntawm quenched steel qhov chaw nyob rau hauv chav tsev kub.

Cov txheej txheem galvanized kuj muaj cov haujlwm ntawm kev tiv thaiv atmospheric acid los nag. Los ntawm kev sim thiab sib piv, nws cov tshuaj tua kab mob acid nag muaj peev xwm yog peb zaug ntawm cov txheej kub-dip galvanized. Piv txwv li, yog tias cov khoom siv galvanized thiab kub-dip galvanized qhov chaw nrog tib txheej tuab yog immersed nyob rau hauv 10 feem pua ​​~ 15 feem pua ​​dilute sulfuric acid tov, lawv cov kua qaub corrosion lub sij hawm yuav yog peb zaug tom qab kub-dip galvanized qhov chaw. Cov kua qaub los tiv thaiv kev ua haujlwm no yuav yog qhov tseem ceeb tshwj xeeb rau sab nraum zoov lub zog ntauwd fastening qhov chaw nrog cov kua qaub los nag hauv huab cua.
