1, Txoj kev loj hlob ntawm phosphating technology
Txoj kev loj hlob ntawm phosphating technology tau dhau los ntawm ntau tshaj 100 xyoo ntawm keeb kwm txog niaj hnub no. Tau ntau tshaj 100 xyoo, phosphating tshuab tau hloov zuj zus los ntawm cov txheej txheem tshuaj lom neeg yooj yim mus rau cov thev naus laus zis thiab kev ua tiav; Phosphating cov neeg ua haujlwm kho mob tau hloov zuj zus los ntawm ib qho ntau yam mus rau ntau pua ntawm cov khoom; Txoj kev kho phosphating tau hloov zuj zus los ntawm qhov yooj yim immersion mus rau ntau hom xws li immersion, spraying, thiab spray immersion niaj hnub no; Daim ntawv thov kev siv tshuab phosphating kuj tau hloov zuj zus los ntawm tsuas yog tsom rau kev tiv thaiv hlau corrosion rau ntau yam xws li phosphating kev kho mob ua ntej hlau txheej, phosphating kev kho mob rau hlau hnav tsis kam, phosphating kev kho mob rau hlau tiv thaiv corrosion, thiab phosphating kev kho mob ua ntej hlau yas deformation ua.
Qhov kev kho phosphating ntxov tshaj plaws yog muab cov hlau (steel) qhov chaw rau hauv cov tshuaj phosphoric acid uas muaj cov ntaub ntawv hlau, ua kom sov cov tshuaj no kom kub kub, thiab tom qab 2.0 thiab 2.5 teev ntawm kev kho mob, tau ib txheej ntawm crystalline thiab ntom. phosphate txheej ntawm hlau nto. Cov tshuaj phosphoric acid no muaj cov ntaub ntawv hlau yog cov tshuaj phosphating ntxov tshaj plaws.
Tom qab ntawd, tib neeg txuas ntxiv txhim kho cov phosphating cov neeg ua haujlwm, feem ntau yog txo cov zaj duab xis-tsim kub thiab sijhawm. Los ntawm kev hloov cov mis, ntxiv ntau yam accelerators, thiab lwm yam, phosphating kev kho mob tuaj yeem nqa tawm hauv txhua lub xeev los ntawm chav sov mus rau boiling, thiab lub sij hawm kho phosphating tuaj yeem txo mus rau ob peb feeb kom tiav.
Tam sim no muaj ntau yam ntawm phosphating cov neeg ua haujlwm, uas tau pib ua serialized. Kev faib tawm los ntawm kev ua haujlwm kub: muaj cov tshuaj phosphating kub, nruab nrab kub phosphating cov neeg ua haujlwm, chav kub phosphating agents, thiab lwm yam; Muab faib los ntawm daim ntawv: muaj cov hmoov phosphating cov neeg ua haujlwm thiab cov kua phosphating cov neeg ua haujlwm siab; Raws li muaj pes tsawg leeg ntawm phosphating agents, muaj hlau raws li phosphating agents, zinc raws li phosphating agents, manganese raws li phosphating agents, zinc calcium raws li phosphating agents, zinc barium raws li phosphating agents, zinc manganese raws phosphating agents, thiab organic phosphating agents.
