Cov tshuaj muaj pes tsawg leeg ntawm xeb converter "Tsinkar"
Txheem
Zinkar yog dab tsi?
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm Tsinkar kuj muaj kev nyab xeeb rau tib neeg, tab sis tib lub sijhawm nws suav nrog cov khoom siv uas muaj txiaj ntsig zoo nrog cov chaw ntawm cov hlau puas. Nws yog raws li phosphoric acid purified siv cov tswv yim tshwj xeeb thiab diluted nrog dej, uas zinc thiab manganese tebchaw ntxiv.
Ib qho tseem ceeb ntawm cov xeb hloov Zinkar yog qhov muaj pes tsawg leeg ntawm cov tshuaj muaj xws li manganese thiab zinc nyob rau hauv lub xeev reactive, uas tsim ib tug tiv thaiv zaj duab xis ntawm tshwj xeeb lub zog ntawm cov hlau nto. Cov kws tshawb fawb tau ua pov thawj tias nws yog cov tshuaj nquag ntawm cov tshuaj, ua haujlwm ua khub, uas ua rau nws muaj peev xwm ua tiav kev ua haujlwm siab ntawm Tsinkar - txog 2-2,7 npaug siab dua li cov tshuaj monophosphate, uas loj dua ntawm kev ua lag luam thiab lawv yog. pheej yig dua, tab sis cov nyiaj khaws cia tsis raug cai.
Yuav ua li cas cov tshuaj uas tsim cov xeb converter Zinkar ua hauj lwm?
Lub luag haujlwm tseem ceeb ntawm zinc yog qhov cuam tshuam ncaj qha rau cov chaw ntawm electrochemical corrosion, tsim cov hlau tiv thaiv kev tiv thaiv. Nws lub ntsiab lus yog nyob rau hauv qhov tseeb hais tias nyob rau hauv lub zog ntawm huab cua masses tus tiv thaiv tawg, ua kom muaj kev ruaj ntseg ntawm cov hlau ntsiab nyob rau hauv nws.
Nrog kev pab los ntawm manganese, qhov chaw kho yog alloyed, uas yog, qhov zoo ntawm cov txheej txheem tiv thaiv tau zoo dua qub, uas kuj txawv Zincar los ntawm monophosphate tebchaw.
Orthophosphoric acid ua rau nws ua tau rau ob qho tib si zinc thiab manganese los qhia lawv tus kheej hauv txoj kev zoo tshaj plaws. Lub mechanism ntawm nws qhov kev txiav txim yog tsim los ntawm ib tug tiv thaiv txheej nyob rau hauv daim ntawv ntawm ib tug phosphate zaj duab xis, uas ho txhim kho adhesion, uas yog, adhesion ntawm cov hlau nto thiab cov paintings siv rau nws. Yog tias cov xim pleev xim thiab cov phosphate txheej raug puas lawm, qhov kev loj hlob ntawm cov chaw tiv thaiv corrosion nres nyob rau hauv cov ciam teb ntawm thaj chaw uas muaj kev ncaj ncees ntawm txheej tau ua txhaum. Nyob rau tib lub sijhawm, cov nyhuv ntawm phosphoric acid ntawm qhov ntsuas thiab tsis muaj dej oxides tsawg.
Tsis tas li ntawd, Zincar tov muaj tannin, nrog rau adsorption thiab passivating inhibitors. Thawj yog qhov tsim nyog rau kev hloov pauv ntawm cov hlau oxide rau hauv cov tebchaw uas tso cai rau cov kab mob xeb kom ua raws li qib molecular rau ib leeg thiab rau qhov tsis zoo ntawm cov hlau. Cov tom kawg yog tsim los ua kom qeeb cov txheej txheem corrosion ntau li ntau tau, thiab passivation tshwm sim nrog kev pab ntawm cov khoom uas muaj oxidation zog. Cov txheej tiv thaiv, suav nrog cov ntsiab lus passivating, qeeb tus nqi ntawm xeb ntawm cov hlau. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm adsorption inhibitors yog tsim cov yeeb yaj kiab ntxiv ntawm oxide txheej, uas txhim kho kev tiv thaiv corrosion.
Qhov tshwm sim ntawm kev sib cuam tshuam ntawm cov tshuaj lom neeg
Cov tshuaj muaj pes tsawg leeg ntawm Tsincar tso cai rau peb hais txog qhov no los tiv thaiv xeb ua ib qho ntawm cov tshuaj tiv thaiv zoo tshaj plaws ntawm kev ua haujlwm. Tam sim ntawd tom qab siv cov kev daws teeb meem rau cov txheej hlau cuam tshuam, cov ntsiab lus uas tsim cov khoom pib ua kom xeb, thaum cov oxide cov ntaub ntawv ntawm cov hlau hloov mus rau hauv phosphate sawv daws yuav. Thaum cov txheej txheem no, manganese reacts nrog zinc. Lawv pab txhawb rau kev tsim cov txheej txheem tiv thaiv txhim khu kev qha ntawm cov khoom nquag.
