2. Cov khoom lag luam zoo
3. Siv
Kev ua liaj ua teb: Phosphoric acid yog ib qho tseem ceeb raw khoom rau zus tau tej cov phosphate chiv (superphosphate, poov tshuaj dihydrogen phosphate, thiab lwm yam) raw cov ntaub ntawv.
Kev lag luam: Phosphoric acid yog ib qho tseem ceeb ntawm cov khoom siv raw, thiab nws cov haujlwm tseem ceeb yog raws li hauv qab no:
1. Kho cov hlau nto thiab tsim cov phosphate zaj duab xis insoluble ntawm cov hlau nto los tiv thaiv cov hlau los ntawm corrosion.
2. Sib xyaw nrog nitric acid ua cov tshuaj txhuam hniav los txhim kho qhov smoothness ntawm cov hlau nto.
3. Phosphateesters, raw cov ntaub ntawv rau kev tsim cov tshuaj detergents thiab tshuaj tua kab.
4. Cov khoom siv raw rau kev tsim cov phosphorus-muaj cov nplaim hluav taws
Khoom noj khoom haus: Phosphoric acid yog ib qho ntawm cov khoom noj ntxiv.Nws yog siv nyob rau hauv cov zaub mov raws li ib tug qaub neeg sawv cev thiab poov xab nutrient.Coca-Cola muaj phosphoric acid.Phosphate kuj yog ib qho khoom noj khoom haus tseem ceeb thiab tuaj yeem siv los ua zaub mov noj.
Cov hlau nto "phosphorification kho".Lub thiaj li hu ua phosphorus yog hais txog txoj kev tsim cov hlau ua haujlwm los ntawm cov kua qaub uas muaj dihydrogen-phosphate ntsev, thiab ib txoj hauv kev tsim cov txheej txheem ntawm cov phosphate membrane ruaj khov rau ntawm nws qhov chaw los tsim cov tshuaj tiv thaiv.Lub membrane hu ua phosphorum zaj duab xis.Lub hom phiaj tseem ceeb ntawm phosphorum zaj duab xis yog txhawm rau ua kom cov adhesion ntawm txheej zaj duab xis thiab txhim kho corrosion kuj ntawm txheej.Muaj ntau txoj hauv kev los phosphorify.Raws li qhov kub thiab txias thaum lub sij hawm phosphorusization, nws tuaj yeem muab faib ua phosphorus kub (90-98 ° C), nruab nrab kub phosphorus (60-75 ° C), tsis kub phosphate (35-55 ° C) thiab N chav sov phosphorus.
Kev siv thev naus laus zis ntawm phosphorum zaj duab xis yog dav siv hauv North America thiab European lub teb chaws.Kev siv tshuab passivation yog raws li cov yam ntxwv ntawm phosphate zaj duab xis nws tus kheej.phosphorum zaj duab xis yog nyias.Feem ntau, nws yog 1-4g / m2, uas tsis pub tshaj 10g / M2, nws qhov pore dawb yog qhov loj, thiab cov yeeb yaj kiab nws tus kheej muaj kev tiv thaiv corrosion.Qee tus txawm sai sai muaj xeb daj thaum lub sijhawm ziab.Tom qab phosphorusization, passivation thiab kaw kev kho mob tuaj yeem txuas ntxiv oxidized los ntawm cov hlau raug nyob rau hauv lub qhov hws ntawm phosphorurative zaj duab xis, los yog txheej passivation yog generated.Cov nyhuv oxidation ua rau cov phosphate stabilize nyob rau hauv cov huab cua.
Cov phosphate hloov dua siab tshiab zaj duab xis yog siv nyob rau hauv hlau, txhuas, zinc, cadmium, thiab nws cov alloys, uas yuav siv tau raws li qhov kawg refined txheej los yog nyob rau hauv nruab nrab txheej ntawm lwm cov txheej txheej.Nws lub luag haujlwm muaj cov hauv qab no.
Txawm hais tias kev txhim kho cov phosphorurative zaj duab xis yog nyias, vim hais tias nws yog ib tug non-metal non-conductive cais txheej, nws muaj peev xwm hloov lub zoo neeg xyuas pib ntawm lub nto ntawm cov hlau workpiece mus rau hauv ib tug adverse conductor, inhibit qhov tsim ntawm micro-hluav taws xob nyob rau saum npoo. cov hlau workpiece Corrosion ntawm txheej zaj duab xis.Table 1 teev cov teebmeem ntawm phosphate zaj duab xis ntawm hlau corrosion kuj.
Kev txhim kho cov adhesion zaj duab xis ntawm cov matrix thiab cov txheej txheem los yog lwm cov organic hniav txheej yog ib tug nruj zuag qhia tag nrho cov qauv uas muab ib tug zoo ua ke.Tsis muaj ciam teb pom tseeb thaum lub sijhawm.Cov khoom ntxeem tau ntawm cov yeeb yaj kiab phosphorurative ua rau tus neeg sawv cev kaw, txheej txheej, thiab lwm yam nkag mus rau hauv cov pores, thiab khi rau cov phosphoridized daim nyias nyias, txhawm rau txhim kho cov adhesion.
Muab cov phosphorus zaj duab xis kom huv si tuaj yeem loj hlob ntawm qhov chaw ntawm cov hlau ua haujlwm tsis muaj roj paug thiab xeb-dawb txheej.Yog li ntawd, hlau workpieces uas tau phosphorus tuaj yeem muab cov khoom huv si, zoo li qub, tsis muaj roj thiab xeb.
