Daim Ntawv Thov

Hauv kev lag luam electroplating:Sodium Hexahydroxostannate yog cov ntsev tseem ceeb rau kev plating alkaline tin. Sodium Hexahydroxostannate kuj tseem siv tau rau hauv cov txheej txheem electroplating xws li cyanide tooj liab-tin alloys thiab pyrophosphate. Nws yog siv rau cov khoom siv tsheb thiab phab ntsa sab hauv ntawm cov kav dej. Qhov kev tiv thaiv xeb ntawm cov tshuaj tsuag ntsev ntawm cov txheej txheej yog qhov zoo dua li ntawm cov txheej txheej tin ntshiab.

Hauv kev lag luam textile:Sodium hexahydroxostannate yog siv los ua cov tshuaj tiv thaiv hluav taws thiab cov tshuaj ntxiv rau qhov hnyav rau cov ntaub. Sodium hexahydroxostannate yog siv rau "kev ua kom tiav qhov hnyav" ntawm cov ntaub zoo nkauj thiab cov ntaub plaub, ua kom cov ntaub zoo nkauj thiab zoo nkauj (xws li cov phuam qhwv caj dab thiab cov ntaub plaub) yam tsis cuam tshuam rau qhov mos ntawm cov ntaub.

Hauv kev lag luam dyeing thiab luam ntawv:Sodium stannate trihydrate siv tau ua ib qho mordant los pab precipitate pigments.

Kev lag luam ceramic thiab enamel:Sodium stannate trihydrate kuj tseem siv tau rau hauv kev tsim cov khoom siv ceramics, iav, thiab lwm yam. Sodium hexahydroxostannate, ua cov kua nplaum rau cov khoom siv ceramic glazes thiab enamelware, tuaj yeem txo qhov melting point ntawm cov glazes, ua rau qhov chaw glaze zoo nkauj dua thiab du. Sodium stannate kuj tseem tuaj yeem txhim kho cov kua qaub thiab alkali tsis kam ntawm cov khoom siv ceramic lossis enamel thiab txuas ntxiv lawv lub neej kev pabcuam.

Cov yam ntxwv

1. Cov ntsiab lus ntawm cov khoom tsis zoo ((Fe), (Pb), (As)) qis dua li tus qauv hauv tebchaws, uas zam kev tsaus ntuj, pos huab, thiab kab txaij thaum lub sijhawm electroplating, thiab txo qhov kev tiv thaiv corrosion thiab weldability ntawm cov txheej.
2. Cov ntsiab lus ntawm Dawb alkali tuaj yeem tsawg dua 0.5% (lub teb chaws tus qauv ≤3.5), uas yog qhov zoo rau kev ruaj khov ntawm sodium stannate kua thiab zam kev muaj zog corrosiveness thaum siv.
3. Cov khoom siv raw ntawm peb lub tuam txhab yog los ntawm cov tin mines hauv Yunnan thiab Jiangxi xeev, sodium hexahydroxostannate muaj kev huv siab dua, muaj zog dua thiab siv cov khoom zoo dua.
4. Piv nrog rau cov khoom lag luam ntawm lwm lub Hoobkas, peb cov khoom sodium stannate trihydrate muaj kev ua haujlwm ruaj khov dua thiab tsis tshua muaj kev sib xyaw.
5. Piv nrog rau cov khoom Sodium stannate trihydrate los ntawm lwm lub Hoobkas hauv Suav teb thiab cov los ntawm txawv teb chaws, peb cov khoom sodium stannate muaj qhov ci ntsa iab dua. Qhov no ua rau cov khoom du, dawb dua thiab ci dua rau kev lag luam tsim khoom siv ceramic.
