Chaw tsim tshuaj paus zoo Sodium thioolulphate CAS: 7772-98-7

Cov lus piav qhia luv luv:

Sodium thiosulphate, feem ntau paub txog hiav txwv ntsev los yog ci dej qab zib, yog ib qho siv cov khoom siv tshuaj lom neeg siv ua duab thaij duab, zaj duab xis, thiab luam ntawv. Siv los ua tus neeg sawv cev txo cov tawv nqaij ua. Nyob rau hauv lub papermaking thiab textile Industries, nws yog siv los tshem tawm cov chaw ua tshuaj dawb thiab raws li cov kuab tshuaj rau cov phau ntawv doweing. Siv los ua cov tshuaj tiv thaiv rau kev lom neeg cyanide muaj tshuaj. Hauv kev kho dej, nws yog siv los ua cov kab ke zoo nkauj thiab cov kab ntsig rau cov dej haus thiab dej kom qhuav; Tooj liab corrosion inhibitor rau comgrulating cua txias dej; Thiab deoxidizer rau cov dej dej rhaub dej. Nws tseem siv rau kev kho ntawm cyanide uas muaj cov dej khib nyiab, thiab lwm yam.

Hauv kev lag luam, dej tshauv Tom qab ntawd, leej fajrfur tau ntxiv rau boiling cov tshuaj tiv thaiv, thiab tom qab ntawd lim, concolorized siv cov hws, thiab crystallized kom tau txais sodium thiosulfate pentahydrate. Lwm cov ntaub ntawv pov tseg muaj sodium sulfide, sodium sulfite, leej faj, thiab sodium hydroxide tsim kuj tseem tuaj yeem siv tau thiab ua tiav kom raug rau cov khoom.
