Chaw tsim tshuaj paus Zoo Nqe Sodium Thiosulphate CAS: 7772-98-7

piav qhia luv luv:

Sodium Thiosulphate, feem ntau hu ua ntsev hiav txwv los yog ci dej qab zib, yog ib qho khoom siv raw khoom siv los ua tus neeg saib xyuas hauv kev yees duab, zaj duab xis, thiab luam ntawv. Siv los ua tus neeg ua kom txo qis hauv cov tawv nqaij. Hauv kev lag luam papermaking thiab textile, nws yog siv los tshem tawm cov tshuaj bleaching residual thiab ua ib qho hnyav rau cov phau ntawv dyeing. Siv ua tshuaj tua kab mob rau cyanide lom hauv tshuaj. Hauv kev kho dej, nws yog siv los ua tus neeg sawv cev dechlorination thiab bactericide rau cov dej haus thiab dej khib nyiab; Copper corrosion inhibitor rau circulating dej txias; Thiab deoxidizer rau boiler dej system. Nws kuj yog siv rau kev kho mob ntawm cyanide uas muaj cov dej khib nyiab, thiab lwm yam.

Hauv kev lag luam, dej qab zib tshauv thiab sulfur feem ntau yog siv los ua cov khoom siv los ua cov tshuaj sulfur dioxide uas ua los ntawm kev hlawv cov sulfur los tsim sodium sulfite. Tom qab ntawd, sulfur yog ntxiv rau cov tshuaj tiv thaiv boiling, thiab ces lim, decolorized, concentrated chemically condensed, thiab crystallized kom tau sodium thiosulfate pentahydrate. Lwm cov ntaub ntawv pov tseg uas muaj sodium sulfide, sodium sulfite, sulfur, thiab sodium hydroxide uas tsim tawm kuj tuaj yeem siv thiab ua tiav kom tau txais cov khoom.
