Sodium sulfide, tseem hu ua stinky alkali, stinky soda, thiab alkali sulfide, yog ib qho inorganic compound nrog cov tshuaj formula Na2S. Nws tshwm raws li cov xim tsis muaj xim crystalline hmoov. Nws yooj yim soluble hauv dej, insoluble hauv ether, thiab me ntsis soluble hauv ethanol. Nws tuaj yeem ua rau kub hnyiab thaum nws kov cov tawv nqaij thiab plaub hau, yog li sodium sulfide feem ntau hu ua alkali sulfide. Thaum raug huab cua, sodium sulfide tso tawm cov pa roj hydrogen sulfide uas tsw zoo li cov qe lwj. Muaj sodium sulfide muaj impurities thiab nws cov xim yog liab, xim av-liab, los yog av daj.
Khoom siv
Khoom siv
1. Nws yog siv nyob rau hauv kev lag luam dyeing los tsim sulfur dyes thiab yog raw khoom rau cyan sulfide thiab sulfide xiav. Hauv kev lag luam luam ntawv thiab dyeing, nws yog siv los ua dyeing auxiliary rau dissolve sulfur dyes. Hauv kev lag luam tanning, nws yog siv los hydrolyze nyoos hides thiab tawv kom tshem tawm cov plaub hau. Nws kuj yog siv los npaj sodium polysulfide kom ceev cov soaking ntawm qhuav hides nyob rau hauv dej los pab soften lawv. Hauv kev lag luam ntawv, nws yog siv los ua tus neeg sawv cev ua noj rau ntawv. Hauv kev lag luam textile, nws yog siv rau denitrification thiab nitrate txo ntawm cov txiv neej ua fibers, thiab raws li ib tug mordant rau dyeing paj rwb fabrics. Nws yog siv hauv kev lag luam kws tshuaj los tsim cov tshuaj tua kab mob xws li phenacetin. Tsis tas li ntawd, nws kuj yog siv los ua sodium thiosulfate, sodium hydrosulfide, sodium polysulfide, thiab lwm yam.
2. Ntxiv qhov tsim nyog ntawm sodium sulfide rau cov tshuaj alkaline etching rau txhuas thiab alloys tuaj yeem txhim kho qhov zoo ntawm etching nto. Nws kuj tseem siv tau los tshem tawm alkali-soluble hnyav hlau impurities xws li zinc hauv cov tshuaj alkaline etching.
3. Sodium sulfide kuj tuaj yeem siv los kho cov txheej txheem conductive hauv electroplating ncaj qha. Cov tshuaj tiv thaiv ntawm sodium sulfide thiab palladium generates colloidal palladium sulfide los tsim ib tug zoo conductive txheej ntawm cov hlau tsis muaj hlau.
4. Siv ua corrosion inhibitor. Nws tseem yog cov khoom siv raw rau sodium thiosulfate, sodium polysulfide, sulfur dyes, thiab lwm yam.
5. Siv nyob rau hauv kev tsim cov sulfur dyes, tawv depilatories, hlau smelting, photography, rayon denitration, thiab lwm yam.
Cov Lus Cim Khoom
Kev Tiv Thaiv Tus Kheej: Hnav cov cuab yeej tiv thaiv tsim nyog xws li tsom iav kev nyab xeeb, hnab looj tes thiab khaub ncaws thiab zam kev sib cuag ntawm daim tawv nqaij thiab qhov muag.
Ib puag ncig qhov cua: Xyuas kom qhov chaw ua haujlwm tau zoo ventilated kom tsis txhob muaj cov pa phem.
Tsis txhob sib xyaw nrog lwm yam tshuaj: Sodium sulfide tau txo cov khoom. Tsis txhob sib xyaw nrog cov kua qaub, oxidants thiab lwm yam khoom los tiv thaiv kev ua phem.
Kev khaws cia: Khaws rau hauv qhov chaw qhuav, qhov cua, thiab qhov chaw txias, kom deb ntawm qhov hluav taws kub thiab cov khoom siv hluav taws xob, thiab tsis txhob sib cuag nrog dej.
Hauv luv luv, cov txheej txheem kev nyab xeeb yuav tsum tau ua raws li nruj me ntsis thaum siv sodium sulfide kom ntseeg tau tias kev nyab xeeb ntawm tus kheej.
