Sodium hypochlorite (xws li: tshuaj dawb), tshuaj formula yog NaClO, yog cov tshuaj tsis muaj tshuaj chlorine uas muaj tshuaj tua kab mob. Cov khoom siv sodium hypochlorite yog cov hmoov dawb, thiab cov khoom lag luam dav dav yog cov kua tsis muaj xim lossis lub teeb daj nrog cov ntxhiab tsw. Nws yog yooj yim soluble nyob rau hauv dej los tsim caustic soda thiab hypochlorous acid. [1]

Sodium hypochlorite yog siv los ua cov tshuaj bleaching nyob rau hauv cov ntaub so ntswg, textiles thiab tshuaj fibers, thiab raws li ib tug dej purifier, bactericidal, thiab tshuaj tua kab mob nyob rau hauv dej kho.

Sodium hypochlorite muaj nuj nqi:

1. Rau bleaching ntawm pulp, textiles (xws li ntaub, phuam, undershirts, thiab lwm yam), tshuaj fibers thiab starch;

2. Kev lag luam xab npum yog siv los ua cov tshuaj dawb rau cov roj thiab cov rog;

3. Kev lag luam tshuaj yog siv los tsim hydrazine hydrate, monochloramine thiab dichloramine;

4. Chlorinating tus neeg sawv cev rau kev tsim cov cobalt thiab npib tsib xee;

5. Siv los ua tus neeg saib xyuas dej, tshuaj tua kab mob thiab tshuaj tua kab mob hauv kev kho dej;

6. Kev lag luam dyeing yog siv los tsim sulfide sapphire xiav;

7. Kev lag luam organic yog siv hauv kev tsim cov chloropicrin, ua cov tshuaj ntxuav tes acetylene los ntawm calcium carbide hydration;

8. Kev ua liaj ua teb thiab tsiaj txhu yog siv los ua tshuaj tua kab mob thiab tshuaj tua kab mob rau zaub, txiv hmab txiv ntoo, feedlots thiab tsiaj tsev;

9. Khoom noj khoom haus qib sodium hypochlorite yog siv rau kev tua kab mob ntawm cov dej haus, txiv hmab txiv ntoo thiab zaub, thiab kev ua kom tsis muaj menyuam thiab tshuaj tua kab mob ntawm cov khoom tsim khoom noj thiab cov khoom siv, tab sis nws tsis tuaj yeem siv rau hauv cov txheej txheem tsim khoom noj uas siv cov noob hnav ua raw khoom.

PROCESS:

High purity ntsev yaj nyob rau hauv lub nroog kais dej kom saturation brine dej thiab ces tso cov dej brine rau electrolysis cell los tsim chlorine gas thiab caustic soda, thiab cov chlorine gas thiab caustic soda yuav tsum tau kho ntxiv thiab reacts los tsim sodium hypochlorite uas yuav tsum tau. sib txawv concentration, 5%, 6%, 8%, 19%, 12%.
