Sodium hypochlorite yog cov khoom siv tshuaj siv hauv ntau yam ua tshuaj tua kab mob. Cov tshuaj no tuaj yeem siv los tua txhua yam ntawm qhov chaw, khoom siv, kua, thiab lwm yam. Muaj ntau ntau yam ntawm cov khoom no. Feem ntau, piv txwv li, qib A sodium hypochlorite yog siv los ua tshuaj tua kab mob.

yog dab tsi

Cov khoom no yog muag raws li cov kua ntsuab-daj. Nws yog tau los ntawm electrolysis ntawm lub rooj ntsev. Qee zaum sodium hypochlorite kuj yog tsim los ntawm chlorinating aqueous tov ntawm sodium hydroxide. Cov tshuaj formula ntawm no compound yog raws li nram no - NaClO. Lub ntsiab qhov txawv ntawm qib A sodium hypochlorite yog nws cov tshuaj tua kab mob siab.

Ib txoj hauv kev, qhov sib xyaw no hu ua "javel" lossis "labarrac" dej. Hauv lub xeev dawb, sodium hypochlorite yog ib qho ncaj nceestseem tsis ruaj khov.

Scope of application

Sodium hypochlorite tuaj yeem tsim tau raws li GOST lossis TU. Thawj hom nyiaj yog siv rau kev tua kab mob hauv dej. Nws tuaj yeem yog:

• haus dej thiab kev siv dej hauv nruab nrab hauv kev siv hluav taws xob;

• kev lag luam thiab cov dej khib nyiab hauv tsev;
• dej hauv pas dej.

Sodium hypochlorite, ua raws li cov lus qhia tshwj xeeb thiab muaj qhov tsis zoo, kuj tseem siv tau, tau kawg, rau lub hom phiaj ntawm kev tua kab mob. Cov cuab yeej no, piv txwv li, feem ntau siv rau:

• tshuaj tua kab mob ntuj thiab dej pov tseg;
• kho dej hauv cov chaw nuv ntses;
• tshuaj tua kab mob hauv kev lag luam khoom noj.

Tsis tas li, qhov no sodium hypochlorite tuaj yeem siv rau kev tsim khoom ntawm ntau yam tshuaj bleaching. Qhov zoo ntawm cov tshuaj no thaum siv los ua tshuaj tua kab mob muaj xws li kev nyab xeeb ib puag ncig. Hauv ib puag ncig, sodium hypochlorite sai sai decomposes rau hauv dej, ntsev thiab oxygen.

Txoj Cai Ua Haujlwm

Ib qho ntawm qhov txawv ntawm qib A sodium hypochlorite yog tias nws tuaj yeem muaj kev cuam tshuam rau cov kab mob ntawm ntau hom. Ntawd yog, nws tuaj yeem raug xa mus rau pawg tshuaj tua kab mob thoob ntiaj teb.

Thaum yaj hauv dej, cov tshuaj no, zoo li cov tshuaj dawb huv, tsim cov kua qaub, uas muaj cov tshuaj tua kab mob. Cov qauv kev kawmtshuaj tua kab mob yog raws li nram no:

• NaClO + H_{20 / NaOH + HClO.}

Cov tshuaj tiv thaiv zoo li no yog qhov sib npaug. Kev tsim ntawm hypochlorous acid feem ntau nyob ntawm pH ntawm cov dej thiab nws qhov kub thiab txias.

Ua kom sodium hypochlorite hauv dej, piv txwv li, cov kab mob hauv qab no:

• kab mob enterococci;
• Yfungus Candida albicans;
• qee yam ntawm cov kab mob anaerobic.

Cov tshuaj no tua cov kab mob phem tsis yog tsuas yog ua tau zoo, tab sis kuj nrawm heev - hauv 15-30 vib nas this.

Sodium Hypochlorite Qib A Specifications

Raws li twb tau hais lawm, qhov sib xyaw no yog kua ntsuab. Cov yam ntxwv ntawm cov tshuaj tua kab mob no yog raws li nram no:

• huab hwm coj ntau ntawm chlorine - yam tsawg kawg 190 g / dm 3;
• lub teeb kis tau tus mob - yam tsawg kawg 20%;
• alkali concentration - 10-20 g/dm3 raws li NaOH;
• hlau concentration - tsis ntau tshaj 0.02 g/dm3.

Cov tshuaj chlorine nyob rau hauv cov ntsiab lus ntawm cov tshuaj no tuaj yeem ncav cuag li 95%.

Kev thauj mus los thiab khaws cia

Sodium hypochlorite tuaj yeem nchuav rau hauv ntau hom ntim. Feem ntau nws yog thauj nyob rau hauv rubberized steel railway tanks. Cov khoom no tuaj yeem ntim rau hauv cov thawv ua los ntawm fiberglass thiab polyethylene. kuj nyob rau hauvCov thoob thiab iav fwj tuaj yeem siv los ua cov ntim khoom. Los ntawm txoj kev, sodium hypochlorite raug thauj mus rau hauv cov thawv ua raws li cov qauv kev nyab xeeb.

Cov tshuaj no yuav tsum muab cia rau hauv cov chav uas tsis muaj cua sov. Nyob rau tib lub sijhawm, lub hnub ci yuav tsum tsis txhob tso cai kom ncav cuag cov sodium hypochlorite khaws cia. Hauv cov ntim loj, cov khoom no feem ntau yog khaws cia rau hauv cov roj hmab-coated steel ntim lossis hauv cov thawv coated nrog cov khoom tiv thaiv corrosion.

Hmoov tsis zoo, qib A sodium hypochlorite tsis tau lees paub. Cov tuam txhab lag luam muaj lub luag haujlwm rau dej tua kab mob yuav tsum tau txheeb xyuas qhov tsim nyog ntawm cov khoom no ua ntej siv. Qhov zoo ntawm qhov sib xyaw no yuav tsum tsis txhob qis dua qhov kev pom zoo los ntawm cov ntaub ntawv tswj hwm kev tshuaj tua kab mob ntawm cov khoom tshwj xeeb no.

Package Marking

Tsis muaj lub neej txee rau qib A sodium hypochlorite. Ua ntej siv, qhov sib xyaw no raug kuaj xyuas kom zoo los ntawm cov neeg siv khoom lag luam lawv tus kheej. Tab sis tau kawg, cov koom haum koom nrog hauv dej tua kab mob yuav tsum muaj cov ntaub ntawv qhia txog yam khoom uas lawv yuav.

Tau kawg, ntim nrog sodium hypochlorite, ib yam li lwm yam tshuaj lom neeg, tau sau npe, uas yuav tsum, ntawm lwm yam, muaj:

• tus neeg tsim khoom lub npe thiab kev tiv tauj;
• npe ntawm cov khoom tiag tiag nws tus kheej thiab nws lub npe;
• batch naj npawb thiab hnub timkev ua haujlwm.

Cov kev cai yooj yim ntawm kev siv

Kev nyab xeeb

Nws yog sodium hypochlorite, txawm tias tsis yog-flammable, tab sis caustic heev. Yog li ntawd, thaum ua hauj lwm nrog nws, cov kws tshwj xeeb yuav tsum tau tiv thaiv lawv ob txhais tes thiab ob lub qhov muag. Kev phom sij ntawm sodium hypochlorite hom A - II (chlorine). Cov tshuaj tua kab mob no tuaj yeem ua rau kub hnyiab hnyav yog tias nws nkag mus rau ntawm daim tawv nqaij. Yog tias qhov sib xyaw no nkag mus rau hauv lub qhov muag, tus neeg yuav txawm dig muag. Kev nqus pa ntawm cov vapors los ntawm cov khoom no tuaj yeem ua rau txhaws thiab khaus khaus.

Siv sodium hypochlorite rau cov neeg ua haujlwm tua kab mob yuav tsum hnav tag nrho siv cov cuab yeej tshwj xeeb:

• in BKF lossis B gas mask;
• hnab looj tes roj hmab;
• tsom iav;
• special costumes.

thaj chaw ntawm daim tawv nqaij tsis tuaj yeem raug rau qhov sib xyaw no yuav tsum tau yaug nrog ntau cov dej ntws tsawg kawg10 feeb. Yog hais tias splashes nkag mus rau hauv lub qhov muag ntawm tus neeg raug tsim txom, coj lawv mus rau kws kho mob. Ua ntej qhov no, tau kawg, yuav tsum tau ua kom huv si.

Ua raws li GOST 11086-76 qib A sodium hypochlorite, thaum qhuav, tuaj yeem ua rau muaj kev sib tsoo ntawm ntau hom organic. Yog li ntawd, nws tsis tuaj yeem khaws cov khoom sib xyaw no hauv tib chav, piv txwv li, nrog sawdust lossis rags.

Lwm hom

Ntxiv rau qib A sodium hypochlorite, NaClO tuaj yeem siv los ua tshuaj tua kab mob:

• brand B;
• B;
• G;
• E.

Cov kev daws teeb meem no tsis tshua muaj siab (nrog rau qib B sodium hypochlorite, tsim raws li cov lus qhia tshwj xeeb). NaClO qib E, ntxiv rau, tsis yog kua ntsuab, tab sis tsis muaj xim. Cov pob khoom uas muaj cov tshuaj hypochlorite B, thiab lwm yam, yuav tsum muaj cov ntawv sau "Tsis haum rau kev tua kab mob ntawm cov dej haus thiab hauv cov pas dej da dej."

Cov khoom ntawm lub npe no tuaj yeem siv tau rau cov ntaub bleaching. Tsis tas li, xws li sodium hypochlorite tuaj yeem siv los ua tus neeg sawv cev oxidizing hauv kev lag luam vitamin.
