Kev tsim cov tshuaj dawb huv

 

Kev npaj raw khoom

Nws pib nrog kev npaj ntawm raw cov ntaub ntawv, feem ntau slaked txiv qaub (calcium hydroxide) thiab chlorine gas. Slaked txiv qaub yog tsim los ntawm kev ntxiv dej rau quicklime (calcium oxide), ua rau cov hmoov zoo, qhuav. Cov roj chlorine feem ntau yog tsim los ntawm ntsev (sodium chloride) los ntawm cov txheej txheem electrolytic los yog tau los ntawm cov chaw tsim khoom. Cov ntaub ntawv no tau ua tib zoo tuav thiab khaws cia kom ntseeg tau tias lawv purity thiab ua haujlwm tau zoo hauv cov tshuaj tiv thaiv tom ntej.

 

Chlorination Reaction

Lub hauv paus ntawm cov txheej txheem ntau lawm suav nrog cov tshuaj tiv thaiv chlorination, qhov twg cov roj chlorine tau nkag mus rau cov slurry ntawm slaked txiv qaub. Cov tshuaj tiv thaiv no tshwm sim nyob rau hauv ib puag ncig tswj, feem ntau nyob rau hauv cov tshuaj tiv thaiv chamber los yog chlorinator. Cov roj chlorine reacts nrog calcium hydroxide los tsim calcium hypochlorite thiab calcium chloride raws li cov khoom lag luam. Cov tshuaj tiv thaiv thawj zaug tuaj yeem sawv cev raws li hauv qab no:

Ca(OH)2+2Cl2→Ca(OCl)2+2HCl\text{Ca(OH)}_2 + 2\text{Cl}_2 \rightarrow \text{Ca (OCl)}_2 + 2\text{HCl}Ca(OH)2+2Cl2 →Ca(OCl)2{10}}HCl

Cov tshuaj tiv thaiv no ua rau tsim cov calcium hypochlorite (bleaching hmoov) thiab hydrochloric acid. Cov tshuaj tiv thaiv kab mob, suav nrog qhov kub thiab txias thiab cov tshuaj chlorine concentration, ua tib zoo tswj kom ua kom zoo tshaj tawm thiab ua kom cov khoom zoo ntawm cov tshuaj dawb huv.

Kev sib cais thiab ziab

 

Tom qab cov tshuaj tiv thaiv chlorination, qhov sib xyaw ua ke muaj calcium hypochlorite hauv daim ntawv ntub dej, slurry. Qhov sib tov no ces raug rau kev sib cais kom tshem tawm cov dej ntau dhau thiab impurities. Feem ntau, cov slurry yog lim kom cais cov khoom calcium hypochlorite. Cov lim dej calcium hypochlorite tom qab ntawd qhuav siv ntau txoj hauv kev, xws li cov tshuab ziab khaub ncaws los yog cov tshuab ntxhua khaub ncaws, kom tshem tawm cov dej noo ntxiv. Cov txheej txheem kom qhuav hloov cov ntub dej slurry rau hauv cov hmoov zoo, qhuav hmoov haum rau ntim thiab xa tawm.

 

Ntim thiab Kev Tswj Xyuas Zoo

Cov kauj ruam kawg hauv kev tsim khoom suav nrog kev ntim khoom thiab kev tswj kom zoo. Cov hmoov qhuav calcium hypochlorite yog ua tib zoo ntim rau hauv cov thawv ntim dej kom tsis txhob degradation thaum khaws cia thiab thauj. Kev tswj xyuas zoo yog ua los xyuas kom cov khoom ua tau raws li cov qauv kev lag luam rau purity, chlorine cov ntsiab lus, thiab kev ua tau zoo. Cov kev ntsuam xyuas no yuav suav nrog kev tshuaj xyuas tshuaj thiab kev ntsuas kev ua haujlwm kom paub meej tias cov tshuaj dawb huv ua tau raws li qhov xav tau hauv nws cov kev siv ntau yam, xws li kev kho dej, kev huv huv, thiab kev siv hauv kev lag luam.

 

 

1. Dab tsi yog cov khoom siv raw khoom siv hauv nws?

Nws feem ntau yuav tsum tau slaked txiv qaub (calcium hydroxide) thiab chlorine gas. Slaked txiv qaub yog tsim los ntawm kev ntxiv dej rau quicklime (calcium oxide), ua rau cov hmoov zoo, qhuav. Cov roj chlorine, siv rau hauv cov tshuaj tiv thaiv chlorination, feem ntau yog tsim los ntawm cov ntsev (sodium chloride) los ntawm cov txheej txheem electrolytic los yog los ntawm cov khoom lag luam. Ob qho khoom siv raw yuav tsum tau tuav thiab khaws cia kom zoo kom ntseeg tau tias lawv cov purity thiab kev ua tau zoo hauv cov kauj ruam tom ntej.

 

2. Cov tshuaj chlorination ua haujlwm li cas hauv kev tsim cov tshuaj bleaching?

Cov tshuaj chlorination cuam tshuam nrog kev qhia cov roj chlorine rau cov slurry ntawm slaked txiv qaub (calcium hydroxide) nyob rau hauv ib puag ncig tswj. Cov roj chlorine reacts nrog calcium hydroxide los tsim calcium hypochlorite (bleaching hmoov) thiab hydrochloric acid raws li cov khoom lag luam. Cov tshuaj tiv thaiv tshuaj tuaj yeem sawv cev raws li:

Ca(OH)2+2Cl2→Ca(OCl)2+2HCl\text{Ca(OH)}_2 + 2\text{Cl}_2 \rightarrow \text{Ca (OCl)}_2 + 2\text{HCl}Ca(OH)2+2Cl2 →Ca(OCl)2{10}}HCl

Cov tshuaj tiv thaiv no yog ua tib zoo tswj los ntawm kev tswj qhov kub thiab txias thiab cov tshuaj chlorine kom ua kom zoo tshaj qhov tawm los thiab qhov zoo ntawm cov tshuaj bleaching ua.

 

3. Cov kauj ruam twg koom nrog hauv kev sib cais thiab ziab cov calcium hypochlorite tom qab cov tshuaj tiv thaiv?

Tom qab chlorination, qhov sib xyaw ua ke muaj calcium hypochlorite nyob rau hauv daim ntawv ntub dej, slurry. Qhov sib tov no dhau los ua cov txheej txheem sib cais kom tshem tawm cov dej ntau dhau thiab impurities, feem ntau los ntawm kev pom. Tom qab pom, cov calcium hypochlorite ntub dej yog qhuav siv txoj kev xws li cov tshuab ziab khaub ncaws los yog cov tshuab ntxhua khaub ncaws kom tshem tawm cov dej seem. Cov txheej txheem ziab no hloov cov slurry mus rau hauv cov hmoov zoo, qhuav, ua rau nws tsim nyog rau ntim thiab xa tawm.

 

4. Yuav ua li cas bleaching hmoov kawg ntim thiab vim li cas kev tswj kom zoo yog qhov tseem ceeb?

Cov kauj ruam kawg hauv cov txheej txheem tsim khoom suav nrog ntim cov hmoov calcium hypochlorite qhuav rau hauv cov thawv ntim dej kom tsis txhob degradation thaum khaws cia thiab thauj. Kev tswj xyuas kom zoo yog qhov tseem ceeb los xyuas kom meej cov hmoov bleaching ua tau raws li kev lag luam cov qauv rau purity, chlorine cov ntsiab lus, thiab kev ua tau zoo. Kev ntsuam xyuas tau ua thaum lub sij hawm tswj tau zoo suav nrog kev tshuaj xyuas tshuaj thiab kev ntsuas kev ua tau zoo los xyuas kom meej tias cov khoom lag luam ua tau zoo hauv nws cov ntawv thov, xws li kev kho dej, kev huv huv, thiab kev siv hauv kev lag luam.

 

5. Dab tsi yog qhov tseem ceeb ntawm cov tshuaj bleaching uas tsim los ntawm cov kab ke no?

Bleaching hmoov uas tsim los ntawm cov kab ke no yog dav siv rau ntau yam kev siv. Nws yog feem ntau ua hauj lwm hauv kev kho dej los tua kab mob thiab ntxuav cov dej haus, ua kom muaj kev nyab xeeb thiab kev nyiam huv. Hauv kev lag luam chaw, nws yog siv rau bleaching textiles thiab ntawv cov khoom, txhim khu lawv zoo thiab tsos. Tsis tas li ntawd, bleaching hmoov ua haujlwm hauv kev siv tshuaj ntxuav tes kom huv si thiab tswj cov kab mob microbial, ua rau nws muaj ntau yam thiab tseem ceeb tshuaj nyob rau hauv ntau yam lag luam.

 

6. Yuav ua li cas cov txheej txheem ntau lawm yog tswj kom ntseeg tau tias zoo bleaching hmoov?

Cov txheej txheem ntau lawm ntawm bleaching hmoov yog meticulously tswj kom zoo. Cov tsis tseem ceeb, xws li qhov kub thiab txias, chlorine concentration, thiab lub sij hawm tshuaj tiv thaiv, yog ua tib zoo saib xyuas kom zoo rau cov tshuaj tiv thaiv thiab cov khoom tawm los. Cov cuab yeej siv siab heev yog siv rau kev tswj xyuas meej thaum lub sij hawm chlorination, sib cais, thiab ziab theem. Kev soj ntsuam nruj nruj, suav nrog kev tshuaj xyuas tshuaj lom neeg thiab kev ntsuas kev ua tau zoo, yog ua los xyuas kom meej tias cov khoom kawg ua tau raws li cov qauv kev lag luam thiab ua tau zoo hauv nws cov kev siv ntau yam.
