Bleaching hmoov cog

1.Bleaching hmoov qhia

Bleach hmoov yog ib hom tshuaj tua kab mob thiab tshuaj tua kab mob, feem ntau muaj cov calcium hypochlorite (Ca(ClO)₂), qee zaum kuj muaj sodium hypochlorite (NaClO).

Khoom:

a. Oxidation: Bleach hmoov muaj zog oxidation zog thiab tuaj yeem rhuav tshem cov organic pigments, ua rau cov khoom ploj.

b. Alkaline: Calcium hypochlorite tsim cov tshuaj alkaline thaum yaj hauv dej.

c. Tsis ruaj khov: nws yooj yim rau decomposition nyob rau hauv lub teeb thiab kub, ua calcium chloride thiab oxygen.

d. Corrosivity: Nws muaj qee yam corrosive rau cov hlau thiab ntaub.

e. Toxicity: Hypochlorite muaj qee yam toxicity rau tib neeg lub cev thiab yuav tsum tau ua kom zoo.

Kev siv:

a.Disinfection: Siv los tua cov dej haus, dej hauv pas dej da dej, tsev kho mob, thiab ib puag ncig hauv tsev.

b.Bleach: Siv nyob rau hauv kev lag luam textile los bleach ntuj fibers xws li paj rwb thiab linen.

c.Cleaning tus neeg saib xyuas: siv los ntxuav thiab tshem tawm cov av, tshwj xeeb tshaj yog nyuaj rau tshem tawm stains.

d.Pulp bleaching: Siv nyob rau hauv daim ntawv kev lag luam los bleach pulp.

e. Kev kho dej khib nyiab: siv rau kev lag luam thiab hauv nroog kev kho dej khib nyiab kom tshem tawm cov organic teeb meem thiab chromaticity.

f.Agriculture: Siv rau hauv av tshuaj tua kab mob thiab tswj cov kab mob ntawm cov nroj tsuag.

g. Kev lag luam khoom noj khoom haus: siv los ua tshuaj tua kab mob hauv qee yam kev ua zaub mov.

h.Medical: Siv rau kev tua kab mob ntawm cov cuab yeej kho mob thiab khoom siv

2.Brief txheej txheem qhia txog tshuaj dawb paug hmoov cog

Cov txheej txheem Calcium Hypochlorite thiab Sodium Hypochlorite Txheej txheem yog ob txoj kev tsim khoom sib txawv rau bleaching hmoov.

Calcium Hypochlorite Txheej Txheem:

2 Ca(OH)₂ + 2Cl₂ → CaCl₂ + Ca(ClO)₂ + 2H₂O

Siv quicklime react nrog dej los tsim hydrated txiv qaub. Kev laus hydrated txiv qaub rau ib lub sij hawm los txhim kho nws purity thiab reactivity. Cov tshuaj chlorine (Cl₂) tau nkag mus rau hauv hydrated txiv qaub tshuaj pleev rau cov tshuaj chlorination los tsim calcium hypochlorite (Ca(ClO)₂) thiab calcium chloride. Cais cov khoom calcium hypochlorite generated los ntawm cov tshuaj tiv thaiv los ntawm cov kua los ntawm txoj kev xws li pom los yog centrifugation. Qhuav cov calcium hypochlorite sib cais kom txo cov dej noo thiab ua kom yooj yim cia thiab thauj mus los.

Sodium Hypochlorite Txheej Txheem:

Ca(OH)₂ + 2NaOH + 2Cl₂ → Ca(OCl)₂ + 2NaCl + 2H₂O

Ua ntej, npaj hydrated txiv qaub. Txhawm rau ntxiv cov kua txiv hmab txiv ntoo, cov dej qab zib caustic rau hauv # 1 reactor, tom qab ntawd tso cov roj chlorine, tswj cov tshuaj tiv thaiv kub. Tom qab cov tshuaj tiv thaiv tiav, cais cov khoom ntsev thiab kua, cov kua nkag mus rau hauv lub tank.

Txhawm rau ntxiv qee tus niam cov kua dej thiab cov txiv qaub hydrated rau hauv # 2 reactor, ua kom lub reactor kub, tso cov roj chlorine. Tom qab cov tshuaj tiv thaiv ua tiav, cais cov kua (cov kua tshuaj dawb) thiab cov khoom, cov av tom qab sib xyaw nrog cov kua uas los ntawm lub tank mus rau hauv # 3 reactor. Tswj lub reactor kub thiab tso cov roj chlorine. Tom qab cov tshuaj tiv thaiv tiav, cais cov khoom thiab cov kua, cov khoom yuav raug xa mus rau hauv lub tshuab ziab khaub ncaws, tom qab ntawd mus rau lub tshuab tawg thiab co mesh, cov khoom tsim nyog yuav raug ntim thiab cov khoom tsis tsim nyog rov qab mus rau txheej txheem granulating. Cov kua yuav nkag mus rau hauv lub pas dej niam.
