Hydrogen peroxide yog qhov sib xyaw ua ke nrog cov tshuaj hauv cov tshuaj H2O2. Cov tshuaj ntshiab hydrogen peroxide yog cov dej ua kua xiav xiav uas muaj peev xwm ua kom tsis haum nrog dej hauv ib qho kev sib faib. Nws yog ib qho muaj zog oxidant. Nws cov kua aqueous feem ntau hu ua hydrogen peroxide thiab yog cov xim ua kom tsis muaj xim thiab pob tshab. Nws cov kuab tshuaj tov yog tsim nyog rau kev kho mob qhov txhab kab mob, ib puag ncig kev ua kom huv thiab zaub mov ntxuav kab mob. Nyob rau hauv ib txwm muaj xwm txheej, nws yuav maj mam decompose rau hauv dej thiab oxygen, tab sis tus nqi decomposition yog qeeb heev. Txoj hauv kev ceev nrawm rau cov tshuaj tiv thaiv yog ntxiv cov catalyst (manganese dioxide, thiab lwm yam lossis irradiate nrog shortwave rays)
Hydrogen peroxide feem ntau yog tsim los ua cov kua tshuaj aqueous hydrogen peroxide rau kev siv.
Hydrogen peroxide yog siv rau kev kho mob, chaw ua tub rog thiab lub hom phiaj. Cov dej tua kab mob niaj hnub yog kev kho mob hydrogen peroxide. Kev kho mob hydrogen peroxide tuaj yeem tua cov kab mob plab hnyuv pathogenic, pyogenic cocci, thiab cov poov xab kab mob. Nws yog feem ntau siv rau kev tua kab mob rau saum npoo av. Cov tshuaj hydrogen peroxide muaj cov nyhuv oxidizing, tab sis kev saib xyuas ntawm kev kho mob hydrogen peroxide yog sib npaug los yog qis dua 3%. Thaum so rau ntawm lub qhov txhab mob, yuav muaj lub ntsej muag khaus, qhov chaw yuav oxidized kom dawb thiab cua npuas, tsuas yog ntxuav nws nrog dej, thiab nws yuav siv sijhawm li 3-5 feeb los rov kho dua daim tawv qub.
Hauv kev lag luam chemical, nws yog siv los ua cov ntaub ntawv nyoos rau kev tsim cov sodium perborate, sodium percarbonate, peroxyacetic acid, sodium chlorite, thiourea peroxide, thiab lwm yam, thiab cov tshuaj oxidizing rau tartaric acid thiab vitamins. Hauv kev lag luam kws tshuaj, nws yog siv los ua tshuaj tua kab mob, tshuaj tua kab mob thiab oxidant rau kev tsim tawm ntawm thiram tshuaj tua kab thiab 40l tshuaj tua kab mob. Hauv kev luam ntawv thiab dyeing kev lag luam, nws yog siv los ua tshuaj pleev rau cov xov paj kom txo cov xim tom qab dyeing nrog dyes. Siv los tshem cov hlau thiab lwm cov hlau hnyav hauv kev tsim cov hlau ntsev lossis lwm cov sib txuas. Nws kuj tseem siv hauv kev kho cov teeb meem electroplating kom tshem tawm cov khoom ua rau tsis haum thiab txhim kho qhov zoo ntawm cov plated qhov chaw. Nws kuj yog siv rau cov tshuaj ntxuav plaub tsiaj, ua cov ntuab nyoos, kaus ntxhw, sis plawv hniav, rog, thiab lwm yam.
Kev siv pej xeem: Los daws cov ntxhiab tsw ntawm lub lim dej hauv chav ua noj, yuav hydrogen peroxide, ntxiv cov dej thiab tshuaj ntxuav hauv lub tsev muag tshuaj, thiab muab nchuav rau hauv lub phwj kom txiav txim siab, ntxuav tsis tau thiab kom tsis muaj kab mob;
3% hydrogen peroxide (qib kev kho mob) tuaj yeem siv rau cov tshuaj tua kab mob rau lub qhov txhab;
