Raws li kev tshaj lij oxidation thev naus laus zis, nws yog siv los kho cov dej khib nyiab, xws li cov ntaub ntawv tso tawm hauv cov tshuab hluav taws xob, thiab lwm yam. Raws li cov pa roj carbon dioxide thiab dej, txo cov pa oxygen xav tau (BiCy oxygarater, thiab ua kom nws tau kho tau yooj yim los ntawm kev kho mob raws li kev kho mob biological.

Ntim
Feem ntau, cov ntaub ntawv xws li ntau-ntom polyethylene (HDPE) thiab polypropylene (PP) tau xaiv. Cov plastics muaj cov tshuaj ruaj khov zoo, tsis yooj yim los ua kom muaj txiaj ntsig zoo rau hydrogen peroxide, thiab muaj qee yam hloov pauv, uas tuaj yeem tiv thaiv lub thawv tawg vim kev sib tsoo thiab lwm yam.
Chaw Cia Ib Cheeb Tsam
1. Kub: Hydrogen Peroxide yuav tsum tau muab cia rau hauv lub tsev rau khoom txias, tshuab ua kom txias, thiab qhov kub yuav tsum tsis pub dhau 30 degree. Kev kub dhau yuav nrawm peroxide, txo cov ntsiab lus muaj pa tawm los ntawm kev rhuav tshem, cov kev phom sij rau kev nyab xeeb.
2. Voj dej noo: Cov tshuaj vaum feem yuav tsum khaws cia 80%. Cov av noo dhau yuav ua rau hydrogen peroxide kom nqus noo noo hauv huab cua, thiab qee kis tau txhawb kev cuam tshuam kev cuam tshuam tshwm sim los ntawm kev tsis txaus siab.
3. Lub teeb: Hydrogen peroxide yog rhiab rau lub teeb, thiab lub teeb yuav ua rau nws poob, yog li nws yuav tsum tau muab cia rau hauv lub teeb pom kev zoo. Xim av iav lossis cov ntaub ntawv opaque (xws li cov yas dub yas) tuaj yeem siv txhawm rau ntxoov ntxoo lub thawv ntim khoom cia.

Cov FAQ
Q: Dab tsi yog hydrogen peroxide ua?
A: Hydrogen peroxide, lub npe zoo rau hydrogen peroxide a oxidant, tsis muaj tshuaj tua kab mob, pob txha caj dab, dawb huv thiab lwm daim teb; Cov kev xav tau feem ntau yog nyob ntawm 3% thiab 30% (pawg feem pua (thiab nws tuaj yeem sai sai thiab tsim cov pa oxygen ntawm qis dua; Ntawm lawv, cov siv ntau zaus rau kev kho mob tua kab yog 3% rau 5%, thiab qhov siab dua ntawm cov khoom siv oxidizing.
Q: Puas yog hydrogen peroxide tus neeg sawv cev dawb huv?
A: Hydrogen peroxide hydrogen peroxide (hydrogen peroxide (hydrogen peroxide (hydrogen peroxide (FLEYE tus neeg sawv cev rau cov plaub hau sib pab, tab sis kuj tuaj yeem tuaj yeem ua kom cov khaub ncaws plaub hau thiab tshem tawm cov hmoov av. Nws yog mob hnyav thiab tsis ua mob rau ib puag ncig. Thaum hydrogen peroxide yog nthuav tawm rau lub hnub, nws ib txwm decomposes rau hauv dej thiab oxygen, thiab yog biodegradable oxygen oxygen-buches neeg tus neeg sawv cev.
Q: Hydrogen Peroxide tua tuaj pwm?
A: Hydrogen Peroxide yog lwm txoj hauv kev zoo los tua pwm.
Q: Puas yog hydrogen peroxide flammable?
A: Tsis tau ua pa. Cov tshuaj uas tuaj yeem zes cov khoom siv hluav taws xob. Kev pheej hmoo ntawm hluav taws thiab tawg ntawm kev sib cuag nrog kub lossis hlau catalysts.
