Kev ceev faj thaum siv hydrogen peroxide

H2O2 - yog ib yam tshuaj muaj ntau yam thiab muaj txiaj ntsig zoo uas feem ntau siv hauv tsev rau ntau lub hom phiaj. Nws yog dav siv los ua tshuaj tua kab mob, tshuaj tua kab mob thiab tshuaj tua kab mob. Txawm li cas los xij, nws kuj yog ib qho tshuaj reactive heev uas tuaj yeem ua rau raug mob yog tias tsis siv kom raug. Hauv tsab xov xwm no, peb yuav tham txog qee qhov kev ceev faj uas yuav tsum tau ua thaum siv nws kom ntseeg tau tias koj muaj kev nyab xeeb.

1. Kev xav

Nws cov concentration txiav txim siab lub zog ntawm cov tshuaj. Cov tsev neeg qib hydrogen peroxide feem ntau muaj qhov concentration ntawm 3 feem pua. Qhov concentration no muaj kev nyab xeeb rau feem ntau tsev neeg lub hom phiaj, tab sis yuav tsum tsis txhob noj qhov ncauj. Kev lag luam qib hydrogen peroxide tuaj yeem nyob rau hauv ntau txog 30 feem pua. Qhov no concentration yog heev reactive thiab yuav tsum tsis txhob siv nyob rau hauv tsev.

2. Cov khoom siv tiv thaiv

Thaum ua haujlwm nrog hydrogen peroxide, nws yog ib qho tseem ceeb uas yuav tsum hnav cov khoom tiv thaiv xws li hnab looj tes thiab tsom iav kev nyab xeeb. Nws tuaj yeem ua rau tawv nqaij thiab qhov muag khaus, thiab kev raug mob ntev yuav ua rau muaj tshuaj lom. Thaum ntsib qhov muag, yaug tam sim nrog dej thiab nrhiav kev kho mob.

3. Cia

H2O2 yuav tsum muab cia rau hauv qhov chaw txias, qhuav kom deb ntawm tshav kub thiab lub teeb. Thaum tshav kub kub los yog lub teeb tuaj yeem ua rau cov tshuaj tawg, ua kom nws cov decomposition sai. Nws cov tshuaj decomposition tuaj yeem tsim cov pa roj carbon monoxide, uas tuaj yeem ua rau muaj kev sib tsoo thaum raug tshav kub lossis nplaim taws.

4. Sib tov

Hydrogen peroxide yuav tsum tsis txhob tov nrog lwm yam tshuaj tshwj tsis yog tias pom zoo los ntawm tus kws tshaj lij. Kev sib xyaw nrog lwm cov tshuaj yuav ua rau muaj kev kub ntxhov ua rau tawg lossis tso tawm cov pa phem. Tsis txhob sib tov nrog tshuaj dawb, ammonia lossis lwm yam tshuaj ntxuav tsev.

5. Pov tseg

H2O2 yuav tsum tau muab pov tseg kom zoo. Dilute hydrogen peroxide tuaj yeem nchuav rau hauv lub qhov dej, tab sis cov concentrated hydrogen peroxide yuav tsum tau coj mus rau qhov chaw pov tseg pov tseg. Tsis txhob muab pov rau hauv lub thoob khib nyiab li niaj zaus los yog nchuav rau hauv lub dab dej lossis chav dej.

Hauv kev xaus, H2O2 yog ib qho tshuaj siv tau zoo thiab muaj ntau yam uas feem ntau siv hauv tsev. Txawm li cas los xij, nws kuj yog ib qho tshuaj uas muaj peev xwm txaus ntshai uas yuav tsum tau saib xyuas. Ua raws li qhov tsim nyog ceev faj thaum siv kom ntseeg tau tias koj muaj kev nyab xeeb thiab kev nyab xeeb ntawm lwm tus. Nco ntsoov nyeem thiab ua raws li daim ntawv qhia cov lus qhia, hnav cov khoom tiv thaiv, thiab pov tseg kom raug.
