Cov yam ntxwv thiab cov lus qhia rau kev siv tshuaj tua kab mob Glutaraldehyde

Glutaraldehyde yog cov tshuaj tua kab mob zoo heev nrog rau dav -spectrum bactericidal zog, tsis muaj tshuaj lom, tsawg corrosiveness rau hlau, thiab tsis tshua muaj kev cuam tshuam los ntawm cov organic teeb meem. Nws kuj pom zoo stability.

Tam sim no, cov khoom lag luam muaj glutaraldehyde feem ntau suav nrog ob hom: 2% alkaline glutaraldehyde thiab 2% txhim kho acidic glutaraldehyde. Alkaline glutaraldehyde feem ntau yog siv los ua kom tsis muaj menyuam cov khoom siv kho mob. Sodium bicarbonate yuav tsum tau ntxiv ua ntej siv, thiab tom qab co thiab sawv rau ib teev, cov pH yuav tsum tau kuaj. Qhov zoo tshaj plaws bactericidal nyhuv yog tiav nyob rau hauv ib tug pH ntau ntawm 7.5-8.5. Alkaline glutaraldehyde muaj kev ruaj ntseg tsis zoo; nws cov monomers yooj yim polymerize ntawm pH 6, thiab polymerization accelerates nrog nce pH, muaj peev xwm ua rau nag lossis daus thiab cuam tshuam cov kab mob bactericidal.
2% txhim kho acidic glutaraldehyde muaj polyoxyethylene fatty cawv ether ua ib qho kev txhim kho, uas txhim kho cov kab mob bactericidal. Nws cov pH qis dua 5, thiab nws cov nyhuv tua ntawm cov kab mob spores tsis muaj zog dua li alkaline glutaraldehyde, tab sis nws muaj peev xwm ua kom tsis muaj kab mob thiab ruaj khov dua, tso cai rau kev siv txuas ntxiv rau 28 hnub.

I. Bactericidal Principple thiab Scope of Application

Glutaraldehyde belongs rau chav kawm aldehyde ntawm cov tshuaj tua kab mob. Nws feem ntau ua haujlwm los ntawm alkylating sulfhydryl, hydroxyl, carboxyl, thiab amino pawg hauv microbial proteins los ntawm nws pawg aldehyde, ua rau cov protein coagulation thiab yog li ua rau microbial tuag.
Cov tshuaj tua kab mob no yog tsim rau cov khoom siv kho mob uas tsis tuaj yeem tiv taus qhov kub thiab txias, nrog rau cov cuab yeej precision uas nkag siab rau ob qho tib si noo noo thiab cua sov.

II. Qhov zoo thiab ceev faj ntawm Glutaraldehyde Disinfectant

1) Qhov zoo:

1. Dav -spectrum bactericidal kev ua haujlwm, tua tau ntau yam kab mob.

2. Tshwj xeeb yog tsim nyog rau kev ua kom tsis muaj cua sov- cov khoom siv kho mob rhiab heev.

3. Tsis tshua muaj khaus thiab corrosiveness ntawm qhov pom zoo concentration, ua kom muaj kev nyab xeeb zoo.

4. Muaj cov nyhuv bactericidal ruaj khov txawm tias muaj cov organic teeb meem (xws li, ntawm 20% concentration).

2) Kev ceev faj:

1. Lub sij hawm ua kom tsis muaj menyuam yog qhov ntev, feem ntau yuav tsum tau ntau tshaj 10 teev.

2. Nws muaj qee yam tshuaj lom thiab khaus khaus thiab ua rau ua pa ua pa; kev tiv thaiv yuav tsum tau ua thaum ua haujlwm.

3. Cov cuab yeej ua kom tsis muaj glutaraldehyde yuav tsum tau muab yaug kom huv si nrog dej tsis huv ua ntej siv kom tshem tawm cov khoom seem.
