Cov tshuaj tua kab mob uas nquag siv tuaj yeem muab faib ua cuaj yam tseem ceeb raws li lawv cov khoom xyaw: chlorine- muaj cov tshuaj tua kab mob, tshuaj tua kab mob peroxide, tshuaj tua kab mob aldehyde, tshuaj tua kab mob cawv, iodine- muaj tshuaj tua kab mob, tshuaj tua kab mob phenolic, tshuaj tua kab mob ethylene biguanium oxide, tshuaj tua kab mob ntsev thiab tshuaj tua kab mob tshuaj tua kab mob.
chlorine- muaj cov tshuaj tua kab mob
Cov no yog cov tshuaj tua kab mob uas yaj hauv dej los tsim cov kua qaub hypochlorous, uas muaj cov tshuaj tua kab mob. Lawv cov tshuaj tiv thaiv kab mob muaj txiaj ntsig zoo feem ntau qhia tias muaj cov tshuaj chlorine. Hypochlorous acid muaj qhov hnyav molecular me me, yooj yim diffuses rau saum npoo ntawm cov kab mob, thiab nkag mus rau hauv cov cell membrane nkag mus rau cov kab mob ntawm tes, ua rau cov kab mob protein oxidation thiab ua rau cov kab mob tuag.
Cov tshuaj tua kab mob peroxide
Cov no muaj peev xwm oxidizing muaj zog, thiab ntau yam kab mob muaj kev nkag siab zoo rau lawv, muaj peev xwm tua tau tag nrho cov kab mob. Cov tshuaj tua kab mob no suav nrog hydrogen peroxide, peracetic acid, chlorine dioxide, thiab ozone. Lawv qhov zoo dua yog tias lawv tsis muaj tshuaj lom nyob hauv cov khoom tom qab tshuaj tua kab mob.
Aldehyde tshuaj tua kab mob
Cov no suav nrog formaldehyde thiab glutaraldehyde. Lub hauv paus ntsiab lus ntawm kev tua kab mob ntawm hom no yog tias cov tshuaj reactive alkylating ua rau cov amino, carboxyl, hydroxyl, thiab sulfhydryl pawg hauv cov kab mob microbial, yog li rhuav tshem cov protein molecules thiab ua rau microbial tuag. Cawv-cov tshuaj tua kab mob raws li dej cawv
Feem ntau siv yog ethanol thiab isopropanol. Lawv coagulate proteins, ua rau tuag ntawm microorganisms. Muab faib ua qhov nruab nrab -cov tshuaj tua kab mob ua tau zoo, lawv tua cov kab mob vegetative thiab rhuav tshem cov kab mob lipophilic feem ntau, xws li tus kab mob herpes simplex, kab mob siab B, thiab kab mob tib neeg kev tiv thaiv kab mob.
Iodine- muaj cov tshuaj tua kab mob
Xws li tincture ntawm iodine thiab povidone-iodine, lawv tua cov kab mob vegetative, fungi, thiab qee yam kab mob. Lawv tuaj yeem siv rau kev tua kab mob ntawm daim tawv nqaij thiab mucous daim nyias nyias thiab feem ntau siv hauv tsev kho mob rau kev phais tes tua kab mob.
Phenolic tshuaj tua kab mob
Xws li phenol, cresol, halogenated phenols, thiab phenol derivatives. Feem ntau siv phenol xab npum, tseem hu ua Lysol, muaj methylphenol ua nws cov khoom tseem ceeb. Halogenated phenols tuaj yeem txhim kho cov kab mob bactericidal ntawm phenol. Piv txwv li, trichlorohydroxydiphenyl ether yog dav siv los ua cov tshuaj tua kab mob hauv chaw kho mob thiab kev txuag.
Ethylene oxide
Kuj tseem hu ua ethylene oxide, nws yog cov tshuaj tua kab mob zoo heev uas tuaj yeem tua tag nrho cov kab mob. Vim nws muaj zog nkag mus rau hauv lub zog, nws feem ntau yog siv los tua kab mob los yog kom tsis muaj menyuam ntawm tawv, yas, khoom siv kho mob, thiab ntim khoom kho mob. Nws tsis ua puas feem ntau cov khoom thiab tuaj yeem siv rau kev tua kab mob ntawm cov cuab yeej precision thiab cov khoom muaj nqis. Nws tsis muaj kev cuam tshuam rau cov xim ntawv thiab feem ntau yog siv rau kev tua kab mob ntawm cov phau ntawv thiab cov ntaub ntawv sau.
Biguanide thiab Quaternary Ammonium ntsev tshuaj tua kab mob
Tsis tas li ntawd, muaj biguanide thiab quaternary ammonium ntsev tshuaj tua kab mob. Cov no yog cationic surfactants nrog bactericidal thiab detergency zog. Hauv tsev kho mob, lawv feem ntau yog siv los ntxuav thiab tshuaj tua kab mob uas tsis yog - cov khoom tseem ceeb thiab tseem tuaj yeem siv los ntxuav tes. Dissolving lawv hauv ethanol txhim kho lawv cov kab mob bactericidal, ua rau lawv haum raws li cov tshuaj tua kab mob ntawm daim tawv nqaij. Vim tias cov tebchaw no tuaj yeem hloov pauv cov permeability ntawm cov kab mob ntawm tes, lawv feem ntau ua ke nrog lwm cov tshuaj tua kab mob txhawm rau txhim kho lawv cov kab mob bactericidal thiab nrawm.
