1. Kev txhais ntawmdisinfection thiab sterilization
Disinfection: Nws yog kev tshem tawm cov kab mob, kab mob, thiab kab mob uas ua rau tib neeg lub cev tsis zoo.
Sterilization: Tua tag nrho cov kab mob.Txawm hais tias cov kab mob microorganisms muaj teeb meem lossis muaj txiaj ntsig zoo rau tib neeg lub cev.
2. Cov txheej txheem ntawm kev tua kab mob thiab ua kom tsis muaj menyuam
(1) Txoj kev siv tshuaj: tshuaj tua kab mob thiab ua kom tsis muaj menyuam yog ua los ntawm kev so, txau thiab fumigating nrog cov tshuaj tsis muaj menyuam.Cov tshuaj no yog corrosive mus rau ib tug tej yam degree, yog li ntawd lub nto yuav sterilized yuav tsum muaj zoo corrosion kuj.
sterile tshuaj:
ib.Fumigation nrog ethylene oxide roj.25 ° C, 30% txheeb ze av noo, 8 ~ 16 teev.Muaj qee qhov kev toxicity.
b.Peroxyacetic acid.Concentration 2% tshuaj tsuag.25 ° C, 20 feeb.Nws yog corrosive.
c.Acrylic acid gas fumigation.25 ° C, txheeb ze humidity 80%.Cov tshuaj yog 7 g / m3.Muaj qee qhov kev toxicity.
d.Formaldehyde gas fumigation.25 ° C, txheeb ze humidity 80%.Cov tshuaj yog 35 ml / m3.Muaj qee qhov kev toxicity.
e.Formalin gas fumigation.25 ° C, txheeb ze humidity 10%.10 feeb.Nws yog khaus.
(2) Ultraviolet irradiation: Ultraviolet feem ntau muaj lub wavelength ntawm 1360 ~ 3900, thiab ultraviolet nrog lub wavelength ntawm 2537 muaj peev xwm ua kom tsis muaj zog tshaj plaws.Lub peev xwm ua kom tsis muaj menyuam ntawm UV teeb yuav txo qis nrog lub sijhawm nce.Feem ntau, cov zis hluav taws xob ntawm 100 teev ntawm qhov hluav taws xob yog qhov ntsuas hluav taws xob tso tawm, thiab lub sijhawm hluav taws xob thaum lub teeb hluav taws xob UV teeb rau 70% ntawm cov ntsuas hluav taws xob txhais tau tias yog lub neej nruab nrab ntawm UV teeb.Yog tias UV teeb dhau qhov nruab nrab lub neej tab sis qhov kev cia siab ua kom tsis muaj menyuam tsis tuaj yeem ua tiav, UV teeb yuav tsum tau hloov.
Cov nyhuv sterilization ntawm covUV teebkuj tseem txawv nrog ntau hom, thiab cov koob tshuaj irradiation rau tua cov pwm yog sib npaug rau 40-50 npaug ntawm irradiation koob tshuaj tua kab mob.Cov nyhuv sterilization ntawm UV teeb kuj muaj feem xyuam nrog cov av noo ntawm huab cua.Tus txheeb ze humidity ntawm 60% yog tus nqi tsim.Thaum tus txheeb ze humidity tshaj 60%, qhov raug yuav tsum tau nce.
Ultraviolet teeb irradiation yuav tsum tau nqa tawm nyob rau hauv lub xeev unmanned vim hais tias muaj tej yam kev puas tsuaj rau tib neeg lub cev.Lub teeb ultraviolet muaj cov txiaj ntsig zoo ntawm kev ua kom tsis muaj menyuam thiab irradiating ntawm qhov chaw, tab sis nws muaj qhov cuam tshuam me ntsis rau cov cua ntws.
(3) Qhov kub thiab txias siab ua kom tsis muaj menyuam: Qhov kub thiab txias kub kom tsis muaj menyuam yog feem ntau 160 ~ 200 ℃.Nws yuav siv sij hawm 2 teev kom ua tiav lub hom phiaj ntawm kev ua kom tsis muaj menyuam;Thaum qhov kub thiab txias yog 121 ℃, lub sijhawm ua kom tsis muaj menyuam tsuas yog 15-20 feeb.
(4) Muaj lwm txoj kev ua kom tsis muaj menyuam xws li lysozyme, nanometer, thiab hluav taws xob.Tab sis txoj kev siv ntau tshaj plaws yog txoj kev lim dej kom tsis muaj menyuam.Covlimlim tawm cov kab mob thiab cov kab mob uas txuas nrog rau cov plua plav thaum lim cov plua plav.
