Nrog rau qhov nrov ntawm kev tua kab mob thiab ua kom tsis muaj menyuam, ntau yam teeb meem ntawm daim ntawv -cov hnab ntim yas tau pib tshwm. Ntawm lawv, qhov teeb meem tshwm sim yog qhov teeb meem huab cua ntawm daim ntawv - cov hnab ntim yas. Cov pa xau ntawm daim ntawv- ntim yas txhais tau hais tias kev ua haujlwm ntawm kev cais cov kab mob tsis zoo, thiab nws kuj txhais tau hais tias yog li ntawd, yuav ua li cas thiaj paub tias cov ntawv tsis muaj kab mob - cov hnab ntim cov hnab yas yog qhov tseem ceeb heev. Nyob rau tib lub sijhawm, nyob rau hauv cov txheej txheem ntawm kev siv tshuaj, peb feem ntau pom tias cov khoom uas tau ua kom tsis muaj menyuam yog shrunk thaum lawv khaws cia, uas ua rau lub tswv yim tias lawv cov airtightness tau raug puas tsuaj. Hom lub hnab ntim no puas tuaj yeem tsis tuaj yeem ua pa? Puas yog nws tsis tuaj yeem siv nws thaum koj hnia nws?
Daim ntawv- ntim yas siv cov ntawv ua pa, yog li nws yog qhov ua pa tiag tiag, tab sis nws tuaj yeem thaiv cov kab mob. Qhov no yog raws li qhov kev xav ntawm Tshooj 2 ntawm Shiqiao Moderator. Tam sim no, peb cov thev naus laus zis tuaj yeem ua tau raws li qhov yuav tsum tau ua, tab sis qhov cua tshuab no txawv ntawm peb qhov kev nkag siab ib txwm muaj. Nws txawv me ntsis rau cov laj thawj hauv qab no:
1. Lub aperture ntawm daim ntawv breathable siv nyob rau hauv daim ntawv - cov hnab yas feem ntau yog 0.4um, uas tuaj yeem ua pa, tab sis nws tsis tuaj yeem hnov ntawm tes.
2. Qhov xwm txheej xav tau los ntawm tus neeg saib xyuas ntawm Shiqiao: Vim lub taub me me ntawm cov tawv taub hau koob, txoj kab uas hla ntawm daim tawv taub hau yog kwv yees li ntawm 200-600um, tab sis nws yog qhov loj dua li qhov pore loj ntawm daim ntawv breathable thiab tseem loj dua li qhov loj ntawm cov kab mob microorganisms, thiab nws cov microorganisms ua haujlwm zoo heev.
3. Txawm li cas los xij, cov cua ntws hauv qhov aperture ntawm 200-600um. Peb tuaj yeem hnov nws los ntawm kev rub nws nrog peb txhais tes, tab sis peb tseem tsis tuaj yeem hnov qhov pom tseeb ntawm huab cua to.
4. Yog li ntawd, tam sim no tsis muaj ib txoj hauv kev yooj yim rau kev txheeb xyuas qhov kev tshuaj xyuas tom qab lub hnab ntim khoom puas los ntawm tus pinhole.
5. Yog tias kev tshuaj xyuas yog siv rau kev soj ntsuam, qee qhov kev siv tau siv tau, xws li cov cuab yeej siv tau siv lub zog xau tester, txoj kev sim tuaj yeem siv cov dye kua nkag mus soj ntsuam txoj kev, thiab lwm yam. Cov tom kawg yog siv los ntawm immersing lub punctured pob qauv hauv cov tshuaj zas xim thiab soj ntsuam tias lub pinhole yuav pom ib qho chaw tsaus. Txawm li cas los xij, cov txheej txheem no tsis haum rau kev kuaj mob.
