Ntxuav thiab tshuaj tua kab mob ntawm cov cuab yeej thaum lub sij hawm kab lis kev cai ntawm tes

1. Kev ntxuav iav

Disinfection ntawm iav tshiab

1. Txhuam nrog dej kais dej kom tshem tawm cov plua plav.

2. Qhuav thiab soaking nyob rau hauv hydrochloric acid: qhuav nyob rau hauv qhov cub, thiab ces muab tso rau hauv 5% dilute hydrochloric acid rau 12 teev kom tshem tawm cov av, lead, arsenic thiab lwm yam khoom.

3. Txhuam thiab ziab: ntxuav nrog cov kais dej tam sim ntawd tom qab 12 teev, tom qab ntawd txhuam nrog xab npum, ntxuav nrog dej kais dej thiab tom qab ntawd qhuav hauv qhov cub.

4. Pickling thiab tu: soak hauv tshuaj ntxuav (120g ntawm poov tshuaj dichromate: 200ml ntawm concentrated sulfuric acid: 1000ml ntawm distilled dej) rau 12 teev, ces tshem tawm cov tais diav los ntawm lub acid tank thiab ntxuav lawv nrog kais dej rau 15 zaug, thiab Thaum kawg ntxuav lawv nrog dej distilled rau 3-5 zaug thiab muab ob npaug rau dej distilled rau 3 zaug.

5. Kev ziab thiab ntim: Tom qab ntxuav, qhuav ua ntej, thiab tom qab ntawd ntim nrog kraft ntawv (glossy paper).

6. Cov tshuaj tua kab mob siab: muab cov khoom ntim ntim rau hauv lub tshuab ua kom siab thiab npog nws.Qhib qhov hloov thiab kev nyab xeeb valve.Thaum cov pa nce hauv txoj kab ncaj nraim, kaw qhov kev nyab xeeb valve.Thaum tus taw tes taw tes rau 15 phaus, tuav nws li 20-30 feeb.

7. Qhuav tom qab siv tshuaj tua kab mob siab

Disinfection ntawm cov iav qub

1. Txhuam thiab ziab: siv cov iav tuaj yeem tsau ncaj qha rau hauv cov tshuaj lysol lossis tshuaj ntxuav tes.Cov iav ntim hauv cov tshuaj lysol (detergent) yuav tsum tau ntxuav nrog dej huv thiab ces qhuav.

2. Pickling thiab tu: tsau rau hauv cov tshuaj ntxuav tu (acid tov) tom qab ziab, tshem tawm cov tais diav los ntawm cov kua qaub tom qab 12 teev, thiab tam sim ntawd ntxuav lawv nrog dej kais dej (kom tiv thaiv cov protein los ntawm lo rau lub khob tom qab ziab), thiab tom qab ntawd ntxuav lawv nrog dej distilled rau 3 zaug.

3. Kev ziab thiab ntim khoom: Tom qab ziab, tshem tawm cov tais diav huv huv thiab siv cov ntawv kraft (glossy paper) thiab lwm cov ntim khoom kom yooj yim ntxuav thiab khaws cia thiab tiv thaiv plua plav thiab rov ua paug.

4. High-pressure disinfection: muab cov khoom ntim ntim rau hauv lub tshuab hluav taws xob siab, kaw lub hau, qhib qhov hloov thiab kev nyab xeeb valve, thiab lub valve muaj kev nyab xeeb emissions thaum kub nce.Thaum lub zog nce hauv txoj kab ncaj nraim rau 3-5 feeb, kaw qhov kev nyab xeeb valve, thiab qhov ntsuas ntsuas ntsuas yuav nce.Thaum tus taw tes taw qhia rau 15 phaus, kho qhov hluav taws xob hloov rau 20-30 feeb.( Maj mam npog lub hau roj hmab ua ntej kom tsis muaj menyuam ntawm lub khob kab lis kev cai lub raj mis)

5. Kev ziab kom qhuav: Vim tias cov tais diav yuav ntub los ntawm chav dej tom qab siv tshuaj tua kab mob siab, lawv yuav tsum tau muab tso rau hauv qhov cub kom qhuav kom qhuav.

Cov cuab yeej siv hlau tu

Cov khoom siv hlau tsis tuaj yeem tsau rau hauv cov kua qaub.Thaum ntxuav, lawv tuaj yeem ntxuav nrog xab npum ua ntej, tom qab ntawd ntxuav nrog dej kais dej, tom qab ntawd so nrog 75% cawv, tom qab ntawd ntxuav nrog dej, tom qab ntawd qhuav nrog dej distilled lossis ziab hauv huab cua.Muab tso rau hauv ib lub thawv aluminium, ntim rau hauv lub tshuab hluav taws xob siab, ua kom tsis muaj menyuam nrog 15 phaus ntawm kev kub siab (30 feeb), thiab tom qab ntawd qhuav rau qhov muag.

Roj hmab thiab yas

Txoj kev kho mob niaj hnub rau cov roj hmab thiab cov khoom lag luam yog ntxuav lawv nrog xab npum, ntxuav lawv nrog dej kais dej thiab dej distilled raws li, thiab tom qab ntawd qhuav hauv qhov cub, thiab tom qab ntawd ua raws li cov txheej txheem kho mob raws li qhov sib txawv:

1. Lub koob lim cap tsis tuaj yeem tsau hauv cov kua qaub.Soak hauv NaOH rau 6-12 teev, lossis boil rau 20 feeb.Ua ntej ntim, nruab ob daim ntawv lim zaj duab xis.Ua tib zoo saib rau sab du (concave side up) thaum txhim kho cov yeeb yaj kiab lim.Tom qab ntawd tshem tawm cov ntsia hlau me ntsis, muab tso rau hauv ib lub thawv aluminium, tshuaj tua kab mob hauv lub tshuab hluav taws xob siab rau 15 phaus thiab 30 feeb, thiab tom qab ntawd qhuav nws rau standby.Nco ntsoov tias cov ntsia hlau yuav tsum tau nruj tam sim ntawd thaum nws raug tshem tawm ntawm lub rooj ultra-huv.

2. Tom qab ziab cov roj hmab stopper, boil nws nrog 2% sodium hydroxide tov rau 30 feeb (cov roj hmab stopper yuav tsum tau kho nrog boiling dej rau 30 feeb), ntxuav nws nrog kais dej thiab qhuav nws.Tom qab ntawd soak hauv hydrochloric acid tov rau 30 feeb, ces ntxuav nrog kais dej, dej distilled thiab peb-steam dej, thiab qhuav.Thaum kawg, muab tso rau hauv lub thawv aluminium rau kev siv tshuaj tua kab mob siab thiab ziab kom qhuav.

3. Tom qab ziab, lub hau roj hmab thiab cov yeeb nkab centrifugal tsuas tuaj yeem tsau hauv 2% sodium hydroxide tov rau 6-12 teev (nco ntsoov tsis txhob ntev dhau), ntxuav thiab qhuav nrog dej kais.Tom qab ntawd soak hauv hydrochloric acid tov rau 30 feeb, ces ntxuav nrog kais dej, dej distilled thiab peb-steam dej, thiab qhuav.Thaum kawg, muab tso rau hauv lub thawv aluminium rau kev siv tshuaj tua kab mob siab thiab ziab kom qhuav.

4. Lub taub hau roj hmab tuaj yeem tsau hauv 75% cawv rau 5 feeb, thiab tom qab ntawd siv tom qab ultraviolet irradiation.

5. Yas kab lis kev cai lub raj mis, kab lis kev cai phaj, khov cia tube.

6. Lwm txoj kev siv tshuaj tua kab mob: qee cov khoom tsis tuaj yeem ua kom tsis muaj menyuam qhuav los yog ua kom tsis muaj menyuam hauv chav, thiab tuaj yeem ua kom tsis muaj menyuam los ntawm soaking hauv 70% cawv.Qhib lub hau ntawm cov yas kab lis kev cai tais diav, muab tso rau ntawm lub rooj noj mov ultra-huv, thiab ncaj qha nthuav tawm nws mus rau ultraviolet lub teeb rau tshuaj tua kab mob.Ethylene oxide kuj tuaj yeem siv los tua cov khoom yas.Nws yuav siv sij hawm 2-3 lub lis piam los ntxuav cov ethylene oxide residual tom qab tshuaj tua kab mob.Cov txiaj ntsig zoo tshaj plaws yog tshuaj tua kab mob cov khoom yas nrog 20000-100000rad r rays.Txhawm rau tiv thaiv kev tsis sib haum xeeb ntawm cov khoom siv tshuaj tua kab mob thiab tsis siv tshuaj ntxuav, cov ntawv ntim ntawv tuaj yeem raug cim nrog tus cwj mem ze.Tus txheej txheem yog siv tus cwj mem dej los yog ib qho kev sau ntawv los rau hauv tus cwj mem steganographic thiab ua ib qho cim rau ntawm daim ntawv ntim.Feem ntau, tus number case tsis muaj qhov cim tseg.Thaum qhov kub thiab txias, cov ntawv sau yuav tshwm sim, kom nws tuaj yeem txiav txim siab seb lawv puas raug tshuaj tua kab mob.Kev npaj ntawm steganographic number case: 88ml distilled dej, 2g chlorinated pob zeb diamond (CoC126H2O), thiab 10ml ntawm 30% hydrochloric acid.
