YYT-T453 Cov khaub ncaws tiv thaiv tiv thaiv acid thiab alkali xeem system
Cov cuab yeej no tshwj xeeb tsim los ntsuas cov kua tshuaj tiv thaiv kev ua haujlwm ntawm cov ntaub tiv thaiv cov khaub ncaws rau cov kua qaub thiab alkali tshuaj.
1. Semi-cylindrical plexiglass pob tshab tank, nrog ib txoj kab uas hla ntawm (125 ± 5) hli thiab ntev ntawm 300 hli.
2. Txoj kab uas hla ntawm koob txhaj tshuaj yog 0.8mm; lub taub hau yog tiaj.
3. Tsis siv neeg txhaj tshuaj, nruam txhaj tshuaj ntawm 10mL reagent nyob rau hauv 10s.
4. Tsis siv neeg lub sij hawm thiab tswb system; LED zaub kuaj lub sijhawm, qhov tseeb 0.1S.
5. Fais fab mov: 220VAC 50Hz 50W
GB24540-2009 "Cov khaub ncaws tiv thaiv, cov khaub ncaws tiv thaiv acid-puag tshuaj"
1. Txiav ib daim ntawv lim dej thiab cov yeeb yaj kiab pob tshab txhua qhov loj ntawm (360 ± 2) hli × (235 ± 5) hli.
2. Muab cov yeeb yaj kiab uas hnyav rau hauv lub tank pob tshab, npog nrog cov ntawv lim, thiab ua tib zoo rau ib leeg. Ceev faj kom tsis txhob tawm ntawm qhov khoob lossis wrinkles, thiab xyuas kom meej tias qhov qis kawg ntawm cov pob tshab tawv zawj, pob tshab zaj duab xis, thiab cov ntawv lim dej ntws tawm.
3. Muab cov qauv tso rau ntawm daim ntawv lim kom lub qhov ntev ntawm cov qauv yog sib npaug mus rau sab ntawm cov zawj, cov txheej txheem sab nraud yog nce siab, thiab sab folded ntawm cov qauv yog 30 hli dhau ntawm qhov qis kawg ntawm qhov zawj. Ua tib zoo xyuas cov qauv kom paub tseeb tias nws qhov chaw haum nruj nrog cov ntawv lim, tom qab ntawd kho cov qauv ntawm qhov nyuaj pob tshab zawj nrog clamp.
4. Ntsuas qhov hnyav ntawm lub khob me me thiab sau nws li m1.
5. Muab lub khob me me tso rau hauv qab ntawm ntug ntawm cov qauv kom paub meej tias tag nrho cov reagents ntws los ntawm cov qauv tuaj yeem sau tau.
6. Paub meej tias "lub sij hawm sim" timer ntaus ntawv ntawm lub vaj huam sib luag yog teem rau 60 vib nas this (tus qauv yuav tsum tau).
7. Nias lub "hloov fais fab" ntawm lub vaj huam sib luag mus rau "1" txoj hauj lwm kom tig lub ntsuas hluav taws xob.
8. Npaj cov reagent kom cov koob txhaj tshuaj tau muab tso rau hauv cov reagent; nias lub pob "aspirate" rau ntawm lub vaj huam sib luag, thiab lub cuab yeej yuav pib khiav rau aspiration.
9. Tom qab lub aspiration tiav lawm, tshem tawm lub reagent thawv; nias lub pob "Ntxhais" ntawm lub vaj huam sib luag, qhov ntsuas yuav cia li txhaj tshuaj reagents, thiab lub sijhawm "test" timer yuav pib lub sijhawm; txhaj tshuaj tiav tom qab li 10 vib nas this.
10. Tom qab 60 vib nas this, lub buzzer yuav tswb, qhia tias qhov kev xeem tiav.
11. Coj mus rhaub rau ntawm ntug ntawm lub pob tshab groove ua kom cov reagent raug tshem tawm ntawm lub folded ntug ntawm tus qauv plam tawm.
12. Ntsuas qhov hnyav tag nrho m1 / ntawm cov reagents sau rau hauv lub khob me me thiab lub khob, thiab sau cov ntaub ntawv.
13. Kev ua tiav:
Cov kua tshuaj tiv thaiv index yog xam raws li cov qauv hauv qab no:
I- kua repellent index,%
m1-Qhov loj ntawm lub khob me me, hauv grams
m1'-qhov loj ntawm reagents sau nyob rau hauv lub me beaker thiab lub beaker, nyob rau hauv grams
m-qhov loj ntawm reagent poob mus rau tus qauv, hauv grams
14. Nias lub "hloov fais fab" mus rau "0" txoj hauj lwm kom lub hwj chim tawm ntawm qhov ntsuas.
15. Kev xeem tiav.
1. Tom qab qhov kev xeem tiav lawm, yuav tsum tau ua cov txheej txheem ntxuav thiab tshem tawm cov khoom seem! Tom qab ua tiav cov kauj ruam no, nws yog qhov zoo tshaj kom rov ua dua cov kev tu nrog tus neeg saib xyuas tu.
2. Cov kua qaub thiab alkali yog corrosive. Cov neeg ua haujlwm kuaj yuav tsum hnav cov hnab looj tes acid/alkali-proof kom tsis txhob raug mob ntawm tus kheej.
3. Lub hwj chim ntawm cov cuab yeej yuav tsum tau ua kom zoo hauv av!
