YYT-T453 Cov Khaub Ncaws Tiv Thaiv Anti-Acid Thiab Alkali Test System
Txoj kev siv hluav taws xob thiab lub cuab yeej teem sijhawm tsis siv neeg siv los sim lub sijhawm nkag mus ntawm cov khaub ncaws tiv thaiv cov kua qaub thiab alkali. Cov qauv raug muab tso rau ntawm cov ntawv electrode sab saud thiab sab qis, thiab cov xov hlau conductive txuas nrog daim ntawv electrode sab saud thiab kov lub ntsej muag sab saud ntawm cov qauv. Thaum qhov xwm txheej nkag mus, lub voj voog raug qhib thiab lub sijhawm nres.
Cov qauv ntawm cov cuab yeej feem ntau suav nrog cov khoom hauv qab no:
1. Daim ntawv electrode sab saud 2. Daim ntawv electrode sab hauv qab 3. Lub thawv kuaj 4. Vaj huam sib luag tswj
1. Lub sijhawm sim: 0 ~ 99.99 feeb
2. Cov qauv qhia tshwj xeeb: 100mm × 100mm
3. Lub hwj chim muab hluav taws xob: AC220V 50Hz
4. Kev sim ib puag ncig: kub (17 ~ 30) ℃, qhov av noo: (65 ± 5)%
5. Cov tshuaj reagents: Cov khaub ncaws tiv thaiv acid cog lus yuav tsum tau sim nrog 80% sulfuric acid, 30% hydrochloric acid, 40% nitric acid; cov khaub ncaws tiv thaiv inorganic alkali yuav tsum tau sim nrog 30% sodium hydroxide; cov khaub ncaws tiv thaiv electrodeless acid yuav tsum tau sim 80% Sulfuric acid, 30% hydrochloric acid, 40% nitric acid, thiab 30% sodium hydroxide.
GB24540-2009 Cov khaub ncaws tiv thaiv cov khaub ncaws tiv thaiv cov tshuaj lom neeg uas muaj kua qaub thiab cov tshuaj lom neeg ntxiv A
1. Kev kuaj: Rau txhua qhov kev daws teeb meem, coj 6 qhov qauv los ntawm cov khaub ncaws tiv thaiv, qhov kev qhia tshwj xeeb yog 100mm × 100m,
Ntawm lawv, 3 yog cov qauv tsis muaj qhov sib txuas thiab 3 yog cov qauv sib koom ua ke. Cov kab sib txuas ntawm cov qauv sib txuas yuav tsum nyob hauv nruab nrab ntawm cov qauv.
2. Qauv ntxuav: saib GB24540-2009 Appendix K rau cov txheej txheem ntxuav thiab cov kauj ruam tshwj xeeb
1. Txuas lub hwj chim ntawm lub cuab yeej nrog lub hwj chim uas muab los thiab tig lub qhov hluav taws xob.
2. Nthuav cov qauv uas tau npaj tiav kom tiaj tus ntawm cov phaj electrode sab saud thiab sab hauv qab, tso 0.1 mL ntawm cov tshuaj reagent los ntawm lub qhov puag ncig raws cov xov hlau conductive mus rau saum npoo ntawm cov qauv, thiab nias lub pob "Pib/Nres" tib lub sijhawm kom pib lub sijhawm. Rau cov qauv uas muaj cov xov hlau conductive, cov xov hlau conductive raug muab tso rau ntawm cov xov hlau thiab cov tshuaj reagents raug tso rau ntawm cov xov hlau.
3. Tom qab nkag mus rau hauv lub cuab yeej, lub cuab yeej yuav nres lub sijhawm, lub teeb qhia qhov nkag mus rau hauv lub cuab yeej yuav ci, thiab lub tswb ceeb toom yuav nrov. Lub sijhawm no, lub sijhawm uas nws nres yuav raug kaw cia.
4. Cais cov electrodes sab saud thiab sab hauv qab thiab nias lub pob "reset" kom rov qab kho qhov pib ntawm lub cuab yeej. Tom qab ib qho kev sim tiav lawm, ntxuav cov seem ntawm cov electrode thiab cov xov hlau conductive.
5. Yog tias muaj xwm txheej tsis tau xav txog thaum lub sijhawm sim, koj tuaj yeem nias lub pob "Pib/Nres" ncaj qha kom nres lub sijhawm thiab muab lub tswb ceeb toom.
6. Rov ua cov kauj ruam 2 txog 4 kom txog thaum tag nrho cov kev sim tiav. Tom qab kev sim tiav lawm, tua lub zog ntawm lub cuab yeej.
7. Cov txiaj ntsig ntawm kev xam:
Rau cov qauv tsis muaj qhov tsis xws luag: cov kev nyeem ntawv tau cim ua t1, t2, t3; lub sijhawm nkag mus
Rau cov qauv nrog cov seams: cov nyeem tau raug kaw ua t4, t5, t6; lub sijhawm nkag mus
1. Cov tshuaj siv rau hauv kev sim no muaj zog heev. Thov ua tib zoo saib xyuas kev nyab xeeb thiab ua raws li kev tiv thaiv thaum lub sijhawm sim.
2. Siv lub dropper los pipette cov tshuaj kuaj thaum lub sijhawm kuaj.
3. Tom qab qhov kev sim, ntxuav qhov chaw ntawm lub rooj zaum xeem thiab lub cuab yeej raws sijhawm kom tiv thaiv kev xeb.
4. Cov cuab yeej yuav tsum tau grounded kom ntseeg tau.
