DRK-T453 Kev Tiv Thaiv Cov Khaub Ncaws Anti-Acid Thiab Alkali Test System Ua Haujlwm Phau Ntawv-Penetration Time Tester

Txoj cai ua haujlwm

Cov txheej txheem conductivity thiab tsis siv neeg lub sij hawm ntaus ntawv yog siv los ntsuas lub sij hawm nkag mus ntawm cov ntaub tiv thaiv khaub ncaws rau cov kua qaub thiab alkali tshuaj.Cov qauv yog muab tso rau nruab nrab ntawm cov nplooj ntawv electrode sab sauv thiab qis, thiab cov hlau conductive txuas nrog rau daim ntawv electrode sab saud thiab yog nyob rau hauv kev sib cuag nrog cov saum npoo ntawm cov qauv.Thaum qhov tshwm sim nkag tau tshwm sim, lub Circuit Court yog qhib thiab lub sij hawm nres.

Cov cuab yeej siv

Cov qauv ntsuas feem ntau suav nrog cov hauv qab no:

1. Sab saum toj electrode sheet 2. Lower electrode sheet 3. Test box 4. Control vaj huam sib luag

Technical Parameters

1. Lub sij hawm xeem: 0 ~ 99.99 min

2. Specimen specification: 100mm × 100mm

3. Fais fab mov: AC220V 50Hz

4. Kev ntsuas ib puag ncig: kub (17 ~ 30) ℃, txheeb ze av noo: (65 ± 5)%

5. Reagents: Kev cog lus acid tiv thaiv khaub ncaws yuav tsum tau kuaj nrog 80% sulfuric acid, 30% hydrochloric acid, 40% nitric acid;inorganic alkali tiv thaiv khaub ncaws yuav tsum tau kuaj nrog 30% sodium hydroxide;Cov khaub ncaws tiv thaiv electrodeless acid yuav tsum yog 80% Sulfuric acid, 30% hydrochloric acid, 40% nitric acid, thiab 30% sodium hydroxide raug kuaj.

Cov qauv siv tau:

GB24540-2009 Cov khaub ncaws tiv thaiv Acid-base tshuaj tiv thaiv khaub ncaws Appendix A

Npaj tus qauv

1. Sampling: Rau txhua qhov kev sim tshuaj, coj 6 cov qauv los ntawm cov khaub ncaws tiv thaiv, qhov tshwj xeeb yog 100mm × 100m,

Ntawm lawv, 3 yog cov qauv seamless thiab 3 yog cov qauv sib koom ua ke.Lub seam ntawm cov qauv seamed yuav tsum nyob hauv nruab nrab ntawm cov qauv.

2. Qauv ntxuav: saib GB24540-2009 Daim Ntawv Ntxiv K rau kev ntxuav tshwj xeeb thiab cov kauj ruam

Etxheej txheem xperiment

1. Txuas lub hwj chim ntawm lub ntsuas hluav taws xob nrog cov khoom siv hluav taws xob thiab qhib lub hwj chim hloov.

2. Tshaj tawm cov qauv npaj ncaj nraim nruab nrab ntawm cov phaj sab sauv thiab sab qis, poob 0.1 mL ntawm cov reagent los ntawm lub qhov puag ncig raws li cov xaim xaim mus rau saum npoo ntawm cov qauv, thiab nias lub pob "Start / Nres" tib lub sijhawm pib. sij hawm.Rau cov qauv nrog cov seams, cov xaim hluav taws xob tau muab tso rau ntawm cov seams thiab cov tshuaj reagents poob rau ntawm cov seams.

3. Tom qab kev nkag mus, qhov ntsuas yuav nres lub sijhawm, lub teeb pom kev nkag mus tau qhib, thiab lub tswb nrov.Lub sijhawm no, lub sijhawm thaum nws nres yog kaw.

4. Sib cais cov electrodes sab sauv thiab sab qis thiab nias lub pob "rov qab" kom rov qab pib lub xeev ntawm lub ntsuas.Tom qab ib qho kev sim ua tiav, ntxuav cov seem ntawm cov electrode thiab cov xaim hluav taws xob.

5. Yog tias muaj qhov xwm txheej tsis txaus ntseeg thaum lub sijhawm sim, koj tuaj yeem nias lub pob "Start/Stop" ncaj qha kom nres lub sijhawm thiab muab lub tswb.

6. Rov ua cov kauj ruam 2 mus rau 4 kom txog thaum tag nrho cov kev xeem tiav.Tom qab qhov kev xeem tiav lawm, tua lub hwj chim ntawm qhov ntsuas.

7. Cov txiaj ntsig suav:

Rau cov qauv seamless: cov ntawv nyeem yog cim t1, t2, t3;lub sij hawm nkag

Rau cov qauv nrog seams: cov ntawv nyeem tau sau ua t4, t5, t6;lub sij hawm nkag

Cov kev ceev faj

1. Cov tshuaj ntsuam xyuas siv nyob rau hauv qhov kev xeem yog heev corrosive.Thov ua tib zoo saib xyuas kev nyab xeeb thiab ntsuas kev tiv thaiv thaum kuaj.

2. Siv lub dropper rau pipette cov tshuaj ntsuam xyuas thaum kuaj.

3. Tom qab qhov kev xeem, ntxuav qhov saum npoo ntawm lub rooj ntev zaum thiab cov cuab yeej ntsuas lub sij hawm los tiv thaiv corrosion.

4. Cov cuab yeej yuav tsum muaj kev ntseeg siab.
