I-DRK-T453 Impahla Evikelayo I-Anti-Acid Ne-Alkali Imanuwali Yokusebenza Yesistimu Yokuhlola—Isihloli Sesikhathi Sokungena

Isimiso sokusebenza

Indlela ye-conductivity kanye nedivayisi yesikhathi ezenzakalelayo isetshenziselwa ukuhlola isikhathi sokungena kwezingubo zokuvikela zendwangu zamakhemikhali ane-asidi ne-alkali.Isampula ibekwe phakathi kwamashidi e-electrode angaphezulu naphansi, futhi intambo yokuqondisa ixhunywe eshidini le-electrode eliphezulu futhi ixhumene nendawo engaphezulu yesampula.Lapho kwenzeka into engena ngaphakathi, isifunda siyavulwa futhi isikhathi siyama.

Isakhiwo sezinsimbi

Isakhiwo sensimbi sihlanganisa ikakhulukazi izingxenye ezilandelayo:

1. Ishidi le-electrode eliphezulu 2. Ishidi le-electrode eliphansi 3. Ibhokisi lokuhlola 4. Iphaneli yokulawula

Imingcele Yezobuchwepheshe

1. Ibanga lesikhathi sokuhlola: 0～99.99min

2. Ukucaciswa kwesifanekiso: 100mm×100mm

3. Ukunikezwa kwamandla: AC220V 50Hz

4. Indawo yokuhlola: izinga lokushisa (17～30)℃, umswakama ohlobene: (65±5)%

5. Ama-reagents: Izingubo zokuvikela i-asidi yesithembiso kufanele zihlolwe ngo-80% sulfuric acid, 30% hydrochloric acid, 40% nitric acid;Izingubo zokuzivikela ze-alkali ezingaphili kufanele zihlolwe nge-30% ye-sodium hydroxide;Izingubo zokuvikela i-electrodeless acid kufanele zibe ngu-80% we-Sulfuric acid, 30% hydrochloric acid, 40% nitric acid, kanye no-30% we-sodium hydroxide.

Amazinga asebenzayo:

GB24540-2009 Izingubo zokuzivikela Izingubo zokuzivikela ezisekelwe kumakhemikhali e-asidi Isithasiselo A

Lungiselela isampula

1. Isampula: Ngesixazululo ngasinye sokuhlola, thatha amasampula ayi-6 engutsheni yokuzivikela, ukucaciswa ngu-100mm×100m,

Phakathi kwazo, ezi-3 zingamasampuli angenamthungo kanti ezi-3 zingamasampula ahlangene.Umthungo wesampula esithungiwe kufanele ube phakathi nendawo yesampula.

2. Isampula yokugeza: bheka i-GB24540-2009 Appendix K mayelana nezindlela ezithile zokuwasha nezinyathelo

Einqubo ye-xperiment

1. Xhuma ukunikezwa kwamandla kwethuluzi nentambo yamandla ohlinzekiwe bese uvula iswishi yamandla.

2. Sabalalisa isampula elilungisiwe liphansi phakathi kwamapuleti e-electrode angaphezulu nangaphansi, wehlise u-0.1 mL we-reagent kusuka embotsheni eyindilinga eduze kwentambo yokuhambisa ukuya phezulu kwesampula, bese ucindezela inkinobho ethi "Qala/Misa" ngesikhathi esifanayo ukuze uqale. isikhathi.Ukuze uthole ama-specimens ane-seams, ucingo lwe-conductive lubekwe kuma-seams futhi ama-reagents awela emigqeni.

3. Emva kokungena, insimbi iyazimisa ngokuzenzakalelayo isikhathi, ukukhanya kwenkomba yokungena kuyakhanya, ne-alamu iyakhala.Ngalesi sikhathi, isikhathi lapho ima siyarekhodwa.

4. Hlukanisa ama-electrode aphezulu naphansi bese ucindezela inkinobho ethi "setha kabusha" ukuze ubuyisele isimo sokuqala sethuluzi.Ngemva kokuhlolwa okukodwa, hlanza okusele ku-electrode kanye nocingo oluqhubayo.

5. Uma kukhona noma yisiphi isimo esingalindelekile phakathi nokuhlolwa, ungacindezela ngokuqondile inkinobho ethi "Qala/Yeka" ukuze umise isikhathi futhi unikeze i-alamu.

6. Phinda izinyathelo 2 kuya kwezi-4 kuze kube yilapho kwenziwa zonke izivivinyo.Ngemva kokuphela kokuhlolwa, vala amandla ethuluzi.

7. Imiphumela yokubala:

Kumasampula angenamthungo: ukufundwa kumakwe ngokuthi t1, t2, t3;isikhathi sokungena

Kumasampula anama-seams: ukufundwa kuqoshwa njenge-t4, t5, t6;isikhathi sokungena

Izinyathelo zokuzivikela

1. Isixazululo sokuhlola esisetshenziswe ekuhlolweni sigqwala kakhulu.Sicela unake ukuphepha futhi uthathe izinyathelo zokuzivikela ngesikhathi sokuhlolwa.

2. Sebenzisa i-dropper ukuze wenze i-pipette isisombululo sokuhlola ngesikhathi sokuhlolwa.

3. Ngemva kokuhlolwa, hlanza ingaphezulu lebhentshi lokuhlola kanye nethuluzi ngesikhathi ukuze uvimbele ukugqwala.

4. Ithuluzi kufanele lisekelwe phansi ngokuthembekile.
