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 sensimbi sihlanganisa ikakhulukazi izingxenye ezilandelayo:
1. Ishidi le-electrode eliphezulu 2. Ishidi le-electrode eliphansi 3. Ibhokisi lokuhlola 4. Iphaneli yokulawula
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.
GB24540-2009 Izingubo zokuzivikela Izingubo zokuzivikela ezisekelwe kumakhemikhali e-asidi Isithasiselo A
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
1. Xhuma ukunikezwa kwamandla kwethuluzi nentambo yamandla ohlinzekiwe bese uvula iswishi yamandla.
2. Sabalalisa isampula elilungisiwe lacaba 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
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.
