I-Digethion Tube Traetauls: Amaphuzu ama-3 abalulekile ezokuphepha

Amashubhu wokugayaziyizakhi ezibalulekile kuzilungiselelo zelebhu, ikakhulukazi ezinqubweni ezibandakanya ukugaya i-microwave noma ukuvimba ukugaya amasistimu wokugaya. Lawa amashubhu asetshenziselwa ukwehlisa amasampula ayinkimbinkimbi emafomu alula ukuze ahlaziywe ngezinto ezahlukahlukene zamakhemikhali. Kodwa-ke, ukuphatha amashubhu okugaya kudinga ukunakwa ngokucophelela izinqubo zokuphepha nezinqubo zokusebenza ukuze kuqinisekiswe ukuphepha komuntu kanye nobuqotho besampula.

Sebenzisa ithuluzi lokugaya elinikezelwe ekuhlaziyweni kwekhwalithi yamanzi futhi ulilondoloze ngesikhathi ukuze uqinisekise umphumela wokushisa umfaniswano. Abantu abaningi basebenzisa ichibi elisinki noma lokushisa lamanzi okushisa njalo lokugaya, okungalungile. Ukufudumeza kweI-COD test tube kufuthelwa kusuka phansi bese ukushisa kudluliswa kuyo yonke ishubhu. Izimo zokugaya izinto ezilandelayo zizodala izinga lokushisa elingalingani, elizoholela ekuqhumeni kweshubhu.

Ukuze ufunde kabanzi ngemiyalo kanye nezindlela zokuphepha zokusebenzisa amashubhu wokuhlola ama-COC, ungachofoza kule ndatshana:"Amashubhu wokuhlola amaCod: Imiyalo Nezindlela Zokuqapha"

1. I-heating block yensimbi yokugaya ayikho ezansi noma izikhundla ezimbalwa zokushisa yi-asymmetrical.

2. Ubukhulu noma izinto ezibonakalayo zensimbi eziqhuba ukushisa kwehlukile.

I-3. Ukugcotshwa kwensimbi yokugaya kukhulu kakhulu futhi i-tube ixhumana ngakolunye uhlangothi hhayi ukuxhumana nokunye.

Ngaphambi kokuhlola isampula, qiniseka ukuthatha izindlela zokuzivikela, gqoka ama-goggles, izingubo zokuvikela namagilavu, bese unaka ngokukhethekile ezindaweni ezintathu ezibalulekile.

1. Lapho ubeka i-tube yokuhlola kuthuluzi lokugaya.Lapho ubeka ishubhu lokuhlola, kufanele ibekwe kancane ukugwema ukuqhuma okubangelwa ukushayisana okunobudlova kwe-afuthi yokugaya ishubhu elinomgodi wokugaya. Ukuthatha ukuzimisela kwenkomba ye-COD yesampula yamanzi njengesibonelo, ngoba amanye amakhemikhali anesisindo namanye amakhemikhali amakhemikhali angezelwe kakhulu, kungahle kube nesampula ukubilisa ngesikhathi sokugaya futhi kubangele ukugaya ishubhu. Ngakho-ke, isampula yamanzi kufanele ixutshwe ngokulinganayo ngaphambi kokugaya ukuvikela ishubhu lokugaya kusuka ekuqhuti.

2. Ngesikhathi sokugaya kweshubhu lokuhlola.Qiniseka ukuthi isembozo esivikelayo sensimbi yokugaya sivaliwe ngokuqinile, gqoka izinyathelo zokuvikela lapho ubheka, cisha amandla ngokushesha uma ukuvuza noma ukukala kutholakale ngaphambi kokucutshungulwa.

3. Ngesikhathi sokupholisa kweshubhu lokuhlola.Ukudluliselwa kwengilazi ukushisa kancane kancane, nokushisa okungazelelwe nokupholisa kuzodala amazinga okushisa angaphakathi nangaphandle, azokwenza ukuthi ibhodlela lengilazi liqhume. Ukushisa okubandayo okubandayo nokukhulu kufanele kugwenywe. Kunconywa ukukhulisa kancane kancane izinga lokushisa kancane. Kunconywa ukupholisa kwemvelo lapho kupholisa (abakhiqizi abangeniswayo njenge-hach bancoma ukuphola kwemvelo) Qaphela: Uma kudingeka ukupholisa okusheshayo, uma izinga lokupholisa liyadingeka ngaphansi kwama-degree angama-10-50 ukuze apholile ama-10 degrees. Uma izinga lokushisa lingaphezulu kwama-degree ayi-10, lingaphola ngokushesha ngamanzi ahlanzekile ekushiseni kwegumbi.

Ngeminye imininingwane ngamashubhu wokuhlola ama-COD kanye nezicelo zawo ekuhlaziyweni kwamanzi, bhekani kulesi sihloko:"I-COD Test Tube isetshenziswa kanjani ekuhlaziyweni kwamanzi."

Amashubhu okugaya amathuluzi anamandla ukuhlaziya amakhemikhali, kepha ukusetshenziswa kwawo okuphephile futhi okusebenzayo kudinga ukunakwa ngokucophelela imininingwane. Ngokulandela izinyathelo zokuphepha ngenhla (Ukuqinisekisa ukubekwa okufanele, ukuqapha ngokuqapha, nokusingathwa ngokucophelela ngesikhathi sokupholisa), abasebenzi belebhu banganciphisa ubungozi ngenkathi kukhulisa ikhwalithi yemiphumela yokuhlaziya. Njengoba ubuchwepheshe buyaqhubeka nokuvela, ukuqonda lezi zimiso zokuphepha kuhlala kubalulekile ekuthuthukiseni ucwaningo kanye nokuqinisekisa indawo yokusebenza ephephile.
