Kunezinhlobo eziningana zama-thermometer, ezinye zazo zaziwa njenge ama-thermometer elabhorethri. Amadivayisi wokulinganisa asetshenziselwa ukuqapha ngokunembile nokulawula amazinga okushisa kuma-laboratories. Ziwusizo kakhulu ocwaningweni oluningi oludinga ukwenziwa emazingeni okushisa athile.
Njengoba izinhlelo ezisetshenziswa kuzo zibucayi impela, hhayi noma yiluphi uhlobo lwe-thermometer olusebenzayo. Lawa ma-thermometer aselebhu ngokuvamile anakho ukuthembeka okukhulu, ngaphezu kokumelana nokuphepha ukusetshenziswa kulezi zindawo zesayensi.
Yini i-thermometer yaselebhu?
I-thermometer yaselabhorethri iyi-a idijithali noma i-analog thermometer isetshenziswe njengezilinganiso ezivivinyweni zaselabhoratri lapho izinga lokushisa lihambisana khona kakhulu. Ngakho-ke, kufanele ziqonde ngqo, zinikeze imininingwane esondele kakhulu ekushiseni kwangempela ngangokunokwenzeka, kanye nokumelana nezimo ezithile, njengokugqwala uma kusetshenziswa ama-asidi, amazinga okushisa kakhulu lapho kwenziwa khona ukuhlolwa, njll.
Yize zenzelwe umphakathi wesayensi, kuya ngokuya kuthengwa ekhaya kubenzi noma kubantu abenza izivivinyo ezithile zasekhaya lapho badinga ukuqapha izinga lokushisa ukuze bangashintshi imiphumela yalokho abakwenzayo.
Ngaphezu kwalokho, la ma-thermometer aselebhu kufanele abe nochungechunge lwezinto eziyisisekelo zokunakekelwa okulungile ukugcinwa kanye nokugcinwa umshuwalense. Ngokwesibonelo:
- Ukuphawulwa kwe-thermometer yaselebhu ukuyikhomba ngokuya ngezici zayo.
- Inhlanzeko ukuze kungabikho mkhondo wezinto zamakhemikhali ezingaguqula ezinye izivivinyo lapho usebenzisa khona i-thermometer efanayo.
- Hlala uhlonipha ububanzi bokusebenza obuphakeme nobuncane obucaciswe ngumenzi.
- Ukuvikelwa uma kungenzeka kusetshenziswe ngaphakathi kwabahlukumezi.
- Ukubeka endaweni ephephile ukugwema ukonakala.
- Ukulinganisa njalo ukuqinisekisa ukuthi iyaqhubeka nokugcina ukunemba kwayo nokwethembeka kwayo.
Izicelo Zokushisa Kwelebhu
I-Las izicelo zethemomitha laselebhu zingahluka kakhulu. Kunenqwaba yezivivinyo noma izivivinyo lapho kudingeka khona ukulawula izinga lokushisa, kusukela kulezo eziyisisekelo kakhulu lapho usebenza khona ngezinyathelo eziphakathi kwezimo ezahlukahlukene zendaba, ezinjengezimo eziqinile, eziwuketshezi nezinegesi, kuya kwezinye lapho kwenziwa khona izixazululo emazingeni athile okushisa, njll.
Isibonelo, zingasetshenziselwa uku:
- Lawula ukushisa kwe- izinguquko zokuhlanganiswa kwezimo zendaba: ukuxubana (okuqinile kuya kuketshezi), ukuqiniswa (uketshezi kuya kokuqinile), ukufuthiswa (uketshezi kuya kugesi), ukufingqa (igesi kuya kuketshezi), isikhuthazi (okuqinile kuya kugesi) nokubuyisela emuva i-sublimation (igesi iye kuqinile).
- Usayizi izakhiwo zomzimba okokusebenza ngokuya ngezinga lokushisa elikulo.
- Ukulawulwa kwe- izinqubo zamakhemikhali okudinga ukuthuthuka ezingeni lokushisa elithile. Isibonelo, ukusabela okuthile kwe-enzymatic.
