I-Isopropanol, eyaziwa nangokuthi2-propanol, iwuketshezi olungenambala futhi olusobala olunephunga elinamandla. Kuyi-solvent ephilayo esetshenziswa kakhulu. Ngenxa yezakhiwo zayo zamakhemikhali eziyingqayizivele, isetshenziswa kabanzi emkhakheni wezokwelapha, izimonyo, okokugcotshwa nezincibilikisayo. Nokho, yini okufanele icatshangelwe lapho uthenga isopropanol?

Qonda isidingo kanye namazinga ekhwalithi:

Ngaphambi kokuthenga i-isopropanol, kubalulekile ukuba nokuqonda okucacile kwesidingo sakho futhi unqume amazinga ekhwalithi ye-isopropanol ethengiwe. Lokhu kungakusiza uqonde kangcono umkhiqizo owufunayo futhi ugweme ukuthenga imikhiqizo engafanele.

Khetha umthengisi onedumela elihle:

Lapho ukhetha umdayisi, kubalulekile ukuqinisekisa ukuthi ungumdayisi osemthethweni. Ngokuvamile, ulwazi lomdayisi oluthembekile lungatholakala ezinhlanganweni zemboni noma ezisekelweni ze-inthanethi ezaziwayo.

Intengo akuyona ukuphela kwento okufanele icatshangelwe:

Lapho uthengaisopropanol, intengo akufanele kube ukuphela kokucatshangelwa. Ikhwalithi kanye nesevisi kubaluleke ngokulinganayo. Imikhiqizo enenani eliphansi ayiyona inketho engcono kakhulu, ngakho ukucatshangelwa ngokucophelela kuyadingeka.

Naka ukupakishwa nokugcina:

Lapho uthenga i-isopropanol, kubalulekile ukucabangela ukuthi indawo yokupakisha neyokugcina ifanelekile. Ngisho ne-isopropanol yekhwalithi ephezulu ingaba nekhwalithi yayo engcupheni uma ingagcinwa kahle.

Ekuphetheni, kunezici eziningi okufanele zicatshangelwe lapho uthenga i-isopropanol. Amakhasimende kufanele abuyekeze ngokucophelela izindinganiso zekhwalithi, ukupakishwa, nendawo yokugcina umkhiqizo, futhi akhethe umdayisi ohloniphekile ukuze aqinisekise ukuthenga okwanelisayo.
