Ungashintsha kanjani phakathi kokuhlukaniswa kwesigaba esijwayelekile nokuhlehliswa kwesigaba sokuhlukaniswa?
Kuphakathi kokuthi ushintshe usuke ekwehlukaneni kwesigaba esivamile uye ekwehlukanisweni kwesigaba esihlehlisiwe noma okuphambene nalokho, i-ethanol noma i-isopropanol kufanele isetshenziswe njengesixazululi soshintsho ukuze kukhishwe ngokuphelele noma yiziphi izincibilikisi ezingahlangani kushubhu.

Kwenziwa kanjani uma ingcindezi yesistimu ikhuphuka kakhulu?
1. Izinga lokugeleza kwesistimu liphezulu kakhulu kukholomu yefuleshi yamanje.
2. Isampula inokuncibilika okungekuhle futhi imvula isuka esigabeni esihambayo, ngaleyo ndlela kubangele ukuvaleka kwamashubhu.
3. Esinye isizathu sibangela ukuvaleka kwamashubhu.

Kwenziwa kanjani lapho i-solvent itholakala ivuza esisekelweni somphathi wekholomu lapho umnikazi wekholomu ephakamisa?
Ukuvuza kwe-solvent kungase kube ngenxa yezinga le-solvent ebhodleleni likadoti liphakeme kunobude besixhumi esisekelweni sesibambi sekholomu.
Beka ibhodlela likadoti ngaphansi kwendawo yokusebenza yensimbi, noma yehlise ngokushesha isibambi sekholomu ngemva kokukhipha ikholomu.

Uyini umsebenzi wokuhlanza "Ekuhlukaniseni kwangaphambili"? Ingabe kufanele kwenziwe?
Lo msebenzi wokuhlanza udizayinelwe ukuhlanza ipayipi lesistimu ngaphambi kokuthi kuqaliswe ukuhlukaniswa. Uma "ukuhlanza ngemuva" kwenziwe ngemuva komdlalo wokugcina wokuhlukanisa, lesi sinyathelo singeqiwa. Uma kungenziwanga, kunconywa ukuthi wenze lesi sinyathelo sokuhlanza njengoba uyalwe ukwaziswa kwesistimu.
