Xa uvutha, ukungcola kwe-inorganic kwisampulu kuzinzile (njenge-sodium chloride, i-potassium chloride, i-sodium sulfate, njl.), Ukuba kungekhona ngenxa yokutshisa kunye nokunyuka komphunga, le ndlela ingasetyenziselwa ukumisela uthuthu kwisampulu.

[Indlela yokumisela] Beka isigqubuthelo se-ceramic crucible (okanye i-nickel crucible) kwiziko lombane elinobushushu obuphezulu (okt, isithando sombane) okanye idangatye lerhasi, litshise libe kubunzima obungaguqukiyo malunga (malunga neyure enye), liyise kwisitshizi secalcium chloride. kwaye ipholile kwiqondo lokushisa. Isiciko se-crucible silinganiswe kunye kwibhalansi yohlalutyo kwaye sisethelwe kwi-G1 g.

Kwi-crucible esele ilinganisiwe, thatha isampuli ezifanelekileyo (kuxhomekeke kuthuthu kwisampulu, ebizwa ngokuba yi-2-3 grams), wathi ku-0.0002 grams, umlomo wesiciko se-crucible malunga neekota ezintathu, kunye nomlilo ophantsi ngokucothayo ukufudumala kwi-crucible, yenza isampuli ngokuthe ngcembe i-carbonization. , emva kwe-crucible kwisithando sombane (okanye i-gas flame), engekho ngaphantsi kwe-800℃ukutshisa kuqikelelo lobunzima obungaguqukiyo (malunga neeyure ezi-3), ifuduselwe kwi-calcium chloride drier, ipholiswe kubushushu begumbi, inobunzima. Kungcono ukutshisa emva kweeyure ezi-2, upholile, ulinganise, uze utshise iyure eli-1, emva koko upholile, ulinganise, ulinganisa ezimbini ngokulandelelana, ubunzima buphantse bungatshintshi, ngoko kuthetha ukuba kutshiswe ngokupheleleyo, ukuba ubunzima buyancipha. emva kokutshisa okwesibini, ngoko kufuneka kube yinto yesithathu yokutshisa, itshise ide ifane nobunzima obuqhubekayo, setha i-G grams.

(G-G1) / ubunzima besampulu x100= ngwevu%

[Qaphela] -Ubungakanani besampulu bunokumiselwa ngokwemali yothuthu kwisampulu, isampula yothuthu olungaphantsi, ingabizwa malunga ne-5 grams yesampuli, isampuli yothuthu, ingabizwa malunga ne-2 grams yesampuli.

2. Ubude bexesha lokutshisa buxhomekeke kubunzima besampuli, kodwa ukutshisa kufana nobunzima obuqhubekayo.

3. Umahluko wobunzima obutsha kabini ngokulandelelanayo ube ngcono ube kwi-0.3 mg engezantsi, umahluko omkhulu awunakudlula i-1 mg, kuthathwa njengoqikelelo kubunzima obuqhubekayo oko kukuthi.
