Izinto eziqinileyo kunye nezambuku kufuneka zicolwe ukuba ubungakanani bazo obuziinkozo burhabaxa kakhulu ukulungiselela iinkqubo ezinjengokuhlalutya, ukuxuba, okanye ukusetyenzwa ngakumbi. Iindlela ezifana ne-spectroscopy kunye ne-chromatography zisetyenziselwa ukuqinisekiswa komgangatho. Ekubeni ubukhulu bengqolowa buhlala buchaphazela iimpawu zemveliso (umzekelo, ukutsalwa, ukuhluzwa, ukufunxa), izinto zomhlaba nazo ziyimfuneko kwibhubhoratri yophuhliso lwemveliso kunye neenkqubo zokuvelisa.
Ngokuqhelekileyo kufunwa ukuba izinto zenziwe phantsi "kwi-powder-fine" - igama elithi, nangona kunjalo, alinayo inkcazo ecacileyo, ekubeni izinto ezininzi ezifana nomgubo wokuhlamba, i-coffee powder kunye ne-baking powder ziyahluka kakhulu ngobukhulu bengqolowa kunye nokusabalalisa.
Ngokukwanjalo, iisampulu zaselabhoratri ziyafuneka ukuba zicolwe “ngokucokisekileyo kangangoko,” nto leyo, nangona kunjalo, ifuna ukusetyenziswa kwamandla aphezulu, ixesha elide, kwaye ngaloo ndlela kwandiswe iindleko. I-motto ke ngoko: ayilunganga kunokuba kunokwenzeka, kodwa ilungile kuphela njengoko kuyimfuneko.
Ukongeza, imathiriyeli yesampulu kufuneka ibe neconeness efunekayo yendlela yokuhlalutya ngokufanelekileyo, edla ngokuba phakathi kwe-20 µm kunye ne-2 mm.
Ukuze kusetyenziswe eyona nto ilungileyo, umatshini wesixhobo kufuneka ulungelelaniswe nendlela yokwaphuka kwesixhobo. Ke ngoko, iipropathi zezinto ezibonakalayo-ezinje ngoxinaniso, ukuqina, ukungaguquguquki, ukufuma okushiyekileyo, isiqulatho samafutha, ubuntununtunu bobushushu, i-agglomeration behagure, kunye nokusabela komphezulu-kufuneka zihlolwe ngononophelo phambi kokuba kuqwalaselwe. Uhlalutyo olulandelayo kufuneka nalo luqwalaselwe.
Ulwazi oluthe vetshe lunokufumaneka apha:
Izinto eziqinileyo kunye nezambuku kufuneka zicolwe ukuba ubungakanani bazo boqobo obuziinkozo burhabaxa kakhulu ukulungiselela iinkqubo zokuhlalutya, iinkqubo zokuxuba, okanye ukuqhubekeka phambili. Ukudibanisa kubaluleke kakhulu kwiilabhoratri, njengoko ubungakanani beenkozo buchaphazela ngokuthe ngqo iipropathi zemveliso ezinje ngokutsalwa, ukuhluzwa, okanye ukufunxa.

I-fineness efunekayo ixhomekeke kwindlela ekhethiweyo yokuhlalutya. Ngokuqhelekileyo, iimfuno ziphakathi kwe-20 µm kunye ne-2 mm. Ukugqithisa kufuneka kuphetshwe, njengoko kudla amandla kunye nexesha elingeyomfuneko.
Ukuqhawula okusebenzayo, i Iimpawu ezibonakalayo Izinto ezinje ngoxinaniso, ukuqina, umxholo wokufuma, umxholo wamafutha, ukungaguquguquki, ukuziphatha kobushushu, kunye nokudityaniswa kufuneka kuthathelwe ingqalelo. Indlela yokuhlalutya ekhethiweyo iphinda idlale indima ebalulekileyo ekukhetheni inkqubo efanelekileyo yokuhambisa.
Ukukhethwa kwezinto ezifanelekileyo zokugaya (umzekelo, insimbi, i-ceramic, i-tungsten carbide) ichaphazela kakhulu ubomi benkonzo kunye nokusebenza kwelitye. Ngokuxhomekeke kwinjongo yokuhlalutya, ukungcoliseka kwezinto ezinokubakho ngenxa yokukrazula kufuneka kuqwalaselwe.
