Imuphi umenzi we-capillary wensimbi engenasici ongcono? Yiziphi izici ezithinta ikhwalithi phakathi nenqubo yokukhiqiza?

Insimbi engagqwali capillary uhlobo olukhethekile ipayipi insimbi engagqwali. Intengo yayo iphakeme kakhulu kunaleyo yamapayipi ezimboni ajwayelekile. Uma kuqhathaniswa, inqubo yokukhiqiza ngaphezulu kwe-capillary yensimbi engenasici nayo ingcono.
I-capillary yensimbi engagqwali inesakhiwo esihle kanye nezidingo eziphezulu zokusetshenziswa, ngakho-ke le nto idinga ukuba nezinga eliphakeme lokuhlola ukukhiqiza ngesikhathi senqubo yokukhiqiza. Uma izidingo zingafinyelelwa, kulula ukuba nemikhiqizo enesici efana nokuvinjelwa kwe-capillary kanye nokuguqulwa, okuthinta ngokuqondile ukusetshenziswa okuvamile noma okungeke kusetshenziswe. Nazi ezinye izici ezithinta ikhwalithi ye-capillary yensimbi engagqwali.

Insimbi engagqwali capillary

Ngaphezu kwezakhiwo eziyisisekelo zemishini ezinjengamandla amahle okuqina, ukumelana nokugqwala nobulukhuni obukhulu,304 capillary tubefuthi inokubukeka kwekhwalithi ephezulu, okungukuthi, ukukhanya kwayo okungaphezulu kufinyelela ekuphakameni okujwayelekile. Kodwa-ke, kufanele kuqashelwe ukuthi ukukhanya kwamashubhu ensimbi engenasici enobubanzi obuncane kuzoncishiswa ngenxa yokusebenza okungalungile noma ukulungiswa okwanele ngesikhathi sokucubungula.
Isici esibalulekile esithinta izinga eliphezulu lamashubhu e-capillary ensimbi engagqwali okuqukethwe kwamafutha okweqile kwe-emulsion. I-Emulsion iyisixazululo sokucubungula amapuleti ensimbi engagqwali ezigayweni ezibandayo ezigoqayo, ezidlala indima ebalulekile ekubaleleni nasekupholiseni amapuleti ensimbi engagqwali. Kodwa-ke, uma i-emulsion iqukethe izingxenye zamafutha, amafutha azoqhekeka abe yikhabhoni emazingeni okushisa aphezulu. Uma amafutha e-emulsion engahlanjululwa ngesikhathi ngemuva kwe-carbonization ekushiseni okuphezulu, azoqoqa phezu kwe-tube futhi enze ama-indentations ngemva kokugoqa.
Ngenxa yokuthi i-emulsion yensimbi engagqwali ye-capillary iqukethe amafutha amaningi, izokwenziwa nge-carbonized futhi iqoqwe odongeni lwangaphakathi lwekhava yesondlo ngemva kokudonsa. Kwezinye izinqubo zokucubungula, lawa ma-carbon blacks azolethwa ebusweni beshubhu yensimbi engagqwali enobubanzi obuncane, ngaleyo ndlela avale ingaphezulu leshubhu futhi athinte ikhwalithi yokubukeka. Ngemuva kwesikhathi eside sokwelashwa, ukungcola okuningi okufana namafutha, i-carbon black kanye nothuli kuzoqoqana ku-convection plate kanye nesithando somlilo. Uma zingahlanzwa ngesikhathi, lokhu kungcola kuzophinde kuwele phezu kwepuleti lensimbi engagqwali.
Eqinisweni, ukwakheka kwamakhemikhali kanye nokuqedwa kwendawo ye-capillary kuhlobene eduze nendawo yokukhiqiza kanye nokuhlanzeka. Uma nje ipuleti le-convection, isithando somlilo kanye nodonga lwangaphakathi lwekhava yokuhlola kuhlanzwa ngesikhathi, ikhwalithi yangaphezulu ye-capillary yensimbi engagqwali ingathuthukiswa ngokungaqondile.
Lokhu okungenhla yisingeniso kwezinye izici ezithinta i-capillary yensimbi engagqwali engu-304. Enqubweni yokukhiqiza, ukunakwa okwengeziwe kufanele kukhokhwe kulokhu okuqukethwe ukuze kuqinisekiswe ukuthi imikhiqizo ekhiqizwayo ayinazo izinkinga ekusebenzeni nasekubukekeni.
