Umehluko Omkhulu Phakathi kwe-Alumina Ehlanganisiwe Emhlophe neNsundu

Ukuqhumisa i-sandblasting kuyindlela yokwelapha ubuso evame ukusetshenziswa esebenzisa i-jet esheshayo yezinhlayiya ezihuzukayo ukuze kuhlungwe ubuso bento yokusebenza, kufezwe imiphumela yokuhlanza, ukupholisha, noma yokuhlobisa. Ukukhetha ukuqhumisa kuthinta ngqo ukusebenza kahle kanye nokusebenza kahle kokuqhumisa i-sandblasting. Phakathi kwama-abrasives amaningi, i-alumina ensundu nemhlophe ehlanganisiwe isetshenziswa kabanzi ngenxa yobunzima bayo obuphezulu kanye nokumelana okuhle nokuguguleka. Ukuqonda umehluko wokusebenza phakathi kwalokhu okubili kubalulekile ekwenzeni ngcono izinqubo zokuqhumisa i-sandblasting.

I. I-Alumina Ehlanganisiwe Ensundu Nemhlophe

Kokubili i-alumina ensundu nemhlophe ehlanganisiwe kuyizinhlobo ze-corundum, eyakhiwa kakhulu i-aluminium oxide. Umehluko usekwakhekeni kwayo: i-alumina ensundu ehlanganisiwe inensimbi, okwenza ibe nombala onsundu, kuyilapho i-alumina emhlophe ehlanganisiwe imhlophe qwa futhi ingenazo izinto ezingcolile. Ngenxa yokungcola okuku-alumina ensundu ehlanganisiwe, ubulukhuni bayo kanye nobuningi bayo kuphansi kancane kune-alumina emhlophe ehlanganisiwe.

II. Umehluko Omkhulu Phakathi kwe-Alumina Ehlanganisiwe Ensundu Nemhlophe

1. Ngokuphathelene nokuqina nobuningi, i-alumina emhlophe ehlanganisiwe ingcono kakhulu kune-alumina ensundu ehlanganisiwe. Ngenxa yokungcola, i-alumina ensundu ehlanganisiwe inobunzima nobukhulu obuphansi kancane kune-alumina ensundu ehlanganisiwe. Lo mehluko uthinta ngqo ukumelana kwayo nokuguguleka nokusebenza kokucubungula ekusetshenzisweni okugugulekayo. I-alumina emhlophe ehlanganisiwe inobunzima obukhulu nokumelana nokuguguleka okuqinile, igcina isimo esibukhali sezinhlayiya ezigugulekayo, ngaleyo ndlela ifinyelele ukunemba okuphezulu nokushelela ekuqhumeni kwesihlabathi, ekugayeni, nasekusebenzeni kahle. Ngokuphambene nalokho, yize i-alumina ensundu ehlanganisiwe inobunzima obuphansi kancane, isakhiwo sayo sekristalu esizinzile senza ingaphuki kalula, okwenza ifaneleke ekusetshenzisweni komshini onzima omelana nomthelela omkhulu.

2. Umehluko Ekusetshenzisweni Kwezimboni. I-alumina emhlophe ehlanganisiwe, ngenxa yokuqina kwayo okuphezulu kanye nokumelana nokuguguleka, ivame ukusetshenziswa ekucubungulweni kobuso obuhle, ukupholisha insimbi, kanye nokuqopha ngokunemba okuphezulu, okukhiqiza ukuthungwa okuhle nokubushelelezi. I-alumina ensundu ehlanganisiwe, ngenxa yokuqina kwayo okuphansi kancane kanye nokuguguleka okusheshayo, kodwa ukumelana okunamandla komthelela, ivame ukusetshenziswa ekuhlobiseni izakhiwo, ekuqopheni nasekuqhumeni kwesihlabathi okuqinile kwezinto ezinkulu zokusebenza. Ngaphezu kwalokho, izici zokucubungula ze-alumina ensundu ehlanganisiwe zakha kalula ukuthungwa kwe-capillary, okufanelekela ukufeza imiphumela ethile yokuhlobisa.

III. Isifinyezo

Ekuphetheni, i-alumina emhlophe ehlanganisiwe kanye ne-alumina ensundu ehlanganisiwe zihluka kakhulu ekwakhiweni kwamakhemikhali, umbala, ubulukhuni, ubuningi, kanye nokusebenza kokucubungula. I-alumina emhlophe ehlanganisiwe ifanelekela ukucubungula kahle kanye nokwelashwa kobuso obudinga kakhulu, kuyilapho i-alumina ensundu ehlanganisiwe isebenza kangcono ekusetshenzisweni okudinga ukumelana nokushayisana kanye nokucubungula okungafanele. Ukukhetha okulungile ngokusekelwe ezidingweni ezahlukene zokucubungula kungathuthukisa ngempumelelo ukusebenza kahle kokucubungula kanye nekhwalithi yobuso, kufezwe ibhalansi phakathi komnotho kanye nokusebenza kahle.

Ukuze uthole imininingwane eyengeziwe, sicela ukhululeke ukuxhumana nathi.
