Ungase ungakholwa, kodwa ngesonto eledlule lapho ngivakashela iklayenti elidala elicubungula insimbi, ngezwa umsindo "wokuhogela" ovala izindlebe ngokushesha nje lapho ngingena eshabhu. Lapho ngibhekisisa kahle, izisebenzi eziningana zazisebenza ngezibhamu zokuqhuma kwesihlabathi, izinhlansi zindiza njengoba izinto ezihudulayo zishaya izingxenye zensimbi. Umphathi, u-Old Li, wangibona wanikina ikhanda lakhe, ekhomba isikhwama se-alumina abrasive ensundu ehlanganisiwe phansi: “Le nto iyinkinga enkulu ukuyisebenzisa. Idala uthuli oluningi, futhi ukuguguleka kuyashesha. Izisebenzi azithandi ukwenza lo msebenzi.”
Ngahlala phansi, ngathatha isandla samii-alumina emhlophe ehlanganisiweisampula esiyilethile, sayibeka esandleni sakhe: “Zama lokhu?” Ezinsukwini ezintathu kamuva, u-Old Li wangishayela ucingo: “Kuyini inkinga nge-white fused alumina sandblasting yakho? Akukhona nje kuphela ukuthi ukusebenza kahle kuphezulu, kodwa nokubonakala endaweni yokusebenzela kungcono kakhulu!” Empeleni, embonini yokwelapha ubuso, ukukhetha i-sandblasting efanele kufana nompheki okhetha ummese ofanele – kwenza umehluko omkhulu. Namuhla, ake sixoxe nge-white fused alumina sandblasting, izinzuzo zayo ezivelele, nokuthi ingasetshenziswa kanjani ngezindlela ongase uzilindele futhi ongase ungazilindele.
I. Ake sixoxe ngezinto ngokwazo: I-White Fused Alumina
Kalula nje, i-alumina emhlophe ehlanganisiwe iyinto ekhiqizwa ngokuncibilikisa nokuphinda ifake i-bauxite esezingeni eliphezulu esithandweni sikagesi se-arc emazingeni okushisa angaphezu kuka-2000°C. Ingxenye yayo eyinhloko yi-α-alumina, enokuhlanzeka okungaphezu kuka-99%. Kukhona isisho esidala embonini yethu esithi: “I-alumina emhlophe ehlanganisiwe, i-nut enzima ukuyiqhekeza,” ebhekisela ebulukhunini bayo be-Mohs obungu-9.0, obulandela idayimane kuphela. Lokhu kuhlanzeka okuphezulu nokuqina kwenza kube yinto efanelekile “yemisebenzi enzima” njengokuqhuma kwesihlabathi.
Abakhiqizi abaningi engihlangane nabo ekuqaleni babecabanga ukuthi ukuqhuma kwesihlabathi kuyafana, kungakhathaliseki ukuthi kuyini ukuklwebheka.
