Amanqaku Abuhlungu Okupholisha Isikhunta
Nabani na osebenze kwishishini lokubumba iminyaka engaphezu kweshumi uyazi ukuba nangona ukupolisha kubonakala kulula, eneneni kuyinkimbinkimbi kakhulu. Abavelisi abaninzi bokubumba bafumana inkqubo yokupolisha yeyona inzima kakhulu - ithatha ixesha, iziphumo azingqinelani, kwaye ixhomekeke kakhulu kumava ochwepheshe. Oku kuyinyani ngakumbi ngoku, ngenxa yokwanda kokwahluka kwezinto zokubumba, ukusuka kwintsimbi yendabuko ye-P20 ukuya kwi-S136 eqinileyo, kwane-carbide eqinisiweyo kunye nezinto ze-ceramic. Izixhobo zokupolisha zendabuko kunye neenkqubo zihlala zingaphumeleli. Umphathi weworkshop yokupolisha yefektri yokubumba echanekileyo eShenzhen undixelele, “Ngaphambili, besisebenzisa i-boron carbide kunye ne-diamond powder, eyayisebenza kakuhle, kodwa ixabiso laliphezulu kakhulu; iifektri ezincinci ezininzi bezingenakukwazi ukuyihlawula. I-corundum powder eqhelekileyo idla ngokukrweleka, kwaye ngamanye amaxesha, emva kokupolisha, phantsi kweemeko ezithile zokukhanya, kusekho amabala amnyama.”
"Iimpawu Ezibalaseleyo" zeWhite Fused Alumina Micro-powder
Isizathuumgubo omncinci we-alumina emhlophe exutyiweyoIsebenza kakuhle kakhulu ekupolisheni isikhunta ixhomekeke "kwimo yayo yemfuza." Icandelo layo eliphambili yi-α-aluminium oxide, enobumsulwa obungaphezulu kwama-99%. Ithetha ukuthini le nto icocekileyo? Ithetha ukungcola okuncinci, okwenza kube lula ukubangela imikrwelo ngengozi ngexesha lenkqubo yokupolisha. Kufana nokugquma umthi ngephepha elincinci lesanti; ukuba iphepha lesanti lineenkozo ezimbalwa ezirhabaxa, umphezulu uya konakala. Enye inzuzo yokucoceka okuphezulu bubulukhuni obufanayo. I-alumina emhlophe exutywe kakuhle inobulukhuni be-Mohs obuyi-9.0, ilandela idayimani kunye ne-silicon carbide kuphela, kodwa inzuzo yayo ikukuhambelana kobulukhuni bayo. Abo bapolishayo bayaqonda ukuba ukuba amasuntswana arhabaxa anobulukhuni obungaguquguqukiyo, amasuntswana athambileyo ayadliwa kuqala, kwaye amasuntswana aqinileyo aphuma, nto leyo ebangela imikrwelo ngokulula. I-alumina emhlophe exutywe kakuhle i-micro-powder isebenza "ngokufanayo" kule nkalo.
Ubuchule beMofology yeeNgcambu
Kunyaka ophelileyo, ndityelele isityalo sokuvelisa umgubo we-alumina oxutywe ngombala omhlophe eJiangsu, kwaye umphathi wezobugcisa wandibonisa umfanekiso wokuthelekisa phantsi kwe-electron microscope: “Khangela, le yiumgubo omncinci we-alumina emhlophe exutyiweyo sivelisa; amasuntswana amaninzi anesikwere okanye aphantse abe yingqukuva, kwaye imiphetho iphathwe ngokukodwa ukuba ibe yingqukuva. Kwelinye icala, i-alumina micro-powder eqhelekileyo exutywe ngombala omdaka, ineemilo ezingaqhelekanga kunye nemiphetho ebukhali.” Lo mahluko ubalulekile ekupolisheni isikhunta. Nangona imiphetho ebukhali inika amandla okusika aqinileyo, inokubangela imikrwelo; amasuntswana angqukuva, kwelinye icala, asebenza ngakumbi “njengokuqengqeleka nokusila” kunokuba “anqumle,” nto leyo eyenza ukuba afaneleke ngakumbi ekupolisheni isikhunta esifuna ukugqitywa okuphezulu kakhulu komphezulu. Iingenelo zamasuntswana angqukuva zibonakala ngakumbi xa kupolishwa iindawo ezinzima ukufikelela kuzo ezifana nemiphezulu egobileyo kunye neekona zangaphakathi.
