Imisebenzi kanye Nokusetshenziswa kwe-Brown Corundum Micropowder Embonini Yezimbozo
Uma sikhuluma “ngabantu abanamandla” embonini yokugqoka,i-corundum micropowder ensundu Akungabazeki ukuthi yiyona engcono kakhulu. Ungakhohliswa ukubukeka kwayo okumnyama; iyinto eguquguqukayo futhi enekhono emhlabeni wezingubo zokumboza! Abenzi bopende abanolwazi bayazi ukuthi ukwengeza i-corundum micropowder ensundu kuyisihluthulelo sokufinyelela kokubili ukumelana nokuguguleka kanye nokuqina.
I-corundum micropowder ensundu imane nje iyizinhlayiya ezincane ezinobukhulu obufana nobe-microni-aluminium oxide okuqukethwe cishe okungu-95%. Kuhlungwa esithandweni sikagesi se-arc kusuka ezintweni zokusetshenziswa ezifana ne-bauxite ne-coke emazingeni okushisa angaphezu kuka-2,000 degrees Celsius. Inqubo ifana nokupheka: ukushisa okulungile kanye nebhalansi efanele yezithako kuphela okungakhiqiza umkhiqizo ongcono kakhulu. Ngobunzima be-Mohs obungu-9, obulandela idayimane kuphela, kubhekwa njengento enzima kakhulu embonini yokugqoka.
Ngikhumbula ngonyaka odlule lapho sivakashele imboni yokumboza phansi yezimboni, umphathi we-workshop wakhomba phansi elalisanda kuqedwa futhi waqhosha kithi, “Uyabona? Leli phansi lenziwe ngemboza efakweimpuphu ye-corundum ensundu. Ama-forklift agijima phezu kwayo nsuku zonke, futhi ayizange ngisho nokuyiklwebha eminyakeni engaphezu kwemithathu!” Kamuva, sezwa ukuthi uqweqwe lwawo luqukethe i-20% brown corundum powder engu-325-mesh brown, eye yandisa ukumelana kwayo nokuguguleka ngokuphindwe kathathu kunoqweqwe oluvamile.
Emkhakheni wezingubo zokulwa nokugqwala, i-brown corundum powder idlala indima ebalulekile. Imiphetho yayo ebukhali yakha isakhiwo sokusekela esizinzile ngaphakathi kwengubo, njenge-"skeleton" yengubo. Ngonyaka odlule, iphrojekthi yesikhulumi sasogwini yayidinga ingubo eyayimelana nokugqwala kwamanzi olwandle futhi ikwazi ukumelana nokungqubuzana kwemishini. Ifomula ephumelele yasebenzisa i-brown corundum powder ephathwe ngokukhethekile, futhi ngezwa ukuthi yahlala iminyaka emibili emanzini olwandle ngaphandle kokukhishwa kopende.
Isici esiyinselele kakhulu sobuchwepheshe yisilinganiso sempuphu ye-corundum ensundu efakwe ephepheni. Ubuningi kakhulu buzokwenza upende ube mkhulu kakhulu futhi kube nzima ukuwusebenzisa; ubuningi kakhulu buzokwenza ungasebenzi. Ingcweti enolwazi isebenzisa isifaniso esicacile: “Kufana nokuxova inhlama. Uma kunamanzi amaningi kakhulu, engeza ufulawa; uma kunofulawa omningi kakhulu, engeza amanzi. Kufanele uthole ibhalansi ephelele.” Ngokuvamile, umthamo usukela ku-15% kuya ku-30% kuye ngokuthi upende uhloselwe ukusetshenziswa kanjani. Isibonelo, upende waphansi ungasebenzisa okuningi, kanti upende wasolwandle udinga okuncane.
I-micropowder ye-corundum ensunduitholakala ngobukhulu obuhlukahlukene, kusukela ku-800 kuya ku-2000 mesh. Uma ine-mesh incane, imiphumela yayo ihlukile. Izinhlayiya eziqinile zisetshenziselwa izinhlelo zokusebenza ezingasheleli, kuyilapho izinhlayiya ezincane zifaneleka kakhulu kuma-topcoat. Umkhiqizi wengubo yezemidlalo wabelane ngolwazi lwakhe: basebenzisa i-240 mesh njengengubo eyisisekelo ukuze bathuthukise ukunamathela kanye ne-800 mesh yengubo ephezulu ukuze bathuthukise ukumelana nokuguguleka. Le nhlanganisela iveza imiphumela emihle ngokumangazayo.
Kodwa-ke, kumele kuthathwe izinyathelo zokuphepha ngesikhathi sokufaka. I-brown corundum micropowder inomsoco oqondile ophezulu futhi ithambekele ekuzinzeni, ngakho-ke kufanele kufakwe i-ejenti efanele yokulwa nokuqina ngesikhathi senqubo yokukhiqiza upende. Ukuxuba nakho kubalulekile, njengoba ukusatshalaliswa okungalingani kungathinta umphumela wokugcina. Imboni eyodwa yabhekana nalokhu kulahlekelwa. Ngenxa yokunganeli kwesikhathi sokuxuba, iqoqo lopende lalinokugcwala okungalingani phakathi kwamajazi aphezulu naphansi, okwaholela ekwehlukeni kombala ngemva kokufaka futhi kwadinga ukulungiswa kabusha.
Njengoba izidingo zokuvikela imvelo ziqhubeka ziqina, inqubo yokukhiqizaimpuphu ye-corundum ensunduithuthuka njalo. Abakhiqizi abaningi manje bakhuthaza imikhiqizo engenalo uthuli oluningi ukuze banciphise ukungcola kothuli ngesikhathi senqubo yokukhiqiza. Ezinye izinkampani zicwaninga nobuchwepheshe bokuguqulwa kwendawo ukuze zenze i-brown corundum powder ikwazi ukubopha kangcono nama-resin futhi ithuthukise ukusebenza okuphelele kokumbozwa.
Sekukonke, amathuba okusetshenziswa kwempuphu ye-corundum ensundu embonini yokugqoka maningi kakhulu. Kusukela phansi kuya emikhunjini, kusukela emapayipini kuya ematangini okugcina izinto, ingatholakala yonke indawo. Ngokuvela okuqhubekayo kwezinto ezintsha nezinqubo ezintsha, le "mpahla endala" nayo ithola amandla amasha.
Ngakho-ke, ngesikhathi esizayo lapho uhlangana nokusetshenziswa okudinga ungqimba olungagugi futhi oluhlala isikhathi eside, zama ukwengeza i-corundum powder ensundu. Mhlawumbe lolu shintsho oluncane lungakhuphula kakhulu ukusebenza komkhiqizo wakho! Phela, empeleni, amafomula amaningi asebenzayo atholakala ngokuzama namaphutha.
