Imisebenzi kunye nokusetyenziswa kweBrown Corundum Micropowder kwiShishini leeCoatings
Ukuthetha “ngabantu abanzima” kushishino lokufaka iingubo,umgubo omncinci we-corundum micropowder ngokuqinisekileyo yeyona iphambili. Musa ukukhohliswa yimbonakalo yayo emnyama; yinto eguquguqukayo nekwaziyo ukunxiba kwihlabathi leengubo! Abenzi bopende abanamava bayazi ukuba ukongeza i-brown corundum micropowder ngundoqo ekufikeleleni kokubini ekuchaseni nasekuqineni.
Umgubo we-corundum omdaka yi-particles nje ngobukhulu be-micron ene-i-aluminium oxide umxholo wayo omalunga ne-95%. Icociwe kwisithando sombane se-arc esenziwe ngezinto eziluhlaza ezifana ne-bauxite kunye ne-coke kumaqondo obushushu angaphezulu kwe-2,000 degrees Celsius. Le nkqubo ifana nokupheka: kuphela ubushushu obufanelekileyo kunye nokulinganisela okufanelekileyo kwezithako okunokuvelisa imveliso engcono. Ngobunzima be-Mohs obuyi-9, obulandela idayimani kuphela, ithathwa njengeyona nto inzima kakhulu kushishino lwezogqumo.
Ndikhumbula kunyaka ophelileyo xa sasityelele umzi-mveliso wokugquma umgangatho wemizi-mveliso, umphathi weworkshop wakhomba umgangatho osandul’ ukugqitywa waza waqhayisa ngathi, “Uyabona? Lo mgangatho wenziwe ngogquma olufakweumgubo we-corundum omdaka. Iiforklift zisebenza phezu kwayo yonke imihla, kwaye ayizange iyikrwele kangangeminyaka engaphezu kwemithathu!” Kamva, safumanisa ukuba uboya bazo bune-20% ye-325-mesh brown corundum powder, eyonyuse ukumelana kwayo nokuguguleka ngokuphindwe kathathu kuneengubo eziqhelekileyo.
Kwicandelo leengubo ezichasene nokugqwala, umgubo we-corundum omdaka udlala indima ebalulekileyo. Imiphetho yawo ebukhali yenza isakhiwo esixhasayo esizinzileyo ngaphakathi kwengubo, njenge "skeleton" yengubo. Kunyaka ophelileyo, iprojekthi yeqonga elingaselunxwemeni yayifuna ingubo eyayingamelani nokugqwala kwamanzi olwandle kwaye ikwazi ukumelana nokungqubana kwezixhobo. Ifomyula ephumeleleyo yasebenzisa umgubo we-corundum omdaka ophathwe ngokukodwa, kwaye ndeva ukuba yahlala iminyaka emibini emanzini olwandle ngaphandle kokukrazulwa kwepeyinti.
Eyona nto inzima kakhulu kwitekhnoloji ngumlinganiselo womgubo we-corundum omdaka ofakwe kwi-coating. Ukuba ininzi kakhulu iya kwenza ipeyinti ibe nkulu kakhulu kwaye kube nzima ukuyisebenzisa; ukuba incinci kakhulu iya kuyenza ingasebenzi. Ingcibi enamava isebenzisa umzekelo ocacileyo: “Kufana nokuxova intlama. Ukuba kukho amanzi amaninzi, yongeza umgubo; ukuba kukho umgubo omninzi, yongeza amanzi. Kuya kufuneka ufumane ibhalansi egqibeleleyo.” Ngokubanzi, umthamo uphakathi kwe-15% ukuya kwi-30% kuxhomekeke kwindlela ipeyinti esetyenziselwa ngayo. Umzekelo, iipeyinti zomgangatho zingasebenzisa ngaphezulu, ngelixa iipeyinti zasemanzini zifuna ngaphantsi.
Umgubo omncinci we-corundum micropowderifumaneka ngobukhulu obahlukeneyo, ukusuka kwi-800 ukuya kwi-2000 mesh. Okukhona i-mesh incinci, kokukhona iziphumo zahlukile. Amasuntswana aqinileyo asetyenziselwa usetyenziso oluchasene nokutyibilika, ngelixa amasuntswana ancinci afaneleka ngakumbi kwii-topcoats. Umenzi wengubo yebala lemidlalo wabelane ngamava akhe: basebenzisa i-240 mesh kwi-base coat ukuphucula ukunamathela kunye ne-800 mesh kwi-topcoat ukuphucula ukumelana nokuguguleka. Olu dibaniso luvelisa iziphumo ezilungileyo ngokumangalisayo.
Nangona kunjalo, kufuneka kuthathwe amanyathelo okhuseleko ngexesha lokufaka. I-brown corundum micropowder inomxhuzulane ophezulu kwaye ithambekele ekuzinzeni, ngoko ke kufuneka kongezwe i-arhente efanelekileyo yokulwa nokuqina ngexesha lenkqubo yokuvelisa ipeyinti. Ukuxuba nako kubalulekile, njengoko ukusasazwa okungalinganiyo kunokuchaphazela umphumo wokugqibela. Omnye umzi-mveliso wafumana le lahleko. Ngenxa yexesha elaneleyo lokuxuba, iqela lepeyinti lalinoxinzelelo olungahambelaniyo phakathi kwemibala ephezulu nesezantsi, nto leyo eyabangela umahluko wemibala emva kokufaka kwaye kwakufuneka kuphinde kusetyenzwe.
Ngenxa yeemfuno ezingqongqo zokhuseleko lokusingqongileyo, inkqubo yokuvelisaumgubo we-corundum omdakaiphucuka rhoqo. Abavelisi abaninzi ngoku bakhuthaza iimveliso ezinothuli oluphantsi ukunciphisa ungcoliseko lothuli ngexesha lenkqubo yemveliso. Ezinye iinkampani zikwaphanda ubuchwepheshe bokuguqula umphezulu ukuze kuvumeleke ukuba umgubo we-corundum omdaka unamathele ngcono kwiiresini kwaye uphucule ukusebenza ngokubanzi kweengubo.
Lilonke, amathuba okusetyenziswa komgubo we-corundum omdaka kwishishini lokugquma makhulu. Ukususela kumgangatho ukuya kwiinqanawa, ukusuka kwimibhobho ukuya kwiitanki zokugcina, inokufumaneka kuyo yonke indawo. Ngokuvela okuqhubekayo kwezinto ezintsha kunye neenkqubo ezintsha, le "zinto ezindala" ikwafumana amandla amatsha.
Ngoko ke, kwixesha elizayo xa udibana nesicelo esifuna upende oluqinileyo noluhlala ixesha elide, zama ukongeza umgubo we-corundum omdaka. Mhlawumbi olu tshintsho luncinci lunokunyusa kakhulu ukusebenza kwemveliso yakho! Kaloku, ekusebenzeni, iifomyula ezininzi ezisebenzayo zifunyanwa ngokuzama nokwenza iimpazamo.
