IGreen Silicon Carbide Micropowder: Indlu Enamandla Yokuphucula Ukusebenza Kweengubo Zemizi-mveliso
Namhlanje, makhe sixoxe ngasese malunga nokuba yintoni eyenza le micropowder eluhlaza yesilicon carbide ibe yekhetheke kangaka.
I. Okokuqala, masicacelwe ukuba le "green silicon carbide" ithetha ukuthini.
Ukuva eli gama okokuqala, livakala ngathi “liyikhemikhali” kwaye liyiteknoloji ephezulu. Kodwa eneneni, lifana nomzala we-alumina emhlophe exutywe kakuhle esithethe ngayo ngaphambili—zombini zingamalungu osapho lwezinto eziqinileyo kakhulu.
Ukwenziwa kwayo kufana nokwenza intsimbi: izinto ezikrwada ezifana nesanti ye-quartz kunye ne-petroleum coke ziphoswa kwisithando sombane esimelana nokumelana kwaye "zicocwe" kumaqondo obushushu angaphezu kwama-2000 degrees Celsius. Ngenxa yokuba iqulethe izinto ezithile, ijika ibe ngumbala oluhlaza owahlukileyo, yiyo loo nto ibizwa ngokuba yi-"green silicon carbide."
Iimpawu zayo eziphambili ziphakathi kwamagama amabini: eqinileyo nebukhali.
Inzima kangakanani? Kwisikali seMohs, ifika kwi-9.2–9.5! Kuthetha ukuthini oko? Yesibini emva kwedayimani (10) kwaye idlula kakhulu iintsimbi eziqhelekileyo, iglasi, kunye nemarble ngobunzima. Ngaphezu koko, amasuntswana ayo ngokwendalo anemiphetho ebukhali kunye neekona, ngokungafaniyo nezinye izizalisi ezingqukuva ezigudileyo nezingqukuva.
Khawucinge ngayo njengeebhiliyoni zeefayile zedayimani ezincinci neziqinileyo. Kuthi kushishino lokufaka iingubo, ukuyongeza kwingubo kufana nokunika ingubo umaleko ongabonakaliyo “wezixhobo zokuzikhusela ngeposi.”
II. Ikwazi njani "ukutshaja kakhulu" iingubo?
Ukuzincoma nje ngobulukhuni bayo akunamsebenzi. Ixabiso layo lokwenyani lisekuphuculeni ukusebenza kokugquma—kulapho ke kwenzeka khona umlingo wokwenene.
Okokuqala nokubaluleke kakhulu—ubuchule bayo—kukumelana nokukrweleka nokukrweleka.
Kulula ukuyiqonda le nto. Khawuthelekelele umphezulu wakho wokugquma ugqunywe ngamasuntswana amaninzi aqinileyo, abukhali njengerazor. Xa into ethile ikrwela okanye iguba kuyo, la manqaku aqinileyo enza "umgca wokuqala wokuzikhusela." Amandla angaphandle kufuneka aqale awoyise ngaphambi kokuba afikelele kwisiseko seresin esithambileyo esingaphantsi.
Kufana nokuhamba phezu kodaka oluthambileyo—inyathelo ngalinye lishiya umkhondo onzulu. Kodwa kwindlela egalelwe ngamatye aqinileyo, awuzukushiya mkhondo. Uvavanyo lwethu lubonisa ukuba ii-epoxy floor coatings ezinefomula efanayo kodwa eziquka ubungakanani obufanelekileyo be-silicon carbide micropowder eluhlaza zinokuphinda kabini okanye kathathu ubomi bazo xa zivavanywa nge-abrasion tester! Kwiindawo ezifana neeworkshops zasefektri, iindawo zokupaka, kunye neendawo zokugcina impahla ezinkulu, le ntsebenzo ibaluleke kakhulu.
Inzuzo yesibini kukunamathela okuphuculweyo, okuvumela ukuba i-coating "ibambe" ngokuqinileyo.
Le nzuzo inokumangalisa abantu bangaphandle. La masuntswana e-micropowder awamane nje antante nje kuphela kwi-coating—akha isakhiwo se-"anchor chain" esincinci. Kwelinye icala, iindawo zawo ezirhabaxa zidibana ngokufanelekileyo ne-resin. Kwelinye icala, xa zisetyenziswa kwi-substrates ezifana nentsimbi okanye ikhonkrithi, la masuntswana aqinileyo angena kwi-microscopic errors, nto leyo eyenza amandla anamandla okudibanisa izinto.
Ngamafutshane: iingubo eziqhelekileyo zifana nokusebenzisa iglu ukuncamathisela iphepha eligudileyo eludongeni. Nangona kunjalo, iingubo ezine-silicon carbide eluhlaza zifana nokulungisa umphezulu wodonga kuqala, uze uzifake izikhonkwane ze-hook-and-loop. Inqanaba lokunamathela alinakuthelekiswa nanto. Oku kubalulekile ekuthinteleni ukuxobuka nokuqhekeka kwengubo.
Inzuzo yesithathu: Ukumelana nokutyibilika okuphuculweyo, ukubeka phambili ukhuseleko.
Nokuba ziimigangatho yefektri, iidekhi zeenqanawa, okanye iibhulorho zabahambi ngeenyawo, ukumelana nokutyibilika kubaluleke kakhulu. Amasuntswana e-silicon carbide micropowder aluhlaza asasazeka ngokulinganayo kumphezulu wokugquma, enza iiprotrusion ezincinci neziqinileyo ezikhulisa kakhulu uburhabaxa bomphezulu kwaye zonyusa ukulingana kokungqubana.
Abasebenzi abanxibe izihlangu zokhuseleko baziva bekhuselekile xa behamba ngazo; abahambi ngeenyawo ngemini yemvula abanakutyibilika lula. Isiqinisekiso sokhuseleko esibonelelwa koku asinakuthelekiswa nanto.
Okwesine, iyasebenza ngeendlela ezahlukeneyo, inika zombini ukumelana nobushushu kunye nokugqwala.
I-silicon carbide eluhlaza ngokwayo ineempawu zeekhemikhali ezizinzileyo kakhulu, imelana nee-asidi, ii-alkalis, i-oxidation, kwaye igqwesa kwiindawo ezinobushushu obuphezulu. Ukuyifaka kwiingubo kudlulisela ngempumelelo ezi "mpawu" zibalaseleyo. Kwizixhobo ezikwizityalo zeekhemikhali okanye kwiipayipi ezinobushushu obuphezulu, oku kuphakamisa ukuqina kwengubo ukuya kwinqanaba elitsha.
III. Kwanesixhobo Esilungileyo Sifuna Izakhono: Ubugcisa Bokusebenzisa
Kakade ke, isixhobo esibukhali sisebenza kakuhle kuphela xa umntu esisebenzisayo—awunakusiphatha nje ungacingi. Kukho umahluko omkhulu okhoyo.
Okokuqala, ukukhetha ubungakanani obufanelekileyo besuntswana bubuchule ngokwalo. Umgubo we-silicon carbide oluhlaza usukela kumakhulu ukuya kumawaka e-mesh. Ukuba usebenzisa i-grade erhabaxa kakhulu—masithi, i-100 mesh okanye ngaphezulu—umphezulu wokugquma uya kuvakala urhabaxa xa uwuchukumisa, nto leyo echaphazela ubuhle. Ngokwahlukileyo koko, ukusebenzisa i-grade erhabaxa kakhulu—njenge-3,000 ukuya kwi-5,000 mesh—ngokuyintloko kwandisa amandla kunye nobunzima kodwa kunciphisa ukutyibilika. Ke ngoko, ukukhetha kufuneka kuhambelane nenjongo yakho yokugqibela: kumgangatho, i-grade erhabaxa inokwanela; kwi-topcoats zoshishino eziphezulu, i-grade erhabaxa inokukhethwa ukuze kuphuculwe ukuxhathisa ukuguguleka ngaphandle kokubeka emngciphekweni i-leveling.
Okwesibini, ulawulo oluchanekileyo lobungakanani bokongeza lubalulekile. Okungaphezulu akuyonto ingcono kangako. La masuntswana anomxhuzulane ophezulu, kwaye ubuninzi obugqithisileyo bunokubangela ukuzola. Ukuba ugqubuthelo luhlala ixesha elide kakhulu, luya kwahluka—ioyile ecacileyo phezulu, ulwelo olusezantsi—luze lungabi namsebenzi. Ngaphezu koko, ukongeza okuninzi kakhulu kuchaphazela kakhulu ukulingana kunye nokukhazimla kogqubuthelo, okunokubangela isiphumo sexolo le-orenji elingathandekiyo kumphezulu otshiziweyo. Sihlala sifumana ibhalansi efanelekileyo phakathi kokusebenza, ukusebenza kakuhle, kunye neendleko ngokuvavanya okuphindaphindiweyo.
Okokugqibela, ukusasazwa kubaluleke kakhulu. La masuntswana mancinci abonisa amandla aqinileyo e-van der Waals, nto leyo ebangela ukuba ahlangane. Ukuba awasasazwanga kakuhle, enza amasuntswana ngaphakathi kwengubo. La masuntswana awaphumeleli nje kuphela ekuziseni iingenelo, kodwa adala neendawo zoxinzelelo ezinciphisa ukusebenza kwengubo. Ke ngoko, i-dispersant efanelekileyo kufuneka isetyenziswe kunye nezixhobo ze-dispersion ezinamandla aphezulu ukuqinisekisa ukuba yonke i-microparticle igqunywe kakuhle kwaye ngokulinganayo yi-resin slurry. Kuphela emva koko amandla ayo apheleleyo anokuphunyezwa.
