Iingenelo ezikhethekileyo zeGreen Silicon Carbide Micropowder kwizixhobo zokugquma
Ukuba wakha wasebenza ngezinto zoshishino, ngokuqinisekileyo uvile ngazoi-silicon carbide eluhlazaLe nto "yinati enzima kakhulu ukuyiqhekeza" kwihlabathi elirhabaxa, ilandela idayimani kunye ne-boron carbide ngobunzima, isetyenziselwa kakhulu ukugaya nokusika. Kodwa kusenokwenzeka ukuba awuzange ucinge ukuba xa yenziwe yaba ngumgubo ocolekileyo olingana ne-micron kwaye yongezwa kwizinto zokugquma, inokuba luncedo kakhulu, izise iziphumo ezininzi ezingalindelekanga nezimangalisayo. Namhlanje, masiyihlalutye size sixoxe ngeenzuzo zayo eziphambili kwicandelo lokugquma.
Inzuzo Yokuqala: Inzima! Inzima Ngenene!—Ukumelana Nokunxiba Okungenakuthelekiswa Nanto
Oku kuvela kwindalo yayo. I-silicon carbide eluhlaza iqinile ngokwemvelo; ukuyongeza kwiingubo kufana nokunika i-coating "ihempe yentsimbi." Cinga ngayo, yintoni eyoyikwa kakhulu ziingubo? Ukurhawuzelelwa. Umzekelo, umgangatho wefektri uhlala uhlaselwa kukugrutywa nokukrwelwa kweefolokhwe kunye nezihlangu ezinzima; oomatshini bokwemba bahlala besebenza ngentsimbi kunye nesanti.
Ngeli xesha, iingubo eziqhelekileyo zinokuguguleka ngokukhawuleza kwaye zixobuke, kodwa iingubo ezinee-microparticles ze-silicon carbide eziluhlaza ezongeziweyo zibonisa ubunzima obongezelelekileyo. Ezo nxalenye zangaphandle ezirhabaxa zizama ukukrazula umaleko wepeyinti? Uxolo, kuya kufuneka zidlule ezi microparticles zingenakubalwa, ezilukhuni kakhulu kuqala. Zisebenza njengee-"little shields" ezinzima ezingenakubalwa, zisasazwa ngokulinganayo kuyo yonke ingubo, zimelana ngokuthe ngqo nokuguguleka. Ke ngoko, naphi na apho kufuneka khona ukumelana nokuguguleka, njengemigangatho, imigca yokuhlanganisa, ii-silos, kunye nee-screw conveyors, ukuyisebenzisa kunokwandisa ubomi bengubo izihlandlo ezininzi, konge iindleko ezinkulu zokugcinwa kunye nokutshintshwa.
Inzuzo yesibini: Uzinzo oluqinileyo njengelitye—ukumelana nobushushu obuphezulu kunye nozinzo oluphezulu lobushushu
Le yinto ezinye izizalisi ezininzi ezingenakuyifanisa.Ikhabhayithi yesilicon eluhlazayenziwe kwisithando sombane esishushu kakhulu kwiqondo lobushushu obuphezulu kwiqondo lobushushu obungaphezulu kwama-2000 degrees Celsius, ngoko ke ayitshisi ngokwemvelo. Xa uyidibanisa neengubo ezishushu kakhulu, nokuba ubushushu obuphakathi bufikelela kuma-500-600 degrees Celsius nangaphezulu, ayitshintshi, igcina isakhiwo sizinzile kwaye ayiboli okanye inyibilike xa ifudunyezwa.
Ngokomzekelo, ezinye izinto zokuzalisa zifana nomkhenkce, zinyibilika xa kushushu kakhulu; ngelixa i-silicon carbide micropowder eluhlaza ifana nelitye, iba namandla xa kushushu. Olu phawu lwenza ukuba ifaneleke ngakumbi ukusetyenziswa kwiindawo ezinobushushu obuphezulu ezifana nemibhobho yokukhupha umoya yenjini, iibhoyila zemizi-mveliso, ii-heat exchangers, kunye neetshimini. Ukwaleka kuhlala kuzinzile ixesha elide, ngaphandle kokuqhekeka okanye ukudumba, kukhusela ngokuqinileyo i-substrate—inzuzo ebalulekileyo.
Inzuzo yesithathu: Ukubamba okugqwesileyo—ukunamathela okugqwesileyo kunye namandla okugquma
Oku kungabonakala kungqubana: amasuntswana athambileyo naqinileyo angayiphucula njani indlela anamathela ngayo? Imfihlo ikwimo yawo ye-engile kunye nokusasazwa okufanayo.
Phantsi kwe-microscope,i-micropowder eluhlaza ye-silicon carbideAyilo mbulunga ingqukuva ngokugqibeleleyo, kodwa yipoligoni enemiphetho ebukhali. Xa ixutywe ne-resin yokugquma, le miphetho ebukhali isebenza njengeenzipho ezincinci ezingenakubalwa, ibamba ngokuqinileyo i-substrate ngelixa ngaxeshanye isenza i-interlock eqinileyo yoomatshini kunye ne-resin matrix. Oku kufana nokuma phezu komkhenkce ogudileyo; izihlangu ezisicaba azizinzanga, kodwa izihlangu ezinezikhonkwane ezininzi esinqeni zinokungena ngokuqinileyo.
Ke ngoko, ii-coating ezisebenzisa le nto zihlala zixela ukuba zinamathelana kakhulu kwaye azikwazi ukuxobuka. Ngaphezu koko, iphucula kakhulu amandla apheleleyo kunye namandla okucinezelwa kwe-coating, okwenza ingabi buthathaka kwaye ingachaphazeleki lula.
Inzuzo yesine: Ukuqhuba kakuhle kombane kunye nobushushu - ukusebenza okungaqhelekanga
Ngaphandle "kokuzikhusela ngokomzimba" okukhankanyiweyo ngaphambili, ikwagqwesa "ekusebenzeni." I-silicon carbide eluhlaza inomlinganiselo othile wokuqhuba ubushushu. Ukuyifaka kwiingubo kunokuphucula isiphumo sokusasaza ubushushu. Umzekelo, xa isetyenziswa kwizixhobo ezifuna ukusasazeka kobushushu, ubushushu bunokuqhutywa ngokulinganayo, kuthintelwe ukushushubeza kwendawo.
Ngaphezu koko, ngokulawula ubungakanani bayo bokongeza kunye nobukhulu bamasuntswana, ukuhanjiswa kombane kwengubo kunokulungiswa ukuya kwinqanaba elithile. Oku kubaluleke kakhulu kwizicelo ezikhethekileyo ezifuna iipropati ezichasene nokuqina, ezifana nomgangatho we-epoxy kwiindawo zokusebenzela ze-elektroniki, njengoko kuthintela iingozi ezinxulumene nokwakheka kombane ongashukumiyo.
Inzuzo yesihlanu: Ukumkani wokusebenza kakuhle kweendleko – ongabizi kakhulu kwaye osebenzayo
Ukuthetha ngemali, iluncedo ngakumbi. Unokucinga ukuba imveliso enamandla kangaka ibiza kakhulu, akunjalo? Akunjalo konke konke. Xa ithelekiswa nezinye izinto ezikumgangatho ophezulu okanye izongezo ezikhethekileyo, i-green silicon carbide micropowder ngumzekelo obalaseleyo "womgangatho ophezulu ngexabiso eliphantsi."
Umthombo wayo uzinzile, inkqubo yayo yemveliso sele ivuthiwe, kwaye ixabiso layo lifikeleleka lula ngokwendalo. Nangona kunjalo, inkqubela phambili eyizisayougqubuthelo ukusebenza kuyinyani kwaye kuyakhawuleza. Ukuchitha imali encinci ukuze ufumane iziphumo ezintle, ukuphucula kakhulu ukusebenza kwemveliso ephambili ngexabiso eliphantsi - yeyiphi injineli okanye umphathi wokuthenga ongayithandiyo olu hlobo "lokusebenza kakuhle kweendleko"?
Emva kokuba sixoxe ngeengenelo zayo, masithethe ngendlela yokuyisebenzisa ngokufanelekileyo, nto leyo efuna ukuqwalaselwa:
Ukukhetha ubungakanani bamasuntswana kubalulekile: Kufuneka "ukhethe ubungakanani bamasuntswana obufanelekileyo kwimveliso efanelekileyo." Ukuze ufumane uboya obuthambileyo nobuthambileyo, khetha umgubo ocolekileyo (umz., F800 okanye ngaphezulu); ukuze ufumane uboya obutyebileyo apho umphezulu orhabaxa wamkelekile kwaye kufuneka uxhathise ukuguguleka okuphezulu, ubungakanani bamasuntswana obuphakathi ukuya koburhabaxa (umz., F180-F400) busebenza ngakumbi.
Ukusasazeka kubalulekile: le mpuphu "inenkani" kwaye idla ngokudibana. Kufuneka ufumane indlela yokuqinisekisa ukuba isasazeke ngokulinganayo kuyo yonke i-coating. Ukuba ayixutywanga ngokulinganayo kwaye yenza amaqhuma, iya kuba bubuthathaka kwi-coating. Ke ngoko, izixhobo ezifanelekileyo zokusasazeka kunye neenkqubo zibalulekile.
Ukuxubana okuvumelanayo kubalulekile: kufuneka "kuhambelane" ne-resin kunye nezongezo. Ukongezwa kwayo akufuneki kuchaphazele ezinye iimpawu zokwambathisa, ezinje ngokumelana nokugqwala okanye ukuguquguquka.
Kufuphi,i-micropowder eluhlaza ye-silicon carbideIfana nesixhobo esinamandla esiphantsi kwizinto zokugquma. Ayizibonisi, kodwa ixhasa ngokuthe cwaka ibhena yokumelana nokuguguleka ngenxa yobunzima bayo obuphezulu kakhulu, ikhusela ukusebenza kobushushu obuphezulu kunye nokuzinza kwayo kobushushu, kwaye iphucula "ukubamba" kwengubo ngeemiphetho zayo ezibukhali. Idibene nokusebenza kwayo okugqwesileyo kunye nokusebenza kakuhle kweendleko, ibe "sisixhobo" esibalulekileyo kwizixhobo zeenjineli xa ziyila iingubo zokusebenza eziphezulu.
Ngexesha elizayo xa udibana nomngeni wokugquma ofuna ukumelana nokuguguleka, ukumelana nobushushu obuphezulu, okanye amandla aphezulu, cinga ngale "ndoda ilukhuni" eluhlaza - i-green silicon carbide micropowder; isenokuba yimpendulo oyifunayo.
