Green Silicon Carbide Micropowder: Nyeredzi Inokurumidza YemaAbrasives Anoshanda Zvakanyanya
Nhasi, ngatirambei tichikurukura nezvemumwe mutambi ane simba mumhuri ine hasha—upfu hwegirini hwesilicon carbide. Isu tiri muindasitiri iyi tinoitumidza kuti "Hulk," uye hatifungi kuti zita racho rakasiyana; kugona kwayo kunoenderana nezita iroro. Munguva pfupi yapfuura takakurukura nezve alumina chena yakanyatsosanganiswa; yakaita semhizha yedare ine hungwaru, ichigadzira basa rakanaka uye rakachena. Asi "Hulk" yanhasi yakafanana nemukuru wemauto anotungamira muhondo, anonyanya kurwa hondo dzakaoma uye achigadzirisa matambudziko akaomarara. Sei ichinzi "nyeredzi iri kumuka"? Chikonzero chekutanga "kuoma kwayo."
Carbide yegirini yesilicon ine kuoma kwakanyanya pakati pezvinhu zvakajairwa zvekubvoora, ine kuomarara kweMohs kwe9.5, kushoma pane dhaimani. Usarerutsa musiyano uyu we0.5 pamusoroalumina chena yakasanganiswa; kana uchishanda nezvimwe zvinhu zvakaoma zvikuru, zvinoita mutsauko mukuru. Zvinhu zvitsva zviri kubuda nguva dzose: silicon carbide ceramics, aruminiyamu nitride, sapphire glass, photovoltaic silicon wafers, cemented carbide—imwe neimwe yakaoma kupfuura yekare. Kushandisa abrasives zvakajairika kwakafanana nekukwenya dombo nesimbi—kunonetsa uye hakushandi.
Asi ne green silicon carbide micropowder, zvakanaka chaizvo. Micheto yayo yakajeka, yakapinza inoshanda sezvishandiso zvidiki zvekucheka dhaimani, ichinyatso "tsenga" zvinhu izvi zvakaoma. Kunyanya muindasitiri ye photovoltaic, ichicheka simbi dzakaoma uye dzakapfava dze monocrystalline ne polycrystalline silicon ingots, uchaona kuti inoshandiswa muzvikamu zvakawanda zvemitsetse yekugadzira. Pasina iyo, mitengo nekubudirira kwekugadzira hazvingaderedzi. Izvi ndizvo zvamunodaidza kuti "chinhu chimwe chinokunda chimwe."
Uyezve, kupisa kwayo kunofambisa zvakanaka kwazvo.
Chinhu ichi pachacho chinofambisa kupisa zvakanaka. Izvi zvinobatsira zvikuru mukukuya. Fungidzira, kukuya nekukurumidza kunounza kupisa kukuru ipapo ipapo. Kana kupisa uku kukasagona kupera uye kukabatirira mukati mechinhu chebasa, zvinosuwisa: pamusoro pechinhu chebasa pane mukana we "kutsva" nekutsemuka; zvikamu zvesimbi zvinogona kupwanyika, zvichichinja kuoma kwazvo; uye saizi yezvikamu zvakanyatsonaka inogona kusanyatsojeka nekuda kwekuwedzera kwekupisa nekudzikama.
Upfu hwe silicon carbide yegirini hunoshanda se "system diki yekupisa," inokurumidza kuendesa kupisa kure nenzvimbo yekukuya, zvichideredza tembiricha yenzvimbo yekugadzirisa. Izvi zvinoderedza kukuvara kwebasa kunokonzerwa nekupisa zvakanyanya, zvichiita kuti kugadzirwa kuve kwakanaka. Ichi chinhu chakakosha, kunyanya kune zvinhu nezvikamu zvinonzwa kupisa zvakanyanya.
Uyezve, hunhu hwayo hwe "kuzvirodza" hunoita kuti basa rirambe rakapinza nguva dzose.
Mishonga yakanaka yekubvoora haisi chinhu chinoitwa kamwe chete; inofanira kugara kwenguva refu.zvidimbu zvegirini zvesilicon carbidedzakaoma uye dzakapfava, kana dzikaitwa nesimba rekukuya, zvidimbu zvakapfava zvinoputsika, zvichiratidza mipendero mitsva yakapinza kuti irambe ichishanda. Hunhu uhwu hunonzi "kuzvirodza."
Izvi zvakafanana nekushandisa penzura yemuchina; kana yave kusviba, unoidzvanya zvakare, uye penzura itsva inobuda kuti irambe ichidhirowa. Izvi zvinoreva kuti mukati mekugadzirisa kwese, kugona kwayo kucheka kunoramba kuri kutsva uye kwakasimba, pasina kusviba nekufamba kwenguva. Kushanda zvakanaka kwekugadzira kwakagadzikana, uye kunaka kwechinhu chebasa kwakafanana, zvichidzivirira mamiriro ezvinhu apo kunaka kunovandudza pakutanga asi kunozoderera gare gare. Izvi zvakakosha pakugadzirwa kwemazuva ano, kwakakura, uye kwega.
Regai ndikuudzei nyaya yechokwadi.
Gore rapera, fekitari inogadzira ma nozzles einjini anoshanda zvakanyanya yakandibata. Ma nozzles avo akagadzirwa neceramics dzakakosha dzine kuoma kwakanyanya. Kushandisa ma abrasives akajairwa pakugadzirisa kwaive kusingashande zvakanaka uye kuchidhura, kana kuti kunaka kwenzvimbo kwaive kusiri kwemhando yepamusoro, kazhinji kuchiratidza kutsemuka kudiki. Gare gare, vakaedza kushandisa green silicon carbide micropowder pakukuya nekupukuta zvakanaka, uye mhedzisiro yacho yakakurumidza. Kushanda zvakanaka hakuna kungowedzera ne30-40% chete, asi chinonyanya kukosha, pasi pe microscope, kukuvara kwepamusoro penzvimbo yebasa kwaive kusingaonekwe, uye mwero wegoho wakakwira zvakanyanya. Mukuru wavo akazochema-chema achiti, "Zvinoita sekuti basa racho rakanga risina kuoma; hatina kungosarudza michina chaiyo."
Unoona, ndiro simba re "Hulk"—muchikamu chayo chehunyanzvi, inogona kugadzirisa matambudziko asingagonekwe nevamwe.
Ehe, iyi "vanguard general" haina hunhu hwayo. Kunyange zvazvo yakaoma, kusimba kwayo kwakaderera, zvichiita kuti iome. Saka, kana ichishanda nezvimwe zvinhu zvakasimba, zvakaita sesimbi, inogona kusashanda zvakanaka seye alumina chena yakasimba. Uyezve, ruvara rwayo rwegirini rweemerald runobva mukusachena kushoma; mune mamwe maitiro ekupukuta e semiconductor anoda kuchena kwakanyanya kwemakemikari, kunyangwe zvinhu zvakachena zvinogona kudiwa. Asi izvi hazvideredzi chinzvimbo chayo chikuru mukugadzirisa zvinhu zvakaoma uye zvisina kusimba.
Saka sei ichionekwa se "nyeredzi iri kusimuka"? Ingotarisa mafambiro eindasitiri aripo iye zvino uye emangwana: ma semiconductor echizvarwa chechitatu (kabhidhi yesilicon, gallium nitride), simba idzva remagetsi, zviumbwa zvemuchadenga, magirazi emagetsi epamusoro… mazhinji emaindasitiri aya ezuva anovimba nezvinhu zvekugadzirisa zvinhu zvakaoma uye zvinopfava. Green silicon carbide micropowder ndeimwe yezvishandiso zvakakodzera uye zvinoshanda pakugadzirisa matambudziko aya akaoma.
Kugona kwayo kukura pamwe chete nemaindasitiri aya epamusoro-soro. Chero bedzi maindasitiri aya achikura, pachava nekudiwa kunoramba kuripo kweupfu hwe silicon carbide green hunoshanda zvakanyanya. Indasitiri yedu yekukwesha iri kuramba ichiongorora maitiro ekuita kuti zvidimbu zvayo zvienzane uye kugadziriswa kwayo pamusoro kuve nani, kuitira kuti ipenye zvakanyanya munguva ino ine tariro.
