Green silicon carbide poda: chombo chakavanzika chekuvandudza kukwenenzvera kupenya
Kuma2:00 mangwanani, Lao Zhou anobva kumusangano wepanhare mbozha yekuseri akakanda chivharo chegirazi chaive chichangobva pamutsetse wekugadzira patafura yekuongorora, uye ruzha rwakanga rwakatsetseka sekudzima moto. "Tarisa! Ibhechi rechigumi! Pepa reOrenji nemhute. Vaongorori veApple vachasvika mangwana. Chinhu ichi chingaunzwa here?!" Ropa raiva mumaziso ake rakanga rakatsvuka kudarika indicator light remushini. Li, uyo akanga akanyarara ari mukona, zvishoma nezvishoma akasaidzira bhakiti reupfu hwakasvibirira hwakasvibirira pamusoro, “Edza uyu 'mupengo wegirini', ndiwo unonyanya kunakidza kukuya mapfupa akaomarara." Mazuva matatu gare gare, boka rekutanga rezvigadzirwa zvinokwanisa rakatakurwa nendege husiku. Lao Zhou akabhabhadzira bhaketi regreen powderuye akanyemwerera: “Murume mudiki uyu ane hasha anogona chaizvo kuponesa upenyu!” Munhandare yehondo yekupenya, inova nhangemutange nenguva.green silicon carbide poda (SiC)mushonga une simba uye unoshanda unonyatso kubata marudzi ese e "kusakwanisa kukuya" uye "kutadza kupukuta".
Green silicon carbide powder, inozivikanwa se "green carbon" kana "GC” munyika.white corundum cousin” uye yechipiri kubva kudhaimondi. Chinonyanya kushamisa "hembe dzayo dzegirinhi" - makristasi akachena esilicon carbide, ane mipendero yakapinza nemakona, uye anokurumidza uye anotyisa hasha.green silicon carbidei "demolition captain" akabata micro mace, nyanzvi yekutsenga mapfupa akaomarara, uye kushanda kwayo kunoshamisa.
Kukosha kwaro kuri mumweya "wekukurumidza, wakarurama, uye usina tsitsi":
1. Kutsenga "mapfupa akaoma": kunyanya mumhando dzose dzekusateerera
Girazi renharembozha (Corning Gorilla), girazi rewachi resafire, crystal silicon wafer imwe chete, ceramic substrate… Aya "mapurojekiti ekumeso" eindasitiri yemazuva ano akaoma uye haana kusimba kupfuura mamwe. Mabrasives akajairika haashande kana kutyora mipendero kana simba rakawandisa rikaiswa. Iyo yakapinza mipendero yegirini silicon carbide poda (senge isingaverengeki madiki machisel padanho remicroscopic), pamwe nekuomarara kwayo kwepamusoro, inobvumira "kucheka" pamusoro pezvakaoma uye brittle zvinhu zvine hutsinye uye zvakatsiga. Inogona kukurumidza kusvuura zvinhu, pachinzvimbo che "kurima" semamwe mabrasives kukonzeresa kukuvara kwakadzika. Kupukuta kavha yembozhanhare? Inogona kukurumidza kudzikamisa "makomo" pamusoro pegirazi pasina kubatanidza "mipata" iri padivi payo, ichipeta kaviri kugona zvakananga, uye orange peel mavara? Aihwa!
2. Kucheka "banga rinokurumidza": nguva imari
PaTFT-LCD liquid crystal panel yekugadzira mutsara, sekondi yega yega yekugadzika nekupukuta kweiyo hombe-saizi yegirazi substrate ine chekuita nekugadzira kugona. Iyo "kumhanya" kwegirini silicon carbide poda yakanyorwa mumajeni ayo. Zvimedu zvayo hazvina kuoma uye zvakapinza chete, asiwo zvinoshamisa kuzvirodza - zvimedu zvakagomara zvinozvipwanya nekumanikidzwa, zvichiburitsa mipendero mitsva yakapinza kuti varambe vachirwa! Kusiyana nemamwe mabrasives akapfava, anova "akapfava" paanenge achikuya, uye kugona kwawo kunodonha. Uku "kuzvivandudza" kukwanisa kunobvumira kuti ive sehove mumvura mumatanho akaoma uye epakati ekupenya, uye chiyero chekubvisa zvinhu panguva imwechete (MRR) iri mberi kwevakwikwidzi vayo. Mushure mephotovoltaic silicon wafer fekitori yakachinjirwa kuita green silicon carbide slurry ine chaiyo particle size, kushanda kwesilicon wafer edge kubviswa kwakawedzera ne35%, uye kugadzirwa kwemazuva ese kwemutsara mumwe kwakasvinwa nemazana ezvimedu - mumwaka wekumhanyisa yekuisa, iyi imari chaiyo!
3. "Zvakanaka" mukushata: chiyero chakapfava pakati pekubudirira uye kurongeka
Usafunge kuti “green madmenPahwindo resafire rinopenya, kusarudza saizi yechikamu chakakodzera (seW7, W5 kana kutonyatsonaka mushure mekugadzikwa zvakanaka) uye fomula yegreen silicon carbide micropowder inoratidza "yakatetepa pasi pekukasharara". Inogona kubvisa nemazvo makwara akadzika uye sub-surface kukuvara kwezvikamu zvakasiiwa neyakagadzika tambo yedhaimondi kuitira kupenya kwechokwadi kunotevera (sekushandisa silica sol) yakakosha. Pasina iyo kubvisa zvakanaka "kukuvadzwa kwakaoma", danho rinotora nguva yekupukuta richawedzerwa zvakanyanya, uye chiyero chegoho chichava chakaoma kuvimbisa iyo, “basa rakaisvonaka” rokunamatidza foil yendarama gare gare richava risina maturo.
4. Kutamba ne "mvura inokuya": kugadzikana ndiyo nzira yekugara
Green silicon carbide micropowder ine yakagadzikana makemikari ehupfumi (inert) uye haisi nyore kuita neanowanzo shandiswa-based-based or oil-based polishing fluids. Izvi zvinorevei? Iyo slurry ine kugadzikana kwakanaka uye haisi nyore kushata, kugadzirisa kana agglomerate! Pamutsetse wekupolisha ine yakakwira dhigirii ye automation, yakagadzikana slurry performance ndiyo yehupenyu. Funga nezvazvo, kana iyo abrasive dzimwe nguva yakakora uye dzimwe nguva yakatetepa, uye zvimedu zvichibatana kuti zvivhare pombi, goho negadziriso yemidziyo ichashata zvakadii? “Green Carbon"Inoita kuti vanhu vasanetseke." Slurry yakagadzirwa inogona kufamba zvakanaka kana kureba, ichideredza zvakanyanya kuwanda kwekuvharwa kugadzirisa ma paramita uye mapombi akachena." Lao Wu, maneja wekugadzira fekitori inotakura zvinhu zveceramic, akataura nemanzwiro: "Sezvo yakagadzika girini yesilicon carbide slurry yakashandurwa, ndinokwanisa kugara pasi uye kunwa tii tichitarisa husiku. Zvaimboita sokudzima moto!”
Munguva ino yekutsvaga kupfava uye kushanda nesimba,green silicon carbide micropowderyakashandisa "chisimba chehasha" simba rayo rakaoma kuveza zita rayo rinoshanda uye rinovimbika kuseri kwechionioni chisingaverengeki chakafanana-hachisi basa rakapfava, asi rakanyatsokodzera "chombo chakavanzika" chekuvandudza kukwenenzvera.
