Shanghai Jiao Tong University tau ua tiav qhov kev nce qib tseem ceeb hauv kev ua haujlwm siab Drymom abrasive nplej lis nplej

"Xib fwb muab rau hauv pab pawg ntawm lub tsev kawm ntawv ntawm kev tsim khoom siv tshuab hluav taws xob, tau siv graphene kom sib haum pob zeb diamond abrasives, Lawv tau ua tiav qhov kev sib tsoo hauv kev ua yeeb yam ntawm lub cev ntawm kev ua yeeb yam ntawm kev ua yeeb yam ntawm cov neeg ua haujlwm "

 

Xib fwb shen bin pawg ntawm lub tsev kawm ntawv ntawm kev tsim tshuaj tshuab thiab khoom siv tsis siv neeg ua haujlwm hauv tsev kawm ntawv ntawm kev ua haujlwm tseem ceeb abrasives. Lawv tau luam tawm cov ntawv tshawb fawb "Lubalus ua yeeb yam coj tawm ntawm cov cuab yeej siv tshuab hluav taws xob" hauv phau ntawv xov xwm kev tsim khoom lag luam. Los ntawm kev siv graphene rau kev sib dhos pob zeb diamond abrasives, lawv tau ua tiav qhov kev ua tau zoo ntawm kev ua yeeb yam ntawm lub cev ntawm kev ua yeeb yam ntawm lub cev ua yeeb yam rau thawj zaug. Txoj kev tshawb no tau txhim kho cov hnav tsis kam thiab ua polishing kev daws teeb meem ntawm cov micro / nano hais raws li cov hlau ua kua hlau. Thawj tus kws sau ntawv ntawm daim ntawv yog postDoctoral tshawb fawb lin Qiang, tus sau tus sau yog xibfwb Shen Bin, thiab Shanghai Jiao Tong University yog qhov chaw sib txuas.

Lub cim tshiab ntawm cov ntaub ntawv semiconductor xws li pob zeb diamond thiab silicon muaj cov kev cia siab thov kev cia siab hauv lub zog ntawm cov khoom siv hluav taws xob siab. Txawm li cas los xij, cov ntaub ntawv no muaj ultra-siab hardness thiab hnav tsis kam, ua kom muaj kev nyuaj sib xws. Tsoos Diamond Abrasive hais tau txwv coj kev tiv thaiv zoo thiab ua rau nws tsis zoo ntawm kev ua haujlwm zoo rau cov khoom lag luam tshiab ntawm cov qauv tshiab ntawm cov semiconductors. Muab cov ultra-siab intrinsic lub zog thiab hauv-dav hlau hnav tsis kam ntawm pob zeb diamond allgive tau xav kom ua tiav cov kev sib tsoo ntxiv hauv kev ua tau zoo.

 

Raws li cov tswv yim theoretical no, pab neeg tshawb fawb hloov ua kua rau hauv situ, yog li kawm tau lub pob zeb diamond hauv cov pob zeb micro ntawm cov npoo ntawm pob zeb diamond Cov. Graphene npaj los ntawm cov txheej txheem no tau txuas nrog lub pob zeb diamond abrased "armor" nrog ultra-siab interrasive, tawg los ntawm cov teeb meem botteneck ntawm graphene tau nquag nquag thiab tsis ua tiav hauv kev siv tshuab, thiab txwv kev txhim kho kev txhim kho ntawm pob zeb diamond ntawm pob zeb diamond hnav tsis kam. Ib qho ntxiv, "ntawm cev ntawm cev" tshem tawm cov kev npaj ua kom zoo dua qub Cov.

Hauv kev siv cov tswv yim, piv nrog pob zeb diamond abrasive uas muaj, pob zeb muaj zog ntawm cov khoom siv sib txuas ntxiv (pob zeb diamond zoo nkauj (pob zeb diamond, silicon carbide, lwm yam). Lawv cov khoom tshem tawm cov khoom tshem tawm yog tsib zaug ntawm cov tsoos Diamond Abrasive, ua tau zoo tshaj qhov ua tau zoo ntawm lwm cov khoom muaj abrasive. Qhov kev ua tiav no tawg los ntawm kev ua tau zoo ntawm kev ua yeeb yam ntawm kev daws teeb meem thiab muab kev daws teeb meem tshiab rau kev ua tiav thiab tsis yog-kev puas tsuaj polishing ntawm suphard semiconductors. Ib qho ntxiv, cov khoom lag luam ntau tshaj plaws muaj cov kev cia siab ntawm cov khoom siv hluav taws xob, thiab kev ua haujlwm ntawm cov txheej txheem sib txuam zoo thiab cov kev tsim kho kom zoo los ntawm cov txheej txheem sib txawv, vim nws Cov npoo av tshwj xeeb thiab muaj zog zoo tshaj plaws.

Www.chinadiatools.com yog lub vev xaib tshaj lij rau pob zeb diamond cuab yeej hauv Suav teb. Tau txais cov ntaub ntawv tshiab, kev sab laj, cov lus hais, thiab cov chaw muag khoom ua si hauv Suav teb hauv Suav teb ntawm Tuam Tshoj Pob Ntsiam Hluav Taws Xob
