Polishing thiab sib tsoo Properties ntawm Nano Silicon Carbide
Nano Silicon carbide hmoov(HW-D507) yog tsim los ntawm smelting quartz xuab zeb, roj av coke (los yog thee coke), thiab ntoo chips raws li raw cov ntaub ntawv los ntawm kub kub nyob rau hauv lub furnaces kuj. Silicon carbide kuj tseem muaj nyob rau hauv cov xwm txheej uas tsis tshua muaj cov ntxhia - hu ua moissanite. Nyob rau hauv high technology refractory raw cov ntaub ntawv xws li C, N, B thiab lwm yam uas tsis yog-oxide, silicon carbide yog siv dav thiab pheej yig tshaj.
β-SiC hmoovmuaj zog xws li tshuaj lom neeg ruaj khov, siab hardness, siab thermal conductivity, tsis tshua muaj thermal expansion coefficient thiab lwm yam. Yog li ntawd, nws muaj kev ua tau zoo heev xws li tiv thaiv kev puas tsuaj, kub tsis kam thiab thermal shock kuj. Silicon carbide tuaj yeem ua rau hauv cov hmoov abrasive lossis sib tsoo taub hau rau kev sib tsoo thiab polishing ntawm cov khoom xws li hlau, ceramics, iav thiab yas. Piv nrog rau cov khoom siv abrasive ib txwm, SiC muaj qhov hnav tsis kam, hardness thiab thermal stability, uas tuaj yeem txhim kho kev ua haujlwm raug thiab ua haujlwm zoo. Tsis tas li ntawd, nws muaj cov tshuaj tiv thaiv zoo heev thiab kub-kub stability, yog li nws muaj ntau yam ntawm daim ntawv thov kev cia siab nyob rau hauv ntau yam teb.
SiC tuaj yeem siv los npaj cov ntaub ntawv polishing, uas muaj ntau yam kev siv hauv tshuab engineering, hluav taws xob, khoom siv kho qhov muag thiab lwm yam. Cov khoom siv polishing no muaj cov khoom zoo heev xws li siab tawv, hnav tsis kam thiab tshuaj lom neeg ruaj khov, uas tuaj yeem ua tiav cov haujlwm zoo polishing thiab sib tsoo. Tam sim no, lub ntsiab sib tsoo thiab polishing cov ntaub ntawv yog pob zeb diamond nyob rau hauv kev ua lag luam, thiab nws cov nqi yog kaum los yog ntau pua zaus ntawm β-Sic. Txawm li cas los xij, kev sib tsoo ntawm β-Sic hauv ntau qhov chaw tsis tsawg dua pob zeb diamond. Piv nrog rau lwm cov abrasives ntawm tib qhov me me, β-Sic muaj qhov ua tau zoo tshaj plaws thiab kev ua haujlwm raug nqi.
Raws li polishing thiab sib tsoo cov khoom, nano silicon carbide kuj muaj kev sib txhuam coefficient zoo heev thiab cov khoom siv kho qhov muag zoo heev, uas tau siv dav hauv kev ua microelectronic thiab optoelectronic khoom tsim. Nano silicon carbide polishing thiab sib tsoo cov ntaub ntawv tuaj yeem ua tiav cov peev txheej polishing siab heev, thaum tswj thiab txo qhov roughness thiab morphology, txhim kho qhov zoo ntawm cov khoom thiab kev ua haujlwm ntawm cov khoom.
Hauv cov cuab yeej siv pob zeb diamond, nano silicon carbide yog ib qho tseem ceeb ntxiv uas tuaj yeem txhim kho qhov hnav tsis kam, txiav thiab polishing kev ua tau zoo ntawm cov khoom siv pob zeb diamond. Lub caij no, qhov me me thiab zoo dispersion ntawm SiC tuaj yeem txhim kho kev ua haujlwm ntawm cov khoom siv pob zeb diamond los ntawm kev sib xyaw zoo nrog cov khoom siv cob. Cov txheej txheem ntawm nano SiC rau kev tsim cov khoom siv pob zeb diamond yog yooj yim thiab yooj yim. Ua ntej, nano SiC hmoov yog tov nrog resin hmoov nyob rau hauv ib tug predetermined piv, thiab ces rhuab thiab nias los ntawm ib tug pwm, uas yuav ua tau zoo tshem tawm qhov tsis sib xws ntawm pob zeb diamond hais los ntawm kev siv lub uniform dispersion khoom ntawm SiC nanoparticles, yog li no ho txhim kho lub zog thiab hardness ntawm cov cuab yeej thiab ncua lawv cov kev pab cuam lub neej.
Ntxiv nrog rau kev tsim cov khoom siv pob zeb diamond resin,nanoparticles silicon carbideKuj tseem siv tau rau hauv kev tsim ntau yam abrasives thiab cov cuab yeej ua haujlwm, xws li kev sib tsoo log, ntawv xuab zeb, cov ntaub ntawv polishing, thiab lwm yam. Nrog rau kev nce siab ntawm ntau yam kev lag luam los siv kev ua haujlwm siab thiab cov cuab yeej ua haujlwm zoo thiab cov khoom siv abrasives, nano silicon carbide yeej yuav tsim ntau thiab ntau daim ntawv thov hauv cov teb no.
Hauv kev xaus, nano silicon carbide hmoov muaj daim ntawv thov dav dav raws li cov khoom zoo polishing. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, nano silicon carbide thiab cov cuab yeej siv pob zeb diamond resin yuav raug txhim kho thiab hloov kho mus rau ntau qhov chaw.
Hongwu Nano yog cov chaw tsim khoom lag luam ntawm nano precious hlau hmoov thiab lawv cov oxides, nrog cov khoom lag luam txhim khu kev qha thiab ruaj khov thiab tus nqi zoo heev. Hongwu Nano muab SiC nanopowder. Txais tos tiv tauj peb kom paub ntxiv.
