nanometer silicon carbide / Nano SiC (SiC 40nm 99.9%)
Cov yam ntxwv tseem ceeb ntawmnanometer silicon carbide, ultra-fine silicon carbide hmoov npaj los ntawm cov txheej txheem tshwj xeeb nrog kev ntshiab siab, me me particle loj faib ntau yam, siab tshwj xeeb nto cheeb tsam; nano silicon carbide muaj cov tshuaj ruaj khov, siab thermal conductivity (165W / MK), lub coefficient ntawm thermal expansion me me, siab hardness, Mohs hardness ntawm 9.5, microhardness 2840 ~ 3320kg / mm2 Ua ntej ntawm tag nrho cov ntaub ntawv hnav additives, nws hardness ntawm corundum thiab pob zeb diamond, lub zog kho tshuab yog siab dua corundum; nano silicon carbide muaj zoo heev thermal conductivity, los yog semiconductor, kub siab tiv thaiv oxidation; nano silicon carbide hnav-resistant, kub siab tiv thaiv, corrosion, acid thiab alkali solvent, dav siv hauv cov xim, pleev xim rau sab hauv, ua rau kom hnav tsis kam.
1. Cov ntaub ntawv nylon uas hloov kho tau muaj zog heev: nano-SiC hmoov hauv cov polymer composites muaj kev sib raug zoo, kev sib kis zoo, thiab cov substrate, lub zog tensile ntawm cov nylon alloy hloov kho tau muaj zog ntau dua li PA6 ib txwm muaj nce 150%, kev hnav tsis kam nce ntau dua peb zaug. Feem ntau siv rau cov tsheb thauj khoom uas muaj hlau tiv thaiv, cov khoom siv kauj tsheb, cov tshuab textile, cov tshuab tsuas, cov ntaub, thiab cov khoom siv tsheb ciav hlau tuaj yeem ua tiav qhov kub qis dua sintering densification;
2. Kev hloov kho ntawm cov khoom siv tshwj xeeb engineering plastics polyether ether ketone (PEEK) hnav tsis kam: nano silicon carbide kev kho qhov chaw tom qab lub tuam txhab, ntxiv 5% lossis li ntawd, tuaj yeem txhim kho thiab txhim kho qhov hnav tsis kam ntawm PEEK thiab (txhim kho qhov qub ntau dua 30%);
3. nm silicon carbide hauv lub log tsheb roj hmab: nano silicon carbide, ntxiv txog 2% nyob rau hauv lub premise tsis hloov cov kua nplaum thawj zaug hloov kho, tsis muaj kev cuam tshuam nws cov kev ua tau zoo thiab zoo, qhov kev hnav tsis kam tuaj yeem nce ntxiv los ntawm 20% -40%. Tsis tas li ntawd, 40 nm silicon carbide siv rau hauv cov roj hmab roller, lub tshuab luam ntawv fuser zaj duab xis hnav, cua sov, kub thiab lwm yam khoom roj hmab;
4. Cov hlau nto nano-SiC composite txheej: cov khoom sib xyaw ua ke ntawm cov khoom nanoscale, nickel matrix hlau, qhov chaw hlau los tsim cov khoom ntom ntom, khi zoo heev electrodeposited composite txheej, qhov chaw hlau nrog super-hard (hnav) thiab antifriction self-lubricating kub siab yam ntxwv. Microhardness ntawm cov txheej composite zoo heev txhim kho qhov hnav tsis kam yog nce 2-3 zaug, lub neej kev pabcuam nce 3-5 zaug, lub txheej thiab lub substrate khi peev xwm nce 40%, muaj peev xwm npog, sib xws txheej, du, ntxaws; Tsib lwm daim ntawv thov: kev ua tau zoo siab structural ceramics (xws li rocket nozzles, nuclear kev lag luam, thiab lwm yam), absorbers, anti-hnav roj, high-performance nres pads, siab hardness thiab hnav-resistant hmoov txheej, ceramic composite strengthening thiab toughening, thiab lwm yam.;
kev lag luam aerospace cov qauv ntawm txheej, txheej ua haujlwm, txheej tiv thaiv, cov ntaub ntawv nqus tau, cov ntaub ntawv zais cia, thiab lwm yam;
cov cuab yeej tiv thaiv ntawm cov tank thiab cov tsheb armored; rau cov cuab yeej txiav ceramic, cov cuab yeej txiav, cov cuab yeej ntsuas, pwm;
siv tau rau cov hom phiaj tshwj xeeb ntawm cov khoom siv ceramic, cov khoom siv ceramic, Engineering Ceramics; hluav taws xob; cov khoom siv cua sov hluav taws xob rau kev siv hauv kev lag luam, lub tshuab hluav taws xob deb infrared.
