Hexagonal boron nitride (HBN) hmoov muaj kev ua tau zoo ntawm cov cua sov, cov khoom ntug, kev ruaj khov tshuaj lom neeg thiab lubricity. Nws qhov kub tiv thaiv oxidation tshaj 2000 ° C, thiab nws kuj muaj lubricity zoo ntawm qhov kub siab. Nws yog siv rau hauv kev npaj ntawm cubic boron nitride, cov txheej txheem kub siab, cov khoom sau, hBN agglomerates, thiab lwm yam. Boron oxide
(1) Kev lag luam khoom siv Superhard. Siv los npaj cubic boron nitride. Cubic boron nitride yog hexagonal boron nitride ntxiv nrog lithium-based lossis magnesium-based catalyst, uas tuaj yeem hloov mus ua cubic boron nitride hauv qab qhov kub siab. Tam sim no, kev lag luam hauv tsev siv ntau dua 400 tons ntawm hexagonal boron nitride txhua xyoo.
(2) Kev lag luam pleev xim. Tom qab hBN raug coated rau ntawm hlau, ceramics thiab lwm yam khoom siv, nws tuaj yeem ua rau cov khoom muaj qhov zoo ntawm lubricity thiab tiv thaiv kev lo (tso tawm), thiab tuaj yeem tiv thaiv lossis txo qhov tshuaj lom neeg ntawm cov khoom siv thiab cov yaj, thiab txhim kho lub neej ntawm cov khoom siv; Ntau yam txheej txheem tshiab uas ua rau muaj cua sov rau radiators thiab cov khoom siv hluav taws xob kom nce cua sov dissipation. Nws yog qhov tsim nyog rau photoelectric industrial radiators, cov khoom siv hluav taws xob txias modules, lub zog txias modules, tsheb radiators, roj txias, gearbox roj txias, thiab lwm yam txias. .
(3) Kev lag luam khoom siv hluav taws xob. Thaum siv los ua cov khoom siv rau cov khoom siv hluav taws xob siab, hBN muaj kev tiv thaiv kub zoo heev, tiv thaiv corrosion zoo, coefficient nthuav dav thermal qis thiab tus nqi cua sov siab. Nws yog cov khoom siv thermal ntug tsim nyog thiab tuaj yeem txhim kho tus nqi thermal ntawm cov khoom siv hluav taws xob raws li resin.
(4) Kev lag luam tshuaj pleev ib ce zoo heev. Thaum siv los ua cov khoom siv tshuaj pleev ib ce zoo heev, nws tuaj yeem ua rau kom muaj kev nplaum thiab zais lub zog ntawm cov tshuaj pleev ib ce, thiab nws muaj qhov zoo li nplua, ua rau cov tshuaj pleev ib ce me me, yooj yim siv, yooj yim ntxuav thiab tshem tawm, thiab nws ua rau tib neeg lub cev puas tsuaj. Tam sim no, kev lag luam tshuaj pleev ib ce zoo heev siv ntau dua 200 tons ntawm hexagonal boron nitride txhua xyoo.
(5) Kev lag luam khoom siv lubricating. Ua ib qho khoom ntxiv rau cov khoom siv lubricating khov kho thiab kua. Kev ntxiv cov roj lubricating tuaj yeem txhim kho kev siv roj, txhim kho kev ua haujlwm ntawm lub tog raj kheej, thiab muaj cov txiaj ntsig zoo rau kev txuag hluav taws xob.
(6) Kev lag luam ceramic high-tech, siv los npaj hBN agglomerates. hBN agglomerates muaj cov thermal conductivity siab, kev ua haujlwm kub zoo heev, cov khoom hluav taws xob thiab dielectric zoo heev, thiab feem ntau siv los npaj cov khoom kub thiab siab siab dissipation, cov khoom hluav taws xob kub siab, crucibles thiab pwm, thiab cov qhov rai siab permeability thiab ruaj khov Missile radome, microwave antenna qhov rai thiab lwm yam khoom.
Peb muaj ntau hom thiab zooHexagonal boron nitride, cov lus qhia raws li nram no
