Dhaimondi rinokuya vhiri rinoshandisa diamond abrasive seyakabikwa, uye rinoshandisa simbi poda, resin poda, ceramics uye electroplated simbi semabhandi zvichiteerana.The denderedzwa bonded abrasive tool ine kuburikidza neburi pakati inonzi diamond grinding vhiri (alloy grinding vhiri).

Iyo resin-yakasungwa nedhaimani vhiri rekukuya kazhinji ine hupenyu hwakaderera uye haigone kuzadzisa zvinodiwa zvemberi manhamba ekudzora maturusi emuchina.Hupenyu hupfupi hunonyanya kukonzerwa nekusapfeka zvakanaka kweresin bond pachayo kana simba rekubata pasi padhaimani, izvo zvinoita kuti zvidimbu zvedhaimondi zvidonhe nguva isati yakwana panguva yekukuya.Naizvozvo, maitiro ekuvandudza kupfekedzwa kwekupokana kweresin bond uye kuvandudza simba rekubata resin padhaimani rave kiyi yekuvandudza hupenyu hwesevhisi resin bond diamond vhiri rekukuya.

Kuwedzerwa kwesilicon carbide ndebvu kunogona kuvandudza zvakanyanya simba, kuoma, kupisa kupisa, kupenya, nezvimwe zvechisungo uye vhiri rekukuya.Silicon carbide whiskers ine yakasarudzika mechanic uye physicochemical zvimiro senge kuomarara kwakanyanya, kusimba kwakanyanya (kuoma), uye yakanakisa kupfeka kuramba, saka anoshandiswa zvakanyanya musimbi, ceramics, mapurasitiki, nezvimwe.

Kusimbisa uye kuomeswa kwezvinhu uye zvakaumbwa zvinhu kuvandudza kusimba kwezvakaumbwa zvinhu uye kudzivirira shrinkage uye deformation.Chimiro chesilicon carbide ndebvu dzakafanana netsono, kunyanya kuomarara kwayo kweWebster iri padyo nedhaimondi uye ine kusimba kwakanaka uye kusapfeka, uye kana ichienzaniswa nembeu dzinoputika, kunyangwe dhayamita rakafanana nehukuru hwezviyo zvinoputika, pane ndebvu. yehumwe hurefu hunosanganiswa neMumiririri ane nzvimbo yakakura yekubatanidza uye simba rekubatanidza, iyo inovandudza zvikuru hupenyu hwebasa regumbo rekukuya.

Iyo β-mhando micron-saizisilicon carbide ndebvuinogadzirwa neHongwu Nano ine hunhu hwekuchena kwepamusoro uye yakanaka morphology, uye ndizvo zvinofarirwa zvinhu zvekusimbisa uye kuomesera zvakasiyana-siyana zvesimbi-based, ceramic-based uye resin-based composite zvinhu.Kusimbisa kwayo uye kuomesera maitiro uye chiyero chekushandisa hachifananidzwe nezvimwe zvinhu.

Beta silicon carbide ndebvu dzakafanana netsono sekristaro imwechete.Sekristaro yeatomu, ine density yakaderera, yakakwirira kunyunguduka, simba rakakwirira, yakakwirira modulus, yakaderera kupisa kwekuwedzera kwekuwedzera, uye hunhu hwakanaka hwakadai sekusapfeka, kusaita ngura, kupisa kwekushisa kwepamusoro, oxidation resistance, etc. Inonyanya kushandiswa pakuita simbi base, ceramic base , Kusimbisa uye kuomesera kweresin-based composite zvinhu, zvakanyanya kunatsiridza zvimiro zvezvakaumbwa zvinhu.
