Kugadzira Nzira dzeSilicon Carbide Ceramics

Kugadzira Nzira dzeSilicon Carbide Ceramics: Maonero Akazara

Iyo yakasarudzika crystal chimiro uye zvimiro zvesilicon carbide ceramics inobatsira kune yayo yakanakisa zvivakwa. Ivo vane simba rakanakisa, kuomarara kwakanyanya, kupfeka kwakanakisa kuramba, corrosion resistance, high thermal conductivity uye yakanaka thermal shock resistance. Izvi zvivakwa zvinogadzira silicon carbide ceramics yakanakira ballistic application.

Kugadzirwa kwesilicon carbide ceramics kazhinji kunotora nzira dzinotevera:

1. Compression molding: Compression molding inzira inoshandiswa zvakanyanya pakugadzira silicon carbide bulletproof sheets. Iyo nzira iri nyore, iri nyore kushanda, yakakwirira mukubudirira uye yakakodzera kuenderera kugadzirwa.

2. Injection molding: Injection molding ine yakanakisa kuchinjika uye inogona kugadzira yakaoma maumbirwo uye zvimiro. Iyi nzira inonyanya kubatsira pakugadzira yakakosha-yakaumbwa nesilicon carbide ceramic zvikamu.

3. Cold isostatic pressing: Cold isostatic pressing inosanganisira kushandiswa kwesimba rakafanana kune muviri wakasvibirira, zvichiita kuti yunifomu density kugoverwa. Iyi tekinoroji inonatsiridza zvakanyanya kuita kwechigadzirwa uye yakakodzera kugadzirwa kwepamusoro-kuita silicon carbide ceramics.

4. Gel jekiseni molding: Gel jekiseni molding ichiri chitsva pedyo net mambure saizi kuumba nzira. Muviri wakasvibira unogadzirwa une chimiro chakafanana uye simba rakakwirira. Izvo zvakawanikwa zveceramic zvikamu zvinogona kugadziriswa nemichina yakasiyana-siyana, iyo inoderedza mutengo wekugadzirisa mushure mekupisa. Gel jekiseni molding inonyanya kukodzera kugadzirwa kwesilicon carbide ceramics ine yakaoma zvimiro.

Nekushandisa idzi nzira dzekugadzira, vagadziri vanogona kuwana emhando yepamusoro silicon carbide ceramics ine yakanakisa mechanic uye ballistic zvivakwa. Iko kugona kuumba silicon carbide ceramics muakasiyana maumbirwo uye zvimiro zvinobvumira kugadzirisa uye optimization kuti isangane nezvinodiwa chaizvo zvekushandisa kwakasiyana.

Pamusoro pezvo, iyo inodhura-inoshanda yesilicon carbide ceramics inowedzera kukwezva kwayo seyepamusoro-inoshanda ballistic-resistant zvinhu. Uku kusanganiswa kwezvinhu zvinodikanwa uye mutengo unonzwisisika unoita kuti silicon carbide ceramics ive mukwikwidzi akasimba munzvimbo yezvombo zvemuviri.

Mukupedzisa, silicon carbide ceramics ndiyo inotungamira ballistic zvinhu nekuda kweakanakisa zvivakwa uye nzira dzakasiyana dzekuumba. Chimiro chekristaro, simba, kuoma, kupfeka kuramba, corrosion resistance, thermal conductivity uye thermal shock resistance yesilicon carbide ceramics inoita kuti ive sarudzo inofadza yevagadziri nevatsvakurudzi. Neakasiyana siyana ekugadzira matekiniki, vagadziri vanogona kugadzira silicon carbide ceramics kuti isangane nemashandisirwo chaiwo, kuve nechokwadi chekuita kwakanyanya uye kuchengetedzwa. Ramangwana resilicon carbide ceramics riri kuvimbisa sezvavanoramba vachigadzira uye vachiita zvakanaka mumunda we ballistic zvinhu.

Nezvekudzivirira kwe ballistic, kusanganiswa kwemashizha e polyethylene uye kuiswa kweceramic kwakaratidza kuti inoshanda zvikuru. Pakati pemhando dzakasiyana dzeceramic sarudzo dziripo, silicon carbide yakwezva kutarisisa kukuru kumba nekune dzimwe nyika. Mumakore achangopfuura, vaongorori uye vagadziri vanga vachiongorora kugona kwesilicon carbide ceramics seyakakwira-performance ballistic-resistant zvinhu nekuda kwehunhu hwayo hwakanaka uye ine mwero mutengo.

Silicon carbide ikamu rinoumbwa nekurongedza Si-C tetrahedron, uye ine mafomu maviri ekristaro, α uye β. Pasintering tembiricha iri pasi pe1600 ° C, silicon carbide iripo muchimiro che β-SiC, uye kana tembiricha inopfuura 1600 ° C, silicon carbide inoshanduka kuita α-SiC. Iyo covalent bond ye α-silicon carbide yakasimba kwazvo, uye inogona kuchengetedza yakakwirira-yakasimba chisungo kunyangwe pakupisa kwakanyanya.
