Mumunda wedziviriro yemazuva ano, nekuenderera mberi kwekuvandudzwa kwesimba rechombo, zvinodiwa zvebulletproof zvinhu zviri kuwedzera kuomarara.Silicon carbide, chinhu chinoratidzika sechinhuwo zvacho asi chine simba guru, chiri kubuda zvishoma nezvishoma sechinodiwa chitsva muindasitiri isingapindi bara. Nhasi, tichazarura chidzitiro chisinganzwisisike chesilicon carbide bulletproof.
1, Kuzarura nheyo yebulletproof
Nheyo yekudzivirira kwezvombo iri mukushandisa simba re projectiles, ichidzinonotsa kusvika dzarasikirwa nenjodzi. Zvigadzirwa zvesimbi zvechinyakare zvinotsamira pane deformation yepurasitiki kutora simba, nepo ceramic zvinhu zvinozadzisa chinangwa ichi kuburikidza neyakasiyana diki yekupwanya maitiro. Kutora silicon carbide bulletproof ceramics semuenzaniso, kana projectile yakanganisa, purojekiti inotanga kugomara ipapo ipapo panzvimbo yekubata, uye iyo ceramic pamusoro inopwanyika kuita nzvimbo yakaoma yakatsemuka. Iyi nzira yakafanana nekupa projectile "sando" uye kutanga kutora simba; Zvadaro, purojekiti yakasvibiswa yakaramba ichienderera mberi, ichibvisa nzvimbo yakaparadzana uye ichigadzira chidimbu chinopfuurira chezvidimbu zveceramic; Pakupedzisira, iyo ceramic inoputsika pasi pekunetseka kwekunetseka, uye iyo backplate inotanga kukanganisa. Iyo yakasara simba inotorwa zvachose ne deformation ye backplate material.
2, Sei silicon carbide ichigona kuva bulletproof?
Silicon carbide ikomboni inonyanya kuumbwa necovalent bond, uye yayo Si-C zvisungo zvinogona kuchengetedza simba rakakwirira pakupisa kwakanyanya. Ichi chakasarudzika chimiro chinopa silicon carbide ceramics ine akawanda akanakisa zvivakwa. Iine kuomarara kwakanyanya, yechipiri chete kudhaimondi, cubic boron nitride, uye boron carbide pakati pezvakajairika zvinhu. Zvakafanana nemurwi akapfeka nhumbi dzokurwa dzakaoma, anokwanisa kurwisa zvakasimba projectile impact; Panguva imwe cheteyo, ine density yakaderera uye inoreruka pakurema kana yagadzirwa mumidziyo isingapindi bara. Kunyangwe iri yehondo yemunhu kana yakashongedzerwa pamotokari nendege, haizove mutoro wekuwedzera, asi inogona kuvandudza kufamba kwemauto ekurwa. Pamusoro pezvo, silicon carbide zvakare ine yakanaka kugadzikana kwemafuta uye makemikari ekudzivirira, uye inogona kugadzikana kuita basa remabara munzvimbo dzakasiyana dzakaoma.
3, Izvo zvakasarudzika zvakanakira reaction sintered silicon carbide muzvikamu zvakagadzirirwa
Mukugadzirira kwesilicon carbide ceramics, reaction sintered silicon carbide (RBSiC) inomira pachena, kunyanya yakakodzera kugadzirwa kwechikamu, nekuda kwezvikonzero zvinotevera:
1. High density uye simba guru: Pasi pemamiriro ekushisa kwepamusoro, kabhoni yemahara inopindirana nesilicon yemvura kuti ibudise makristasi matsva esilicon carbide. Panguva imwecheteyo, silicon yakasununguka inopinda uye inozadza pores, ichiwedzera zvakanyanya kuwanda kwezvinhu, inenge ichiswedera kune theoretical density. Izvi hazvingope zvinhu chete zvine simba rekumanikidza uye kukotama, asi zvakare zvinopa kunaka kupfeka kuramba, izvo zvinokwanisa kumirisana nekumanikidza kwakanyanya uye nepamusoro pemamiriro ezvinhu, kusangana nezvinodiwa zvakasimba zvezvikamu zvakagadziridzwa zvesimba uye kusimba.
2. Controllable microstructure: The reaction sintering process inogona kunyatso kudzora kukura kwezviyo, kugadzira diki uye yunifomu microstructures. Iyi yakanaka microstructure inowedzera kuwedzera ma mechanics ezvinyorwa, zvichiita kuti irambe yakagadzikana uye isinganyanyi kutsemuka kana kukuvadzwa kana yakatarisana nekunetseka kwakasiyana kwakaoma, ichipa vimbiso yakasimba yekuvimbika kwezvikamu zvakagadziridzwa.
3. High dimensional kurongeka: Panguva ye densification process, dimensional shanduko ye reaction sintered silicon carbide ishoma, izvo zvakakosha kune zvakajairwa zvikamu. Ingave iri murwi mumwechete bulletproof plug ine maumbirwo akaomarara kana chinhu chakakosha chekudzivirira chemotokari ine zvakaomesesa saizi zvinodiwa, anogona kugadzirwa chaizvo kuti ave nechokwadi chekuenderana nemidziyo.
4. Kugadzikana kwakanaka kwemakemikari: Reaction sintered silicon carbide ine inenge isina maburi akazaruka, zvichiita kuti zviome kuti okisijeni uye zvinhu zvinopisa zvipinde mukati mechinhu, nokudaro kuva neoxidation yakasimba zvikuru uye kusagadzikana kwemarara. Izvi zvinoreva kuti zvakagadziridzwa silicon carbide bulletproof zvigadzirwa zvinogona kuramba zvakagadzikana kuita, kuwedzera hupenyu hwesevhisi, uye kuderedza mari yekugadzirisa munzvimbo dzakaomarara dzechisikigo kana makemikari kwenguva yakareba.
4, Silicon carbide bulletproof application munda
Nekuita kwayo kwakanaka, silicon carbide bulletproof zvinhu zvakashandiswa zvakanyanya muminda yakawanda:
1. Zvishandiso zvemunhu oga: silicon carbide bulletproof vest lining, bulletproof helmet, nezvimwewo, inopa masoja ane huremu uye kudzivirira kwepamusoro, achivabvumira kuchinjika kurwa panhandare yehondo nepo vaine chengetedzo yakavimbika yakachengeteka.
2. Motokari dzakakosha: dzakadai semotokari dzehondo, motokari dzekutakura mari, dzinopesana nehugandanga uye motokari dzekudzivirira mhirizhonga, nezvimwewo, dzakashongedzerwa nesilicon carbide ceramic armor muzvikamu zvakakosha, izvo zvinogona kunyatsodzivisa kurwiswa kwezvombo zvakasiyana-siyana uye kudzivirira kuchengetedzwa kwevashandi uye zvinhu zvinokosha mukati memotokari.
3. Aerospace: Silicon carbide bulletproof zvinhu zvinoshandiswa pazvikopokopo zvine zvombo uye dzimwe ndege kuderedza uremu hwadzo, kuvandudza mafambiro endege, uye kuwedzera kugona kwavo kudzivirira pamoto wemuvengi, kuve nechokwadi kuchengetedzwa kwendege.
Nekuenderera mberi kwekufambira mberi kwetekinoroji, silicon carbide bulletproof zvinhu zvinoramba zvichigadzira uye nekuvandudza, kuvaka tambo yakasimba yekudzivirira kuchengetedza kuchengetedza. Kana iwe uchifarira zvikamu zvakagadziridzwa zve reaction sintered silicon carbide ceramics, ndapota inzwa wakasununguka kutibata nesu.
