Chakavanzika cheupfu hwegirini hwesilicon carbide kuti zvinhu zvakagadzirwa zvakasanganiswa zvishande zvakanaka

Avo vakamboshanda mukugadzira zvinhu zvakasanganiswa vanoziva kuti zvakaoma kusanganisa zvakanakira zvinhu zvakasiyana mudhishi rakanaka pane kuyananisa hukama huripo pakati pavamwene nemuroora. Asi kubva pakatangaupfu hwegirini hwesilicon carbide, "zvinonhuhwirira zvemashiripiti", denderedzwa rezvinhu zvakasanganiswa ravhura zvakananga "nzira yekutanga". Nhasi, ngatiburitsei chifukidziro ichi chisinganzwisisike toona kuti murwi uyu weupfu hwegirini ungaite sei kuti vatenzi vanodada vakaita se carbon fiber ne ceramics vateerere.

1. "Murwi ane chipo che" gamba rematanhatu"

Upfu hwegirini hwesilicon carbide hwakazvarwa huri "upfu hweroto" hwezvinhu zvakasanganiswa. Kuomarara kweMohs kuri 9.5, izvo zvinongova mweya wakaipa kupfuura dhaimani. Fekitori yemabhureki muGuangdong yakaenzanisa. Zvinhu zvakasanganiswa zvakasanganiswa ne20% green silicon carbide zvine index yekudzivirira kupfekwa yakapetwa katatu pane zvinhu zvechinyakare. Mutungamiriri weworkshop Lao Huang akabata muenzaniso ndokugunun'una achiti: "Nekuomarara uku, haugone kusiya chiratidzo mushure mekukwesha nesandpaper kwehafu yeawa!"

Kufambiswa kwemhepo inopisa kwakanyanya kuipa. Shandong Research Institute yakayera data ndokuona kuti kufambiswa kwemhepo inopisa kwezvinhu zvakagadzirwa nearuminiyamu zvine 15% green silicon carbide kwakakwira kusvika ku220W/(m·K), iyo yakasimba ne30% kupfuura aruminiyamu yakachena. Nyanzvi Xiao Liu akatarisa mufananidzo wekupisa ndokudanidzira achiti: "Kushanda uku kwekupisa kwakafanana nekuisa sisitimu yekutonhodza mvura paCPU!"

Kugadzikana kwemakemikari kwakatosiyana. Mukuyedzwa kwechinhu chemukati chepombi yemakemikari muNingbo, chinhu chegirini chesilicon carbide chakanyikwa musulfuric acid yakakora kwehafu yegore, uye mwero wekurasikirwa nehuremu waive pasi pe0.3%. Muongorori wemhando yepamusoro Lao Wang akasimudza muenzaniso ndokuzvikudza achiti: "Kudzivirira ngura uku, kunyangwe chitofu chealchemy chaTaishang Laojun chinofanira kupfuudza fodya!"

2. "Nguva yemashiripiti" yemaitiro ekubatanidza

Tekinoroji yekupararira yava yakanaka kwazvo. Imwe kambani muJiangsu yauya nemusanganiswa we "ultrasound + ball milling", iyo inoparadzira micropowder zvakaenzana kupfuura maparera ari mutii yemukaka. Master Lao Li akasimudza mufananidzo we electron microscope ndokuzvikudza achiti: "Tarisa huwandu hwekupararira uku, masvosve acharasika kana akakwira kumusoro!"

Tekinoroji nhema yekubatanidza interface yakanyanya kuipa. Iyo nano-coupling agent yakagadzirwa nerabhoritari muShanghai yakawedzera simba rekubatanidza pakati pe micropowder ne matrix kusvika pa 150MPa. Mutungamiriri wepurojekiti akasimudza magirazi ake ndokuti: "Nguva yekupedzisira yatakaita shear test, fixture yakanga yakaremara, asi composite material haina kupatsanurwa!"

3. "Simbisa chiitiko" chekuedza kwehondo chaiko

Indasitiri yendege yagara ichipenga kwenguva yakareba. Mapazi eturbine eimwe fekitori yeinjini dzendege muChengdu anoshandisakabhidhi yegirini yesiliconkusimbisa zvinhu zvakagadzirwa neceramic-composite, uye kuramba tembiricha kuri kusvika 1600℃. Mutyairi wekuyedza Lao Zhang akatarisa padashboard ndokudonhedza mate: "Nekushanda uku, mainjini ejeti anofanira kufonera baba!"

Chivharo chemabhatiri chemotokari itsva dzinoshandisa simba chinotonyanya kufadza. Chivharo checarbon fiber chakagadzirwa nemugadziri weNingde chine simba rakapetwa kasere pane resimbi mushure mekusanganiswa ne green silicon carbide. Panguva yekuedzwa kwekurovera, mainjiniya wekuchengetedza Lao Li akarova gonhi remotokari ndokuseka achiti: "Zvino muviri wemotokari iyi wakaita sekunge wakapfeka majasi matatu asingapindi mabara!"

Nzvimbo ye5G base station heat sinks yakanyanya kuipa. Iyo aluminium-based composite radiator yemugadziri muHangzhou ine thermal expansion coefficient inodzorwa kusvika ku4.8×10⁻⁶/℃. Mutungamiriri wehunyanzvi akataura nezve data rekuyedza thermal cycle ndokuzvirumbidza achiti: "Inogona kugadziriswa kubva -50℃ kusvika 200℃, uye shanduko yehukuru yakakomba kupfuura Virgo!"

4, "Kutonga kwenguva refu" muakaundi yemari

Usatarise mutengo wepamusoro weyunitiupfu hwegirini hwesilicon carbide, zvinopa pundutso chaiyo kana ukaverenga account yese. Fekitori yemichina muChongqing yakaita accounting: kunyangwe mutengo wezvinhu zvakagadzirwa wakawedzera ne25%, hupenyu hwechigadzirwa hwakapetwa kana, uye mari yekugadzirisa yakachengetedzwa mumakore matatu yakakwana kuvaka workshop itsva. Mukadzi wezvemari akadzvanya karukureta ndokuseka achiti: "Bhizinesi iri rine pundutso kupfuura kukweretesa mari!"

Kuvandudzwa kwekushanda zvakanaka kwekugadzira zvinhu kwakawedzera mufaro muchivande. Zvichienderana nekuyera chaiko kwemutsetse wekugadzira otomatiki muTianjin, nguva yekushanda kwezvinhu zvakasanganiswa yakapfupikiswa ne40%. Mutungamiriri weworkshop akatarisa pachidzitiro chikuru ndokurova makumbo ake achiti: "Iye zvino kugona kwekugadzira kwakafanana nekutasva roketi, uye vatengi havasi kutya pavanokurudzira maodha!"

Upfu hwe silicon carbide micropowder hwemazuva ano hahusisiri chigadzirwa chepfungwa murabhoritari. Kubva kuzvinhu zvemuchadenga zvinobhururuka mudenga kusvika kumotokari itsva dzinoshandisa simba dzinomhanya pasi, kubva kumachipisi efoni akaenzana nemuti wemuchindwe kusvika kumaburi emhepo ane hurefu hwemamita 100, zviri kwese kwese. Vakuru vekare muindasitiri vanoti chinhu ichi chaburitsa gomba padenga rekushanda kwezvinhu zvakasanganiswa. Mukufunga kwangu, uku hakusi kungovandudza zvinhu chete, asi "chinhu chakakosha" kumaindasitiri emazuva ano. Kana maitiro aya akaramba aripo, zvinokwanisika kuti rimwe zuva mabhodhi edu ekucheka achafanira kushandisa tekinoroji iyi nhema - pamusoro pezvose, ndiani asingade kuti midziyo yavo yekicheni ive padanho rakafanana nezvinhu zvemuchadenga?
