Chakavanzika chegirini silicon carbide poda yekuvandudza mashandiro ezvakasanganiswa zvinhu
Vaya vakashanda muzvinhu zvakasanganiswa vanoziva kuti zvakanyanya kuoma kubatanidza zvakanakira zvinhu zvakasiyana mundiro yakanaka pane kuyananisa hukama pakati pavamwene nemuroora. Asi kubva pakubuda kwegreen silicon carbide powder, iyo "magic seasoning", iyo inoumbwa zvinhu denderedzwa yakashandura zvakananga "kuvhura mode". Nhasi, ngatiburitsei chidzitiro ichi chisinganzwisisike uye tione kuti murwi uyu wehupfu yakasvibira ungaite sei kuti vatenzi vanodada vakaita secarbon fiber uye ceramics vateerere.
1. “Murwi ane mativi matanhatu” ane chipo
Green silicon carbide poda inozvarwa kuti ive "yehupfu hwekurota" yezvinhu zvinoumbwa. Kuoma kweMohs ndeye 9.5, iyo inongofema yakaipisisa kupfuura diamond. Fekitori yebrake pad muGuangdong yaita kuenzanisa. Iyo inoumbwa zvinhu yakasanganiswa ne 20% yegirini silicon carbide ine kupfeka kuramba indekisi iyo inopetwa katatu pane zvechinyakare zvinhu. Mutungamiriri wewekishopu Lao Huang akabata muenzaniso wacho ndokuti: “Nekuoma uku, haugone kana kusiya mucherechedzo mushure mekuikwiza nejecha kwehafu yeawa!”
The thermal conductivity inotonyanya kutsamwa. Shandong Research Institute yakayera data ikaona kuti thermal conductivity yealuminium-based composite materials ine 15% green silicon carbide yakakwira kusvika 220W/(m·K), inova 30% yakasimba kudarika aruminiyamu yakachena. Technician Xiao Liu akatarisa mufananidzo wekudziya ndokuti: "Uku kudzima kupisa kwakafanana nekuisa mvura yekutonhodza system paCPU!"
Kugadzikana kwemakemikari kwakatonyanya kusiyanisa. Mukuyedzwa kweiyo lining material yepombi yekemikari muNingbo, iyo green silicon carbide composite material yakanyudzwa muconcentrated sulfuric acid kwehafu yegore, uye huremu hwekuremerwa hwaive husingasviki 0.3%. Quality inspector Lao Wang akasimudza sampuli ndokuzvirova dundundu achiti: "Uku kuramba kuonda, kunyange vira raTaishang Laojun rinofanirwa kupfuudza mudzanga!"
2. "Nguva yemashiripiti" yezvikamu zvakabatanidzwa
Dispersion tekinoroji ikozvino yakanaka kwazvo. Imwe kambani muJiangsu yakauya nemusanganiswa we "ultrasound + ball milling", iyo inoparadzira iyo micropowder zvakaenzana kupfuura maparera mumukaka tii. Master Lao Li akasimudza mufananidzo weelectronic microscope ndokuzvirova dundundu achiti: “Tarisa kupararira uku, masvosve anorasika kana akakwira kumusoro!”
Iyo dema tekinoroji yekubatanidza interface yakatonyanya kutyisa. Iyo nano-coupling agent yakagadziriswa nerabhoritari muShanghai yakawedzera simba rekubatanidza pakati peiyo micropowder uye matrix kusvika 150MPa. Mutungamiriri webasa racho akasimudza magirazi ake mudenga ndokuti: “Patakapedzisira kuedza kugera, chigadziriso chacho chakanga chakaremara, asi magirazi acho haana kunonoka!”
3. "Simudza chiitiko" chebvunzo chaiyo yekurwa
Indasitiri yezvemuchadenga yanga ichipenga kwenguva yakareba. Iwo turbine mablades eimwe fekitori yeinjini yekubhururuka muChengdu anoshandisagreen silicon carbidekusimbisa ceramic-based composite zvinhu, uye tembiricha kuramba yakananga kusvika 1600 ℃. Mutyairi webvunzo Lao Zhang akatarisa padashibhodhi ndokumedzerera mate: "Nekuita uku, injini dzejeti dzinofanira kufonera baba!"
Iyo bhatiri bracket yemotokari itsva simba inotonyanya kunakidza. Iyo kabhoni faibha inoumbwa bracket yemugadziri muNingde ine chaiyo simba rakapetwa ka8 pane resimbi mushure mekusanganiswa negirinhi silica carbide. Panguva yekuedza kudhumhana, injiniya wezvokuchengetedza Lao Li akabhabhadzira gonhi remotokari ndokuseka kuti: “Iye zvino muviri wemotokari uyu wafanana nokupfeka mabhati matatu asingapindi bara!”
Munda we5G base station heat sinks unopenga. Iyo aruminiyamu-yakavakirwa inosanganisirwa radiator yemugadziri muHangzhou ine yekupisa yekuwedzera coefficient inodzorwa kusvika 4.8 × 10⁻⁶/℃. Mukuru wezvehunyanzvi akanongedza data reyedzo yekutenderera uye akazvirova dundundu achiti: "Inogona kugadziridzwa kubva -50 ℃ kusvika 200 ℃, uye shanduko yesaizi yakakomba kupfuura Virgo!"
4, "Nguva refu" muakaundi yemutengo
Usatarise mutengo wepamusoro weyunitigreen silicon carbide micropowder, zvine pundutso kana iwe ukaverenga iyo yakazara account. Fekitori yemuchina muChongqing yakaita accounting: kunyangwe mutengo wezvigadzirwa wakawedzera ne25%, hupenyu hwechigadzirwa hwakapetwa kana, uye mutengo wekugadzirisa wakachengetwa mumakore matatu wakakwana kuvaka musangano mutsva. Mudzimai wezvemari akarova karukureta ndokuseka kuti: “Bhizinesi iri rine mari yakawanda kupfuura kukwereta!”
Iko kuvandudzwa kwekugadzirwa kwekugadzira kunotonyanya kufara pachivande. Zvinoenderana nezviyero chaizvo zveotomatiki mutsara wekugadzira muTianjin, nguva yekurapa yezvinhu zvinoumbwa yakapfupikiswa ne40%. Mukuru wemusangano akatarisa pahwindo hombe ndokurova makumbo ake: “Iye zvino kugadzirwa kwacho kwakafanana nokutasva roketi, uye vatengi havasi kuvhunduka kana vachikurudzira maodha!”
Nhasi girini silicon carbide micropowder haisisiri chigadzirwa chepfungwa murabhoritari. Kubva pazvikepe zvemuchadenga zvichibhururuka mudenga kusvika kumotokari itsva dzine simba dzichimhanya pasi, kubva pamachipisi enharembozha akakura semuchindwe kusvika kuma 100-mita akareba eturbine blades, iri kwese kwese. Veterans muindasitiri iyi vanoti chinhu ichi chave kuita gomba mukuita sirin'i yezvinhu zvakaumbwa. Mukuona kwangu, iyi haisi kungovandudza zvinhu zviri nyore, asi "pfuti muruoko" yemabhizimisi emazuva ano. Kana izvi zvikaramba zvichienderera mberi, zvinokwanisika kuti rimwe zuva mabhodhi edu ekuchekeresa achashandisa tekinoroji nhema iyi - mushure mezvose, ndiani asingadi kuti midziyo yavo yekubikira ive padanho rakafanana nemidziyo yemuchadenga?
