Sirrin kore siliki carbide foda don inganta aikin kayan haɗin gwiwa

Wadanda suka yi aiki a cikin kayan haɗin gwiwar sun san cewa yana da wuya a haɗa amfani da kayan aiki daban-daban a cikin tasa mai kyau fiye da daidaita dangantaka tsakanin surukai da surukarta. Amma tun bayan bayyanarkore silicon carbide foda, "Magic seasonings", da'irar kayan da aka haɗa kai tsaye sun kunna "yanayin buɗewa". A yau, bari mu buɗe wannan mayafi mai ban mamaki kuma mu ga yadda wannan tulin koren foda zai iya sa masu girman kai irin su carbon fiber da yumbura su yi biyayya.

1. Mai hazaka "jarumi hexagonal"

Green silicon carbide foda an haife shi don zama "mafarki foda" na kayan haɗin gwiwa. Taurin Mohs shine 9.5, wanda shine kawai numfashi mafi muni fiye da lu'u-lu'u. Wata masana'antar kushin birki a Guangdong ta yi kwatance. Abubuwan da aka haɗa tare da 20% koren silicon carbide yana da ma'aunin juriya wanda ya ninka sau 3 na kayan gargajiya. Daraktan bitar Lao Huang ya taba samfurin ya ce: "Da wannan taurin, ba za ku iya barin tabo ba bayan shafe shi da takarda yashi na rabin sa'a!"

Thermal conductivity ya ma fi m. Cibiyar Bincike ta Shandong ta auna bayanai kuma ta gano cewa yawan zafin jiki na kayan haɗin gwiwar aluminium wanda ke ɗauke da 15% koren silicon carbide ya tashi zuwa 220W/(m·K), wanda ya fi 30% ƙarfi fiye da tsantsar aluminum. Masanin fasaha Xiao Liu ya kalli mai hoton thermal kuma ya ce: "Wannan aikin da ya dace na zubar da zafi yana kama da shigar da tsarin sanyaya ruwa akan CPU!"

Tsawon sinadarai ya ma fi na musamman. A gwajin da aka yi na bututun sinadari a Ningbo, an jika koren siliki carbide mai hade da sinadarin sulfuric acid na tsawon rabin shekara, kuma yawan asarar nauyi bai wuce 0.3%. Ingancin inspector Lao Wang ya ɗaga samfurin kuma ya yi alfahari: "Wannan juriya na lalata, har ma da tanderun alchemy ta Taishang Laojun dole ne ta wuce sigari!"

2. "Lokacin sihiri" na tsari mai hade

Fasahar watsawa yanzu tana da kyau sosai. Wani kamfani a Jiangsu ya fito da wani nau'in "ultrasound + ball milling", wanda ke tarwatsa micropowder fiye da lu'u-lu'u a cikin shayin madara. Jagora Lao Li ya ɗaga hoton na'urar microscope kuma ya yi alfahari: "Ku dubi wannan yawan rarraba, tururuwa za su yi asara idan sun hau!"

Fasahar baƙar fata na haɗin haɗin kai ya fi zafi. Wakilin haɗin haɗin nano wanda wani dakin gwaje-gwaje a Shanghai ya haɓaka ya haɓaka ƙarfin haɗin gwiwa tsakanin micropowder da matrix zuwa 150MPa. Shugaban aikin ya matsa gilashin sa ya ce: “Lokacin da muka yi gwajin shear, na’urar ta lalace, amma kayan ba su ɓata ba!”

3. "Haske wuri" na ainihin gwajin gwagwarmaya

Masana'antar sararin samaniya ta dade tana hauka. Gilashin injin turbine na wani masana'antar injin jirgin sama a Chengdu amfanikoren siliki carbidedon ƙarfafa yumbu-tushen kayan haɗin gwiwa, da juriya na zafin jiki kai tsaye zuwa 1600 ℃. Direban gwajin Lao Zhang ya kalli gaban dashboard ya fashe: "Da wannan aikin, injinan jet dole ne su kira baba!"

Bangaren baturi na sabbin motocin makamashi ya ma fi ban sha'awa. Bangaren haɗin fiber carbon fiber na masana'anta a Ningde yana da takamaiman ƙarfi na ƙarfe sau 8 bayan an haɗe shi da koren silicon carbide. A lokacin gwajin haɗarin, injiniyan lafiya Lao Li ya lallaba ƙofar motar yana dariya: “Yanzu wannan jikin motar tana kama da riguna masu kariya uku!”

Filin 5G na tashar zafi mai zafi yana da hauka. Aluminum na tushen hadadden radiator na masana'anta a Hangzhou yana da ƙimar haɓakar haɓakar thermal mai sarrafawa zuwa 4.8 × 10⁻⁶/℃. Daraktan fasaha ya nuna bayanan gwajin zagayowar thermal kuma ya yi alfahari: "Za a iya daidaita shi daga -50 ℃ zuwa 200 ℃, kuma girman canjin ya fi Virgo tsanani!"

4, "Dogon lokaci" a cikin asusun farashi

Kada ku dubi babban farashin naúrarkoren silicon carbide micropowder, tabbas yana da riba idan kun lissafta jimlar asusun. Wata masana'antar injina a Chongqing ta yi lissafin kuɗi: ko da yake farashin albarkatun ƙasa ya karu da kashi 25%, rayuwar samfuran ta ninka sau huɗu, kuma kuɗin kulawa da aka adana a cikin shekaru uku ya isa don gina sabon bita. Matar mai kuɗin ta buga lissafin kuma ta yi dariya: "Wannan kasuwancin ya fi riba fiye da lamuni!"

Haɓakawa a cikin ingantaccen samarwa ya fi farin ciki a asirce. Dangane da ainihin ma'auni na layin samarwa mai sarrafa kansa a Tianjin, an rage lokacin warkewar kayan haɗin gwiwa da kashi 40%. Daraktan bitar ya kalli babban allo ya mare kafafunsa: "Yanzu karfin samarwa ya zama kamar hawan roka, kuma abokan ciniki ba sa firgita lokacin da suke ba da umarni!"

Koren silicon carbide micropowder na yau ba samfurin ra'ayi bane a cikin dakin gwaje-gwaje. Daga kumbon da ke shawagi a sararin sama zuwa sabbin motocin makamashi da ke gudana a kasa, daga guntuwar wayar hannu masu girman dabino zuwa injin injin injin dakon iska mai tsayin mita 100, yana ko'ina. Tsohon soji a cikin masana'antar sun ce wannan abu ya sanya rami a cikin rufin aikin kayan haɗin gwiwa. A ganina, wannan ba kawai haɓaka kayan abu ba ne kawai, amma "harbi a hannu" don masana'antun zamani. Idan wannan yanayin ya ci gaba, mai yiyuwa ne wata rana cewa allunan yankanmu za su yi amfani da wannan baƙar fata - bayan haka, wanene ba ya son kayan dafa abinci su kasance daidai da kayan sararin samaniya?
