Chinsinsi cha green silicon carbide powder kuti apititse patsogolo magwiridwe antchito azinthu zophatikizika

Amene agwira ntchito muzinthu zophatikizika amadziwa kuti ndizovuta kwambiri kuphatikiza ubwino wa zipangizo zosiyanasiyana mu mbale yabwino kusiyana ndi kugwirizanitsa ubale pakati pa apongozi ndi apongozi ake. Koma kuyambira zikamera wagreen silicon carbide ufa, "zokometsera zamatsenga", bwalo lazinthu zophatikizika latsegula mwachindunji "kutsegulira". Lero, tiyeni tivumbulutse chophimba chodabwitsachi ndikuwona momwe mulu wa ufa wobiriwirawu ungapangitse ambuye onyada monga carbon fiber ndi ceramics kumvera.

1. “Wankhondo wamakona atatu” wamphatso

Green silicon carbide powder amabadwa kukhala "ufa wamaloto" wazinthu zophatikizika. Kuuma kwa Mohs ndi 9.5, komwe kumangokhala koyipa kuposa diamondi. Fakitale ya brake pad ku Guangdong yayerekeza. Zinthu zophatikizika zosakanikirana ndi 20% zobiriwira za silicon carbide zili ndi index yodzitchinjiriza yomwe ili kuwirikiza katatu kuposa zida zachikhalidwe. Woyang’anira msonkhanowo a Lao Huang anakhudza chitsanzocho n’kunena kuti: “Ndi kulimba kumeneku, simungasiye ngakhale chizindikiro mutachipaka ndi sandpaper kwa theka la ola!”

The matenthedwe conductivity ndi moipitsitsa kwambiri. Shandong Research Institute yayeza deta ndipo yapeza kuti matenthedwe a aluminiyamu opangidwa ndi zinthu zopangidwa ndi 15% zobiriwira za silicon carbide zidakwera mpaka 220W/(m·K), zomwe ndi 30% zamphamvu kuposa aluminiyamu yoyera. Katswiri Xiao Liu anayang'anitsitsa chithunzi chotenthacho ndipo anafuula kuti: "Kutentha kumeneku ndikofanana ndi kukhazikitsa makina ozizirira madzi pa CPU!"

Kukhazikika kwamankhwala ndikopadera kwambiri. Poyesa zida zapaipi yamankhwala ku Ningbo, zinthu zobiriwira za silicon carbide zidaviikidwa mu sulfuric acid wokhazikika kwa theka la chaka, ndipo kuchepa kwake kunali kosakwana 0.3%. Woyang'anira zaubwino a Lao Wang adanyamula chitsanzocho ndikudzitama kuti: "Kukana dzimbiri uku, ngakhale ng'anjo ya Taishang Laojun ya alchemy iyenera kudutsa ndudu!"

2. "Mphindi yamatsenga" ya ndondomeko yamagulu

Ukadaulo wobalalika tsopano ndi wabwino kwambiri. Kampani ina ku Jiangsu yabwera ndi kuphatikiza kwa "ultrasound + mpira mphero", yomwe imabalalitsa micropowder mofanana kwambiri kuposa ngale mu tiyi wamkaka. Master Lao Li ananyamula chithunzi cha maikulosikopu ya ma elekitironi nadzitama kuti: “Taonani kuchuluka kwa kagawidwe kameneka kameneka, nyerere zitayika ngati zitakwera m’mwamba!”

Ukadaulo wakuda wophatikizira mawonekedwe ndiwowopsa kwambiri. Nano-coupling agent yopangidwa ndi labotale ku Shanghai yawonjezera mphamvu yolumikizana pakati pa micropowder ndi matrix mpaka 150MPa. Woyang’anira ntchitoyo anakweza magalasi ake n’kunena kuti: “Nthaŵi yomaliza imene tinayesako kukameta ubweya wa nkhosa, makinawo anali opunduka, koma magalasiwo sanachedwe!”

3. "Unikani chithunzi" cha mayeso enieni ankhondo

Makampani opanga ndege akhala akupenga kwa nthawi yayitali. Ma turbine masamba a fakitale ina ya injini za ndege ku Chengdu amagwiritsa ntchitogreen silicon carbidekulimbikitsa zida zophatikizika za ceramic, ndipo kukana kutentha kumafika mpaka 1600 ℃. Woyendetsa mayeso a Lao Zhang adayang'ana pa bolodi ndikugwetsa: "Ndikuchita izi, ma injini a jet ayenera kuyimbira abambo!"

Battery bracket ya magalimoto atsopano amphamvu ndi yosangalatsa kwambiri. Bokosi lophatikizana la carbon fiber la wopanga ku Ningde lili ndi mphamvu zenizeni nthawi 8 kuposa zachitsulo zitasakanizidwa ndi silicon carbide yobiriwira. Poyesa kugundana kwa galimotoyo, katswiri wa zachitetezo Lao Li anasisita chitseko cha galimotoyo n’kuseka kuti: “Tsopano thupi la galimotoli lili ngati kuvala malaya otchinga zipolopolo zigawo zitatu!”

Munda wa 5G base station heat sinks ndi wamisala. Radiyeta yopangidwa ndi aluminiyamu yopangidwa ndi wopanga ku Hangzhou ili ndi chowonjezera chamafuta chomwe chimayendetsedwa mpaka 4.8×10⁻⁶/℃. Woyang'anira zaukadaulo adalozera ku data yoyesa kuzungulira kwa matenthedwe ndipo adadzitamandira kuti: "Itha kusinthidwa kuchokera ku -50 ℃ kupita ku 200 ℃, ndipo kusintha kwa kukula ndikovuta kwambiri kuposa Virgo!"

4, "Nthawi yayitali" mu akaunti yamtengo wapatali

Musayang'ane mtengo wapamwamba wa unitgreen silicon carbide micropowder, ndizopindulitsadi mukamawerengera akaunti yonse. Fakitale yamakina ku Chongqing yawerengera ndalama: ngakhale mtengo wazinthu zopangira zidakwera ndi 25%, moyo wazinthu zomwe zapangidwazo zakwera kanayi, ndipo mtengo wokonzanso womwe wasungidwa m'zaka zitatu ndiwokwanira kumanga malo ochitirako misonkhano yatsopano. Mayi wachumayo anagunda chowerengeracho naseka kuti: “Bizinesi imeneyi ndi yopindulitsa kwambiri kuposa kubwereketsa ngongole!”

Kuchita bwino kwa kupanga kumakhala kosangalatsa mobisa. Malinga ndi miyeso yeniyeni ya mzere wopanga makina ku Tianjin, nthawi yochiritsa yazinthu zophatikizika yafupikitsidwa ndi 40%. Woyang’anira malo ochitira msonkhanowo anayang’ana chinsalu chachikulu n’kumenya miyendo yake kuti: “Tsopano kuchuluka kwa zinthu zopangira zinthu kuli ngati kukwera roketi, ndipo makasitomala sachita mantha akamaumiriza anthu kuti agule!”

Masiku ano wobiriwira wa silicon carbide micropowder salinso chinthu chopangidwa mu labotale. Kuchokera pazombo zowuluka m'mlengalenga kupita ku magalimoto amphamvu atsopano omwe akuyenda pansi, kuchokera ku tchipisi ta m'manja tokhala ngati kanjedza mpaka ma turbine atali a mita 100, zili paliponse. Ankhondo akale m'makampaniwa akuti chinthu ichi chapanga dzenje padenga lantchito lazinthu zophatikizika. Malingaliro anga, izi sizongowonjezera zinthu zosavuta, koma "kuwombera m'manja" kwa makampani amakono. Ngati izi zipitilira, ndizotheka kuti tsiku lina matabwa athu odulira adzagwiritsa ntchito ukadaulo wakuda uwu - pambuyo pake, ndani safuna kuti ziwiya zawo zakukhitchini zikhale pamlingo wofanana ndi zida zakuthambo?
