Silicon carbide (SiC) ƙona nozzles
A cikin matakan zafi mai zafi inda sarrafa ruwa, juriya na yashwa, da kwanciyar hankali na thermal ke da mahimmanci,silicon carbide (SiC) nozzlestsaya a matsayin abin al'ajabi na injiniya. Ba kamar nau'ikan yumbu ko bututun ƙarfe ba, ƙayyadaddun kaddarorin SiC suna magance ƙalubale a cikin konewa, haɓakawa, da tsarin feshin masana'antu. Wannan labarin yana bincika dalilin da yasa masana'antu ke ƙara ɗaukar nozzles na SiC don canza aikin aiki a cikin mafi yawan aikace-aikacen da ake buƙata.

SiC nozzles sun yi fice wajen sarrafa babban saurin gudu, ruwan zafi da iskar gas:
(1) Juriya na Rushewa: Jure ɓoyayyiyar ɓarna a cikin injectors na kwal slurry, tsarin fashewar yashi, ko masu roka ba tare da nakasar da ta haifar da lalacewa ba.
(2) Tsirawar Shock na thermal: Saurin zagayowar tsakanin matsananciyar yanayin zafi (misali allurar mai a cikin tanderu na ƙarfe) ba tare da fashewa ba, godiya ga ƙarancin haɓakar zafin jiki na SiC.
(3) Rashin Ƙarƙashin Sinadarai: Hana lalata daga feshin acidic/alkaline, narkakken gishiri, ko harshen wuta mai oxidizing, yana tabbatar da daidaitaccen lissafi na asali.
2. Madaidaicin Gudanar da Gudanar da Mahimmancin Tsari
A cikin aikace-aikacen da ke buƙatar daidaiton matakin micron, SiC nozzles suna ba da amincin da bai dace ba:
（1）Stable Orifice Geometry: Kula da madaidaicin madaidaicin adadin kwararar ruwa da tsarin feshi koda bayan tsayin daka zuwa yanayin 1500°C+, sabanin karafa da ke jujjuyawa ko yumbu da ke raguwa.
(2) Rage Rufewa: Ƙarfin daɗaɗɗen shimfidar wuri yana rage yawan haɓaka kayan aiki a cikin allurar mai ko tsarin feshin sinadarai.
(3) Haƙuri Haƙuri: Tsare matsi na hydraulic fiye da 500 MPa, manufa don yankan ruwa ko motsin sararin samaniya.
3. Bada Ƙarfafa Ƙarfafa Ƙarfafawa
SiC nozzles suna da mahimmanci a haɓaka tsarin konewa mai ƙarfi:
(1) Wutar Lantarki: Ƙirar da ke jure zafi tana tabbatar da haɗaɗɗun iskar man fetur a cikin injin turbin gas ko masu kona masana'antu, rage wuraren zafi da hayaƙin NOx.
(2) Sassauci mai: Mai jituwa tare da hydrogen, biofuels, ko mai mai nauyi, yana tallafawa canji zuwa tushen makamashi mai dorewa.
(3) Ingantaccen zafi: Rage asarar zafi ta bangon saboda girman ƙarfin zafin jiki na SiC, haɓaka ingantaccen ɗakin konewa har zuwa 15%.
Shandong Zhongpeng Special Ceramics Co., Ltd yana daya daga cikin manyan sabbin kayan yumbu na silicon carbide a cikin kasar Sin. SiC fasaha yumbura: Moh's taurin ne 9 (New Moh ta taurin ne 13), tare da m juriya ga yashewa da lalata, m abrasion - juriya da anti-oxidation. Rayuwar sabis na samfurin SiC shine sau 4 zuwa 5 fiye da 92% kayan alumina. MOR na RBSiC shine sau 5 zuwa 7 na SNBSC, ana iya amfani dashi don ƙarin sifofi masu rikitarwa.
