Silicon nitride (SiC) ndi quartz mchenga, calcined petroleum coke (kapena malasha coking), nkhuni slag (kupanga wobiriwira pakachitsulo nitride ayenera kuwonjezera mchere) ndi zipangizo zina, kupyolera mu ng'anjo magetsi Kutentha mosalekeza mkulu kutentha smelter. Silicon nitride yosindikiza mphete ndi silicon nitride yopangidwa ndi silicon carbide material. Ndiye ntchito zofunika kwambiri za reaction-sintered silicon carbide ndi mawonekedwe a zisindikizo ndi ziti?
Ntchito yofunika kwambiri ya reaction sintering silicon carbide:
1. Kugwiritsa ntchito makampani opanga zitsulo ndikugwiritsa ntchito silicon nitride kutentha kukana, kulimba kwambiri, kukhathamiritsa kwamafuta abwino, kukana mphamvu, kutentha kosalekeza kopitilira muyeso kosalunjika zopangira, monga ng'anjo yogawa matanki. thireyi yowotchera ng'anjo, aluminiyumu electrolytic cell, ng'anjo yamkuwa yosungunuka, zinc ufa ng'anjo arc, chubu choteteza thermocouple, ndi zina zambiri.
2. Kugwiritsa ntchito mafakitale azitsulo kumagwiritsira ntchito etching ya silicon nitride. Kukana kutentha kwa kutentha, kukana kwa abrasion. Chifukwa cha matenthedwe ake abwino, amagwiritsidwa ntchito kuyika ng'anjo zazikulu komanso zazikuluzikulu zopangira chitsulo kuti apititse patsogolo moyo wautumiki.
3. Makampani opanga zitsulo zopangira zitsulo amagwiritsa ntchito silicon nitride mphamvu ndi yachiwiri kwa chitsulo chagolide, kukana mwamphamvu kuvala, kukana kuvala mwamphamvu, kukana kwapaipi, centrifugal impeller, chipinda chopopera, makina ozungulira, migodi yabwino yopangira zipangizo, kukana bwino kuvala. Moyo wautumiki wa pulasitiki ndi nthawi 5 mpaka 20, ndipo ndi imodzi mwazinthu zopangira mabwalo amasewera oyendetsa ndege.
4. Kugwiritsa ntchito mphamvu yotengera kutentha m'mafakitale opanga zipangizo zomangira za porcelain ndi zidutswa zamagudumu a mchenga. Makhalidwe a kutentha kwakukulu ndi kutentha kwakukulu kwa kutentha, kupanga ndi kupanga pepala lazitsulo zachitsulo sikungathe kuchepetsa voliyumu ya ng'anjo, komanso kupititsa patsogolo kuchuluka kwa zosungirako ndi khalidwe la mankhwala a ng'anjo, ndi kuchepetsa nthawi yopangira, yomwe ndi yabwino yosalunjika. zinthu zowombera za ceramic pigments.
5. Kugwiritsa ntchito chitetezo cha chilengedwe ndi mphamvu yopulumutsa mphamvu kumakhala ndi kutentha kwabwino komanso kukana kutentha, ndipo chowotcha kutentha chimapulumutsa 20%, kugwiritsa ntchito mafuta 20%, kugwiritsa ntchito mafuta 35%, ndipo kupanga bwino kumawonjezeka ndi 20-30%. Makamaka, kukana kuvala kwa chitoliro chamadzi otulutsa omwe amagwiritsidwa ntchito m'mafakitale opangira migodi ndi nthawi 6 mpaka 7 kuposa zida wamba zachitsulo.
Rection-sintered silicon carbide seal mphete:
1, kukana kutentha
Chifukwa cha mawonekedwe a zida za silicon nitride, zisindikizo za silicon nitride zimakhala ndi kukana kutentha kwambiri, ndipo njira zosiyanasiyana zimakhala ndi mitundu yosiyanasiyana ya kukana kutentha. Reaction-sintered silicon nitride zisindikizo zitha kugwiritsidwa ntchito kuchokera ku madigiri 1300, ndipo zosindikizira zosakanizika za silicon nitride zimatha kufikira madigiri 1600.
2. Kukana dzimbiri
Mphete yosindikiza ya silicon nitride ingagwiritsidwe ntchito kuchokera ku asidi amphamvu ndi chikhalidwe cha alkali, ndipo kusindikiza kwake sikophweka kuchepetsa.
3, kuvala kukana
Rection-sintered silicon carbide seal mphete molingana ndi njira ina ya makhadi, kuti dongosololi likhale lolondola kwambiri komanso losalala, kuphatikiza ndi kukana kwa zida za silicon carbide, mphete zosindikizira za silicon nitride zitha kugwiritsidwa ntchito kusisitana. Makhalidwe a kutentha kosalekeza samachepetsa mosavuta kuwonongeka.
4. Kudumphadumpha
Reactivity sintered pakachitsulo carbide zopangira bola ngati pali luso linalake processing, zikhoza kusandulika zosiyanasiyana za ubweya mluza, processing yachiwiri, kuti ogula akufuna katundu.
