Kugwiritsa ntchito kofunikira kwa silicon carbide yopangidwa ndi reaction-sintered ndi mawonekedwe a mphete zotsekera

Silicon nitride (SiC) ndi mchenga wa quartz, coke ya petroleum yokhala ndi calcined (kapena coking ya malasha), slag yamatabwa (kupanga silicon nitride yobiriwira kumafunika kuwonjezera mchere) ndi zinthu zina zopangira, kudzera mu ng'anjo yamagetsi yotenthetsera kutentha kosalekeza. Mphete yotsekera ya Silicon nitride ndi chinthu cha silicon nitride chopangidwa ndi zinthu za silicon carbide. Ndiye kodi kugwiritsa ntchito silicon carbide yopangidwa ndi reaction-sintered ndi makhalidwe a zisindikizo ndi kotani?

Kugwiritsa ntchito silicon carbide yofunika kwambiri pochita zinthu zotsutsana ndi kuzizira:

1. Kugwiritsa ntchito zinthu zachitsulo m'makampani kumagwiritsa ntchito kukana kutentha kwa silicon nitride, mphamvu zambiri, kutentha bwino, kukana kukhudza, kukana kutentha kosalekeza, monga ng'anjo yogawa thanki. Thireyi ya ng'anjo yokonzanso, selo ya aluminiyamu ya electrolytic, chingwe cha ng'anjo yosungunuka yamkuwa, arc ya ng'anjo ya zinc powder, chubu choteteza thermocouple, ndi zina zotero.

2. Kugwiritsa ntchito kwa makampani opanga zitsulo kumagwiritsa ntchito silicon nitride yodulidwa. Kukana kutentha, kukana kukwawa. Chifukwa cha kutentha kwake, imagwiritsidwa ntchito popangira chitsulo chachikulu ndi chapakati kuti chikhale ndi moyo wautali.

3. Makampani opanga zitsulo amagwiritsa ntchito silicon nitride. Mphamvu yake ndi yachiwiri kuposa chitsulo chagolide, mphamvu yake ndi yolimba, mphamvu yake ndi yolimba, mphamvu yake ndi yolimba, mphamvu yake ndi yolimba, mphamvu yake ndi yolimba, mphamvu yake ndi yolimba, mphamvu yake ndi yolimba, mphamvu yake ndi yolimba, mphamvu yake ndi yolimba, mphamvu yake ndi yolimba, mphamvu yake ndi yolimba, mphamvu yake ndi yolimba, mphamvu yake ndi yolimba, mphamvu yake ndi yolimba, mphamvu yake ndi yolimba. Mphamvu yake ndi yolimba ndi yolimba nthawi 5 mpaka 20, ndipo ndi imodzi mwa zipangizo zabwino kwambiri zogwiritsira ntchito mabwalo amasewera a ndege.

4. Kugwiritsa ntchito mphamvu ya kutentha pakupanga zinthu zokongoletsera za porcelain ndi zidutswa za mchenga. Makhalidwe a kutentha kowala komanso kutentha kwambiri, kupanga ndi kupanga uvuni wachitsulo sikungochepetsa kuchuluka kwa uvuni, komanso kupititsa patsogolo kuchuluka kwa zinthu zomwe zili mu uvuni, ndikuchepetsa nthawi yopangira, yomwe ndi chinthu choyenera kwambiri chopangira utoto wa ceramic.

5. Kugwiritsa ntchito chitetezo cha chilengedwe komanso mphamvu zosunga mphamvu kumakhala ndi mphamvu yabwino yoyendetsera kutentha komanso kukana kutentha, ndipo chosinthira kutentha chimasunga 20%, kugwiritsa ntchito mafuta 20%, kugwiritsa ntchito mafuta 35%, ndipo mphamvu yopangira imawonjezeka ndi 20-30%. Makamaka, kukana kuwonongeka kwa chitoliro chotulutsira madzi chomwe chimagwiritsidwa ntchito mufakitale yopangira migodi ndi kuwirikiza ka 6 mpaka 7 kuposa zida wamba zopangidwa ndi chitsulo.

Mbali za mphete yosindikizira ya silicon carbide yokhala ndi reaction-sintered:

1, kukana kutentha

Chifukwa cha makhalidwe a zinthu za silicon nitride, zisindikizo za silicon nitride zimakhala ndi kukana kutentha kwambiri, ndipo njira zosiyanasiyana zimakhala ndi mitundu yosiyanasiyana ya kukana kutentha. Zisindikizo za silicon nitride zosinthidwa ndi reaction-sintered zitha kugwiritsidwa ntchito kuchokera madigiri 1300, ndipo zisindikizo za silicon nitride zosakakamizidwa zimatha kufika madigiri 1600.

2. Kukana dzimbiri

Mphete yotsekera ya silicon nitride ingagwiritsidwe ntchito kuchokera ku asidi wamphamvu ndi alkali, ndipo zotsatira zake zotsekera sizophweka kuchepetsa.

3, kukana kuvala

Mphete zosindikizira za silicon carbide zopangidwa ndi reaction-sintered motsatira njira inayake yolembera makadi, kotero kuti dongosololi likhale lolondola kwambiri komanso losalala, limodzi ndi kukana kwa zinthu za silicon carbide, mphete zosindikizira za silicon nitride zitha kugwiritsidwa ntchito kukandana. Makhalidwe opitilira kutentha kwambiri sachepetsa mosavuta mawonekedwe a kuwonongeka.

4. Kusinthasintha

Reactivity silikoni carbide zopangira malinga ngati pali ukadaulo winawake wopangira, zitha kusinthidwa kukhala mitundu yosiyanasiyana ya ubweya wosanjikiza, processing yachiwiri, kuti ogula azifuna katundu.
