Kafukufuku pa njira yabwino yowongolera ya reaction-sintered silicon carbide

Sintered silicon carbide ndi chinthu chofunikira kwambiri cha ceramic, chomwe chimagwiritsidwa ntchito kwambiri kutentha kwambiri, kuthamanga kwambiri komanso minda yamphamvu kwambiri. Reaction sintering of sic ndi gawo lofunikira pokonzekera zida za SIC zojambulidwa. Kuwongolera koyenera kwa sintered silicon carbide reaction kungatithandizire kuwongolera bwino momwe zinthu zimachitikira komanso kukonza zinthu.

1. Kukhathamiritsa kwa anachita sintering pakachitsulo carbide zinthu

Zomwe zimachitika ndizofunika kwambiri za sintered silicon carbide reaction, kuphatikiza kutentha kwazomwe zimachitika, kuthamanga kwamachitidwe, chiŵerengero cha reactant misa ndi nthawi yochitira. Pamene optimizing zinthu anachita, m`pofunika kusintha malinga ndi zofunikira ntchito ndi zimagwirira ntchito.

(1) Zomwe kutentha: Kuchita kutentha ndi chimodzi mwazinthu zazikulu zomwe zimakhudza momwe liwiro ndi mtundu wa mankhwala zimachitikira. Mu osiyanasiyana osiyanasiyana, ndi apamwamba anachita kutentha, mofulumira anachita liwiro ndi apamwamba mankhwala khalidwe. Komabe, kutentha kwakukulu kwambiri kumapangitsanso kuwonjezeka kwa pores ndi ming'alu ya mankhwala, zomwe zimakhudza khalidwe la mankhwala.

(2) Zochita kuthamanga: Zomwe zimachitikiranso zimakhala ndi zotsatira pa liwiro la zomwe zimachitika komanso kachulukidwe wazinthu. Mu osiyanasiyana osiyanasiyana, ndi apamwamba anachita kuthamanga, mofulumira anachita liwiro ndi apamwamba mankhwala kachulukidwe. Komabe, kuthamanga kwambiri kungayambitsenso kuwonjezereka kwa pores ndi ming'alu ya mankhwala.

(3) Reactant misa chiŵerengero: The reactant misa chiŵerengero ndi chinthu china chofunika zimakhudza anachita liwiro ndi mankhwala khalidwe. Pamene misa chiŵerengero cha mpweya pakachitsulo ndi yoyenera, mlingo anachita ndi khalidwe mankhwala. Ngati reactant misa chiŵerengero si koyenera, izo zingakhudze anachita liwiro ndi mankhwala khalidwe.

(4) Nthawi yochitira: Nthawi yochitira ndi chimodzi mwazinthu zomwe zimakhudza momwe zimakhalira liwiro komanso mtundu wazinthu. Mkati mwamtundu wina, nthawi yayitali yochitira, imachedwetsa liwiro la zomwe zimachitika komanso mtundu wamankhwala apamwamba. Komabe, nthawi yayitali kwambiri yochitapo kanthu imapangitsanso kuwonjezeka kwa pores ndi ming'alu ya chinthucho, zomwe zimakhudza mtundu wa chinthucho.

2. Reaction-sintering silicon carbide process control

Mu anachita ndondomeko sintered pakachitsulo carbide, m`pofunika kulamulira anachita ndondomeko. Cholinga cha kuwongolera ndikuwonetsetsa kuti zomwe zikuchitika ndikukhazikika komanso mtundu wa mankhwalawo ndi wofanana. Kuwongolera kachitidwe kachitidwe kumaphatikizapo kuwongolera kutentha, kuwongolera kuthamanga, kuwongolera mlengalenga ndi kuwongolera khalidwe la reactant.

(1) Kuwongolera kutentha: Kuwongolera kutentha ndi chimodzi mwazinthu zofunika kwambiri pakuwongolera njira. Kuwongolera kutentha Zomwe kutentha kumayenera kuyendetsedwa ndendende momwe kungathekere kuonetsetsa kuti njira yokhazikika ndi yokhazikika yamankhwala. Pakupanga kwamakono, makina owongolera makompyuta nthawi zambiri amagwiritsidwa ntchito kuwongolera molondola momwe kutentha kumachitikira.

(2) Kuwongolera kukakamiza: Kuwongolera kukakamiza ndi gawo lina lofunikira pakuwongolera njira. Ndi kulamulira zochita kuthamanga, kukhazikika kwa ndondomeko anachita ndi kugwirizana kwa khalidwe mankhwala akhoza kuonetsetsa. Pakupanga kwamakono, makina owongolera makompyuta nthawi zambiri amagwiritsidwa ntchito kuwongolera molondola zomwe zimachitika.

(3) Atmosphere control: Atmosphere control imatanthawuza kugwiritsa ntchito mlengalenga wina (monga mpweya wolowera) mumayendedwe kuti muwongolere zomwe zikuchitika. Ndi kulamulira mlengalenga, n'zotheka kuonetsetsa bata la zochita ndondomeko ndi kusasinthasintha kwa mankhwala khalidwe. Pakupanga kwamakono, mlengalenga nthawi zambiri umayendetsedwa ndi makompyuta.

(4) Reactant khalidwe kulamulira: Reactant khalidwe kulamulira ndi chimodzi mwa zinthu zofunika kuonetsetsa bata la zochita ndondomeko ndi kugwirizana kwa khalidwe mankhwala. Poyang'anira khalidwe la reactants, kukhazikika kwa machitidwe ndi kusasinthasintha kwa khalidwe la mankhwala kungatsimikizidwe. Pakupanga kwamakono, makina owongolera makompyuta nthawi zambiri amagwiritsidwa ntchito kuwongolera zabwino za reactants.

Kuwongolera koyenera kwa reaction-sintered silicon carbide ndiye gawo lofunikira pokonzekera zida zapamwamba za sintered silicon carbide. Ndi optimizing zimene zinthu, kulamulira anachita ndondomeko ndi kuwunika anachita mankhwala, bata la zimene ndondomeko ndi kusasinthasintha kwa mankhwala khalidwe akhoza kuonetsetsa. Pakugwiritsa ntchito, mawonekedwe a sintered silicon carbide amayenera kusinthidwa malinga ndi zochitika zinazake kuti akwaniritse zofunikira zosiyanasiyana.
