Kusanthula kwamakhalidwe azomwe zimagwiritsa ntchito njerwa zopumira

Mtundu watsopano wa njerwa zotulutsa mpweya wabwino sudzapangitsa kufooka pansi kapena chinthu chosafunikira cha njerwa zoyambilira zopumira chifukwa cha mawonekedwe ake. Njerwa yopumira ikamagwira ntchito ndikutulutsa mpweya wabwino, mpweya wozizira umasunthira pakhotopo kuti mupange kutentha kwakukulu, ndipo zina mwazovuta zomwe zimachitika zimayikidwa pafupi ndi malo, makamaka kupsinjika kwakanthawi kotulutsa mpweya kwa chokulirapo, ndikupangitsa kuti gawo lidasinthike panthawi yogwiritsira ntchito, zomwe zimapangitsa kuti chitsulo chosungunuka chilowemo mosavuta ndikudula kuti chikhale chosavomerezeka kapena chosafunikira. Kuphatikiza apo, ngati valavu yapansi itatsekedwa mwachangu kumapeto kwa chimbudzi, chitsulo chosungunulacho chimalowa mchimake mopanikizika, chifukwa chake ndikofunikira kukhazikitsa valavu yoyimitsa yotsalira pa payipi yolira ya argon.

Chifukwa chake, njerwa zodulira mpweya zovomerezeka zimayenera kukhala ndi mawonekedwe oyenera komanso okhazikika a njira yolumikizirana ndi zida ndi kukhazikika kwamatenthedwe kuti muchepetse chitsulo. Msewu wopitilira mpweya wa njerwa zotulutsa mpweya wabwino ndi kuchuluka kwa ma pores olumikizidwa omwazika mu thupi la njerwa (monga zikuwonetsedwa pa Chithunzi 2). Njira zazing’onoting’ono za micronzi zimapanga kukana kwakukulu kwa chitsulo chosungunuka, ndipo sizolowera kwenikweni. , Thovu la mpweya lomwe limapangidwa ndi njerwa zotulutsa mpweya ndizochepa, yunifolomu komanso yolimba, ndikosavuta kusunthira chitsulo chosungunuka kutentha, ndipo ndikosavuta kulimbikitsa kuyandama kwa inclusions kuti ikwaniritse bwino.

Njerwa yatsopano yolowetsa mpweya sikophweka kuyambitsa gawo la njerwa. Mukamawombera argon, malo otulutsira njerwa yomwe imatha kupopera mpweya imakhudzidwa mwachindunji ndi chitsulo chosungunuka kwambiri ndipo mpweya wozizira umayenda mosalekeza, zomwe zimapangitsa kutentha kwakukulu. Kupsyinjika kwa mpweya pamalo omwe amapangira chidutswacho ndichachikulu kwambiri. Munthawi imeneyi, kutentha kwazizira komanso kuzizira kumapangitsa kuduladula pafupi ndi malo otulutsira mpweya, zomwe zimapangitsa kuti mtengowo usunthike ndikupangitsa kuti pansi usawonongeke. Kupsyinjika kwamphamvu komwe kumadza chifukwa chakuchepa kwa voliyumu yama voliyumu komanso kukulira kwa volumetric kwa magawo ena kumatha kupanga njerwa yolumikizidwa ndi mpweya kuti ipange gawo limodzi, lomwe limapereka zofunikira zakutsogolo kwa kukana kwamphamvu kwa zinthu zosatsutsika. Komabe, pali mayendedwe amagetsi a micron pamalo onse ogwirira ntchito njerwa zopumira, ndipo magwiridwe antchito otentha ndi ochepa, kotero kuti njerwa zatsopano zomwe zimatulutsa mpweya sizivuta kupanga gawo loyambira la njerwa.
