Ndi matani a njerwa zaku China zokanira

China ndiye gawo lalikulu lopangira zida zokanira, ndipo pali makampani ambiri okanira ku China. Chifukwa chake, kuchuluka kwa njerwa zaku China zomwe zimawononga ndalama pa tani zakhala funso lodetsa nkhawa kwambiri kwa aliyense. Chimene Luoyang Songdao akufuna kukuuzani apa ndikuti chifukwa cha zipangizo zambiri ndi mitundu ya njerwa zosakanizika, mitengo ya njerwa zokanira ndi yosiyana. Muyenera kusankha mosamala njerwa zokanira zoyenera kwa inu molingana ndi magawo omwe mumagwiritsa ntchito njerwa za refractory, ndiyeno funsani opanga njerwa za refractory pamtengo wa njerwa zotsutsa.

Njerwa zomangira zimatchedwa njerwa zamoto. Refractory yopangidwa ndi dongo losagwira moto kapena zinthu zina zosagwirizana. Wotumbululuka wachikasu kapena wofiirira. Amagwiritsidwa ntchito pomanga ng’anjo yosungunuka, ndipo amatha kupirira kutentha kwa 1580 ℃-1770 ℃. Amatchedwanso firebrick. A refractory zinthu ndi mawonekedwe ndi kukula kwake. Malinga ndi ndondomeko yokonzekera, ikhoza kugawidwa mu njerwa zowotchedwa, njerwa zosawotchedwa, njerwa zosakanikirana (njerwa zosakanikirana), njerwa zokanira ndi kutentha; malinga ndi mawonekedwe ndi kukula kwake, akhoza kugawidwa mu njerwa muyezo, njerwa wamba, njerwa wapadera woboola pakati, ndi zina zotero. kusintha kwa thupi ndi mankhwala ndi zotsatira zamakina pa kutentha kwakukulu. Mwachitsanzo, njerwa zadongo zokana, njerwa zazikulu za alumina, njerwa za silika, njerwa za magnesia, ndi zina zambiri.
