1. Menene yashi yumbu?
Yashi yumbu an yi shi ne da ma'adanai masu ɗauke da Al2O3 da SiO2 kuma an ƙara shi da sauran kayan ma'adinai. Yashi mai siffar zobe wanda aka yi ta foda, pelletizing, sintering da matakan ƙima. Its main crystal tsarin ne Mullite da Corundum, tare da taso keya hatsi siffar, high refractoriness, mai kyau thermochemical kwanciyar hankali, low thermal fadada, tasiri da kuma abrasion juriya, fasali na karfi fragmentation. Za a iya amfani da yashi yumbu don samar da simintin gyare-gyare masu inganci ta kowane nau'in aikin simintin yashi.
2. Yankin aikace-aikace na yashi yumbu
Yashi yumbu an yi amfani da shi sosai a cikin kafuwar mafi yawan nau'ikan fasahohin da aka samo asali, kamar yashi mai rufin guduro, tsari mai taurin kai (F NB, APNB da Pep-set), akwatin sanyi, akwatin zafi, yashi bugu na 3D, da kuma asarar kumfa. .
3. Ƙayyadaddun yashi yumbu
SND na iya samar da yashi yumbu na ƙayyadaddun bayanai daban-daban. Don abun da ke tattare da sinadarai, akwai babban aluminum-oxide, matsakaicin yashi-yashi-aluminum-oxide da ƙananan yashi na aluminum-oxide, waɗanda ke amfani da kayan simintin daban-daban. Duk suna da yadu jeri barbashi size rarraba don gamsar abokin ciniki ta buƙatun.
