Chiedza Weight Clay Insulation Brick inogadzirwa nemoto ivhu grog seyakagadzirwa uye ivhu repurasitiki seanosunga mumiririri wobva wawedzera yakakodzera inopisa kana kupupa mumiririri kuburikidza nekupfura. Ivhu rekudzivirira rinovharira zvinooneka porosity yakakwira inosvika 40 ~ 85% uye huwandu hwehuwandu hwakaderera pane 1.5 g/cm3. Clay insulation zvidhinha zvemoto zvinonyanya kushandiswa semidziyo yekudzivirira muchoto yeindasitiri kuderedza kupisa kwekupisa, kuchengetedza simba uye kurerutsa mhando yemidziyo inopisa.
Light Weight Clay Insulation Brick inogadzirwa kubva kune yakakwira kuchena moto ivhu uye binder, nekunyudza kuburikidza nekushisa kwakanyanya. clay insulation blocks inodhura yakaderera refractory insulation zvidhinha zvine basa repamusoro. Mabhenefiti makuru evhu rekuvharisa block akakwira refractoriness pasi pemutoro, yakaderera mutsara wekuwedzera coefficients, yakanaka yekupisa kutyisa kuramba uye kugona kwakasimba kurwisa kukukurwa. Iyo inogadzirwa neyenzvimbo yepamusoro giredhi fireclay zvinhu pasi pekupisa kwepamusoro zvichienderana neyakagadzika yenyika chiyero, iyo ine kunyange kuwanda density, kusimba kwepamusoro, kuderera kwekushisa conductivity uye kuderera kwakaderera.
Clay insulation firebrick ndeye argillaceous chigadzirwa chine 30 ~ 40% Al2O3 zvemukati. iyo yakagadzirwa ne50% ivhu rakapfava uye 50% yakaoma chamotte maererano neimwe granularity inoda kusanganiswa uye kupiswa pa1300 ~ 1400 ℃ tembiricha yakakwira mushure mekuumbwa nekuoma. Clay insulation moto zvidhinha chikuru chicherwa kuumbwa kunosanganisira kaolinite (Al2O3 · 2SiO2 · 2H2O) uye 6 ~ 7% tsvina (K, Na, Ca, Ti, Fe oxide).

Clay insulation block inonyanya kushandiswa kune insulating lining yenzvimbo dzinopisa kana kutsigira kupisa kunomisa zvidimbu zvezvimwe zvinoramba. Iwo refractory linings kana kupisa insulating zvinhu zvemaindasitiri, senge, ethylene pyrolysis furnaces, tubular mavira, anogadziridza mavira e synthetic ammonia, gasi jenareta uye yakanyanya tembiricha shullte kilns, nezvimwe.
