The national standard density of ceramic fiber modules is 220Kg/m³, which is determined by the following two aspects.
1. Mar is eol dúinn go léir, tagann feidhmíocht inslithe teirmeach maith snáithín ceirmeach as a seoltacht íseal teirmeach. Laghdaíonn seoltacht theirmeach an mhodúil snáithíní ceirmeacha le méadú ar an dlús mórchóir, ach laghdaítear méid an laghdaithe de réir a chéile. Nuair a sháraíonn an dlús 300KG/M3, ní laghdaíonn an seoltacht theirmeach a thuilleadh agus is gnách go n-ardóidh sé.
2. However, the density limit of the ceramic fiber module is 240Kg/m³; this is because the ceramic fiber blanket is made of fiber cotton with a double-roll spinning process. The length of the fiber cotton is between 80-130 mm. Once it exceeds 240Kg/m³ At this limit density, the fibers will break a lot, and the breaking rate is as high as 48 percent , thus affecting the product performance.
In practical applications, the density of the ceramic fiber module should be comprehensively considered according to the furnace type, temperature, combustion medium, and temperature rise requirements of the heat treatment furnace, but a reasonable density should be between 200-240Kg/m³, preferably 220Kg/m³ .
