Introduction to size specifications of PLUS blanket insulation material ceramic fiber blanket in the cement industry

Release Time: 2026-05-13

What are the size specifications of PLUS blanket insulation material ceramic fiber blanket in the cement industry? PLUS blanket is a new type of insulation blanket launched by Rosewool Insulation Refractory Co.,Ltd. for steam turbines. It is made from selected hot materials such as coke gemstones, melted at high temperature, blown into fibers, cured and formed, and cut and rolled. It has the characteristics of high temperature resistance, good stability, high chemical stability, low thermal conductivity, low heat capacity, and easy cutting and construction. Compared with natural aluminum silicate needle punched blanket, it has lower slag ball content, higher tensile strength, better rebound rate, no burrs in cutting, convenient construction, better insulation effect, and longer service life.

The mainstream specifications for PLUS blanket (ceramic fiber needle punched blanket) used in the cement industry are 7200mm long, 610mm wide, and 20-50mm thick, with a standard bulk density of 128kg/m ³ and a temperature resistance of 1260-1430 ℃. It is suitable for insulation of rotary kilns, preheaters, pipelines, and furnace doors. PLUS blanket, based on traditional ceramic fiber blanket, has achieved comprehensive breakthroughs in core indicators such as tensile strength, slag ball content, and thermal conductivity by optimizing the fiber matrix and double-sided needle punching process;

The unique advantages of PLUS blanket:
1. Significant improvement in tensile strength
2. The content of slag balls has decreased by nearly 50%
3. Lower thermal conductivity
4. Rebound rate ≥ 85%
