Mullite stone is a kind of high temperature lightweight aggregate using natural bauxite as raw material.
一, Features
1.Mullite has high temperature and can be directly used as working lining by flame to realize high temperature energy saving.
2. Mullite has low thermal conductivity, good thermal insulation performance, lightweight mullite aggregate, high volume, high strength and air tight structure.
3. The weight of mullite structure is reduced by 40-60%, and the hanging brick on the top of furnace is broken.
4. Mullite can quickly dry the furnace, the high air gap rate can exhaust smoothly, shorten the drying period, and the economic benefits are remarkable. Notice on strengthening sludge pollution in urban sewage treatment plants, notice on Further Strengthening sludge treatment and disposal, organizing and implementing demonstration projects, and notice on strengthening the verification and accounting of sludge treatment and disposal emission reduction in urban sewage treatment facilities... One policy and one law were implemented
二. Application range: working lining of various flame furnaces, direct flame (non melt), heat insulation of other high-temperature equipment, such as:
1. Preparation of various light fire-resistant castables, spray coating, etc;
2. Furnace top and wall of heating furnace, soaking furnace, heat treatment furnace, annealing furnace, ceramic and refractory firing furnace.
3. Steam boiler, oil industry tubular heating furnace, cracking furnace lining.
4. All kinds of industrial furnace door, observation hole lining. Although many voices have pointed out that the "false fire" in the sludge treatment market is too prosperous, it is impossible to deny that the background of policy support has brought benefits to the industrial development. It is also necessary to carefully examine the technological change, which has brought a driving force that can not be ignored to accelerate the sludge treatment industry into the right track.
The physical and chemical properties of lightweight mullite aggregate are 0mpa. For environmental protection enterprises, this may convey: in the period of rapid change, returning to the nature of the industry will become the direction of environmental protection enterprises in 2019. In other words, under the premise of conforming to the general trend of environmental protection development, we should carefully monitor the market trend, take root in technology and innovation.
