Plaster castable is a kind of refractory plastic material. Through the smoothing or rounding process of the surface, the surface of the thermal insulation structure of the tank equipment is smooth and flat, and the edges and corners are clear; the surface of the pipeline insulation structure can be flat, smooth, well-proportioned and outer diameter. be consistent.
Plaster Castable Features
The thermal conductivity is low and the energy saving effect is remarkable. Especially in the higher temperature range, its thermal conductivity and thermal stability are significantly higher than other thermal insulation materials. Moreover, it has simple and fast construction, natural condensation under normal temperature (10-25 degrees Celsius), no need for heating and other auxiliary conditions, and has the characteristics of heat preservation, heat insulation, high temperature resistance and strong plasticity, which can solve the problem of large temperature range, large vibration and maintenance. Thermal insulation of large-scale shaped equipment with large difficulty and complicated shape.
When the plaster is applied, stir the product evenly, but prevent it from thickening after a long time. When it is applied in the cold state, it can be directly applied. When the insulation layer is under heat, the smear plaster can be applied to the surface of the smear. After the plum blossoms are solidified, the whole area is smeared in a large area, and the action should be light when applied. Vertical and horizontal cross-layering is carried out to enhance the inter-fiber tensile force, and the thickness of each layer depends on the specific conditions. Generally, after the first layer is dried, after the second layer, the third layer, and the like are consolidated, the surface is collected, dried, and then subjected to surface layer treatment.
Plaster Castable
It is the insulation and winding insulation of rigid insulation products in equipment or pipelines. Due to various factors, the surface of the insulation layer is uneven, which affects the construction of the metal casing or the protective layer of the wrapped glass cloth.
The plaster castable for power plant boilers is a finishing project carried out on the outer surface of the tank of equipment. After all kinds of insulation construction, the main function is to carry out outer layer protection, which plays the role of heat preservation, heat insulation and fire prevention.
