Rock wool board is a kind of selected basalt and other natural ores as the main raw materials. The price of rock wool board is not high. Rock wool heat insulation board melts into fibers at high temperature, adds a proper amount of adhesive, and then solidifies and processes. Made of. The red brick tunnel kiln series of refractory and thermal insulation products independently produced and researched by our company have realized the unified one-stop purchase for our customers. Fire resistant products: various specifications of high aluminum refractory brick, clay refractory brick, high temperature water glass, asbestos board, asbestos powder, asbestos wool, asbestos rope, kiln brick, boiler refractory brick, high aluminum poly light ceiling brick, mullite ceiling brick, Drawings and processing of high strength insulating brick, diatomite insulating brick, mullite insulating brick, aluminum silicate fiber products, rock wool, rock wool pipe, perlite, ver stone powder, castable, high aluminum cement, refractory mud, high aluminum fine powder, high aluminum aggregate, quartz powder, quartz sand, various boiler doors, grate, various shapes of refractory brick.

The insulation performance of rock wool insulation board has been very good, especially at room temperature, its insulation performance is much better than other insulation boards. In addition, the sound insulation effect of rock wool is quite good. However, please pay attention to the following points when constructing rock wool heat shield:

1. Rock wool board is used for cold storage. Damp proof course shall be added to the cold surface. At low temperature, it is insulated with resin free rock wool, and its moisture-proof layer must also be fireproof.

2. In order to reduce heat loss of rock wool board, all joints of board and felt must be closely connected. When multi-layer insulation is used, the cross joints shall be staggered to avoid the formation of thermal bridge, and the cold state shall be maintained during the cold insulation process. Bridge.

3. Rock wool board products are used for outdoor heat insulation or places where metal or plastic coating is prone to mechanical wear, and attention shall be paid to joints, joints and seals. If necessary, glue shall be added for sealing, and the overlap of the coating shall not be less than 100mm

4. The rock wool board needs to be insulated and the pipeline should be free of leakage. The surface is dry, free of grease and rust. Under the condition of orange Mandarin, in order to promote corrosion protection, appropriate coating can be used.

5. When the insulation is placed vertically and has a certain height, the insulation layer shall be provided with locating pins or support rings, with a spacing of no more than 3m, so as to prevent the insulation material from sliding downward with the insulation layer. Vibration.

6. For the insulation of rock wool board products with large diameter or flat wall equipment, when the temperature exceeds 200 ° C, insulation nails shall be added and the external protection shall be tight.

7. When the temperature of rock wool board exceeds 200 ° C, the insulating material shall be properly protected to prevent possible expansion from changing the thickness and bulk density.

8. It is not suitable to carry out outdoor heat preservation and cold insulation construction in rainy days, otherwise, rainproof measures shall be taken.
