Insulation material Glass fiber has always been very good in thermal insulation performance, especially in the case of normal temperature, its thermal insulation performance is much better than other insulation boards. In addition, the fiberglass wool has a very good sound insulation effect and is widely used in Europe and North America. However, pay attention to the following points when constructing the thermal insulation material fiberglass cotton board:
1. Facilities and pipes to be insulated should be free of any leakage, dry surface, no grease, no rust. Under the conditions of orange mandarin, in order to facilitate corrosion protection, appropriate coating can be adopted.
2. In order to achieve the minimum heat loss, all the joints of the fiberglass felt and the board must be very tightly connected. When the multi-layer insulation is used, the cross joints should be staggered to avoid the formation of a thermal bridge. bridge.
3. Glass fiber cotton products should be used for outdoor insulation or metal or plastic foreskin in places prone to mechanical wear, and pay attention to the joints, joints and seals, if necessary, with glue seals, the overlap of the wrap layer is not less than 100mm.
4. For cold preservation, it is necessary to add moisture-proof layer on the cold surface. In the case of extremely low temperature, the glass fiber reinforced cotton sheet without resin is used for heat insulation, and the moisture-proof layer must also be fireproof.
5. When the temperature exceeds 200 ° C, the insulation must be added with appropriate external protection, so that the possible expansion will not change the thickness and bulk density.
6. For the insulation of glass fiber cotton board products for large diameter or flat wall equipment, heat insulation nails should be added when the temperature exceeds 200 °C, and the outer protection should be tightly attached.
7. When the heat preservation object is placed vertically and has a certain height, the insulation layer must have a positioning pin or a support ring, and the spacing should not be more than 3 meters to prevent the insulation material from sliding downward when there is vibration.
8. Outdoor insulation, cold preservation construction should not be carried out on rainy days, otherwise rain protection measures should be taken.
Before the construction, all mechanical equipment must be inspected, debugged and submitted for inspection before it can be used. In the process of use, a special person responsibility system is adopted, and special personnel are required to carry out daily maintenance and maintenance work; safety personnel must be educated during construction. Explain the safety precautions. During construction, all safety rules and regulations and operating procedures must be strictly observed to ensure safe construction; the operation site should be finished and the materials should be transported to the designated place, and should not be dropped from high places; construction materials are required. Do the orderly stacking, keep the site clean and tidy. Seat belts should be fastened when workers are working at heights.
