Hard rock wool board price @æ–°é—»ä¸å¿ƒDirector in charge of telephone fax [Note]: This number is only for customers, declined all activities and sales, rock wool board is selected high quality basalt as the main raw material, after melting at high temperature, The international advanced four-roll centrifugal cotton process, the basalt cotton high temperature solution is pulled into 4~7μm discontinuous fiber, and then a certain amount of binder, dustproof oil, water repellent agent is added to the rock wool fiber. Settlement, solidification, cutting and other work processes, according to different purposes to produce a series of products of different densities. Application range Petrochemical industry - insulation, insulation, sound absorption and noise reduction of equipment in petroleum, electric power and chemical industry.
Construction industry - insulation insulation, sound absorption and noise reduction for building partitions, curtain walls, roofs and enclosures.

Rockwool board moisture absorption rate: 3.9 (%) rock wool board is made of basalt and other natural ore as the main raw material, melted into fiber by high temperature, added with appropriate amount of binder, solidified and processed, widely used in ships, metallurgy , power, construction and other industries, with good insulation and sound insulation. Convenient construction and installation, remarkable energy saving effect, high performance and price ratio.
Marine and hydrophobic rock wool insulation boards are added with hydrophobic additives during production, which have good moisture resistance. Marine rock wool board is used for ship thermal insulation and fireproof partition; hydrophobic rock wool board is used for vehicles, mobile equipment, cold storage engineering, air conditioning ducts, and thermal insulation in humid environments and applications where moisture is required. The rock wool board for construction has excellent fireproof, thermal insulation and sound absorbing properties. It is mainly used for thermal insulation of building walls and roofs; fire protection and noise reduction of building partitions, firewalls, fire doors and elevator shafts. The thermal insulation performance of rock wool insulation board has always been very good, especially in the case of normal temperature, its thermal insulation performance is much better than other insulation boards. In addition, the sound insulation effect of rock wool is also quite good, and it is widely used in Europe and North America. However, pay attention to the following points when constructing rock wool insulation boards:
1. The rock wool board needs to be insulated and the pipeline should be free from any leakage. The surface is dry, free from grease and rust. Under the conditions of orange mandarin, in order to facilitate corrosion protection, appropriate coating can be adopted.
2. Rock wool board In order to achieve the minimum heat loss, all the joints of the board and the felt 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, which must be kept cold during cold preservation. bridge.
3 Rock wool board products are 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, add glue seals, the overlap of the wrap layer is not less than 100mm.
4. Rock wool board is used for cold preservation. It must be added with moisture-proof layer on the cold surface. In the case of extremely low temperature, it is insulated with resin-free rock wool, and its moisture-proof layer must also be fireproof.
5. When the rock wool board temperature exceeds 200 °C, the insulation must be properly protected, so that the possible expansion will not change the thickness and bulk density.
6. For the insulation of rock wool board products for large diameter or flat wall equipment, insulation nails should be added when the temperature exceeds 200 °C, and the outer protection should be tight.
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.
If the sloppy treatment of rock wool board, it is likely to lead to the use of rock wool but it does not work.
Color steel rock wool board sandwich composite board:
It is a new building material with colored rock wool board as the surface layer, rock wool, fireproof and flame retardant insulation material as the core layer. The utility model has the advantages of light weight, good heat insulation, good sound absorption and sealing, convenient construction, short cycle, low comprehensive cost, bending resistance, corrosion, and beautiful appearance.
Rock wool board quality characteristics:
(1) Thermal insulation, thermal conductivity: 0.035W/M 2 K.
(2) High strength, can be used as a retaining structure, load-bearing structure, bending and compression resistance, general houses do not use beams and columns.
(3) Bright color, no need for surface decoration.
(4) Flexible and quick installation, the construction period can be shortened by more than 40%
It is widely used in the ceiling and partition of roofs, walls and air clean rooms of steel structure workshops and simple movable houses.
