From which can be seen the quality of rock wool insulation board - Huaqiang Electronic Network

The ordinary thermal insulation wall generally has four parts, which are composed of a wall structure layer, a wall insulation layer, a wall protection layer and a veneer layer, and the rock wool insulation board is added inside the wall insulation layer. It can help the wall to play the role of thermal insulation. It can be said that the effect of a wall insulation is mainly to see if the quality of the wall insulation is clear, that is, whether the quality of the rock insulation board can meet this demand. .

The insulation layer and the other three layers are connected by four methods: connecting rod bracket, oblique connecting rod bracket, long screw and bonding agent. The above four connection methods have their own advantages. After long-term comparison, we can find out. These have a lot to do with the durability and insulation strength of our external wall insulation. The technicians of the following North American New Insulation Materials Co., Ltd. will help you analyze them through examples.

First, the rock wool insulation board and the insulation layer are bonded by various adhesives. If the adhesive between the two layers is not evenly applied during this period, the rock wool insulation board and the insulation layer will take a long time to occur. The phenomenon of shedding, but this is also related to the quality of the adhesive. The use of the product with expired quality will not only affect the quality of the rock wool insulation board, but also will not have a good bonding effect. When choosing a product with quality assurance. The products connected by the long screw should pay attention to the position of the eye. The position of the eye should be selected in a flat place. Do not choose the uneven place, because it is easy to damage the overall quality of the outer wall, and the place where the screw is connected in the uneven place. It is not very strong, and it is easy to fall off due to the damage of external force, and the product that has fallen off cannot be used twice.

External wall rock wool insulation board specifications

The rock wool insulation board mainly plays an important role in the thermal insulation of the external thermal insulation system of the building, and the main reason for its insulation is the system structure of the external thermal insulation system. Surface glue: It is a polymer cement mortar made of high molecular polymer, cement, sand and filler as the main material, with certain deformation ability and good bonding performance. The rock wool board plays an important role in the thermal insulation of the external thermal insulation system of the building, and the main reason for its insulation is the system structure of the external thermal insulation system. The rock wool board is composed of a thermal insulation layer of a rock wool board material, a surface layer (a full-layer reinforcing mesh in the plastering paste), a fixed layer (adhesive, anchor), a facing layer, and a non-load-bearing thermal insulation structure fixed on the outer surface of the outer wall. . The outer wall insulation system of rock wool board is mainly composed of veneer layer, external wall thermal insulation fire barrier, base layer, insulation layer and plaster layer.

The rock wool products produced by Hebei Meizhou New Insulation Materials Co., Ltd. basically indicate that the rock wool is made of selected basalt as the main raw material, and the artificial inorganic fiber is processed by high temperature melting. It has the characteristics of light weight, small thermal conductivity, good sound absorption performance, non-combustible and good chemical stability. Insulation rock wool board wall insulation rock wool board, external wall insulation rock wool board is a new type of insulation, flame insulation and sound absorption material. In addition to the characteristics of rock wool in general, rock wool products also have the properties of waterproof, heat preservation, heat insulation and cold insulation. They have certain chemical stability and will not deliquesce even in long-term use under humid conditions. According to the JISA9512-1979 method test, the water-repellent rate is above 98. Since the product does not contain fluorine (F-) or chlorine (Cl-), it has no corrosive effect on the equipment. It was inspected as non-combustible material by the Tianjin Fire Research Institute of the Ministry of Public Security.

Fireproof rock wool board basalt and other natural ore are the main raw materials, which are made by high temperature melting into fiber, adding appropriate amount of binder, solidification processing, widely used in shipbuilding, metallurgy, electric power, construction and other industries, with good thermal insulation. Sound insulation effect. Convenient construction and installation, remarkable energy saving effect, high performance and price ratio.

Pay attention to the following points when constructing rock wool insulation board:

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. 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. The 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 insulation object is placed vertically and has a considerable 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.

The above is sorted by the technical staff of River North America New Insulation Materials Co., Ltd., the price of rock wool insulation board is welcome to inquire.
