Rock wool insulation board is a fireproof insulation material, which has the characteristics of compressive and tensile strength, low water absorption and moisture absorption, will not cause thermal expansion, and aging resistance. It is compatible with external wall systems and provides effective Insulation, energy saving, fire prevention and other performances. Then, let's introduce the precautions of rock wool insulation board construction and the function of rock wool insulation board.
Matters needing attention in the construction of rock wool insulation board
1. During the construction of the rock wool insulation board, the surface should be kept dry, free of grease, no rust, etc., in order to facilitate anti-corrosion, an appropriate coating can be adopted.
2. For the purpose of minimizing the heat loss of rock wool insulation board, all the joints of the board and the felt must be tightly connected. For the multi-layer insulation, the cross joints should be staggered to avoid the formation of thermal bridges.
3. The rock wool insulation board is used for outdoor insulation or where it is prone to mechanical wear. Metal or plastic wrapping can be used, but pay attention to the sealing of joints and joints. If necessary, add a rubber seal. The overlapping part of the wrapping layer is not less than 100mm .
4. When the rock wool board is kept cold, a moisture-proof layer must be added to the cold-keeping surface. For extremely low temperature, rock wool without resin can be used for heat insulation. The moisture-proof layer must also be fireproof.
5. If the temperature of the rock wool insulation board exceeds 200 ° C, a suitable outer cover must be added so that the resulting expansion will not change the thickness and tolerance.
6. Rock wool insulation board can not be carried out in rainy days during outdoor insulation and cold insulation construction, otherwise rainproof measures shall be taken.
Function of rock wool insulation board
The rock wool insulation board has the advantages of durability, sturdiness, wind resistance, impact resistance, high temperature resistance, corrosion resistance, etc., and can well solve the technical problems of back halogen and frost. In addition, the rock wool insulation board is easy to construct and adopts combined installation. It has excellent characteristics such as nailing, planing, sawing, drilling and sticking. Rock wool insulation board does not need high temperature, no pollution, no harm, no radioactivity in the production process, and belongs to modern green environmental protection new energy-saving building materials.
Selection of rock wool insulation board
With the continuous development of industrialization, rock wool insulation boards are widely used in various industries. The thermal conductivity of rock wool insulation boards is an important indicator to measure the performance of rock wool insulation boards. The smaller its thermal conductivity coefficient, the energy is transferred through the materials. The less the rock wool insulation board, the better the thermal insulation performance. Good quality rock wool insulation board has lower moisture absorption, higher strength and supports gravity.
Application of rock wool insulation board
With the continuous development of economy, the performance of rock wool insulation board is also continuously improved. Rock wool insulation board is widely used. This material has the characteristics of thermal insulation, sound absorption and fire prevention in construction; heat insulation, sound absorption and noise reduction of equipment in the power, petroleum, and chemical industries. Glass magnesium rock wool insulation boards are commonly used for external walls. The surface layer made of special materials is added with fireproof board made of reinforced fiber and mesh cloth, which can be cut arbitrarily.

Rock wool insulation board
The ORP sensor, also known as the ORP electrode, measures the redox ability of water. As an indicator of water quality, ORP sensors are widely used. Daruifuno's digital ORP sensor adopts PPS or stainless steel shell, which is compact and easy to carry. Built-in RS485 digital interface, internal storage of calibration data, plug and play. The split M16 connector is easy to plug and unplug, and the cable length can be customized. The measurement range of ORP is generally -2000~2000mV, the digital ORP sensor has a fast response speed, a large-capacity reference, and a long service life. We have matching digital pH controllers and multi-parameter controllers that can be connected with digital ORP electrodes to realize the functions of display, control and output. The digital ORP sensor can be used for most of the water treatment applications. Such as drinking water, surface water, sewage water, industrial process wastewater and so on. Our company is specialized in water quality analysis instruments for more than 10 years, our main products are online PH ORP Analyzer , Conductivity Analyzer, Dissolved Oxygen Analyzer, Turbidity Analyzer, COD Analyzer , Ammonia Analyzer , chlorine analyzer, etc.
