The new insulation board is made of expanded vermiculite and a certain amount of adhesive, which is made by hot pressing or cold pressing. The board has the characteristics of heat preservation, heat insulation and fire prevention. This product can be used in fire door cores, fireplace linings, wall materials.
Introduction of slate:
Meteorite is a new type of inorganic material. It is made of expanded vermiculite as the main raw material and mixed with a certain proportion of inorganic binder. After a series of processes, it has high temperature resistance, fire resistance, environmental protection, heat insulation, sound insulation and no A board containing harmful substances. After heating at a high temperature to 1200 °C, it does not produce a gas that is harmful to human health, and the combustion performance reaches Grade A.
In China, it is still in its embryonic stage. Domestically, it mainly exports vermiculite raw materials, while finished products are rarely used in China. However, in recent years, domestic market demand has gradually increased. Developed countries such as the United States, Britain, and France have been widely used in the 1980s. Non-combustible, non-melting, high temperature resistance, because the slate is mainly composed of expanded vermiculite, the inorganic material has no carbon and does not burn. Its melting point is 1370 ~ 1400 ° C, the maximum use temperature is 1200 ° C.
The advantages of using the slate as the fire door of the door core are as follows: 1. Flame retardant, heat insulation and high temperature resistance. After a long time of high temperature roasting, its integrity is maintained. 2, environmental protection, because it is composed of inorganic materials, so it does not contain formaldehyde, benzene and other toxic substances, even at high temperatures, it does not release toxic and harmful gases. 3. The slate is a lightweight fireproof material. When it is used as a fireproof door, the weight of the hinge is low, that is, the load of the hinge hinge is low, that is, the wear caused by the use is reduced, the service life of the fire door is prolonged, and the maintenance cost is saved. 4. The wooden fire door made of slate has a smoother surface and no blistering. 5, easy to install. The meteorite fire door can be designed according to the manufacturer's process and trimmed to the required length during installation to facilitate installation. 6. Save factory costs. The use of slate as the door core saves many tasks in the traditional process in the production process, and also saves the stacking space of various materials, saving the corresponding cost in labor, process and site. 7. The fireproof level of the meteorite fire door is high. Fire doors made with our door core panels are tested abroad and have a maximum fire endurance of 4 hours.
Ceramic Pressure Sensor have the characteristics of high quality, high stability, small size, low weight, compact structure, low cost and volume-production. It is widely used to measure pressure such as occasion of compressor, Auto, air-condition etc. The product is made of stainless steel and well-known brand sensor. The special transmitter converting circuit can adjust the zero value and the full range expediently. It also has the intrinsically safe certificate, the explosion-proof certificate and the CE certificate.
