Introduction of Dacheng Xiangdong Perlite Plate--Dacheng Xiangdong Insulation Refractory Material Factory 13473696600 15731614448 is made of inorganic bonding materials as the main raw material, which is modified by high-frequency rotation and fine processing. Strong adhesion, rapid cold curing speed (semi-curing and demolding displacement in one minute of cold pressing), high strength of finished product (1.0-2.5MPa/40-48mm thickness), low thermal conductivity (0.076W/mk) Moderate weight (300-400kg/m3), super water-resistant immersion (10% reduction in normal temperature water immersion for one year), acid and alkali resistance, freeze-thaw resistance, high temperature resistance (>1200°C), sound insulation and shock absorption Good, heat-insulating, flame-retardant, no smoky, high-temperature, high-temperature, non-toxic gas after burning (according to GB/T20285-2006 standard), stable performance, finished product fire resistance after reaching A1 level (40-43mm can reach 100 More than a minute, 45-48mm can reach more than 120 minutes), fully comply with the new standard of GB12955-2008 "Fire Door", the processing technology is simple, the turnover batch is small, the labor productivity is high, the occupied space is small, and the salary is saved by double. The cost is equivalent. It belongs to the environmental protection new type of fireproof roller blind filling, fire safety door and other special filling material binders. It is a new generation of aluminum silicate cotton, rock wool, glass water perlite board and foamed magnesite cement perlite board. . Safety application mechanism: This product belongs to the latest three generations of perlite board glue, replacing the first generation of glass water (high temperature hot pressing process - high cost) and the second generation of magnesite cement material (extracting process - complex and backward process) The perlite binder, because the first generation of the main body of sodium silicate and the second generation of binder magnesium chloride (brine) are all alkali metal salts, when the made perlite plate absorbs moisture, in the alkali metal salt Active cations such as sodium ions and magnesium ions will undergo displacement reaction with metal molecules, corrosive metals, and high-temperature open flame combustion will produce chlorine gas which is highly toxic. If used as a fire door core, the door core will rust and damage the door body, which will naturally be bad. The door starts from the heart, which shortens the life of the fire door and greatly damages the rights and interests of consumers. This is the fatal root cause of a large number of fire safety doors, including well-known brands, due to corrosion and negative user influence and daily increase. Even with coated steel plates, it will start to rot from keyholes, hinges, skeletons, solder joints, touches, scratches, etc., especially in wet areas such as the rainy season and coastal areas. The third generation of perlite slab glue developed by our company belongs to non-ionic binder. It is neutral and will not undergo displacement reaction with metal molecules, and each perlite particle is in the state of coating, and the film itself The high water resistance hinders the moisture absorption performance of the perlite, and does not cause corrosion to the metal contact points, thereby prolonging the life of the fire door. The newly developed third-generation perlite fire door core board has filled the domestic gap and changed the traditional “de-slurry†backward process to realize the assembly line operation of the door core products, which is favored by the majority of door enterprises. 3. Scope of application: Expanded perlite, expanded vermiculite, vitrified microbeads, etc., please consult before use! ! ! 13473696600
