At Present, The Appropriate Structural Fixation Method Adopted By Fire Door Manufacturers Is Cement Mortar

The fireproof door manufacturer has the characteristics of good thermal stability, fire prevention, moisture-proof, acid-base corrosion resistance, firmness, durability and easy cleaning. The commonly used shaft brick is a thin fine ceramic product. It is glazed on the surface of porous green body and fired at a certain temperature. The surface of shaft brick is a smooth contact layer, and the back is a ceramic green body with concave convex grain, which has a large water absorption. Cement mortar is mostly used for paving during construction. The groove on the back can enhance the binding force between the face brick and mortar. The shaft brick is divided according to the color of the shaft surface, including monochrome color and pattern brick: according to the nature, there are square, rectangular and special-shaped accessory brick. Ceramic mosaic decorative ceramic mosaic is a decorative material made of small flake ceramic tiles made of porcelain clay, which are assembled into various patterns and pasted on paper, including hanging shaft and non hanging shaft.

It is hard, durable, colorful, acid and alkali resistant, fire-resistant, wear-resistant, impermeable, strong pressure resistance and low water absorption. With the development of modern architecture, ceramic mosaic is widely used for floor and internal and external wall finishes. The ceramic mosaic finish method is: generally, cement mortar is used as the bottom ash, the thickness is, and then the thickness is, The mix proportion is paper reinforcement: lime paste: cement:: cement paste, or paste glass mosaic with glue mixed with cement or polyvinyl acetate emulsion. Glass mosaic is a small piece of decorative material pasted on paper made of glass. The fire door manufacturer has a variety of colors such as transparent milky white, gray and blue. It is characterized by hard texture, stable performance, heat resistance, cold resistance, atmospheric resistance, acid and alkali resistance, no cracking, and smooth surface. Because of the poor water absorption, in order to strengthen the bonding force with the mortar, the geometric shape is made into a plane on the front and slightly concave on the back, and the groove section is trapezoidal. This not only improves the bonding surface behind a single block, but also increases the bonding between blocks. The bonding process of glass mosaic is different from that of face bricks. It usually depends on the made paperboard to map plate by plate.

Due to the bonding condition of glass matu glass mosaic and small pieces of SAIC, the vertical and horizontal lines of sub plate shall be snapped in the door and window holes at the corner of the wall; The glass mosaic of the paperboard is full of thick white cement glue slurry. Spray water on the wall with the line. After pasting the paper plate, pat it gently with a mud board until the glue slurry is filled with the block joint. After the initial setting, spray water to wet the paper surface, uncover the paper, straighten the inclined block, and set it, The artificial marble veneer on the surface of scrubbing glass mosaic is a wall decoration material produced by prefabricating the texture of imitation marble. It can be roughly divided into four types: polyester artificial marble, sintered artificial marble, inorganic cemented artificial marble and composite artificial marble, The physical and mechanical properties, water related properties, adhesion properties and other aspects are different, and their fixation methods are also different. At present, the appropriate structural fixation methods adopted by fire door manufacturers include cement mortar pasting, polyester mortar pasting, adhesive pasting and hanging method. Polyester artificial marble can be pasted with cement mortar or polyester mortar. The ideal adhesive is adhesive, but the cost is too high. In order to reduce the cost, unsaturated polyester resin with the same composition as artificial marble can be used as adhesive. A certain amount of medium sand can be mixed in the resin, and an appropriate amount of initiator and agent can be mixed. Good results can be achieved by pasting with such bonding mortar. The paste structure of sintered artificial marble is similar to that of axial brick.
