The height difference between the benzene plates must be polished. When pasting the EPS benzene board, it should be operated by pushing and squeezing in the range of 20 cm above and below. When the size of the metal engraved plate is too large, the construction problem may be caused by the unevenness of the base layer and the plate, resulting in a false bond and difficulty in adjusting the surface flatness.

The consistency of the configuration of the glue is too low or the viscosity index of the bonding glue is not accurately controlled, so that the initial viscosity of the glue is too low, and the sag generated when the glue is attached to the wall causes the board to be empty and empty. . When the construction of the thermal insulation layer is not carried out, the outer surface of the metal engraved board surface is not evenly squeezed by the hands, but the end of the board is forcefully pressed to cause the other end to be lifted, causing the other side of the board to be hollow and vacant.

Knocking, patbing, and vibrating the surface of the board during the construction of the metal-engraved board can cause the adhesive glue to produce empty drums and virtual stickers. There are also hollow cracks in the protective layer, the top layer and the plaster layer, which are often caused by the loss of control of the construction operation. In the construction, there is no accurate operation according to the requirements of the technical regulations. The unevenness and uneven distribution of the glue applied to the metal carved plate of each piece will lead to virtual stickers and empty drums.

The materials of the external wall insulation board are also constantly emerging with new products. The emergence of new products such as metal-carved insulation boards has also increased the number of products for the industry. There are two main types of equipment for producing exterior wall insulation materials: Ordinary dry powder mixer, the other is a special equipment for external wall insulation mortar. These two devices have their own advantages and disadvantages, as detailed below.

As the external wall insulation materials, it is known that the external wall insulation materials have very strict requirements on the mixing process. If the materials are mixed unevenly or the damage rate is high, the insulation properties of the materials will be affected. Ordinary dry powder mixer can also be used as a mixing device for exterior wall insulation materials, but only can be mixed with general external wall insulation materials. The insulation performance of the external wall insulation products produced is general, and the requirements for thermal insulation performance are not high. Building community.
