The structure of composite rock wool board is mainly divided into four layers: adhesive layer, thermal insulation layer, smear layer, coating layer and related auxiliary materials. The adhesive layer is between the bottom layer and the surface layer, and the upper layer and the lower layer are firmly combined with the cementitious material. There are four problems that should be paid attention to when making composite rock wool board. The following is the analysis of Jinan rock wool board manufacturer.
<1> According to the production process parameters, the technical requirements for composite rock wool board before delivery are specified. After the composite rock wool board is installed, the appearance of the composite rock wool board shall reach the same color card number, and the composite rock wool board shall be free of color difference defects. There should be no obvious impact or scratch on the exterior of the composite rock wool board, whether there is a lack of supporting accessories, and whether the panel, ceiling, mat, bottom slot and other accessories will arrive.
<2> : The composite rock wool board shall enter the factory before quality inspection and have products. The certificate of unqualified products is not allowed to be installed on board. Construction tools should be prepared for construction: tape measure, stone pen, boxing, profile cutting machine, welding tools, hammer, etc.
<3> : Welders are on duty. Qualified welders shall be qualified to Level III before assessment and action. When electric welders are on duty, they must wear a special type of work license. Process requirements. The predetermined production parameters are required for manufacturing composite rock wool board according to the prior art. The composite rock wool board installed on the same color card shall be free of color defects after appearance.
<4> : If the damage area is large or the scratch length is greater than the necessary change, there should be no obvious impact or scratch outside the composite rock wool board. The installation process specification for the partition composite rock wool board above the door frame is as follows: the lower plate is a panel with the same width as the door frame, with traces. There must be no stitch. After the composite rock wool board is installed, the perpendicularity of the whole board is the flatness of the board joint, and the top flatness of the composite rock wool board is the flatness of the board joint. The gap between the ceiling and the top profile is not greater than. The ceiling seam shall be in the same straight line.
