The specifications, sizes and shapes of the heating cover conform to the design requirements. The surface angle of the individual heating cover is circular arc, the leakage net is consistent with the frame of the heat shield, and the installation and dismantling is free. The heat cover should be natural and regular. The top part of the heating hood is firm in structure, wooden keel and decorative panel. F white is in accordance with the standard of woodworking material, and the quality of wood surface coating is in line with the requirements of blockboard production.
The construction of heating hood should start after the indoor ceiling and wall have been completed, and the base wall should be leveled. The wooden dragon and its finishing materials made by heating cover should conform to the standard of fine wood decoration. The material is free from defects, moisture content is less than 10%, and the moisture content of plywood is less than 8%. The keel should be red and self pine. The skeleton of the heating hood must be opened and linked. The Mead eye and the glue should stick to the bar, and the connection must be firm. The panels should be processed with the right size, smooth surface, smooth lines, tight fitting, no stick, glue, nail cap and pollution. Heating cover wood production is completed, should be immediately finishes, brushing again oil before other operations.
The common quality problems in the construction of heating hood are mainly reflected in two aspects. In terms of structure design, the main quality problems are small heat dissipation surface and no hot gas circulation circuit, resulting in insufficient heat emission and easy deformation of decorative materials. When the heating hood is equipped with juice, there should be enough heat dissipation space, and the vent should be designed at the bottom of the heating hood, so that the air will form a loop in the hood and accelerate the heat dissipation of the radiator. Common quality problems in construction and fabrication are specification deviations over production standards. The standard of heating cover is: the height deviation of the heating cover is less than 1 millimeters, the surface evenness deviation is less than 1 millimeter, the perpendicularity deviation is less than 2 millimeter, and the flatness deviation of the upper mouth is less than 2 millimeter. Can be adjusted by adjusting the plane, Tianjiao skeleton. The quality problems and treatment methods of the heating hood decoration are found in the quality inspection part of the paint works.
The production and installation of the heating cover is a highly technical project. The construction period begins with the completion of the top and wall base treatment, and finish the final paint painting before the completion of the project. Such as 7 rooms and two rooms with a total of 7 heating covers, carpenter production needs 5 days, the painter based on the use of varnish varieties and different construction methods, in general between 3~8 days, with other wood decorating oil at the same time, the rest for the waiting time.
