1. Processing of aluminum alloy doors and windows The surface of the processed material must not have oil spots, aluminum chips, burrs or other stains; do not stretch excessively when any strip is embedded. It should be ensured that the strip is about 10 mm longer than the insert groove; the strip should be wrapped around one week, and the joint should be docked at the corner of the frame and should not be cut into several breaks. The joints, hardware and metal linings used in aluminum alloy doors and windows should be treated with surface anti-corrosion treatment except stainless steel. The glass block should be made of hard rubber or plastic, and no reclaimed rubber, wood chips or other absorbent materials should be used. The bead should be firm after assembly, and the gap between the butts should be no more than 1mm. The amount of overlap between the glass and the window shall be calculated from the edge of the window frame and the fan. The amount of overlap on each side shall be not less than 8 mm (the double glass shall not expose the aluminum spacer), and the glass shall be provided with a glass spacer under the assembly. 2, aluminum alloy doors and windows installation Before installation, the position of vertical, horizontal (elevation) and wall thickness must be determined. When the net port is installed, the reserved gap between the window frame and the opening of the hole is 5-8mm. When installing, ensure that the gap between the upper and lower sides is uniform. When the burr is installed, the thickness of the connecting piece shall not be less than 2mm. The diagonal deviation of the installation window frame is ≤2.0mm; the vertical deviation of the front and side frames (including the splicing materials) is ≤2.0mm; the horizontal deviation of the window frame (including the splicing materials) is ≤1.5mm; the elevation error is ≤5.0mm . Fixing method When installing the net port, use the expansion hose to directly fix the window frame to the wall; when fixing, the screw must be tightened with a screw. Do not directly knock it with a hammer. When the burrs are used, fix the window frame with the expansion hose through the connecting piece. On the wall. No matter what method is fixed, the fixing point shall not exceed 600mm, and the fixing member shall not be less than 50mm into the structural body. After the door and window frame is installed, there should be no arching, drooping, warping or deformation, so as to avoid obstructing the function of the switch; before installing the glass, the mortar and debris in the tank should be removed to make the drainage hole clear; after the window sash is installed, the appearance quality The surface is clean, no large areas of pitting, scratches, bumps, rust, etc.; the surface of the sealant applied is smooth, flat and free of air bubbles. The finished parts are completely installed and firm, and there should be no misplacement or less loading. The sealing strips should be even and firm after assembly. The joints at the corners of the frame should be tightly bonded and free from grooving. There should be no broken ends.
Biomass Generator is a fuel gas generating equipment ,it can generate fuel gas from biomass materials like wood scraps, straw, nut shell, branches, barks ect. All of biomass materials are all renewable through plant grow and collecting solar energy from sunshine. So the Biomass generator is a new energy equipment that utilizes the renewable energy from Biomass waste materials.
