2, storage and storage of fire windows should be stored vertically in a dry room, and should have anti-corrosion measures, the glass should be placed and rely on objects that can not damage the glass edge and glass surface.
3, installation
(1) The fire window must be inspected before installation. If the window frame, window sash is warped, deformed or damaged due to inadvertent transportation and storage, it should be repaired before installation.
(2) When the fire window is installed, it should be leveled with a horizontal ruler or the vertical line of the front, back, left and right by the hanging line method, so as to be horizontal, vertical and high.
(3) The window frame must be integrated with the building and connected to the wall by wood or iron. After the steel window frame is installed, the cement mortar must be poured between the rear window frame and the wall, and it can be used normally for 24 hours.
(4) The position of the mounting holes of the hardware fittings should be accurate, so that the hardware fittings can be installed flat and firm, and meet the requirements for use.

(6) In addition to the above requirements, the installation shall be carried out in accordance with the requirements of the “Construction and Acceptance Specificationsâ€.
Semi-friable aluminum oxide is a kind of high-grade corundum synthesized by some advantages of brown corundum and white corundum. Its friability is between white corundum and brown corundum. Its grinding performance is unique, and its application range is wide. Semi-friable aluminum oxide has good toughness and self-sharpening. It can be used in the manufacture of ceramic grinding tools, resin grinding tools and coated abrasives. The bonded abrasive tools with semi-friable aluminum oxide have high durability, good self sharpening and retention. Under the same conditions, the surface quality, the processing efficiency and the durability of the grinding tools which produced from semi-friable corundum are better than those of brown, white, chromium and single crystal corundum when processing some workpieces. For rough grinding, the machining efficiency can be improved, and the surface quality of the workpiece can be improved by fine grinding.
