However, at the same time, pay attention to the following matters: It must be used together with fixtures such as light steel keels or wooden strips, especially in combination with rigid and non-deformable fixtures to maintain aesthetics and distortion. When locking the calcium silicate board, it is necessary not only to pay due attention to the flatness of the board due to the allowable tolerance thickness of the board, but also pay attention to the installation; and to maintain a better aesthetic effect, the hole can be reamed 2~3mm in the board surface. Depth so that the tail of the screw is not exposed to the surface of the board. To reduce or avoid dust during sheet metal cutting, the surface of the sheet can be wetted along the processing line or processed in a ventilated place. Pay attention to the seam between the board and the board to avoid affecting the appearance. 3 Introduction and classification of the production process of calcium silicate board is based on the “Golden Palace†brand ordinary calcium silicate board of Sanming New Building Materials General Factory: the main raw materials such as asbestos fiber, slaked lime and quartz powder are made into uniform concentration according to the proportion of ingredients. The slurry and the slurry flow are placed on the running closed felt to form a slab by vacuum dewatering and high pressure molding, and the slab is pre-cultured, high temperature and high pressure curing, and a chemical reaction is formed to form a semi-finished calcium silicate board with tobe mullite as a main component. . The semi-finished products are dried by a comb dryer, sanded on the surface of the sander and guided by the angle guide, and the "Golden Palace" brand ordinary silicic acid consumption board is formed. This is the main production process. According to the industry standard, the calcium silicate board is classified into D0. 8, D1.0, and 01.3 by density. For example, the D1.0 type calcium silicate has an extremely high density of between 0*9 and 1 20 g/cm3. Sanming New Building Materials General Factory is divided into: ordinary calcium silicate board, non-asbestos calcium silicate board, sand-free calcium silicate board, molded calcium silicate board, etc. according to different raw materials and production methods. In summary, it is our shallow understanding, and we hope that you will be advised. The expected goal of the “10th Five-Year†development of the building materials packaging industry has once again revised the national standard of “cement packaging bagsâ€, and strived to formulate three types of packaging forms for cement packaging at an early date. The bulk assembly rate is not less than 30%, and the bagging rate is reduced to 70%. the following. Cement circulation, reduce circulation, develop door-to-door transportation, no leakage of bulk cement, no damage to container cement, comprehensive damage rate of bagged cement is not more than 1%. The main substrate used for container and bag is: stretch paper bag paper , laminating woven fabric, reinforced paper, burying paper, etc. Improve the quality of the substrate and reduce the packaging. All the cement paper bags are abandoned and changed into a paste, and the machine bag pocket is used to develop a series of bags of 50kg or less. Optimize the industrial structure of cement packaging machinery, develop packaging machinery products with new technical content, meet domestic requirements, and go abroad. The production management level of cement packaging has reached a new level, from the fixed point management to the international quality certification. Strive to amend the national standard of "flat glass container equipment", and strive to develop and implement the "flat glass packaging" national standard. Flat glass packaging has a level of assembly of more than 60%. Develop new substrate base materials for assembly equipment, improve the product structure of container equipment, eliminate backward products, and develop innovative assembly equipment. Development of the use of deep-processed glass assembly equipment. Optimize the structure of wooden boxes, advance the application of nail guns, shaped nails and advanced box making processes and techniques, develop and use high quality filler materials or filling forms. The damage rate of glass packaging is not more than 0.3%. The glass breakage rate caused by poor packaging during circulation is not more than 2%. Strive for “door-to-door†container transportation accounted for 50% of the total glass transportation volume, and develop large-scale float glass transportation. The car and connection measures are used by people.
