Glass flake mastic and coating are compounded by epoxy vinyl resin and C-glass flake. They have excellent chemical resistance, high temperature wet corrosive gas resistance, extremely low water vapor permeability, small hardening shrinkage, low linear expansion coefficient, temperature shock resistance, small wear coefficient, simple construction, curing at room temperature and easy repair. Glass flake coating is simple in construction and can be applied by brush, roller and high-pressure airless spraying. Surface treatment shall be carried out before coating, and rust removal and roughening treatment shall be carried out by sand blasting and shot blasting after degreasing. Generally, 4 # sand or 20-40 mesh quartz sand is used, and 5-7kg/cm2 compressed air is used to drive the sand particles. The sand particles are sprayed from the nozzle at a speed of 50~70m/s, and the surface meets the SIS Sa2.5 specification. The dust after sand blasting is removed, and the coating is carried out within 8h. Coating is generally carried out in dry weather, with temperature above 5 ℃ and relative humidity below 85%. Use the same resin or glass flake (with smaller particle size) as the primer, with a thickness of 50 microns, and apply glass flake coating after the primer is dry. Pay attention to the following points when painting: a. Fully stir the paint; b. Mixing of coating base material and curing agent; c. Viscosity adjustment; d. Active shelf life; e. Cleaning and maintenance of painting equipment (machinery); f. Glass flake size.
Brick lining of oil storage tanks and storage tanks, storage of chemicals, anti-corrosion of brick lining of towers, pipelines and other equipment in various storage tanks, chemical reactions, mixing and separation processes. It is applicable to anti-corrosion of concrete surface structures such as floors, walls, ceilings, drainage ditches, large wastewater pools, sewage treatment equipment, concrete pools and storage tanks, and mariculture areas in chemical, pharmaceutical, and food plants. Cavitation of vinyl glass flake cement in desulfurization tower In desulfurization system, slurry delivered by circulating pump often contains a certain amount of gas. In fact, the slurry conveyed by the centrifugal circulating pump is gas-solid liquid multiphase flow, and the influence of solid phase on the pump performance is continuous and uniform, while the influence of gas phase on the pump is far more complex and difficult to predict than that of solid phase. When the liquid delivered by the pump contains gas, the flow, head and efficiency of the pump will decline. The larger the gas content is, the faster the efficiency will decline. With the increase of air content, the pump will have additional noise and vibration, which may cause damage to the pump shaft, bearing and seal. Primer painting After sand blasting, the surface shall be primed within 12 hours of a working shift or before visible surface rust spots are generated. If surface rust occurs, the area will be re blown according to the above requirements.
1 Enter the site and customize the scaffold according to the requirements of the construction site to meet the construction conditions. 2 Key points of construction, construction temperature between 15-20 degrees. The humidity shall not be greater than% 80. During construction, the bottom layer, the middle layer and the surface layer shall be constructed first. 3 Sand blasting for rust removal, painting sealing primer within 12 hours after rust removal, glass flake mastic construction after the primer is dry, glass flake mastic construction adopts the plastering method, with a thickness of about 1mm, generally completed in two times, and the latter process is carried out after the layer is dry. (General interval) During coating, hold the knife at a certain angle with the base course, push along the sharp corner of the knife in the direction of the sharp angle, squeeze out the air bubbles of the mortar and the foundation as far as possible, and do not stack and spread the coating along the same direction. 4. Local parts are strengthened with glass fiber cloth, such as lacing wire, internal and external corners, and the whole weld junction, so as to ensure the quality of the anti-corrosion coating at these parts. 5 It is difficult to apply solvent-free epoxy coating for finishing paint, and the use of active diluent and low viscosity curing agent increases the cost. Therefore, high solid epoxy coating is used (the volume solid content reaches more than 80%) It is also an optional environmental protection scheme.
The main feature of sewage and waste water tank is that its storage liquid contains acid-base, toxic and harmful substances, which will produce temperature changes during water treatment, so its anti-seepage requirements are relatively high. In the early days, sewage storage tanks had complex processes, mainly using reinforced concrete and impermeable agent processes, or some using FRP, anti-corrosion paint and other materials to build sewage tanks. In the early 1980s, the foreign chemical sewage industry adopted HDPE anti-seepage membrane as the cushion system of the pool. The main characteristics of sewage corrosion are: 1. water corrosion; 2. The types and corrosivity of corrosive media are complex and changeable; 3. The humidity in the air is high, the concentration of chlorine particles is high, and the concentration of harmful gases such as H2S and NH4 escaping from wastewater is high; 4. Corrosion of various microorganisms, bacteria and algae. In this atmosphere, the anti-corrosion requirements for concrete tanks and steel structures are harsh. The concrete tank shall not only be well treated for seepage prevention, but also be provided with reasonable anti-corrosion measures.
Features of vinyl glass flake cement: it has corrosion resistance, permeability resistance, and corrosion resistance to corrosive sewage, strong acid, strong alkali, salt, etc. The solid content can reach 1-1.5mm in one application. Temperature resistance and chemical resistance are superior to epoxy resin coatings. The construction is convenient, the quality is easy, the defective parts are easy to repair, and the coating protection life is more than 5 years. The coating is cured at room temperature, fast drying, good construction performance, excellent mechanical performance, electrical performance and adhesion. Vinyl glass flake mastic is suitable for flue gas desulfurization and smoke exhaust chimney devices in harsh environments in petrochemical plants, thermal power plants, iron and steel plants, non-ferrous metal metallurgical plants, pulp mills, paper mills, chemical plants, waste incineration plants and other departments. It is applicable to various vinyl glass flake mastics.
