Advantages of Huzhou FRP anticorrosion engineering
1, lightweight glass steel: the proportion of only 1.4-2.0, while the tensile strength of steel fiber wrapped glass up to 300-500Mpa, exceeding the ultimate strength of ordinary steel, such as the calculation of strength, also has reached or exceeded some special alloy steel, it can be used as the main structure material anti-corrosion equipment, and transportation, convenient installation and maintenance the advantages of.
2, excellent corrosion resistance: one of the biggest features of glass fiber reinforced plastic, corrosion resistance is good. Through the selection of the type and the grade of the resin, the glass fiber reinforced plastic products can be produced with various kinds of acid, alkali, salt and organic solvent.
3, good surface performance and easy cleaning and sterilization properties: because the glass steel is integrally molded, seamless, smooth inner wall, and chemical medium, there is little corrosion and scaling phenomenon of the surface, but do not breed bacteria and microorganisms. So do not pollute the medium, easy to clean, by the food and drug administration department for special inspection, glass fiber reinforced plastic has reached the requirements of food brewing, pharmaceutical industry.
4, good design: glass steel can change its raw materials, in proportion to the number and arrangement of a reinforced material, composite materials to meet different performance requirements.
5, good construction technology: uncured resin and reinforced materials have the ability to change shape, therefore, can be easily formed by different molding methods and molds to the desired shape. This feature is most suitable for large, complex and complex equipment and construction requirements, suitable for field construction and assembly.
6, aging resistance, flame retardant: glass reinforced plastic products are reinforced, the substrate material has a natural aging and combustion problems. But the world after 60 years, China after more than 30 years of research, it has been solved, reinforced materials and coupling agent treatment, the use of 50 years, the bending strength of insurable lasting in 64-46%, tensile strength retention rate at 71.2%, such as adding antioxidant, anti-aging performance is better; the glass substrate and adding flame retardant the flame retardant resin adding flame retardant, the oxygen index reached 34-36, fully meet the requirements of fire retardant fermentation equipment.
7, the overall cost is low: glass fiber reinforced plastic as a new functional material, because of the higher price of raw materials used. Generally speaking, the price of FRP equipment is higher than that of carbon steel equipment and some plastic equipment, but lower than that of stainless steel and other non-ferrous metals. But because the glass steel light weight, good corrosion resistance, long service life, less maintenance advantages, its installation and use cost and low comprehensive cost; and for some complicated working conditions or severe equipment, can be used to each in his element for heating coil, such as stainless steel or titanium, lined with plastic material. In order to achieve not only has excellent performance and can reduce the cost objective. The thickness of the layer is used to adjust the different media and loads.
What should be paid attention to in the construction process of Huzhou FRP anticorrosion engineering
1, due to the use of raw materials for the construction of flammable materials, all personnel entering the site shall not smoke, no fireworks.
2, the construction environment temperature to 5 - 25 degrees, relative humidity is not more than 8%.
3, glass steel anti-corrosion engineering construction strict inspection before the ground foundation is smooth, on the ground is not completely dry impervious conditions due to the construction of the construction in the basement so that the ring when necessary with ventilation and low-voltage lighting facilities.
4, the corrosion resistance layer of smooth surface, the enhancement layer convex part of the wall thickness of the height shall not exceed 20%.
5, the construction personnel to enter the scene to comply with the rules and regulations, obey the foreman arrangement.
6, before construction to ensure that the cement surface is completely dry foundation leveling, and then to the bottom oil painting work.
In 7, when brushing enamel on site must send fresh air to keep the tank with fresh air ventilator, construction or wearing a mask in order to better.
8, due to the construction environment belongs to the pool irrigation class, is not conducive to the formation of epoxy curing, so it must be 48 hours of curing time, after curing can be used.
In addition to the matters needing attention in the construction process described above, glass steel anti-corrosion engineering, also must strictly enforce the technical specification for safety, smooth operation, no illegal command and operation, accidents, personal lines and equipment.
Operating conditions of Huzhou FRP anticorrosion engineering
1, when the humidity is too large to add dehumidifier, the temperature is too low, should be used heating measures.
2, glass fiber reinforced plastic construction, should be strictly in accordance with the design requirements to check the quality of the process, and do a good job of construction records.
3, the surface of the concrete base requires strong, dense, smooth, can not have cracks, such as shell cracks.
4, raw materials used in the pipeline to the operation of the Department of transportation, the construction site to prepare a fixed capacity of the batching equipment.
Treatment method of glass fiber reinforced plastic in Huzhou
1, acid (base oil used in more): using metal rust remover for cleaning oil steel structure surface, and then rinse with water, and with the scrub brush, which can remove more oil.
Methods: 2, mechanical grinding machine with clear surface oxide skin, rust steel structure membrane residual sand, welding slag, dust, oil and other substances, to make the coating firmly attached on the surface of the workpiece, it must be cleaned prior to coating on the surface of the workpiece, otherwise, not only affects the binding force of the coating with the base metal and corrosion resistance, but also to the
