Advantages of Changzhou glass fiber reinforced plastic corrosion protection project
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 characteristics of glass steel, is good corrosion resistance. Through the choice of the type and grade of the resin, the suitable molding process can be used to produce a variety of acid, alkali, salt and organic solvent glass fiber reinforced plastic products.
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. Therefore does not pollute the media, very easy to clean, the food and drug administration departments, special inspection, glass steel has reached the food brewing, pharmaceutical industry requirements.
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 process: not cured resin and reinforced materials have the ability to change shape, therefore, can be easily processed into the desired shape by different molding methods and tooling. This feature is the most suitable for large, complex equipment and construction requirements, applicable to the field of construction and assembly.
6, anti aging, flame retardant: glass fiber reinforced plastic is the category of products, matrix materials, natural aging and burning problem. 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, low comprehensive cost: glass fiber reinforced plastic as a new functional material, as a result of the high prices 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 metal equipment. 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. Layer thickness to adjust different media and loads.
What should be paid attention to in the construction process of Changzhou glass fiber reinforced plastic corrosion protection project
1, due to the construction of raw materials used for the flammable materials, all the construction workers into the site are not allowed to smoke, no fireworks.
2, construction environment temperature to 25 - 5 degrees Celsius is appropriate, 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, construction personnel to enter the site to comply with the rules and regulations, obey the foreman.
6, before the construction to ensure that the cement ground completely dry thoroughly, and then to carry out the work of the end of oil painting.
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 is a pool type, is not conducive to the formation of epoxy curing, it must be required 48 hours of curing time, to be fully cured after the use of.
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.
Working conditions of Changzhou glass fiber reinforced plastic corrosion protection project
1, the humidity is too large to add the desiccant, the temperature is too low, should be used to increase the temperature measure.
2, glass steel construction, should be strictly in accordance with the design requirements to check the quality of the work process, and to do a good job in the construction record.
3, the concrete base surface requires strong, dense, smooth, can not have a shell crack and other unqualified phenomenon.
4, raw materials in the form of pipe to the operation of the delivery, the construction site ready to have a fixed capacity of the batching equipment.
Treatment method for substrate before corrosion of glass fiber reinforced plastics in Changzhou
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 coating
