Shandong Cheng Ming and you analyze the use of glass-lined equipment Putty and damaged glass-lined equipment is widely used in chemical production. Its attached to the surface of the tire iron vitreous enamel layer is smooth and clean, extremely abrasion resistant glass-lined reactor 500l, for a variety of inorganic and organic corrosion resistance of stainless steel and plastic materials can not be compared; it has both general metal the mechanical strength of the device, there they do not have the characteristics: material deterioration prevent discoloration, eliminating the metal ion contamination, and inexpensive, convenient and practical. Therefore, glass-lined equipment is the preferred equipment pharmaceuticals, dyes, food processing and other fine chemical industries. Because, after all, is a brittle glass-lined lining material, harsh working conditions (abrasion and corrosion) do not allow any minor cracks its existence, and therefore require special care during the operation of the transportation, installation and use of its equipment and the like, but also pay attention to maintenance, to ensure the safe use of equipment performance. Even so glass-lined reactor, due to various reasons following, glass-lined equipment damage still exists: 1. Transportation and improper installation; 2. Entrained within the material metals, stones and other hard objects hit the wall; 3. Thermal shock temperature difference is too large, exceeding requirements; 4. Acid and alkali materials at high temperature and high concentrations of corrosion; 5. Overload in the abrasive, corrosive conditions. Additionally, there are clear foreign bodies improper methods and poor quality vitreous enamel layer factor. Through the use of glass-lined equipment business visits to the investigation informed: for small accessories such as mixing, valves, fittings and other damage is found soon abandoned its removable still; for large equipment such as reactor type, tower section, storage tanks and other damage is found f type glass-lined reactor, had to be disassembled and shipped to their manufacturer, reconstruction of vitreous enamel layer. Both methods exist both serious waste, but also affect the production. Especially in today's equipment substantial price increases (eg k1000l reactors now for the price of four times in 1988). So with the increasingly widespread use of glass-lined equipment, looking for a simple and efficient enamelled lining repair technology has become necessary, ceramic metal enamelled Putty (Putty enamel reactor) came into being. Knowledge about the enamel reaction tank Xiao Bian here today to find out more about the hope that interested friends can look carefully. Enamel reaction tank after calcination is about 900 ℃, and after cooling technology enables the use of special steel enamel and bonded together. Since the linear expansion coefficient of the enamel and elongation of less than steel, and therefore the amount of deformation after cooling is less than the amount of deformation of the glass-lined steel, such enamel steel sheet will be bound by compressive stresses. When the reaction tank made of enamel, the enamel layer that is the presence of its pre-compression stress, while the presence of the steel sheet is prestrained stress. Since the linear expansion coefficient related to the prestress and elongation, coefficient of linear expansion and elongation and temperature are closely related, and therefore greatly affect the use of enamel reaction tank to its operating temperature. If the temperature changes due to stress caused by leaving the enamel over the use of stress, the enamel will be destroyed. Role enamel reaction tank is mainly for containing corrosive chemicals, such as various acid. Therefore, the reaction tank enamel enamel layer cold, hot CML, easily chipping. Therefore, there is enamel reaction tank temperature limit, the maximum temperature not higher than the temperature of 200 ℃, acute cold shock temperature less than 110 ℃, thermal shock is less than 120 ℃. Temperature and storage tank temperature too much material and vapors when heated too much, too fast cooling can also lead to chipping. So do not cause greater containing liquid temperature, otherwise detrimental to the tank. Enamel reaction tank is very poor impact resistance, any metal, hard object hit them will result in damage to the enamel. Therefore, the process of using enamel reaction tank to prevent any metal, hard object fall into the kettle, in case of blocking material, must use clear plastic rod, cover the lid overhaul to prevent melting slag pits or porcelain surface appear chipping.
