Stainless steel water tank is mainly made of stainless steel material, with excellent corrosion resistance and strong load-bearing capacity. The FRP water tank is composed of glass fiber and organic polymer materials, with light weight, corrosion resistance, anti-aging and other characteristics. Second, in terms of performance, stainless steel water tanks have excellent load-bearing capacity and stability, and can withstand greater pressure and impact. 1.Specifications: Commonly used stainless steel plates are divided into two models: 201 and 304. The actual composition is different. 304 is of better quality but more expensive, and 201 is worse. 304 is imported stainless steel plate, and 201 is domestic stainless steel plate. 2.The composition of 201 is 17Cr-4.5Ni-6Mn-N, which is a Ni-saving steel type and a substitute steel for 301 steel. It becomes magnetic after being cold worked and is used for Railway rolling stock. 3.The composition of 304 is 18Cr-9Ni, which is the most widely used stainless steel and heat-resistant steel. Used in food production equipment, Xitong chemical equipment, nuclear energy, etc. 4.201 has a high manganese content, and the surface is very bright with dark brightness. The high manganese content makes it easy to rust. 304 contains more chromium, has a matte surface, and does not rust. Put the two together to compare. The most important thing is the difference in corrosion resistance. The corrosion resistance of 201 is very poor, so the price is much cheaper. And because 201 contains low nickel, the price is lower than 304, so the corrosion resistance is not as good as 304. 5.The difference between 201 and 304 is the nickel content. Moreover, the price of 304 is relatively expensive now, but 304 can at least guarantee that it will not rust during use. (Stainless steel potions can be used for experiments) 6.Stainless steel is not easy to rust because it forms chromium-rich oxides on the surface of the steel body to protect the steel body. 201 material is a high-manganese stainless steel that is harder than 304, with high carbon and low nickel. 7.Different compositions (mainly distinguish 201 and 304 stainless steel in terms of carbon, manganese, nickel, and chromium) steel number carbon (C) silicon (Si) manganese (Mn) phosphorus (P) sulfur (S) chromium ( Cr) Nickel (Ni) Molybdenum (Mo) Copper (Cu) AISI(304)≤0.08≤1.00≤2.00≤0.045≤0.0318-208-10 AISI(201)≤0.15≤1.005.5-7.5≤0.05≤0.0316-183.5-5.5 What is the difference between 3161 and 304? 1.Different chemical compositions. 2. 304 is cover-type stainless steel, and its material composition is OCr18Ni9. 3. 316L is Ominti stainless steel, and its material composition is 00Cr2Mo2Tl. 4. Different properties, 304 steel can resist corrosion such as phosphoric acid, sulfuric acid, formic acid, urea, etc. 5. 304 steel type is suitable for use in situations where general water, control gas, wine, milk, CIP cleaning fluid, etc. are less corrosive or do not come into contact with materials. 6. 316L steel type adds molybdenum element on the basis of 304, which can significantly improve its resistance to intergranular corrosion. 316L stainless steel is suitable for: seawater equipment, chemical, dye, papermaking, oxalic acid, fertilizer and other …Read More

FRP: Fiber-reinforced plastic is a composite material. Generally, glass fiber is used to reinforce unsaturated resin. The matrix of epoxy resin and phenolic resin is reinforced plastic with glass fiber products as reinforcing materials. It is called glass fiber reinforced plastic or called glass fiber reinforced plastic. It is fiberglass, which is different from tempered glass. FRP is generally divided into manual pasting, SMC molding, pultrusion, and winding processes... It is an anti-corrosion material and has good anti-corrosion resistance to acid, alkali and sewage. Different FRP materials are used for high-strength acid, alkali and high-temperature water, such as There are many models of epoxy resin and 3301 resin, just match the model. 1.Manual pasting is an old process: the main ingredients are fiber cloth, resin, talcum powder, catalyst and curing agent. One layer of cloth and one layer of oil are hand-made, and the thickness of the paste is determined according to the requirements. Widely used in daily life, factories, pipelines, irregular small products, tanks and tanks, cement pools, etc. 2.SMC molding is a product that is pressed and formed by a four-column press using a high-temperature mold. Materials such as fiber yarn, zinc stearate, calcium powder, resin, reinforcing agent, and curing agent are mixed into a paste, and the sheet is formed by a sheet machine. shape, cured in a greenhouse and then molded by a four-column press. The thickness of the water tank plate depends on the pressure-bearing height of the water tank. The pressure-bearing refers to the water's own pressure. Molded products, water tank panels, meter boxes, telephone pole fences, septic tanks, simple toilet houses, food factory pallets, handicrafts, etc. 3.Pultrusion products: It is an injection molding method. It also uses resin, fiber yarn, calcium powder, zinc stearate and other materials or pastes through the mold to inject them into the mold or spray them on the product with an injection molding machine. Molded products such as shell boxes and grilles , Profile angle steel type, channel steel type, square steel type and other products. 4.Winding process: Winding is usually used on the tank. First, the two ends of the tank are sealed by hand. According to the diameter of the tank, a flat plate is then pasted into a cylindrical shape. It is placed on the equipment and adjusted to the center. The fiber is used by rotation. The yarn is wrapped around the cylindrical tank through paste resin, which is a cross-wound tube. The finished products are commonly used in septic tanks, acid and alkali resistant tanks, sewage tanks and other products. Product overview: SMC water tank panels and SMC combined water tanks are new water tanks commonly used in the world. They have the advantages of no leakage, light weight, good water quality, beautiful appearance, long service life and easy installation. Its unique performance completely solves the problems of heavy weight and easy penetration of concrete water tanks. This water tank is a key scientific and technological research project of the "Seventh Five-Year Plan" …Read More
