There is an FRP jar. The inner surface layer of the equipment (thickness is about 4mm) is made of MFE-2 vinyl resin. Now I want to use it to store a catalyst. This catalyst mainly contains Co, Mn, Br ions and acetate ions. Can you bear it? I found some information online and it was said that MFE-2 vinyl resin is an excellent corrosion-resistant resin with a high heat distortion temperature and can be used for a long time at 120°C. This product is mainly suitable for making various corrosion-resistant integral fiberglass products and linings with high temperature resistance, as well as making linings for metal and concrete structures. ; Corrosion-resistant resin mortar floor, granite and acid-resistant silicon board jointing. Chemical resistance test results: Medium concentration at normal temperature 80℃ Medium concentration at normal temperature 80℃ Sulfuric acid 75% Hydrofluoric acid resistance 20% Sulfuric acid resistance 50% Hydrofluoric acid resistance 40% Sulfuric acid resistance 25% Glacial acetic acid resistance It is certain that this resin is acid and alkali resistant, but I don’t know if it is resistant to halogen ions? In addition, vinyl resins include several types: Vinyl Ester Resins are internationally recognized as highly corrosion-resistant resins. 1. Standard bisphenol A epoxy vinyl resin is a vinyl resin synthesized by the reaction of methacrylic acid and bisphenol A epoxy resin. It has been dissolved in styrene solution. This type of resin has the following characteristics: 1. The double bonds at both ends of the molecular chain are extremely active, allowing the vinyl resin to solidify quickly, gain strength quickly, and obtain a highly corrosion-resistant polymer. ; 2. It is synthesized using methacrylic acid. The methyl group on the side of the ester bond can play a protective role and improve hydrolysis resistance. ; 3. The resin contains less ester bonds, 35-50% less per mole than chemical-resistant polyester (bisphenol A-fumaric acid UPR), which improves its alkali resistance. ; 4. More secondary hydroxyl groups can improve the wettability and adhesion to glass fiber and improve the mechanical strength of laminated products. ; 5. Since it is only cross-linked at both ends of the molecule, the molecular chain can elongate under stress to absorb external force or thermal shock, showing resistance to micro cracking or cracking. 2. Flame-retardant vinyl resin is generally synthesized from brominated epoxy resin. Since the resin contains bromine, flame-retardant vinyl resin can be flame-retardant while having chemical resistance. 3. Novolac epoxy vinyl ester resin: Novolac epoxy resin is introduced into the skeleton of vinyl ester resin. The synthesized vinyl ester resin is generally called Novolac vinyl ester resin. The resin has high thermal stability. After the resin is cured, the cross-linking density is high. Its heat distortion temperature reaches 120-135°C, which can extend its service life and has excellent corrosion resistance, especially for chlorine-containing solutions or organic solvents. In order to meet the needs of high-temperature strength, many manufacturers have modified phenolic epoxy vinyl ester resin to improve the cross-linking density and heat resistance of the resin. It has excellent acid resistance, solvent corrosion resistance and oxidation resistance, and is suitable for various high-temperature and strong corrosion situations, such as desulfurization devices (FGD), high-temperature chimneys, etc. 4. Flexible vinyl ester resin In order to meet the needs of various anti-corrosion engineering construction, flexible vinyl ester resin has been developed. Flexible vinyl ester resin has high adhesion to steel and concrete surfaces. Compared with traditional epoxy vinyl ester resin, its elongation is higher and the bonding strength is higher. * * The impact strength is increased by nearly 4 times, the interlayer strength is increased by 20%, and it has unique wear resistance. ①Used for corrosion-resistant linings, grouting materials or primer resins, such as the primer in the production of integral mortar floors, which can omit the production of fiberglass isolation layers in domestic construction operations, improving overall performance while also saving costs. ; ②Bonding of various materials such as pipe fittings ; ③Used with Kevlar fiber or other reinforcing materials to make high-strength and fatigue-resistant products, such as sports or military helmets, sailboats, etc. 5. PU modified epoxy vinyl ester resin This type of resin is made by modifying epoxy vinyl ester resin with urethane (such as TDI), and has both intra-chain unsaturation and chain-end unsaturation. Compared with ordinary bisphenol A epoxy vinyl ester resin, it has excellent corrosion resistance, flexibility and good processability. Due to the introduction of urethane, the compatibility between the resin and the fiber is improved, and the resin surface can maintain good air-drying properties. Suitable for various processes such as winding. In addition to the above varieties, there are two major categories of vinyl ester resin in the domestic market:: One type is acrylic vinyl ester resin used by many manufacturers, or modified with urethane based on this resin. The temperature resistance level of this type of resin is 10-20°C lower than that of the corresponding methacrylic vinyl ester. The elongation of the resin increases, but due to the lack of protection of the ester bond by the methyl group, the corrosion resistance of the resin, such as alkali resistance, decreases. ; Another type of resin is a specialty product in my country. It is fumaric acid modified bisphenol A epoxy vinyl ester resin, but strictly speaking, it is not a vinyl ester resin, but a transitional variety between vinyl ester resin and bisphenol A unsaturated polyester resin. This type of vinyl ester resin has the characteristics of high cross-linking density, brittleness and large shrinkage. Since the ester bond content in the resin is 40-50% higher than that of standard vinyl resin, its alkali resistance is relatively poor. Which type of MFE-2 type resin does it belong to? Can Haiyou help confirm whether the above catalyst can be stored?
Should be able to bear it; However, the operating temperature depends on the resin used in the structural layer of the tank. Because only the inner surface layer of the equipment is vinyl resin, the operating temperature of the tank cannot be determined based on the operating temperature of the resin on the inner surface layer.
Thank you everyone above. I'll check some more information.
