Anticorrosive special resin 3301

3301 corrosion-resistant resin 3301 belong to bisphenol A type high corrosion unsaturated polyester resins. Because of its molecular structure, the introduction of bisphenol A structural units, so that the chemical stability and mechanical properties of the resin are higher than orthophthalic and isophthalic polyester resin. 3301 resin had a number of major preservation projects in the country, the effect is quite good, being in the field of preservation experts alike. China Metallurgical Construction Research Institute was included in the anti-corrosion engineering. The resin is a resin suitable for manufacture of various high-grade glass fiber reinforced plastic (FRP) tank cylinder corrosion, heat pipes, and equipment (such as corrosion-resistant fans, etc.); anticorrosion chemical, electroplating, electrolysis and other industries flooring; various FRP high-strength structural parts, and ring epoxy resin with advanced motor pullout wedge. Technical indicators Project 3301 Appearance yellow viscous liquid acid value (mgKOH / g) 12.0 ~ 20.0 Viscosity (Pa.S / 25 ℃) 0.32 ~ 0.52 gel time (min / 25 ℃) 8.0 ~ 14.9 Solid content (%) 53.0 - physical and mechanical properties of 3301 projects 59.5 flexural strength (MPa) Casting 115 Impact Strength (KJ / m2) Casting 6.9 Elongation at break (%) Casting 3.0 heat distortion temperature (℃) Casting 113 Barcol Hardness Casting 44 Note: 1) sample preparation method execution 2) sample processing method according to GB / T8237-2005: after 24 hours at room temperature curing + 40 ℃ 2 小时 + 60 ℃ 2 小时 + 80 ℃ 3 3h + room temperature for 24 hours. Chemical properties (FRP) Name Concentration temperature resistant assess Name Concentration temperature assessment sulfuric acid nitric acid 5% 90 ℃ 50% 80 ℃ still resistance to sulfuric acid at room temperature resistance of 70% sodium hydroxide 10% 50 ℃ still resistant to 36% hydrochloric acid at room temperature resistant sodium hypochlorite 50 % 20 ℃ still resistant to hydrochloric acid 10% 90 ℃ benzene resistant --- 5% nitric acid at room temperature is still resistance to corrosion in distilled water at room temperature --- 90 ℃ resistance Note: The table is standard FRP producers assessment sample test results in certain etching solution, for reference, before the selection should be done coupon corrosion test. Ⅱ recipe name curable resin 100 hardener systems 2-6 1-3 accelerator above formula is for reference, with temperature changes and method of operation, construction speed of different content, curing System should be adjusted during use. First adding curing agent (or accelerator) the preparation, stir then add accelerator (or curing agent) can use sufficient stir. Construction temperature should not be below 15 ℃, relative humidity not higher than 80%. After curing should be at room temperature (20 ℃) ??curing 24 hours, then at 30 ℃, 40 ℃, 80 ℃ for 3 hours each, if no post-processing conditions of high temperature, room temperature curing 28 days should be put into use.
