Linings of FRP store and reserve tanks, concrete pools, metal shells (interior and exterior), adopts anti-corrosion resins and glass fiber surface felt as anti-corrosion layers, and takes unsaturated polyester resins and middle alkali glass fiber cloth as reinforcing layers. Products with the linings have high anti-corrosion, good strength and long using life span, widely used in store tanks, acid washing tanks and ion exchangers in electric power, metallurgy, petroleum, chemical, printing, mechanical, environmental, and other industries.
I¡¢linings based on epoxy, furan, polyester and phenol aldehyde: linings based on epoxy, furan, polyester and phenol aldehyde all are made by hand lay-up molding. According to different temperatures and pressures of the media, select different raw materials. Features: strong adhesion strength, low cost, simple process, good anti-corrosion property, uniform colors, good integrity, aging , abrasion and impact resistance, and pressure standing. When using of linings of epoxy, furan, polyester and phenol aldehyde, use epoxy resin as spraying or brushing primer to enable solid of substrate adhesion, no matter the surfaces are metal or concrete ones. Physical properties: compressive strength 3000kg/cm2, impact strength 265kg/cm2. the linings are widely used in anti-corrosion and leaking stoppage engineering in chemical, pharmaceutical, electric power plants, communication, metallurgy and shipbuilding industries.
II¡¢Rubber linings: rubber linings are rubber plates lined compatibly on metal devices, which become cured rubber linings through steaming and vulcanizing. They separates media from a lot of surfaces to act an anti-corrosive function. They can stand normal non-oxidizing strong acids, organic acids, and alkali or salt solution. Mechanical properties£ºtensile strength 240-300kg/cm2£¬relative elongation rate 550--650%, permanent distortion 20--30%, no-corrosion under function of 36% hydrochloric acid at 80¡æ. The biggest advantage of rubber linings is that they overcome the defect of insufficiency of inner stress of metals. There is no dropping off for the linings, but with strong adhesive force. They are a kind of anti-corrosion linings which couldn¡¯t be short for chemical, pharmaceutical, colorful metallurgy and food processing industries.
III¡¢resin glue mud for paving block materials and filling gaps£º£©: resin glue mud for paving block materials and filling gaps is a kind of material for paving tiles, porcelain plates, pottery plates and marble bars on substrates of concrete or metals by using of resin mud. The specific process is that: coat epoxy resin a on a substrate firstly, then pave with resin mud after drying. Features are high temperature, acid and alkali resistance, strong adhesive force, available for multi-layer paving. They are mainly used in anti-corrosion for chemical, pharmaceutical and metallurgy industries.
FRP Corrosion Resistant Store Tanks
FRP corrosion resistant store tanks produced by our company could meet special requirements of users, with height from 2m to 15m£¬and corrosion to acids and alkalis.
I. Fundamental Features
£ªExcellent physical properties£ºspecific gravity of FRP normally is 1.8-2.1£¬1/4-1/5 of that of steel£¬with higher specific strength than steel, cast iron and plastics. Coefficient of thermal expansion of FRP is equivalent to that of steel, however, coefficient of thermal conduction is only 0.5% of that of steel.
£ªchemical corrosion resistance, long using life span£ºFRP has special corrosion resistant property. For storing corrosive media, FRP displays unmatchable superiority to other materials, anti-corrosive to many acids, alkalis, salts and organic solvents.
£ªlarge design flexibility, excellent structural property of tank walls£º£¬to meet requirements of different media and working conditions. Adjust tank loading capability by structural layer thickness, winding angle, wall thickness and design, to manufacture FRP store tanks and non-standard equipment with different pressure grades or special functions. This is unmatchable for metal materials which have same property in all directions.
II. Key Manufacturing Process
Controlled by computer, prepare inner lining layer ( for example anti-corrosion inner lining layers) on core models, after gelling, wind structural layers according to designed line styles and thicknesses, make outside protective layers finally.
III. Raw and auxiliary materials
resin, fiber felt, FRP wound yarn, etc.
