Insulating Impregnating Paint (Fan Lishui) YQ202B Instructions YQ202B is mainly composed of alkyd resin, hydrocarbon solvents, diluents, driers, leveling agents, etc., and is suitable for medium and low temperature drying and molding. The paint film has high mechanical strength and excellent electrical insulation properties, and is resistant to moisture, water, corrosion and flexion. It is widely used for insulation of transformers, small and medium-sized motor coils, circuit boards, computer parts and other electrical appliances. It is characterized by good overall performance, especially thick layers with good drying properties, good permeability, strong adhesion, and also has anti-rust and arc resistance properties. 1. Technical requirements 1. YQ202B should meet the following requirements: No. Indicator name Indicator 1 Appearance The paint should dissolve evenly, not opacifying, and contain no mechanical impurities. The paint film should be smooth and flat after drying. 2 Viscosity No. 4 viscometer, 251C, 20-50 seconds (or produced according to user requirements) 3 Solid content 1052C, 2 hours, % 423 (or produced according to user requirements) 4 Drying time 802C, hour, 902C, hour 21.55 Acid value mg KOH/g (paint), not more than 66 Thermoelasticity 1502C, hour, not less than 307 Oil resistance less than 1052 In C transformer (10#), hour, no less than 248, heat resistance grade B (130) 9, water absorption %, no more than 210, power frequency breakdown strength, kV/mm, no less than (1) normal state ( 2) After being immersed in water at 205C for 24 hours, 704011 volume resistivity, ohm·cm, shall not be lower than (1) under normal conditions (2) after being immersed in water at 205C for 24 hours (3) 130 2C 2. Test method 1. The performance measurement of paint shall be carried out in accordance with GB1981-80 \"Test Method for Solvent Paint for Electrical Insulation\". 2. Paint film preparation conditions: After the first dip, drip dry for 10-15 minutes and dry at 802C for 1 hour. For the second time, invert the paint at 180 and drip dry for 10-15 minutes, then dry at 802C for 3 hours. 3. Acceptance, packaging, marking, storage and transportation 1. The factory test items are items 1, 2, 3, 4 and 5 in the table in Article 1. 2. Each barrel is packed in 18 liters or 200 liters. 3. The storage period is 4 months. If it expires, it will be inspected according to the standard. If it is qualified, it can still be used. 4. The product should be stored in a clean, dry, well-ventilated warehouse or shed with a temperature of 2035C. It should not be near fire sources, heaters or exposed to direct sunlight. 5. Others should comply with JB-907-80 \"General Rules for Acceptance, Packaging, Marking, Storage and Transportation of Electrical Insulating Paint, Resin and Glue\".
