Phenolic Laminated Cotton Cloth Board

3025, 3026, 3027, 3028 phenolic laminated cotton cloth board which is a kind of insulation materials:
The 3025 board is made of cotton cloth (coarse) impregnated with phenolic resin and hot pressed. It has high mechanical properties, especially high bonding strength, suitable for insulating structural parts in machinery, motors, electrical equipment, and can be used in transformer oil.
The 3026 board is made of cotton cloth (fine) impregnated with phenolic resin and hot pressed. The product has high mechanical properties and is suitable for rotating anti-vibration and wear-resistant parts of mechanical equipment.
The 3027 board is made of cotton cloth (coarse) impregnated with phenolic resin and hot pressed. The product has high mechanical properties and is suitable for insulating structural parts in machinery, motors and electrical equipment, and can be used in transformer oil. The electrical performance is better than 3025 board.
3028 board is made of cotton cloth (fine) impregnated with phenolic resin and hot pressed. The mechanical properties of the product are the same as 3026, but the electrical properties are better than 3026 and can be used as small parts.

The insulation heat resistance of this series of Phenolic laminated cotton cloth board is E grade (120 ℃).
experimental method:
(1) Measurement of appearance: observe and evaluate with eyes.
(2)Determination of density: According to the method A of GB / T1033.
(3) Determination of other items: according to GB / T5130.
Application tips of Phenolic laminated cotton cloth board:
(1) The properties of laminate and metal are different, and the processing should be carried out in accordance with JB / Z141 “Mechanical Processing Method of Insulating Laminate Products”.
(2) Due to the low thermal conductivity of the laminate, a small feed and high cutting speed should be used during machining.
(3) The laminate is easy to absorb moisture after processing, it is best to dip the insulating paint for moisture treatment.
(3)Laminates are prone to produce large amounts of dust and odor during mechanical processing, so ventilation and dust removal and worker labor protection or dust suction devices should be strengthened.

Precautions of Phenolic laminated cotton cloth board:
(1) The product is highly hygroscopic and should be stored in a dry, well-ventilated environment during storage.
(2)The product is damp during storage and machining, so it should be baked at low temperature.
(3) The product is stored for 1 year. If it exceeds the storage period, it can still be used after passing the inspection.
