Construction process and key points of chlorosulfonated polyethylene paint 1> Primer application: Apply the primer evenly on the treated substrate surface; there should be no defects such as missed areas or sagging, and natural curing should take at least 24 hours. 2> Repair layer: In the uneven areas of the base layer, resin mortar should be used for repair and leveling; natural curing should take at least 24 hours. The base layer should be smoothed using resin mortar after repair. 3> The construction of resin-fiberglass lining layers using the intermittent method shall comply with the following provisions: 1. Glass fiber cloth shall be trimmed, and polyester cloth shall undergo anti-shrinking pretreatment. 2. First, apply a uniform layer of adhesive material, then cover it with a layer of fiber-reinforced material; it is essential to ensure a tight fit and to remove any bubbles. After that, apply another layer of adhesive material, making sure it is fully filled in. 3. It should be cured for 24 hours; after the surface is trimmed, the subsequent layers should be applied following the procedure outlined above, until the desired number of layers or thickness is achieved. 4. After each layer is laid, the quality of the previous layer should be checked; if defects such as burrs, delamination, and bubbles are present, repairs should be made. 5. During laying, the overlap width of fiber reinforcement materials in the same layer should not be less than 50 mm, and the joints of fiber reinforcement materials in the upper and lower layers should be offset from each other, with the offset distance being no less than 50 mm. One to two layers of fiber reinforcement material should be added at the corners. Article source: www.qryqtl.com Original URL: http://www.qryqtl.com/shownews.asp?id=303
