Embodiment Construction
[0018] 1. Wire drawing process section: first set the running speed of the wire drawing furnace at 2 to 3 m / s, and the rotational speed of the drum at 24 to 30 m / s; meanwhile, mix the polyacrylate solution with a solid content of 50% and water at 1 : The ratio of 1.2 is made into solution 40kg;
[0019] Fiberglass consists of 5 # The medium-alkali glass balls are melted and drawn to form glass fibers, and the diameter of the fibers is between 10-15mm; the final fiber weight is about 55-60kg.
[0020] While forming fibers, the polyacrylate solution is evenly sprayed on the glass fibers. After the amount of fibers is reached, a concentrated felt is formed. At this time, the concentrated felt is cut along the axial direction of the roller and spread on a platform. superior.
[0021] 2. Drafting process section: stretch the concentrated felt on the platform horizontally along the cutting direction, and the width of the felt after drafting reaches 1.8-2.3 meters wide.
[0022] 3...
