A METHED OF VERTICAL IMMERSION RECIPROCATION TYPE FOR REQUID RESINS ON THE TEXTILE REINFORCE PE TUBE INSIDE.

摘要

A method for impregnating a PE(Polyethylene) non-woven fabric tube with vertical immersion reciprocating resin liquid is provided to impregnate the tube with resin liquid easily in the construction site by making the size of an impregnation apparatus small and to reduce the cost for restraining curing of the resin liquid after impregnating the tube with resin liquid and the transportation cost for a long distance. In a method for impregnating a PE non-woven fabric tube with vertical immersion reciprocating resin liquid, a half of the amount of resin liquid to be used in impregnating the inside of the PE non-woven fabric tube with the resin liquid is stored in the tube through an inlet formed at one end of the tube. The tube is installed at a roller set having a roller(5a) disposed at one roller supporting frame(4a). Resin liquid is filled into a vertical immersion part of the tube. The actual used amount of the resin liquid per unit impregnation length of the tube is calculated by impregnating the tube with the resin liquid in a forward direction. The amount of the resin liquid for the rest unimpregnated tube is stored in the tube through an inlet formed on the other side of the tube. The tube is installed at a roller set having a roller(5b) disposed at another roller supporting frame(4b). And then, the resin liquid is filled into the vertical immersion part of the tube. The rest unimpregnated tube is impregnated with resin liquid by moving the roller in a backward direction. Therefore, the tube is impregnated with resin liquid through both ends of the tube.
