Abstract

The present invention relates to a PP tape yarn pipe for loading an explosive. A PP tape yarn is selected as a warp yarn and a weft yarn to be supplied to a circular knitting machine and to knit in the shape of a pipe. Placed is a conductive carbon yarn, which is made by mixing conductive carbon with the PP tape yarn with an interval of 4-6 cm in the direction of the warp yarn. Thus, the knitted pipe has a function for preventing static electricity and a waterproof function by coating the whole internal surface with a synthetic resin film. The pipe of the present invention is made to be flat by forming a folded unit, which is made by folding both side walls of a tube-shaped knitted material in the shape of V to face each other inward, and folding for the front surface and the rear surface to come in contact. The present invention aims to remove the inconvenience that an inserted explosive explodes due to an action of static electricity in accordance with the surrounding environment.

Description

Explosive loading PP tape pipe for explosives loading {

The present invention relates to a PP tape pipe body for an explosive charge, which is used for drilling a hole in a blasting position and for carrying explosives when performing blasting with explosives in a construction site such as a tunnel construction, a digging construction, or a light engineering construction. More specifically, PP tape yarns are selected as light and weft yarns and fed to a circular knitting machine, knitted in a tubular shape, and spaced at regular intervals in the oblique direction, and conductive carbon yarn in which conductive carbon is mixed with PP tape yarns is knitted and knitted, It is coated with a synthetic resin film on the entire inner surface to provide a waterproof function, and both sides of the tube are folded into a ∨ shape to face each other from the outside to the inside to form a flat shape so that the front side and the back side are in contact with each other. It is possible to supply the tube for charge of explosives.

Conventional explosion-proof container has an air tube, which is not only expensive but also inconvenient to handle and has no antistatic function. Therefore, the explosive charged in accordance with the surrounding environment has an inconvenience to cause a safety accident by explosion without warning due to the action of static electricity

The present invention has been developed in order to solve the above inconvenience.

The present invention relates to a knitted fabric comprising a PP knitted fabric made by knitting a PP tape yarn into warp and weft yarns and knitting the yarn into a tubular shape and mixing the conductive carbon with a PP tape yarn at intervals of 4 to 6 cm in an oblique direction, And the waterproof function is provided by coating a synthetic resin film on the entire inner surface of the tubular body, and a folded portion formed by folding the both side walls of the tubular knitted fabric from the outer side to the inner side is formed to form a folded portion, So that a flat tubular body contacting each other is formed.

In the present invention as described above, a synthetic resin film is coated on an inner surface of a knitted fabric knitted in a tubular shape using a PP tape yarn at regular intervals in an oblique direction, and a transverse folded portion By forming, the tube is made flat and convenient to handle, it has waterproof function and anti-static function, so it cuts the tube into a certain length and seals the cut part. When it expands, it forms a cylindrical waterproof container. There is an advantage in that the body has an antistatic function and the advantage that the explosive charged in the inside can be exploded safely due to the static electricity can be prevented so that the explosive can be handled securely, We can supply safe products for explosives.

Claims (1)

A PP tape yarn was selected as warp yarns 1 and weft yarns 2 and fed to a circular knitting machine to knit a tubular knitted fabric P but to combine the conductive carbon with a PP tape yarn at a position of 4 to 6 cm in an oblique direction The knitted tubular body is provided with the antistatic function and the synthetic resin film 4 is coated on the inner surface to provide a waterproof function by disposing the car head company 3 and the two side walls of the tube- Folded portion (P ') so that the tubular body is folded so that the front surface and the back surface thereof are in contact with each other to form a flat tubular body.
