Embodiment Construction

[0020] The invention is further described below in conjunction with specific embodiments:

[0021] figure 1 It is a schematic diagram of the structure of a traditional sealing bag. The sealing bag includes a bag body 1 and a spacer strip 2. The spacer strip 2 passes through the middle of the bag body 1 to divide the bag body 1 into two parts that are sealed and independent from each other. The bag body 1 Divided into two independent parts, when the spacer strip 2 is drawn out from the bag body 1, the two mutually independent parts in the bag body 1 communicate, wherein the spacer strip 2 is perforated on the bag body 1 by a conventional method.

[0022] refer to figure 2 and Figure 4 On the bag body 1, two filling nozzles 3 respectively connected to two independent parts in the bag body 1 are installed, and a detachable sealing cover 4 is installed on the filling nozzle 3. Preferably, the filling nozzle 3 is arranged on the peripheral edge of the bag body 1, and its inner...

Abstract

The invention discloses a hole sealing bag and a production process thereof. The hole sealing bag includes a bag body and an isolation strip, wherein the isolation strip penetrates through the bag body and divides the bag body into two independent parts; the two independent parts in the bag body communicate with each other when the isolation strip is extracted form the bag body; the bag body is provided with two filling mouths correspondingly communicating with two independent parts; and detachable sealing covers are arranged on the filling mouths. The hole sealing bag effectively solves the technical problems that the packaging workload and difficulty are high in the structure and process of a traditional hole sealing bag, and residual liquid of the bag mouths easily affects the edge sealing of the bag body.

Description

technical field [0001] The invention relates to a sealing bag and a production process thereof, and belongs to the technical field of gas drainage and drainage hole sealing in coal mine tunnels. Background technique [0002] The sealing bag is mainly used for coal seam gas drainage or other gas and liquid drilling plugging, so as to ensure the sealing between the outer wall of the gas or other gas and liquid drainage pipe and the hole wall. The sealing bag is a long strip bag, separated by a spacer in the middle. When in use, the spacer is pulled out to connect the two separated parts. After the two components of the polyurethane material in the bag are fully mixed quickly, the polyurethane material passes through The chemical reaction expands and solidifies to seal the seal. [0003] refer to figure 1 , the structure of existing sealing bag is: the middle of encapsulation elongated bag is blocked with spacer strip, and all carries out edge sealing all around. When fillin...
