Problems solved by technology

Many years of use of this product have proved that there are still many problems, such as: because the product is plastic and its thickness is relatively thin, it needs to be wound many times to achieve the sealing effect when it is used. A lot of waste and high cost
Therefore, after many years of use, it has been proved that in order to achieve the sealing effect, first wrap a few turns with raw hemp, and then wrap a few turns of PTFE raw material tape. This kind of sealing effect is the best, and it also reduces the cost. inconvenient

Embodiment 1

[0017] Such as figure 1 The schematic diagram of the cross-sectional structure shown is composed of a substrate layer 1 , a sealant 2 and raw hemp silk 3 . Select the base material layer 1 as the base material on a professional coating machine, coat the sealant 2 on one side, and scrape off the excess sealant 2 with a special scraper to control the coating of the sealant 2 evenly and not less than 15g / m 2 , stick the raw hemp silk 3 with a thickness of 1.0mm on the substrate layer 1 longitudinally, in order to control the distance between the raw hemp silk 3, use a professional convex-concave stick to run the raw hemp silk 3 longitudinally in the concave part of the range of 1.0mm-2.5mm, Compound surface layer 4 on it again. In order to prevent the sealant 2 from sticking to other positions when it is not dry, and causing the raw hemp silk 3 to fall off, the raw hemp silk 3 sticking to the substrate layer 1 is compacted between a professional silica gel roller and a steel rol...

Embodiment 2

[0019] Such as figure 1 The schematic diagram of the cross-sectional structure shown is composed of a substrate layer 1 , a sealant 2 and raw hemp silk 3 . Select the base material layer 1 as the base material on a professional coating machine, coat the sealant 2 on one side, scrape off the excess sealant 2 with a special scraper to control the coating of the sealant 2 evenly and not more than 50g / m 2 , stick the raw hemp silk 3 with a thickness of 2.5mm on the substrate layer 1 longitudinally, in order to control the distance between the raw hemp silk 3, use a professional convex-concave stick to run the raw hemp silk 3 longitudinally in the concave part of the range of 1.0mm-2.5mm, Compound surface layer 4 on it again. In order to prevent the sealant 2 from sticking to other positions when it is not dry, and causing the raw hemp silk 3 to fall off, the raw hemp silk 3 sticking to the substrate layer 1 is compacted between a professional silica gel roller and a steel roller,...

Embodiment 3

[0021] Such as figure 1 The schematic diagram of the cross-sectional structure shown is composed of a substrate layer 1 , a sealant 2 and raw hemp silk 3 . Select substrate layer 1 as the substrate on a professional coating machine, apply sealant 2 on one side, and scrape off excess sealant 2 with a special scraper to control the coating of sealant 2 evenly and at 25g / m 2 , stick the raw hemp silk 3 with a thickness of 1.5mm longitudinally on the substrate layer 1, in order to control the distance between the raw hemp silk 3, use a professional convex-concave stick to run the raw hemp silk 3 longitudinally in the concave part of the range of 1.0mm-2.5mm, Compound surface layer 4 on it again. In order to prevent the sealant 2 from sticking to other positions when it is not dry, and causing the raw hemp silk 3 to fall off, the raw hemp silk 3 sticking to the substrate layer 1 is compacted between a professional silica gel roller and a steel roller, After being continuously pro...

Abstract

The invention relates to a raw material strip, in particular to a synthetic raw material strip suitable for connecting and sealing pipelines. The raw material strip consists of a polytetrafluoroethylene film, sealing rubber and raw flax silk. The polytetrafluoroethylene film is used as a substrate material; and the raw flax silk is vertically stuck on one side of the polytetrafluoroethylene substrate material through coating the raw flax silk to process the raw material strip. As the structural form is adopted, the raw material strip has simple processing and easy operation; and the product achieves good sealing effect, has high tensile strength and low use cost, is farthest convenient for a user, has good social and economic benefits, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to a raw material belt, in particular to a composite raw material belt suitable for sealing when various pipelines are threaded. Background technique [0002] In the past, raw hemp was usually used for the sealing of pipeline connections, especially when winding raw hemp, it needs to be painted and used to achieve a sealing effect. After that, a new type of material, polytetrafluoroethylene raw material tape, came out to replace the original raw hemp. Although the price is higher, it has good practicability. Many years of use of this product have proved that there are still many problems, such as: because the product is plastic and its thickness is relatively thin, it needs to be wound many times to achieve the sealing effect when it is used. A lot of waste and high cost. Therefore, after many years of use, it has been proved that in order to achieve the sealing effect, first wrap a few turns with raw hemp, and then wrap a few t...
