Description
Technical Field
The invention belongs to the field of deep pipeline thread sealing materials, and particularly relates to a deep thread sealing grout line and a manufacturing method and a manufacturing device thereof.
Background
At present, the widely applied sealing materials in pipeline thread sealing are anaerobic pipeline thread sealing glue, polytetrafluoroethylene raw material belts and thread sealing lines.
However, anaerobic thread sealants have the following disadvantages in the actual installation process: 1. the anaerobic adhesive only has a curing effect on metal; 2. because metal pipelines need to be threaded by a thread forming machine and need to be cooled by lubricating oil or water in the process, the threads are adhered with impurities of the lubricating oil or water, oil stains need to be cleaned when anaerobic adhesive is installed, and the installation efficiency is influenced by increasing the workload; 3. anaerobic thread sealant installation requires up to 24 hours of complete curing (e.g., longer curing time at low air temperature); 4. for example, when the anaerobic thread sealing glue is used for installing the pipe fittings, the residues need to be further treated when the pipe fittings need to be disassembled so as to be installed again.
The raw material belt has the following problems: 1. the existing new pipeline with the depth has sharp tooth lines, and the thread seal tape is cut and damaged during installation, so that the installation and sealing effects of the product are influenced; 2. due to the depth and the height of the thread pitch of the existing large-caliber thread, the sealing effect of the thread seal tape is difficult to achieve and the thread seal tape is very inconvenient to wind; 3. the residues in the use process of the raw material belt are difficult to degrade in nature, so that the environment is polluted.
In contrast, thread sealing lines can avoid the above problems and deficiencies, but existing thread sealing lines also suffer from the following deficiencies: 1. the viscose glue is not uniform on the fiber line; 2. the adhesive force of the sealing line in the thread winding process is insufficient, so that the construction efficiency is influenced; 3. the wettability of the adhesive decreases with time, and the ideal use effect cannot be achieved.
