Problems solved by technology

[0003] However, the anaerobic thread sealant has the following deficiencies in the actual installation process: 1. The anaerobic adhesive only cures the metal; Cooling with lubricating oil or water will cause impurities of lubricating oil or water to adhere to the teeth. The installation of anaerobic adhesive needs to clean the oil, which will increase the workload and affect the installation efficiency; 3. The installation of anaerobic thread sealant requires up to 24 hours to fully cure (If the temperature is low, the curing time will be longer); 4. If the pipe fittings installed with anaerobic thread sealant need to be disassembled, the residue needs to be further processed before reinstallation
[0004] The following problems exist in the raw material belt: 1. For the current new deep pipe thread is relatively sharp, the raw material belt is cut and damaged during installation, which affects the installation and sealing effect of the product; 2. Due to the current large-diameter thread pitch depth and height , the sealing effect of using raw material tape is also difficult to meet the sealing requirements and winding is also very inconvenient; 3. The residues during the use of raw material tape are difficult to degrade in nature, causing environmental pollution
[0005] In contrast, the thread sealing wire can avoid the above-mentioned problems and deficiencies, but the existing thread sealing wire still has the following deficiencies: 1. The viscose glue is unevenly glued on the fiber thread; Insufficient combined force affects construction efficiency; 3. The wettability of the adhesive decreases with time, and the ideal use effect cannot be achieved

Abstract

The invention is applicable to the field of deep pipeline thread sealing materials, and provides a deep thread sealing slurry line and a manufacturing method and device thereof. The manufacturing method of the deep thread sealing slurry line comprises the following step that slurry is extruded to be applied to chemical fiber filaments, and thus the deep thread sealing slurry line is obtained; wherein the slurry is prepared from the following components in parts by weight: 40-45 parts of dimethyl silicone oil, 30-35 parts of talcum powder, 5-10 parts of white carbon black and 5-10 parts of hydroxypropyl methyl cellulose. The thread sealing slurry line with high viscosity, high strength and excellent sealing performance is prepared by coating the chemical fiber filaments with corresponding slurry, has the characteristics of wear resistance, self-lubricating property, high and low temperature resistance, aging resistance and corrosion resistance, can be used for a long time within a widetemperature range, and is not cured within the temperature range, so that the original viscosity and self-lubricating property are maintained, and the better adhesion is realized in the mounting process.
