The invention relates to low-moisture-content self-hardening furan resin for casting and a preparation method of the low-moisture-content self-hardening furan resin, and belongs to the technical field of self-hardening furan resines.The self-hardening furan resin is obtained by combining a resin base material with a net-shaped adhesion structure, and the net-shaped adhesion structure is obtained by spraying net-connected adhesive glue on the outer surface of the resin base material. The resin base material is prepared from 65 to 75 parts of furfuryl alcohol resin, 6 to 12 parts of toluenesulfonic acid, 3 to 6 parts of melamine, 8 to 10 parts of phenol and 5 to 10 parts of urea. According to the invention, the peach gum, the rosin and the shellac are all excellent natural adhesives and have good film-forming property and adhesive force, and the resin base material is mixed with the net-connected adhesive glue by adopting the method provided by the invention; compared with the traditional self-hardening furan resin prepared by mixing the resin base material and the net-connected adhesive by adopting a stirring mode of a stirrer, the self-hardening furan resin has the advantages that the physical property is better, and the addition of water in the furan resin can be reduced in the actual use process.

This utility model provides a pine resin heat-insulating and anti-clogging conveying pipeline, relating to the technical field of pine resin conveying devices. It includes a main pipe, which comprises a liquid inlet section, a narrowing section, a throat section, an expanding section, and a liquid outlet section, connected end-to-end and fixed to each other. The narrowing section has a truncated conical structure, with the inner diameter of its input end being the same as that of the liquid inlet section, and the inner diameter of its output end being the same as that of the throat section. A heating mechanism is fixedly installed on the outer wall of the throat section, and an insulation pipe is fixedly installed on the outer sleeve of the main pipe. Through the variable diameter structure of narrowing for acceleration and expanding for flow stabilization, the flow state of the resin is actively optimized. After entering the throat section, the kinetic energy of the resin is significantly increased, breaking the laminar flow state and eliminating the stagnant zone at the pipe wall boundary, preventing impurities from depositing. Combined with precise local heating in the throat section, replacing full-line heating, energy consumption is significantly reduced. The external insulation pipe further suppresses heat loss, effectively solving the pipeline blockage problem caused by temperature decreases during long-distance transport, significantly improving production continuity and reducing maintenance costs.
