Expansion Pex Plug Is Deeply Loved

  • PEX Expansion Fittings are commonly known as expansion pipes, expansion plugs, expanded rubber particles, wall plugs, plastic anchors and many other names. Expansion tube should have appeared before the expansion screw. It evolved from the wooden plug into the current plastic expansion plug. After the test of time and environment, the performance of the expansion tube is far better than that of the wooden plug. In order to reduce the extent of cold shrinkage and thermal expansion, the anti-aging effect must be much better than that of wood materials, and the force is good, and the matching size is convenient and standard. In the special environment requirements such as insulation and humidity, it can exert the maximum fastening force for a long time, which is deeply loved by customers.
     The raw material of the expansion pipe is generally soft rubber HDPE (PE for short), which is a kind of thermoplastic resin made by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefin. Polyethylene is non-toxic and tasteless, feels like wax, and has excellent low temperature resistance. Its chemical stability is capable of resisting most acid and alkali corrosion. It is insoluble in general solvents at room temperature, has low water absorption and excellent electrical insulation properties. Or PA6 and PA66 are the trade names of polyamide fibers, and nylon (PA for short), whose basic constituents are injection molding of aliphatic polyamides connected by amide bonds—[NHCO]—. It is characterized by good toughness, not easy to break, and strong bearing capacity. Among them, nylon material is the most widely used variety among the five major engineering plastics.
     The style and classification of expansion pipes: The commonly used expansion pipes are straight-through expansion pipes, and two kinds of fish-shaped expansion pipes. With the expansion and demand of market applications, the styles of expansion pipes are becoming more and more extensive, and their functions It is also more obvious; for example, aircraft-type expansion pipes for ceiling gypsum board, and multi-function knotted expansion pipes for hollow walls and hollow bricks.
     For the installation of expansion pipes, improper installation will affect the installation effect of the product. When installing an expansion pipe, you should first understand the weight of the items to be installed and the hardness of the installation substrate, and then choose a suitable expansion pipe. If you are installing a heavier object, you should choose a large-size expansion tube. In addition, you can choose a variety of length products according to the installation base material, such as non-concrete, porous bricks, etc., and you need to use multiple sizes and longer ones The expansion tube is used to install the fixed object, and the bearing capacity is determined by the focal length and the focal distance.

    Tips for using Expansion PEX Plug:
    1. Drill the prefabricated holes with vertical balance at one time to avoid drilling the same hole multiple times;
    2. Clean the holes, which can be cleaned with wind or water, etc.; clear the residue left when drilling to reduce the sliding of the expansion tube caused by dust to increase the friction;
    3. Avoid repeated use of holes and expansion tubes. Holes used multiple times will be expanded due to expansion when the expansion tube is expanded. If the same hole is used multiple times, it is easy to cause sliding. If the same expansion tube is used multiple times, Causes the expansion tube to break, deform, easily cause the screw to deviate, the fastening force is not good, etc.
