The commonly used expansion tubes include straight through expansion tubes and fish shaped expansion tubes. With the expansion and demand of the market, the styles of expansion tubes are becoming more and more diverse, and their functions are becoming more obvious and powerful. There are various types of expansion pipes, such as those specifically designed for ceiling gypsum boards (airplane type expansion pipes), as well as multifunctional bonded expansion pipes used for hollow walls and hollow bricks. The sizes of Huanjie expansion tubes are M4-M16 diameter, with lengths ranging from 20mm to 160mm. The styles include straight expansion tubes, fish shaped expansion tubes, conical expansion tubes, flange expansion tubes, straight extended expansion tubes, tied expansion tubes, American expansion tubes, toothed expansion tubes, driven rapid expansion tubes, biplane fish shaped expansion tubes, nylon expansion tubes, etc.
As we know, plastic expansion pipes are injection molded from PE material. Mainly used for house decoration, fixing cable trays, fixing switches, sockets, lighting fixtures, etc. Also use industrial machinery where screws are needed to secure the connecting parts. But do you know how to better utilize the expansion tube? What are some tips for using expansion tubes? Briefly introduce the usage techniques of the expansion tube.
1. Drill the prefabricated holes vertically and evenly at once to avoid drilling the same hole multiple times.
2. Cleaning the borehole can be done by blowing air, cleaning with water, or sweeping with a brush to remove any residue left during drilling, in order to reduce the sliding caused by dust on the expansion tube and increase friction.
3. Avoid reusing holes and expansion tubes, as holes that are used multiple times may become stretched due to expansion during the previous expansion of the expansion tube. Using the same hole multiple times can cause sliding, and using the same expansion tube multiple times can cause the expansion tube to break, deform, and result in screw misalignment and poor fastening force
4. For novice installation, you can choose an expansion tube with a relatively thicker wall thickness to avoid damage and loose installation during installation.
Plastic expansion tubes are commonly referred to as expansion tubes, expansion plugs, expansion rubber particles, wall plugs, plastic anchor bolts, and various other names. The expansion pipe should have appeared before the expansion screw. It has evolved from the basis of the wooden plug to the plastic expansion plug. After the test of time and environment, the performance of the expansion pipe is far better than the wooden plug. To reduce the range of cold shrinkage and thermal expansion, it is also better than the wooden material in terms of anti-aging effect. It is also convenient and standard in terms of stress and matching size. It can exert strong fastening force for a long time in special environmental requirements such as insulation and humidity, thus gaining the favor of customers.
The raw material for expansion pipes is generally soft adhesive HDPE (polyethylene, abbreviated as PE), which is a thermoplastic resin made by polymerizing ethylene. In industry, it also includes copolymers of ethylene with small amounts of alpha olefins. Polyethylene is non-toxic and odorless, feels like wax, and has excellent low-temperature resistance. Its chemical stability is excellent, and it can withstand most acid-base erosion. Insoluble in general solvents at room temperature, with low water absorption and excellent electrical insulation performance. Or PA6, PA66 is the trade name for polyamide fiber, also known as nylon (abbreviated as PA), whose basic components are injection molded aliphatic polyamides connected by amide bonds - [NHCO] -. Its characteristics are good toughness, not easy to break, and strong load-bearing capacity. Nylon material is a widely used variety among the five major engineering plastics.
