Expansion tubes are commonly used in straight expansion tubes and fish expansion tubes. With the expansion and demand of the market, the styles of expansion tubes are more and more extensive, and their functions are more obvious and more powerful.Such as ceiling gypsum board special expansion tube (aircraft expansion tube), as well as hollow wall hollow brick with multi-functional knotted expansion tube and so on.Annular expansion tube size is M4-M16 diameter, length from 20mm to 160mm.There are straight expansion tube, fish expansion tube, conical expansion tube, flange expansion tube, straight extension expansion tube, knotted expansion tube, American expansion tube, tooth expansion tube, drive type rapid expansion tube, double fin expansion tube, nylon expansion tube and so on.

As we know, the plastic expansion tube is made of PE material by injection molding.Mainly used for house decoration, fixed slot, fixed switch, socket lighting and so on.Industrial machinery is also used where screws are needed to tighten the connectors.But do you know how to make better use of the expansion tube?What are some tips for using an expansion tube?A brief introduction to the use of expansion tube skills.

1. Drill the prefabricated hole in a one-time vertical balance to avoid repeatedly drilling the same hole.

2, cleaning holes, cleaning can be blown by the wind, or water, with hair sweep, remove the residue left when drilling, in order to reduce the dust caused by sliding expansion tube, in order to increase the friction.

3. Avoid the repeated use of holes and expansion tubes. The holes used for many times will be expanded and tensioning during the previous expansion of the expansion tube.The.

4, novice installation, you can choose a relatively thick wall of the expansion tube, so as not to cause damage and installation is not strong phenomenon.

Plastic expansion tube commonly known as expansion tube, expansion plug, expansion rubber, wall plug, plastic anchor bolt and other names.Expansion tube should be in the expansion screw before, it is the foundation of the cork stage into the current plastic expansion plug, after the test of time and environment, the performance of the expansion tube is far better than the wood, to reduce the range of cold shrinkage and thermal expansion, in the effect of anti-aging is also better than the wood quality, and in the force, and matching size is convenient and standard.In insulation and humidity and other special environmental requirements can play a long time of fastening force, so as to win the majority of customers love.

The raw material of the expansion tube is generally soft adhesive HDPE (polyethylene for short PE), which is a thermoplastic resin made of ethylene by polymerization.In industry, the copolymer of ethylene with a small amount of alpha-olefin is also included.Polyethylene is non-toxic and odorless, feel like wax, has excellent low temperature resistance, its chemical stability, can resist most acid and base erosion.Insoluble in general solvents at room temperature, small water absorption performance, good electrical insulation performance.Or PA6, PA66 is the trade name of polyamide fiber, and nylon (PA for short), its basic composition is through the amide bond - [NHCO] - aliphatic polyamide and other injection molding connected.It is characterized by good toughness, not easy to break, strong bearing capacity.Nylon material is widely used in five engineering plastics.
