The purpose of plastic expansion tube:
Used for connecting and installing various small and medium-sized pendant items. Can be used both indoors and outdoors. Avoid using it for lifting heavy objects or heavy machinery to prevent unnecessary damage.
Installation of plastic expansion pipe:Generally, self tapping screws are required, and the head type is not limited, such as countersunk self tapping screws, round head self tapping screws, large flat head self tapping screws, outer hexagonal and inner hexagonal self tapping screws, double headed screws, etc. (peripheral accessories: gaskets, screw covers, rubber rings, hooks, etc.) Avoid using quick teeth (such as sharp wood screws) to prevent the screws from cutting off the expansion tube body when forced in. It is recommended to install and use hardened self tapping screws to enhance friction and achieve a better fastening effect.
Raw materials for plastic expansion pipes：The general expansion pipe adopts 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 odorless, non-toxic, feels like wax, has excellent low temperature resistance, good chemical stability, and can withstand most acid and alkali corrosion. Insoluble in general solvents at room temperature, with low water absorption and excellent electrical insulation performance. ）Or PA6, PA66 (Nylon is the trade name for polyamide fiber, also known as Nylon. The English name is Polyamide (abbreviated as PA), and its basic component is an aliphatic polyamide connected by amide bonds - [NHCO] -. ）Waiting for injection molding. Its characteristics are good toughness, not easy to break, and strong load-bearing capacity. Among them, nylon material is a widely used variety among the five major engineering plastics.
Style and classification of Huanjie expansion tube:The commonly used types of 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. The professional styles of Huanjie include expansion pipes for ceiling gypsum boards (airplane type expansion pipes), as well as multifunctional bonded expansion pipes 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.
