The purpose of plastic expansion pipes:
Used for fastening the connections and installation of various small and medium-sized hanging items. Can be used indoors and outdoors. Avoid using it for heavy objects and heavy machinery to avoid unnecessary losses
Installation of plastic expansion pipes: Generally, self tapping screws are required. The use of head types is not limited, such as countersunk self tapping screws, round head self tapping screws, large flat head self tapping screws, external hexagonal and internal hexagonal self tapping screws, double head screws, etc. (peripheral accessories: mouth pieces, screw covers, rubber rings, hooks, etc.) Avoid using quick teeth (sharp wooden screws) to prevent the screws from cutting off the expansion pipe body when forced in. It is recommended to install and use hardened self tapping screws to maximize friction and achieve the best fastening effect
The raw material for plastic expansion pipes is generally soft adhesive HDPE (polyethylene, abbreviated as PE), which is a thermoplastic resin produced by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of a-ene. Polyethylene is odorless, non-toxic, and feels like wax to the touch. It has excellent low-temperature resistance, good chemical stability, and can withstand most acids and alkalis
At room temperature, it is insoluble in general solvents, has low water absorption, and excellent electrical insulation performance Or PA6, PA66 (Nylon is the trade name for polyamide fibers, also known as Nylon). English name Polyamide (abbreviated as PA), its basic component is an aliphatic polyamide connected by amide bonds - [NHC0] - Waiting for injection molding. Its characteristic is good toughness and not easy to break, Strong load-bearing capacity. Nylon material is the most widely used variety among the five major engineering plastics
Style and classification of Huanjie expansion pipes: The commonly used types of expansion pipes in household regulations are straight through expansion pipes and 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 are becoming more obvious and powerful. There are various types of professional styles of Huanjie, including expansion pipes specifically designed for ceiling stone slabs (airplane type expansion pipes), as well as multifunctional knotted expansion pipes for hollow wall and hollow bricks. The size of Huanjie expansion pipe is M4-M16 diameter, with lengths ranging from 20mm to 160mm. The styles include straight through expansion pipe, fish shaped expansion pipe, conical expansion pipe, flange expansion pipe, straight through extended expansion pipe, knotted expansion pipe, American expansion pipe, toothed expansion pipe, driven rapid expansion pipe, double wing fish shaped expansion pipe, nylon expansion pipe, etc
