Purpose of plastic expansion pipe:
It is used to fasten the connection and installation of various small and medium-sized pendants. It can be used indoors and outdoors. Avoid lifting heavy objects and heavy equipment to avoid unnecessary losses.
Installation of plastic expansion pipe: generally, the use of self-tapping screws is not limited to the head type, such as: countersunk head self-tapping screws, round head self-tapping screws, large flat head self-tapping screws, outer hexagon socket self-tapping screws, double-head screws, etc. (peripheral accessories: gaskets, screw covers, rubber rings, hooks, etc.) Avoid the use of fast teeth (sharp wood screws) to avoid cutting the expansion pipe body when the screws are forced in. It is recommended to install and use the matching hardened self-tapping screws to exert good friction and achieve the fastening effect.
As the raw material of plastic expansion pipe, the general expansion pipe uses soft rubber HDPE (polyethylene for short), which is a thermoplastic resin prepared by polymerization of ethylene. In industry, it also includes the copolymer of ethylene and a small amount of a-olefin. Polyethylene is odorless, non-toxic, and feels like wax. It has excellent low-temperature resistance, good chemical stability, and can withstand most acid and alkali corrosion. It is insoluble in general solvents at room temperature, with low water absorption and excellent electrical insulation performance. Or PA6, PA66 (nylon is the trade name of polyamide fiber, also known as Nylon). Its English name is Polyamide (PA for short). Its basic component is aliphatic polyamide connected by amide bond - [NHCO] -. Etc. Its characteristic is good toughness. It is not easy to crack and has strong bearing capacity. Among them, nylon is one of the five engineering plastics.
Huanjie expansion tube style and classification: There are two types of expansion tube commonly used by expansion housekeeper: straight-through expansion tube and fish-shaped expansion tube. With the expansion and demand of market application fields, the expansion tube style is also more and more extensive, and its function is more obvious and more powerful. Huanjie's professional styles include ceiling gypsum special expansion pipe (aircraft expansion pipe), and multi-function knotted expansion pipe for air wall hollow brick. The size of the expansion pipe is M4-M16 diameter, and the length is from 20mm to 160mm. The styles include straight expansion pipe, fish-shaped expansion pipe, conical expansion pipe, flange expansion pipe, straight extended expansion pipe, knotted expansion pipe, American expansion pipe, toothed expansion pipe, driven rapid expansion pipe, double-fin fish-shaped expansion pipe, nylon expansion pipe, etc.
