Plastic expansion Tube Source:

1. Plastic expansion tube, from the plastic era, some people used plastic column instead of wood carving (wooden plug). With the changes of the times, the wall of the building became harder and more solid from the top of the earth wall, from the original iron nail solid, it has been unable to achieve a safe fastening effect. However, it is installed with wooden plug, which is easy to age, and the cold shrinkage and thermal expansion cannot achieve a long-term fastening effect. However, plastic plugs installed on various base materials can effectively improve the shortcomings of wood materials. At the same time, the density, shrinkage and toughness of plastics are more accurate than those of wood materials, and the shape structure can also be ever-changing. It can produce special shapes according to application occasion and has unique expansion pipe. If hardware fastening is the rice of industry, then plastic expansion tube is the dish of industry.

2. Generally, injection molding and injection molding are adopted. There are two processing methods. The modeling style of agent-plastic expansion pipe is limited. Most of the plastic expansion tube expansion pipe are injection molding. Generally, PE,PA and PP plastics are used as raw materials.

Plastic expansion tube, also called plastic expansion tube screws, is called from different places, commonly known as different, the north is mainly called expansion pipe, the South (Guangdong area) is used to call more than colloidal particle or expansion colloidal particle.

3. English name: wall plug,Expansion pipe plastic Expansion tube fastening needs to be completed with screws. Plastic expansion tube the correct matching is self-tapping screws with coarse teeth. Why is it recommended to use coarse teeth, because its fast teeth self-tapping screws are easy to cut into expansion pipe bodies, and even cut off expansion pipe, which does not achieve the best expansion effect.

4. Plastic expansion tube self-tapping screws can be matched, including outer hexagon self-tapping screws, cross countersunk head self-tapping screws, coiled hair self-tapping screws, outer hexagon self-tapping screws, large flat head self-tapping screws, etc., with unlimited materials. Applied to sanitary ware, stainless steel self-tapping screw should be selected in humid places.

5. Ring Jie plastic expansion tube size:

6. Diameter M5,M6,M7,M8,M10,M12,M14, length ranging from 20mm to 160mm or even more than 200mm. Common sizes are M6 * 30mm,M8 * 40mm,M10 * 50mm,M12 * 60mm.

7. Huanjie plastic expansion tube is divided into civil plastic expansion tube and industrial plastic expansion tube.

8. Ni uses expansion pipe for general home decoration, supporting and connecting small objects. Industrial Plastic expansion tube, there are special-shaped, fixed base materials (such as chopsticks board, hollow wall, ceiling, gypsum board) there are large, used for heavy objects strong. Such as bracket, machinery, etc.
