Recently, Tejnoji Mika of Italy developed a Teflon wine bottle stopper, which has more advantages than the commonly used wine bottle stopper. This Teflon wine cork is covered with a layer of fine powder of polytetrafluoroethylene polymer produced by DuPont in the surface of an ordinary wine stopper. The smooth, non-chemical polymer stoppers are easy to plug, easy to pull out, and better prevent the release of alcohol in the bottle. Therefore, it does not affect the taste and mellowness of the wine. The PTFE membrane layer outside the stopper can also resist the erosion of any solution.

Detailed introduction:
Photovoltaic solar spiral pile is a kind of spiral drilling pile. Its characteristics include the connection of drill bit and drill pipe, drill bit or drill pipe connecting a power source. After this photovoltaic solar spiral pile is placed underground, it will no longer Take it out and use it directly as a pile.
The drill bit of the photovoltaic solar spiral pile includes the spiral drill bit at the bottom.
Specific structure:
1. Use steel pipe in the middle part
2. The top is the connecting pipe
3. The drill pipe of the photovoltaic solar spiral pile includes the upper connecting pipe
4. Steel rod in the middle part
5. The lower connecting shaft
6. After the pile is driven into the ground, it is no longer taken out, but used as a pile directly.
On the basis of the "end-bearing pile" structure and "friction pile" structure used in the construction process, it is widely used in the construction of a variety of ground piles, ground anchors, and randomly structured ground piles.
