To walk the bird, the bird owner needs to take it out for a walk every day, not to stay in one place for a long time, in order to increase its activity.

1. It is very important to measure the galvanized iron wire automatically from the cargo reel to the drum, which is very important to the extension characteristics and working life of galvanized iron wire.

In the rolling process, if the surface of the steel wire is rough, the relative friction coefficient of the steel wire and roll increases, the friction resistance increases, the steel wire elongation decreases, the width increases. In the production of weighted leather material is easy to wide, is because of its rough surface. On the contrary, the surface of the steel wire is smooth, because the friction resistance between the steel wire and the roll is small, it is easy to extend, and the width is small. Domestic steel wire in order to prevent rust, the surface coated with butter, such as butter removal is not clean, easy to slip when rolled flat, also affect its width.

Stainless steel barbed rope in the way of corrosion is not very, because the surface is not treated but rely on its own raw materials for corrosion resistance, so there will be no chemical reaction.

2. Eliminate caked zinc residue on zinc liquid surface

The hard carbon aerogel can maintain the super-elasticity in harsh conditions, such as in liquid nitrogen. Based on the fascinating mechanical properties, this hard carbon aerogel has promise in the application of stress sensors with high stability and wide detective range (50 KPa), as well as stretchable or bendable conductors. This approach holds promise to be extended to make other non-carbon based composite nanofibers and provides a promising way of transforming rigid materials into elastic or flexible materials by designing the nanofibrous microstructures.
