Silicon Features

Santech Applied Technology Co.,Ltd | Updated: Jun 22, 2017

Features of silicon PU

First, the professional: hard on the performance of the bomb, is designed for healthy sports professional structure. One of the important objectives of the construction of the stadium is to provide professional, safe and healthy sports and athletic conditions for sport. Silicon The hard-paced site can bring professional sports texture. With flexible sports ground, it can effectively increase the motion buffer , To reduce the athletes ankle, joints, ligaments due to ground caused by the impact of the reaction; at the same time effectively reduce the movement due to fall or fall caused by movement accidental injury. Hard in the bombs, bombs and not soft professional sports structure.

Second, environmental protection

Implementation of interior decoration materials harmful substances limited national standards: GB18581

1, for the one-component silicone modified polyurethane, water curing, no residual chemical composition.

2, the surface layer of synthetic resin, Silicon water-based materials, recognized environmentally friendly materials.

Silicon PU to become the market recognized health professional golf course materials, depends on the R & D fully take into account the environmental and environmental performance of materials to "national interior decoration materials harmful substances limit" (GB18581) for the test standards, Layer for the one-component silicone modified polyurethane, water curing, no residual chemical composition; Silicon surface layer of water-based materials, recognized health and environmental protection. The National Building Materials Testing Center of the sampling inspection, silicon PU full set of materials in full compliance with the national interior decoration materials harmful substances limited standards, and by the National Environmental Protection Department Certification Center issued by the Chinese environmental labeling product certification (Ⅰ type) Type logo, Silicon into the government green procurement list.

Silicon has the highest theoretical lithium storage capacity and becomes the preferred anode for high energy density lithium ion batteries, yet its low cycle life has seriously hindered its commercial applications. The low cycle life of silicon negatives results from the large volume expansion in the charge and discharge process. The volumetric expansion of the silicon negative electrode makes the mechanical stability of the silicon particles and electrodes, the electrical contact between the active particles and the stability of the SEI film. Silicon In order to improve its cycle stability to change this disadvantage, the researchers in the pole piece of the preparation process, the choice of electrolyte and battery design has done a lot of efforts, Silicon and achieved some success. The research work is reviewed in order to provide feasible technical ideas for the practical process of silicon negative.

The structural design of the silicon material enables a single active particle to remain intact in the repeated volume changes, thereby improving the cycling performance of the material. However, the volumetric expansion of silicon also leads to the mechanical stability of the electrode, Silicon the electrical contact of the active particles within the electrode, and the stability of the SEI film on the electrode surface. Silicon Therefore, the properties of the silicon anode are not only related to the composition and structure of the material itself With the pole piece of the preparation process, the choice of electrolyte and battery design is closely related.
