Silicon PU is a kind of healthy professional elastic synthetic ball scene material system that meets the ergonomic principles and meets the physical and physical characteristics of sports. It has the features of the hard under bullet structure and can be directly constructed on the basis of cement or asphalt. Silicon-modified polyurethane composition buffered rebound structure, two-component modified acrylic as wear-resistant surface layer, by the Jiangmen Changhe Group in January 2005 successfully developed, and named "silicone PU." Here's a look at the origin of silicon PU , silicon pu manufacturers Tips: construction safety precautions.
Silicon PU Overview
As a ground material for sports facilities, it has good cushioning and ductility, strong adhesive force, certain healing function to the foundation, automatic leveling, simple construction, excellent anti-aging properties, and stable chemical performance after construction. Not easy to produce bubbles and other issues.
The origin of silicon PU
In the 21st century, colored court paints represented by acrylics and PUs introduced abroad have gradually emerged in the Chinese sports market. Acrylic has become a designated venue material for the International Union of Tennis because of its colorful and effective suede texture: Its high elasticity characteristics have won a certain market share. But the acrylic must be laid on the asphalt base surface, the surface is easy to sand removal, color change, and lack of sufficient elasticity to make the venue safe, insufficient protection performance; while the PU shines in the sun surface, sticky and lack of sports texture, and Accompanied by a pungent odor. The flaws in these materials prompted the market to look forward to the emergence of a truly new type of material with professional sports texture and health and environmental protection.
In the late 1990s, silicone-modified polyurethane materials were widely used in the field of waterproofing and chemical industry. In 2005, the sports flooring market introduced a silicone-modified polyurethane elastic stadium floor material with excellent structural characteristics to create a revolution in recreation and construction sites. The classic name of the epoch-making new material product, silicon PU, has proved that the silicon PU has excellent advantages in preventing cracking, bulging, and aging of the stadium.
Professional Silicon PU Stadium Construction and Usage Notes:
First, the base surface treatment
The site will be cleaned before construction, curing curing period of not less than 20 days.
Second, laying an elastic layer
Use TB-002 (add solvent to adjust construction consistency), use flat scraper or scraper to lay on the base surface, the thickness of each pavement can't exceed 1.5mm, and each dry interval prevails before the laying interval (generally about 10 Hours, depending on weather conditions on site, until laid to the required thickness. Note: After the elastic layer is laid and solidified, the flatness of the ground shall be tested by the stagnant water method. The water level shall be filled and then the reinforcement layer shall be laid.
Third, laying a reinforcement layer
With TB-003 (add solvent to adjust the construction consistency), two layers of squeegee are laid about 0.8mm thick on the elastic surface, and the surface after laying is required to be smooth and smooth.
Fourth, laying a wear-resistant surface layer
According to TB-205A component: B component: special sand = 9:1:5 is fully mixed and mixed uniformly, laid on the reinforced surface, and two pavements are generally laid. (Smooth surface without special sand)
Fifth, marking
Measure according to the standard size, mark the position of the line with canvas line, and then stick the masking paper along the canvas line on the golf course. Use a special marking paint TB-207 in proportion to the A component: B component = 10:1 fully Blend evenly with a brush between the two textured papers. After the material is dry, remove the textured paper.
Silicon PU Stadium Notes:
1. It takes more than 28 days for the new concrete site to cure and solidify before laying materials;
2. When mixing materials must be fully stirred and uniform;
3, to ensure that the ground is dry before laying the primer;
4. Construction cannot be carried out on rainy days, and construction under conditions of heavy sunlight or humidity greater than 90% can be avoided.
5, indoor venues should maintain good convection ventilation effects;
6. The finish material must be kept for at least 10 hours without water soaking, and the low temperature will take longer;
7. After the site is laid, it must be kept for more than 5 days before it can be put into use.
Conclusion: The relevant information on construction safety precautions was introduced here for everyone. I hope this article will be helpful to everyone.
