Silicon PU is a new generation of golf course materials developed on the basis of PU golf materials. It is a combination of polyethylene materials and materials containing silicone components. It fundamentally and effectively solves the problem that PU golf materials are easy to foam. The lack of environmental protection construction, service life, daily maintenance, etc., with revolutionary innovative performance, is a new generation of environmentally friendly products that replace the two-component PU.
Precautions for the construction of silicon pu materials:
1. When mixing materials, weigh accurately and stir evenly. b. The surface of the construction process must be cleaned before each process. c. Indoor venues must ensure good ventilation.
2. After the site is laid, it must be kept for more than 5 days before it can be put into use.
Silicon pu stadium construction common problems and professional treatment methods
Bubbles appear in the construction of silicon PU stadium:
Phenomenon: Air bubbles are present in the paint film.
Cause: The coating forms air or solvent volatilized gas during the construction process to cause air bubbles, improper handling of the substrate (such as high moisture content of the wood, pores are not closed or water on the surface of the substrate), or improper application during painting (lacquer) This phenomenon is likely to occur when the film is too thick or the like.
Treatment method: The surface of the substrate should be cleaned, the moisture content of the substrate should not be too high, and the high temperature resistant paint should have water on the surface of the substrate, and then the paint should be dried after the water stains dry. If air bubbles have already formed, use a spatula to remove the air bubbles and re-polish the paint.
Pinholes appear in the construction of silicon pu stadium:
Phenomenon: There are pores similar to needles in the paint film.
Cause: The air bubbles mixed in the wet paint film and other air bubbles generated are broken, and cannot be leveled before the paint film is dried. It may also be caused by improper handling of the substrate or improper application of the paint (the film is too thick, etc.). Caused. When the latex paint is applied, the brush is too thick or the drum rotates too fast, and pinholes are easily generated.
Treatment method: If the color paint is sanded, fill it with putty and brush it one or two times. After the varnish is polished, brush it several times to allow the paint to penetrate into the pores and fill it. Latex paint pays attention to the construction method and can be thinly applied once the problem occurs.
Wrinkling in the construction of silicon PU stadium:
Phenomenon: The paint film has regular wrinkles in the form of small wave ripples, sometimes deep and partial or full film thickness. Cause: The coating is too thick at the time of construction, or the ambient temperature is high, the surface of the paint film is quickly dried, but the inside is not dry, and thus wrinkles. When the first layer of paint is not dry, the second layer is applied; if the paint ratio is not appropriate or the dilution is inappropriate, it is easy to produce
Treatment method: Scrape the wrinkle part with a blade, and then smooth it with coarse sand for one or two times according to normal construction. Remember to wait until the first layer of paint is dry before you can apply the second layer, but it should not be too thick.
Cracks in the construction of silicon PU stadium:
Phenomenon: The surface of the paint film has a discontinuous appearance, which causes cracks. In severe cases, cracks can penetrate the coating, causing the paint film to be completely destroyed.
Cause: The construction is too thick, and the thinner is added too little for thick coating. The thicker the coating, the more severe the cracking, which is common in lacquers.
Treatment: Nitrocellulose lacquer can be scrubbed evenly with strong solvent, and then brushed several times.
