Schools need to pay attention to the construction plastic runway contaminated runway until now most of our plastic used in plastic, is made of polyurethane industry is diethyl toluene diisocyanate, referred to as the TDI material, made of plastic and then add sticky agents, curing agents, laying on the runway, they built a plastic runway. Whether diethyl toluene diisocyanate or curing agent, adhesive silicon pu badminton courts, golf course are all organic compounds, they are hot and strong light, it will volatilize irritating gases. There are many businesses in order to collect more benefits there are to use this material TDI, especially polyurethane plastic runway, the kinds of plastic runway easy threshing, fade. But the majority of our schools or the use of plastic track. Suggested that schools in the selection of plastic track time, focus on quality, brand and environmental performance plastic runway. The student's safety first. I produced breathable runway general use professional paver, flatness has been effectively controlled, plus upper layer using a professional sprayer with spray polyurethane glue also high, so the surface layer and other types of runway Compared fastness is relatively large, the basic need for maintenance during use, greatly reducing maintenance costs. Elastic layer breathable runway recycled scrap tires and other rubber material crushed into particles paving, reducing the "black pollution", and make a contribution to environmental protection. Basic requirements: breathable plastic runway to the use of cement concrete foundation, foundation requirements should have a certain strength and stability. Can not have, or will have caused cracks and uneven due to freezing frost, in the formation of high water content still need to add cushion acrylic tennis court construction, infrastructure needs to thicken or measures taken to prevent heaving in cold regions according to local geological conditions . The thickness of cement concrete generally require 120-150mm about 3 m straightedge flatness error does not require more than 3 mm, the strength required to achieve more than C20, the slope surface to the outer edge of the inner self plastic runway edge (gutter) put 6 ‰ -10 ‰ slope, it is recommended to do 8 ‰ appropriate. Cement concrete at intervals of not more than 6 meters should be cut sew, sew recommend 4-5 Mitch, cement concrete curing period as proposed by the standard curing period of 28 days. In the case of poor flatness is prohibited to do with pure cement mortar leveling layer of skin type, should be left to deal with when the surface construction. Construction Technology: Brush evenly with a brush to single-component glue or cement foundation primer. Before primer uncured, the single-component glue and black rubber granules according to a predetermined ratio ratio, stir with a mixer, transported to the paving site, as required by the paver paving thickness; after curing, it becomes elastic layers. Breathable surface with spray glue and EPDM rubber, EPDM powder ratio according to a predetermined ratio, stir, pour a dedicated sprayer, clockwise and counterclockwise points twice to three times spraying, curing and for slip resistant layer of color is now widely used for the red and green.
