塑膠跑道介紹：規(guī)格：厚度：13mm、材質(zhì)：EPDM塑膠顆粒、可選顏色：紅、綠為主要顏色。能解決因地基結(jié)構(gòu)和冷縮熱脹而產(chǎn)生的問題；透水透氣度高；能以EPDM物料設(shè)計(jì)所需圖案及各類標(biāo)志；富彈性，減輕運(yùn)動創(chuàng)傷；恒久耐用，抗寒抗凍是它的特點(diǎn)。塑膠跑道是由聚氨酯橡膠等材料組成的，具有一定的彈性和色彩，具有一定的抗紫外線能力和耐老化力是國際上公認(rèn)的最佳全天候室外運(yùn)動場地坪材料。
塑膠跑道在我國已有30多年歷史,分為全塑型、混合型和顆粒型,主要由面層和基礎(chǔ)層構(gòu)成,厚度一般為13mm。全塑型塑膠跑道的面層由澆注型聚氨酯(RCPU)和防滑膠粒(EPDM或RCPU膠粒)組成,RCPU成本高,因此跑道造價(jià)較高;混合型塑膠跑道使用RCPU作主體材料,加入10%～25%廢舊輪胎膠粒,上部撒防滑膠粒,造價(jià)比全塑型塑膠跑道低;顆粒型塑膠跑道以廢輪胎膠粒為主體材料(60%～70%),用RCPU作粘合劑,采用攤鋪法施工制成,造價(jià)最低,但施工所用的攤鋪機(jī)、噴涂膠粒包膠機(jī)等鋪設(shè)設(shè)備需要進(jìn)口,一次性投入很高,且性能較前兩種差。目前國內(nèi)塑膠跑道以混合型為主。以上各類塑膠跑道均需與瀝青路面基礎(chǔ)良好粘合,基礎(chǔ)造價(jià)一般80～120元·m-2,塑膠跑道總造價(jià)一般230～450元·m-2。雖然塑膠跑道彈性適中,美觀實(shí)用,能提高運(yùn)動員比賽成績和保護(hù)運(yùn)動員免受意外事故傷害,但造價(jià)高,至今未普及應(yīng)用。
Specification: thickness: 13mm, material: EPDM plastic granule, optional color: red, green as the main color.It can solve the problems caused by the foundation structure and shrinkage and heat expansion;High permeability;Design of EPDM materials and all kinds of marks;Rich elasticity to reduce sports injury;Durable and durable, cold and cold resistance is its characteristic.Plastic runway is composed of polyurethane material such as rubber, he certain elasticity and color, he a certain ability to resist ultriolet ray and aging resistance force is internationally recognized as the best all-weather outdoor sports ground floor material.
The plastic runway has a history of more than 30 years in our country. It is divided into plastic, mixed and granular types, consisting mainly of the surface layer and the base layer, and the thickness is generally 13mm.The surface layer of the plastic raceway is composed of pouring polyurethane (RCPU) and anti-skid (EPDM or rccpu). The cost of RCPU is high, so the runway cost is high.The mixed plastic runway USES rccpu as the main material, and 10% ~ 25% of the waste tyre rubber is added, and the upper part of the anti-skid rubber is lower than the plastic runway.Particles type plastic runway by waste tires colloidal particles (60% ~ 70%) as the main material, adhesive for RCPU, the ping bbbbbb construction, lowest cost, but the construction of per, spraying colloidal particles need to import plastic package machine laying equipment, one-time investment is high, and the perbbbbance of the previous two differentia.At present, the domestic plastic runway is mainly mixed.All kinds of plastic racetracks should be bonded with the asphalt pement foundation, the basic cost is generally 80 ~ 120 yuan ·m-2, the total cost of plastic runway is generally 230 ~ 450 yuan ·m-2.Although the plastic runway is flexible and beautiful, it can improve the perbbbbance of athletes and protect athletes from accidental injuries, but it is expensive and has not been widely used.
