镀膜玻璃微珠

镀膜玻璃微珠:

本厂在生产普通玻璃微珠的前题下,还拥有镀膜技术,镀膜玻璃微珠是近年发展起来的玻璃微珠新品种,用于道路标线面撒,显示了优良的特性,受到了广大用户的重视。
玻璃表面涂层、表面不受侵蚀、玻璃微珠在贮存和使用过程中,处于比较潮湿环境中,表面易潮解,造成光的散射,从而影响定向反光特性。
玻璃微珠镀膜材料为一种有机材料,和路用涂料有良好的共溶性,撒于标线表面不易脱落,特别在常温涂料线上使用时(包括水溶涂料)具有很强的粘着力,可长时间保持反光效果。
镀膜玻璃微珠,由于和路用涂料粘附性好,因此通过合理的玻璃颗粒分级,控制面撒后微珠的沉降速率,确保标线始终保持良好的反光效果。
镀膜微珠流动性好,不结块,播撒均匀,容易施工,保证反光效果,实用证明节省用量15%左右。
