幕布特点 MG系列高清白塑是应用最广泛的前投幕布材料之一。由三层结构组成，表面为改良性白色PVC投影面，中间层是玻璃纤维，底层为黑色PVC。在白色PVC层的表面，由凹凸不平分布均匀的特殊形状组成，从而形成良好的漫反射效果，使画面的亮度更均匀，视场角更大。玻璃纤维由于具有良好的物理性能（5%收缩率）及耐候性，使得玻纤能够长期保持其平整性及不卷边的物理特性，从而保证整个投影面的平整性。底层黑色PVC具有阻光、不透光特性，保证投影的光线不会穿透幕布形成杂散光，从而影响观看效果。在色彩还原效果与对比度的表现方面，拥有良好的统一性。具有色彩还原性好、成像清晰、视场角大、光线柔和、耐候性良好等特点。 适用投影机：长焦投影机 （投射比＞1.2：1） 适用环境：暗光（50Lx）环境下 适用场所：商务会议、教学、演讲演示等 Fabric Specs MG is the wide used screen fabric on the market, which is composed of three layers material.
