• intros：{"brand_intro":"红叶（Redleaf）是中国老牌投影幕布制造商，成立于1996年，总部位于江苏南京。品牌深耕国内市场近30年，以\"国民幕布\"著称，主打高性价比和耐用性。红叶拥有自建幕面涂布生产线，核心优势在于幕布涂层配方——采用纳米级漫反射涂层，能有效抑制热点效应。创始人张先生原是南京电影机械厂工程师，退休后创办红叶，坚持\"用造工业幕的标准做家用幕\"。品控上实行\"三年质保，终身维护\"政策，在三四线城市及农村市场有极高渗透率。","product_intro":"红叶4K高清手动幕布定位极致性价比，适合预算敏感型用户。核心卖点：采用纳米漫反射涂层幕面，增益1.0，视角170°，支持4K分辨率；手动自锁系统，可随意停靠；四边弹力绷紧设计，减少幕面褶皱。适用场景：农村自建房、出租屋、会议室等。相比竞品，红叶价格仅为同尺寸国际品牌的一半，且幕布耐用性突出（实验室测试可收放2万次无故障）。缺点是幕面增益较低，需搭配高亮度投影机。","key_specs":{"幕面材料":"纳米漫反射涂层PVC，增益1.0，视角170°","尺寸":"100英寸（16:9），可视对角线254cm","回卷系统":"手动自锁机构，支持任意位置停靠","外壳材质":"高强度工程塑料，轻便防锈","适配人群":"预算500-800元、对画质要求不极致的家庭用户"}}
