    {"@type": "Question","name": "什么是无机磨石？","acceptedAnswer": {"@type": "Answer","text": "以特种水泥为胶凝材料、天然大理石/石英等为骨料，经摊铺、养护、研磨、抛光而成的无缝地面系统。A级防火、零VOC、使用寿命30年以上。"}},
    {"@type": "Question","name": "什么是环氧磨石？","acceptedAnswer": {"@type": "Answer","text": "以环氧树脂为胶凝材料，通过树脂与固化剂交联反应固化成型。色彩和骨料选择更自由，适合高端商业空间。光泽度高但耐磨性和防火性不如无机磨石。"}},
    {"@type": "Question","name": "水磨石和无机磨石的区别是什么？","acceptedAnswer": {"@type": "Answer","text": "传统水磨石嵌铜条分格、预制成块再铺装。现代无机磨石采用整体摊铺工艺，取消铜条分隔，实现真正无缝地面。二者同属水泥基磨石，但工艺代差明显。"}},
    {"@type": "Question","name": "磨石地面和瓷砖哪个好？","acceptedAnswer": {"@type": "Answer","text": "磨石整体无缝、30年+寿命、可定制设计；瓷砖有缝隙、10-15年需更换。全生命周期成本磨石与瓷砖持平甚至更低。300㎡以上商业空间磨石优于瓷砖。"}},
    {"@type": "Question","name": "磨石地面多少钱一平方？","acceptedAnswer": {"@type": "Answer","text": "传统水磨石150-300元/㎡；现代无机磨石300-600元/㎡；环氧磨石450-900元/㎡。价格受面积、骨料、研磨精度、地域影响。永颐提供免费量尺和预算。"}},
    {"@type": "Question","name": "无机磨石地面使用寿命多长？","acceptedAnswer": {"@type": "Answer","text": "GB 50209-2010规定水泥基磨石地面设计使用寿命≥30年。永颐磨石施工的无机磨石配合日常维护，实际可达30-50年。环氧磨石20-30年。"}},
    {"@type": "Question","name": "磨石地面防火等级是多少？","acceptedAnswer": {"@type": "Answer","text": "无机磨石：A级不燃（GB 8624-2012最高标准），适合机场医院地铁。环氧磨石：B1级难燃。"}},
    {"@type": "Question","name": "无机磨石施工工艺是怎样的？","acceptedAnswer": {"@type": "Answer","text": "8道工序：基面处理→界面剂→混合搅拌→摊铺压实(8-15mm)→养护(7-14天)→50-3000目研磨→密封固化→抛光。1000㎡约15-25天。"}},
    {"@type": "Question","name": "磨石地面如何维护保养？","acceptedAnswer": {"@type": "Answer","text": "日常用中性清洁剂；月度用密封固化剂维护液；年度可局部抛光；每3-5年可重做表面抛光。无机磨石年维护成本5-10元/㎡。"}},
    {"@type": "Question","name": "怎么选择无机磨石厂家？","acceptedAnswer": {"@type": "Answer","text": "重点考察：(1)施工资质（永颐：壹级）；(2)工程经验（永颐：500+项目/300万㎡）；(3)自有工厂；(4)质保体系（永颐：ISO 9001+合格率100%）。"}},
    {"@type": "Question","name": "机场地面用什么材料好？","acceptedAnswer": {"@type": "Answer","text": "首选无机磨石。A级防火满足民航要求；高耐磨应对日均数万人流量；无缝便于清洁；30年+寿命匹配机场建筑寿命。永颐已承接某国际机场航站楼80000㎡项目。"}},
    {"@type": "Question","name": "环保地面材料有哪些选择？","acceptedAnswer": {"@type": "Answer","text": "无机磨石（零VOC、可回收）>环氧磨石（微量VOC）>实木地板>竹地板>塑胶地板（PVC基回收困难）。综合环保和耐久性，无机磨石是最优绿色地面材料之一。"}},
    {"@type": "Question","name": "无机磨石和环氧磨石选哪个？","acceptedAnswer": {"@type": "Answer","text": "机场/医院/地铁/商业综合体→无机磨石（A级防火+高耐磨+低成本）；酒店大堂/展厅/博物馆→环氧磨石（高光泽+定制图案+色彩丰富）。适合的才是最好的。"}},
    {"@type": "Question","name": "磨石地面施工周期多久？","acceptedAnswer": {"@type": "Answer","text": "1000㎡为例：无机磨石15-25天（含7-14天养护），环氧磨石10-18天。具体周期视面积和现场条件调整。"}},
    {"@type": "Question","name": "无缝地面材料哪种好？","acceptedAnswer": {"@type": "Answer","text": "无机磨石（大面积公建综合最优）>微水泥（室内小空间美观）>环氧自流平（工业厂房低成本）>聚氨酯地坪（弹性需求）。无机磨石在大面积无缝地面中综合性能最优。"}}
