SPC地板底层:买家需要知道的

SPC地板衬垫可以作为附加衬垫提供,也可以单独安装在地板下面。正确的选择取决于SPC木板结构、底层地板条件、声学要求、安装方法和项目规范。

对于地板进口商、分销商、承包商和商业项目买家,在报价和生产前应确认背衬规格。带有1mm附加背衬的5mm SPC板在结构上不同于没有背衬的6mm SPC板,即使成品厚度相似。

什么是SPC地板底层?

底层是位于SPC地板和底层地板之间的弹性层。根据地板设计,它可以连接到每块木板的背面或以卷的形式单独提供。

经批准的底层系统的主要功能可能包括:

函数
目的
冲击和步行降噪
有助于改善地板系统的声学感觉
缓冲
在刚性木板下方提供受控缓冲
底层分隔
在刚性地板和预制底层地板之间形成一层
安装效率
附加的背衬可以减少处理单独卷的需要
地板系统兼容性
支持整个地板结构的预期性能

底层不能纠正不平整或结构不合适的底层地板。在SPC地板安装之前,必须解决高点、凹陷、潮湿问题和不稳定的表面。

SPC地板用IXPE背衬

IXPE代表辐照交联聚乙烯泡沫。它通常用作硬芯SPC地板的附加背衬。

买家选择IXPE背衬的典型原因包括:

  • 闭孔泡沫结构

  • 厚度和外观一致

  • 吸湿性低

  • 工厂层压到SPC木板

  • 安装方便,无需单独的衬垫辊

但光靠背衬厚度并不能决定性能,买家还应确认背衬密度、粘接质量、地板总厚度以及与锁紧系统的兼容性。

SPC地板EVA背衬

EVA是另一种可以层压在SPC地板背面的泡沫材料。它可以提供缓冲,有不同的密度、厚度和配方可供选择。

在比较EVA支持的SPC地板时,买家应确认:

规格
买家应该确认什么
背衬厚度
成品地板结构中包含的实际厚度
背衬密度
适用于地板和应用的密度
压缩性能
使用过程中抗过度压缩
恢复性能
背衬压缩后的恢复能力
粘接质量
背衬和SPC板之间的粘合一致
锁定兼容性
背衬不应在卡锁接头处产生过度运动

IXPE不应自动被描述为优于EVA,EVA也不应自动被描述为优于IXPE。密度、厚度、生产质量以及与完整地板系统的兼容性比材料名称本身更重要。

附加支持与单独的基础

有两种常见的方法可以为SPC地板提供底层:附加背衬和单独的底层。

附加IXPE背衬

提供不同配方选项的缓冲
确认密度、回收率和粘合质量
独立衬垫
衬垫以卷的形式单独提供
允许独立选择背景
必须获得特定SPC地板系统的批准

附加背衬可以简化安装,因为安装人员不需要处理单独的衬垫辊。当SPC地板为其设计并且项目需要特定的衬垫规格时,单独的衬垫可能是合适的。

可以在SPC地板下安装附加背衬的额外衬垫吗?

额外的衬垫不应该自动添加到已经有附着垫的SPC地板下面。

过于柔软的支撑层可能会允许太多的垂直运动,并增加咔嗒锁接头的应力。在一些地板系统中,这可能会导致连接松动、接头分离或行走过程中的异常运动。

在添加第二层之前,请确认:

  • 地板制造商的安装说明

  • 允许的衬垫厚度和密度

  • 锁定系统要求

  • 底层地板平整度和湿度条件

  • 项目保修要求

如果底层地板不均匀,添加较厚或较软的衬垫不能替代适当的底层地板准备。

应该如何安装单独的衬垫?

当SPC地板系统批准使用单独的衬垫时,底层地板应首先清洁、干燥、稳定且足够平坦。

安装顺序通常包括:


安装检查
1检查底层地板的平整度、湿度、裂缝和不稳定区域
2清洁表面,清除灰尘、碎屑和松散材料
3在准备好的底层地板上铺开批准的衬垫
4修剪衬垫以适合安装区域
5避免不受控制的褶皱、凸起的边缘和不合适的重叠
6根据制造商的说明安装SPC地板

确切的接缝处理和安装方法应遵循衬垫和地板制造商的说明。

SPC地板底层和成品厚度

最常见的规格错误之一是将SPC核心厚度与总成品厚度混淆。

规格示例

大约。成品厚度
示例A
5毫米
1mm IXPE
大约6毫米
示例B
6mm
没有附加的背衬
大约6毫米
示例C
5毫米
1.5mm背衬
大约6.5毫米

对于商业报价和进口订单,SPC芯厚度、背衬厚度和总成品厚度应酌情单独说明。

采购商在订购SPC地板前应该确认什么

对于经销商、批发商、承包商和项目采购商,生产前应确认以下规格:

规格
买家确认
SPC芯厚
确认实际硬芯厚度
总厚度
确认成品厚度,包括附加的背衬
磨损层
确认所需的耐磨层厚度
木板尺寸
确认长度、宽度和公差

背衬厚度
确认实际背衬厚度
背衬密度
根据项目要求确认密度
锁定系统
确认点击锁定配置文件和安装方法
表面设计

SPC商业项目地板底层

对于酒店、公寓、办公室、零售店和其他商业室内,底层选择应与完整的地板规范一起考虑。

项目买家应评估:

  • 预期流量水平

  • 底层施工

  • 声学要求

  • 地板厚度

  • 磨损层厚度

  • 背衬类型和密度

  • 点击锁定系统

  • 安装方法

  • 维护要求

  • 项目预算

没有适合每个SPC地板项目的单一底层规范。正确的解决方案取决于完整的地板系统和项目的条件。

常见问题

所有SPC地板都需要垫层吗?

不可以。一些SPC地板已经包括附加的IXPE或EVA背衬。如果地板制造商允许,没有附加背衬的产品可以使用单独的衬垫。

SPC地板的IXPE比EVA好吗?

不是在所有情况下。合适的选择取决于密度、厚度、恢复、锁定系统兼容性和项目要求。

垫层可以修复不平整的底层地板吗?

不能。衬垫不能纠正明显的高点、凹陷或不稳定的表面。在SPC地板安装前,底层地板应妥善准备。

可以使用两层衬垫吗?

只有在地板制造商特别允许的情况下。过度缓冲可能会产生额外的运动并对SPC锁定接头施加压力。

附加背衬是否包含在SPC核心厚度中?

不一定。SPC核心厚度和附加背衬厚度应单独说明。例如,5mm SPC加上1mm IXPE给出的成品厚度约为6mm。

背衬会影响包装和集装箱数量吗?

是的。附加的背衬会改变产品的总厚度、纸箱结构和重量,这会影响包装和集装箱装载计算。

SPC地板可以直接安装在单独的衬垫上吗?

只有当底层被批准用于特定的SPC地板系统时。地板制造商应在安装前确认兼容性。

进口商在订购SPC地板时应该指定什么?

进口商应确认SPC芯材厚度、总厚度、耐磨层、板材尺寸、背衬类型、背衬厚度和密度、锁定系统、表面设计、包装和订单数量。
