Abstract

本发明涉及一种用于涂装卫浴部件(1)的方法，该方法至少包括以下步骤：a)提供卫浴部件(1)，其中，该卫浴部件(1)具有至少一个液体通道(2)；以及b)对至少一个液体通道(2)的内表面(3)至少部分地涂装涂层(4)，其中，该涂层(4)具有包含铜的至少一层(5)。

Description

用于涂装卫浴部件的方法
技术领域
本发明涉及一种用于涂装卫浴部件的方法。该卫浴部件例如可以是用于卫浴设备配件的配件壳体，所述卫浴设备配件用于例如在洗手池、厨房水槽、淋浴器和/或浴缸处按需提供液体。
背景技术
卫浴部件可以具有液体通道，液体例如水可以经由液体通道被输送到卫浴部件或卫浴设备配件的流出部。液体与卫浴部件的材料接触，使得材料的成分，尤其是材料的合金成分，例如铅，可能被包含在液体中。但由于这些成分可能对健康有害，因而这是不期望的。
发明内容
因此本发明的目的是，至少部分地解决根据现有技术所描述的问题，尤其给出一种用于涂装卫浴部件的方法，利用该方法可以至少减少卫浴部件的材料成分释放到液体中。
该目的通过根据独立权利要求的特征的方法实现。在从属权利要求中给出本发明的其他有利的实施方案。应指出，在从属权利要求中单独列出的特征可以以任何技术上有意义的方式相互组合，并定义本发明的其他实施方案。此外，在说明书中进一步详述和阐释在权利要求中给出的特征，并示出本发明的其他优选实施方案。
为此使用一种用于涂装卫浴部件的方法，该方法至少包括以下步骤：a)提供卫浴部件，其中，该卫浴部件具有至少一个液体通道；以及b)对所述至少一个液体通道的内表面至少部分地涂装涂层，该涂层具有包含铜的至少一层。
卫浴部件例如可以是用于卫浴设备配件的配件壳体。这种卫浴设备配件尤其用于为洗手池、厨房水槽、淋浴器和/或浴缸按需提供液体，尤其是水。此外，卫浴设备配件尤其用于获取或输出液体。
卫浴部件可以至少部分地由金属构成和/或以铸件方式设计。卫浴部件或卫浴部件的材料可以包含例如作为合金元素的铅。卫浴部件可以至少部分地由塑料构成和/或以塑料注塑件的方式设计。
卫浴设备配件可以包括用于调节水温和/或取水量的至少一个调节元件。
此外，卫浴设备配件可以在使用者的可见区域中使用，从而卫浴部件可以以明装构件的方式设计。备选地，卫浴部件也可以设计为暗装构件。这种暗装构件例如可以内置到建筑物墙壁中，从而通常对用户不可见(在装入状态下)。
卫浴部件具有至少一个用于液体的液体通道。液体通道尤其可以被设计成穿过卫浴部件和/或被设计在卫浴部件中。此外，至少一个液体通道尤其不是卫浴部件的单独构件。而是至少一个液体通道可以与卫浴部件设计成一体的。至少一个液体通道可以设计为卫浴部件中的空腔。此外，至少一个液体通道可以至少部分以孔的方式设计。此外，至少一个液体通道例如可以至少部分地延伸穿过卫浴部件或配件壳体的流出部。此外，至少一个液体通道例如可以从用于卫浴部件的至少一个功能部件的接纳空间延伸到流出口。此外，至少一个液体通道可以至少部分地由卫浴部件或由卫浴部件的材料界定。经由液体通道，液体能够例如被输送至卫浴部件或卫浴设备配件的流出口。在这种情况下，液体尤其会接触卫浴部件的材料。
在步骤a)中提供卫浴部件。这可以包括制造卫浴部件(未涂装或作为半成品)。步骤a)可以包括将卫浴部件在环境中的定向和/或定位，随后可以在环境中(立即)执行步骤b)。
之后或紧接着，在步骤b)中为至少一个液体通道的内表面至少部分地施加涂层。至少一个液体通道的内表面被至少部分地或全部地涂装涂层。卫浴部件的外表面也可以在该步骤中至少部分地涂装有涂层。对至少一个液体通道的内表面的至少部分涂装可以与对卫浴部件的外表面的至少部分涂装同时进行。对至少一个液体通道的内表面的涂装可以被限定到该至少一个液体通道在卫浴部件的外表面上的交汇区域。该区域可以例如从卫浴部件的外表面沿该至少一个液体通道具有最长10cm(厘米)、优选最长5cm的长度。
(在步骤b中产生的)涂层具有包含铜的至少一层。因此，涂层可以由单层铜构成，其尤其直接涂覆到至少一个液体通道的内表面上。涂层可以包括多层。在这种情况下，涂层可以是多层系统，其尤其可以用于产生装饰性和/或功能性表面。为此，各个层尤其是依次形成和/或在其材料组分方面有所不同。由铜构成的层和/或各个层优选各自具有1μm(微米)至60μm、优选4μm至40μm的层厚度。
为此，卫浴部件尤其可以至少部分地浸入到电解液中。由铜构成的层和/或涂层的各个层可以电解沉积在至少一个液体通道的内表面和/或卫浴部件的外表面上。
在涂层区域中可以防止液体接触卫浴部件的材料，使得卫浴部件材料中对健康有害的成分不会被包含在液体中。
卫浴部件可以由铜或铜合金构成。铜合金可以例如包括锌。此外，铜合金可以是黄铜或青铜。
该涂层可以包括由铜构成的第一层。铜的第一层尤其直接形成在至少一个液体通道的内表面和/或卫浴部件的外表面上。
该涂层可以包括由镍磷合金构成的第二层。第二层尤其可以直接形成在第一层上。镍磷合金中磷的质量分数尤其可以至少为8％。镍磷合金中磷的质量分数优选为8％至14％，尤其优选为10％至12％。由镍磷合金构成的第二层尤其电解沉积在卫浴部件上。镍磷合金尤其具有防腐蚀功能。因此，镍磷合金在很大程度上防止了卫浴部件的腐蚀并因此改善了腐蚀性能，尤其是具有功能特性的装饰涂层的腐蚀性能。因此，明显减少了由于损坏、未完全封闭的或多孔的涂层而导致的卫浴部件腐蚀，从而避免了构件故障和/或外观缺陷。涂层尤其(视情况除了镍磷合金层外)不具有其他包含镍的层。
该涂层可以包括由铬构成的第三层。该第三层尤其直接形成在第二层上。
第三层的铬可以由六价或三价铬电解液沉积产生。
该涂层可以包括由锆化合物、铬化合物或钛化合物构成的第四层。这些化合物的混合也可以在第五层中实现。第五层尤其直接涂覆到第四层上。该涂层的目的尤其是实现特定的颜色。例如利用该涂层在电镀铬层上实现红色调、金色调或不锈钢外观。这些层的组成决定了所获得的颜色。这些层主要由不同比例的氮化锆(ZrN)、氮化钛(TiN)和/或氮化铬(CrN)组成。
第四层可以通过物理气相沉积(PVD法)产生。
第四层可以由无定形碳层产生。无定形碳层尤其是类金刚石碳层(DLC＝“diamond-like carbon”)。
可以在涂层中加工出拉丝结构/刷状结构。拉丝结构的施加通常与已经提到的PVD涂层一起进行。最终的端面例如是“拉丝不锈钢”或“拉丝镍”。拉丝是通过将物体压在旋转的轮盘上来进行的。例如，这些轮盘可以是带有相应的抛光膏、纤维刷或剑麻刷的抛光圈。该加工步骤在PVD涂层之前或甚至在镀铬之前进行。
根据另一方面，还提出了一种卫浴部件，该卫浴部件使用此处公开的方法制造和/或具有此处公开的至少一个液体通道的内表面的涂层的层结构。
