彩砂环氧地坪的原材料选择是非常有讲究的，彩砂是选用颗粒状的彩色石英砂，这不仅赋予地坪的优美装饰性能，而且保障了地坪的高抗压性和高耐磨性。树脂是采用无溶剂的透明环氧树脂，不掺杂粉状填料或颜料，保障环氧树脂优异的化学和物理性能。

The raw material selection of coloured sand epoxy floor is very particular. The coloured sand is the coloured quartz sand with granular shape. It not only gives the floor beautiful decorative performance, but also ensures the high compressive resistance and high wear resistance of the floor. The resin is a solvent-free transparent epoxy resin, not doped with powder fillers or pigments, to protect the excellent chemical and physical properties of epoxy resin.

彩砂环氧地坪中的彩砂是指彩色石英砂，而非其它类型砂。之所以选用石英砂，是因为石英原料来源广、矿物硬度高，这就使地坪的原材料和质量有了根本的保障。石英砂是无色或白色的，通过新技术染色工艺，可以把石英砂颗粒加工成颜色丰富的彩色砂粒，配合以彩砂混合装饰设计，赋予地坪多姿的色彩美感。石英砂还应是圆型或球形颗粒状的，便于在施工过程中颗粒间自由滑动，从而使砂粒能够尽量“最紧密堆积”，使环氧彩砂层充分密实，保证地坪优异的抗重压性和耐磨性。此外，环氧彩砂层充分密实后，可以节省面层的树脂用量，降低成本。

Colored sand in epoxy floor is colored quartz sand instead of other types of sand. The reason why quartz sand is selected is that quartz has a wide source of raw materials and high mineral hardness, which makes the raw materials and quality of the floor have a fundamental guarantee. Quartz sand is colorless or white, through the new technology of dyeing, quartz sand particles can be processed into colorful sand grains, with mixed decorative design of colored sand, giving the floor a colorful aesthetic feeling. Quartz sand should also be round or spherical granular, easy to slide between the particles during construction, so that the sand can be as close as possible to "pile up", so that the epoxy colored sand layer is fully compact, to ensure that the floor excellent resistance to compression and wear resistance. In addition, the epoxy resin sand layer is sufficiently dense, which can save the resin consumption of the surface layer and reduce the cost.

选择好的彩色石英砂对彩砂环氧地坪的高质量至关重要，过去高质量彩砂主要靠进口，一些外资企业直接从国外购得。但是，现在国内已有厂家能生产高品质彩色石英砂，所生产的彩砂，其色泽、颗粒圆度、粒度配比及耐化学性等指标均与国外产品相当，质量稳定可靠，不仅价格较低，而且供货周期短、售后服务好，已为外资公司所采用或为指定用砂。

Choosing a good color quartz sand is very important to the high quality of color sand epoxy floor. In the past, high quality color sand was mainly imported, and some foreign-funded enterprises purchased it directly from abroad. However, some domestic manufacturers can produce high quality color quartz sand. The color, roundness, particle size ratio and chemical resistance of the colored sand are comparable to those of foreign products. The quality of the colored sand is stable and reliable.
