树脂瓦是新一代环保化学建筑材料，其以独特的性能优势赢得了越来越多建筑界人士的关注与认可。树脂瓦符合建筑材料未来发展的方向，有着巨大的市场发展前景。

Resin tile is a new generation of environmental protection chemical building materials, which has won more and more attention and recognition of the construction industry with its unique performance advantages. Resin tile is in line with the direction of future development of building materials, and has a huge market development prospects.

目前国内市场涌现出众多的仿制伪劣树脂瓦产品。为了让广大消费者对树脂瓦有一个正确了解与选择，大连凡美化学建材有限公司提供以下四种识别伪劣树脂瓦的方法：

At present, many fake and inferior resin tile products have emerged in the domestic market. In order to enable consumers to have a correct understanding and choice of resin tile, Dalian Fanmei Chemical Building Materials Co., Ltd. provides the following four methods to identify fake and inferior resin tile:

其一：称比重。树脂瓦主要原材料是聚氯乙烯（PVC），其比重约为1.4。

First: weighing. The main raw material of resin tile is polyvinyl chloride (PVC), its proportion is about 1.4.

称重1平方米大的树脂瓦，重量÷体积≈1.4 证明树脂瓦主材为PVC，能有效保证产品使用寿命。重量÷体积＞1.4 证明树脂瓦中添加了大量的重质碳酸钙及其它填充料，这不仅无法保证产品的使用寿命，而且产品脆性很大，易折，只能适用于简易临时性建筑上。

Weighing 1 square metre large resin tile, weight volume 1.4 proves that the main material of resin tile is PVC, which can effectively guarantee the service life of the product. Weight and volume > 1.4 proves that a large amount of heavy calcium carbonate and other fillers are added to the resin tile, which not only can not guarantee the service life of the product, but also has great brittleness and flexibility, and can only be applied to simple temporary buildings.

其二：用火烧。

Second, burn with fire.

用火点燃树脂瓦一角，火源离开后，火苗立刻自息。伪劣树脂瓦火苗有蔓延之势并有较大的刺激气味。原因是：添加大量重质碳酸钙的伪劣树脂瓦为了让产品具有一定的柔韧性，在其中添加了增塑剂，而这种助剂具有助燃作用，这样产品是不符合消防要求而且耐候性能差，在阳光的照射下产生开裂。

A corner of the resin tile is ignited with a fire. When the fire source leaves, the flame immediately ceases to breathe. Fake and inferior resin tile fire has the potential to spread and has a greater stimulating odor. The reason is: in order to make the product flexible, the fake and inferior resin tile with a large amount of heavy calcium carbonate is added plasticizer, which has the function of combustion-supporting, so the product does not meet the fire-fighting requirements and has poor weather resistance, and cracks under the sunlight.

其三：用手掂、敲击。

Thirdly, use your hands to weigh and knock.

树脂瓦质地轻盈，板与板敲击有沉闷感；伪劣仿制树脂瓦用手掂有沉重感。板与板敲击声音清脆。

Resin tiles are light in texture and dull in slab and slab knocking; counterfeit and inferior imitation resin tiles feel heavy in hand. The sound of slab and slab tapping is clear and crisp.

其四：看外观。

Fourth: Look at the appearance.

树脂瓦外形轮廓清晰，材料本身有光泽；反之为伪劣仿制树脂瓦。

The outline of resin tile is clear, and the material itself is glossy; on the contrary, it is fake and inferior imitation resin tile.

针对传统屋面建筑材料存在的诸多难以解决的问题，为达到“十二五”规划中提出的“高强、轻质、节能、节土、利废、环保”的所有功能要求，国内一大批企业开始了屋面复合材料的探索和创新。塑料复合瓦作为一种新型屋面材料正在异军突起。

In order to meet all the functional requirements of "high strength, light weight, energy-saving, soil-saving, waste-profiting and environmental protection" proposed in the 12th Five-Year Plan, a large number of domestic enterprises began to explore and innovate roof composite materials. As a new type of roofing material, plastic composite tile is emerging.
