Synthetic resin tile with color durable, lightweight, waterproof, tenacity, insulation, corrosion resistance, wind resistance, shock proof, anti hail, anti pollution, advantages of green environmental protection, fire prevention, insulation, convenient installation, beautiful appearance and strong sense of three-dimensional, color very China elements, which is widely used in various types of permanent building roof decoration, especially at home and vigorously promote the "ping changed slope" project.

随着市场的扩大，各种品质的树脂瓦也参差不齐，充满市场。如何选购到高品质又价格合理的树脂瓦、打破内行外行屏障，已成为一种潜在的需求。

With the expansion of the market, all kinds of quality resin tile is uneven, full of market. How to choose high quality and reasonable price resin tiles and break the barrier of professional amateurs has become a potential demand.

目前比较常用的方法有以下几种：

At present, the commonly used methods are as follows:

方法一：称比重。

Method 1: weighing.

树脂瓦含量高的两大成分是PVC和重钙填充物，PVC比重约为1.4；重钙约2.7。 弄下小块树脂瓦，剪裁成规整形状，算出体积，并称重白钢雕塑 小型滚揉机 防火电缆 托辊设备 水刀切割机  铜钟 石雕狮子  校园不锈钢雕塑 扭王块模具，重量÷体积=比重。如果比重≤1.9，可以说明是填充物在合理范围内，适量的填充可以降低成本并起到补强作用，能有效保证产品使用寿命。如果比重>2 证明树脂瓦中添加了大量的重钙及其它填充料，这样一味地增加填充物来降成本，大大地降低了使用寿命，而且产品脆性变大，易折损，只能适用于简易临时性建筑上。如果比重不方便可以用电炉烧灰分，一般树脂如PVC/ASA/PMMA等以及其它助剂色粉用电炉烧10min后灰分可达到≤0.3%，剩下的就是不可燃的重钙填物了，一般控制在50%范围内，通常来说，钙粉的含量越高，其质量越差，成本也越低。

The two major components of resin tile with high content of PVC and calcium carbonate filler, PVC accounted for about 1.4; about 2.7 tsp. Get the next piece of tile, cut into regular shape, calculate the volume, weight, volume and weight = proportion. If the proportion is less than 1.9, that is filling in a reasonable range, the amount of filler can reduce the cost and has a reinforcing effect, can effectively ensure the service life of the product. If the proportion of >2 resin tile adds a large amount of calcium carbonate and other fillers, so simply to increase the filling to reduce the cost and greatly reduces the service life of products, and brittleness, easy damage, is only applicable to simple temporary construction. If the proportion is not convenient and can use the electric stove burning ash, general resin such as PVC/ASA/PMMA and other auxiliary electric furnace burning ash after 10min toner can reach less than 0.3%, the rest is nonflammable, GCC filler, general control in the 50% range, generally speaking, the content of calcium is high, its quality is poor, the cost of the lower.
