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，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.

方法二：用火烧。

Method two: use 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。

Ignite the corner of the resin tile with fire. When the fire source leaves, the flame immediately starts. The inferior resin tile flame has the tendency to spread, and has the bigger stimulation smell. The reason is: fake resin tile add a lot of heavy calcium carbonate in order to make the product has certain flexibility, in which to add a plasticizer, and this additive has the combustion effect, this product is not in accordance with the requirements of fire and weather resistance, have cracked in the sunlight.

方法三：用手掂、敲击。

Methods: using his hands, hitting three.

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 tile light texture, the board and the board have struck boredom; shoddy imitation resin tile with weigh a heavy hand. Plate and board knock sound crisp.

方法四：查看供方有无检测报告

Method four: check whether the supplier has test report

合成树脂瓦国标规格通常为0.88M和0.96M，厚度为3MM，每平米重量为6KG，标准的合成树脂瓦在其选购时会出示其国家化学建筑材料测试中心的相关检测报告（没有国家化学建材检测中心的检测报告是不允许其在市场上销售的）：

Synthetic resin tile GB specifications are usually for 0.88M and 0.96M, the thickness of 3MM, weight per square meter is 6KG, the standard of synthetic resin tile in the detection report related purchase will show the National Chemical Building Material Test Center (inspection report no national chemical building materials testing center is not allowed to sell in the market):

1.人工老化检测报告（人工老化10000小时相当于实际使用20年以上）

1. artificial aging test report (artificial aging 10000 hours, equivalent to the actual use of more than 20 years)

2.低温落锤冲击（0℃）检测报告(一公斤重的钢球自1米的高度自由落在瓦面上不产生裂纹，低温下落球冲击10次产品无破坏。经过10个冻融循环，产品无空鼓，起泡，剥离，裂纹等现象。) 标准的合成树脂瓦自身具有非常好的抗荷载性能，经国家建筑材料及构件质量监督站检测，在支撑间隔750MM，均布加载150KG情况下，无任何破坏。劣制的合成树脂瓦工人施工踩在瓦上作业时会产生破碎。

2. low temperature drop hammer impact (0) test report (a kilogram of steel ball from 1 meters high free fall on the tile surface does not produce cracks, low temperature drop ball impact 10 times, no damage to the product. After 10 freeze-thaw cycles, no hollowing, blistering, peeling, cracks and other phenomena. The standard synthetic resin tile itself has very good resistance to load performance, by the national building materials and component quality supervision station detection, in the support interval 750MM, uniformly loaded 150KG case, without any damage. Bad synthetic resin tile workers will break when they work on tiles.

3.防火建材检测报告（建筑内部装修设计防火规范A2.6塑料燃烧性能判定B1级以上）

3. fire protection building materials inspection report (building interior decoration design fire code A2.6 plastic burning performance determination B1 class above)

4．耐化学试剂检测 标准的合成树脂瓦可以长期抵御酸，碱，盐等多种化学物质腐蚀，实验浸泡盐，碱及60%以下各种酸中24小时无化学作用。劣制的合成树脂瓦面层采用其颜料会产生化学反应，甚至产生褪色。

4. synthetic resin tile that can resist chemical reagent test can resist acid, alkali, salt and other chemical substances for a long time. Immersion in salt, alkali and 60% or less acid has no chemical effect for 24 hours. The bad synthetic resin tile surface uses its pigment to produce chemical reaction and even fade.

最后，就要看共挤层了，改性PVC作为共挤层，耐候性是硬伤，已经不被推广采用了，PMMA作为共挤层，耐候性的问题是解决了，但是PMMA（俗名：有机玻璃、亚克力）主要是用来做高光滑镜面质感的，抗冲击差，硬物撞击如雨滴冰雹等会容易产生微裂纹毛刺，另外加工过程中也容易拉毛，作为瓦用共挤材料是放错了地方，ASA彩色共挤料作为共挤层，完美的解决了这些问题，ASA替换了ABS容易断裂的不饱和双键，提升了耐候性，又保留了ABS优异的机械性能，实践已经证明它是最理想的树脂瓦表层共挤材料。

Finally, to see the coextrusion layer, modified PVC as extruded layer, weatherability is flawed, has not been widely used, PMMA as extruded layer, weather resistance problem is solved, but the PMMA (common name: organic glass, acrylic) is mainly used for high smooth surface texture, poor impact resistance bump, such as rain hail will be easy to produce micro cracks and burrs, process is also easy to scratch, as the tiles for the co extruded material is put in the wrong place, ASA color coextrusion material as co extruded layer, the perfect solution to these problems, ASA replaced ABS easy to fracture unsaturated double bonds, enhance the weathering ABS, and retained the excellent mechanical properties, practice has proved that it is resin tile surface coextrusion material is the most ideal.
