如何选购合成树脂瓦
如何选购合成树脂瓦
How to choose synthetic resin tile
其一:称比重。树脂瓦主要原材合成树脂瓦料是聚氯乙烯(PVC)，其比重约为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合成树脂瓦酸钙及其它填充料，这不仅无法保证产品的使用寿命，而且产品脆性很大，易合成树脂瓦折，只能适用于简易临时性建筑上。(由于体积测量不是很方便，通常我们选用专业的马弗炉，做灰分燃烧试验。由于树脂燃烧后不会留下灰分，所以灰分的主要为不可燃的重钙，这样我们就可以得出其钙粉的含量，通常来说，钙粉的含量越高，其质量越差，成本也越低。)
One is called specific gravity. The main raw material of resin tile is PVC, its specific gravity is about 1.4. Weighing 1 square meter 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. The weight ÷ volume > 1.4 proves that a large amount of heavy carbon synthetic resin calcium titanate and other fillers are added to the resin tile, which not only can not guarantee the service life of the product, but also the product is brittle and easy to be broken, so it can only be applied to simple temporary buildings. (as the volume measurement is not very convenient, we usually choose a professional muffle furnace for ash combustion test. Since the resin will not leave ash after combustion, the main ash is non combustible heavy calcium, so we can get the content of calcium powder. Generally speaking, the higher the content of calcium powder, the worse its quality and the lower its cost. )
其二:用火烧。 用火点燃树脂瓦一角，火源离开后，火苗合成树脂瓦立刻自息。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合成树脂瓦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，这样产合成树脂瓦品是不符合消防要求而且耐候性能差，在阳光的合成树脂瓦照射下产生开裂。(合成树脂瓦，表层使用进口的树脂ASA，因为ASA为不可燃树脂而且非常昂贵。所以，如果针对表面点火，瓦会燃烧，这恰恰说明其使用的为优质树脂，具有很高的保色、抗老化性能。)
Second: burn with fire. Ignite a corner of the resin tile with a fire. When the fire source leaves, the synthetic resin tile of the fire immediately stops. The fake resin tile fire has the potential of spreading and has a strong smell of stimulation. The reason is: in order to make the synthetic resin tile have certain flexibility, a plasticizer is added to the fake and inferior resin tile with a large amount of heavy calcium carbonate, and this auxiliary has the combustion supporting effect, so the synthetic resin tile is not in line with the fire protection requirements and has poor weather resistance, resulting in cracking under the irradiation of the sunlight synthetic resin tile. (for synthetic resin tile, imported resin ASA is used as the surface layer, because ASA is non combustible resin and very expensive. Therefore, if the ignition is carried out on the surface, the tile will burn, which means that it uses high quality resin and has high color retention and anti-aging properties. )
