Composition and structure of resin tile

合成樹(shù)脂瓦的主要成分是合成樹(shù)脂，即有人工合成的一類高分子聚合物。在外力作用下可呈塑性流動(dòng)狀態(tài)，某些性質(zhì)與天然樹(shù)脂相似。

The main component of synthetic resin tile is synthetic resin, which is a kind of synthetic polymer. Under the action of external force, it can flow in a plastic state, and some properties are similar to those of natural resin.

合成樹(shù)脂瓦的面層材料為關(guān)鍵，面層材料的選用直接影響 樹(shù)脂瓦的使用壽命，大多數(shù)情況下選用的超耐候材料ASA或者PMMA,通過(guò)表面共擠成型。產(chǎn)品的耐候性直接導(dǎo)致了合成樹(shù)脂瓦的使用壽命。

The surface material of synthetic resin tile is the most important one. The selection of the surface material directly affects the service life of the resin tile. In most cases, the excellent super weather resistant material ASA or PMMA is selected and finally formed by surface coextrusion. The weatherability of the product directly leads to the service life of the synthetic resin tile.

于此同時(shí)，合成樹(shù)脂瓦的好壞，還與表面材料的使用量，和共擠技術(shù)有關(guān)系。

At the same time, the quality of synthetic resin tile is related to the usage of surface materials and coextrusion technology.

標(biāo)準(zhǔn)的合成樹(shù)脂瓦可以長(zhǎng)期抵御酸，堿，鹽等各種化學(xué)物質(zhì)腐蝕，實(shí)驗(yàn)浸泡鹽，堿及60%以下各種酸中無(wú)化學(xué)作用。劣制的合成樹(shù)脂瓦面層采用其顏料會(huì)產(chǎn)生化學(xué)反應(yīng)，甚至產(chǎn)生褪色。

The standard synthetic resin tile can resist the corrosion of acid, alkali, salt and other chemicals for a long time. There is no chemical effect in the experiment soaking salt, alkali and various acids below 60% for 24 hours. The bad synthetic resin tile surface layer will produce chemical reaction and even fade when using its pigment.
