作為組合成模型的基礎，材料的好壞直接影響到整個產品的質量。在當今大市場環(huán)境下，任何產品都有以次充好的例子，大型飛機模型也不例外。從用料入手，觀察大型飛機模型品牌是好是壞？
As the basis of the combination model, the quality of the material directly affects the quality of the whole product. In today's large market environment, any product has a shoddy example, model is no exception. Start with the material, observe the model brand is good or bad?
原因是這種材料是木材等其他材料無法比擬的。優(yōu)點，，有機玻璃材質顏色多樣；當模型顯示的各種結構需要用不同的顏色來區(qū)分時，顏色的多樣性很好地滿足了這一要求。
The reason is that this material is incomparable to other materials like wood. Advantages: first of all, plexiglass material has various colors; When the various structures displayed in the model need to be distinguished by different colors, the variety of colors well meets this requirement.
其二、好的材料強度高，韌性好；其三，加工方便，有機玻璃適應切割、壓型、折彎等多種變形加工工序。
Second, good materials have high strength and good toughness; Third, the processing is convenient, plexiglass adapt to cutting, pressing, bending and other deformation processing procedures.
鑒別材料的方法有很多，以下介紹幾種：
There are many ways to identify materials, several of which are described below:
質量差的有機玻璃板很脆，在受日光照射后近期沒有了原來的光澤，遠期會很快退色；
Poor quality of the plexiglass plate is very brittle, in the near future after sunlight without the original luster, the long-term will soon fade;
查看如果是質量差的有機玻璃材料稍加烘烤后，兩塊板材將很難分開，而質量好的板材哪怕是貼在一起了也可以分開的。這就是所謂的粘貼鑒別法；
Check if it is a poor quality plexiglass material after a little baking, the two plates will be difficult to separate, and the quality of the plate even if it is stuck together can also be separated. This is called paste discrimination;
如果用火燒有機玻璃材料，好的有機玻璃材料不會輕易燃燒有較強的阻燃性，而不好的材料幾乎無阻燃的可能，見火就著；
If you use fire plexiglass materials, good plexiglass materials will not easily burn has strong flame retardant, and bad materials almost no flame retardant possible, see the fire;
一般好的有機玻璃板材說明和實際是在國家允許公差范圍內的，相反劣質的板材則相差很大，表里不一；好的有機玻璃板材透光度很高，表面硬度強，不會輕易出劃痕。
General good plexiglass plate description and the actual is in the country to allow the tolerance range, on the contrary, inferior plate is very different, duplicity; Good plexiglass plate transmittance is very high, surface hardness is strong, won't give scratch easily.
