作为组合成模型的基础,材料的好坏直接影响到整个产品的质量。在当今大市场环境下,任何产品都有以次充好的例子,大型飞机模型也不例外。从用料入手,观察大型飞机模型品牌是好是坏?
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?
原因是这种材料是木材等其他材料无法比拟的。优点,,有机玻璃材质颜色多样;当模型显示的各种结构需要用不同的颜色来区分时,颜色的多样性很好地满足了这一要求。
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、好的材料强度高,韧性好;其三,加工方便,有机玻璃适应切割、压型、折弯等多种变形加工工序。
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.
鉴别材料的方法有很多,以下介绍几种:
There are many ways to identify materials, several of which are described below:
质量差的有机玻璃板很脆,在受日光照射后近期没有了原来的光泽,远期会很快退色;
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;
查看如果是质量差的有机玻璃材料稍加烘烤后,两块板材将很难分开,而质量好的板材哪怕是贴在一起了也可以分开的。这就是所谓的粘贴鉴别法;
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;
如果用火烧有机玻璃材料,好的有机玻璃材料不会轻易燃烧有较强的阻燃性,而不好的材料几乎无阻燃的可能,见火就着;
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;
一般好的有机玻璃板材说明和实际是在国家允许公差范围内的,相反劣质的板材则相差很大,表里不一;好的有机玻璃板材透光度很高,表面硬度强,不会轻易出划痕。
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.
