丙烯酸和有机玻璃之间的区别

作者:奥凯高分子  发布时间:2019-09-23 15:25  点击量:


雷电竞app下载经常被问到这样一个问题:有机玻璃和丙烯酸有什么区别?雷电竞app下载可以给出一个简短的答案:没有绝对的区别,这是因为丙烯酸是聚甲基丙烯酸甲酯的通常缩写,随着时间的推移,这个品牌名称已成为“有机玻璃”的通用名称。
 
有机玻璃 - 差不多一个世纪
聚甲基丙烯酸甲酯/丙烯酸酯的生产始于20世纪30年代,并于1936年由美国某公司首次上市。基本材料是硫酸,氰化氢,甲醇和丙酮。这些都不是最安全的物质,但最终雷电竞app下载是完全无害的。有机玻璃是易燃的,但如果它燃烧,它根本不会形成任何有害物质。残留产物是二氧化碳和水。
 
有机玻璃不耐热,因此不能用于安全应用。由于其重量,强度和相对低的价格,这种塑料通常用于大型表面的上釉,例如风和噪音屏。由于其强度,有机玻璃广泛用于动物园的大型水族馆和游泳池。这要求玻璃厚度达到30厘米,如果使用普通玻璃,透明度太低,而且玻璃窗太厚。
 
两种类型的丙烯酸:铸造和挤压
有两种类型的有机玻璃:铸造和挤出型。铸造版本在生产过程后模制成平板。浇注后,挤出的类型被卷成更薄的厚度。当厚度减小时,片材表面增加,使得更容易制造更大的丙烯酸片材。缺点是片材中的应力增加,在加工过程中挤出的片材容易破裂和破裂。所谓的“预算有机玻璃”也不总是抗紫外线,重要的是要知道这种材料是否用作玻璃。
