We know that the acrylic display frame is very sensitive to temperature. In case of high temperature, the acrylic display frame may deform, and some acrylic display frames may be placed outdoors or released to high temperature. How to improve the heat resistance of the acrylic display frame?

　　其实提高亚克力耐热性的方法有很多，每种方法也各有优缺点，有的方法在提高亚克力耐热、保持透明性的同时，会使其它性能下降。为了使亚克力展示架的耐热性和其它性能同时得到改善，有时需要多种改进方法同时并用。

　　In fact, there are many methods to improve the heat resistance of acrylic, and each method has its own advantages and disadvantages. Some methods can improve the heat resistance of acrylic, maintain transparency, and reduce other properties. In order to improve the heat resistance and other properties of acrylic display frame at the same time, it is sometimes necessary to use a variety of improvement methods at the same time.

　　例如共聚，PhMI的主要作用是改善耐热性，MAA的主要作用是提高折光率，这样以PhMI为主单体，MAA为副单体，所得共聚物不仅耐热性提高，且折光率提高，这样所得到的三元共聚物兼具有较高的耐热性和较低的吸湿性，MMA-PhMI-NMA共聚物维卡软化点温度达137℃，吸水率比PMMA低25%左右，其它性能与PMMA相近。

　　For example, the main function of PHMI is to improve the heat resistance, and the main function of MAA is to improve the refractive index. In this way, PHMI is the main monomer, and MAA is the side monomer. The resulting copolymer not only improves the heat resistance, but also the refractive index, so the terpolymer has both high heat resistance and low moisture absorption. The Vicat softening point temperature of mma-phmi-nma copolymer reaches 137 ℃, and the water absorption rate is increased It is about 25% lower than PMMA, and other properties are similar to PMMA.

　　现在还有很多材料学者不断的努力，希望能研制出高性能亚克力展示架，从而扩大它的应用，提高亚克力展示架的经济效益，我们也非常期待，如有需要亚克力展示架的朋友可以与我们联系。

　　Now there are many materials scholars who are constantly striving to develop a high-performance acrylic display frame, so as to expand its application and improve the economic benefits of acrylic display frame. We are also very looking forward to contact us if you need acrylic display frame.
