产品详细信息

聚甲基丙烯酸甲酯挤出成型

聚甲基丙烯酸甲酯可通过浇铸、注射、挤出、热成型等工艺成型

注射成型，其中注射成型使用悬浮聚合制成的颗粒，这些颗粒在普通柱塞式或螺杆式注射成型机中成型。注塑制品也需要进行后处理，以消除内部应力。应力处理在70-80°C热风循环干燥箱中进行，处理时间取决于制品的厚度

一般需要4小时左右

挤出成型，聚甲基丙烯酸甲酯也可以通过悬浮聚合进行挤出成型

生产的颗粒可用于有机玻璃板、杆、管、片等，但由于聚合物的低分子量、机械性能、耐热性、，耐溶剂性

耐溶剂性不如铸造型材。其优点是生产效率高，尤其是管道

铸造材料和其他材料时会铸模。难以制造型材。挤出成型可采用单级或

两级通风挤出机，螺杆长径比一般为20-25

Product Details

pmma extrusion molding

Polymethyl methacrylate can be cast, injection, extrusion, thermoforming and other processes.

Injection molding, in which injection molding uses pellets made by suspension polymerization, which are molded in

Ordinary plunger type or screw type injection molding machine. Injection molded products also need post-processing to eliminate internal

The stress treatment is carried out in a 70-80°C hot air circulation drying oven, and the treatment time depends on the thickness of the product.

Generally, it takes about 4h.

Extrusion molding, polymethyl methacrylate can also be extrusion molding, using suspension polymerization

The produced pellets are prepared for plexiglass plates, rods, pipes, sheets, etc., but prepared in this way

The profile, especially the plate, due to the low molecular weight of the polymer, mechanical properties, heat resistance, resistance

The solvent resistance is not as good as that of cast-molded profiles. Its advantage is high production efficiency, especially for pipes.

Molds when casting materials and other materials. Difficult to manufacture profiles. Extrusion molding can adopt single-stage or

For two-stage vented extruders, the ratio of screw length to diameter is generally 20-25.
