The Hardness of the Acrylic Sheet

Many substances have their hardness values, so what is the surface hardness value of acrylic board? What's the hardness of it? Generally speaking, it is expressed with H value, generally refers to its surface resistance to scratch, the surface of the ordinary acrylic plate can only reach about HB~1H, through the surface hardening of the acrylic plate can be promoted to 4H~6H. The higher the H value, the higher the surface hardness of the object. If we commonly use the Chinese pencil, it will be labeled with 4B and 5B according to the hardness of the pen core.

Plastic Artist-Acrylic Processing Technology

Acrylic can be used casting, injection molding, extrusion, thermoforming, laser engraving, laser cutting and other processes. Casting molding Casting molding for forming plexiglass sheet, bar and other profiles, that is, body-bulk polymerization method of forming profiles. After casting molded products need to be post-processed, post-processing conditions are incubated at 60 ℃ 2 hours, 120 ℃ for 2 hours. Injection molding Injection molding using suspension polymerization obtained pellets, molding in the ordinary plunger or screw injection molding machine. Process parameters include screw injection molding machine, plunger injection molding machine, barrel temperature, injection molding products also need to eliminate the internal stress treatment, processing in the hot air circulation oven at 70 ~ 80 ℃, processing time as the thickness of acrylic products, the general All about 4 hours. Thermoforming Thermoforming is the process of making plexiglass sheets or she...

The Classification Of Acrylic Sheet

  Acrylic Sheet   is available in a wide variety of colors and have excellent overall properties, providing designers with a wide range of options. Acrylic sheets can be dyed and painted on the surface, screen printing or vacuum coating. In general, it is divided into the following two categories. Acrylic cast sheet: high molecular weight, excellent stiffness, strength and excellent chemical resistance. This  Diffuser Acrylic Sheet  is characterized by small batch processing, unmatched flexibility in color system and surface texture effects, and a full range of specifications for a variety of special applications. Acrylic extruded sheet: Compared to the cast sheet, the extruded sheet has a lower molecular weight and a slightly weaker mechanical properties. However, this feature facilitates bending and thermoforming processes and facilitates rapid vacuum forming when handling larger sheets. At the same time, the thickness tolerance of the  Extruded Sheet  is...

What are the Basic Points that PC Diffuser Sheet needs to Master During the Construction Process?

In recent years, we can see that  PC Diffuser Sheet  has become a popular sheet, and it has also been favored by business users and enterprise groups in many fields. So, in the daily construction process of these plates, what aspects need to pay more attention to ensure the integrity of the project? Let's take a look at the basic essentials of PC diffuser in the construction process. As a  China Acrylic Sheet Manufacturer , share with you. The basic essentials of PC diffuser construction First of all, before the construction of the PC diffuser board, the staff must conduct a corresponding inspection of the surrounding environment, so as to determine the stacking of the board and the place where the related equipment is placed. To know that the construction preparation work can be said to implement the entire PC diffuser construction project and related processing and production operations, so everyone must make corresponding preparations in advance. Secondly, befor...
