How to Test the Strength and Hardness of Acrylic Display Holders?

When customers receive an acrylic display stand, they generally only pay attention to the design and paste stability of the acrylic display stand, and often ignore the strength test of the acrylic display stand. Next we will teach customers how to test the strength of acrylic display stand. Acrylic brackets mainly reflect quality through appearance inspection points such as transparency, brightness, and surface finish, but some strength requirements are often ignored by ordinary buyers or users. The structural design and strength of the acrylic display stand are very important, which are related to the loss and service life of the display stand.

1. The surface hardness and toughness of the acrylic display stand are two important strength indicators

The hardness of the acrylic stand refers to the hardness of the object. Diamonds are the hardest of all natural substances and can be used to cut hard glass; toughness refers to the ability of an object to return to its original shape after being deformed. Although diamonds are hard, they have low toughness and are easily broken. Acrylic display stands have low hardness but good toughness. When heated, its bending ability is stronger than glass, but the surface is not as hard as tempered glass.

2. The relationship between hardness, toughness and quality of acrylic display stand

The higher the surface hardness of the acrylic display stand, the higher the scratch resistance; the better the toughness, the less likely it will be damaged. If some inferior acrylic display stands are processed with reused recycled materials, aging and yellowing, the toughness of the product is very poor, it will break with a little effort, and it will not be able to withstand falling. Hardness is one of the hard indicators for evaluating the quality of acrylic display stands. Compared with the acrylic display stand produced by the extrusion method, the acrylic display stand produced by the casting method has a higher hardness index, reaching an average of 90 degrees Rockwell hardness.

In addition to using a professional Rockwell hardness tester, is there a simpler, more intuitive and more lively method to detect surface hardness? In fact, many factories do not use professional hardness testers to accurately detect the surface hardness of acrylic display stands, but use a relatively simple comparison method: use a pencil to draw a horizontal line on the surface of the acrylic display stand with a force of about 1KG, and use a rubber Wipe it clean and see if there are any visible marks on the surface. The surface hardness of the acrylic display stand can be distinguished according to the label of the pencil. The surface hardness of acrylic display stands is generally divided into 2B, 1B, HB, H, 2H, 3H from low to high, and the acrylic display stand with surface hardness of 3H can be achieved. The surface hardness of the acrylic display stand produced by Mukey can reach the highest level between 2H and 3H, which is very scratch-resistant and has very good toughness.
