How To Adjust The Hardness Of Modified Plastics?
Hardness refers to the ability of a material to resist other hard objects into its surface,
The size of the hardness value is a qualitative quantitative representation of the soft and hard degree of the material. It is not a simple and definite physical quantity.So what’s the hardness of the modified plastics?How to improve the hardness of modified plastics?
The magnitude of the hardness value depends not only on the material itself, but also on the test conditions and the measurement method. It means different hardness measurement methods, the same material measured hardness values are not the same. Therefore, to compare the hardness between the materials, it is necessary to measure the hardness with the same method of measurement.
There are several methods commonly used to indicate hardness:
A Shore Hardness
B Rockwell Hardness
C Moh’s Hardness
Add hardness of modified plastics
The hardness of adding modified plastics refers to a modification method for adding hard additives in plastics. The common hardness filling agents are rigid inorganic fillers and fibers.
Surface treatment to improve the hardness of plastics
Plastic surface hardness improvement means only to improve the hardness of the appearance of plastic products. The hardness of the interior of the product is unchanged. This is a low cost method for improving hardness.
The modified method is mainly used for shells, decorative materials, optical materials and daily necessities, etc.. The modified method mainly includes two methods:
coating and surface treatment.
