Steel ball hardness refers to the ability of the steel ball to locally resist the pressing of hard objects into its surface. Steel ball hardness is usually expressed by HRC, and some countries use HB. We highlight the Rockwell hardness HRC: HRC: It is a hardness obtained by using a 150kg load and a ... read more
There are many types of plastic balls according to their materials, engineering plastics balls of thermoplastics, soft plastic balls of elastomers, thermosetting plastic balls of phenolic resins, PVC slush plastic balls of liquid molding, and large-sized plastic rods. Machine-added plastic balls. Du... read more
1. Plastic hollow spheres are generally made by bonding two semi-circular hollow spheres, so the accuracy of plastic hollow spheres is not high. This type of hollow sphere is mainly used as a liquid surface covering ball, in order to prevent evaporation of chemical and chemical agents. Cause environ... read more
Plastic ball pressure test is to determine the resistance of plastic ball to another accessory that matches plastic ball. It has the ability of a rigid object with no elastic deformation to press it. It is one of the important parameters to check whether plastic ball can be deformed without cracking... read more
Plastic pellets are also called plastic microbeads. Degradable plastic pellets are mainly used in the cosmetics industry, but traditional plastic pellets cannot be biodegraded, causing environmental impact. Very large pollution. At present, it is strictly prohibited to use non-degradable plastic pel... read more
