Types and effects of abrasives
An abrasive is an abrasive article containing a friction material and is an adjuvant for the paint surface grinding process. Generally speaking, it is a mixture made of abrasives, dispersants (also known as grinding liquids) and auxiliary materials, and is also customarily classified as a type of abrasive tools. The abrasive is used for grinding and polishing, and the abrasive particles are in a free state when used. Due to the different composition and mixing ratio of the dispersing agent and the auxiliary material, the abrasive has a liquid state, a paste form, and the like.
The classification of abrasives can be divided into ordinary abrasives and clearcoat abrasives depending on the scope of use. Common abrasives are generally used as friction materials. According to the size of the rock particles, they are classified into deep (or weighed), medium (or moderate) and micro (or light). The three types are mainly used to deal with paint defects such as oxidation, scratches and fading of ordinary paints.
