FEPA-F, There are multiple standard versions for grain sizes. The European FEPA (Federation of European Producers of Abrasives). Within the FEPA sizes, you can also distinguish between FEPA-P and FEPA-F. F sand is an applied particle size specification for abrasives and refractory materials. The particle size numbers are: F4, F5, F6, F7, F8, F10, F12, F14, F16, F20, F22, F24, F30, f36, F40, F46, f54, F60, F70, F80, f90, F100, F120, F150, F180, F220, F220, F230, F240, f280, F320, F320, f280, F320, F320, f280, F320, F360, F400, F600, F800, F1000, f1200. Among them, f4-f220 is called “grit size,” which is produced by screening, and f230-f1200 is called “micro powder,” which is produced by multi-purpose water separation, airflow and ultrasonic circular vibrating screen
Glue – A system where both coats are made of animal glue is used when the strength of the bond is not an important factor, such as with lightweight papers and materials. Phenolic Resin – This system uses full phenolic resin for both coats. It is designed to withstand moisture
The specific weight is the ratio of the weight of a body to its volume. The specific weight of corundum under normal conditions is 3.94 g/cm3.
Raw materials containing aluminium oxide are electrothermally melted at a reaction temperature of more than 2,000 °C to produce the various fused aluminas. Different starting materials are used depending on the desired type of fused alumina. For instance, bauxite is used for the manufacture of brown and semi-friable fused alumina,
fused aluminum oxide products do not have a known shelf life. As long as the product is maintained in the original sealed container and stored in a cool, dry, ventilated area, our product will last indefinitely
This decision is made by the type of abrasive you have selected or the type of process you will be performing. Glue – A straight animal hide glue that is used to adhere the abrasive particles to the backing. Referred to as “Glue Bond”. Resin – A synthetic resin that
When functionalising fused alumina, a very thin layer of a silane adsorption group is applied to the fused alumina particles. This organic surface coating has the effect of better embedding and increased scratch resistance in a melamine resin matrix, for example. Fused alumina has a high refractive index (n =
