What’s difference between black silicon carbide P sand and black silicon carbide F sand:
Different production processes:
P sand and F sand, the same period of the production process, the second processing of P sand requires multiple models mixed sieves P sand is basically high. Generally, it is distributed in granularity according to customer requirements, that is, to remove the middle F sand is international standards
The difference between granularity distribution:
The particle size distribution of F sand must meet the requirements specified in the national standard GB/T 2481.1-1998.
The granularity distribution range of P sand is narrower, and it must meet the requirements of the national standard GB/T9258.2-2208.
The difference between use: F sand can be used for the production of sand spray and solid abrasives such as sand wheels.
P sand is more used for production of abrasives (such as sasal belts and sand cloths).
