Huitai 30# Garnet Polishing Sand Sandblasting Materials


1. Product Introduction

Garnet sand, ground from garnet ore as raw material, is characterized by high hardness, high temperature resistance, stable chemical properties, uniform particles, high grinding efficiency and less scratching. It is suitable for various metal materials, non-metal materials, plastic and other surface sandblasting treatment industries.

Common particle size(Can be customized according to customer requirements)

2. Characteristics

①The texture of garnet sand is hard, with a Mohs hardness of more than 7.1, which is higher than that of commonly used quartz sand, sea sand, river sand and other sandblasting materials, and has a long service life.

②Because garnet is a crystal of an isometric system and has no cleavage, which it is easy to form approximate cube particles with edges and angles after making it into sandblasting, and the effect of sandblasting and rust removal is better. It can not only completely remove the rust, oxide skin, coating and its pollutants on the metal surface, but also because of its high hardness, it can produce an ideal angular rough surface on the cleaned metal surface, increasing the surface area of the metal, improving the adhesion of the interface, and making the binding force of corrosion-resistant protective coating and the metal surface significant. So it can enhance to improve the bonding performance of the coating and the metal surface.

③The density of garnet sand is larger, usually about 4g/cm³, strong impact force, which can better clean the metal surface.

④High strength. Treating the metal surface,garnet sand is not easy to break. Even after it is broken, it will produce new angular, almost cubic particles, so that it can be used repeatedly, usually up to 20 times. It is 20 times of siliceous sand (sea sand or river sand) and more than 2 times of quartz sand (artificial), and its relative cost is low once used.

3. Application

①Surface pretreatment of metal materials and non-metal materials structural parts, etc.
This is one of the more widely used fields of garnet sandblasting. It can be used for electroplating, spray painting, spraying and other all covered before sandblasting processing, which can achieve a clean surface, and improve the roughness of the substrate surface, enhance the adhesion of the coating, extend the life of the coating, especially for ships and other large equipment.

②Workpiece surface cleaning
It is mainly used to remove dirt and impurities on the surface of objects,workpiece rust removal, such as casting parts, stamping parts, welding parts, heat treatment parts and other metal work pieces and oxide skin, residue, dirt; Cleaning surface of non-metallic products, removing the black spots on the surface of ceramic embryo.

③Processing glitch
The micro burr of machined parts is removed, and the rubber overflow of injection parts is eliminated. It can be said to be a correction to make the workpiece more beautiful light finishing process.

④Refurbishment of old workpieces
For the refurbishment and cleaning of all moving parts such as automobiles, motorcycles, electromechanical equipment, etc., garnet sand can also be used, which can not only restore the metallic luster of the workpiece, but also have no problem of sand inlaying. At the same time, it can also eliminate the fatigue stress of workpieces and extend their service life.
