Product Description

In order to improve the heat dissipation and chip tolerance of the grinding tool and improve the grinding quality, a certain substance is usually introduced into the grinding tool to promote the generation of pores. Such substances that promote the generation of pores are pore formers. The solid pore-forming agent includes refined coriander, brown fused alumina price charcoal (or coke), walnut shell, plastic ball, hollow alumina ball, etc. the liquid pore-forming agent is mainly hydrogen peroxide (H2O2). It is used to decompose during the drying process to generate air bubbles and make the mill With pores.

There are two methods to control the density of ceramic abrasives by machine pressing: fixed mold method (constant volume) and constant pressure method. There are also two types of formulas. The characteristics of the fixed-mold formula table are that the mass of the black aluminum oxide particles is 100 parts, and the binding agent and the bonding wetting agent are all percentages of the mass of the abrasive particles. All the formula numbers are listed in the same table, and the organization number is in the table. Based on the structure number (grit ratio) and other data, the molding density can be calculated.

For grinding wheels with smaller holes and thinner thickness, drilling is generally used to process the holes, and drilling is performed on a drilling machine. During the operation, the processed grinding wheel is placed on the grinding wheel table, the main shaft is started to rotate, and the drill bit lifting handle is pulled, so that the drill bit enters the hole of the processed grinding wheel for drilling. The drilling tools are mainly drill bits and corundum. It is used to process various sulfurized cements with graphite powder in brown. It is used for the filling of brown corundum and silicon carbide grinding wheels.

Sintered corundum abrasives have a compact structure, high strength and hardness, and can maintain sharp cutting edges and correct geometries permanently during the grinding process. Sintered corundum abrasives, like ordinary abrasives, include three types of grinding wheels, grinding heads and grinding stones. These types of pink aluminum oxide generally do not differ in particle size, degree, and binder. Grinding tools made of synthetic resin or natural resin as a binding agent are called resin binding grinding tools, referred to as resin grinding tools.

The fused chrome corundum brick and sintered chrome corundum brick belong to the same chrome corundum products, but the color of the products produced by them is different due to different production process and different raw material ratio. The minor mineral composition is a small amount of composite spinel (or no composite spinel) and refractory brick with 1% - 30% chromium oxide content. There are two kinds of chrome corundum products: fused chrome corundum brick and sintered chrome corundum brick. There are two types of pore-forming agents: solid and liquid.

From the cost of materials, green silicon carbide, black silicon carbide and white corundum can be made around these abrasives. Inorganic grinding tools, including magnesite, ceramics, etc.; organic grinding tools, including phenolic, unsaturated resin, and epoxy (including abrasive cloth and sandpaper), constitute the grinding tools of ordinary aluminum oxide abrasive. Diamond abrasives belong to superhard abrasives, although its processing history is relatively long. Corundum refractories belong to high quality and high efficiency products.

Corundum refractory products, especially special corundum refractory products, i.e. high temperature ceramics, are produced not only in refractory industry, but also in building materials, electronics, chemical industry, machinery and other industries. The developed countries seek for high-purity raw materials, among which high-purity corundum raw materials are one of the key products. Al2O3 is an ionic crystal with stable structure. The precision analytical balance is usually used for weighing, with the measurement accuracy of 0.1mg.

Generally, abrasives have such properties, and the abrasiveness of white corundum abrasives is more ideal, which is mainly related to the properties of their materials. The application characteristics of glass sand are relatively obvious, and the outer packaging is used for decoration, and aluminium oxide grit suppliers has gained a lot of recognition. Pure silicon carbide is generally non-conductive, but if the proportion of carbon and silicon is appropriate, it can become a semiconductor.  At high temperature, the volume of the binder begins to shrink and the porosity begins to decrease due to the melting of the low melt.
