Low-polymerization prepolymers of aluminum oxide abrasive thermosetting resins are generally viscous liquids. This viscous liquid is added with a curing agent (or no curing agent), and heated to a certain temperature, and cured to become an insoluble and insoluble hard solid. When it rises, the resin can no longer soften, such as garnet abrasive phenolic-epoxy; phenolic-new phenol ; but can only gradually decompose. The most commonly used artificial resins are phenolic resins.

This type of resin generally has high heat resistance and is not easily deformed under black corundum pressure, but its mechanical strength is generally low, and its strength must be improved by adding fillers and other measures. At present, resin abrasive tools are manufactured at home and abroad. There is a special fan-shaped discharge valve at the bottom. There are two perspective holes on the kettle cover for holes for clearing the kettle and for silicon carbide abrasive sampling, and various connections.

(cheap brown fused alumina suppliers uk)These pink corundum resins include phenolic resins, neophenol resins, epoxy resins, unsaturated polyester resins, and polyimide resins. Thermoplastic resin is generally solid at normal temperature. This solid resin will soften with increasing temperature within a certain temperature range, and will harden after cooling, and will still become soft after heating. constant. These green silicon carbide resins have good mechanical properties at room temperature, but they have poor heat resistance and rigidity.

 The resin powder can be dissolved in ethanol, butanol, brown fused alumina acetone, furfural and the like. In addition, there are also epoxy resins, new phenol resins, polyfloating resins, polyvinyl acetals, polyamides, and polyimides. In order to meet the requirements of some special black silicon carbide products and improve the performance of abrasive tools, in recent years, a blend of phenolic resins and a certain amount of other resins has been used as a binder, Phenol-polyamide; phenol-poly.(cheap brown fused alumina suppliers uk)

The rhenium reactor is the main equipment for carrying out the polymerization reaction. Since the brown aluminum oxide polycondensation reaction is performed in an acidic or alkaline medium, the reaction kettle should be made of corrosion-resistant materials (such as sugar porcelain or stainless steel). The kettle body is an oval double-layer structure, and steam or cooling water can be passed in the kettle. The kettle is equipped with an anchor stirrer, aluminum oxide grit which affects the use.

(cheap brown fused alumina suppliers uk)Condenser is a tube-type device for heat dissipation during brown aluminium oxide condensation reaction and condensation and dehydration during resin drying. The heat exchange area depends on the volume of the reaction kettle. On average, the condensation area of each cubic meter is 10-15m. In order to facilitate assembly, cleaning, and sticky repair, the synthetic corundum condenser should be installed at an angle of 10 ° ~ 30 °. A sink is a device that receives condensate.

Phenolic resin powder uses phenol and formaldehyde (molar ratio of 1: 0.8 ~ 0.9) as white alumina raw materials, hydrochloric acid (amount of 0.1% ~ 0.3% of phenol amount) as catalyst, heat-condensates to form thermoplastic phenolic resin block, and then crush , Filtered. Phenolic resin powder is a white or light yellow translucent solid powder at room temperature. In the air, it is easy to oxidize to deepen the color, and it is easy to absorb moisture and emery abrasive agglomerate.(cheap brown fused alumina suppliers uk)
