The use of boron nitride lubricating material significantly improves the lubricating and demolding effect. At present, the most widely used boron nitride release agents are mainly divided into the following three categories:

The first type uses water as the medium, adding additives such as high-temperature adhesives to make water-based lubricants, which are brushed on the surface of the mold at one time, dried to form a film, and used.

The other type uses oil as the medium, adding additives to make oil-based lubricants, and continuously brushing or spraying during the operation of the determinant bottle making machine.

A commonly used boron nitride release agent is to coat high-viscosity mineral oil with boron nitride, and add water under the action of an emulsifier to make an emulsified oil-type glass mold lubricating release agent. Boron nitride: oil: water = 1: 4: 10, when the amount of emulsifier is 7 wt%, the prepared emulsified oil release agent has good stability, good release performance, and has the characteristics of thin oil film and uniform distribution. The use of boron nitride lubricating mold release agent improves the yield of bottle making, reduces the consumption of lubricating mold release agent, and purifies the production environment.

Boron nitride mold release agent can also be used in flat glass processing, which can greatly improve the working environment and improve product efficiency. Especially for curved glass processing, the effect is more significant.
