Firecracker solid primer is a dry powder which plays a role of solid priming and sealing in the process of firecracker forming. The traditional fixing agent for firecrackers is mostly made of earth powder, halogen, silica sand and other raw materials. It has poor physical and chemical stability, is prone to loose phenomena and has a long curing time. It is not only low in production efficiency, but also easy to damage the lead and reduce the quality of firecrackers.

The new magnesite firecracker solid primer can completely overcome the above shortcomings, the specific advantages are as follows:

1. Fast solidification. The new magnesite firecracker solidification primer uses light burned magnesia ball and magnesium chloride as the main raw materials. It has uniform moisture regain and fast solidification, which can effectively improve the production efficiency of firecrackers.

2. The performance is stable. The new magnesite firecracker solid primer has high strength, good stability, no moisture absorption and halogen return, no loose phenomenon, and good use effect.

3. Easy to use. The new magnesite firecracker fixing primer is easy for workers to operate when it is sealed, and it is not easy to damage the lead. It can realize large-scale processing and production of firecrackers.

Firecracker sealing powder, sealing powder is made from light burned magnesia ball (earth powder, light burned powder, bitter soil powder) as the main raw material, adding halogen sand and other raw materials into plastic bags through machine mixing and stirring, a raw material for firecrackers. Magnesium oxide is used for sealing powder of firecrackers. It is not too fine. When sealing powder is too fine, the dust is too big, which is not conducive to use.
