Celluloid for Military Industry
What is celluloid and what is the production process of celluloid?
- Celluloid is a cellulose nitrate plastic with camphor as a plasticizer, which is processed into plastic products through thermoforming. Due to the nitration, the finished product is extremely flammable.
- Through the addition of various pigments and additives, plastic manufacturers produce sheets and plates with a strong three-dimensional sense, improving their flammability, strength, durability, geometric stability, and other properties to a certain extent.
The use of celluloid in the military industry
Due to their use environment and intended functions, military shells, made of nitrocellulose as the basic raw material, nitro film and celluloid board products, have good adaptability to special environments, are resistant to moisture, acid and alkali, have good sealing properties and have certain strength, making them extremely suitable for the launch systems of medium and large caliber weapons.
Used in nitro cartridge and production processes
Use acetone solution to compound the base film and industrial cotton cloth on a compounding machine, cut the compounded semi-finished product into 15x15cm sheets, put the punched sheets into a drying machine for 12h~24h, and then install them on a sheet forming machine for forming. We keep the holding time at 3 minutes and the water temperature at 80°C ~100°C. Place the prepared glue solution in proportion for 24 hours. We apply the glue solution around the half box and then place it in the mold of the bonding machine for pressing. The bonding holding time is 1min. The inspector examines the dried medicine boxes after they are punched out from the trimmed and bonded ones for 0.5h~12h.
Nitro shell and production process
For medium and large caliber weapon launch systems, the inner wall of the combustion chamber or the porous plate at its lower end is pasted or papered with a powder package wrapped in a celluloid shell.
Celluloid Manufacturer
As a special material, celluloid has a wide range of applications in the military industry. However, due to the complexity of the production process, few factories are able to produce it. As manufacturer of celluloid, after long-term research and testing, our quality is very reliable. If you need a sample or quotation, please contact us directly.
