Application of lignin sulfonate and other inhibitors in molybdenite

Lignosulfonate is a by-product of papermaking. Each ton of pulp produced produces one ton of lignosulfonate. The chemical structure is unclear. It only knows that it contains many hydroxyl groups, phenol groups, methoxy groups, and high genus. Molecular polymer. It is widely used as a flotation inhibitor. The US Bimodal copper - molybdenum mine suppresses molybdenite with a molybdenum distribution rate of more than 90%.

Also available as molybdenum inhibitors: starch, tannins, anionic polymers, etc., but are rarely used.

Now more people use pu insulated shutter to replace metal shutter door.It has many advantage such as anti corrosion,stronger,little noise.

Pu insluated garage door forming machine is automatic with HMI,different orders can be done.Saves more labor.

The final product can be cut as per set length controller,and the length is automatically measured by encoder.When final product reached set length,machine will stop to cut the sheet automatically.Finish thhis action,the machine will run again continuously
