Remove Salt from Rubber Extrusion
Recently our customer, who owns a company that manufactures door and window seals, contacted us. His company uses a salt potassium nitrate to cure and produce a gloss finish of rubber extrusion which is used as build inside doors and windows. Using conveyor rollers, the rubber extrusion travels through a bath with the salt potassium nitrate and then moved outside to dry.
After a short talk with the customer it was apparent that the same salt used in the production of the rubber extrusion was also adhering to the strip, spoiling the appearance of the final product and also causing maintenance issues by sticking to the conveyors used to transfer the rubber extrusion. The topping up of the salt in the bath is hazardous and needs to be kept at a minimum for safety reasons.
I suggested the installation of two Advanced Air Knife above the conveyor and see if the results were satisfactory.
The customer called us back 5 days later and told us that the Air Knives performed perfectly. Both air knives blew the water out in a much shorter time. Installation of the Air Knives allowed for the following:
- Reduced in amount of salt that is used in production
- Reduced maintenance
- Increase safety in the production line
- Improve quality of the final product
