Gas atomizing and spraying device

Abstract

The invention discloses a gas atomizing and spraying device which comprises a body and a plurality of storage tanks for storing high molecular raw materials, wherein the storage tanks are connected with the body, the top of the body is provided with a mixing unit connected with the storage tanks, the bottom of the mixing unit is provided with at least one unloading channel communicated with the mixing unit, the side wall of the body is provided with at least one gas inlet channel, the end part of the gas inlet channel is provided with at least one nozzle covering the tail end of the unloading channel, and the nozzle can disperse and atomize the mixed materials from the unloading channel. The gas atomizing and spraying device can be used for mixing, atomizing and spraying glue stock, and can spray an even glue film on the base plate of a coiled material, thereby greatly improving the utilization ratio of the viscose glue and the quality of the coiled material, protecting the health of operating personnel from threats and protecting the environment from pollution.

Description

technical field [0001] The present invention relates to a kind of gas energy atomization spraying equipment used for spraying viscose on the substrate when producing multi-layer polymer synthetic coils, especially, relates to a kind of equipment used for mixing various liquid glues, and then using airflow to spray A device that atomizes the mixed glue to form viscose fine particles and sprays the obtained viscose fine particles. Background technique [0002] Existing polymer synthetic coils, especially multi-layer polymer synthetic coils, such as artificial leather and various industrial conveyor belts, are generally coated with a layer of adhesive on the substrate by scraping or curtain coating. Then press the base material, and then heat for a long time or suck while heating to remove the solvent in the adhesive, and then obtain a multi-layer polymer composite coil. This process requires the use of a large amount of adhesive, and the solvent in the adhesive will affect th...

AI Technical Summary

Problems solved by technology

This process requires the use of a large amount of adhesive. The solvent in the adhesive will affect the health of the operator. If it is not handled properly, it will also pollute the environment, which does not meet the requirements of environmental protection.

Moreover, it is not easy to ensure the uniformity of the adhesive by scraping or shower coating, and the thickness of the final adhesive film is different, resulting in low quality of multi-coil materials.
