NOVA provides customers with designing and manufacturing equipment ranging from a few hundred kilograms of small single-machine to tens of thousands of tons of water-based coating equipment each year. There are three types of products which are water - soluble coating, water - diluted coating and water dispersive paint (emulsion paint). In addition, there are also water soluble alkyd resin, water soluble epoxy resin and inorganic polymer waterborne resin. Water-based coating equipment adopts automatic material feeding system, measuring system, decentralized grinding system, multi-function mixing paint system, cleaning system, automation control system, automatic filling and other advanced production methods. It is a fully automated production process. It alleviates the working strength of the operator and avoids the quality problems caused by human factors, which greatly improves the product quality and production efficiency.

NOVA provides customers with designing and manufacturing equipment ranging from several hundred kilograms of small single-machine to tens of thousands of tons of oil coating equipment each year. Our products include nitrocellulose lacquer, polyurethane paint, enamel paint, varnish, anti-corrosive paint, gloss finish, epoxy paint, etc. Oily coating equipment adopts automatic material feeding system, measuring system, dispersion system, grinding system, paint system, discharge and filtration system, filling system, automation control system, operation platform and paste production parts. It is a fully automated production process, which has high efficiency and adopts international advanced disperse grinding system. The product has good fineness and stable quality.

Working Principle

The production process of Water-based paint is divided into the following parts: batching, dispersion, grinding, paint mixing, filtering and filling.

Batching: Liquid ingredients adopt pumps and flow-meters. Weighing system and gas conveying are used in powder ingredients. The auxiliary ingredients adopt weighing measurement and gravity.

Dispersion: The first process of pulping is to disperse the powder material into the liquid rapidly and evenly through the high-speed dispersing machine, forming the white pulp with no agglomeration and uniform mixing.

Grinding: The secondary process of pulping is to grind the white pulp to the desired fineness by German technology superfine grinder.

Paint mixing: The process of adding emulsion, color paste and additives to the prepared slurry to evenly mix through single shaft or multi-function paint mixing vessel.

Filtering: Finished product will be filtered by bag filter or self-cleaning filter.

Filling: Filling the filtered finished product, and filling specifications are usually 10-25kg. Semi-automatic or full-automatic filling machine can be selected.

The production process of oil paint is divided into the following parts: batching, dispersion, grinding, paint mixing, filtering and filling.

Batching: Liquid ingredients adopt pumps and flow-meters. Weighing system and gas conveying are used in powder ingredients. The auxiliary ingredients adopt weighing measurement and gravity.

Dispersion: The powder liquid is quickly and evenly dispersed into the liquid through a high-speed disperser to form a slurry with no agglomeration of powder and uniform mixing; A variety of forms and specifications are available, including scraping wall type disperser, vacuum type disperser, double shaft disperser (butterfly+dispersion), platform type disperser and other products, meeting the requirements of various dispersion and mixing conditions;

Grinding: We choose the international advanced grinding technology. The horizontal sand mill is mainly used in the production line. The basket mill is mainly used in the color slurry production.

Paint mixing: According to different painting processes and material properties (viscosity, specific gravity, etc.), there are many types and specifications of mixers available, including vacuum, explosion-proof, single shaft, double shaft, triple shaft, etc.

Filtering: Finished product will be filtered by bag filter or self-cleaning filter.

Filling: Filling the filtered finished product, and filling specifications are usually 1-5kg and 10-25kg. Semi-automatic or full-automatic filling machine can be selected.
