Embodiment 1

[0023] Embodiment 1: as figure 1 As shown, the raw lacquer atomization method uses a pneumatic paint spraying device for atomization; a spray gun 3 with a nozzle size of 0.4mm to 2.5mm is used; the pressure during the atomization process is 5Pa to 13Pa higher than the ambient air pressure; raw lacquer itself is a high Molecular compound is also a typical non-Newtonian fluid, its viscosity will change under the action of shear force; raw lacquer belongs to the expansion fluid in non-Newtonian fluid, and its viscosity value increases with the shear force and increase; when a small shear force is applied, the raw lacquer cannot flow, and only when the added shear force exceeds a certain value can it start to flow; if the raw lacquer is sprayed with a high-pressure pump, the viscosity of the raw lacquer will increase. As a result, it is difficult to atomize, and even blockage of pipes and nozzles may occur; and if no pressure is applied to the raw paint, it cannot be sprayed out t...

Embodiment 2

[0027] Embodiment 2: as figure 1 As shown, the raw lacquer atomization method uses a pneumatic paint spraying device for atomization; a spray gun 3 with a nozzle size of 0.4mm is used; an air pressure of 5Pa is added during the atomization process; if the pressure applied during the atomization process is less than 5Pa, the raw lacquer cannot be made If the flow is generated, if the nozzle size of the spray gun 3 is lower than 0.4 mm, the raw lacquer cannot be sprayed out.

[0028] The pneumatic paint spraying device includes an air compressor 1, a pressure tank 2 and a spray gun 3; the air compressor 1 is connected to the pressure tank 2 through the first air pipe 6; the spray gun 3 is connected to the pressure tank 2 through the feed pipe 8 The discharge port is connected; the spray gun 3 is connected with the pressure tank 2 through the second gas delivery pipe 7.

[0029] The air compressor 1 is an air compressor. Its principle is to provide air source power. It is the co...

Embodiment 3

[0030] Embodiment 3: as figure 1 As shown, the raw lacquer atomization method uses a pneumatic paint spraying device for atomization; a spray gun 3 with a nozzle size of 2.5mm is used; an air pressure of 10Pa is added during the atomization process; during the atomization process, if the nozzle size of the spray gun 3 used is greater than 2.5mm , even if it is sprayed from the spray gun 3, the raw lacquer cannot be atomized; if the applied pressure is higher than 13Pa, the viscosity of the raw lacquer will increase, which will affect the atomization effect and even fail to be sprayed;

[0031] The pneumatic paint spraying device includes an air compressor 1, a pressure tank 2 and a spray gun 3; the air compressor 1 is connected to the pressure tank 2 through the first air pipe 6; the spray gun 3 is connected to the pressure tank 2 through the feed pipe 8 The discharge port is connected; the spray gun 3 is connected with the pressure tank 2 through the second air pipe 7;

Abstract

The invention discloses a raw lacquer atomization method. The raw lacquer atomization method comprises the following steps of atomizing by using a pneumatic paint spraying device; filtering raw lacquer by using a 200-2000-mesh sieve; heating the raw lacquer to 30-90 DEG C; and adopting a spray gun with a nozzle size of 0.4-2.5 mm, wherein the pressure in the atomization process is 5-13 Pa higher than the ambient air pressure value. The technical scheme adopted by the invention solves the problem that the raw lacquer cannot be in an atomization state under the condition of not using any additive.

Description

technical field [0001] The invention relates to the application field of raw lacquer, in particular to a raw lacquer atomization method. Background technique [0002] Raw lacquer is a milky white pure natural liquid harvested from lacquer trees. It is mainly composed of urushiol, polysaccharides, glycoproteins, laccase and water. It is the only latex known to man that can be cured into a film under the catalysis of protease. shaped natural paint. The enzymatically initiated urushiol radical oxidative polymerization characteristics and the supramolecular interaction of urushiol-polysaccharide-protein make the raw lacquer coating have outstanding physical and chemical properties such as anti-corrosion protection, anti-oxidation, high temperature resistance, and wear resistance. Unprocessed raw lacquer has thick paint and high water content, which will affect the painting performance. The viscosity of raw lacquer is high, it is not easy to brush, and it is impossible to achie...
