Embodiment Construction

[0052] The following descriptions are only preferred embodiments of the present invention, and therefore do not limit the protection scope of the present invention.

[0053] Examples, see Figure 1 to Figure 4 As shown, a formaldehyde-removing plate environmental protection painting process includes the following steps,

[0054] In the painting step, a layer of paint is attached to the surface of the board through a spraying process, a roller coating process or a flow coating process; specifically, the primer is first rolled on the surface of the board by the roller coating mechanism of the roller coating device 1 of the painting equipment; The flow coating mechanism of the flow coating device 2 of the painting equipment paints a layer of topcoat on the surface of the plate.

[0055] In the low-temperature leveling step, the low-temperature leveling pre-heating device 5 is used for low-temperature heating, the paint is water-based and leveled, and the temperature is 100-250 d...

Abstract

The invention discloses a sheet material environment protection japanning technology free of formaldehyde. The sheet material environment protection japanning technology free of the formaldehyde includes a japanning step, a low temperature leveling step, an instant high temperature step, a cooling step and a low temperature keeping step. The sheet material environment protection japanning technology free of the formaldehyde enables sheet materials to rapidly pass through an instant high temperature heating area, not only can solidify and dry oil paint, but also can not damage the sheet materials, can not ignite the oil paint, can rapidly volatilize formaldehyde, ammonia, benzene and volatile harmful matter in the oil paint, enables no formaldehyde, no ammonia, no benzene and no volatile harmful matter to remain in the sheet materials and the oil paint, rapidly removes the formaldehyde, the ammonia, the benzene and the volatile harmful matter, which remain in the sheet materials, and saves energy and protects environment.

Description

technical field [0001] The invention relates to the technical field of board painting technology, in particular to an environmentally friendly board painting technology for removing formaldehyde. Background technique [0002] In the prior art, the board painting process is to attach a layer of paint on the surface of the board by spraying or rolling paint. The standard specification of the board is 1.2X2.4 meters. For this standard board, the paint It is difficult, and the paint inevitably contains a large amount of toxic and volatile substances, including formaldehyde, ammonia and benzene. After the board is painted, the paint on the surface of the board still contains a large amount of toxic and volatile substances. The existing technology cannot quickly remove these toxic and volatile substances remaining on the board, so it is necessary to improve it. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is...
