Abstract
The invention discloses an improved enamel non-stick process method, which belongs to the technical field of coatings and comprises the following process steps: (1) sintering the enamel at a high temperature of 830-850 ℃; (2) cooling to 600-650 ℃ to enable the enamel surface to be colloidal; (3) uniformly spraying atomized organic silicon, wherein the spraying pressure is 4-5 kg; (4) rapidly cooling the enamel surface to 450-480 ℃, and generating uniform pinholes on the surface; (5) uniformly spraying a layer of polytetrafluoroethylene; (6) and (5) standing and cooling. The improved enamel non-stick process method of the invention ensures that the enamel surface is not easy to be brittle any more and the polytetrafluoroethylene coating which is blocked in the pinhole and can not fall off has excellent non-stick property because the organosilicon is infiltrated into the enamel surface.
Description
Technical Field
The invention belongs to the technical field of coatings, and particularly relates to an improved enamel non-stick process method.
Background
The enamel has the excellent performances of high hardness, high temperature resistance, corrosion resistance, wear resistance, insulation, attractive appearance and the like, but has the defects of brittleness and adhesion, thereby influencing the use of the enamel.
Disclosure of Invention
The invention aims to provide an improved enamel non-stick process method, which solves the problems of frangibility and sticking of the existing enamel.
In order to achieve the purpose, the technical scheme of the invention is as follows: an improved enamel non-stick process method comprises the following process steps:
(1) sintering the enamel at a high temperature of 830-850 ℃;
(2) cooling to 600-650 ℃ to enable the enamel surface to be colloidal;
(3) uniformly spraying atomized organic silicon, wherein the spraying pressure is 4-5 kg;
(4) rapidly cooling the enamel surface to 450-480 ℃, and generating uniform pinholes on the surface;
(5) uniformly spraying a layer of polytetrafluoroethylene;
(6) and (5) standing and cooling.
The invention has the beneficial effects that:
the improved enamel non-stick process method of the invention ensures that the enamel surface is not easy to be brittle any more and the polytetrafluoroethylene coating which is blocked in the pinhole and can not fall off has excellent non-stick property because the organosilicon is infiltrated into the enamel surface.
Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments of the present invention, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
An improved enamel non-stick process method comprises the following process steps:
(1) sintering the enamel at a high temperature of 830 ℃;
(2) cooling to 600 deg.C to make enamel surface be colloidal;
(3) uniformly spraying atomized organic silicon, wherein the spraying pressure is 4 kg;
(4) rapidly cooling the enamel surface to 450 ℃, and generating uniform pinholes on the surface;
(5) uniformly spraying a layer of polytetrafluoroethylene;
(6) and (5) standing and cooling.
Example 2
An improved enamel non-stick process method comprises the following process steps:
(1) sintering the enamel at high temperature of 850 ℃;
(2) cooling to 650 ℃ to enable the enamel surface to be colloidal;
(3) uniformly spraying atomized organic silicon, wherein the spraying pressure is 5 kg;
(4) rapidly cooling the enamel surface to 480 ℃, and generating uniform pinholes on the surface;
(5) uniformly spraying a layer of polytetrafluoroethylene;
(6) and (5) standing and cooling.
Example 3
An improved enamel non-stick process method comprises the following process steps:
(1) sintering the enamel at a high temperature of 840 ℃;
(2) cooling to 630 ℃ to enable the enamel surface to be colloidal;
(3) uniformly spraying atomized organic silicon, wherein the spraying pressure is 4.5 kg;
(4) rapidly cooling the enamel surface to 460 ℃, and generating uniform pinholes on the surface;
(5) uniformly spraying a layer of polytetrafluoroethylene;
(6) and (5) standing and cooling.
The invention relates to an improved enamel non-stick process method, which is characterized in that after enamel is sintered at a high temperature, the temperature is reduced from 830-850 ℃ to 600-650 ℃, when the enamel surface is still colloidal, atomized high-temperature-resistant organic silicon is uniformly sprayed on the enamel surface under the pressure of 4-5 kg, the enamel surface is rapidly cooled to about 450-480 ℃ at the moment, uniform needle holes are generated, then a layer of polytetrafluoroethylene is sprayed, and the enamel is statically placed in a sintering furnace until the enamel is cooled.
The improved enamel non-stick process method of the invention ensures that the enamel surface is not easy to be brittle any more and the polytetrafluoroethylene coating which is blocked in the pinhole and can not fall off has excellent non-stick property because the organosilicon is infiltrated into the enamel surface.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
