Problems solved by technology

[0003] With the rapid development of the enamel industry, various new requirements have emerged for the performance of enamel in various aspects. In the preparation of traditional wet glaze slurry, adding clay as a suspending agent is an indispensable part, but at present All kinds of bentonite and Qingshan clay on the market will have a weak influence on the glaze color of pure base glaze, which makes it difficult to realize the color of some enamel. Some pure titanium glazes are prepared by grinding with normal clay. The color after firing is yellowish, and the deployment of cool tones cannot be further realized. In the case of cool tones, it is difficult to ensure the operability of the glaze slurry, and it is impossible to take into account the cost issue

Embodiment 1

[0019] Weigh the raw materials according to the following proportions: pure titanium glaze TMW 170:100g, Foshan Puji brand suspending agent methylcellulose mixture UC-D1: 8g, potassium chloride: 0.2g, water: 45g, mix well and place in a fast ball mill The glaze slurry produced by upper grinding for 12 minutes was sprayed on the normal enamel plate, the thickness of the enamel layer was 80 μm, and the firing process was 800 ° C for 4 minutes to obtain an enamel steel plate. The specific performance parameters of the obtained steel plate are shown in Table 1.

[0021]

[0022]

[0023] It can be seen from Table 1 that the properties of the enamel steel plate made by UC-D1 meet the standard requirements, and the construction performance is good, which can be applied in the production of enamel.

Embodiment 2

[0025] Weigh each raw material according to the following proportions: pure titanium glaze TMW 170:100g, suspending agent: 7.5g, potassium chloride: 0.2g, water: 45g, wherein, suspending agent is respectively: 1, EZ957V clay, 2, Bailong brand Kaolin, 3. Duomad's 18# clay, 4. Puji's UC-D1, after mixing evenly, grind it on a fast ball mill for 12 minutes. The glaze slurry produced is sprayed on the normal enamel plate, and the thickness of the porcelain layer is 90μm , and the firing process was 800°C for 4 minutes to obtain enamelled steel plates. The performance parameters of the obtained four groups of enameled steel plates are shown in Table 2.

[0026] Table 2 Performance test results of four groups of enamelled steel plates

[0027]

[0028]

[0029] It can be seen from Table 2 that the color of the enamel steel plate prepared by enamel suspending agent UC-D1 is the lightest after comparison in the same direction, and the effect is better than that of the conventiona...

Embodiment 3

[0031] Weigh each raw material according to the following ratio: pure titanium glaze TMW 170:100g, suspending agent: 8g, potassium chloride: 0.2g, water: 45g, wherein, suspending agent is respectively: 1, EZ957V clay 4g, UC-D14g, 2 , Kaolin 4g, UC-D14g, 3, 18# clay 4g, UC-D14g, after mixing evenly, grind it on a fast ball mill for 12 minutes to make the glaze slurry spray on the normal enamel plate, the thickness of the porcelain layer is 100μm, and fire The process is 800°C for 4 minutes to produce enamelled steel plates. The performance parameters of the three groups of enameled steel plates obtained are shown in Table 3.

Abstract

The invention discloses an enamel suspending agent and an enamel steel plate with the enamel suspending agent. The enamel suspending agent is prepared from the following components in parts by weight:7.5 to 8.5 parts of a base material, 0.2 to 0.5 part of electrolyte and 40 to 50 parts of a solvent. The enamel suspending agent disclosed by the invention has the characteristics of good dispersity,high suspending rate, good dispersity in water, small particles, great surface activity, strong penetrability, no dust in a preparation process, low cost and the like; water is used as a dispersion medium and the problem that toxic and harmful substances are easily generated by an organic solvent is not caused; after the water is added to dilute the components, the suspension property is good andthe physical stability of glaze slurry can reach the optimal effect. After the enamel suspending agent disclosed by the invention and pure titanium glaze are uniformly mixed, a mixture is ground to prepare the glaze slurry; then the glaze slurry is sprayed on an enamel plate block and then the enamel plate block is fired to prepare the enamel steel plate; all performances of the prepared enamel steel plate can meet standard requirements and the construction performance is good.

Description

technical field [0001] The invention relates to a suspending agent and its application, in particular to an enamel suspending agent and an enamel steel plate with the same. Background technique [0002] The mechanism of action of suspending agent is to reduce the interfacial tension between liquid-liquid or solid-liquid by adsorbing on the surface of solid particles. Make the surface of condensed solid particles easy to wet. At the same time, an adsorption layer is formed on the surface of the solid particle, which increases the charge on the surface of the solid particle and increases the reaction force between the particles forming a three-dimensional barrier. As a result, a bimolecular layer structure is formed on the surface of the solid particles, and the polar end of the outer dispersant has a strong affinity with water, which increases the degree of wetting of the solid particles by water. Solid particles are separated by electrostatic repulsion. Finally, the syste...
