Which steel plate is better, enamel steel plate or aluminum plastic plate? Steel plate is based on Baosteel steel plate, which is made by a series of processes such as welding, bending, glaze spraying and high temperature firing. Advantages are fireproof, waterproof, moisture-proof, corrosion-resistant, weather-resistant and impact-resistant. Enamel steel plate can be used in tunnels, subway stations, railway stations, banks, airports, shopping malls, hospitals, factories and other buildings. The enamel on the surface of the enamel steel plate is treated by a special process, so that the light shining on the plate will not be dazzling, and the light will be soft and will not irritate the eyes.
Before the manufacturing process of enamel steel plate was revealed, we knew the simple price of an enamel steel plate. This time, Bian Xiao will show you the production technology of enamel steel plate. We mentioned that the enamel steel plate is a composite material, so the manufacturing process is relatively more complicated, but the material has good performance and beautiful appearance, and can be used in many different places. Then let's get to know the manufacturing process of this enamel steel plate.
First, the condition of enamel steel plate;
1. The carbon content is 0.08~0. 12%.
2. The surface structure is uniform
3. Suitable for stretch forming, not easy to crack and wrinkle.
4. Suitable for welding and easy to clean.
5. It is not easy to deform and bend during firing. At present, the commonly used plates and models in China are Baosteel BTC 1 Maanshan SPCC- 1DC0 1 etc.
Second, the conditions required for the bottom glaze
1 tightly combined with steel plate.
2. Good fluidity during firing.
3. The firing temperature range is wide, and it is more resistant to firing.
4. The thermal expansion coefficient is appropriate, and it is not easy to produce cracks and deformation after firing.
5 has certain explosion-proof performance.
Grinding AIDS in Basic Glaze Formula and Their Functions
1, clay 2, time 3, electrolyte (nitrosborate)
The role of clay:
1 As a suspending agent for enamel, it plays a suspending role.
After the enamel is dried, the enamel particles are fixed on the metal blank.
Clay can adjust the physical structure and expansion coefficient of enamel during firing.
Clay will affect the hiding power, whiteness and luster of enamel.
Electrolyte: nitrite: rust-proof. Generally, 0.2-0.5% borax plays a fluxing role, and 0.3-0.5% is used.
The standard thickness of steel plate enamel bottom glaze is 80~ 120um, and the initial glaze is 120~ 150um.
Surface glaze: Surface glaze can be divided into basic glaze and titanium glaze.
Basic glaze is mainly used for color matching. The basic glaze needs to have good luster, porcelain surface and glue resistance, and it is not easy to produce adhesive film printing after decal.
White glaze should have good hiding power, luster and acid resistance.
The thickness of surface glaze is generally 150~200um.
Test index and method of glaze slurry;
1 particle size (thickness) 2 specific gravity (dissolved weight) 3 retention (adhesion)
Glaze slurry particle size test
Put 50 ml of glaze slurry on a 200-mesh screen, rinse with water, and dry the remaining porcelain powder.
Standard granularity: bottom price: 6-8g surface glaze: 3-5g color glaze: 2-4g.
Specific gravity:
Take 100 ml glaze slurry in a specific gravity bottle (bottle weight is 50g), and subtract the bottle weight from the total weight to obtain:
Specific gravity requires pot cover: bottom pull169-170g/100ml surface glaze: 172- 174g/100ml color glaze:172-.
Pot body: bottom price:166-167g/100ml surface glaze:167-169g/100ml color glaze:167.
Adhesion test:
Put a piece of stainless steel with the thickness of 1mm and the length and width of 100cm× 10cm (the set weight is 50g) into the stirred glaze slurry, lift it vertically (neither fast nor slow) until the glaze slurry stops dripping, and then weigh it to reduce the weight of the stainless steel sheet.
Adhesive pot cover: bottom price:12g/10x10cm white glaze:14g/10cm colored glaze: 14g/65438.
Pot base map: 7g/10x10cm white glaze: 9g/10x10cm colored glaze: 9g/10x/0cm.
Glaze slurry aging;
It is very important that the glaze slurry should be aged for 36-48 hours before use. It can improve the working performance and operational performance of glaze slurry, but if the aging time is prolonged, it will be harmful to the performance of glaze slurry.
The retention of glaze slurry is poor, so it is necessary to add some retention agents, and the amount of retention agents should be as small as possible.
Generally, the bottom glaze is added with (nitrite+magnesium sulfate) and the top glaze is added with (potassium carbonate+magnesium sulfate). Before use, add a small amount of glaze slurry to adjust the thickness, and then add the thickened glaze slurry into the glaze slurry to avoid bubbles and affect the performance of the glaze slurry.
Third, the painting process and gestures
In order to improve the uneven glaze application of porcelain glaze powder, natural dripping operation should be adopted to achieve uniform thickness, reasonable operation and standardized operation, so as to reduce the defective rate, improve product quality, reduce the amount of glaze slurry and save costs.
1 Adjust the specific gravity and adhesion according to the product before coating, generally following the principle that the specific gravity of large products is slightly lower, the specific gravity of small products is slightly higher, and the pot cover is slightly higher than the pot body.
2 Gestures should be consistent as far as possible, generally 4-5 times at the bottom and about 2 times on both sides. Naturally, the pendulum swings.
Dip the pot body 360 degrees to the side of the pot, don't dip it to the bottom, so as not to create a horizontal bar or the bottom is too thick.
Before putting it into the drying rack, gently return it to avoid the accumulation of glaze on the edge and ears of the pot.
The manufacturing process of enamel steel plate is complicated. In the process of firing and coating, great attention is paid to the accurate grasp of gestures, which will save the aesthetics of finished products and the amount of raw materials. In addition, there will be some problems in the manufacturing process of enamel steel plates, which depends on everyone's experience in actual operation to improve their practice.

Which is better, hot-rolled pickled steel plate or enamel steel plate? Hot-rolled pickled steel plate and enamel steel plate have their own advantages and applicable occasions. The simple comparison is as follows:
1. Corrosion resistance: The surface of enameled steel plate has been specially enameled, which has good corrosion resistance. However, the surface treatment of hot-rolled pickled steel plate is different from that of enamel steel plate, so its corrosion resistance is slightly lower than that of enamel steel plate.
2. Wear resistance: The hot-rolled pickled steel plate has higher hardness and better wear resistance. Although the enamel layer on the surface of enamel steel plate has high hardness, it is fragile and easy to wear and break.
3. Aesthetic degree: the surface of enamel steel plate is smooth and bright, and the color is dazzling. However, the surface of hot-rolled pickled steel plate is rough, and it usually needs subsequent treatment to achieve a certain degree of beauty.
4. Usage: Enamel steel plate is suitable for making kitchenware, sanitary ware and other products, with smooth surface and easy cleaning. The hot-rolled pickled steel sheet is suitable for occasions such as vehicle manufacturing and machinery manufacturing that require high strength and wear resistance.
Therefore, the selection of steel plates needs to be comprehensively considered and compared according to specific purposes and requirements.
