Before we learned a simple price situation of enamel steel plate, this time, Xiaobian will take you to have a more in-depth understanding of the proction process of enamel steel plate. We mentioned that enamel steel plate is a kind of composite material, so the proction process is relatively more complex, but its material performance is good, and its appearance is also good-looking, which can be used in many different places. Then come to understand the proction process of this enamel steel plate
I. conditions of enamel steel plate
1. The carbon content is 0.08 ~ 0.12%
2. The surface structure is uniform
3. It is suitable for stretch forming, not easy to crack and wrinkle
4. It is suitable for welding, easy to clean
5. It is not easy to deform and bend ring firing. At present, the commonly used plates and models in China are Baosteel btc1, Maanshan spcc-1dc01, etc
Second, the glaze should have a wide range of firing temperature and resistance to firing, and the coefficient of thermal expansion is appropriate, After firing, it is not easy to proce cracks and deformation5. It has certain explosion-proof performance
the grinding additive and function of glaze formula
1, clay 2, quartz 3, electrolyte (nitrous borax)
the function of clay:
1 as the suspending agent of glaze, plays a suspending role
2, Clay can affect the physical structure and expansion coefficient of enamel ring sintering. Clay can change the covering power, whiteness and luster of enamel. Electrolyte: nitrite: antirust effect. Generally, 0.2-0.5% borax is used as melting aid. The standard thickness of steel plate enamel is 80-120um, The primary glaze is 120 ~ 150um
surface glaze: the surface glaze is divided into base glaze and titanium glaze
the base glaze is mainly used for color matching, the base glaze needs to have good luster and porcelain surface, glue resistance, and it is not easy to proce glue film after Decal
the white glaze needs to have good hiding power and luster, Acid resistance
the thickness of surface glaze is generally 150 ~ 200um
test index and method of glaze slurry:
1 particle size (coarse and fine) 2 specific gravity (solution weight) 3 retention (adhesion)
glaze slurry particle size test
take 50ml glaze slurry and wash it with 200 mesh screen water, After the resial porcelain powder is dried, the following results can be obtained:
standard particle size: down lead: 6-8g surface glaze: 3-5g colored glaze: 2-4G
specific gravity:
take 100ml glaze slurry into a Pycnometer (set bottle weight 50g), The total weight minus the bottle weight can be obtained as follows:
specific gravity requirements: pot cover: down lead 169-170g / 100ml surface glaze: 172-174g / 100ml colored glaze: 172-174g / 100ml
pot body: down lead 166-167g / 100ml surface glaze: 167-169g / 100ml colored glaze: 167-169g / 100ml
adhesion test:
take the plate thickness of 1mm, length and width of 100cm × 10cm stainless steel sheet (set weight as 50g) is placed in the glaze slurry after mixing, and the glaze slurry does not continue to drop until it is lifted vertically (not fast or slow). After weighing and recing the weight of stainless steel sheet, the adhesion amount is
pot cover: downward: 12g / 10 × 10cm white glaze: 14g / 10 × 10cm color glaze: 14g / 10 × 10cm
pot body downward: 7g / 10 × 10cm white glaze: 9g / 10 × 10cm color glaze: 9g / 10 × 10cm
aging of glaze slurry:
the glaze slurry needs to be aged for 36-48 hours before use, which is very important. It can improve the working properties and operating performance of glaze slurry, but if the aging time is prolonged, it will be harmful to the properties of glaze slurry, The surface glaze is generally added (potassium carbonate + magnesium sulfate). Before use, take a small amount of glaze slurry and adjust the thickness. Add the thickness adjusted glaze slurry into the glaze slurry to be adjusted, so as to avoid small bubbles and affect the performance of glaze slurry
In order to improve the unevenness of enameling powder, it is better to adopt natural dripping operation, so as to achieve uniform thickness, rationalization of action, standardization of operation, and save physical strength, so as to rece the defect rate, improve proct quality, rece the amount of glaze slurry, and save cost, Generally follow the principle that the proportion of large procts is slightly lower, the proportion of small procts is slightly higher, and the cover is slightly higher than the pot body2 gesture should be consistent as far as possible, the bottom should be swung 4-5 times, and the two sides should be swung about 2 times, and the force should be subject to the swing of the penlum.
3 when soaking the pot body, it should be 360 degrees to the edge of the pot, not to the bottom, so as to avoid the horizontal bar or too thick bottom, The manufacturing process of enamel steel plate is relatively complex, so we pay attention to the accuracy of hand gestures in the process of firing and enamelling. The accuracy of hand gestures can save the beauty of the finished proct and the amount of raw materials. In addition, in the manufacturing process of enamel steel plate will encounter some more difficult to solve problems, these problems depend on everyone's experience in the actual operation to improve his practice

According to the statistics of blockbeats, as of July 9, more than 30000 websites in the whole network have built-in "mining" codes. As long as users open the website for browsing and operation, the website will call the computing resources of computers or mobile phones to "mine"
if you have the habit of browsing "yellow" websites, you should also pay attention to it, because many "yellow" websites will add "mining" code in the future to increase revenue.
