When pouring the glue liquid into the spray gun pot, add oil or edible oil as soon as possible to float a layer of oil film with a thickness of 1-2mm [...]

Classification of ceramics(1)

The blank of semi porcelain is close to that of porcelain, but it still has 3-5% water absorption after firing (true porcelain, water absorption is below 0.5%), so its performance is not as good as that of porcelain, which is better than that of fine ceramics. Porcelain is a higher stage in the development of ceramics. It is characterized by complete sintering and vitrification of the body, so it is very dense, and has no permeability to liquid and gas. [...]

Classification of ceramics

The difference between pottery and porcelain lies in the difference of material soil and temperature. On the basis of the temperature of pottery making, adding fire and heating, pottery becomes porcelain. The firing temperature of pottery is 800-1000 ℃, and that of porcelain is 1300-1400 ℃. There are many kinds of ceramic products, the chemical composition between them. Mineral composition, physical properties, and manufacturing methods are often close to each other without obvious boundaries, but there are great differences [...]

Characteristics of ceramics

When it comes to ceramic materials, it’s hard to avoid separating ceramics from porcelain. We often refer to ceramics as pottery and porcelain A combination of two types of utensils. In the field of creation, pottery and porcelain are indispensable parts of ceramic art, but they are different in quality.Ceramic material: compared with porcelain, the ceramic is relatively loose in texture and coarse in grain. The firing temperature is generally between 900 ℃ – 1500 ℃, and the temperature is [...]

Corrugated paper

Corrugating paper is a kind of board-shaped material which is made of corrugated paper and corrugated paper. It is generally divided into single corrugated board and double corrugated board. According to the size of corrugating, it can be divided into five types: A, B, C, E and F. The invention and application of corrugated paper has a history of more than 100 years. It has the advantages of low cost, light weight, easy processing, high strength, good printing adaptability, convenient [...]

Tinplate printing has special requirements for ink(1)

(1) drying process of ink In tinplate printing production, ink drying is a complex physical and chemical reaction process. It is necessary to control the drying speed of ink reasonably and master the physical and chemical mechanism of ink drying, so as to effectively carry out rapid printing operation and ensure product quality. Too fast drying of the ink will reduce the normal transmission performance of the ink and affect the normal operation of the production; it will result in [...]
