Gold Asian Ceramic Zhuoyuan Ceramics

1. What is ceramic?

Ceramics are hard materials that are formed by appropriate proportioning, pulverizing, shaping and processing of clay raw materials, inert raw materials and flux raw materials through a series of physical and chemical reactions under high-temperature roasting conditions.

2. What is the difference between pottery and porcelain?

The difference is in water absorption. The water absorption is less than 0.5% for porcelain, more than 10% for pottery, and halfway between the two.

3. Which bricks are porcelain in daily life? Which is ceramic?

We commonly use a variety of polished tiles, unglazed mosaic tiles, most sanitary ware is porcelain, water absorption E ≤ 0.5%, antique tiles, small floor tiles (wall climbing), crystal tiles, wear-resistant bricks, matt bricks, etc. It is an enamel brick, ie half-tile, with a water absorption of 0.5% to 10%.

4, what is the water absorption rate?

The water absorption is the percentage of the product that is absorbed by the pores in the ceramic product.

5. How are ceramic tiles classified?

Divided into inner wall tiles, outer wall tiles and floor tiles by purpose.

Divided by material: Porcelain tile - good light transmission, delicate cross-section was shell-like; semi-porcelain brick - poor light transmission, high mechanical strength, cross-section was stone; ceramic brick - opaque, mechanical Low strength, rough section; according to the forming method is divided into dry pressing method, plastic method, grouting method.

6, What are the varieties of ceramic wall tiles?

Glazed Interior Wall Tiles: Tiles, Flower Patches, Waist Lines; Ceramic Exterior Wall Tiles: Color Glazed Tiles, Unglazed Tiles, Wool Face Tiles, Mosaic Tiles; Ceramic Floor Tiles: Porcelain Tiles, Color Glazed Tiles, Peeling Tiles, Red Floor tiles, mosaic tiles, square tiles, step bricks, etc.

7. What is the difference between polished tiles and glass fossils?

There are many kinds of polished tiles on the market, such as planed bricks, whole bricks, vitrified tiles, and complete glass fossils. Bolivian fossils are also known as polished tiles. They are popularly called on the market and are professionally called “polished porcelain”. brick".

8, wall tiles can be spread on the bathroom floor?

Wall tiles (ceramic tiles) are generally not paved on the ground. Because the ceramic tile is ceramic, its mechanical strength is low, and it is easily damaged by pressure when it is laid on the ground. The toilet floor is wet for a long time, and the tiles are prone to moisture expansion and rupture. In addition, the glazed tiles are not slippery.

9. What are the differences between premium products and primary products (qualified products)?

Premium products and first-class products are all qualified products. Products that can be used normally have no effect on their functions. Mainly reflected in the appearance of the quality and deformation of the allowable range is different, such as surface spots, pinholes and so on.

10, excellent products have no defects?

Since ceramic products are products of various raw materials that have been fired at high temperatures, imperfections, deformation, and other defects cannot be completely avoided, and national standards also allow certain degrees of defects to exist. Such as the surface quality, polished tiles and other fine products require that at least 95% of the bricks are 0.8m away from the vertical observation surface without defects.

11. Is the brick made from underground mud?

The main raw materials for the production of wall and floor tiles are: kaolin and chemical materials. Kaolin mainly includes sand, stone powder, black mud and white mud, etc. The chemical materials mainly include coloring materials, water reducing agents and so on. The popular saying is that bricks are made of mud, but it is not ordinary mud. To achieve a certain chemical composition, quality and stability can become the ideal raw material.

12, red brick is ceramic brick, white brick is a porcelain brick, red brick is not as white brick it?

This argument is unscientific. The color of the green body that determines the color of the blank is the content of iron and titanium oxide in the raw material of the blank. The higher the content, the darker the color appears after firing. It only determines the color of the blank and will not affect the quality of the brick. The main factor affecting the internal quality of bricks is the degree of sintering. Good quality bricks are truly “burned” bricks.

13、Why the polishing tile be waxed or coated with antifouling agent?

Polishing bricks can better protect the bricks, avoid the impact of external objects and friction during construction; after the wax is removed, the gloss of the bricks can be increased; more importantly, the pores of the brick surface can be filled so that the dirt will not be stuffed. Within the stomata, it is easy to clean daily.

14. Why do you choose dry hanging when polishing the tiles on the exterior wall?

Mainly security considerations. Polished bricks have low water absorption and smooth back surface. They are not easy to stick with cement mortar. In addition, polished bricks are heavy and easy to drop.

15. What kind of anti-slip effect is better for matt bricks and crystal tiles?

Matte bricks have a better anti-slip effect because matt bricks generally have a non-slip design.

16, polished tiles, matt bricks, crystal tiles which slip better? why?

The anti-skid effect of the polished tiles is best because the polishing effect of the tile after polishing is stronger

More info about PCR Tubes:

What Are PCR Tubes?

PCR tubes are small tubes made of high-quality virgin polypropylene with a conical bottom. They have uniform thin walls to facilitate efficient heat transfer to the sample. These tubes are autoclavable and work well with most thermal cyclers.

What Are the Applications of PCR Tubes?

The most common application of PCR tubes includes various molecular biology biochemistry experiments requiring real-time PCR (Polymerase Chain Reaction). As these tubes have ultra-thin walls, they are perfect for accurate and steady thermal transfer in an array of thermocyclers. Our thin-wall PCR tubes meet the protocols required for PCR, qPCR, reverse transcriptions, and a variety of other applications.
