Feasibility study on high temperature porcelain image technology

The image technology of high temperature porcelain is developed with reference to foreign scientific research results and combined with the principle of four-color overprint. It uses a computer to control the imaging system. Firstly, the pictures are input into the computer through the scanner, and the program is compiled after image design and modification. Then put the porcelain into an imaging machine to print and image directly, and then fire it at 800 degrees. No plate making is needed, and auto production line operation is realized in the whole process. The finished product is resistant to scraper, water immersion, fire burning and purple lining. Indoor and outdoor waterproof and colorfast. The high-temperature tombstone porcelain system is mainly used in the funeral industry, such as making spirit tablets, tombstones and portraits. , can also be used to make other porcelain crafts.

At present, the domestic high-temperature porcelain market is blooming everywhere, and the technical equipment tends to be homogenized seriously. Due to the limitation of the equipment itself and the ink company, the exposed problems are often similar, such as thick ink dots, low resolution and easy plugging. Compared with other similar technical equipment, Italian high-temperature porcelain statues have the following obvious advantages:

First, it breaks through the limitation of flat plate and can be made on porcelain of any shape.

Second, the unique high-temperature ink formula and advanced ink box modification scheme ensure smooth printing. Not easy to block, high success rate.

Third, the application of scientific positioning device is accurate, and the success rate is 98%. The definition is as high as 2400DPI, the ink dots are delicate, the colors are exquisite and natural, and the three-dimensional effect is strong, achieving the effect of taking pictures.

Investment analysis:

With the reform of urban and rural funeral system and the acceleration of aging process in China, as an unpopular technology, the processing and production of porcelain statues has an extremely broad market space and considerable profits. The cost of making a 4-inch colored tombstone porcelain statue is only 50 cents (excluding porcelain plates), but the market price is above 60- 120 yuan. In the choice of investment projects, the phenomenon of "unpopular but not hot" is not uncommon. Investing in "speculation" is good at capturing business opportunities that others cannot see, and it is easier to shake hands with wealth.

Attachment: Super thermal transfer coating material that can partially replace the four-hit-one-burn process.

Brief introduction of super thermal transfer coating

Early thermal transfer coatings mainly used thermosetting acrylic resin, amino resin, epoxy resin or silicone resin, polyester, polyurethane and other modified compounds.

It has been used for more than twenty years. With the development of materials science and technology, after long-term experiments, we have adopted two kinds of materials with the best performance in the world.

Two kinds of resin materials: silicone and PTFE (also known as Teflon, PTFE, PTFE, F4, Plastic King), synthesized a new generation of fluorosilicone modification.

Thermal transfer coating. Silicon is the most abundant element on the earth, one of the basic substances for the origin of life, and one of the substances that meet the hygiene standards best. Tetrafluorone is modern.

A kind of resin plastic with the most stable chemical properties, which has strong corrosion resistance and weather resistance. Tetrafluoride spraying is widely used in many products, such as hot plate of bronzing machine, electric iron, perm clip, non-stick pan and so on. But the spraying process is complicated,

One is to make the material into powder, disperse it in water for spraying, melt and sinter the powder on the surface of the sprayed object at a high temperature above 350℃, and then spray it.

The leveling time is not enough, so the surface treatment effect obtained by this method is rough (such as the inner container of rice cooker). Another way is to put the material

The material is melted into liquid at a high temperature of about 400℃ and sprayed on the surface of the metal plate by thermal spraying. This method should be used in large flat hot stamping machine industry.

Widely used, the surface of the treated heating plate is flat, self-cleaning and non-sticky, and it is no longer necessary to isolate it from the cloth with high temperature cloth. The physical state of the super thermal transfer coating resin we synthesized is viscous liquid, and no solvent needs to be added. Direct spraying with a special spray gun has the following characteristics.

Excellent leveling property, it can be completely cured by baking at 200℃, and the gloss and pattern reduction of the cured coating are excellent, which is almost the same as that of ordinary heat.

The difference of transfer coating is as follows:

First, it can be washed repeatedly with a dishwasher for a long time, and the image does not fade, and the edge of the pattern is clear and does not disperse;

Second, the ingredients fully meet the FDA standards in California, USA, and can be used for tableware plates, which can directly hold food.

Third, the heat fastness is excellent, even if the picture has just been transferred at 200℃ and has not cooled down, it can't be moved with nails; When hot water is washed, it collides with each other, and the coating will not be damaged.

4. In the process of transfer printing, the thermal sublimation ink can cross-link with the coating to generate new substances, and the pigment can be firmly fixed on the coating, even if it is heated again,

Ink will not spread to the untransferred area; This property can be transferred on the same image cup or other objects made of this material twice or more at will.

The photos you need.

5. The non-diffusion characteristics of transfer printing can be applied to all daily-use ceramics, just change the pigment of ceramic decal paper from high-temperature ceramic pigment to thermal transfer printing.

Ink can be used, and the decal method is the same as the traditional method, except that the baking temperature is reduced from 800 degrees to 200 degrees, which saves a lot of energy and improves the picture clarity.

Six, normal weather resistance for 50 years, resistant to pressure cooker cooking or high-pressure steam for a long time, the coating does not fade. Other applications: stainless steel tableware, knives, bathrooms.
