After fifteen years of spring and autumn, Foshan ushered in the 30th Foshan Ceramics Fair. With the smooth start of the exhibition, the trend products have also unveiled the mystery, one by one in the view of the exhibitors.
As a reporter for professional media, the reporter focused on the new technologies and processes that appeared at the show. We can see which technology changes and process innovations through the products? And listen to the reporter one by one.
Not too much. On the basis of the existing exaggeration: At this time, the general trend, can be compared to the world’s world, to a certain extent, there is a lot of “the world.”
Supporting the general trend of dry and wet mixing. Whether it is dry or wet, there is only one purpose. Working on the green body of the tile, extending the innovation from the surface of the tile to the blank is one of the performances of the product.
Specifically, dry mixing is a process in which a powder is mixed into a desired coloring material during granulation to uniformly adhere the coloring material to the surface of the green body particles to form a coloring process. This process is still white because there is no color inside the green colorant particles, so there will be white spots in the color of the green body when the brick body is cut sideways. Some people think that this is a defect of color saturation, but some people think that it can moderately increase the visual jump and liveliness.
Wet mixing, the coloring material and the green body powder are thoroughly mixed and colored before granulation. Therefore, each of the granules produced is uniformly colored from the inside to the outside. The color is more evenly saturated. However, the wet color mixing also has the disadvantage that the process is more complicated than the dry method.
The reporter observed at the exhibition that most of the whole-body bricks introduced at this exhibition were produced by dry-mixing process, and only a few individual bodies were wet-processed (except for solid-colored whole-body bricks).
Large plate tides supported by large tonnage presses, ultra-wide-width polishing and inkjet technology
Ceramic slabs are often quite impressive during the exhibition due to their oversized specifications. Ornamental, looking at it, at a glance. At this year’s Ceramic Fair, the heat of ceramic slabs continued to rise. The size of the exhibition was 900× 1800mm was the mainstream, 1500× 3000mm, 1200× 2400mm, 1500× 3000mm or even larger. The technical support behind it is mainly in the molding technology & mdash; — large tonnage press, veneer technology & mdash; & mdash; wide inkjet equipment, large glazing equipment and deep processing technology & mdash; & mdash; wide-width polishing equipment field.
Among them, in terms of molding technology, it is roughly divided into two horizontal directions of foreign and domestic vertical, while the horizontal type is divided into rolling forming and extrusion molding equipment; Mainly in stamping.
Rolling and extrusion, theoretically, it is possible to produce larger slab specifications. Therefore, we see that ceramic slabs with a width of more than 4 meters are common in foreign countries. Most of the products on display are imported or purchased from foreign equipment. The stamping and forming presses are mainly produced by the large-tonnage presses that Henglitai and Kodak have launched, such as the 1680-ton press, which can meet the production requirements of 1200× 2400mm products.
In terms of finishing technology, one is the support of ultra-wide-format inkjet devices, and the other is the emergence of large-scale glazing equipment.
The reporter was informed that at the ceramics industry exhibition at the end of June this year, MEGA has launched an ultra-wide-format inkjet device that can print more than 1600mm wide-format printing and match the production requirements of ceramic slabs. At the same time, this month’s ultra-wide-format inkjet equipment has been produced in Hangzhou Nobel’s production of ceramic slabs, with a maximum inkjet width of 2000mm. Other brands of inkjet devices have also introduced ultra-wide-format devices.
In terms of large-scale glazing equipment, cabinet-type fuel injectors and linear glazes all have glaze equipment that meets the needs of ceramic slabs.
Third, the field of deep processing, mainly the technological advancement of polishing equipment to support the demand for ceramic slabs. Due to the larger size, it is necessary to increase the polishing area per unit time, and it is difficult to complete the polishing process in order to ensure the constant line speed. For this reason, the polishing equipment has also been greatly improved this year, and the production efficiency of ceramic large plates has been met by the improvement of polishing efficiency and polishing precision.
Continued upgrade of inkjet machine brings more realistic technology
At this exhibition, the color and texture of the tile surface are further moving towards real life, with tiles resembling stone texture. It can be seen that more surface irregularities are realized, and the cracks formed by natural stone are all displayed, which is also a highlight.
Behind this highlight, it is not unrelated to the upgrade of inkjet devices and the development of matching inks. Among them, in terms of inkjet equipment, the first is to continuously upgrade the equipment used for glazed tiles; the second is to achieve cross-border, applied to polished tiles to achieve inkjet oozing process.
On the glazed tiles, there are mainly channels or devices for printing functional inks, such as ink grooves, peeling inks, and inkjet printing channels. And “glue + dry grain process” is by adding a special inkjetPrinting glue equipment to achieve. In addition, the combination of throwing bricks and ordinary bricks is also one of the highlights. The process of supporting it mainly requires inkjet printing to realize the function of spraying gold water. Therefore, inkjet equipment for spraying gold water is also allowed.
Traditional inkjet printing is commonly used on glazed tiles, but today, the output of inkjet etched polished tiles has broken the boundaries of inkjet applications and crossed the boundaries of polished tiles. The inkjet printing ink is applied to the micropowder layer to realize the texture of the micropowder layer, and the richness and level of the polished tile texture are once again increased.
Grinding blocks and glazed innovations support the change in brightness of brick surfaces
Another craze at the show was the display of a multi-faceted, different brick-faced brightness product, including traditional mirrors. Recently, the soft surface of the hot and the matt surface products that have not returned to the heat before. The brightness of the supporting tile surface is more abundant in the polishing process and glazed products.
From the mirror to the soft light and even the matt, the key point is that the polishing block changes, and the grinding force used is different. The need for grinding of the mirror surface is large, the grinding block is required to be harder and the cutting force is stronger; the soft light is relatively softer, and new demands are placed on the grinding block.
Furthermore, due to the matt and soft-light products, the surface has higher anti-fouling performance than the mirror-finished products. Therefore, the opposite glaze has higher anti-fouling performance requirements. An upgraded version of the glaze supports the birth of these products.
Functional inks lead the functional tile to hot return
Functional tiles are hot at the show, “The functionality has two directions. First, the addition of ceramic tiles is new in addition to decoration. Function; second, the upgrade of the tile surface decoration function.
The first category of products is a batch of ceramic tiles similar to negative ions, anti-fouling self-cleaning tiles, anti-slip functional tiles and so on. Among them, at this year’s Ceramic Expo, the more prominent is the rise of negative ion ceramic tiles. Many enterprises have put a large number of instruments for testing negative ions in the booth. The straight tube displays the negative ion function of the ceramic tile to attract customers. Stop and observe. The support of this product is mainly due to the negative ion ink or negative ion glaze.
The second is mainly the re-decoration function of the tile surface, such as ink, peeling ink, fine ink and glue + dry grain technology. The main function of these functional inks is to create a textured texture on the surface of the tile, making the tile pattern more realistic and closer to the realistic effect of counterfeiting the natural stone texture. As mentioned earlier, the application of these functional inks requires an upgrade of the inkjet device.
It is because of the advancement of technology that the product is colorful. When you watch the Taobao meeting, look at the technology behind the product from another angle, which justifies the results of technological innovation. In short, a thousand people look at Hamlet, there are a thousand Hamlet in the center of the eye. What the reporters see is what you see?
