Description

Ceramic grouting product of porcelain colored granular carcass and its manufacturing process

The invention relates to a daily-use porcelain, sanitary ceramics and craft ceramic products and manufacturing processes, such as wash basins, toilets and advanced daily use, which have the characteristics of porcelain granite patterns, and adopts a suction filter mold grouting or die-casting process. Porcelain such as tableware, tea set, wine set, bottle, can and other handicrafts, etc., especially relates to a new type of decorative die-casting and grouting technology of ceramic colored granules, and ceramic grouting products and its manufacturing process.

In the prior art, ceramic products of the suction filtration mold grouting or die-casting process are sanitary wares and daily-use porcelains with porcelain white ceramic embryo structure, such as wash basins, toilets, tableware, and the like. On its surface, various single-color decorative glazes such as red, blue, green, white, gray, and beige are used. Its color tone is single. For example, when the monochrome wash basin is matched with high-grade marble or granite countertops, it does not look very coordinated, and it cannot make the bathroom vanity and dressing table appear better decorative effects. Pigment-colored sanitary ware and daily-use porcelain use the decal process, which can only paste some gold or other colored pattern lace on the periphery of the circle, but it cannot decal paper in a large area in a three-dimensional state, so it is also very monotonous. For example, this kind of toilet is not very coordinated when it is matched with the bathroom and high-grade marble or granite floor and wall. The three types are the existing silk screen printing technology of tableware, tea set, etc. Different patterns can be formed, but the existing process can generally only be color-printed on a flat surface, and some screen printing processes can only be printed on the small edges of daily products such as cups. Three-dimensional screen printing technology or products for large-area three-dimensional orientation on large objects such as sanitary ware or vases; four kinds of techniques for making three-dimensional porcelain granite and marble disclosed by the inventors, the middle process is: According to the required pattern, a corresponding consistent mold die is made, and the die is in communication with the container containing the raw materials of the products of different colors. This mold is the core of this process, but because of the structure of the rear part of the mold in this method, Too simple. When you need to make complex multi-color patterns with up to several hundred color block areas, the raw material container behind the die mouth will be too large. Sufficient space can complete the requirements of fine and complex color patterns, and there are obvious defects. In particular, there is no way to complete the complex color pattern implementation process of three-dimensional three-dimensional space such as sanitary ware. Five types are used in sanitary ware or daily use. In the spray-painting process on porcelain, this process pattern is relatively rough. When multiple colors overlap, a four-convex shape appears on the surface of the product, making it not smooth and flat. If there are too few sprays, leakage will occur again. And this process is impossible to produce a large area of the overall color of the special-shaped ceramic products surface decoration; six kinds of ceramic color pattern products and manufacturing methods and colorful carcass high temperature under-glaze color sanitary ware ceramic products and manufacturing methods thereof ; The pattern of its product is line-shaped, because the common point in its processing method is that different colored pastes are injected into the product from one hole at the same time. In the mold cavity, the pattern of the product gradually expands from a linear shape from the injection port to a radial shape, and the pattern gradually expands from a very small linear shape of the injection port until the mold closed area gradually spreads. The block shape from the line shape to the closed area is connected end to end, which limits the above two prior art features. The ceramic color pattern products and their manufacturing methods also talk about different processes using pressure, speed, and time difference, but the subsequent color paste parts are also connected end to end. The main thing is that in the production of all grouting products, such as porcelain, sanitary porcelain, and craft porcelain, the current process has not shaken off the concept of injecting different color paste from the grouting holes of the traditional grouting process. Therefore, the products of the existing multi-color grouting process cannot be truly made like marble and granite in the process, and can not appear in dots or lumps, and cannot be made intentionally according to the stone pattern. Therefore, its existing processes and methods cannot truly produce ceramic products with grouting technology that can imitate natural marble and granite. This is also the fundamental reason for the fact that the daily porcelain, sanitary porcelain, and craft porcelain of the theoretical color matrix grouting process in the ceramic market have not been able to compete, so that the product is basically absent. Although the relevant technology materials and publicity materials describe the prior art as making the product patterns natural, landscape patterns, wood grains, snake patterns, heart-shaped patterns, wave patterns, stone patterns, and landscape-like paintings, stone plates, cloud pictures, etc. Patterns are only abstract descriptions. Because patterns cannot be produced in a controlled manner, it is impossible to form controllable, real natural marble, granite patterns, significant, definable, expressible substantive content. Products with novel characteristics; seven kinds of mud colored grains in the ceramic granite product and the granule processing method described in the manufacturing method thereof, the colored muds with the indicated moisture content of 6-15% The materials are made with different sieve holes. Particles of different colors are mixed into the mold and semi-wet or semi-dry pressed. The particles with high moisture content are semi-wet pressed. The particles with low moisture content are semi-dry. Compression molding is also mixed in the process → pressing molding → scraping-drying → firing-glaze firing-products, and some are mixing-pressing molding-scraping → firing → research Mill → product. It can be seen that the particle processing in its process method is only suitable for general compressible ceramic products, which is consistent with the existing process of large particle vitrified bricks, and this process is not suitable for the grouting and filtration mold process. It can only be processed on flat products such as decorative materials, and its surface will not be very smooth, at least it will not be as smooth as the product of the grouting process. Therefore, in the method described, there is also a process that requires grinding and polishing. In this document, for products made by the grouting process of suction filtration, the process is only described as injecting different color mud slurry into the suction filtration mold, and there is no description of injecting granular color material into the suction filtration mold. It can be seen that when comparing the two processes in this document, the author's granulation process is limited to simple flat surfaces that are dry-pressed and wet-dried and need to be polished.

In short, the existing suction filtration molds, sanitary ware with grouting technology, daily-use porcelain, and craft porcelain products, due to the various defects of the prior art, have not appeared in any of the complex geometric structural products that can produce natural flowers. The overall effect of the granite pattern. Summary of the invention The main purpose of the present invention is to overcome the defects existing in the ceramic products of the prior art grouting process, and provide a ceramic grouting product with a new structure of a porcelain colored granular carcass and a manufacturing process thereof, so that Large areas or 100% complete granite grain patterns appear on the carcass and decorative surface. The three-dimensional sculpture art of the products of the present invention, such as sanitary porcelain, daily-use porcelain, craft porcelain, etc., is carved from a single piece of natural marble or granite or jade, and processed through complex polishing of multi-dimensional surfaces. The product is exquisite; when it is inlaid with natural granite bathroom vanity countertops of the same color and pattern, it will be integrated into one, the overall sense will be greatly increased, and it will be extraordinarily gorgeous; like the product of the present invention, such as a toilet, It is as delicate as a three-dimensional sculpture artwork treated with a whole piece of natural granite and complex polishing of the multi-dimensional surface after engraving. When placed on natural granite or marble walls and floors of similar colors and patterns, When decorated, the entire bathroom will be as beautiful and luxurious as the Palace of Fine Arts. Another example is that the products of the invention such as bowls, basins, cups, saucers, etc. in tableware, tea sets, etc. will be as exquisite and luxurious as those made of natural stone, including jade sculptures.

Another object of the present invention is to overcome the shortcomings of the prior art suction filtration mold grouting process, so that the production process of the grouting process has a fundamental change, so that it is in the carcass and the surface of the carcass, as if the monolithic Natural granite or jade is as fine as three-dimensional sculpture artwork after complex processing such as multi-dimensional surface polishing after carving. Especially in the tableware, tea sets and wine sets of fine and small daily necessities, if animal bone meal or substitute ingredients are added, and other auxiliary processes are added, the products will be made like natural granite or jade fine carving and polished court art. Products, so that the quality and effect of grouting daily porcelain has a fundamental change, and has a feasible process basis for more casual art production.

The object of the present invention is achieved by the following technical solutions. According to the present invention, a ceramic grouting product of a porcelain colored granular carcass, which includes jade porcelain, sanitary ceramics, and craft ceramics using a suction filter mold grouting or die-casting process, is characterized in that: Particles having two or more colors with a diameter ranging from 1 to 50 mm and ranging from 50 to 50 million particles.

(1) Preparation of colored particles:

First, according to the preparation method of slurry injection that is well known to those skilled in the art, a variety of ceramic raw materials, pigments, and colorants suitable for the slurry injection process are formulated, and after grinding, mixing, and then removing iron. Prepare four kinds of pastes: pale red, gray, brown-red, and fuchsia, and stale for use.

Then, the spray fine powder molding process used to produce vitrified bricks is used to make it into four different color powder particles;

Then use a 1,600-ton brick press to adjust the pressure strength to 100-500 bar, and press the three powders of gray, brown-red, and fuchsia into bricks with good strength;

It is pulverized by a pulverizer, so that after the gray sieving, large particles with a diameter of 1 to 5 mm are left, and brown red and magenta leaves with large particles with a diameter of 3 to 10 hidden;

Then back up 30% of the large brown particles, 40% of the large fuchsia particles, and 15% of the large gray particles.

Then make a water-soluble viscose solution, roll-wrap the above three particles, and dry, so that a layer of water-soluble viscose component is attached to the surface;

Then back up the light red powder by 15% and mix with the colored particles of the above proportion for future use.

(B), die-casting embryo body:

The above-mentioned four types of granules and powders are mixed into a plastic suction filter mold of a wash basin using a rotary die casting process. After the mold is filled, the pressure is gradually increased and the pressure is maintained.

Then, through the die-casting inlet, the mud water with a very low concentration of light red powder is gradually poured into the particles in the wash basin suction filtration molding mold frame, so that it gradually fills the fine gaps of each particle. Due to the high density of large particles, Therefore, the particles of each color can only be gradually immersed in water, and the water-soluble glue on the surface layer is gradually dissolved to form a granular slurry. At this time, the vacuum suction filtration system is quickly turned on, so that the particle slurry water in the suction filtration mold and part of the water-soluble adhesive are removed from the microporous plastic mold wall, and the mold is released after the pressure is maintained. At this time, the dried embryos were obtained in which granules of various colors were tightly combined with each other, with high strength and smooth decorative surfaces.

After refurbishing, punching, scraping the embryo, and applying a transparent glaze after the drying process.

(3) Enter the firing process, and obtain the product after firing.

The product of this embodiment has the same effect as natural granite purple color hemp. Due to the combination of natural red, brown, red, gray particles and pale red areas with different sizes of natural stones, the surface is smooth and flat, like natural granite purple color hemp carving, fine polishing and polishing.

The second embodiment of the present invention is as follows:

The implementation process is divided into four stages: preparation of colored granules; preparation of slurry; molding of product embryos; firing and firing.

(1) Preparation of colored particles:

First, according to the slurry preparation process slurry preparation methods that are well known to those skilled in the art, a variety of ceramic raw materials, pigments, and colorants suitable for the grouting process are formulated, and after grinding and mixing, the iron is removed. After that, a pale red color was prepared. gray. There are four kinds of brown-red and fuchsia pastes. Separately stale.

Then, the spraying process of vitrified brick is adopted to make it into four different color powder particles; under the condition of using a 1600-ton brick press to adjust the pressure intensity to 100-500 bar, the gray, brown red, and purple The three red powders are pressed into bricks with good strength, and then crushed by the grinder to make the gray sieved leave large particles with a diameter of 1-5 hidden, and the magenta and magenta leaves with a diameter of 3-1 0 Back up large particles, however, back up 30% of large brown particles, 40% of large fuchsia particles, and 15% of large gray particles; then prepare the above three color particles for freezing and freeze them to Celsius Below zero, its water-containing portion becomes ice-like, the purpose is to make the particles have a time to maintain the shape of the particles when the slurry is mixed with water, and the frozen particles gradually become melted particles.

(II) Slurry preparation: Mix the light red powder with 5% and 95% moisture into the grouting process for future use.

(III) Molding embryo body by grouting process:

Prepare the reddish slurry, quickly mix the other three colored particles of frozen material into the slurry, and use the medium pressure or high pressure paddle injection process to quickly inject the mixture into the prepared plastic wash-filtration mold for the wash basin. Holding pressure.

When all the frozen hard particles of the colored granules are in the state of mud-like particles, quickly turn on the vacuum pumping system, so that the water in the particle slurry in the suction filter is removed from the micro-porous plastic mold wall. Demolding. At this time, a dried embryo body with tightly combined granules of various colors, high strength, and smooth decorative surfaces was obtained.

After refurbishing, drilling, scraping, and applying transparent glaze after drying. (4) Enter the firing process, and obtain the product after firing.
