Description

Artificial marble raw material supply device and supply method {APPARATUS AND METHOD FOR SUPPLYING LIQUID RAW MATERIAL OF SCAGLIOLA}

The present invention relates to an artificial marble raw material supply device and a supply method, and more specifically, to separate each composition in a plurality of divided storage space, and to deliver the same pressure to a plurality of raw material storage tank at the same time the relative discharge between the composition To maintain the mixing ratio.

Natural marble, which is formed by recrystallization after lime or dolomite is subjected to contact or wide-area metamorphism, is used as interior and exterior materials of buildings due to its characteristic multicolored pattern and luster.

However, natural marble has a problem that its use is limited because its thickness is usually 10 mm or more and its volume and weight are not easy to handle and process and the price is high.

Therefore, recently, artificial marble, which has the appearance of natural marble and has a low volume, weight, and price, has been widely used in each field.

Artificial marble is divided into two types, acrylic and unsaturated polyester, by the base resin used.

In general, artificial marble made of acrylic resin is widely used as a counter table and various interior materials due to the advantages of a beautiful appearance and excellent workability, and light and excellent strength compared to natural marble.

In addition, unsaturated polyester artificial marble has a disadvantage in that weatherability and heat resistance are poorer than acrylic artificial marble and are difficult to thermoform.However, since the refractive index is similar to that of aluminum hydroxide, which is used as a filler, the transparency of the polymer is natural, so that it is more natural and deeper. There is an advantage that can realize a sense of appearance. Such artificial marble is recently used in various applications such as various top plate materials, dressing tables, wash basins, tables, wall materials, flooring materials, furniture, interior materials, indirect lighting panels, interior accessories.

The manufacturing method of acrylic and unsaturated polyester-based artificial marble is generally methyl methacrylate (MMA) used as a monomer (monomer) and high molecular weight poly methacrylate (PMMA) or unsaturated polyester. (Unsaturated polyesters: UPE) is a syrup mixed with an inorganic filler having a specific gravity such as aluminum hydroxide, calcium carbonate, silica, or silicon, as a main component, and thus an initiator, a crosslinking agent, a chain transfer agent, and a coupling agent. After mixing the additives such as pigments and the like to mold and harden in a molding die or continuous steel belt to manufacture.

Conventional artificial marble was used after the process of mixing the main material and auxiliary material in the production of the raw material, and then put them in one container.

At this time, in consideration of the defective rate of the product to produce a raw material by measuring the excess amount together, if the defective rate is higher than the predicted value, each raw material had to go through the process of re- weighing and reproducing.

In addition, even if the raw material mixed with the defect rate is lower than the predicted value remains, the mixed raw material including the main material, the filler, the curing agent, the additive, and the various pigments must be exhausted within 1 to 2 hours, and thus the remaining raw material cannot be stored for a long time. The raw materials also had to be disposed of.

In addition, the container mixed with the raw materials had to be reused after washing the inside using a detergent such as acetone after use, and the time and the amount of the detergent used during the washing process acted as a problem of lowering productivity.

Therefore, the present invention has been made to solve the above-mentioned problems of the prior art, the respective compositions used in the manufacture of artificial marble are separately accommodated in a plurality of raw material storage space, the plurality of raw material storage space through the actuator It is an object of the present invention to provide an artificial marble raw material supply apparatus and a supply method for maintaining a constant discharge rate and the mixing ratio between compositions by simultaneously delivering the same pressure.

As a technical means for achieving the above object, the present invention includes a main material storage tank in which the main material used for the manufacture of artificial marble is stored; At least one submaterial storage tank in which submaterials used for manufacturing artificial marble are stored; An actuator for receiving a piston in the main material storage tank and the submaterial storage tank, respectively, and for transmitting a constant pressure to the plurality of pistons; In order to provide a pipeline with a hollow inside so that the raw material can be moved, it is formed in each of the discharge pipe and connected to each discharge pipe connected from the discharge end of the main material storage tank and the subsidiary material storage tank to control the supply amount of the raw material according to the degree of opening and closing Characterized in that it comprises a; discharge control valve that can be.

In addition, each composition used in the manufacture of artificial marble is separately accommodated in a plurality of raw material storage space, each side of each raw material storage space by transmitting the same pressure through the actuator simultaneously, Together, it is characterized in that the mixing ratio between the relative compositions is kept constant.

According to the artificial marble raw material supply apparatus and the supply method according to the present invention, it is possible to predict the amount of production each time the artificial marble is manufactured to solve the inconvenience of measuring and using each raw material.

In addition, there is an effect that solved the problem of having to re-weigh the raw material due to the shortage of the weighed raw material, or to discard the remaining raw material due to the excess of the weighed raw material.

In addition, since the raw material storage tank is classified according to each composition, it does not need to be washed every time after use, and the remaining raw materials are inherent rather than mixed, so they can be reused later and used as needed. There is also.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
