The monitoring unit 500 checks the driving state of the flywheel 200 and the swing jaw 300 in real time and displays driving information of the flywheel 200 and the swing jaw 300. [

3, the monitoring unit 500 may include a case unit 510, a protective sheet unit 520, a display unit 530, and a control unit 540.

The case part 510 protects a circuit such as the control part 540 installed in the internal space and is provided with a display part 530 on the front side and a protective sheet part 520 on the entire surface except for the part where the display part 530 is installed And is inserted into the mounting groove 110 formed in the main body 100.

110 to 130 parts by weight of high-density polyethylene resin (HDPE), 170 to 190 parts by weight of talc, 1 to 10 parts by weight of germanium powder 15 to 25 parts by weight of glass fiber reinforced plastic, 2 to 7 parts by weight of glue, 5 to 10 parts by weight of cork powder, 1 to 4 parts by weight of sucrose (C12H22O11) powder, 2 to 5 parts by weight of boehmite, (OH)), and having a specific gravity of 1.02 to 1.10.

Accordingly, the case part 510 is made of a high-density polyethylene resin (HDPE) 110 to 130 (hereinafter, referred to as " HDPE ") based on 100 parts by weight of the polypropylene resin so as to radiate far-infrared rays for improving mechanical properties and twisting phenomenon and promoting metabolism of the body. 1 to 10 parts by weight of talc, 1 to 10 parts by weight of germanium powder, 15 to 25 parts by weight of glass fiber reinforced plastic, 2 to 7 parts by weight of glue, 5 to 10 parts by weight of cork powder, sucrose (C12H22O11) 1 to 4 parts by weight of powder, 2 to 5 parts by weight of alum and 3 to 8 parts by weight of boehmite (AlO (OH)), and having a specific gravity of 1.02 to 1.10.

The plastic composition for manufacturing the case part 510 of the present invention may include a polypropylene resin, a high density polyethylene resin (HDPE), a talc, and a germanium powder.

When the above-mentioned plastic composition is used, it is possible to improve the mechanical properties such as heat resistance and durability, to improve the twisting phenomenon, to promote the metabolism by radiating the far-infrared rays and to improve the storage stability of the food stored in the plastic container It is possible to produce an effect of producing a plastic sheet (product) which can be improved.

Polypropylene resin is a thermoplastic resin which is obtained by polymerization of propylene and is known as an environmentally friendly material which is inexpensive in performance and is free from the risk of contact with the contents of foods or cosmetics. It is excellent in properties and thermal properties.

The polypropylene may be at least one selected from a propylene homopolymer, a random copolymer, and a block copolymer. In order to improve the mechanical properties, a homopolymer and a random copolymer are mixed at a weight ratio of 3: 2 .

High-density polyethylene (HDPE) resin is a synthetic resin produced by polymerizing ethylene, and has excellent flowability, rigidity, impact resistance, electrical insulation, moldability, and cold resistance.

The high-density polyethylene resin may have the effect of improving the formability by mixing with the polypropylene resin to strengthen the tensile force in the production of the plastic sheet or the product, and a variety of known products can be used.

Talc improves mechanical properties such as strength and heat resistance of a plastic composition, and it is preferable to use a talc powder having a particle size of 150 to 200 mesh for mixing with a polypropylene resin or the like.

The talc may be used in admixture with other filler components, and may preferably be mixed with the dolomite powder at a weight ratio of 1: 1 to contribute to improvement of the durability of the plastic composition.

Germanium is a silver-white quasi-metal, which has the effect of promoting metabolism by radiating a large amount of far-infrared rays and anions which are beneficial to the human body.

In addition, germanium, due to its semiconducting properties, causes germanium ions (outer electrons) to enter the body when it comes into contact with the skin, thereby enhancing the vitality. When it enters the body, it is released out of the body in 20 to 30 hours together with various harmful substances. There is no side effect at all.

Particularly, when the particles of inorganic germanium come into contact with human skin, semiconductor properties are introduced into the skin tissue by the osmotic action of the outer electron. It has been found that germanium, which penetrates into capillaries in subcutaneous tissue, moves electrons in blood vessels through blood vessels, cleanses blood, normalizes blood, and discharges excess electrons to relieve pain.

The germanium can be used in the form of a powder. It is preferable that the germanium ore is finely cut to 3 cm or less and then the cut germanium ore is pulverized to a particle size of 80 to 100 mesh.

In one embodiment, the plastic composition preferably comprises 110 to 130 parts by weight of high-density polyethylene resin, 170 to 190 parts by weight of talc, and 1 to 10 parts by weight of germanium powder, based on 100 parts by weight of the polypropylene resin.

When the case part 510 is manufactured using the plastic composition, it is important to control the specific gravity of the plastic composition in order to eliminate the twisting phenomenon. The specific gravity is preferably 1.02 to 1.10, more preferably 1.03 to 1.05 That is, the high-density polyethylene resin is less than 110 parts by weight or the talc is less than 170 parts by weight based on 100 parts by weight of the polypropylene resin, the strengthening of the mechanical properties such as durability is limited, If the high-density polyethylene resin exceeds 130 parts by weight or the talc exceeds 190 parts by weight, the specific gravity of the plastic composition may increase and the moldability may be deteriorated.

If the amount of the germanium powder is less than 1 part by weight with respect to 100 parts by weight of the polypropylene resin, far infrared ray emission effect due to germanium is difficult to manifest. If the amount is more than 10 parts by weight, It can become bad.

In one embodiment, the plastic composition described above may further comprise glass fiber reinforced plastic to enhance impact resistance.

Fiberglass Reinforced Plastic (FRP) is a material in which glass-based minerals are used as main materials and aromatic nylon fibers and thermosetting resins are combined with glass-based minerals.

The glass-based mineral may be at least one selected from the group consisting of silica sand, limestone, feldspar, and soda ash, but is not limited thereto.

As the thermosetting resin, various known thermosetting resins can be used, and preferably, polyester or epoxy resin can be used.

Glass fiber reinforced plastics can be produced by mixing materials such as glass-based minerals and putting them into a melting furnace. Each air layer sealed between glass fibers functions as a heat insulating layer, so that it is excellent in incombustibility, sound absorption property and workability.

Also, it is stronger than iron, lighter than aluminum, and does not rust. It has excellent nonflammability and is not deformed by heat and is easy to process.

At this time, it is preferable to add glue to improve the mixing property with glass fiber reinforced plastic (pellet type) and PVC.

Glue is a substance that solidifies the liquid of an animal such as an animal's skin, intestines, bones, etc., and solves problems such as the release of environmental hormones while improving the binding force of each component.

The glass fiber reinforced plastic and the glue are preferably contained in an amount of 15 to 25 parts by weight and 2 to 7 parts by weight, respectively, based on 100 parts by weight of the polypropylene resin. If the glass fiber reinforced plastic and the glue are less than the above range, If it exceeds the range, the product may be cracked during production and is uneconomical.

In one embodiment, the cork powder may be further included to improve the elasticity of the case part 510 when the plastic part is used.

The cork powder can be prepared by removing the shell of oak oak, and then crushing it. For the cork powder to be mixed with polypropylene resin or the like, it is preferable to use fine pulverized particles which are sieved through a mesh of 400 mesh or more.

The cork powder is preferably contained in an amount of 5 to 10 parts by weight based on 100 parts by weight of the polypropylene resin. When the cork powder is less than 5 parts by weight, the degree of improvement of the elasticity is insignificant. When the cork powder is more than 10 parts by weight, The voids formed in the inside during manufacturing may become large and the durability may be weakened.

In addition, sucrose (C12H22O11) powder may be further added to improve the mixing property of the cork powder and other ingredients.

The sucrose not only smoothes the pores formed between the cork powders but also tends to be viscous in the process of mixing with PVC and the like, which can catch the molecules causing the problem of bad odor, which can contribute to solving the problem of bad odor.

The sucrose is preferably a powder that has been passed through a 500-mesh net, and is preferably contained in an amount of 1 to 4 parts by weight based on 100 parts by weight of the polypropylene resin. When sucrose is less than 1 part by weight, If the amount is more than 4 parts by weight, it is not only economical but also may weaken the mechanical properties of the product.

In one embodiment, the plastic composition may further comprise a white powder. Potassium alum (potassium aluminum sulfate, AlK (SO4) 2 · 12H2O) can be used as the alum, and it can be obtained from natural alum.

Concretely, it can be produced by dissolving alunculus in water and filtering it, then breaking it, and cooling it if irregularly shaped crystals are formed. The alumina is preferably contained in an amount of 2 to 5 parts by weight based on 100 parts by weight of the polypropylene resin. When the alumina content is less than 2 parts by weight, the alumina effect is insignificant.

In one embodiment, the plastic composition according to the present invention may further comprise boehmite (Boehmite, AlO (OH)) to improve antimicrobial properties.

Boehmite can be any of γ-boehmite, a-boehmite and pseudo-boehmite. Among these, boehmite is excellent in crystallinity, excellent in thermal stability and chemical stability, structurally neutral, It is preferable to use an excellent? -Behoeite.

The γ-boehmite can be produced by supercritical synthesis of only water (pure water) and aluminum (Al). It is preferable that boehmite is included in 3 to 8 parts by weight with respect to 100 parts by weight of the polypropylene resin. If the content of boehmite is less than 3 parts by weight, it is difficult to exhibit the antimicrobial effect to be achieved. There is a possibility that the mixing property of the resin is deteriorated.

Hereinafter, the composition and effect of the plastic composition according to the present invention will be described in more detail with reference to specific examples and comparative examples. However, this embodiment is intended to explain the present invention more specifically, and the scope of the present invention is not limited to these embodiments.

[Example 1]

180 kg of polypropylene resin, 200 kg of high density polyethylene resin (HDPE), 310 kg of talc and 15 kg of germanium powder were mixed to prepare a plastic composition.

[Example 3]

9 kg of cork powder, 5 kg of sucrose powder, 5 kg of white powder, and 9 kg of gamma-boehmite were further mixed to prepare a plastic composition.

[Comparative Example 1]

Was prepared in the same manner as in Example 1, except for talc.

[Experimental Example 1: Evaluation of impact resistance]

A specimen (20 cm * 30 cm, thickness 20 mm) was prepared using the plastic compositions of Examples 1 to 3 and Comparative Example 1, and a weight of 3 kg was dropped at a height of 2 m. The degree of breakage of each specimen was measured, The results are shown in Table 1 below.

As can be seen from the above Table 1, it was found that the examples including the talc were superior in impact resistance as compared with Comparative Example 1 which did not include talc. In particular, in Examples 2 and 3 containing glass fiber reinforced plastics, the best results were obtained.

[Experimental Example 2: Evaluation of heat resistance]

The specimen of Experimental Example 1 was heated for 3 hours in a hot air circulating heating furnace maintained at 80 ° C, and yellowing degree was visually observed. The results are shown in Table 2 below.

As can be seen from Table 2, in Examples 1 to 3, yellowing portions were hardly observed unlike Comparative Example 1. As a result, it was found that the heat resistance of the example was much better than that of the comparative example 1.

[Experimental Example 3: Evaluation of antimicrobial activity]

Example 1, Example 3 and Comparative Example 1 were subjected to a test for antibacterial activity (JIS Z 2801). Aspergillus niger ATCC 9642 (fungus) was used as the test strain and the antibacterial activity (antibacterial activity value) was evaluated and shown in Table 3 below.

The antimicrobial activity value refers to a value obtained by evaluating the degree of antimicrobial activity by comparing the number of strains cultured for a certain period of time. When the value is 1 or more, 90% or more of the strains are present, 2 or more are 99% , More than 99.99% of the strain is over 4, and more than 5 is more than 99.999% of the strain is killed.

As can be seen from the above Table 3, it was predicted that the antibacterial activity of Example 3 including gamma-boehmite was much better than those of other cases.

The protection sheet portion 520 is attached to the front surface of the case portion 510 to protect the front surface of the case portion 510.

In one embodiment, the protective sheet portion 520 is made of the same plastic adjustments as the case portion 510 and is made of polyvinyl alcohol (PVA) 1 to 30 parts by weight, based on 30 to 90 parts by weight of the ethylene vinyl acetate (EVA) (MoS2), sodium silicate (3 to 7 parts by weight), calcium carbonate (5 to 30 parts), surfactant (0.1 to 1 part), thixotropic imparting agent (1 to 20 parts) 1 to 5 parts by weight of aluminum hydroxide, 5 to 10 parts by weight of aluminum hydroxide and 10 to 30 parts by weight of water as a solvent and a mixture of toluene-diisocyanate (TDI), hydrogenated TDI, trimethyl propane-TDI (TDI), tripe- nylmethane-triisocyanate (TTI), diphenylmethane-4,4-diisocy- anate (MDI), hydrogenated MDI, and hexamethylene-diisocyanate hexamethylene-diisocyanate, < RTI ID = 0.0 > HDI) Made of a carbonate compound, it may be attached to the front of the case 510 with an adhesive composition comprising a curing agent that is an amount of 1-20 parts by weight per 100 parts by weight of the subject.

In one embodiment, the adhesive composition used to adhere the protective sheet portion 520 is an adhesive composition comprising a topical and a curing agent, the subject of which comprises 30 to 90 parts by weight of an ethylene vinyl acetate (EVA) resin, polyvinyl alcohol 1 to 30 parts by weight of water, 10 to 30 parts by weight of water, 5 to 30 parts by weight of calcium carbonate, 0.1 to 1 part by weight of a surfactant and 1 to 20 parts by weight of a thixotropic agent, can do.

The adhesive composition is a water-soluble two-component adhesive composition composed of a subject and a curing agent, which can be applied and cured to produce an adhesive sheet or an adhesive. The adhesive composition is excellent in physical properties such as adhesiveness and heat resistance Wood board such as plywood, inorganic board such as magnesium board, PVC, and the like.

The subject basically comprises an ethylene vinyl acetate (EVA) resin, polyvinyl alcohol (PVA), water, calcium carbonate, a surfactant and a thixotropic agent, the ethylene vinyl acetate resin being the main component of the subject, The strength of the adhesive sheet or adhesive can be kept constant.

Conventionally, an epoxy resin is used as a main component of an adhesive sheet or an adhesive. However, in the case of an adhesive sheet or an adhesive using an epoxy resin, volatile organic compounds such as benzene toluene are released to adversely affect the environment and human body.

However, the adhesive composition of the present invention can solve problems such as environmental problems by excluding an epoxy resin.

Polyvinyl alcohol (PVA) has a role of improving the heat resistance, water resistance and adhesiveness of an adhesive sheet or adhesive to be produced.

The polyvinyl alcohol is preferably contained in an amount of 1 to 30 parts by weight based on 30 to 90 parts by weight of the ethylene vinyl acetate resin. When the amount of the polyvinyl alcohol is less than 1 part by weight, it is difficult to improve the heat resistance, , The relative content of ethylene vinyl acetate may be reduced and the cohesive force of the adhesive sheet or adhesive may be weakened.

Further, in the present invention, antimony oxide and zirconium oxide may be used together with polyvinyl alcohol in order to supplement the functionality of polyvinyl alcohol when used in an ondol floor or the like.

Antimony oxide and zirconium oxide are materials capable of enhancing the heat resistance of the adhesive sheet or adhesive to be produced and are preferably contained in an amount of 5 to 10 parts by weight based on 30 to 90 parts by weight of the ethylene vinyl acetate resin. The effect of enhancing is insignificant, and when it exceeds the above range, it is uneconomical.

Water can be used as a solvent for the subject.

INDUSTRIAL APPLICABILITY The present invention has the effect of solving the environmental pollution problem without using a volatile organic solvent unlike the conventional adhesive sheet or adhesive.

Water is preferably contained in an amount of 10 to 30 parts by weight based on 30 to 90 parts by weight of the ethylene vinyl acetate resin. When the amount of water is less than 10 parts by weight, ethylene vinyl acetate resin and the like can not be effectively dissolved. The strength of the adhesive sheet or the adhesive may be lowered.

Calcium carbonate modulates the viscosity of the adhesive composition and reduces shrinkage upon curing.

The calcium carbonate is preferably contained in an amount of 5 to 30 parts by weight based on 30 to 90 parts by weight of the ethylene vinyl acetate (EVA) resin. When the amount of calcium carbonate is less than 5 parts by weight, sufficient shrinkage does not occur during curing, If the amount is more than 30 parts by weight, the viscosity may become too tight and the productivity may be deteriorated.

In addition, the present invention may use various materials such as wormwood and clay to replace calcium carbonate. For example, dolomite and / or talc may be used.

In order to improve the mechanical properties, dolomite and talc are preferably mixed at a weight ratio of 1: 1, and the powder preferably has a particle size of 150 to 200 mesh, The use of the finely pulverized powder to improve the mixing property with other components such as ethylene vinyl acetate resin.

The surfactant is used in order to reduce the surface tension when mixing the adhesive composition and to improve the coating property.

The surfactant is preferably contained in an amount of 0.1 to 1 part by weight based on 30 to 90 parts by weight of the ethylene vinyl acetate resin.

As the surfactant, known nonionic surfactants and anionic surfactants can be used, but in order to effectively reduce the surface tension, it is preferable to use a gemini type sulfonic acid type surfactant containing an alkyl chain having 8 to 14 carbon atoms .

The thixotropic agent prevents the adhesive composition from flowing down by suppressing the separation phenomenon between the subject and the curing agent when the adhesive composition is applied to the adhesive sheet or the adhesive, and it is possible to use various known various substances such as silica, acryl copolymer and the like But it is preferable to use a clay.

Clay is an aggregate of fine hydrated silicate minerals. It refers to a material that is mixed with an appropriate amount of water and kneaded to produce plasticity, exhibits rigidity when dried, and sintered when baked at a high temperature.

Specifically, at least one powder selected from the group consisting of kaolinite, fumed silica and bentonite may be used, but in order to obtain the best effect, it is preferable to use a mixture of fumed silica and bentonite in a weight ratio of 1: 1.

The thixotropic agent is preferably contained in an amount of 1 to 20 parts by weight based on 30 to 90 parts by weight of the ethylene vinyl acetate resin. When the thixotropic imparting agent is less than 1 part by weight, the flowability can not be sufficiently controlled, If the amount is more than 50 parts by weight, the flowability may be excessively vanished and the productivity may be lowered.

In addition, the subject may further include sodium silicate to improve the adhesive strength of the adhesive sheet or adhesive to be produced.

Unlike conventional adhesives, sodium silicate does not cause pollution and is environmentally friendly and has excellent adhesion.

The sodium silicate is preferably contained in an amount of 3 to 7 parts by weight based on 30 to 90 parts by weight of the ethylene vinyl acetate resin based on the solid content. When the amount of the sodium silicate is less than 3 parts by weight, If it exceeds 7 parts by weight, miscibility with other components may be deteriorated.

The subject may further include molybdenum disulfide to improve the abrasion resistance of the adhesive sheet or adhesive to be produced.

Molybdenum disulphide (MoS2) is found in thin veins in minerals and is mined and used as a lubricant.

Molybdenum disulfide (MoS2) has inherent characteristics of a hexagonal crystal structure in which shear is easily generated, such as graphite, but the lubricating action is superior to that of graphite.

The molybdenum disulfide is preferably contained in an amount of 1 to 5 parts by weight based on 30 to 90 parts by weight of the ethylene vinyl acetate resin based on the solid content. When the amount of the molybdenum disulfide is less than 1 part by weight, the abrasion resistance can not be effectively improved. If it is exceeded, it may rather deteriorate the adhesive strength.

At this time, copper powder may be mixed with molybdenum disulfide.

Further, the subject may further include a flame retardant agent to improve the flame retardancy of the adhesive sheet or adhesive to be produced.

The flame retardant is preferably contained in an amount of 1 to 5 parts by weight based on 100 parts by weight of the ethylene vinyl acetate resin. When the flame retardant is less than 1 part by weight, the degree of improvement of the flame retardancy is insignificant. In addition, there is a fear that the miscibility with other components may deteriorate.

The flame retardant can be a white powder, which can be a potassium alum (potassium aluminum sulfate, AlK (SO 4) 2 .12H 2 O) and can be obtained from natural alum.

Concretely, it can be produced by dissolving alunculus in water and filtering it, then breaking it, and cooling it if irregularly shaped crystals are formed.

In addition, the subject may further include aluminum hydroxide to improve the antibacterial property of the adhesive sheet or adhesive to be produced.

As the aluminum hydroxide, boehmite (AlO (OH)) is preferably used.

Boehmite can be any of γ-boehmite, a-boehmite and pseudo-boehmite. Among these, boehmite is excellent in crystallinity, excellent in thermal stability and chemical stability, structurally neutral, It is preferable to use an excellent? -Behoeite.

The γ-boehmite can be produced by supercritical synthesis of only water (pure water) and aluminum (Al).

It is preferable that aluminum hydroxide is contained in an amount of 5 to 10 parts by weight based on 30 to 90 parts by weight of ethylene vinyl acetate. When the content of aluminum hydroxide is less than 5 parts by weight, it is difficult to exhibit the antimicrobial effect to be achieved, There is a possibility that the miscibility with other components may be impaired.
