In this case, a groove may be formed on one surface of the second mounting base portion 245, and the upper surface and the lower surface of the second mounting surface 21 may be fitted into the groove of the second mounting base portion 245 The protrusion 215 may be formed. The second mounting base portion 245 can be mounted on the upper surface or the lower surface of the second seating surface 21 by engaging the projection 215 with the groove.

An abrasion-resistant coating layer may be formed on the surfaces of the first roller 14 and the second roller 24 of each of the first mounting roller portion 1 and the second mounting roller portion 2, respectively. Thus, it is possible to minimize the shortening of the service life of the first roller 14 and the second roller 24, which rotate on the ground for moving the object 0.

Here, the wear-resistant coating layer is composed of a mixture of 96 to 98% by weight of chromium oxide (Cr 2 O 3 ) and 2 to 4% by weight of titanium dioxide (TiO 2 ), and the powder is mixed with the first roller 14 and the second roller 24 ), Each having a thickness of 50 to 600 mu m, and the hardness is plasma-coated to maintain 900 to 1000 HV.

The wear-resistant coating layer is formed by spraying powder composed of 96 to 98% by weight of chromium oxide (Cr 2 O 3 ) and 2 to 4% by weight of titanium dioxide (TiO 2 ).

The reason why the ceramic coating is applied to the outer circumferential surfaces of the first roller 14 and the second roller 24 is to prevent abrasion and corrosion. Compared to chrome plating or nickel chrome plating, the ceramic coating is excellent in corrosion resistance, scratch resistance, abrasion resistance, impact resistance and durability.

Chromium oxide (Cr 2 O 3 ) acts as a passivity layer to block oxygen entering the inside of the metal, thereby preventing rusting.

Titanium dioxide (TiO 2 ) is a white pigment because it is very stable physicochemically and has high hiding power. And is also widely used for ceramics having high refractive index because of high refractive index. And has characteristics of photocatalytic property and superhydrophilic property. Titanium dioxide (TiO 2 ) acts as an air purification function, an antibacterial function, a harmful substance decomposition function, a pollution prevention function, and a discoloration prevention function. The titanium dioxide (TiO 2 ) ensures that the wear-resistant coating layer is coated on the outer circumferential surface of each of the first roller 14 and the second roller 24, and the foreign substances adhered to the wear- Thereby preventing the coating layer from being damaged.

Here, chromium oxide (Cr 2 O 3) and when using hayeoseo mixing titanium dioxide (TiO 2), the mixing ratio of these, chrome oxide (Cr 2 O 3) Titanium dioxide (TiO 2) in 96-98% by weight 2 By weight to 4% by weight.

When the mixing ratio of chromium oxide (Cr 2 O 3 ) is less than 96 to 98%, the coating of chromium oxide (Cr 2 O 3 ) is often broken in an environment such as high temperature, 14 and the second rollers 24, respectively.

When the mixing ratio of titanium dioxide (TiO 2 ) is less than 2 to 4 wt%, the effect of titanium dioxide (TiO 2 ) is insignificant so that the purpose of mixing it with chromium oxide (Cr 2 O 3 ) is discolored. That is, titanium dioxide (TiO 2 ) decomposes and removes foreign matter adhered to the outer circumferential surface of each of the first roller 14 and the second roller 24 to remove the foreign matter of the first roller 14 and the second roller 24 The outer circumferential surface is prevented from being corroded or damaged. When the mixing ratio is less than 2 to 4% by weight, it takes a long time to decompose the attached foreign matter.

The coating layer made of these materials has a thickness of 50 to 600 mu m around the outer circumferential surface of each of the first roller 14 and the second roller 24 and has a hardness of 900 to 1000 HV and a surface roughness of 0.1 to 0.3 mu m Lt; / RTI >

The abrasion resistant coating layer is formed by jetting the powdered powder and the gas at 1400 DEG C around the outer circumferential surface of each of the first roller 14 and the second roller 24 at a Mach 2 speed, do.

If the thickness of the wear-resistant coating layer is less than 50 탆, the above-mentioned effect of the ceramic coating layer can not be guaranteed. If the thickness of the wear-resistant coating layer exceeds 600 탆, the above- There is a problem that working time and material cost are wasted.

The temperature of the outer circumferential surface of each of the first roller 14 and the second roller 24 is raised while the wear-resistant coating layer is coated on the outer circumferential surface of each of the first roller 14 and the second roller 24, The outer circumferential surface of each of the first roller 14 and the second roller 24 is cooled by a cooling device (not shown) so that deformation of the outer circumferential surface of each of the roller 14 and the second roller 24 is prevented, Thereby maintaining the temperature.

A sealing material made of anhydrous chromic acid (CrO 3 ) made of a metal-based glass quartz system may further be applied to the periphery of the abrasion-resistant coating layer. Anhydrous chromic acid is applied as an inorganic sealing material around a coating layer made of chromium nickel powder.

Anhydrous chromic acid (CrO 3 ) is used in places that require high abrasion resistance, lubricity, heat resistance, corrosion resistance and releasability, is not discolored in the atmosphere, has high durability, and has good abrasion resistance and corrosion resistance. The coating thickness of the sealing material is preferably about 0.3 to 0.5 mu m. If the coating thickness of the sealing material is less than 0.3 占 퐉, the sealing material easily peels off even in a slight scratch groove, so that the above-mentioned effect can not be obtained. If the coating thickness of the sealing material is made thick enough to exceed 0.5 탆, pin holes, cracks, and the like will increase on the plated surface. Therefore, the coating thickness of the sealing material is preferably about 0.3 to 0.5 mu m.

Therefore, since the coating layer having excellent abrasion resistance and oxidation resistance is formed around the outer circumferential surface of each of the first roller 14 and the second roller 24, the outer circumferential surface of each of the first roller 14 and the second roller 24 is worn or oxidized And thus the life of the product is prolonged.

The first and second wall surfaces 22 and 23 and the first and second wall surfaces 22 and 23 and the first and second wall surfaces 22 and 23, ) May be made of plastic.

More specifically, each of the first seating surface 11, the first wall surface 12, the first neighboring wall surface 13, the second seating surface 21, the second wall surface 22 and the second neighboring wall surface 23 The silver case may be formed of a polypropylene resin composition having excellent impact resistance against external impact or external environment.

The polypropylene resin composition comprises a polypropylene random block copolymer composed of 75 to 95% by weight of an ethylene-propylene-alphaolefin random copolymer and 5 to 25% by weight of an ethylene-propylene block copolymer having an ethylene content of 20 to 50% by weight .

The polypropylene random block copolymer is preferably 75 to 95% by weight of the ethylene-propylene-alphaolefin random copolymer and 5 to 25% by weight of the ethylene-propylene block copolymer. The ethylene- When the content of the ethylene-propylene block copolymer is less than 5% by weight, the impact resistance is deteriorated. When the content of the ethylene-propylene block copolymer is more than 25% by weight, the rigidity is deteriorated do.

Wherein the ethylene-propylene-alpha olefin random copolymer comprises 0.5 to 7% by weight of ethylene and 1 to 15% by weight of an alpha-olefin having 4 to 5 carbon atoms and improves mechanical stiffness and heat resistance of the polypropylene resin composition, As shown in Fig.

The ethylene content is preferably from 0.5 to 5% by weight, more preferably from 1 to 3% by weight. When the content of ethylene is less than 0.5% by weight, the whitening resistance is deteriorated. When the content is more than 7% by weight, . Further, the alpha olefin means any alpha olefin except ethylene and propylene, and is preferably butene. When the number of carbon atoms is less than 4 or more than 5, the reactivity of the alpha-olefin with the comonomer is low during the production of the random copolymer, making it difficult to produce the copolymer.

Further, it may contain 1 to 15% by weight, preferably 1 to 10% by weight, and more preferably 3 to 9% by weight of the above-mentioned alpha olefin. If the amount of the alpha-olefin is less than 1% by weight, the crystallinity becomes higher than necessary and the transparency is lowered. When the amount of the alpha-olefin is more than 15% by weight, the crystallinity and rigidity are lowered and the heat resistance is significantly lowered.

In addition, the ethylene-propylene block copolymer contains 20 to 50% by weight of ethylene and imparts impact resistance to the polypropylene resin composition and enables finely dispersing, thereby imparting both whitening resistance and transparency. The ethylene content may preferably be 20 to 40% by weight, and if it is less than 20% by weight, the impact resistance is deteriorated. If it exceeds 50% by weight, the impact resistance and whitening resistance may be deteriorated.
