It is resistant to atmospheric, seawater and chlorine and is excellent in abrasion resistance and cut with tungsten carbide As metal compounds used in tools, there are also many advantages in using pulverized waste tools.

Boron carbide (B ₄ C) is a metal compound used as abrasive, fire retardant, etc. at SP 2.6, melting point (mp) 2,350 ° C,

In addition, alumina is at least alumina containing at least 80% of α-alumina, and has a specific gravity of 3.99, a melting point of 2,060 ° C., and a hardness of 9 or so, so it is used as an abrasive and fire retardant.

In addition to clay and talc, MnO ₂ , TiO ₂ , SiO ₂ , 2Mg · SiO ₂ , MnF ₂ , CaF ₂ , CaO and BeO are added as additives.

The above super-hard metal compounds are metal compounds having excellent abrasion resistance, heat resistance, corrosion resistance and chemical resistance, and they remain unmelted in the metal fusing layer at the time of firing, and remain in the unmelted state of the following low- And a high wear resistance and a slip prevention function are exhibited by the particles of the super hard metal compound.

If the amount of the superalloy metal is larger than the composition ratio of the superalloy metal, the fixing force by the molten metal is reduced, the superalloy alloy particles can be removed, the durability can be shortened, and the economical aspect of the expensive superalloy alloy metal is also considered .

Among the low melting point metals rich in ductility and conductivity, nickel has a specific gravity of 8.98 and a melting point of 1,455 ° C, which is the highest among the low melting point metals. However, by using fine powders of several microns and using a flux, Melted.

It protects internal structure by forming dense oxide film on the surface in air. It is advantageous in that it is inexpensive compared to metal and can secure competitiveness.

In addition, magnesium has a specific gravity of 1.74 and a melting point of 650 ° C which is similar to aluminum and improves the strength and corrosion resistance of aluminum, which is a metal that is easy to alloy and weak in softness and corrosion resistance.

Manganese has a specific gravity of 7.44 and a melting point of 1,245 ℃. It is corrosion resistant and has high hardness. It is highly compatible with aluminum, so it can be added together with magnesium to improve corrosion resistance and strength. However, adding a large amount can improve the corrosion resistance and strength.

Of the low melting point metals which are used in the largest amount in order to firmly fix the particles of the super hard metal compound in the anti-slip composition, since the aluminum is cheap, the economical efficiency is taken into consideration. .

Beryllium is a very light and hard metal with a specific gravity of 1.85 and a melting point of 1,280 ° C. Since the base material of the metal fusing layer is steel, the surface of the iron and the metal fusing layer are fixed as different materials. Although large shear stress is generated at the interface, shear stress can be reduced by low-temperature metals which are excellent in ductility and ductility, but it is easy to generate a gap and easily oxidized. In particular, since beryllium is a metal that imparts excellent oxidation resistance at a portion contacting with iron, it can be said that the base metal is a metal composition necessarily required in a non-slip metal fusing composition using iron.

As the flux, calcium fluoride (CaFe2) is used, the melting temperature of the metal can be lowered, the impurities in the metal can be desorbed, the fluidity of the metal fluid can be increased, and the homogeneity of the metal layer structure can be ensured, have.

In addition, the binder may be prepared by adding a microparticulate adhesive material to the metal particles or powder to adhere the metal particles and powders of the anti-slip composition to the upper surface of the horizontal or vertical support, or the surface of the steel plate frame, (0.5 ~ 1mm) to facilitate bonding to the base material. The binder used herein may be wax, milk currant, cellulose or synthetic resin dissolved in an organic solvent, soap, etc. In a non-slip composition, the maximum amount used is 8.5 wt% and the minimum amount used is 6 wt% The moldability and printability are good, but after the calcination treatment, many pores are formed in the metal layer, the structure is not dense, and the fixing force is decreased.

It is extremely difficult to form a metal layer on a narrow support of 6 mm.

The sintering treatment was carried out by sticking a non-slip coating composition onto each support and the surface of the "a" iron plate frame, pushing it into a furnace in a non-oxidizing atmosphere maintained at a temperature of 500 DEG C, The firing is completed over time.

During the firing process, the binder in the non-slip colloidal composition decomposes or burns at 500 to 600 占 폚. Since the hardness of the super hard metal layer formed on the cover of the drainage pipe obtained through the above process is gathered to show hardness of 8 or more, it is excellent in abrasion resistance and slip prevention function and excellent in oxidation resistance, chemical resistance and base material adhesion strength, It can be said to be a drainage cover having a slip prevention function.
