Although not specifically shown, the detector 230 includes a light source that emits a specific wavelength, a filter that filters light from the light source to accurately transmit a specific wavelength, a flow cell containing a reaction sample, and a photodiode that detects light It can be composed of. The light source irradiates the light source toward the photodiode and passes through the flow cell therebetween. The irradiated light is absorbed as it passes through the sample developed inside the flow cell, and reaches the final photodiode by the reduced light intensity. This is called absorbance and is calculated by the following formula. When the intensity of the light emitted from the light source is 'I0' and the reduced light through the flow cell is 'It', it is calculated as 'absorption (ABS) = log10 (I0 / It)'. The light source uses a Xenon Flash Lamp when measuring total nitrogen and an LED lamp when measuring total phosphorus. The light source used for the measurement does not emit only the exact wavelength specified in the specification. That is, light having a wavelength in the range of about ± 5 to 10% is irradiated, and the filter serves to allow the light source to be irradiated with a wavelength used for measurement. This filter is located between the light source and the flow cell to selectively transmit the wavelength of the light source used for the measurement and filters out all other wavelengths. Photodiodes are used for detection, and each detects a signal in a specific wavelength band. A detection photodiode of 220 nm for total nitrogen measurement and 880 nm for total phosphorus measurement is used. Through this, the absorbance of the colored sample is measured, and it appears in proportion to the concentration. That is, the higher the concentration, the darker the color.

Benzimidazole, propylene glycol methyl ether, and bisphenol F-type diglycidyl ether serve to prevent corrosion and discoloration.

Hafnium is a transition metal element with corrosion resistance, and serves to have excellent water resistance and corrosion resistance.

Molybdenum emulsifier plays a role in imparting slidability and lubricity to the surface of the coating film.

Aluminum oxide is added for the purpose of fire resistance and chemical stability.

The cocamidopropyl betaine and ampho glycinate are preferably 1: 0.01 to 1: 2 as the molar ratio, and when the molar ratio is outside the above range, the applicability of the bearing carrier 134 is lowered or moisture is adsorbed on the surface after application. This increases, there is a problem that the coating film is removed.

The cocamidopropyl betaine and ampho glycinate are preferably 1 to 10% by weight in the total composition aqueous solution, and if it is less than 1% by weight, there is a problem that the applicability of the bearing transporter 134 decreases, and 10% by weight If exceeded, crystal precipitation tends to occur due to an increase in the thickness of the coating film.

Since carbon black increases abrasion resistance, it is added, but if the content is less than 33% by weight, elasticity and abrasion resistance decreases. , 33 to 36% by weight.

Antioxidant is 3C (N-PHENYL-N'-ISOPROPYL- P-PHENYLENEDIAMINE) or RD (POLYMERIZED 2,2,4-TRIMETHYL-1,2- DIHYDROQUINOLINE) and 2-5% by weight is added. If it is less than weight%, the product is apt to be oxidized, and if it is added too much and exceeds 5% by weight, the content of rubber as a main component is relatively small, and thus elasticity may be deteriorated. ~ 5% by weight is appropriate.

The accelerator, sulfur, is mixed with 1 to 3% by weight. Less than 1% by weight, since the vulcanization effect in the heating process during molding is negligible, 1% by weight or more is added. If it exceeds 3% by weight, since the content of rubber as a main component is relatively small, there is a fear that elasticity may drop, 1 to 3% by weight is appropriate.

Therefore, the present invention is reinforced with synthetic rubber having elasticity in various directions, so that the elasticity, toughness and rigidity of the belt 136 are increased, thereby improving durability, and accordingly, the life of the belt 136 can be increased.
