Cold storage anti-corrosion and anti-frost coatings effectively solve the problem of frosting and corrosion

In the cold storage, when the dew point of the air is lowered by the cooling pipe surface, the moisture in the food and air will precipitate and condense on the pipe wall. If the pipe wall temperature is lower than 0°C, it will condense into a rain layer. Experts of okmarts.com anti-corrosion and frosting coatings pointed out that the thermal conductivity of the frost layer of the cooling pipe is more than 80 times smaller than that of steel. The existence of the frost layer will obviously affect the heat transfer coefficient of the cooling pipe. For the finned tube, the effect of the frost layer is more obvious. It not only increases the thermal resistance of heat conduction, but also reduces the heat transfer area of the finned tube, hinders the air flow between the fins, and reduces the heat transfer coefficient on the outer side of the tube. According to the experiment, when the temperature difference between the two sides of the cooling tube group is δt=10℃, the heat transfer coefficient of the tube group is only about 70% of the original after one month of operation. Both the frost layer and the oil layer worsen the heat transfer conditions, reduce the cooling efficiency and increase the power consumption. Therefore, the defrosting of the hoisting pipe must be done in time.

According to the frosting condition of the cold storage cooling pipe, apply ZS-611 anti-icing coating, also called anti-icing and snow coating, which is a high-tech special functional coating independently produced by okmarts.com, which is mainly composed of alternating multi-block inorganic-organic It is composed of interpenetrating network polymer (IPN) base material and highly active nano anti-icing and snow additive after surface modification treatment. ZS-611 anti-icing and snow coating is suitable for various coating methods. It can be self-curing at room temperature and form a dry coating film of less than 30μm on the surface of the protected object, which can prevent the adhesion of ice and snow. Self-cleaning and other composite functions can be used in aircraft, ships, power lines, telecommunications lines, transportation and other structures that require ice and snow and non-stick coating.

Anti-frosting coating, ZS-611 anti-icing and snow coating, the coating is composed of alternately arranged multi-block inorganic-organic interpenetrating network polymer (IPN) base material and high-activity nano anti-icing and snow additive after surface modification treatment. Presents a shell-core double-layer structure. This structure not only shows the excellent performance of the contact angle and rolling angle of the ZS-611 anti-icing and snow coating, but also shows certain elastic structural characteristics. When covered with snow and water, it actively reduces the contact area with snow and water. , Less friction. After the ZS-611 anti-icing and snow coating is applied to the solid surface, a thin layer of specially oriented hydrophobic molecules can be formed on the surface of the material to be protected, which is essentially equivalent to building a layer of self-contained layer between the protected surface and the ice crystals.洁 Separating membrane.

The acceptance test data shows that the ZS-611 anti-icing and snow coating can withstand low temperature above -45℃, the hydrophobic angle can reach 160 degrees, and the rolling angle is less than 8 degrees. The contact angle is greater than 105°, and the surface energy is less than 20x10-3N/m. Compared with ordinary glass materials, the ZS-611 anti-icing and snow coating coating has 6 times higher water sliding properties, 4 times shorter sliding time, 4 times higher snow sliding properties, and 3 times shorter sliding time.

　　 Another important reason for the slow drop in cold storage temperature is the low heat transfer efficiency of the evaporator, which is mainly caused by the thick frost layer on the surface of the evaporator or excessive dust accumulation. Since the surface temperature of the cold storage evaporator is mostly lower than 0℃, and the humidity in the warehouse is relatively high, the moisture in the air is very easy to frost or even freeze on the surface of the evaporator, which affects the heat transfer effect of the evaporator. Paint ZS-611 The anti-icing and snow coating effectively solves the problem of frosting and anti-corrosion of the cooling pipe.
