The copper-aluminum composite radiator has light weight and high metal heat strength. It is used in hot water and steam heating systems. The temperature of the heat medium is not higher than 95 ° C, chloride ion (Cl-), Chemcial Additives Powder mainly include OB powder, OB-1 Powder, FB-127, Optical Brightener Agent, optical brightner KCB , Optical Brightener KSN, optical brightener KSB, Optical brightener KB, Optical brithener DBH, Optical brightener PF, optical brightener OB-2, no Fluorescent Brightener. son Optical Brighteners For Plastic Resin And Rubber Optical Brighteners For Rubber,Optical Brighteners For Plastic Resin Anda Masterbatch( Group) Co., Limited , https://www.polymer-masterbatch.com
The copper-aluminum composite radiator has light weight and high metal heat intensity. It is used in hot water and steam heating systems. The temperature of the heat medium is not higher than 95 °C, and the chloride ion (Cl-) and sulfate ion (SO42-) are not more than 100 mg respectively. /L. The pressure is 1.2Mpa. The heating heat exchanger should be placed on a solid wall or securely supported by a heat sink. The bottom of the radiator is 100mm 150mm from the ground. The heating heat exchanger should be placed under the window sill or on the side of the window sill. In the non-heating season, full water conditioning can extend the life of the radiator; when the indoor temperature is lower than 0 °C, the water inside the radiator should be drained to avoid cracking. Thin wall (1.2 wall thickness 1.5)
The inner cavity sandless cast iron radiator accepts the rare earth cast iron material, the product layout is more compact and elegant, the metal heat strength is obviously improved, and the pressure bearing ability can reach 1.0Mpa. There is no sand in the inner cavity, so it is used for heat metering and temperature control skills. The appearance of electrostatic spraying, smooth and elegant, the decorative performance has produced a qualitative change, suitable for the surface, no need to cover. It is used in China's current hot water heating system and water quality, and can also be used in steam heating systems. It is widely used, non-heating season, no need to fill water, no peace of mind.
The steel radiator is welded by steel pipe. The inner cavity of the steel pipe is subjected to anti-corrosion treatment and punishment. The heat dissipation performance is good, the metal heat strength is high, and the decoration result is good. It is suitable for surface mounting, no need to cover, and it should be properly placed for room temperature treatment. Temperature control valve. The steel pipe heating radiator is only used in the closed hot water heating system. The water temperature is not more than 120 °C, otherwise it will easily produce severe oxygen corrosion and electrochemical corrosion leakage signs, and the life of the radiator is low. Not suitable for steam direct supply heating system. The radiator should be placed under the window sill or on the side of the window sill. In the non-heating season, it should be filled with water; when the indoor temperature is lower than 0 °C, the water inside the radiator should be drained to avoid freezing cracks. The stress is 1.0Mpa. Steel thick-walled radiators are not limited by this.
