2, cast iron radiator: old cast iron radiator due to its low pressure, large size, rough shape, many high energy consumption can not overcome the disadvantages will gradually be eliminated by the market. At present, the cast iron radiator industry has accelerated the pace of developing new products, and gradually developed new products that are novel, energy-saving and material-saving. The cast iron radiators will be introduced to the market with a new image.
3, steel radiator: According to the style points are mainly plate and column two. Steel column radiators, with their rich colors and beautiful appearance, have won the favor of many consumers. Buy steel radiators to consider whether to match the district's heating system, the use of open heating systems for heating consumers should be careful to use steel radiators, because steel radiators are prone to oxidation corrosion in oxygen, open boiler Oxygen content in water and water have strict requirements, all need to be filled and maintained in the main system after the heating period has passed. If the maintenance is not good, the radiator will quickly replenish and eventually cause radiator leakage.
4. Copper-aluminum composite radiators: They are excellent in appearance, corrosion resistance and heat dissipation, and are mainly used in the northern markets and high-end markets, poor water quality areas, and gas-fired boilers as heat sources. It has become the mainstream of middle and high school projects and retail in the northern markets. Due to the quality problems of the steel column radiators produced by some manufacturers gradually exposed during use, people's recognition of copper-aluminum composite radiators is still increasing.
Hydroxypropyl Methylcellulose is soluble in water and some organic solvents. Its aqueous solution has surface activity. The solubility changes with the viscosity. The higher viscosity, the better solubility. The performance is different for different hydroxypropyl methylcellulose HPMC. Hydroxypropyl methylcellulose HPMC solubility is not affected by PH value.
hydroxypropyl methylcellulose used in Plastic
-Used as forming release agent, softening agent, lubricant.
hydroxypropyl methylcellulose used inPolyvinyl Chloride (PVC)
-Used as dispersing agent in polyvinyl chloride production and is the main auxiliary for the suspension polymerization of PVC
hydroxypropyl methylcellulose also used widely in the industry of leather, paper products, textile, fruits and vegetables fresh keeping, etc.
