Ground heating is the heating method that uses the whole ground as a source of low-temperature radiant heating. It has the advantages that other heating methods are incomparable. It is consistently considered to be the most scientific and reasonable, the most comfortable and healthy, the most economical and energy-saving heating method. The theory of traditional Chinese medicine health, which is in line with the ancients' warm foot and cold head, is incomparable to other heating methods. It is an efficient heating system that regulates the microclimate of the room.
The main heating material for floor heating is an ultra-thin electric heating film without laying pipes, which is very convenient to install.
Because you don't use expensive boilers, you save a lot of money.
The main heating material is an ultra-thin electric heating film that does not affect the height of the house. The warm-up time is short, and the power is hot.
The electric heating film generates a large amount of far-infrared rays when it is heated, and has a good health effect on rheumatism, arthritis, balance of acidity of the body, and promotion of metabolism.
The base material is: a polyester film. The composition is: polyethylene terephthalate. The characteristics are: excellent electrical performance; good mechanical strength; dimensional stability; melting point between 150-260 ° C; below 100 ° C will not accelerate aging.
The heating element material is: specially formulated ink. The ingredients are: graphite and the like. Graphite is a solid element in the carbon group, which is a homologous element with diamond. Its characteristics are: its highest melting point of 3773K is only 50 °C lower than diamond. Due to the presence of free electrons, graphite is slightly more chemical than diamond, but it is still inert in chemical reagents. Based on its characteristics, its service life is very long.
The current-carrying strip material is: metallic copper (nickel plated). The current-carrying strip process is copper-plated nickel. The characteristics are: copper and gold are the only two metals that exhibit a special color in all metals. The density, melting point, boiling point and hardness of the copper group elements are higher than the corresponding alkali metals. The conductivity and heat transfer properties of the copper group elements are the best among all metals, with silver taking the lead and copper being the second. Copper is relatively stable in dry air and does not react in water. Due to its corrosion resistance, stability and ease of machining, it is widely used in industry. Nickel has good ductility and certain corrosion resistance.
The ink is printed on a mylar film, and the two layers of polyester film are compounded by a special hot pressing process. The product is produced by an insulating process and can be operated in water. The heating zone is a parallel line.
Phosphorus fertilizer uses phosphorus as the main nutrient fertilizer. The full name of phosphorus fertilizer. Phosphate Fertilizer effect of the significant degree and speed is determined by the phosphorus content of phosphorus pentoxide, soil properties, fertilization methods, crop types and so on.
Appropriate application of phosphate fertilizer can increase crop yield, improve crop quality, speed up the dissection of grain crops and promote full grain filling; promote the flowering of cotton, melons, solanaceous vegetables and fruit trees, and increase fruiting rate; increase sugar beet, sugar cane, watermelon, etc. Sugar; rapeseed oil content.
