  • Annealing is to restore the plasticity of wire, improve the tensile strength of wire, hardness, elastic limit, etc., the wire after annealing is called annealing wire. In the production process of annealing wire, it is very important to ensure the quality of the finished wire, make the wire have certain strength and suitable degree of soft and hard. The annealing temperature is between 800 ℃ and 850℃, and the length of furnace tube is lengthened appropriately for enough holding time.

  • The lighting surface of each type of shed is designed to be curved, improving the Angle of the light surface, because the lighting surface is curved, no dust accumulation, good light transmittance, high temperature in the shed, after measurement, the average temperature in the shed is 3℃ higher than the traditional bamboo pole cement column shed, the yield is increased by 15~20%, and the harvest date is advanced. The formula is scientific, the surface does not absorb moisture, do not return halogen through modification technology and scientific production process, solve the greenhouse frame rod is easy to absorb moisture return halogen, poor water resistance and easy to change the shortcomings, so that the greenhouse steel pipe in the high temperature and high humidity environment, few drops, frost phenomenon, and reduce pests and diseases.
