Many customers want the hot runner coil heater to be evenly heated, and the temperature deviation is not too large. How is the heating tube uniform? Need to pay attention to the two aspects of production processing and on-site use.
First, how is the temperature of the coil heater uniform?
1, the hot coil heater itself,
(1) It can be concluded from the structure of the coil heater that the heating wire of the heating element directly affects the temperature uniformity. Firstly, the quality of the heating wire is good, and the winding wire is evenly distributed, and finally arranged evenly along the true axial direction of the tube casing.
(2) Select high-quality magnesium oxide powder, use automatic filling machine to fill, compact compaction.
2, the use of attention:
(1) When the mold and mechanical equipment are heated, clean the residual contaminants in the mold holes.
(2) Arranged at reasonable intervals to ensure that the heat generated by the heating pipe is dissipated in time.
(3) Do a good job of temperature control.
Heating element are widely used in various sectors of the national economy to heat air, liquid and solid media. They have achieved good economic effects in industrial and agricultural production and people's lives. What are the uses of heating pipes? The details can be summarized as follows:
1. In industrial and agricultural production:
(1) Metal heat treatment, easy melting metal smelting, uniform heating, accurate temperature control;
(2) solid nitrate, paraffin, asphalt and other substances;
(2) in the light industry, food, wood, paper, cotton wool, rubber, plastic, printing and dyeing, etc.;
(3) In petrochemical industry, the heat of the crude oil pipeline, the drying of the tank heating and heating paint, and the refining of chemical fertilizer;
(4) Planting in greenhouses, hatching of poultry, freshwater, marine aquaculture, etc.
