The Poiints that need to be paid attention in the application of the mold heating element.
Pay more attention to the following points in the application of mold heating element. pipe:
1. When the mold heating element. is used to heat the chemical substances such as nitrate, paraffin and leach of soluble metal or solid, the heating chemical should be melted first. At this time, the external working voltage of the mold heating pipe can be reduced, and the rated current can be restored after the melting. In addition, safety precautions should be taken into account when heating the mold heating element. with nitrate and other chemicals which are very easy to cause explosion.
2. When the mold heating element. is used for air heating, pay attention to the symmetrical order of the mold hheating element.. The benefit of doing so is to ensure that the mold heating element. has sufficient and symmetrical heat pipe heat dissipation indoor space, and ensure the gas circulation as far as possible, and improve the heating efficiency of the mold heating pipe.
3. There is magnesia in the gap inside the mold heating pipe. Magnesia is very easy to suffer environmental pollution due to the penetration of residue and water at the outlet end of the mold heating pipe group. Therefore, attention should be paid to the situation of the outlet end of the mold heating pipe group in the actual operation, so as to prevent the leakage safety accidents caused by it.
4. The storage part of mould heating pipe must maintain dry and moderate grounding resistance. If it is found that the natural environment grounding resistance of mold heating pipe is too small, it can be applied again after repairing with low-voltage power supply. The mould heating pipe should be properly fixed before application, and part of the wiring should be placed outside the insulation layer to prevent contact with corrosion, combustible materials and water.
5. When the mold heating element. is used for heating liquid or metal material solid state, it is necessary to pay attention to make sure that the mold heating pipe is completely embedded in the heated object block, and the empty burning of the mold heating pipe is not allowed. If there is dirt or carbon on the surface metal hose shell after the application of mold heating pipe, it should be eliminated immediately to prevent the heat dissipation characteristics and service life of the mold heating element.
