Thermally conductive silicone grease is a common thermally conductive material and has been used in many electrical appliances. Although thermally conductive silicone grease is classified as a chemical substance, it does not corrode metals, plastics, ceramics and other substrates. During use, volatiles will not be released on the substrate of electrical appliances to ensure human health.
What happened to the thermal grease drying?
1. When the thermal grease becomes dry, first check whether the surface is dry. If the surface is slightly dry, this is normal. Even if you use a big brand product, there will be oil separation and the surface will be slightly dry.
2. The drying of thermal grease may also be caused by poor quality. The main raw material of thermal grease is silicone oil, and then some heat-resistant and thermal conductive materials are added to make it thermally conductive. Inferior products can use cheap raw materials. These raw materials will dry out after a period of use. At this time, the thermal conductivity is seriously threatened. It is not recommended to buy such products.
Does thermal grease have thermal conductivity after drying?
If the thermal grease is only slightly dry without cracking, the thermal conductivity effect still exists. If the thermal grease becomes more serious, it has been severely dried, and even multiple cracks have appeared, and there is no thermal conductivity effect at this time. Because the role of thermal grease is to fill the gap, the heating element of the electrical appliance is in complete contact with the radiator, and the heat generated is transferred as much as possible.
Thermal grease is a common heat dissipation material. This kind of heat dissipation material is not only used in household appliances, but also widely used in electronic instruments, meters and other fields. The price is related to the brand and thermal conductivity index. The thermal conductivity of the same brand of thermal grease is different, and the price is also different.
