Potting glue is a kind of composite material that is liquid before curing, has certain fluidity, and solidifies under certain time, heating or other conditions to form an elastomer. Its main function is to be used for bonding, sealing, potting, and coating protection of electronic components, and to play the role of waterproof, moisture-proof, dust-proof, corrosion-proof, and shock-proof. With the development of the electronic and electrical industry, potting adhesives have also been more and more widely used.
When using the potting compound, sometimes it will not cure, and this phenomenon is called the poisoning of the potting compound. What are the reasons for the poisoning and non-curing of silicone potting glue? Today, I will talk about the reasons and solutions for this phenomenon.
As the most representative heat-conducting silica gel sheet in heat-conducting materials, it is mainly made of organic silica gel and has certain ductility. It can well fill the gap between the heating element and the heat sink, remove the air on the uneven surface, and form a good heat flow channel. What kind of thermal silica gel sheet can be called good? What aspects should we start with when investigating a thermal silica gel sheet?
In recent years, thermal gel has attracted more and more attention, and its application has also been verified. More and more high-end compact electronic products will choose thermal gel, and the price will be higher than that of thermal grease. Some people think that there is not much difference between thermal conductive silicone grease and thermal conductive gel. In fact, thermal conductive gel has more advantages than thermal conductive silicone grease in terms of thermal conductivity.
Thermally conductive silicone pads and thermally conductive silicone grease are both thermally conductive interface materials and are widely used in electronic products. So which thermally conductive silicone sheet or thermally conductive silicone grease has a better heat dissipation effect? What are the advantages and disadvantages of each of them? How to choose thermal silicone gasket and thermal grease?
Although the heat dissipation paste is unattractive, it plays a vital role in the electrical appliance manufacturing industry. Now the performance of electrical appliances is getting better and better, and there is almost no phenomenon of burning. It is because the heat dissipation paste is applied during the manufacturing process to enhance the heat dissipation performance. , Comprehensive protection of electrical appliances.
