Nowadays, electrical or electronic products cannot do without an adhesive in the manufacturing process. This adhesive is silicone potting. The emergence of silicone potting effectively improves the practicality and safety of electrical appliances. Although silicone potting is good, it is necessary to master the correct operation method. The operation process of different types of silicone potting is very different.
Operation method of silicone sealant:
1. Check whether the surface of the construction substrate is clean and tidy before injecting glue. The injection methods of silicone sealant are divided into manual injection and use of dispensing gun. If the silicone sealant belongs to large-capacity specifications, it is more appropriate to use a dispensing gun at this time.
2. Inject glue in a normal temperature environment, the surface drying time is 3 to 15 minutes. At this time, the substrate cannot be moved. It must be moved after it is completely cured to avoid displacement of the bonded parts. Completely cured after 24 hours.
Manual operation method of two-component silicone potting:
1. Weigh the two components of silicone potting separately, and then stir them in turn. After the two components of glue are fully stirred, pour the A component glue into the B component and stir them again.
2. The glue after stirring can be directly used to pot the substrate. After potting, it is placed in a natural environment or a heated environment for curing. In order to prevent the generation of bubbles, the glue can be vacuum degassed after mixing, so that bubbles can be effectively avoided when injecting glue into the substrate. The curing time varies according to the ratio, and there are fast curing times and slow curing times.
Machine operation method of two-component silicone potting:
1. Weigh the two different components of glue separately, and then place them in the preheated machine for stirring.
2. Only after stirring evenly can the glue be injected, which effectively prevents the glue from precipitating and stratifying. Only after curing can the expected performance be bonded.
Large-scale construction is more suitable for machine injection, and manual injection can save the cost of machine purchase. No matter which method is used, as long as the correct construction and curing are completed, the same curing effect can be achieved. In order to facilitate users‘ different needs of glue injection, it is recommended to buy branded products, such as TENSAN, which focuses on the research of silicone potting and provides customized silicone potting application solutions. It has a wide range of uses and can be applied to new energy, military, medical, aviation, shipbuilding, electronics, automobiles, instruments, power supplies, high-speed rail and other industries. This type of glue has the same performance after curing, whether it is injected manually or by machine.
