Specific application of adhesives for small household appliances

As a product used for bonding and sealing, adhesive and mechanical connection are complementary to each other. With the increasing demand for product quality in recent years, some high-performance silica gel, anaerobic adhesive and polyurethane products are increasingly used in household appliances.
Adhesives are widely used in the production of household appliances, and almost every household appliance product will use adhesives more or less in the production process. For example, polyurethane or hot melt adhesive products are required for the bonding and sealing of various plastic parts and metal parts in the production of washing machines; In order to prevent the bolt from loosening, thread locking glue is also used in the process; Thread sealant will also be used in the water heater pipeline to achieve sealing effect; In microwave ovens, electric ovens, range hoods and other kitchen appliances, high temperature resistant silica gel is used.

Advantages of adhesives
Uniform stress distribution.
No damage to the substrate.
Reduce manpower and improve efficiency.
Realize simultaneous bonding and sealing.
Improve the appearance and make unique design.
Compared with the mechanical method of connection, it has certain flexibility.
Suitable for different strengths for various applications.

New trend of home appliance market

With the use of new structures and materials in the design and production of household appliances, different bonding materials require different adhesives, which puts forward new requirements for the bonding effect of adhesives. Many factors need to be taken into consideration when choosing the adhesive in the production process of household appliances. (operating conditions, assembly conditions, production costs, etc.) This puts forward higher requirements for the performance of adhesives.
Take polycarbonate as an example. Although it belongs to PC, it shows different surface properties and requires different adhesive products. How to bond different materials together reliably will also be a direction for future adhesive development.
