The excellent physical and mechanical electrical and electrical insulation properties of epoxy resins, the bonding properties with various materials, and the flexibility of their use processes are not possessed by other thermosetting plastics. Therefore, it can be made into coatings, composite materials, casting materials, adhesives, molding materials and injection molding materials, and has been widely used in various fields of the national economy.
Coating application
The application of epoxy resin in coatings accounts for a large proportion, and it can be made into various varieties with different characteristics and purposes. Its commonalities:
1. Excellent chemical resistance, especially alkali resistance. 2. The paint film has strong adhesion, especially to metal.
3. Has good heat resistance and electrical insulation.
4. The paint film has good color retention.
However, the weather resistance of bisphenol A type epoxy resin coating is poor, and the paint film is not easy to be powdered and lost in the outdoor. It is not suitable for outdoor use paints and high decorative paints. Therefore, epoxy resin coatings are mainly used as anti-corrosion paints, metal primers, and insulating paints, but coatings made of heterocyclic and alicyclic epoxy resins can be used outdoors.
Adhesive use
Epoxy resins are not only poor adhesion to polyolefins and other non-polar plastics, but also various metal materials such as aluminum, steel, iron, copper; non-metal materials such as glass, wood, concrete, etc.; and thermosetting plastics such as phenolic , ANJI, unsaturated polyester, etc. all have excellent adhesive properties, so it is said that WAN can glue. Epoxy adhesives are important types of structural adhesives.
Electronic appliances
Due to its unique advantages such as high insulation performance, large structural strength and good sealing performance, epoxy resin has been widely used in the insulation and packaging of high and low voltage electrical appliances, motors and electronic components, and has developed rapidly. Mainly used for: Pouring of electrical and motor insulation packages. Such as electromagnets, contactor coils, transformers, dry-type transformers and other high and low voltage electrical appliances as a whole sealed insulation package manufacturing. In the electrical industry, Kuai has developed rapidly. From atmospheric casting, vacuum casting has evolved to automatic pressure gel forming.
Here are all MAKITA power tools and the designated carbon brushes,motor brushes, electric brushes, motor brushes, electric motor brushes or simply brushes.
For each power tool, there are usually two carbon brushes to choose from: With automatic stop and without automatic stop. Carbon brushes with automatic stop have a spring through the length of the carbon brush. When the carbon brush wears out, the spring gets released, the current to the carbon brush gets interrupted and your power tools switches off at once. The advantage: No additional wear and tear to your power tool. Carbon brushes without automatic stop do not stop functioning at once, but performance of your power tool will detoriate rapidly. Although handy as a warning sign, this usually isn't very beneficial to your power tool.
