A power source that uses visible energy to generate visible light is called an electric light source. The invention of an electric light source promotes the construction of an electric device. The electric light source has high conversion efficiency, stable power supply, convenient control and use, safe and reliable, and can easily count the energy consumption by the meter. Therefore, it has been popularized for more than one hundred years after its publication. It not only becomes a necessity for human daily life, but also plays an important role in industry, agriculture, transportation, and national defense and scientific research.
Adhesive modified rosin resin(pentaerythritol resin) is specially designed for hot-melt adhesive industry,the advantage is light color,high softning point,viscosity and heat resistance.Particularly applicable to EVA glue,hot melt glue,hot melt coating area,ect.Resin adhesive products can be used on almost any type of material, including metal, glass, plastic, ceramics, and stone. They are widely used in the construction industry to join various building materials, and are also used in the production of composite products such as fiberglasspanels or doors. Due to their high level of moisture-resistance, resin adhesives also play an important role in the marine industry, and are one of the primary bonding agents used in boat construction. These adhesives are also used in the aeronautical industry because of their high strength-to-weight ratio.
