The composition of the material of the meter box
The material used to make the low voltage cable branch box is a resin based composite. The main components of the cabinet are divided into ABS engineering plastics, polycarbonate transparent PC materials, DMC, SMC four materials injection molding, pressing. The composite material consists of two parts: a matrix-polyester resin; a reinforcing material (PC, SMC for short), so it is also called a transparent PC material, a fiber-reinforced polyester material. The transparent PC material and the fiber-reinforced unsaturated polyester are composite materials based on an unsaturated polyester resin. The two materials have insoluble, flame-retardant and recyclable characteristics. The latter material has incompatibility and non-recyclability. The physical structure is a three-dimensional network structure. These four materials have been modified by functional fillers and enhanced by special fibers. Become a high performance engineering material.
In developed countries such as Europe and the United States, this material has been widely used in the electrical field as early as a few decades ago.
Tape Measure is a commonly used tool in daily life. What you often see is the Steel Tape Measure, which is commonly used in construction and decoration, and is also one of the essential tools for the family. Divided into fiber tape measure, tape measure, waist measurement and so on. Luban ruler, Feng Shui ruler, and Wen Gong ruler are also steel tape measures.
