SMC and BMC are composite materials.
The BMC material is a mass molding compound. The main raw materials are short cut glass fiber, unsaturated resin, filler) and various additives, which are fully mixed into a pellet like prepreg. Due to its excellent electrical properties, mechanical properties, heat resistance, chemical corrosion resistance, and adaptability to various molding processes, BMC can meet the performance requirements of various products, and is widely used in automobile manufacturing, railway transportation, building accessories, mechanical and electrical products and other fields.
SMC composite material is sheet molding compound. The main raw materials are long glass fiber, unsaturated resin, low shrinkage additives, fillers and various additives. SMC composite materials and SMC molded products have excellent electrical insulation, mechanical properties, thermal stability, chemical corrosion resistance. So SMC products are widely used. Now the trend is that SMC composites will eventually replace BMC materials.
At this stage, the tree protection boards we use are all made of BMC materials, because there are many big and small holes on the tree protection boards, SMC materials are sheet, the machine molding is not easy to separate, and it takes time, so the price will rise. According to the use environment of the tree protection board, it is suitable to use BMC materials, both in terms of quality and price.
Composite material also has a remarkable feature: it has the function of natural anti-theft. The material itself has no secondary use value, which greatly reduces the phenomenon of stolen tree protection boards.
The function of tree gtating: to protect trees and prevent soil erosion, the seepage holes around can keep the root soil loose, and the big holes around can be equipped with ground lamps to make the night of the city better.
To love trees is to love our homes.
