Internal steel tube structure, the exterior is made of plastic PVC flower box. Some flower boxes are lined with impervious geotextiles. Water holes are usually left at the bottom. Advantages: beautiful appearance, aging resistance, corrosion resistance, long service life, durable. PVC or PVC, the English abbreviation of PVC (Polyvinyl chloride), vinyl chloride monomer (vinyl chloride monomer, VCM) such as peroxide, azo compound initiator; Or polymerized under the action of light and heat according to the mechanism of free radical polymerization. Vinyl chloride homopolymer and vinyl chloride copolymer are known as vinyl chloride resin. The material is an amorphous material. PVC materials are often used in the actual use of stabilizers, lubricants, auxiliary processing agents, color, impact agent and other additives. Non-flammability, high strength, weather resistance and excellent geometric stability. PVC is resistant to oxidants, reducing agents and strong acids. However, it can be highly oxidized and is not suitable for contact with aromatic and chlorinated hydrocarbons. PVC material is polyvinyl chloride, it is one of the largest production of plastic products in the world, cheap, widely used, polyvinyl chloride resin for white or light yellow powder, can not be used alone, must be modified. PVC is amorphous structure of white powder, less branching, poor stability to light and heat. Different additives can be added according to different USES, PVC plastics can present different physical properties and mechanical properties. A variety of hard, soft and transparent products can be made by adding plasticizer in PVC resin. It is to use model wood commonly now much, model wood product has moistureproof tall environmental protection, it is a kind of low carbon that has development prospect extremely, green, can cycle can regenerate zoology to model wood material, it is the environmental protection green material that the country admits. And plastic wood stability is very good, the product anti-aging, waterproof, moisture-proof, mildew proof, anticorrosive, moth-eaten, termite proof, effective flame retardant, weather resistance, anti-aging and heat preservation and heat insulation energy-saving, can be used for a long time in the outdoor environment with large changes in climate morphology, and not deterioration, not embrittlement, performance. For example, for some outdoor products, for large outdoor projects, the service life of this material can reach 20 years.
we are manufacture of PVC planters and WPC planters in China.
