Straw flowerpots not only have the advantages of light weight and easy handling of wooden flowerpots, but also have the advantages of bright colors and many styles of plastic flowerpots. At the same time, they also have the advantages of good air permeability and easy growth of flowers and plants, and also take into account the advantages of gorgeous and noble appearance of ceramic flowerpots. In addition, the most outstanding advantage of plant fiber flowerpot is that it can be biodegradable after being discarded, and it does not produce solid waste and pollute the surrounding environment, which meets the requirements of circular economy and the national Twelfth Five-Year Plan.
Principle:
The invention relates to a method for manufacturing a flowerpot by using waste straw board sand powder (rice husk, rice straw, wheat straw, corn straw, cotton straw, sawdust, bamboo shavings and other crop straws or other plant straws), which comprises the following steps: adding dried straw board sand powder and auxiliary materials into a high-speed mixer and uniformly stirring; At the same time, the adhesive and the auxiliary agent are evenly stirred; Then adding a composite curing agent to adjust the pH value of the glue solution to 4.5-6.0; Spray the glue solution into the mixed material and mix it evenly; Dry material; Molding. Advantages: it replaces raw materials such as soil, plastic, wood or other plant fibers, is cheap and good, turns waste into treasure, saves resources, and has good drainage and air permeability. There is no need to turn over the pot when transplanting, and the nutrient pot naturally decomposes into humic acid organic fertilizer in the soil. The flowerpot can freely fall on the concrete floor with a height of 1m without being damaged. After 66 hours of xenon lamp irradiation, the appearance changes greatly, the mildew phenomenon is serious, the surface is rough and there are a few cracks, which shows that it is a biodegradable pot.
