Environmental protection of non-woven fabric

The chemical configuration of polypropylene is impatient, the molecular chain of non-woven fabric is disorderly broken, and it is generally effectively decomposed. In the non-toxic form, it is recycled to the following situations, and a non-woven shopping bag is roughly decomposed within 90 days. In addition, the non-woven shopping bag can be operated more than 10 times, and the pollution degree of the abolished situation is also 10% of that of the plastic bag.

1. Transplanting and temporary planting of garden trees. Before temporarily planting large trees and small seedlings, lay non-woven fabrics on the tree holes, and then lay nutrient soil. The survival rate of garden trees is high, which can maintain water and fertilizer.

2. In winter, it is covered with floating surface (specification: 25-30g / 280cm) in greenhouse and open field. It can prevent wind blowing and increase the temperature. One side of the seedbed is fixed with non-woven fabric with soil, and the other side is fixed with brick and soil. The small arch is made of bamboo or thick iron wire, and the non-woven fabric is covered on it. It can also be fixed around with brick or soil for thermal insulation. The vegetables and flowers need to be covered. They should be exposed to the sun in the morning and covered in the evening. With the floating roof cover, the temperature 10 cm away from the ground surface can be increased by about 2 ℃, the ground temperature can be increased by 1-2 ℃, and the covered vegetables can be put on the market 5-7 days in advance, and the output can be increased by about 15%.

3. Used as a ceiling. Non woven fabrics are paved in greenhouses and plastic greenhouses as ceilings. The film spacing between ceiling and plastic shed is 15-20cm; The formation of insulation layer can increase the temperature in the shelf by 3-5 ℃. Open during the day and close at night. The compartment must be closed properly to be effective.

4. Cover the small arch outside the door (specification: 80-100g / 280cm) instead of straw curtain for thermal insulation, which saves 20% of the cost and greatly prolongs the service life compared with straw curtain; The small arch can also be covered with non-woven fabric and plastic film to increase the temperature by 5-8 ℃.

5. Used to block sunlight. Directly covering the seedbed with non-woven fabric, covering in the morning and uncovering in the evening can effectively improve the quality of neat and whole seedlings. Vegetables, flower seedlings and medium seedlings can be directly covered on the seedlings in summer.

6. Before the cold current, directly covering tea, flowers and other crops vulnerable to freezing injury with non-woven fabric can effectively reduce the loss of freezing injury. To sum up, the material of Nonwovens in nonwovens is still very good, which can be used for garden tree transplantation and artificial planting. It has many advantages in greenhouse and open seedling raising in winter.
