The raw material for most nonwovens is polypropylene, while the raw material for plastic bags is polyethylene. The two energy names are similar, but the chemical structures are very different. The chemical composition of polyethylene is quite stubborn and difficult to degrade, so plastic bags need 300 years to decompose. Next, I will introduce the environmental friendliness of non-woven fabric.
The chemical layout of polypropylene is not tenacious, and the molecular chain of nonwoven fabric is very redundant or broken, so it can be effectively degraded and enter the next cycle in a non-toxic form. A shopping bag will decompose within 90 days. And this shopping bag can be repeatedly operated more than 10 times, the abolition of the pollution level is only 10% of plastic bags.
1, the transplantation and transplantation of garden trees. Before the big trees and seedlings are put into the soil, you can put the non-woven fabric in the tree pit, then into the soil, and then put the nutrient soil into it. In this way, the survival rate of garden trees at the heel is high, and can retain water and fertilizer.
2、 greenhouse seedlings, open ground covered with floating surface in winter (25~30g/280cm). It prevents wind blowing and raises the temperature. On one side of the seedbed, it is compacted with soil, and on the other side, it is compacted with bricks and soil. Bamboo pieces or thick wire can also be used to make a small arch, which is covered with non-woven fabric and compacted with bricks or soil to keep the insulation in place. Covered vegetables and flowers need more sunlight so that they can be uncovered in the morning and covered at night. Covering a floating surface increases the temperature 10 cm from the surface by about 2 and increases the ground temperature by 1 to 2°C. Covered vegetables can be marketed 5~7 days earlier and the yield can be increased by about 15%.
3、For canopy use. Set up a non-woven fabric as a roof in greenhouses and greenhouses, the distance between the roof and the plastic greenhouse film is 15~20 cm; form an insulation layer, which can make the temperature inside the greenhouse increase by 3~5 open during the day and close at night, the sandwich needs to be closed tightly to be effective.
4, small arches outside the cover (specifications 80 ~ 100g/280 cm), instead of insulation, grass curtain, saving 20% of the cost, service life greatly extended; you can also cover a layer of non-woven fabric and plastic film on the small arches, which can raise the temperature 5 ~ 8 ℃.
5, for shading sunlight. With non-woven fabric, cover the seedbed directly, cover in the morning and uncover at night, which can effectively improve the neatness and integrity of seedlings. Small and medium-sized seedlings of vegetables and flowers in summer can be covered directly on the seedlings.
6、Before the cold wave comes, tea, flowers and other crops susceptible to frost damage can be directly covered with non-woven fabric, which can effectively reduce frost damage loss.
To sum up, the material of non-woven fabric is still very good and can be used for transplanting garden trees and fake planting, which has many advantages in greenhouse and outdoor nursery in winter.
