" one
The invention relates to agriculture and is intended to combat pests.
A known package for pesticides, including bonded on the edges of the sheets of gas-permeable non-woven
of the material
The known package is made of paper — a material containing randomly arranged natural fibers with a wide variation in thickness, i.e. having a wide range of titer. As a result, the size of the cells (pores) of the material used is too different, which leads either to an incomplete use of gases or to a loss of powder. The paper is easy to soak and becomes impermeable to gases.
The aim of the invention is to increase the utilization rate of pesticides.
The goal is achieved by the fact that in the package for phosphine pesticides, the nonwoven material is made of synthetic fibers with a titer of 1.5-2 and has cells of 10-12 microns.
The drawing schematically shows a package, a general view.
The package for phosphine pesticides is made of a continuous tape of nonwoven material, bent so that the package contains the bottom 1 and the top 2
8552 2
side, with / bottom side 1 is somewhat longer than the top.
The tape is made of synthetic fibers, such as polyamide, with a titer of 1.5-2. This thickness of the fibers provides in the material of the cell (pores) with a size of 10-12 microns. On the side edges, sides 1 and 2 are welded by seams 3 using the thermal or ultrasonic method. It is possible to manufacture bags with several pockets, and intermediate seams are welded using the same methods.
The bag is filled with phosphine pesticide powder, after which the projecting edge of the bottom side 1 is bent onto the top side 2 and sealed. In this form, pesticide bags are placed in the room with products to be fumigated.
When decomposing a pesticide, gaseous poisonous products easily pass through the cells and poison pests. At the same time, the dusty decomposition products are delayed in the bag.
The use of these packages saves 5-10% pesticides. These bags have increased strength and are characterized by a very low moisture content, thereby preventing premature unwanted gas formation during pro- lection. filling up.
