Description
Technical Field
The application relates to the technical field of straw production processes, in particular to a river thatch straw and a manufacturing process thereof.
Background
The suction pipe is mainly used for drinking beverages in a cup and sucking bone marrow of cooked animal long bones, and the suction pipe is used for sucking partial air against the suction pipe when in use by applying the atmospheric pressure principle, so that the pressure in the suction pipe is reduced, and the atmospheric pressure can force liquid in the suction pipe to rise in order to balance the air pressure. When the suction stops, the liquid in the tube drops and the pressure returns to equilibrium. This is the wonderful principle and application of the straw.
The straw can be divided into paper straw, PLA straw and plastic straw according to the material. Among the four types of straws, the PLA straw can be naturally degraded only in a specific environment, and can be completely degraded only in hundreds of years generally; the plastic straw can be degraded in natural environment for hundreds of years, and the degraded plastic straw still has destructiveness to the environment and great harm to human bodies; the paper straw can be completely degraded in a natural environment for dozens of days, but the paper straw has the defects that a large amount of wood needs to be consumed, a large piece of forest is damaged, the paper straw is poor in waterproofness and unstable in quality, is easy to be soaked in soft water, and is poor in user experience, and the paper straw can collapse and become soft after being soaked in liquid for more than half an hour, even can be directly decomposed in the liquid, so that the sanitation and safety of food are affected.
The cogongrass rhizome is named as winter cogongrass rhizome, the gerbera elata, annual cogongrass plants like dampness, slightly sweet in taste, flat in nature, free of peculiar smell, non-toxic, easy to degrade, capable of being planted in a barren slope, wild lands and valleys and harvested in autumn and winter. The Festuca arundinacea is propagated vegetative propagation mainly by rhizome, and can also be propagated by seeds, and is usually propagated into a pure community in a large area. The shoveling is extremely labor-consuming, namely 'several shovels are not removed, the stem is broken and the root grows again', unless the root is thoroughly and deeply turned over, all the rootstocks are picked out and transported to the field for destruction, otherwise the rootstocks survive in case of rain or water and soil, so the resource utilization of the festuca arundinacea is also a big problem at present.
