Problems solved by technology

[0002] At present, bamboo shoot shells are dumped nearby as a bulk waste of the bamboo shoot processing industry, making the discarded bamboo shoot shells pile up in the mountains and rivers, and a large number of bamboo shoot shells will pollute the mountains and rivers after decay, which will threaten the surrounding water and air. At present, there are few studies on the utilization of bamboo shoot shells, mainly focusing on degumming to make textile fiber materials, extracting flavonoid antioxidants, fermenting animal feed, and using modified bamboo shoot shells as adsorbents for metal ions. Therefore, bamboo shoot shells As a renewable resource, its fibrous tissue is long and bamboo shoot shells have high longitudinal strength. It is a good fiber reinforced material and needs to be used in more aspects to prevent further harm to the environment.
On the other hand, there are mainly the following types of flower pots on the market: ceramic flower pots, plastic flower pots, wooden flower pots, plastic degradable flower pots, etc. Among them, ceramic flower pots consume a lot of energy, are heavy, and are easily broken; Pots are not easy to degrade or even non-degradable, which will cause harm to the environment; wooden flowerpots are easy to decay and damage, which makes the cost of use too high; plastic degradable flowerpots have a long degradation cycle under natural conditions and can only be degraded to a certain extent

Embodiment 1

[0015] Embodiment 1: take bamboo shoot shell as main raw material, make bamboo shoot shell degradable flower pot, finished product flower pot size is upper mouth outer diameter 150mm, lower mouth outer diameter 115mm, outer height 130mm, wall thickness 2mm, comprises the following steps successively:

[0016] 1) Cut off the part of the top of the bamboo shoot shell whose thickness is less than 0.45mm. After pruning, the length of the bamboo shoot shell is 100-350mm, and the thickness of the base is 1.45-1.75mm. Clean the surface of the bamboo shoot shell to remove the impurities on the inner and outer surfaces and the fluff on the outer surface ;

[0017] 2) The cleaned bamboo shoot shells were softened and flattened, that is, after hydrothermal softening treatment in a constant temperature water bath at 80°C for 6 hours, stress grooves were set up on the inner surface along the fiber direction, so that the bamboo shoot shells became expanded sheet materials, and the stress Th...

Embodiment 2

[0021] Embodiment 2: take bamboo shoot shells as the main raw material, make bamboo shoot shells and make degradable flower pots, the finished flower pot size is the outer diameter of the upper mouth 150mm, the outer diameter of the lower mouth 115mm, the outer height 130mm, and the wall thickness 2mm, including the following steps in turn:

[0022] 1) Cut off the part of the top of the bamboo shoot shell whose thickness is less than 0.45mm. After pruning, the length of the bamboo shoot shell is 100-350mm, and the thickness of the base is 1.45-1.75mm. Clean the surface of the bamboo shoot shell to remove the impurities on the inner and outer surfaces and the fluff on the outer surface ;

[0023] 2) The cleaned bamboo shoot shells were softened and flattened, that is, after hydrothermal softening treatment in a constant temperature water bath at 60°C for 6 hours, stress grooves were set up on the inner surface along the fiber direction, so that the bamboo shoot shells became exp...

Abstract

The invention relates to a method for manufacturing a degradable flower pot with bamboo shoot shells. The method comprises the following processes: (1) bamboo shoot shells with certain sizes are subjected to a surface cleaning treatment, wherein impurities on the inner and outer surfaces are removed, and the fluffs on the outer surfaces are removed; (2) the bamboo shoot shells are subjected to a softening and flattening treatment and an NaOH solution treatment; (3) an adhesive is applied on the bamboo shoot shells, and the bamboo shoot shells are assembled into a blank; and (4) wet mold-pressing is carried out, such that the flower pot is obtained. The method has the following advantages: the degradable flower pot manufactured with the bamboo shoot shells has a low price; with the process, waste is turned valuable; in soil, the flower pot can be biologically degraded into nutrients for plants, and does not harm the environment; during an application process, repotting is not needed, and the plant can be transported with the flower pot. The flower pot is especially suitable for seedling raising, and can be used in cultivating various soil culture plants. Also, natural texture of bamboo shoot shells are maintained on the flower pot.

Description

technical field [0001] The present invention relates to bamboo shoot shells as the main raw material, through surface cleaning treatment, softening and flattening treatment, NaOH solution treatment, application of adhesives, formation of blanks, wet molding and other technologies to make bamboo shoot shell degradable flower pots, which belong to degradable flower pots. The technical field of degradable flowerpot manufacture. Background technique [0002] At present, bamboo shoot shells are dumped nearby as a bulk waste of the bamboo shoot processing industry, making the discarded bamboo shoot shells pile up in the mountains and rivers, and a large number of bamboo shoot shells will pollute the mountains and rivers after decay, which will threaten the surrounding water and air.
