Method of manufacturing large craft sculpture by employing abandoned cotton plant stems

Abstract

The invention discloses a method of manufacturing a large craft sculpture by employing abandoned cotton plant stems. The method comprises the steps as follows: (1) raw materials are prepared; (2) the abandoned cotton plant stems are pulverized to have the required lengths; (3) the pulverized cotton plant stems in the step (2) are mixed with starch, talc, sodium hydroxide and water according to a ratio, and the mixture is uniformly stirred for 3-30min; (4) the mixture is put in an extruder with the rotating speed of a charging rod being 25r / min and the rotating speed of a discharging rod being 32r / min, and a new raw material is extruded out; (5) the new raw material in the step (4) is injected to a sculpture mould and compacted, a high-temperature gas is supplied, and maintenance for 30-50min is carried out; (6) demoulding, smooth polishing, dust removal and cleaning are carried out; (7) the surface of a sculpture is coated with gold powder or a surface decoration layer; and (8) the sculpture is dried and warehoused. The method has the advantages that the abandoned cotton plant stems are used fully, wasting of limited resources and environmental pollution arising from incineration are avoided, the possibility of deforestation is reduced, ecological and limited green vegetation is protected, and the possibility of hazy weather is reduced.

Description

technical field [0001] The invention relates to the technical field of waste utilization, in particular to a method for making large-scale craft sculptures by using waste cotton plant stalks. Background technique [0002] Now after the cotton is harvested, the remaining cotton plant stalks are discarded by the farmers. Basically, they are burned or rotted naturally. If a large area of ​​cotton planting area like Xinjiang is burned, there will be smoke everywhere. It pollutes the environment, produces smog, and deteriorates the air. At the same time, effective resources are not fully recycled to maximize their value. Contents of the invention [0003] The purpose of the present invention is to manufacture a method for recycling waste cotton plant stalks, so as to maximize the utilization of effective resources and maximize their value, so that various large-scale industrial sculptures can be made to beautify the environment. [0004] The present invention is a kind of meth...

[0002] Now after the cotton is harvested, the remaining cotton plant stalks are discarded by the farmers. Basically, they are burned or rotted naturally. If a large area of ​​cotton planting area like Xinjiang is burned, there will be smoke everywhere. It pollutes the environment, produces smog, and makes the air worse. At the same time, effective resources are not fully recycled to maximize their value.
