Problems solved by technology

For a long time, my country has never conducted extensive research on the comprehensive utilization of crop bean shells. People use the peeled shells of beans and rice as waste and throw them away or burn them at will. This is not only a great waste of resources, but also has a negative impact on the environment. A lot of pollution, causing huge economic losses

Embodiment 1

[0023] Embodiment 1 preparation method, the steps are as follows:

[0024] 1) drying the harvested crop carob shells until the moisture content is 15%, and then putting them into a pulverizer and pulverizing them to 100 mesh;

[0025] 2) Take the ingredients in proportion, stir and mix the ingredients evenly, put them into a kneader, and knead at 150°C for 15 minutes;

[0026] 3) The mixed material after kneading is extruded and cooled by a twin-screw extruder.

Embodiment 2

[0027] Embodiment 2 preparation method, steps are as follows:

[0028] 1) drying the harvested crop carob shells until the moisture content is 10%, and then putting them into a pulverizer and pulverizing them to 200 mesh;

[0029] 2) Take the ingredients in proportion, stir and mix the ingredients evenly, put them into a kneader, and knead at 170°C for 12 minutes;

[0030] 3) The mixed material after kneading is extruded and cooled by a twin-screw extruder.

Embodiment 3

[0031] Embodiment 3 preparation method, steps are as follows:

[0032] 1) drying the harvested crop carob shells until the moisture content is 8%, and then putting them into a pulverizer and pulverizing them to 300 mesh;

[0033] 2) Take the ingredients in proportion, stir and mix the ingredients evenly, put them into a kneader, and knead at 130°C for 10 minutes;

[0034] 3) The mixed material after kneading is extruded and cooled by a twin-screw extruder.

Abstract

A synthetic material with high density, mechanical performance, insulation to heat and sound, resistance to fire, corrosion and ageing, and machinability is proportionally prepared from bean shell powder, plastic resin, calcium carbonate, flame-retarding agent, anti-ageing agent, lubricant and brightening agent through proportional mixing, kneading, dual-screw extruding out while shaping and cooling.

Description

technical field [0001] The invention relates to a synthetic profile of carob shells and a preparation method thereof, in particular to a synthetic profile of carob shells using post-harvest waste of crops and a preparation method thereof. Background technique [0002] As a by-product of agricultural production, carob husks are an important biological resource with large yield and wide distribution. The utilization technology of carob husks is to process the excess waste carob husks into another kind through various processing methods. available products. For a long time, my country has never conducted extensive research on the comprehensive utilization of crop bean shells. People use the peeled shells of beans and rice as waste and throw them away or burn them at will. This is not only a great waste of resources, but also has a negative impact on the environment. A lot of pollution has been caused, which has caused huge economic losses. It is a significant task before us to...
