Abstract

The invention discloses a manufacturing process of an environment-friendly pencil. The manufacturing process comprises the following preparation steps that raw materials are processed; adhesive is prepared; materials are mixed; a pencil casing is formed; the pencil casing is primarily treated; secondary treatment is carried out on the pencil casing; tertiary treatment is carried out on the pencilcasing; and disinfection is carried out. According to the manufacturing process of the environment-friendly pencil, corn straw and barnyard grass which are common in rural areas are adopted as the rawmaterials for preparing a pencil casing plate, so that waste of other resources in pencil production is greatly reduced, and the purpose of saving energy is achieved; and the waste of social resources can be effectively reduced, the price of the production raw materials is low so that the production cost of pencil manufacturers can be greatly reduced, and the purposes of environmental protectionand energy conservation can be remarkably achieved.

Description

technical field [0001] The invention relates to the technical field of pencil production, in particular to a production process of an environment-friendly pencil. Background technique [0002] Traditional wooden pencils have a history of more than 300 years, and the current consumption in the world reaches more than 10 billion. my country's annual output of pencils is about 7 billion, accounting for two-thirds of the world's total output. It is the world's largest producer of pencils and is exported to many countries. Although a large amount of export has exchanged a lot of foreign exchange for the country, it has also paid a huge price. Due to long-term over-harvesting of high-quality basswood used to produce pencils, not only the ecological environment has been severely damaged, but the timber output has also decreased. decrease year by year. With the implementation of the national natural forest protection project, the timber plan has been lowered, and the originally ra...
