Manufacture method of carbonization bamboo chopping block

Abstract

The invention relates to a method for manufacturing a carbonized bamboo chopping board, which is characterized in that bamboo as a raw material is subjected to light even carbonization and then the carbonized bamboo is processed into a chopping board. The method has the following advantages: the carbonized bamboo chopping board manufactured by the method is subjected to primary light even carbonization and secondary shaping, so that living spaces of insects and bacteria are radically eliminated, and the bamboo chopping board has good anti-corrosion and insect-proof functions; and because water absorbing functional groups such as hemicelluloses are recombined, the product has good physical property, is a real environment-friendly product, is not added with any chemical agent, does not contain any harmful substance, and does not generate any adverse influence on a human body, animal and environments during production, use and treatment of the used wastes. Through measuring the change degree of physical-mechanical properties of the carbonized bamboo chopping board, such as bending strength, elastic modulus, impact ductility, chordwise drying shrinkage property, radial drying shrinkage property, chordwise moisture expanding property and radial moisture expanding property, the best process conditions are determined, namely influential factors such as rate of temperature increase, carbonizing time and carbonizing temperature.

Description

A kind of manufacture method of carbonized bamboo chopping board technical field The invention relates to a method for manufacturing a carbonized bamboo cutting board, which belongs to the technical field of cutting board manufacturing. Background technique In daily life, chopping boards are needed in hotels, restaurants, and restaurants, as large as every family, and the bamboo and wooden chopping boards commonly used by people are low in cost, but due to the high sugar and moisture content in bamboo, it is difficult to use them. In addition to being susceptible to mildew and deterioration, cutting boards are also often eaten by some pests. After the cutting board is eaten by moths, there will be uneven spots and moths in mild cases. Although it can be used, it is not beautiful and the service life is not long. In severe cases, moth holes will form and cannot be used any more. There are also many ways to prevent moth, such as high-temperature treatment, paint treatment, ...

In daily life, chopping boards are needed in hotels, restaurants, and restaurants, as large as every family, and the bamboo and wooden chopping boards commonly used by people are low in cost, but due to the high sugar and moisture content in bamboo, it is difficult to use them. In addition to being susceptible to mildew and deterioration, chopping boards are also often eaten by some pests

After the cutting board is eaten by moths, there will be uneven spots and moths in mild cases. Although it can be used, it is not beautiful and the service life is not long. In severe cases, moth holes will form and cannot be used any more.

There are also many ways to prevent moth, such as high-temperature treatment, paint treatment, chemical treatment, etc. Although these treatment methods can achieve the purpose of moth prevention, these methods have their own disadvantages. The glucose group in the molecule will undergo a dehydration reaction, and its water-absorbing functional group hemicellulose will be reorganized, causing the cutting board to deform and affect the appearance, while the coating and chemical treatment will pollute the environment and be harmful to human health
