Method for washing shoe material with ultrasonic

Abstract

The invention relates to a method for washing a shoe material with ultrasonic, comprising the following steps of: (1) providing an ultrasonic washing machine which is provided with a liquid medicine trough, a clean water trough, a neutralization trough, a steam coil heating device, a transmission net and an oven, installing a pH electronic tester with the ultrasonic frequency of 28 kHz; (2) injecting an acidic finishing agent in the liquid medicine trough, injecting cleaning water finishing agent in the clean water trough, and injecting an alkaline finishing agent in the neutralization trough; and (3) placing the shoe material on the upper and lower transmission nets of the ultrasonic washing machine with the face to be processed facing downwards, thoroughly cleaning the shoe material through the high-pressure spray washing and high-frequency mechanical oscillation of the ultrasonic, and drying blanking. In the invention, acid and alkali processing and ultrasonic mechanical oscillation are adopted to ensure that the surface of the material is deoiled and separated from agents, thereby the purpose of cleaning the material is achieved. Compared with a traditional roughing process, the invention simplifies the operation process, reduces the cost, improves the cleaning efficiency and quality, reduces the labor intensity and has little noise and no dust or no toxicity.

Description

technical field [0001] The invention relates to a method for ultrasonically washing shoe-making materials, in particular to a method for degreasing rubber and EVA, releasing agent, and decontaminating the surface of materials. Background technique [0002] The current general practice for cleaning shoemaking materials is: 1. Use organic solvents such as toluene and benzene derivatives to degrease, release the mold, and decontaminate the surface of the material, so that the surface treatment of the material can meet the requirements of Bonding. Toluene and benzene derivatives in the use of this method are quite smelly and toxic treatment agents. This kind of organic solvent can enter the blood and accumulate. The human body has a long metabolism, and it is easy to suffer from occupational diseases after long-term exposure. 2. The surface is roughened. This method can also degrease rubber and EVA and release the molding agent. However, this method has low manual operation effi...

[0002] The current general practice for cleaning shoemaking materials is: 1. Use organic solvents such as toluene and benzene derivatives to degrease, release the mold, and decontaminate the surface of the material, so that the surface treatment of the material can meet the requirements of Bonding. Toluene and benzene derivatives in the use of this method are a very smelly and toxic treatment agent. This kind of organic solvent can enter the blood and accumulate. The human body has a long metabolism, and it is easy to suffer from occupational diseases after long-term exposure.

2. The surface is roughened. This method can also degrease rubber and EVA and release the molding agent. However, this method has low manual operation efficiency and scratches on the surface of the material. The vibration and noise of the roughing machine is large, and the roughing machine runs at high speed. There is a lot of dust, which is quite harmful to people and the environment.

Although the shoe industry has done a lot of research and experiments on shoe material cleaning, it has not yet found a good way to solve the problem of shoe material cleaning. Therefore, the market urgently needs an environmentally friendly and efficient shoe material cleaning method.
