The manufacturing method
of standard glue
1. Introduction

With the progress of science and technology and the development of chemical industry, the application of standard glue in the field of chemical production raw materials is more and more extensive. Standard glue has excellent performance and a wide range of uses, so its manufacturing method has attracted much attention. This paper will introduce the manufacturing method of standard glue in detail, including raw material preparation, mixing, plasticization, molding and other steps, in order to provide a useful reference for the production of chemical products.

2. raw material preparation

1. Natural rubber: Select high-quality natural rubber as the main raw material, requiring high gum content, less impurities, and uniform color.
2. Synthetic rubber: According to product performance requirements, suitable synthetic rubber can be used as auxiliary raw materials, such as styrene butadiene rubber, butadiene rubber, etc.
3. filler: commonly used filler calcium carbonate, clay, carbon black, etc., used to improve the strength and hardness of the compound.
4. Auxiliaries: such as vulcanizing agent, accelerator, antioxidant, plasticizer, etc., used to improve the processing performance and use performance of rubber.

3. mixing

will be prepared in accordance with a certain proportion of raw materials into the mixer, mixing. During the mixing process, it is necessary to control the temperature and time to ensure that the raw materials are fully mixed and evenly. After the end of mixing, the rubber material is taken out, tested and adjusted to meet the requirements of the production process.

4. plasticizing

plasticizing is to mix the good rubber through the extruder or open mill for plasticizing processing, so that it has a certain plasticity and fluidity. In the process of plasticizing, it is necessary to control parameters such as temperature, pressure and speed to ensure the quality of the rubber compound.

5. molding

molding is the plasticized rubber processed into the desired shape and size of the product. Commonly used molding methods include calendering, injection, extrusion, etc. In the molding process, it is necessary to control parameters such as temperature, pressure, and time to ensure the dimensional accuracy and surface quality of the product.

6. vulcanization

vulcanization is a cross-linking reaction of the molded rubber through the vulcanization equipment, so that it has a certain strength, hardness, wear resistance and other properties. During the vulcanization process, parameters such as temperature, time, and pressure need to be controlled to ensure the degree of vulcanization and product quality.

7. quality inspection and packaging
After the
vulcanization is completed, it is necessary to conduct a comprehensive quality inspection of the product, including the inspection of appearance, size, performance, etc. After passing the test, packaging is carried out to ensure the quality of the product during transportation and use.
Precautions for
8.

1. In the entire manufacturing process, it is necessary to strictly control the temperature, time, pressure and other parameters of each process to ensure product quality.
2. The selection and treatment of raw materials should meet the requirements of environmental protection to avoid environmental pollution.
3. In the production process, equipment maintenance and maintenance should be carried out regularly to ensure the normal operation of equipment and improve production efficiency.

9. conclusion The manufacturing method of

standard glue includes the steps of raw material preparation, mixing, plasticization, molding, vulcanization, quality inspection and packaging. In the entire manufacturing process, it is necessary to strictly control the parameters of each process to ensure product quality. At the same time, we should pay attention to the requirements of environmental protection and equipment maintenance to improve production efficiency and enterprise efficiency.
