Manufacturing method
of rosin
rosin is a common chemical production raw material, widely used in paint, rubber, printing ink and other fields. This article will introduce the manufacturing methods of rosin, including raw material preparation, processing equipment, production technology, product quality control and so on.

1. Raw Material Preparation The raw material for

rosin is mainly turpentine, which is a viscous liquid collected from pine trees. Before the manufacture of rosin, the rosin needs to be treated to ensure its quality and purity. First, you need to collect the rosin in a container and let it stand for a period of time to allow it to settle naturally and remove impurities and moisture. Then, the pine resin is heated to melt, and impurities and solid particles therein are filtered out to obtain relatively pure pine resin.

2. processing equipment

rosin manufacturing needs to use some special processing equipment, including melting tank, reaction kettle, filter, cooler and so on. These devices need to have high temperature resistance, corrosion resistance and other characteristics to ensure the safety and stability of the production process.

3. production process
The manufacturing process of
rosin mainly includes the following steps:

1. Melting: Put the processed rosin into a melting tank, heat and melt it to make it a liquid with better fluidity.

2. catalytic reaction: after the melting of the resin liquid into the reaction kettle, adding a certain amount of catalyst, control a certain temperature and pressure, so that the resin catalytic reaction, the formation of rosin and turpentine.

3. Separation: Through the cooler and filter, the rosin and turpentine oil generated by the reaction are separated to obtain relatively pure rosin products.

4. Molding: The separated rosin liquid is molded to make it a solid product of a certain shape and specification.

4. product quality control

In order to ensure the quality of rosin products, it is necessary to strictly control the quality of all links in the production process. First of all, it is necessary to test the quality and purity of the raw material rosin to ensure that it meets the production requirements. Secondly, in the production process, it is necessary to strictly control the reaction temperature and pressure, as well as the amount and type of catalyst, to ensure that the resulting rosin products meet the specified quality standards. Finally, quality inspection and performance testing of the finished product is required to ensure that it meets the relevant standards and requirements.

5. environmental protection and safety production

rosin manufacturing process will produce certain waste gas, waste water and solid waste and other pollutants, so it is necessary to carry out environmental protection and safety production. In the production process, it is necessary to take effective measures to reduce waste emissions and environmental pollution. At the same time, it is necessary to strengthen production safety management, ensure that production equipment and operations comply with relevant regulations and standards, and ensure the safety and health of employees and surrounding residents.

In short, the manufacturing method of rosin needs to take into account many aspects such as raw material preparation, processing equipment, production process, product quality control, environmental protection and safe production to ensure product quality and production safety and environmental protection.
