The manufacturing method
of leather slurry
1. Introduction

leather slurry is an important part of the field of chemical production raw materials, widely used in leather processing industry. This article will introduce the manufacturing method of leather slurry in detail, including raw material selection, ratio, mixing, grinding, adjustment and other steps, in order to provide readers with a useful reference.

2. Raw Material Selection and Proportioning

1. Raw Material Selection: The main raw materials of leather slurry include collagen, starch, acrylic emulsion, etc. When selecting raw materials, we should pay attention to their quality, stability and operability.
2. Ratio: According to the requirements of leather processing and the needs of slurry performance, the ratio of each raw material is reasonably determined. In general, collagen accounts for a relatively large proportion, starch and acrylic emulsion accounts for a relatively small proportion.

3. Mixing and Grinding

1. Mixing: The selected raw materials are put into the mixing equipment according to the ratio, and are fully stirred and mixed to ensure the uniform distribution of the raw materials.
2. Grinding: The mixed slurry is sent to the grinding equipment for fine grinding to improve the fineness and uniformity of the slurry.

4. performance adjustment and optimization

1. pH value adjustment: according to the requirements of leather processing, adjust the pH value of the slurry to the appropriate range, in order to ensure the quality of leather and processing effect.
2. Additive addition: according to the need, can add the right amount of preservatives, antioxidants, fillers and other additives to improve the performance and stability of the slurry.

5. quality inspection and storage

1. quality inspection: the manufacture of good quality inspection of leather pulp, including viscosity, solid content, pH value and other indicators of detection, to ensure that the quality of pulp in line with the relevant standards.
2. Storage: Store the qualified slurry in a sealed container and place it in a cool and dry place, avoiding direct sunlight and high temperature environment.
Precautions for
6.

1. In the manufacturing process, the quality and ratio of each raw material should be strictly controlled to ensure the stability of slurry performance.
2. During the mixing and grinding process, the equipment should be kept clean to avoid impurities mixing and affecting the quality of the slurry.
3. In the process of performance adjustment and optimization, various parameters should be adjusted flexibly according to the actual situation to meet different leather processing needs.

7. Conclusion

This paper introduces the manufacturing method of leather slurry in detail, including raw material selection, ratio, mixing, grinding, performance adjustment and optimization. By mastering these key steps, leather slurry with stable quality and excellent performance can be produced, which provides strong support for the leather processing industry. In the actual production process, the methods described in this paper should be used flexibly according to specific needs and conditions to achieve the best production results.
