Manufacturing method of leather slurry
I. INTRODUCTION
Leather slurry is an important part in the field of raw materials for chemical production, and is widely used in the leather processing industry. In this paper, the manufacturing method of leather slurry will be introduced in detail, including the steps of raw material selection, proportioning, mixing, grinding and adjustment, in order to provide readers with useful reference.
II, raw material selection and proportioning
1. Raw material selection: the main raw materials of leather slurry include collagen, starch, acrylic emulsion and so on. When choosing raw materials, should focus on its quality, stability and operability.
2. Proportioning: according to the requirements of leather processing and slurry performance needs, reasonably determine the proportion of each raw material. In general, collagen accounts for a larger proportion, starch and acrylic emulsion accounts for a smaller proportion.
Three, mixing and grinding
1. Mixing: put the selected raw materials into the mixing equipment according to the proportion, stir and mix thoroughly to ensure that the raw materials are evenly distributed.
2. Grinding: Send the mixed slurry into the grinding equipment for fine grinding treatment to improve the fineness and uniformity of the slurry.
Four, performance adjustment and optimization
1. pH value adjustment: according to the requirements of leather processing process, adjust the pH value of the slurry to the appropriate range, in order to ensure the quality of leather and processing effect.
2. Additives additive: according to the need, can add appropriate amount of preservatives, antioxidants, fillers and other additives, in order to improve the performance and stability of the slurry.
V. Quality inspection and storage
1. Quality inspection: quality inspection of manufactured leather slurry, including viscosity, solid content, pH value and other indicators of the test, to ensure that the quality of the slurry meets the relevant standards.
2. Storage: Deposit the tested slurry in a sealed container and place it in a cool and dry place, avoiding direct sunlight and high temperature environment.
VI. Precautions
1. In the manufacturing process, the quality and proportion of each raw material should be strictly controlled to ensure the stability of slurry performance.
2. In the process of mixing and grinding, the equipment should be kept clean to avoid impurity mixing and affecting the quality of slurry.
3. In the process of performance adjustment and optimization, the parameters should be flexibly adjusted according to the actual situation to meet different leather processing needs.
7. Conclusion
This paper describes in detail the manufacturing method of leather slurry, including raw material selection, proportioning, mixing, grinding, performance adjustment and optimization steps. By mastering these key steps, leather slurry with stable quality and excellent performance can be manufactured to provide strong support for the leather processing industry. In the actual production process, according to the specific needs and conditions, should be flexible to use the methods described in this paper, in order to achieve the best production results.
