Manufacturing Methods of Viscose Adhesives
I. Introduction
Viscose adhesives play an important role in the production of various chemicals, especially in the fields of composites, building materials, textiles and packaging industries, etc., which are widely used. Therefore, it is of great significance to study and master the manufacturing method of viscose agent to improve product quality and production efficiency. In this paper, we will introduce the manufacturing method of viscose agent in detail, including raw material selection, formulation design, production process and quality control.
II. Selection of raw materials
1. Main body material: the main body material of the adhesive agent is usually polymer compounds, such as polymers, resins and so on. When choosing the main material, you need to consider its bonding performance, weather resistance, heat resistance, cold resistance and other performance indicators.
2. Additives: In order to improve the performance of the adhesive, it is necessary to add some auxiliary materials, such as curing agents, accelerators, fillers, toughening agents and so on. Selection of additives need to be screened according to the specific use and performance requirements of the viscose agent.
Three, formula design
The formula design of the adhesive needs to consider the following aspects:
1. The proportion of the main material and additives: the need to determine the appropriate ratio according to the performance indicators and experimental data.
2. Compatibility between additives: need to ensure that the additives do not chemically react with each other or interfere with each other, affecting the performance of the adhesive.
3. Viscosity adjustment: by adjusting the proportion of each component in the formula, the viscosity of the adhesive can be controlled to meet the requirements of different construction conditions.
4. Production process
The production process of adhesive mainly includes the following steps:
1. dosing: add raw materials and additives to the mixing equipment according to the formula ratio.
2. Stirring and mixing: Mix the components well through the mixing equipment.
3. Grinding: For adhesives that need to be improved in fineness, they need to be ground to obtain a finer colloid.
4. Defoaming: Remove the air bubbles in the adhesive by vacuum defoaming or mechanical defoaming to improve its usability.
5. Packaging: Pack the prepared viscose agent into appropriate packaging containers, and marking and storage.
5. Quality control
In order to ensure the stable and reliable quality of the viscose agent, it is necessary to carry out comprehensive quality control, including the following aspects:
1. Quality control of raw materials: carry out quality inspection of raw materials to ensure that they comply with the relevant standards and regulations.
2. Quality control of production process: comprehensive monitoring of the production process to ensure that the production process parameters and product quality meet the predetermined requirements.
3. Finished product inspection: carry out performance testing on the produced adhesive, including bond strength, weather resistance, heat resistance, cold resistance and other indicators, to ensure that the product meets the relevant standards and customer requirements.
VI.CONCLUSION
The manufacturing method of adhesives involves a number of links and factors, including raw material selection, formula design, production process and quality control. In order to improve the performance and production efficiency of adhesives, these factors need to be considered comprehensively and optimized. At the same time, continuous research and exploration of new manufacturing technologies and methods is also an important way to promote the development of the viscose agent industry.
