Manufacturing method of dry adhesive
I. Introduction
Dry adhesive is an important raw material in the production of chemicals and is widely used in adhesives, sealants, coatings and other fields. With the continuous development of science and technology, the manufacturing method of dry glue is also being improved and optimized. This paper will introduce a common manufacturing method of dry glue.
II. Materials and Methods
1. Materials
The main materials used to manufacture dry adhesives include polymers, solvents, crosslinking agents, fillers and so on. Among them, the polymer is the main component of the adhesive, which determines the basic properties of the adhesive; the solvent is used to adjust the viscosity and construction performance of the adhesive; the crosslinking agent is used to improve the adhesive's water resistance, heat resistance and other properties; and the filler is used to improve the mechanical properties of the adhesive and to reduce costs.
2. Manufacturing method
(1) Batching: add polymer, solvent, crosslinking agent, filler and other raw materials into the batching tank according to a certain proportion, and mix well.
(2) Grinding: Pour the mixture in the dosing tank into the grinder and grind it to a certain fineness.
(3) Adjusting: Pour the ground mixture into the adjusting tank, add certain catalysts and inhibitors, and adjust the parameters such as pH value and viscosity, so as to make it reach the required construction performance.
(4)Packaging：Put the modulated dry adhesive into the drum or bag for sealed packaging.
III. Results and Discussion
1. Results
Through the above manufacturing method, we can obtain a stable dry adhesive with good adhesive properties, water resistance, heat resistance and so on.
2. Discussion
In the manufacturing process of dry adhesive, the following issues need to be paid attention to:
(1) Reasonableness of the proportion of ingredients: different proportions of raw materials will have an effect on the performance of the dry adhesive, so it is necessary to carry out a reasonable proportion according to the specific needs.
(2) the fineness of grinding: the fineness of grinding will affect the adhesive properties and construction performance of the adhesive, so you need to control the parameters of the grinding machine to ensure that the grinding effect.
(3) Stability of adhesive mixing: In the process of adhesive mixing, it is necessary to control the dosage of catalyst and inhibitor, as well as pH value and viscosity and other parameters to ensure the stability of dry adhesive.
Four, conclusion
Through the above manufacturing method, we can get a dry glue with stable performance, which is suitable for various chemicals production fields. In the actual production process, the manufacturing method needs to be optimized and improved according to the specific needs in order to improve the production efficiency and product quality.
