In recent years, with the popularity of domestic automata, single-component adhesives independently researched and developed in China are also increasingly concerned and used by enterprises. Enterprises are more concerned about the quality and use cost of adhesives matching with the process while understanding the automation machine.

As the saying goes: "clever housewife cook without rice", even if the advanced and stable automation equipment if there is no high match with the process of adhesive will not be able to achieve automated production.
1. According to the use of single component adhesive in flap disc automatic machine, it can be classified as the following requirements:
In order to control the precise amount of adhesive, there is a relatively high demand for the adhesive viscosity, which must be unified and stable. The selection of raw materials must be of high quality, and higher production technology is needed to ensure the uniformity and unity of the viscosity.
2, Flap disc automaton production requirements are in constant temperature around 20 degrees, but few can satisfy the conditions to the current domestic customers, in order to make the product quality to achieve consistency, equipment more stable production, the adhesive must be designed for the summer winter environment can use neutral formula, can in 10-35 degrees ambient temperature the sustainable and stable operation.
3, Adhesive in the coating to the substrate should not only have good suspended also needs certain permeability, suspension is inserted in order to make the cloth of adhesive can make glue full wrap cloth, after curing have better security back to revolutions, glue need to infiltrate the net cover substrate 2-3 layers, in order to achieve the net cover full contact adhesive, if too much penetration can cause upper matrix adhesives is less, parcel is, reduce the amount of glue the emery cloth cannot fully to reduce safety back to revolutions.
4, The daily production environment will have temperature difference, so the adhesive in the formula design needs to adapt to the temperature difference of five degrees does not affect the production, otherwise it will appear the phenomenon of wire drawing or glue, leading to unstable flaps quality, the machine can not be normal production.

5, The softening temperature of the glue in the production process should be control between 45-50 degrees, if the temperature is higher than 50 degrees, it is easy to shorten the preservation period of the adhesive, if the adhesive is cured in the rubber pump, rubber tube and glue mouth, the need to replace the rubber tube, resulte in unnecessary losses, affecting the production.
6, According to the four seasons temperature difference, domestic adhesive storage life should be at room temperature can maintain more than three months, and it can make adhesive walk on a hot summer domestic general logistics, can withstand the temperatures of 50 degrees exposure for 3 to 5 days, and to be able to meet these requirements of adhesive enterprises must have a complete set of advanced production technology can only prolongs the storage life of as far as possible that adhesive products.
7. The inner diameter of the packaging drum of adhesive should be matched with the automatic rubber pump. The inner diameter of the drum needs to be accurate. Packaging barrels in the transport process absolutely prohibit extrusion, if the outside of the barrel after extrusion, pressure plate can not be pressed, resulting in colloidal loss, economic loss.With the transformation and upgrading of abrasives and abrasives enterprises, the popularity of automatic production equipment of flap wheels, single-component adhesive is also increasingly used by manufacturers with the popularity of automata, replacing the traditional manual use of two-component adhesive. Faced with different adhesives, the process used will be greatly different, the single-component adhesives need us to constantly improve the core technology of research and development, optimize the production process, reduce the production cost, in order to produce the product with the automaton production process highly consistent
