Production process requirements for one-component adhesives in flap disc

flap disc automata has been widely promoted in the market and used in some enterprises. The one-component adhesives that accompany the automata are gradually being concerned by manufacturers.

Since the enterprises that used imported equipment in China have maintained doubts about the research and development capabilities of domestic adhesive suppliers and the production process technology, they are worried that the use of adhesives that do not match the automatic machine process will cause more damage to the machine and cause equipment damage. Therefore, imported adhesives with high cost have been used. In recent years, with the popularization of domestic automata, the self-developed single-component adhesives have been paid more and more attention by enterprises. The company is more concerned about the quality and cost of the adhesives matched with the process while understanding the automata. .

As the saying goes: "It is difficult for a clever woman to be without rice." Even if the advanced and stable automation equipment does not have an adhesive that matches the process, it will not be able to automate the production of the automaton.

According to the use process of single component adhesive on the flap disc automatic machine, it can be classified into the following requirements:

1. One-component adhesive is applied on the automatic machine. In order to control the precise amount of glue, there is a relatively high requirement for the viscosity of the adhesive. It is necessary to make the viscosity uniform and stable. The selection of raw materials must be high quality. And a higher production process is required to ensure uniformity of viscosity.

2, the production environment of the flap disc automatic machine is at a constant temperature of about 20 degrees, but at present, there are not many customers who can meet the requirements in China. In order to make the quality of the product consistent, the equipment is more stable, the adhesive must be designed as summer in the formula. Neutral formula that can be used in winter environments, capable of stable and stable operation at 10-35 degrees ambient temperature.

3. Adhesive should have better suspension and certain permeability when it is glued to the substrate. Suspension is to make the emery cloth insert into the adhesive to make the adhesive fully wrap the emery cloth, and it will be safer after curing. The number of rotations needs to penetrate into the 2-3 layers of the base of the net cover to achieve sufficient cross-linking and bonding of the net cover. If the penetration is too much, the adhesive on the upper part of the base will be less, and the amount of glue wrapped around the abrasive cloth will not be fully wrapped. Thereby reducing the number of safe revolutions.

4, the production environment in the daily temperature will have a temperature difference, so the adhesive needs to adapt to the five-degree temperature difference in the formulation design does not affect the production, otherwise there will be the phenomenon of drawing or silicone, resulting in unstable blade quality, the machine can not be produced normally.

5, the softening temperature of the glue in the production process should be controlled between 45-50 degrees, if the temperature is higher than 50 degrees, it is easy to shorten the preservation cycle of the adhesive, the adhesive is solidified in the rubber pump, hose and glue nozzle, resulting in the need to replace The hose, which causes unnecessary losses, affects production.

6, according to the domestic four-season temperature difference, the shelf life of the adhesive should be able to maintain at room temperature for more than three months, and in the hot summer can make the adhesive go to the domestic general logistics, can withstand 50 degrees of temperature exposure 3-5 Days, and the adhesive companies that can meet these requirements must have a complete set of advanced production technology to maximize the shelf life of the finished adhesive.

7. The inner diameter of the packaging barrel of the adhesive should be matched with the automatic rubber pump. The inner diameter of the barrel needs to be accurate. If it is large, it will easily produce overflow rubber. If the barrel diameter is small, the pressure plate cannot be pressed, resulting in failure to produce. The packaging drum is absolutely forbidden to be squeezed during transportation. If the outside of the barrel is squeezed, the pressure plate cannot be pressed in, resulting in loss of colloid and economic loss.

With the transformation and upgrading of abrasives and abrasives enterprises, the popularity of hundred-page automatic production equipment, single-component adhesives have been increasingly used by manufacturers with the popularity of automatic machines, replacing the traditional two-component adhesives. In the face of different adhesives, the process used will be very different. One-component adhesives require us to continuously improve the core technology of R&D, optimize the production process and reduce the production cost, in order to produce products that match the height of the automatic machine production process. In order to enable users in the industry to understand and master it more scientifically and in a standardized way, it is possible to create more and more benefits for the automatic machine to take off the wings.
