Analysis of the Reasons for Uneven Adhesive Volume and Its A

writer:点胶设备 time:2019-04-16 11:59 clicks:
Among many dispensing problems, the non-uniformity of glue content is an important factor affecting the bonding or sealing. The quality of product glue bonding will be greatly reduced if the non-uniformity of glue concentration or proportion controlled by the two-component dispensing valve is as large as that of the ceramic dispensing valve. Therefore, the factors causing the non-uniformity of glue content need to be analyzed from many aspects. The following are the factors causing the non-uniformity of glue content. Some suggestions and treatment methods given by the manufacturer.

Whether it is used in the production of small motor glue or stainless steel on both sides, the influence of uneven glue amount should be avoided. This is the reason that the quality of control glue of ceramic dispensing valve and other accessories is not good. The reason of uneven glue may be related to the nature of adjustment. Generally speaking, glue needs to be stirred uniformly before applying glue to avoid being used for a long time and gradually stratified, resulting in glue. When the degree and sealing strength decrease, the integrity of motor glue coating or the strength of stainless steel bonding will be affected. Ceramic dispensing valve manufacturers suggest that before use, stirring should be uniform to avoid the uneven glue content to be suitable for bonding use. Gradually stirring the uneven glue to uniform will enhance the application effect. When the glue flows to the ceramic dispensing valve, it will flow more stably and evenly to the bonding sealing surface. 。

Effect of related accessories on colloid
 
The needle at the bottom of the ceramic dispensing valve is also one of the factors affecting the glue content. It takes a long time to finish the motor gluing and to control the glue content of stainless steel. The dispensing needle may adhere to a part of the solidified glue. If this part of the solidified glue is not solved in time, it will adhere to this part, causing blockage, resulting in uneven glue output and affecting the glue production status, it can be straightened. Replacement or soaking with acetone solution to remove the curing adhesive is suitable for the production of batch motor coating line and stainless steel bonding on both sides. This is the potential factor that causes the uneven adhesive volume summarized by ceramic dispensing valve manufacturers for a long time.

To ensure the normal use of dispensing machine, besides guaranteeing the setting of parameters and paths, to prevent the quality of glue from causing uneven glue content and affecting the value of finished products.
