Adhesive * has no mold, no moth, not afraid of rat bite performance, to ensure that custom lift-up flaps book is protected from microbial and animal erosion when stored. The mixture not only has various requirements for the finished product, but also its solution properties can not be ignored. Adhesive working solutions also have certain requirements for viscosity, viscosity and concentration, which must be adapted to the material and drilling conditions. For example, the stickiness of the paper with high adhesion smoothness is larger than that of the paper with low dry smoothness, and the glue of the lacquer cloth is thicker than that of the cloth with the cover.

custom lift-up flaps book adhesive requires a certain viscosity, so that the cover material can be attached to the book block for at least 5 to 8 minutes without the force of the cover material returning to the original shape of the two dead compound off contact, this time is the necessary time to complete the binding work. The viscosity of the dry mixture mainly depends on its cohesion strength. The cohesion strength of the adhesive is large to ensure that the custom lift up flaps book is not extended, but the adhesive with too much cohesion strength is not easy to spread on the surface of the twist.

For the adhesive, it is necessary to ensure that the adhesive has good fluidity, so that it can be filled in all the concave places on the surface of the bonded object, that is, the surface of the bonded object is covered. The nature of the reaction adhesive fluidity is viscosity, in many industrial areas of adhesive application, it should be noted that the solvent-based adhesive will change with the solvent volatilization, if the water or organic solvent in the adhesive may evaporate, then the adhesive will be more and more thick, if not take appropriate measures, At the beginning, the adhesive with appropriate viscosity may have a series of failures such as uneven distribution or insufficient penetration of the adhesive to the bonded material due to excessive viscosity.

custom lift-up flaps book adhesives should be free of unpleasant smells and do not release harmful gases when bonding. Acid alkalinity is also moderate, or weak alkalinity, if there is free acid or too strong alkalinity in the glue, it will also affect the bonding fastness, or damage the material to be bonded. The composition of the adhesive should not contain substances that can make the ink fade, otherwise it will also affect the beauty of the custom lift-up flaps book.

Tea Plucking machine are often used in garden operations to remove weeds and loose shrubs. Why do many people like to use Tea Plucking machines? This is because its work efficiency is very high, the operation speed is very fast, the key is the quality of the operation is also good, the overall performance is a very good garden tool. The main function of Tea Plucking Machine is to mow the lawn and maintain the lawn, then how to operate the Tea Plucking Machine? What do you need to pay attention to when operating? Let's take a look.

After the battery switch of the knack-type cutting Machine is turned on, the strap is carried behind the back, and the lithium battery power is transmitted to the working part of the Tea Plucking Machine through the flexible shaft. The operator holds the joystick in his hand and can cut while walking. Because the lithium battery is carried behind the back, the operation is sensitive, not affected by the terrain and slope, and can be freely operated up and down, left and right, especially in line with the complex terrain of grass cutting operations. When cutting grass below 13 cm, a one-way blade can be used to cut it directly; When cutting weeds above 13 cm, two ups and down cuts can be used, that is, the head part is cut first, and it is strictly prohibited to impact cutting when using the Tea Plucking Machine, otherwise it will hurt or destroy the machine due to the inertia effect.

After the Tea Plucking Machine installed with a cutter head is started or is working, others other than the operator must be 3 meters away from the machine. In addition, when transferring the operation point, the lithium battery switch must be turned off, so that the blade stops rotating, and the switch is turned on again at the new operation point, and the grass cutting operation is carried out after further operation.

Although the Tea Plucking Machine is a small mechanical device, the working part of the tea plucking machine is a blade, so it has certain safety hazards if it is improperly operated. Therefore, we must be careful when using it, only in this way can we prevent problems before they happen.
