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.

In the stage when the state of hospitality digital signage industry is not very clear, the signage industry has gradually exposed a lot of industry disorder symptoms, such as price war, design does not meet the market standards, principles and other problems, and delivery inspection and other problems. The relationship between the hospitality digital signage industry and consumer supply and demand is no longer the same. Price, creativity, quality and other aspects need to be clearly understood. Next, let's take a look at the problems that may arise in the industry.
hospitality digital signage price war, hospitality digital signage products, especially products, cannot be unified, and almost all of them need to be customized, so the prices of different manufacturers are greatly differentiated. There is no single standard that can be calculated in terms of price, so it is according to the feeling, and the pricing varies from person to person, as long as it is able to win the order, it will inevitably lead to some customers becoming meat buns
The design of hospitality digital signage does not meet the market standards. Due to the customized characteristics of logo products, each product needs to be independently designed or even further designed. If the designer has a low awareness of the hospitality digital signage industry, In the process of design, there is no way to consider the selection and collocation of profiles, after the production process, and then according to the drawings of the product is often unable to achieve the desired effect of customers, that is to say, the goods are not the board, the sales say the hype, the reality is very bony, and the consumer experience is out of the question.
hospitality digital signage raw materials, this question is relatively common, raw materials shoddy, profile standards and specifications are also the hospitality digital signage industry has been criticized. Raw materials are shoddy, and the secret of shrinking profile standards and specifications is also the place where the logo industry has been criticized.
Of course, the chaos is definitely more than that. Let's take a look together. When accepting the finished product, we must carefully check it and find some professional industry personnel to judge from all aspects of hospitality digital signage.

Due to the increased awareness of security protection, the requirements for 4g lte gps tracking devices are no longer just positioning. Therefore, according to market demand, the current 4g lte gps tracking device generally has an automatic alarm function. Many owners only know that there is such a function, but do not know the specific categories and use scenarios. Today, let's sort out a 4g lte gps tracking device alarm series guide.
4g lte gps tracking device alarm is divided into several types: vibration alarm, power failure alarm, low power alarm, speeding alarm, SOS SOS alarm.
1. Vibration alarm: If the locator is set to open the vibration alarm mode before, the car will automatically enter the fortification state five minutes after the shutdown, and once the car has abnormal vibration, it will send an alarm signal to the background. If it is the owner's own operation, then you do not have to ignore the alarm signal, and on the contrary, you must log in to the background to view the real-time condition of the car.
2. Power off alarm: Once the power off alarm is set up, as long as the device detects that the main power supply of the car is disconnected, it will trigger the alarm, and it will also send an alarm signal to the platform. If it is such an alarm, first determine whether the car is running normally, and whether the main power supply is not firm enough when installing the locator. If the car loan company, it is necessary to call the customer to verify the situation, and it is best to have the staff check the electrical condition of the car. If the circuit works then check if the customer himself tried to remove the locator. If this is the case, the location of the locator should be reinstalled and the customer's credit assessment should be reviewed.
3. Low power alarm: This function is triggered when the device power is less than 10%. If the background receives this alarm, it should check the power problem of the device, and charge or replace the battery in time. It is best to replace it as soon as possible, so as not to cause inconvenience to the follow-up work of tracking vehicles.
4.SOS SOS: This is an alarm mode that requires human operation to take effect, for those positioning terminals with SOS keys. If the background receives such an alarm, the owner should be contacted in the fastest time to check the safety of the owner and the vehicle.
5. Speeding alarm: This is also very well understood, as long as the car is traveling faster than the set range, it will send an alarm signal. Generally, this alarm is generated to remind the owner to drive safely. If you are abnormally speeding, you need to check with the owner as soon as possible to determine whether to take other measures.
