In recent years, there have been many problems in China's manufacturing industry, which restricts the pace of rapid advancement. As a part of the manufacturing industry, the laser cutting industry is also faced with many problems, so the laser cutting machine industry needs to continuously adjust to the current development situation of China's manufacturing industry. Hot Melt Adhesive For Express Bag Express bag sealing with hot melt adhesive, generally used for the sealing of various express bags, some people will feel that the bonding strength is not enough when using, resulting in the opening of the express bag in the middle of the situation. The hot melt adhesive material used to seal the express bag has been fixed. If you want to improve its bonding strength, it can be achieved by the following methods: Hot Melt Adhesive For Express Bag,Express Bag Sealing Glue,Express Bag Adhesive Sealing,Express Bag Sealing Hot Melt Glue Shenzhen Tongde New Materials Technology Co., Ltd. , https://www.tdhotmeltglue.com
China's rapid economic development, through the introduction and imitation, laser cutting machine entry barriers quickly reduced, the localization progress accelerated, private laser cutting machine companies have emerged, the international brands take root. With the acceleration of transformation and upgrading, various problems will inevitably appear in all enterprises and become an obstacle to the industries in transition.
The price of the vicious competitive laser cutting machine is mainly determined by the production cost, technical cost, brand effect and market environment. Some laser Equipment companies do not hesitate to fight price wars to increase product sales for the benefit of their own companies, leading to market confusion. The vicious competition has not only caused the production of laser cutting machines to appear sluggish, which has damaged the interests of many businesses, but also caused the development of their industries to a certain extent.
Lack of Core Competence The healthy competition in the laser cutting machine industry is bright, legitimate, legal, cooperative, win-win, and inclusive. The benign competition in the laser cutting industry must first improve the company's core competitiveness, and secondly it must have good marketing methods. The market for laser cutting machines needs to be maintained together. Only by establishing a correct conception of competition can we establish a sound market competition environment, promote the development of the laser industry even better, and even promote the progress and development of the society.
With the increasing maturity of laser cutting machines, the competition among brands, products and enterprises is not a single factor competition. In addition to the dominant factors such as price and quality, services, added value, channels, and corporate development strategies, etc. Implicit elements are also an important aspect of the long-term development and sustainable development of enterprises and brands.
1, improve the surface roughness of the sticky object
When the hot melt adhesive is well infiltrated on the surface of the bonded material, the roughness of the surface is conducive to improving the infiltration degree of the hot melt adhesive on the surface, increasing the contact point density between the hot melt adhesive and the bonded material, and thus improving the bonding strength.
2. Penetration
The bonded joint, by the role of the environmental atmosphere, is often penetrated into some other low molecules, for example: the joint in a humid environment, the polymer adhesive layer in the machine solvent, the solvent molecules penetrate into the polymer, the penetration of low molecules first deforms the adhesive layer, and then enters the interface between the adhesive layer and the adhesive, so that the strength of the adhesive layer is reduced, resulting in bonding damage.
3. Migration
Due to the poor compatibility of these small molecules with polymer macromolecules, they are easy to migrate from the polymer surface or interface, and the small molecules that migrate out will hinder the hot melt adhesive and the adhesive material if they gather at the interface.
4. Apply pressure to the bonding surface
When bonding, pressure is applied to the bonding surface, so that the hot melt adhesive is more easily filled with pits on the surface of the bonded body, and even flows into deep holes and capillaries, reducing the gas overflow on the surface of the bonded body and reducing the porosity in the bonding area.
5. Thickness of rubber layer
The thicker adhesive layer is easy to produce bubbles, defects and early fracture, so the adhesive layer should be as thin as possible to obtain higher bonding strength, in addition, the thermal stress caused by the thermal expansion of the thick adhesive layer after heating in the interface area is also relatively large, which is more likely to cause joint damage.
