What materials don t stick to hot melt adhesives, and why doesn t hot melt adhesives stick?

There are many materials that are not sticky with hot melt adhesive, and now the electronics, fabric shoes, packaging, woodworking, etc., which are bonded with hot melt adhesive, have their own different characteristics, and the effect will not be ideal if the hot melt adhesive of the electronic class is used to stick the packaging class, and the effect will not be ideal if the hot melt adhesive is used to bond the harder things and the products with a relatively large area. If it does not meet the requirements, it will not be bonded Therefore, in fact, there are too many materials that are not sticky to hot melt adhesive, and there is no way to list them one by one

For now, hot melt adhesives.

There is a one-to-one correspondence relationship, and each glue is not omnipotent, but has a certain pertinence. What material to say is non-stick hot melt adhesive, at low temperature, it is not sticky, and in the case of temperature, it is sticky. The effect of stickiness depends on the situation after cooling, at present, a thing is physical phase viscosity, but more and more began to develop to chemical phase viscosity.

Teflon (Teflon).

Sharp coating new material non-stick coating can achieve the effect of hot melt adhesive, label, tape, self-adhesive and transparent glue without sticking at all, but it cannot withstand too high temperature.

Silicone-containing materials, depending on what hot melt adhesive.

Oily and non-sticky hot melt adhesives.

There are many reasons why hot melt adhesive does not stick, depending on what factors affect its performance, and temperature is one of the most common reasons at present. As the weather gets colder, the glue often appears to have cured when the material is bonded. Even if it is not cured, the optimal bonding effect is missed.

Even in some northern regions, the temperature of the material is quite low, resulting in unsatisfactory bonding.

Hot melt adhesive is a kind of plastic adhesive, its physical state changes with temperature within a certain temperature range, and the chemical properties remain unchanged, it is non-toxic and tasteless, and is an environmentally friendly chemical product. Because the product itself is solid, it is easy to package, transport, store, solvent-free, non-polluting and non-toxic; As well as the advantages of simple production process, high added value, high adhesive strength and fast speed, it is favored.

In the process of use, you will encounter "glue non-sticking", "wire drawing problem", "temperature too high bubbles", "cold stickiness" and so on. And in these cases, there is often no problem with the product itself. Taking "glue non-stick" as an example, there are many reasons why hot melt adhesive is not sticky, depending on what factors affect its performance, and temperature is one of the most common reasons at present.

As the weather gets colder, the glue often appears to have cured when the material is bonded. Even if it is not cured, the optimal bonding effect is missed. Even in some northern regions, the temperature of the material is quite low, resulting in unsatisfactory bonding.

The following points should be paid attention to when banding edges:

1) Pay attention to the range of substrates applicable to different types of products.

2) It is best to try to seal it with a discarded small board before each start, so that the problem can be found as soon as possible.

3) When the ambient temperature is too low, the edge banding, the plate can not be too cold, too cold will absorb heat and cool down, affect the bonding of the edge banding strip and the hot melt adhesive, ensure that the plate should be coated with hot melt adhesive, and the glue should be appropriately thicker than in summer in winter.

4) When the ambient temperature is too low, you can make a lampshade on the edge banding machine turntable to heat the edge banding strip, so as not to be too cold and lack of corners or overpower.

5) When the ambient temperature is too low, if the edge banding machine has a preheating device, the preheating temperature should be opened to preheat the plate. At the same time, pay attention to the temperature and speed of use.

6) Due to the large difference in temperature between summer and winter, the opening time of hot melt adhesive is different, pay attention to the temperature change.

7) Inventory products should be based on the principle of first-in, first-out use.

Hello; Do you mean non-stick when heated?

Is it still non-sticky at room temperature?

The normal best viscous temperature is 120-150 degrees, you see, how much is your glue warmed with?

The hot melt adhesive that is stained with water cannot be sticked, because the hot melt adhesive cannot be soaked, it will not stick strongly. Hot melt adhesive is a decoration tool, which is commonly used in material gluing, such as sealing and filling refrigerators, automobile lighting industry, non-woven fabric industry, etc. Scope of application of hot melt adhesive:

1. Hot melt adhesive is widely used and can be seen everywhere in daily life. It covers food, clothing, housing and transportation. 2. Hot melt adhesive is also used as a composite adhesive in shoes.

The hot melt adhesive that is stained with water cannot be sticked, and because the hot melt adhesive cannot be soaked, it is not sticky. Hot melt adhesive is a kind of decoration tool, which is widely used in material gluing, such as sealing and filling refrigerators, automobile lamp industry, non-woven fabric industry, etc.

Scope of application of hot melt adhesive:

1. The application of hot melt adhesive is very common and can be seen everywhere in daily life, but most people don't know it. For example, clothes contain hot melt adhesive, self-love necklines, cuffs, placket and leather clothing all need to be bonded with hot melt adhesive.

2. The shadow of hot melt adhesive can also be seen in shoes, whether it is sports shoes, sandals, leather shoes, canvas shoes or high heels, these are all hot melt adhesives used as composite adhesives, so that the shoes will be more durable and durable.

3. Hot melt adhesives can often be seen in home decoration materials, such as curtain cloth, seamless wall coverings, wooden furniture, table cloths, room doors, etc., so it is also necessary to stop bonding with hot melt adhesive.

4. For example, sol is also widely used in the automotive industry, such as automotive interiors, automobile headliner cloth, soundproof cotton, seat covers, damping soundproof panels, carpet assemblies, etc., which are bonded and composite with hot melt adhesive. In fact, the scope of application of hot melt adhesive is far more than these, with the advancement of consumer technology from time to time, its role and scope of application are also expanding from time to time.

Hot melt adhesive holes are often used in our daily life, and the clothes and shoes we wear contain hot melt adhesive, and they are often used when doing handicrafts. So what can't be done with hot melt adhesives? What is the scope of application of hot melt adhesives?

What can not be adhered to the hot melt adhesive that is to be stained with water, because the hot melt adhesive cannot penetrate, so it is not firmly adhered to. Hot melt adhesive is a kind of decoration tool, which is widely used in material gluing, such as sealing and filling of refrigerators, automobile lamp industry, non-woven fabric industry, etc.

What is the scope of application of hot melt adhesives.

1. The application of hot melt adhesive is very wide, and it can be seen everywhere in daily life, but most people don't know it. Hot melt adhesive almost covers our food, clothing, housing and transportation, for example, the clothes we wear contain hot melt adhesive, self-love neckline, cuffs, placket and leather clothing need to be bonded with hot melt adhesive.

2. We can also see the shadow of hot melt adhesive in the shoes we usually wear, whether it is sports shoes, sandals, leather shoes, canvas shoes or high heels, these are all hot melt adhesives as composite adhesives, so that the shoes will be more firm and durable.

3. Hot melt adhesives can often be seen in our common home decoration materials, such as curtain fabrics, seamless wall coverings, wooden furniture, table cloths, room doors, etc., which also need to be bonded with hot melt adhesives.

4. For example, sol is also widely used in the automotive industry, such as automotive interiors, automobile headliner fabrics, soundproof cotton, seat covers, damping soundproof panels, carpet assemblies, etc., which are bonded and composite with hot-melt adhesive. In fact, the scope of use of hot melt adhesive is far more than these, with the continuous improvement of production technology, its role and scope of application are also expanding.
