Those glue are environmental glue, Jiangsu Meijing tells you

2021-05-26

Glue is not environmentally friendly, why zero formaldehyde What are the main adhesives for decoration and furniture production 1. Urea formaldehyde resin adhesive -- urea and formaldehyde 2. Melamine glue -- melamine + formaldehyde 3. Phenolic adhesive -- Phenol + formaldehyde 4. Opal gum 5. Instant rubber 6. Hot melt adhesive Note: not all adhesives contain formaldehyde. Urea formaldehyde resin adhesive, melamine adhesive and phenolic adhesive must contain free formaldehyde, while emulsion adhesive, universal adhesive and hot melt adhesive do not necessarily contain formaldehyde (unless formaldehyde is added as preservative). Characteristics and uses of furniture adhesives Urea formaldehyde resin adhesive Urea and formaldehyde are formed by condensation reaction. Features: 1. Good stickiness; ② Low cost; ③ High adhesion strength, temperature resistance and water resistance. Usage: widely used as adhesive of decoration materials Melamine glue Melamine and formaldehyde are polymerized under certain conditions. Features: 1. Good water resistance; ② Low toxicity; ③ It's expensive. Its uses are as follows: 1. Used as impregnated paper; 2; ② It is used to modify urea formaldehyde adhesive. Phenolic resin Phenolic adhesive is made of phenol and formaldehyde, which is polluted by formaldehyde and phenol, Features: high price, good aging resistance, high bonding strength, generally used for outdoor use. white glue The characteristics are as follows: 1; ② It can be formed by cold pressing and takes a long time to form adhesion; ③ Poor water resistance; ④ The adhesion is general; ⑤ The price is more expensive. Get it right away Instant is also known as all-purpose adhesive. The characteristics are as follows: 1. Gluing is carried out under cold pressure with high speed; ② The price is expensive; ③ Good adhesion. Hot melt adhesive Hot melt adhesive is a kind of solvent-free thermoplastic polymer. It is a solid at room temperature, melts into a fluid when heated, and hardens rapidly when cooled to produce adhesive force. There are mainly several types of vinyl acetate, polyamide and polyester. Its characteristics are as follows: 1; ② Hot melt and cold solidification; ③ It's expensive. I remember that E1 is regarded as environmental protection furniture. We must ask the manufacturer to show the test report (physical performance report and chemical content report). The type and content of glue largely determine whether the furniture is environmental protection and environmental protection level. Environmental protection furniture must use environmental protection glue. The so-called zero formaldehyde furniture is just a beautiful legend, Because wood itself contains trace formaldehyde.

Jiangsu Meijing new material reminds you the reason and solution of carton opening

2021-05-21

In the process of sticking cartons, we will encounter the problem of opening the paper box, and at the same time, there are many solutions Degumming is due to the lack of bonding fastness and cracking, the main reasons are summarized as follows: (1) Insufficient glue amount (2) The development time of glue is too long or too short (3) The adhesive is difficult to penetrate the surface, and it can penetrate into the paper, and the effect of infiltration is poor. (4) The high and low temperature properties of the adhesive are unbalanced, low temperature is easy to brittle, and it is not resistant to high temperature. For the above problems caused by glue, the adhesive suitable for the paper box material should be selected, and the choice and use of adhesive are also very important. First, to solve the problem of insufficient glue amount, we should increase the amount of glue properly. Secondly, the adhesive with moderate opening time should be selected, and the paper box can not have good bonding effect if it is too long or too short. In addition, the selection of the glue type and brand should be appropriate. Finally, pay attention to season change, not take too much at once when taking goods. The ambient temperature of the paste box workshop will also have a certain influence on the adhesive. If the workshop temperature is too low, the adhesive will set immediately, which will affect the bonding fastness. Even if the amount of glue is more, it will not work. Of course, the less glue is, the more sensitive to the room temperature, so in winter, the temperature of the workshop should be kept above 20 degrees, and then leave the factory after drying at normal temperature. Remember to deliver the goods without drying in winter.

Biodegradable adhesive and its preparation method, application and process

2021-05-19

In recent years, the development of adhesive industry is very rapid and the application scope is widening day by day, which plays an extremely important role in various industries. However, traditional adhesives are difficult to degrade in the natural environment. After being applied to plastics, leather, paper and other products, these products enter the environment after they are abandoned. Because of the non degradation, it has become a major hidden danger of natural environment protection. Therefore, solving this problem has gradually become a hot topic in research and development. In recent years, a few researchers have begun to study degradable adhesives, for example, cn201310237769.0 reported the preparation of adhesive for double-sided tape by polymerization of succinic acid, adipic acid, 1,3-propanediol, 1,4-butanediol, catalyst and crosslinker. Although the patent is described as biodegradable, it is not clear how much the molecular weight and biodegradation rate of the synthetic polyester adhesive are. Moreover, the prepared adhesive is mainly diluted by organic solvent. In addition, according to the analysis of synthesis process, the cost is very high. Generally speaking, the development of adhesives with simple production, easy operation, low cost, biodegradability and water-based diluent is still rare.
