Adhesives, with their unique properties, play a key role in various industrial and daily life applications. There are many types of them, and they can be mainly divided into three types: organic, inorganic and composite.
The first one to bear the brunt is organic adhesives. The main components of these adhesives are organic matter, including starch, lignin, protein, etc. These components achieve strong bonding to various materials through intermolecular forces such as hydrogen bonds and van der Waals forces.
Starch is a common organic adhesive that comes from a wide range of sources, such as rice, corn, potatoes and other foods that are rich in starch. In wood processing, starch is used as an adhesive to help bind wood pieces tightly together to form strong boards.
Lignin is a type of complex organic matter present in plant cell walls. Its content in nature is second only to cellulose. Because of its good adhesion and weather resistance, it is often used in the paper making process to give the paper a certain strength and toughness.
As for protein, it is also a commonly used organic binder. The peptide chains in proteins can be tightly combined with other substances through intermolecular forces such as hydrogen bonds and van der Waals forces. This property makes proteins widely used in the food packaging industry. Gelatin is a common protein binder used to maintain the freshness and taste of food.
In summary, organic adhesives are widely used in many industries due to their wide variety and good environmental protection. Whether it is wood processing, paper making or food packaging, they all play an important role.
Inorganic binders include cement, lime, and phosphates. When these substances are mixed or solidified, they form strong binding forces through ionic or covalent bonds. The formation of this chemical bond gives the inorganic adhesive extremely high structural stability and can resist high temperature, acid and alkali erosion.
Because inorganic binders are resistant to high temperatures, acids and alkalis, they are widely used in fields such as building materials and ceramic crafts. For example, in the field of construction, inorganic adhesives are widely used in the preparation of concrete, mortar and other materials, providing a solid structure and stable support for buildings. In ceramic technology, inorganic binders are used to make various ceramic products, such as ceramic tiles, porcelain, etc., to make these products have higher hardness and wear resistance.
Finally, let’s take a closer look at this amazing substance called composites. This is a unique adhesive that cleverly combines the advantages of organic and inorganic adhesives, with both the excellent viscosity of organic adhesives and the stable chemical properties of inorganic adhesives.
Under scientific formula design, this composite material can exert unimaginable bonding capabilities. The scientific principles contained in its formula enable it to maintain excellent bonding effects under various complex environmental conditions. No matter it is high temperature, low temperature, humidity change or acid-base environment, it will not have any impact on its adhesiveness.
Through precise process control, this composite material can maximize its own advantages and greatly improve its overall bonding performance. This enables it to provide more stable and reliable solutions when dealing with more complex and demanding application requirements.
Therefore, whether in construction, machinery manufacturing, or in high-end fields such as aerospace and automobile manufacturing, composite materials play an irreplaceable and important role. Its emergence has undoubtedly opened up new possibilities for our industrial development and satisfied more and more complex application requirements.
When making biofuel pellets, selecting an appropriate binder is a crucial step, which requires a combination of raw material characteristics, molding process, environmental benefits, cost and other factors. For example, when making bio-pellets, we usually prefer to use lignin as a natural binder because of its better compatibility with wood fibers; however, in the process of producing bio-coal, we may choose to cost Lower lime serves as an inorganic binder, which not only provides excellent bonding ability, but also fixes sulfur during the combustion process, thereby reducing environmental pollution.
The amount of binder used during the manufacturing process has a direct impact on the performance of biomass fuels. Adding too much adhesive can lead to unnecessary cost increases. This is mainly because the excess binder does not provide higher thermal energy for the fuel, but increases raw material consumption, thus causing waste.
On the other hand, too much binder may negatively affect fuel combustion efficiency. This is because excess binder may affect the combustion process of the fuel, reducing the fuel's combustion efficiency and calorific value. Therefore, controlling the reasonable amount of binder added can not only ensure the calorific value of biomass fuel, but also ensure its combustion efficiency and maximize energy utilization.
In order to find the most suitable amount of adhesive to use, it is usually necessary to experiment and test different ratios. This process may require trial and error to determine the optimal mix.
