☑️ Types of adhesives
☑️ ordinary glues (epoxy glues)
These types of adhesives are composed of a combination of two chemicals and after mixing, they become integrated. The fixing time of these adhesives is usually short, and they are used to glue various materials, such as metals, wood, plastics, etc.
☑️ adhesive tape
It is a type of industrial adhesive that comes in the form of long and narrow strips. These types of adhesives are usually double-sided, in the sense that they have the ability to stick to two different surfaces. Duct tape is usually sold in rolls or large containers and can be cut to desired length. Adhesive tape is very popular as a simple and effective solution for gluing different materials together. Due to the ability to quickly and easily cut strips, they can perform well in many applications. These adhesives can be used in various industries, handicrafts, packaging, decoration, home repairs and even in medical applications. It is also used as a convenient alternative to conventional adhesives (such as liquid glue) because it requires less preparation and also allows parts to be glued together and removed quickly when necessary. In addition, adhesive tapes can be used to make temporary connections or to position parts before permanent gluing. be in thickness, length and width and each one is suitable for their own specific applications. Also, some of these tapes have special features such as resistance to water, heat, direct light, etc., which you can choose depending on your needs and application.
☑️ Thermal adhesives
These types of adhesives are melted by heat and create a strong connection after cooling. They are used for vinyl and fabric applications, such as gluing fabrics, eyeglass frames and handicrafts.
Silicone adhesives: These types of adhesives are usually made of silicone polymers and are used for waterproofing applications and in some medical cases (eg water adhesion in case of skin lesions).
PVA glues (vinyl acetate glue): These types of glues are made on the basis of polyvinyl alcohol and are used for gluing papers, cartons and wooden materials.
Adhesives: these types of adhesives are based on latex (a polymer mixture of fine particles) and are used for gluing soft and flexible materials, such as foam, fabrics, carpets, etc.
Superglue adhesives: These types of adhesives have very strong and fast adhesion and are suitable for gluing flat and small surfaces, such as metals, glass and ceramics.
Wood glues: These types of glues are especially used for gluing wooden parts together and creating a strong connection in wooden buildings and repairs.
Ceramic adhesives: These types of adhesives are used for gluing and repairing pottery, ceramics and related technologies.
What are water soluble adhesives?
Water soluble adhesives are available as a special type of adhesives that can dissolve in water. These types of adhesives are usually made of water-soluble materials, meaning that after applying and bonding the two materials, if they come into contact with water, they will dissolve and their adhesion will weaken or disappear. This feature is used especially for special applications and when adhesive parts need to be easily separated.
Usually, these types of adhesives are used for temporary labeling, manual work, and needs that require parts to be stuck together for a certain period of time and finally separated with water. Also, water-soluble adhesives may be used in some artistic and decorative works.
An important thing to note is that water-soluble adhesives generally have much less strength and adhesion than other types of adhesives. Therefore, before using this type of glue, you should check the amount of adhesion required and pay attention to whether this type of glue is compatible with your needs or not. Also, depending on the type of materials to be bonded, their adhesion to water may vary. Therefore, it is important to choose the most appropriate type of glue according to the work.
☑️ Principles and general method of using all kinds of adhesives and gluing objects:
Gluing different components and parts together has well-defined steps that must be followed to create a strong and secure connection. Below are the general principles and methods of gluing:
Preparation of surfaces: The surfaces of the parts must be clean and dry to create better adhesion. Ensure that there is no grease, dust, oil, drains and contaminated materials. If necessary, clean the surfaces with special paper or suitable detergent.
Choosing the right adhesive: Adhesives are selected based on the type of surfaces and materials to be bonded together. Some adhesives work better for certain surfaces and this is related to the environment and application requirement.
Chipping (optional): In some cases, it is possible to create small and insignificant chips on the surfaces to better accept the adhesives and create a stronger bond. This is especially useful for gluing flat and large surfaces.
Adhesive allocation: apply the adhesive carefully and in sufficient quantity on the desired surfaces. Avoid applying too much or too little glue to get the best result.
Gluing: Carefully glue the parts together and apply proper pressure on them to create a good glue between them. If possible, use tools like (such as fasteners, elastic bands, etc.) to make a stronger connection.
Fixation time: Adhesives usually need a certain time to fix and create strong adhesion. This time may vary up to a few minutes or even a few hours. Make sure you observe the length of time the glue sets.
Drying and separation: After gluing, it is better to spend enough time to dry and fully stabilize the adhesives in order to create a stronger and more reliable connection. Do not damage the materials. In any case, before gluing, it is better to carefully read the instructions of the manufacturers of all types of glue and follow their tips and recommendations. Also, in some applications, you may need special environments such as heat or humidity to consider these needs.
