Joyachem Adhesives can be defined as a material used for bonding that exhibits flow at the time of application. In geometry, the surface is a two-dimensional geometric figure that limits the space filled with matter, i.e. surface in a theoretical sense. In mechanics, the surface is defined as the edge of a material body, which may be analysed in a molecular scale, micro- and macro size. There are certain adhesion theories based on surface chemical phenomena. In some special cases, either pure adsorption, or electrical or diffusion attractive forces are found at an adhesive-bound interface.
Adhesives have a long list of uses. They are so inextricably linked to our lives that we become oblivious of their presence. But if we look around, we will find some kind of adhesive used in every sphere of our daily lives, be it furniture, gadgets or toys. Their varied use in food packaging to building construction has forced the manufacturers to research and make different kinds to suit different needs. Some are toxic and strong, they serve industrial purpose. Some are mild and free of any kinds of toxics. They are used in making toys for children, infant products or edibles packaging. Some are water resistant and non toxic. For example, adhesives are used in the packaging of ice creams. Liquid can reduce the adherence quality. So you need a strong yet non toxic adhesive which does not come apart when it comes into contact with water or any other kind of liquid.
Traditionally, there were various methods used for fastening, gluing and bonding. They were soldering, welding, brazing and other thermal and mechanical procedures which needed equipment, but now, adhesives are more widely used. They neither need tools and devices nor electricity or batteries to run them. The common uses of adhesives can be divided into two broad categories: Industrial and Commercial Use and Household Use.
Using adhesives instead of traditional binding ensures a reduced cost of production. It neither needs equipments for drilling, welding, soldering or other fastening agents, nor manual force to operate them. Welding is a rigid method which brings physical changes in the materials adhered. If you need to undo the process after using adhesive, there are agents available to serve your purpose. Using them, the fastening or adherence can be undone without distorting the item retaining their original look.
