What are the occupational hazards of adhesives?
Adhesives are substances that bind together materials such as paper, cloth, leather, wood, metal, glass, rubber, or plastic in accordance with established procedures. The adhesive has wide application, easy to use, high economic benefit has many characteristics, from wood processing, construction and packaging industries expanded into clothing, light industry, machinery manufacturing, aerospace, electronic and electrical appliances, advertising, transportation, medical, telecommunications, warehouse and other fields, has become an important and indispensable national chemical products in the life of the people.
There are many categories of adhesives, solvent, oil, adhesives, water-based adhesives, etc., oily adhesives are not environmentally friendly, toxic gas volatilization for a long time, so frequent contacts, the body is still harmful. But the water adhesive belongs to non-toxic adhesive, now enterprise manufacturing, home decoration are in use, therefore, engaged in water-based adhesives relatively secure, Jincheng water-based adhesive rubber industry.
There are many kinds of adhesives. They are classified into polymers, cellulose and proteins according to their chemical composition and properties (NATURAL type). Polymers can be classified into thermosetting adhesives, thermoplastic adhesives, and rubber adhesives. Thermosetting adhesives include epoxy adhesives, phenolic adhesives, urea formaldehyde adhesives, and melamine formaldehyde adhesives. Thermoplastic adhesives include polyvinyl acetate emulsions and other resin adhesives. Cellulose can be divided into cellulose nitrate, cellulose acetate. Proteins (NATURAL) can be divided into animal glue, casein glue, glue, glue blood protein.
