Adhesives and Chemicals- Key Ingredients in Paper Industry
Paper is used everywhere. Schools, colleges, companies,
businesses, all use papers in enormous amount. And the paper industry is theone, which is one of the largest users of chemicals and adhesives. The generic
word "paper", includes a wide range of products of many different
kinds. Out of which, many of them are made by the use of adhesives and
chemicals. Every product increases the use of adhesive.
As we all know, the adhesive is a substance applied on one
or both surfaces to be held together to resist their separation. It makes the
bond between two substrates stronger. Many different kinds of adhesives are
available in the market today,and each
one has its different use.
On the other hand, the chemical is an element having the
specific molecular composition and can be produced as well as used in a natural
chemical process.
Adhesives and
Chemicals- Key Ingredients in Paper Industry
For the manufacture of paper, various kinds of chemicals are
used. Some of them are mentioned below:
·
Optical
brightening agent: The use of this chemical on paper makes the paper look
more clean, white and glossy.
·
Pigment:
To increase the whitening in the paper, the combination of optical brightening
agent and pigment is widely used. The widely used pigments in the paper
industry are violet and blue dyes.
·
Retention
agent: The binding of fillers to the paper is done by the use of the
retention agent. This chemical is a polymer which has a high cationic group. Polyethene imine and polyacrylamide are the
chemicals used in this process.
·
Caustic
soda: The increased pH in the pulping process of fibres are the result of
the addition of caustic soda during paper manufacturing. This results in the
smoothening and swelling of the fibre ultimately helping in its grinding
process.
·
Sizing
agent: AKD (alkyl ketene dimer) and ASA (alkenyl succinic anhydride) are
popularly used nowadays to make paper
water resistant to make them usable for printability or specific writing.
·
Wet strength
additive: This additive is important to be used during the process of paper
manufacturing to make sure that the paper does not loses its strength even after becoming wet. This chemical is widely
used at the time of production of tissue papers. Chemicals included in this
additive are polymines, melamine and
epichlorohydrin.
So these are the adhesives and chemicals used in the process
of paper manufacturing. These are a vital part of the production of any kind of
paper. The Pidilite textile and paper chemicals series have
good options for just about anyone. The Pidilite
industrial adhesives offer amazing products to get things done.
