●
Why we need Adhesive
○
To stick various plies of Kraft Paper
○
To get good strength to Board
●
What is starch adhesive
○
When starch is heated in water , it will transform
into a paste like structure.
○
For stronger bonding chemicals are added.
●
Other adhesives other than starch
○
Yes. Like Sodium Silicate. Very few use

●
Solids
○
Expressed in % and shows how
much starch/Modified Starch/chemicals are
present in Adhesives.
○
Refractometer is used if adhesive is solution.
○
Owen method- If adhesive is suspension
○
This parameter signifies how much of water
needs to be dried in the Board making process.
TESTING PARAMETERS
Amylodex Pvt. Ltd 02 Oct 2017 at WICMA level II course Bhaskar BV Reddy
●
Viscosity
○
Resistance to Flow
○
Measured in Sec. Time taken to drain out
○
Many cups are used. Fords Cup,Love Cup,
Brookefield , RVA
○
Very important for stable operations and needs to
be consistent.
○
Normally Manual plants operate at 25-35 sec for
Pasting and Corrugation adhesives ( B4 cup)
○
Auto Plants operate at 40 to 120 sec (B4 )
TESTING PARAMETERS
Amylodex Pvt. Ltd 02 Oct 2017 at WICMA level II course Bhaskar BV Reddy
●
Other testing Parameter
○
Gel temperature.
○
Tack measurement
○
Glue setting time / Green bond
formation
○
Thixotropic behaviour.
○
Gel clarity in case of Pasting
Adhesives
.
