“e-starch”:

“e-starch” is an easy starch for automatic corrugate machine, as starches have many other industrial applications such as textile, pharmacy, food etc.

 This “e-starch” is designed only for the automatic corrugate machine.

“e-starch” is available in ratios 1 kg e-starch: 4 litre water and

1kg e-starch: 5 litre water.

The glue made from “e-starch” will be thermosetting adhesive,

This glue usually has some quantity of free starch and ungelatinized         

Starch, the free starch gets gelatinized by the heat of corrugating medium

and gives a stronger bonding.

 

Glue Preparation Method (200 kg) 1:4.

 

•  Take (approx 120 litres) of water in a stirring vessel.

•  Open a “e-starch” bag and you find a packet of glue compound (chemical) inside the bag, cut the packet and mix the glue compound (chemical) in a separate bucket having approx. 2 to 3 litres of water.

•  Now add “e-starch” powder in the stirring vessel and stir for 1 minutes till the starch gets dissolve.

•  Now put the chemical compound solution in the vessel and stir for approx 30 minute.

•  After 30minutes glue gets thick, you may add another 30 to 50 litres of water and adjust viscosity as per the requirement.

• (Note: stirring 30minute will cook the glue and help to produce a good   quality glue)

•  Check and set the viscosity “between” 18 to 24sec in ford B4 cup. For single backer and “between” 25 to 35 for double backer.
  

 

(Note: To set the viscosity for single backer and double backer you may need approx + 10ltrs of water)

(Note: 1. it is must to have a high speed mechanical stirrer with minimum 3hp motor and 1440rpm for preparation of glue)  

Advantages:

• Easy to mix
• Polymers within starch upon gelatinization absorb water and during cooling gets entangled with paper fibres and thereby bridges the two sheets of paper.
• Lower consumption of glue
• Maintains viscosity even at 65 degree Celsius
• Maintain solid content
• Good bonding due to low gelatinization
• “e-starch” can be used for both operation with slight change in viscosity.
