CORRUGATION GUM POWDER

   

 

CORRUGATION GUM POWDER (CGP):



CGP is white glue and is available in various ratios as per the customer requirements. Our CGP works on the concept of stain-hall process system.

Stain-Hall corrugating Adhesive is a thermosetting adhesive. This adhesive usually have some Quantity of free starch and un-gelatinized starch, the free starch gets gelatinized by the heat of corrugating medium and gives a stronger bonding.

Uses: It is used in corrugation flute making machine and on 3ply and 5 ply semi-automatic machines.



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 and solid content
  • Good bonding due to low gelatinization

 

Corrugation Gum Preparation Method (200 kg) 1:6.

 

  •  Take (approx 80 litres) of water in a stirring vessel.

 

  •  Open a gum powder bag and you find a packet of gum compound (chemical) inside the bag, remove the chemical packet and mix in 3 to 4 litres of water in a separate bucket and keep aside.

 

  •  Now put the gum powder in the vessel and stir for approx.  5minute.

 

  • Now slowly add the gum compound (chemical) solution in the vessel and stir for another 20 minutes

 

  • As the mass becomes thick start adding remaining part (approx. 90ltr) of water slowly.

 

  •  Check and set the viscosity “between” 18 to 24sec in ford B4 cup.

(Note: To set the viscosity “between” 18 to 24sec 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 gum)
