What is paper tube glue defoamer and how to use defoamer in the paper tube glue correctly?
The paper tuber adhesive is commonly known as paper tube glue, paper tube glue, etc. It is a special adhesive for making various paper tubes, paper barrels, paper cans and related paper products. Paper, cloth, plastic film, metal foil and other thin soft materials, commonly used paper tube (paper tube) is wound into bundles to make a paper roll core-shaped finished product. These paper tubes are generally rolled and bonded by kraft paper or other raw paper, and the adhesive used is called paper tube glue.
In the production of paper tube glue, PVA, vinyl acetate, polyacrylamide, ethylene glycol, etc. are added in the production. Most of these additives are surfactants, and foams are easily generated when mechanically stirred or subjected to shearing. The presence of foam can have a negative impact on the production process. If the foam is not properly controlled, it will seriously affect the operation of the production and the quality of the product. The addition of paper tube glue defoamer to control the foam is easy to use, easy to operate, and does not change the production process, and is very popular among paper tube glue manufacturers.
In order to make you better understand, I share our customer case here.
So please could you check below details:

Product Code: INVELY-263

Performance characteristics:
  • Good dispersion, good suppression of bubbles;
  • It is suitable for adding and using in viscous and easy foaming system.
paper defoamer

Comparison INVELY-263 and customer sample by air drum in 1% PVA solution

Test condition

  • Temperature: 80 ° C
  • Dosage: drop the tip of the syringe
  • Raw material: 100 ml 1% PVA solution.

Test Method

Wash the air drum test instrument, add 100ml of foaming solution, add defoamer, and then record the foam height at different time periods at the set flow rate (maximum single head flow rate) and temperature. Comparing the defoaming performance of the sample by recording the change in the volume V of the foam over time;

Test Result

defoamer

Conclusion

In 1% PVA solution, the defoaming performance of INVELY-263 is better than customer sample at 80 °C, meeting customer requirements.
Paper tube glue defoamer is made from mineral oil and polyether ester.  It can quickly eliminate the large bubble produced in the production of paper tube glue. It has fast defoaming and foam suppression. The advantages of long, good leveling and low dosage will not affect the product even if it is used excessively.

Defoamer Test Method

Defoamer testing methods are divided into dynamic defoaming and static defoaming tests. If your foaming environment is different, the recommended test methods are different. There are three main types of foam experiments to characterize the activity of defoamers. Persistence. As we have different experimental conditions in different laboratories and the experiments used in our research to obtain results from existing literature, we will introduce these experiments below. Other methods are sometimes used depending on the particular application. 1． Ross-Miles Foam Tester   Features: Tested for strong foaming environments. This experiment is widely used for characterization        (1) Foaming of surfactant solution        (2) Research and application of foam stability in the presence of defoamer In the foaming system, the defoaming performance test was carried out by circulating bubbling by a Ros...

How to control foam and defoaming in the papermaking ?

Foam is always a thorny issue in the pulp&paper industry. Foaming reasons   Once liquid which contain a surfactant or this kind of liquid having a large viscosity is agitated, a large amount of foam which is not easily disappeared is often produced. The reasons why these bubbles are more stable and not easy to disappear are as follows: n   Film elasticity The ability of the liquid film to resist local thinning during the general thinning process is film elasticity. When the liquid film has a thin point, this point is a possible breakage. However, when this is further stretched, the surfactant molecules in this part will be more reduced, and the increase in surface tension will result in a force imbalance, and the surrounding surface will be moved toward a thin point to balance the surface. tension. The movement of the surface layer pulls the liquid of the lower layer together, thus preventing further thinning of the initial weakness and, in turn, foam ruptu...

Why is there bubble in sewage treatment? What are the hazards of these bubbles? How to eliminate these bubbles?

Why is there bubble in sewage treatment? What are the hazards of these bubbles? How to eliminate these bubbles? In the process of sewage treatment, I believe that everyone often encounters a large amount of foam in the biochemical pool, and if it is at rest, it will overflow from the pool, causing serious pollution of the external pool wall of the external equipment, which will deteriorate the operating conditions. Affected  the surrounding environment Type of foam in sewage treatment 1.    Initial bubble In the initial stage of aeration tank start, the sludge in the aeration tank is not suitable for the water quality of the sewage, and is not suitable for the growth environment, and foam is easily formed. As the sludge adapts to water quality, the foam will decrease. At the beginning of the aeration tank start-up, the sludge is relatively small, the sludge load is high, and foam is easily generated. After the amount of sludge increases, the foam will gradua...
