Invely-3180 defoamer for paper pulp（black liquor）

It is well known that pulping is the process of separating fiber materials from plants to obtain pulp. In the pulping process, a large amount of foam will be produced, affecting the production efficiency and the quality of the pulp board.

The role of defoamers in the pulp industry is very critical. It is used to prevent various problems caused by foam during the pulp washing process, such as slurry overflow tank, reducing the efficiency of the pump, the formation of deposits on the paper, pulp water filtration Problems, etc.

Invely defoamer 3180 uses innovative silicone chemistry to achieve superior foam suppression. It can be used in black liquor without depositing on paper, improving water filtration performance and effectively helping pul p mills Improve efficiency. Invely-3180 improves production efficiency while reducing total operating costs. Invely-3180 is specially designed for pulp and is also recommended for industrial cleaning, wastewater treatment, pesticides and other applications.

Features:

High content silicone emulsion defoamer
Long-lasting foam suppression under strong alkali and high temperature
Good dispersion in pulp black liquor, improve productivity and pulp quality
Reduce TCO by reducing chemical use, saving water and energy

Dispersion of defoamer in black liquor

Why Foam could be so inconvenient ? A light foam is generally not problematic in most applications however heavy foaming can often lead to various processing problems. These problems range from inaccurate readings from control and measuring equipment such as temperature, level and density controllers to poor mixing of reactants in chemical reaction vessels and products hanging in the foam, all too often leading to losses in production. Finally the presence of foaming can give a bad image of the way a process is operated in the eyes of a customer. The presence of foam in discharged effluent can cause complaints from local people and authorities even if the foam is harmless to people and the environment. How do silicone defoamers work ? Foam is a gas dispersion in a liquid or solid continuous phase. Foam iscreated by the surfactants which are at the air/liquid interface. Therefore air bubbles occur and are stabilised by the surfactants. Today, silicone antifoams are thebest solution to a...

How do we assess antifoam efficiency ?

How do we assess antifoam efficiency ? Quality of an antifoam is given by two main characteristics : • Knockdown ability or shock effect :Meaning the speed to destroy an existing foam. • Persistence or durability : Meaning the efficiency over time. These two parameters can be assessed by several tests. The main test is the bubbling method. A graduated column with a glass frit in the bottom is required. Foaming water is poured in the column and air at constant flowrate is introduced through the glass frit in the column. Foam is generated by the air and starts to travel up the column. At a determined level of foam, antifoam is injected. By this method several antifoaming agents can be tested. A graph reporting foam height vs time is very helpful to establish the knockdown ability and the persistence for each product. The selected antifoam is the product with the best compromise between shock effect and durability Environmental performance Silicone antifo...
