How much do you know about defoamers for papermaking
Paper, ubiquitous in daily life, first appeared in 105 AD and has accompanied human life for over 2000 years now! We all know that the raw materials for papermaking are plants, including trees, bamboo, reeds, sugarcane, etc.
But how was paper made?
Simply put, there are two steps from raw materials to paper.
Step 1: Pulping
Pulping: The paper making raw materials are boiled in the chemical pulp to extract the essence of the raw materials pulp. Due to the fact that the slurry often appears black during the cooking process, it is often referred to as "black water". The composition of black water is complex, and it is also a high temperature cycle state, so the production of foam is inevitable. How to effectively control the production of foam under the conditions of high temperature, high alkali, high agitation and high grease?
The selection of defoamer & antifoam is crucial.
Originating from a unique understanding of "black water", RISE Company has a unique molecular structure of organic silicon defoamer & antifoam for cooking pulp, which can stably control the consumption of pulp per ton between 0.05 and 0.252kg, making it highly cost-effective!
Step 2: Papermaking
Paper making is the process of dispersing pulp into water and using a paper machine to dehydrate and make paper. Due to the white color of the water during the paper making process, it is often referred to as "white water". White water is rich in paper fiber and papermaking additives. It is also in the state of circulating agitation, and foam is inevitable. How to control and introduce the fine foam in "white water" to ensure the quality of paper making?
The selection of defoamer & antifoam is crucial. Derived from a unique understanding of "white water", RISE Company has a unique molecular structure of alcohol ether defoamers for paper making, which can stably control the consumption per ton of paper between 0.11 and 0.285kg, making it highly cost-effective!
In your life, you may not see RISE,
But RISE is right beside you!
