No matter pulp process or paper making process, many surfactants are essential for the during production. Surfactants used as cooking AIDS can promote the penetration of cooking liquid to fiber raw materials, enhance the removal of lignin and resin from wood or non-wood, and play the role of dispersing resin. The anionic surfactants used as resin remover include sodium dodecyl benzene s...
More and More companies who are traders , know how to choose the type of defoamers in papermaking process. However , how to evaluate defoamer’s performance in papermaking process, they just do some lab in simple test by eye observing the foam. It works but is not comprehensive. In order to evaluate comprehensively, you need to know the air content measure, which is mainly used to detect the ...
In order to improve the cleaning effect and remove impurities from the surface of the steel plate during cleaning, chemical additives such as cleaning agents are added. However, it is easy to produce a lot of foam under high-pressure washing, so it will be used with steel plate cleaning antifoams. The main reason why foam appears during steel plate cleaning is that the steel plate cleaning agent c...
In the pulping and papermaking process, a series of operations after cooking and discharging, such as washing, screening, bleaching, concentration, pulp supply system, surface sizing, coating, black liquor recovery, etc., are all affected by foam to varying degrees. Today Rickman will mainly share with you surface sizing. What is surface sizing? Surface sizing is a procedure in the paper proc...

Drilling fluid defoamers change the physical properties of foam by interfering with and destroying the surface tension of the foam, thereby rapidly disintegrating the foam into liquid form. The main components of defoamers usually include surfactants, anti-bubbling agents, and foam disruptors. These ingredients adsorb to the surface of the foam, reducing the surface tension of the foam and causing...
In construction projects, cement mortar has always belonged to the large dosage and wide use of building materials, consisting of cement, fine aggregate (sand), water, admixtures and additives. When the raw materials of mortar to be proportioned have a large amount of water, inappropriate size of aggregate, and high content of needle-flake particles, coupled with the influence of admixtures, cemen...
