In power plant desulfurization, boiler flue gas desulfurization, powder flue gas desulfurization and other processes, the desulfurization technology can be divided into wet, dry and semi-dry desulfurization according to the dry and wet state of absorbent and desulfurization products in the desulfurization process. Wet desulfurization is the use of absorbent solution or slurry in the wet state desulfurization and treatment of desulfurization products, desulfurization reaction speed, simple equipment, high desulfurization efficiency, but serious corrosion, high operation and maintenance costs, resulting in secondary pollution wet desulfurization process mainly include: limestone gypsum method, seawater method, double alkali method, sodium cycle method, magnesium oxide method. Dry desulfurization means that the desulfurization absorption and product treatment are carried out in a dry state. During the desulfurization process, there is no sewage discharge, the equipment is less corroded, and the secondary pollution is less.However, the desulfurization efficiency is low, the reaction speed is slow, and the equipment required is too large. The main dry desulfurization processes mainly include: charged dry absorbent jet desulfurization method, electron beam irradiation method, adsorption method, etc. Semi-dry desulfurization refers to the flue gas desulfurization technology in which the desulfurizer is desulfurized in a dry state and regenerated in a wet state, or desulfurized in a wet state and desulfurized in a dry state. It combines wet and dry desulfurization processes advantages and has broad application prospects. The semi-dry desulfurization processes mainly include: spray drying method, circulating fluidized bed method, humidified ash circulation method, flue injection method, etc.     At present, the power plant desulfurization technology is dominated by wet desulfurization process, while dry and semi-dry desulfurization process are also developing.The operation of the desulfurization device in the desulfurization of the power plant divides the desulfurization ups and downs into several links. Among them, the most prone to foaming problem is the desulfurization tower slurry treatment link, which needs to be treated with defoaming agent for defoaming.   The function and advantage of defoamers Adding a suitable defoamer in the desulfurization process can reduce the surface tension of water, solution, suspension, etc., and effectively prevent the impact of foam on the desulfurization process. At the same time, the special defoamer for desulfurization has good chemical stability and heat resistance, and has a wide range of applications, which can reduce the loss in desulfurization and improve the working efficiency of the entire desulfurization system.   Causes of foam: 1．The active substances contained in the desulfurization slurry have foaming properties 2．The water quality is poor and there are too many impurities in the slur...

  Latex paint is in common use building materials. Because latex paint contains a lot of surfactants, it is easy to produce foam. Much foam will affect the construction, resulting in safety risk and uneven mixing of materials. Surface defects and color differences, affecting the appearance of beauty. The antifoams we produce are good at suppressing foam from manufacturing to the final product.   The role of antifoams in latex paint In the latex paint, the addition of antifoams can deal with the foam that has emerged and inhibit the emergence of new foam. This reduces costs, and better to help the latex paint molecules disperse evenly, making it whiter and more delicate. It can also improve the latex film's strength, water resistance and scrub resistance. Besides, the density of the antifoam is small, and it has suspension, so as to play an anti-settling.   Advantages of our products l It has a stronger bubble breaking effect, faster defoaming speed, less dosage and longer lasting effect; l It has good surface tension, high temperature resistance, and have good compatibility with other liquid; l It is easily dispersed in water and will not cause secondary pollution;     l It has no negative impact on the next process and won't affect the appearance of the product.     Nanjing ANTIFOAM provides you an antifoam agent with good dispersion and strong system stability.

Leather plays many roles in everyday life, such as shoes, bags, clothes, furniture and car interiors. Causes of foam in leather On the one hand, the raw materials used in the leather production process are sheepskin, cowhide or crocodile skin, etc. These materials belong to natural leather,. They are prone to chemical treatment and produce carbon dioxide, which causes foaming. On the other hand, in the production process, air is mixed due to improper operation, which will also cause foaming.   Negative effects of foaming l If the foam is not eliminated in time, the leather surface will not be beautiful. And the existence of the foam will easily cause cracks on the surface, or even damage, affecting the quality of the product.   l Too much foam will make the whole leather look bumpy and feel rough, affecting customers' desire to buy.   l The production of foam will slow down the production progress of leather, extend the production cycle of leather, and produce unnecessary production costs.   l A large amount of foam will remain on the leather production equipment. It will result in erosion of the equipment, affect the efficiency of the use of the equipment, and shorten the service life of the equipment.   Functions of leather antifoam Leather antifoam can dissolve well with leather and it has effective anti-foaming and defoaming effect. At the same time, the use of antifoam can better maintain the durability of the product. Under the conditions of high temperature exposure, leather is less likely to foam. Besides, the addition of antifoam can alsosolve the problem of foam due to operational errors in the production process.   Advantages of our products l Their defoaming speed is faster and the foam suppression time is longer; l They have good water solubility and fast dispersion and can be well dissolved with leather. Moreover, they will not remain on the leather surface after use; l Using our products will not affect the quality of the leather in the later stage, and will not change the basic system and appearance of the leather.     Nanjing ANTIFOAM provides you an antifoam with good dispersion and strong system stability. We can help you better solve the foam problem of Leather. Please contact us anytime if you need.
