Pulp is in the paper making process will be added to the pulp in the gum, filler, colour and other additives modulation into a fibre for papermaking interest floating liquid. Pulp is an organic substance with general colloidal properties, rich in plasticity, can be used as a dye and other chemicals on the fabric transfer agent. In the practical application of pulp, foam problems arise from time to time. These foams are viscous, difficult to eliminate, very much in need of pulp defoamer help. More types of paper pulp, there are mechanical wood pulp, sulphate wood pulp, sulphite wood pulp, waste paper pulp and other four categories. Mechanical wood pulp is the use of mechanical methods of grinding fibre raw materials made of pulp, it occupies an important position in the paper industry. Sulphited wood pulp is made by using a mixture of sodium hydroxide and sodium sulphide as the cooking agent, the paper made, its folding, breaking and tear strength is good; sulphited wood pulp fibres are longer, soft in nature, good toughness, high strength, and has a very good interweaving ability. As the pulp contains a lot of air, a lot of these gases will be retained in the pulp inside, difficult to escape, so it will form a lot of foam; In addition, the pulp contains many lignin polysaccharides, resins, proteins and other organic substances and surface-active substances, is the main reason for the production of foam; due to the mixing operation of machinery and equipment will also lead to the production of foam, the pulp will affect the quality of the pulp. Foam in the pulp will affect the progress of pulp production, resulting in lower production efficiency, but also reduce the density of the pulp, resulting in increased pulp costs; too much foam will make the fibers in the slurry to float up to produce floating pulp, foam and flocculation, resulting in uneven dispersion of pulp on the Internet, so that the quality of the paper is reduced; in addition, the generation of foam will also make the quality of the slurry and the performance of the pulp is affected, resulting in the production of the surface of the paper with pinholes, White spots and other defects. In the face of foam in the pulp, many people will choose the pulp defoamer to solve the foam, the defoamer defoaming, foam inhibition performance is good, can be very good to eliminate all kinds of foam in the size of the pulp, and inhibit the production of subsequent bubbles; water solubility is good, fast dispersion, it can be very good and the pulp soluble, not bleaching oil, no precipitation; resistance to high temperatures, acid and alkali resistance, chemical stability and good, after the use of the pulp will not affect the basic performance of the pulp. It has good chemical stability and will not affect the basic performance of the pulp after use.

Industrial wastewater treatment has always been one of the important issues in the field of environmental protection. With the acceleration of industrialization, industrial wastewater emissions continue to increase, in which sewage is often accompanied by a large number of bubbles. These bubbles will not only affect the normal operation of wastewater treatment equipment, but also may cause some pollution to the environment. Secondly, industrial wastewater often contains a large number of organic substances and suspended solids, these substances can easily lead to high sludge concentration, and the foam in the sewage treatment process will not only affect the treatment effect, but also affect the normal operation of the equipment. Therefore, the use of defoamer is particularly important. Rickman industrial wastewater treatment defoamer has many advantages.

Waterborne coatings have been rapidly developed in various countries by virtue of their green, energy-saving and peace of mind, and ease of use. Waterborne coatings, especially waterborne industrial coatings based on various types of emulsions, need to add a variety of additives in the formulation design process due to the characteristics of the base material itself and the high demand for the surface state of the coating film and the high demand for constructability, in which the choice of defoamer is crucial. If there are more bubbles in the coating it will limit production capacity, affect product quality, cause waste, pollute the environment, and may bring about protection problems. The main reasons for foam generation in water-based coatings are 1, The paint production process mixing bubbles; 2, Paint canning process produces air bubbles. 3, In the construction process to produce air bubbles, such as roller coating or airless spraying, etc.;. 4, The paint in the curing process produces gas; 5, In the construction of porous substrates produce bubbles, such as stone, wood or cement board. The stabilizing factor of air bubbles is generally the role of surfactants. In the process of coating application, surfactants may be the resin base itself, emulsifiers, substrate wetting agents, wetting and dispersing agents and so on. Adding defoamer to water-based coatings is the main method to reduce the foam generated throughout the production and application process, and the main functions of defoamers include defoaming and foam inhibition. There are many varieties of defoamers in use at present, and the defoamers for water-based coatings mainly include mineral oils, organosilicones and polyethers. Mineral oil defoamers are cost-effective, more commonly used, can be used in the vast majority of flat and semi-gloss latex paint, but the effect of breaking the bubble and defoaming is not as good as organosilicon defoamers. Organosilicon defoamer has low surface tension, excellent defoaming and foam inhibition ability, and has little effect on the gloss of the coating film, but when used improperly, it will produce poor recoatability, film shrinkage and other drawbacks. Polyether defoamers are mainly used in systems with higher compatibility requirements, weaker defoaming ability and smaller market share. Through compounding, modification and other technical means can improve the compatibility and anti-foaming performance of the above defoamers. The evaluation of defoamers can be assessed in terms of foam inhibition, defoaming, compatibility, degassing and brushability. The commonly used methods for evaluating the antifoaming performance include: high-speed dispersion method, shaking bottle method, puffing method, shaking method and cyclic puffing method, etc. All of these methods utilize the change of foam volume to assess the performance of antifoaming agents. However, there is no fixed standard for the evaluation of defoamers, and the advantages and disa...
