    Core tip: the word "thixotropy" comes from two Greek words, which literally means "one touch is change" That is to say, because of stirring or shaking, its viscosity, that is, the reduced flow property, is called thixotropy Latex coatings generally show thixotropic flow When subjected to external shear force, the consistency of the coating decreases, while the fluidity increases This thixotropy is usually caused by the failure of some structures in loose combination, and this kind of structure is produced when it is standing (such as during storage), and it is broken up under the action of stress Often consciously Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Paint Home News: "thixotropy" comes from two Greek words, which literally means "one touch is change" That is to say, because of stirring or shaking, its viscosity, that is, the reduced flow property, is called thixotropy Latex coatings generally show thixotropic flow When subjected to external shear force, the consistency of the coating decreases, while the fluidity increases This thixotropy is usually caused by the failure of some structures in loose combination, and this kind of structure is produced when it is standing (such as during storage), and it is broken up under the action of stress The thixotropic structure of the coating system is often consciously produced Adding thickener to the system will make the latex coating thixotropic, which is very important In high shear rate (construction), low viscosity is conducive to paint flow, convenient for construction, reduce brush marks; in low shear rate (before or after construction), high viscosity can prevent settlement or sagging The thixotropic flow of latex coating caused by adding thickener can be attributed to the three-dimensional network structure formed inside the coating Latex particles, pigment particles as dispersed particles and thickener are the constituent factors of the three-dimensional network structure Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
