    Core tip: Introduction: Driers are one of the main additives for coatings Traditional organic acid soap driers, such as cobalt, manganese, lead, zinc and calcium, are various, some of them are dark, some of them are expensive and some of them are poisonous The rare earth driers developed in recent years can solve the above problems, but only some expensive cobalt naphthenate driers can be obtained The effect of cerium metal on the surface drying of coatings is obvious, but its effect on the surface drying of coatings is still far lower than that of cobalt metal, and its effect on the actual drying of coatings is not as good as that of lanthanum metal Therefore, it is difficult to use cerium rich rare earth drier to replace cobalt drier A new compound drier Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: brief introduction: driers are one of the main additives for paint Traditional organic acid soap driers, such as cobalt, manganese, lead, zinc and calcium, are various, some of them are dark, some of them are expensive and some of them are poisonous The rare earth driers developed in recent years can solve the above problems, but only some expensive cobalt naphthenate driers can be obtained The effect of cerium metal on the surface drying of coatings is obvious, but its effect on the surface drying of coatings is still far lower than that of cobalt metal, and its effect on the actual drying of coatings is not as good as that of lanthanum metal Therefore, it is difficult to use cerium rich rare earth drier to replace cobalt drier The new composite drier is made of high-quality isooctanoic acid and a variety of rare earth metals It does not contain cobalt and lead, and can be used as a new composite drier for coatings alone Features: Performance Comparison: it can be seen from table 1 that, in accordance with the technical indicators, the amount of composite drier is 0.3%, only 1 / 10 of the total amount of original drier (3.4%) Generally, the dosage of composite drier is 0.3% - 0.6% (based on the total paint) When the solid content of alkyd varnish and white alkyd enamel is 55% - 65%, the amount of composite drier is only 0.3% - 0.4% of the total paint; for blue and green paint, the amount of composite drier is 0.45%; for black paint, the amount of composite drier is 0.5 because of the physical adsorption of carbon black pigment %Because of the complexation of pigments and metal ions, the amount of composite drier should not exceed 0.6% Comparison of economic benefits: see Table 2 for the cost comparison between the composite drier and the traditional drier It can be seen from table 2 that the cost of the composite drier is reduced by 20% - 40% no matter the traditional drier system of cobalt, manganese, lead, zinc and calcium or the rare earth cobalt drier system is used (the cost of the composite drier includes the part of the cost that the solvent needs to be supplemented in the coating due to its small amount) In fact, the benefits of using composite drier are not only reflected in reducing coating cost The composite drier has no purple effect of cobalt, and the color of the coating is light The coating prepared by it can still be applied under the conditions of low temperature in winter and high humidity in rainy days In addition, it can be used for paint preparation independently without several driers It is easy to operate and can reduce the operation error 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,
