环氧地坪漆材料增稠、胶化现象原因及解决方法

2019-06-22 22:34:06 常州亿创能源科技有限公司 阅读

大发体育什么是材料增稠、胶化现象?材料增稠、胶化现象是指在存储过程中材料出现黏度增高,直至胶状的现象。由于溶剂挥发或溶剂使用不当或因氧化聚合等反应使黏度增高的现象称为增稠。由于漆基与颜料之间的反应,稠度变得特别高,严重的呈豆腐状或块状,称为胶化。胶化、增稠等现象是不可逆的,与触变现象不同。

大发体育What is the phenomenon of thickening and gelatinization of epoxy floor paint material? The phenomenon of thickening and gelatinization of epoxy floor paint material refers to the phenomenon that the viscosity of epoxy floor material increases until gelatinization occurs during storage. Thickening is a phenomenon of increasing viscosity due to solvent volatilization or improper use of solvents or oxidative polymerization. As a result of the reaction between the paint base and the pigment, the consistency becomes very high, serious tofu-like or block-like, called gelatinization. Gelatinization, thickening and other phenomena are irreversible, different from thixotropy.二、漆材料增稠、胶化现象的原因

2. Reasons for Thickening and Gelatinization of Epoxy Floor Paint Material

大发体育1、漆材料没有完全密封,在存储过程中溶剂挥发,导致漆材料增稠、胶化。

1. The epoxy floor paint material is not completely sealed, and the solvent evaporates during storage, which results in the thickening and gelatinization of the epoxy floor paint material.

大发体育2、漆色漆所用的颜料与漆基发生反应,如锌白、铅白等盐基性颜料与漆基中的有机酸起反应生成金属皂,引起增稠、胶化。

2. The pigments used in epoxy floor paint react with the paint base, such as zinc white, lead white and other basic pigments react with organic acids in the paint base to form metal soap, which causes thickening and gelatinization.

3、环氧漆材料溶剂使用不当,例如使用了溶解力不强的稀释剂就会导致环氧材料增稠、胶化。

大发体育3. The improper use of solvents in epoxy floor paint materials, such as the use of diluents with weak solubility, will lead to the thickening and gelatinization of epoxy floor paint materials.三、漆材料增稠、胶化现象预防办法:

大发体育Preventive measures for thickening and gelatinization of epoxy floor paint materials:

1、漆材料包装桶要完全密封,开盖未使用完的材料一定要密封好,最好在一周内用完。

大发体育1. The packaging barrel of epoxy floor paint materials should be completely sealed. The unused materials should be sealed well, preferably within a week.

大发体育2、某些漆基应避免选用盐基性颜料,而以锌钡白、钛白、氧化锑等颜料替代,炭黑的pH值低,通常添加少量的三乙醇胺来克服。

大发体育2. Salt-based pigments should be avoided in some paint bases, and zinc-barium white, titanium white, antimony oxide and other pigments should be replaced. Carbon black has a low pH value, which is usually overcome by adding a small amount of triethanolamine.

3、漆材料一定要选用适当的溶剂或添加溶解力强的溶剂。

大发体育3. Epoxy floor paint materials must choose appropriate solvents or add solvents with strong solubility.
