環氧地坪漆材料增稠、膠化現象原因及解決方法

什么是環氧地坪漆材料增稠、膠化現象?環氧地坪漆材料增稠、膠化現象是指在存儲過程中環氧地坪材料出現黏度增高,直至膠狀的現象。由于溶劑揮發或溶劑使用不當或因氧化聚合等反應使黏度增高的現象稱為增稠。由于漆基與顏料之間的反應,稠度變得特別高,嚴重的呈豆腐狀或塊狀,稱為膠化。膠化、增稠等現象是不可逆的,與觸變現象不同。

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、環氧地坪漆材料增稠、膠化現象的原因

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

1、環氧地坪漆材料沒有完全密封,在存儲過程中溶劑揮發,導致環氧地坪漆材料增稠、膠化。

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.

2、環氧地坪漆色漆所用的顏料與漆基發生反應,如鋅白、鉛白等鹽基性顏料與漆基中的有機酸起反應生成金屬皂,引起增稠、膠化。

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、環氧環氧地坪漆材料溶劑使用不當,例如使用了溶解力不強的稀釋劑就會導致環氧環氧地坪材料增稠、膠化。

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、環氧地坪漆材料增稠、膠化現象預防辦法:

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

1、環氧地坪漆材料包裝桶要完全密封,開蓋未使用完的材料一定要密封好,最好在一周內用完。

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

2、某些漆基應避免選用鹽基性顏料,而以鋅鋇白、鈦白、氧化銻等顏料替代,炭黑的pH值低,通常添加少量的三乙醇胺來克服。

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、環氧地坪漆材料一定要選用適當的溶劑或添加溶解力強的溶劑。

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