Leather ink defoamer is a special chemical specially designed to solve the foaming problem generated during the production of leather ink. It can effectively eliminate foam, improve the quality and performance of leather ink, and provide a better guarantee for the production of leather products. So, how to use it properlyDefoamer for leather inksWhat about it?This article will introduce it to you in detail.
First of all, we need to understand how leather ink defoamers work. In the production process of leather ink, due to various reasons, such as stirring, grinding, etc., it is easy to produce a large number of bubbles. These bubbles will not only affect the fluidity of the ink, but also reduce the quality of the print and even cause the print to fail. Leather ink defoamers eliminate foam by breaking the surface tension of the bubbles, causing the bubbles to burst quickly.
Next, let's take a look at the use of leather ink defoamer:
1.Determine the amount of addition: Before using the defoamer of leather ink, it is necessary to determine the appropriate amount of addition according to the actual production situation and the degree of foaming. In general, the amount of defoamer added is about 01% -1%。The specific amount of addition can be adjusted according to the actual effect.
2.Addition method: Leather ink defoamer can be added directly to the ink, or it can be diluted with water before adding. During the addition process, ensure that the defoamer is well mixed with the ink for best results.
3.Dosing time: Leather ink defoamer should be added at the appropriate stage in the ink production process. In general, it can be added before or after stirring, grinding, and other foam-producing processes. Adding too early may cause the defoamer to not work adequately, and adding too late may affect productivity.
4.Precautions: When using leather ink defoamer, the following points should be noted:
1) Choose the right defoamer: There are many types of defoamers on the market, and the appropriate defoamer should be selected according to the specific composition and production process of leather ink.
2) Avoid excessive use: Although the defoamer can effectively eliminate foam, excessive use may lead to a decrease in ink performance and affect the printing quality. Therefore, the amount of addition should be strictly controlled during use.
3) Storage and use: Leather ink defoamer should be stored in a cool, dry place, away from direct sunlight and high temperatures. During use, you should follow the relevant safety regulations and wear protective equipment.
