The use of
polyether defoamer is common, mainly under the catalytic action of potassium hydroxide, with propylene glycol or glycerol and propylene oxide, ethylene oxide, etc. polymerization to form a powerful defoamer. Characterized by colorless spots, it is suitable for most silicon-free defoamer industries for defoaming and foam inhibition needs. However, in contrast to the characteristics, it also has certain shortcomings. So put into some creative design level, so that some new type of polyether molecular formula enough to be developed out of the product, then you can make polyether defoamer has more excellent characteristics. Polyether defoamer is a kind of defoamer that has a very different block method and chain distance.
The application of polyether defoamer in the textile industry:
Polyether defoamer is added in boiling, bleaching, and washing, which can improve the treatment effect, so it requires good penetration of defoamer, high-temperature resistance, uniform dispersion, and can make the bleaching agent and net washing agent evenly penetrate into the fabric. It cannot form a silicon spot.
Add in the dyeing slurry, eliminate foam, and avoid the formation of color spots, color spots, and color unevenness on the fabric due to foam, and other undesirable phenomena. The process requires an antifoam agent that is resistant to high temperatures and does not affect the beauty of the product. Excessive addition of silicone defoamer is likely to cause uneven dyeing, the phenomenon of silicon spots, and the formation of color spots. And the use of polyether defoamer will not have this phenomenon.
Textile printing with polyether defoamer in the textile printing process, to avoid foam leading to white spots, spots, or making the fabric pattern color uneven, blurred, and other phenomena, so the added defoamer must ensure product quality, can not affect the viscosity of the paste, color appearance, can quickly disperse, strong self-emulsification, low and high viscosity system can maintain a lasting anti-foaming effect.
Notes on the use of
polyether defoamer:
Add polyether defoamer, you need to pay attention to the addition of the amount added. By adding the amount of measurement, so as to determine the specific amount of use, generally will be controlled at one ten-thousandth to one thousandth. In adding such a polyether defoamer, you need to add it first according to the specific situation. You can directly add to the use of the media environment, in addition, you can first dilute a certain ratio of water and then directly added to use.
