Usage and dosage

JY-2510 defoamer can be diluted with thickening water. In the process of dilution, the speed of stirring is between 30 to 60 rpm and the time of stirring is recommended for no more than 10 minutes. Please request the company’s customer service department for the specific dilution method. The company accepts no responsibility for any loss which may be incurred by the customer as a result of incorrect usage.

It is suggested that the product is added in a place where the defoamer can disperse easily. Specific application method is as follows:

Pretreatment of textile: Add product directly to the pretreatment system.

Textile dyeing: Add product directly to the cotton dyeing system.

Acrylic size: Pre-dilute the product with 2.5-9 parts of thickening water, then add the defoamer in the acrylic size after the manufacturing of the acrylic size. Or added the product in the process of sizing. The recommended dosage is between 0.1 to 0.5% for the total amount of formula.

Industrial cleaning: Pre-dilute the product with 2.5-9 parts of thickening water, Then added the product in the industrial cleaning as formulation composition. The recommended dosage is between 0.05 to 1% for the total amount of formula.

Sewage treatment: Generally, the product is added where bubbles concentrate, such as the inlets of the aeration tanks or wastewater collection pools. The dosage is 0.5 to 100 ppm, yet the optimum addition level should be preliminarily tested in a laboratory setting.
