DEFOAMER IOTA xpj-29

PRODUCT DESCRIPTION

IOTA xpj-29 defoamer is a dilutable defoamer, which is used in conventional surfactants and polymer foaming systems; it is recommended to use industries for textile printing and dyeing (pretreatment and cotton dyeing), sewage treatment, and emulsion polymerization , pesticide formulation synthesis, etc.

FEATURES

● The substance components of the antifoam do not contain the substances listed in the SVHC list of the REACH Regulation.

● Antifoaming agent component does not contain NP, APEO.

● Fast defoaming speed in application system (normal temperature -80 ℃).

● Good stability in alkaline environment (pH 8.0-11.0)

COMPOSITION

● Composed of polysiloxane, modified polysiloxane, silica, dispersing agent, and stabilizing agent.

TYPICAL PROPERTIES

HOW TO USE

● IOTA xpj-29  Antifoam 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 antifoam can disperse easily.

PACKAGE AND STORAGE

The product is available in 25kg, 120kg and 1000kg plastic buckets; sizes can be customized according to special requirements. This product can be stored as a normal chemical, away from heat sources and direct sunlight. No exposure to rain. Keep away from flame. Don’t add acid, alkali, salt and other corrosive substances to this product.  Ensure the container is sealed after using. If this product begins to stratify after long storage, stir it evenly at 30 to 60 rpm. This product may freeze under 0℃ (32℉); if this happens, stir well after defrosting the antifoam at a rate of 30 to 60 rpm. In these cases, stirring will not affect the performance of the product if carried out at the recommended speed. When stored between 5 and 40℃ (41-104℉) in the original unopened containers, the product is usable 9  months from the date of manufacture.

Attachment 1:

Defoaming rate(ml/s) >75

Inhibition rate(ml/s) >4

The above is obtained by the data laboratory test, the data is for reference only1. Test Conditions

Test temperature: 25 ° C

Test medium type: standard foaming liquid (GB/T 26527-2011)

Test medium addition: 100g

Defoamer use method: Direct addition of antifoam stock solution

Defoamer added amount: 0.1g

Testing method:

Take 100g of standard foaming liquid in 250ml sample bottle, heat it to the test temperature in water bath, then add the specified amount of defoamer; place the sample bottle on the vertical oscillator; set the parameters: frequency is 450rpm/min, amplitude is 30mm; respectively oscillate the plastic bottle for different time; After each oscillation stop, record the time t' of' the foam disappeared to see most of the liquid surface, and the foam volume after the shaking of the blank standard solution was recorded as V.

Elimination and suppression rate calculation method

The ratio of the foam volume V formed by vertically oscillating the blank foaming liquid to the defoaming time t' of each oscillation after the addition of the antifoaming agent. The data of vertical oscillation for 1 min is recorded as the defoaming rate, and the data of vertical oscillation for 5 min is the foam suppression rate.
