[performance characteristics]
This product is a high efficiency defoaming agent composed of polymethyl siloxane by special process. It has a strong anti-foam effect, fast dissipation and long lasting. Because of polysiloxane with different chemical properties, this product is not only suitable for the dissipation of the bubble, more suitable for foam under high temperature and low temperature environment, and non-toxic, tasteless, won't cause any pollution to the environment, when using this product defoaming less dosage, low use cost. It is suitable for water - phase and polar solvent phase (such as dimethyl formamide, methanol, ethanol, etc.).
[technical indicators].
Appearance: cream paste.
Solid content: 30%
PH value: 6 ~ 8
[usage]
The bubbles formed in the water system should be soaked in this product, such as: printing and dyeing, washing, paper making and water treatment; Defoaming in the process of biological fermentation; Metal cleaning agent, cutting liquid, and so on, as well as the daily production of low foam, no foam washing powder.
The foam formed in the polar solvent, and the trace water entering the system does not affect its products, can be used in this product, for example, the anti-foam of artificial leather.
[usage and dosage]
This product should be diluted with 5-6 times water (or DMF, etc.) before it is used in the defoaming system, and then it can be used with better dispersion effect. The specific operation method is: firstly, 1 times the amount of water is added to this defoaming agent, and then it is quickly mixed (no lumps are allowed); Add 1 times the amount of water quick stir (block), repeat the operation three times (that is, the water added up to three times), stir after adding the rest of the water at once, then stir, to block shall prevail. When used, the diluent will be added to the bubbling system by about three parts per million.
[precautions].
Water dispersed defoaming agent the original cream, disposable water added too much, will not easily dispersed block formation, therefore, should be taken by several times, less time and water solution of water, keep the system in the condition of relatively high viscosity of dispersion evenly (if use 50 ° hot water dispersion is better), so of defoaming agent dispersion can be quickly dispersed in the foaming system, fast defoaming effect. Because of all sorts of system of foaming medium is different, foaming causes are diverse, complex, so although this product has a wide adaptability, but may not apply to any kind of foaming system, so please, after users do small sample experiment to determine whether this product is suitable for your product defoaming.
[packaging and shipping]
