And other non-silicone defoamers assilicone defoamers are also subject to restrictions on the use of environmentalconditions. Binding conditions and different defoamer performance liveenvironment to determine the appropriate species. When necessary, it isdesirable foaming liquid sample to simulate the actual conditions of use anddefoaming experiments to determine the amount of anti-foaming agent.
In actual use, the bubbling liquid siliconedefoamers added amount of 1 × 10-6 ~ 100 × 10-6 can getvery good defoaming effect. Beforehand pulp defoamers water or solvent afterdilution. Not only easy to adjust the amount of dilution is added, it can alsoimprove the dispersion effect of the defoamers.
Defoamers added There are four mainmethods.
1. The anti-foaming agent was added priorfoaming solution method, that suds law. Suitable foaming in a closed container.
2. To continuously bubbling liquid droppingmethod.
3. Spray insufflation, for a short time toproduce large amounts of foam applications.
4. Method on the inner wall of thecontainer is coated foaming liquid defoamer for the vessel to be controlledliquid level applications.
When used in medicine, food productsdefoamers, should be strictly in accordance with the relevant regulations andPharmacopeia selection before use should be disinfected, sterilized.
