When the selection and use of silicone defoamers should pay attention to the problem of

Before Xiaobian to introduce a silicone defoamers compared with other types of defoamers five characteristics, today we offer silicone defoamers selection and use of some experience and reference proposal. And, like other non-silicone defoamers, silicone defoamers Han Feng Technology is also affected by environmental conditions and different performance defoamers and determine the appropriate species. When necessary, it is desirable foaming liquid sample to simulate the actual conditions of use defoaming experiments and determine the amount of defoamers.
Note: In actual use, add the bubbling liquid silicone defoamers amount 1X10 ^ -6 ~ 100X10 ^ -6 can get a very good defoaming effect, so in advance should defoamers water or solvent (also available bubbling liquid) after dilution. Not only easy to adjust the amount of dilution is added, it can improve the dispersion effect of the defoamers.
Defoamers added methods are mainly four kinds:
1. Jia Dao advance defoamers bubbling liquid method, that suds law. Suitable foaming in a closed container;
2. Continuous dropping of the foaming liquid;
3. Spray insufflation suitable period of time to produce large amounts of foam of occasions;
4. The method of bubbling liquid in the inner wall of the container is coated defoamers, for the need to control the liquid level in the container occasions.
Tip: ? Due to the special nature of the production of silicone defoamers, specific product parameters or recipes call; ? use silicone defoamers used in medicine, food aspect of anti-foaming, should be strictly in accordance with the relevant regulations Pharmacopoeia and selection, before use disinfection and sterilization processing
