  Blistering of cement mortar is a relatively common problem. Foaming of cement mortar can easily lead to surface roughness, cracking, internal hollowing, overall looseness or low overall compressive strength, etc., which will affect the compactness and firmness of the entire component, resulting in poor construction effect. If harmful foam exists in the cement mortar, it is easy to affect the quality of the cement mortar components. If you find the right method, the foam in the cement mortar system is relatively easy to eliminate. A common, simple and convenient treatment method is to add a cement mortar defoamer. The cement mortar defoamer is mainly designed for the foaming characteristics of the cement mortar mixing process. The use of this product can effectively control the generation of foam in the cement mortar system and make the concrete components more compact and bright. The cement mortar defoamer is a defoamer synthesized by polyether and other ingredients, and it is suitable for defoaming under the conditions of strong acid and strong alkali.     Hazards of cement mortar foaming: 1. Foam will cause air to appear in the cement mortar product and affect the firmness of the product. 2. Foam will affect the dispersion performance, plasticization performance and flow performance of cement mortar products. 3. Foam will affect the appearance and strength of cement mortar products, resulting in honeycomb-like appearance on the surface and substandard strength. 4. Foam will lead to a decline in the quality of cement mortar products, affecting the fireproof, moisture-proof, anti-corrosion, heat-resistant, and cold-resistant properties of cement mortar.   Advantages of cement mortar defoamer: 1. No matter in the case of high temperature or low temperature, the cement mortar defoamer can be applied, and it can still maintain high-efficiency and high-speed defoaming, less dosage and good dispersibility. 2. In the process of construction and production of building materials, effectively control the generation of foam in the cement mortar system, so that the concrete components are more complete, dense and bright. 3. The cement mortar defoamer is non-toxic, odorless, harmless to human health, and conducive to production safety. 4. The cement mortar defoamer can also be applied to defoaming in the production process of mineral pulp, calcium silicate board, concrete, water reducing agent, asbestos tile, putty powder and reinforcing agent.   How to use cement mortar defoamer: Reasonable addition of cement mortar defoamer during use can improve the compactness of cement mortar and make the strength better after hardening. The specific additive amount can be determined according to the amount of foaming at that time. If the amount of foam is too much, the dosage can be increased appropriately. At the same time, before the application of the defoamer, a small part of the cement can be taken for the addition experiment to avoid im...

Defoamer is made from a variety of special polyethers by composite technology, which has good functions of defoaming and defoaming and high shear resistance. After adding, it does not affect the appearance of dishwashing liquid, does not bleach oil, does not break milk, does not float, and does not produce residue hanging on the wall. Post-processing without any adverse effects, environmental protection type. It has the effect of rapid defoaming and long-term defoaming. It does not contain organic solvent, not invade corrosion equipment, and not affect the solderability. Dish soap is a daily use in our daily life, is a good helper in our daily life decontamination. But his production process is not as simple as we thought. Due to surfactants, equipment, stirring, production environment and other reasons will lead to a large number of foam generation. This will affect the consistency and quality of the product, but also slow down the production process, resulting in an increase in costs. This is where dish soap defoamer comes in. The harm of foam in the production of dish soap: 1.It will reduce the quality of the product effect, affect cleanliness. 2.It is not easy to clean for the fiber foam with many gaps, it will also delay the cleaning time and increase the cost. 3.The foam will affect the visibility of the cleaned surface, it is not conducive to observing the degree of cleaning. 4.The foam overflow cleaning system, resulting in environmental pollution. 5.The foam will cause cleaning equipment easy to damage. 6.It will affect the progress of production. 7.It will cause multiple washing, resulting in an increase in costs and waste of resources. Physical causes of foaming: 1.Mixing is not standardized. 2.The production workshop temperature does not meet the production requirements. 3.The equipment power is not suitable. Chemical causes of foaming: 1.There are foamable substances in raw materials. 2.The increase of other auxiliary chemical reaction. 3.The water quality is soft. Reverse solubility: Due to the molecule contains polyether chain segments, it has the turbidity point characteristics of polyether defoamer, and can easily select the suitable polyether defoamer based on the temperature requirements of the system defoamer. Self-emulsion: The hydrophobic and hydrophilic properties of siloxane and polyether are different. When polyether modified silicone defoamer is added to solvent, polyether chain segment extends outside and polysiloxane chain segment curls inside. The dispersion that results is what's called "Self-emulsion." Under the action of self-emulsion, the defoamer can be quickly and evenly dispersed in the foaming solution, and the stability is more prominent. It is beneficial to give full play to the defoaming function. By adjusting the proportion of polyether segment and siloxane segment, the defoamer can be applied to foaming solutions with different properties.  

Nowadays, I believe that most enterprises and factories are very concerned about environmental protection, and they use circulating water treatment systems to treat sewage. During the continuous operation of the circulating water system in the circulating water treatment process, a large number of actinomycetes and filamentous bacteria appear in the water body, and the air introduced by stirring and stirring will naturally appear, such as (proteins, polysaccharides, including other water-based systems containing surface active components of circulating water agents). The foam is mostly yellowish brown and is not easy to handle.  The foaming of circulating water treatment will directly affect the normal operation of the water treatment system, so most factories will use circulating water treatment defoamer for defoaming. Circulating water treatment defoamer can be said to be a low-cost and simple solution. But do you really understand the use of circulating water treatment defoamer? The following is for everyone to sort out some of the use of circulating water treatment defoamer and matters needing attention, let's take a look.     The use of circulating water treatment defoamer: 1) It is recommended to dilute 1-3 times with water or solvent (also available as foaming solution) before use. Drop addition. In the foam more places we drop the defoamer, so that the use of defoamer can be limited. 2)Concentrated drip, flow or spray in the place where the foam is concentrated, and directly add at the mouth of the pool with good sewage flow. The recommended amount is 30-300PPM. Precautions for circulating water treatment defoamer: When using circulating water treatment defoamer, the amount does not need to be too much. Only 0.05%~0.1%, adding too much is also a waste. In the process of dilution, it can not be diluted too much.When the solid content reaches more than 5%, the defoaming effect of circulating water treatment defoaming agent will be significantly reduced, and more defoaming agent needs to be added to achieve the defoaming effect.So it is not worth the loss! If it is to be used immediately when diluted or to be stored for a long time after dilution, remember to add a stabilizer. Circulating water treatment defoamer is a highly efficient defoamer. It is characterized by fast defoaming speed, long time of defoaming, high efficiency, low dosage, and non-toxic, no corrosion, no adverse side effects. Easily dispersed in water, it can be well compatible with liquid products, not easy to break milk bleaching oil.
