WHAT IS FIBER CHEMENT? Fiber cement is a composite material made of sand, cement, and cellulose fibers. It is a durable and low-maintenance building material that can be used for siding, roofing, and trim on both interior and exterior surfaces. It is also fire-resistant and insect-proof. Harm of foam for fiber cement board Bubble formation in fiber cement boards can be a serious problem as it can ...
Urban wastewater treatment is the process of eliminating pollutants from surface runoff (storm-water) and household wastewater. The goal of this process is to produce Environment-friendly fluid waste and solid waste suitable for disposal or reuse. Physical, chemical and biological methods can be used in the treatment process to remove physical, chemical and biological pollutant...
Biological water treatment is a solution that eliminates contaminants from wastewater by means of living organisms. This type of treatment is commonly used in industrial settings that generate large volumes of wastewater, such as food processing factories. The solution works because the organisms used in the process consume the contaminants and break them down into harmless by-products. In contras...
Fertilizer is a basic substance to feed every growing crops, usually organic or inorganic.It can provide essential nutrients such as nitrogen, phosphorus, and potassium to plants after adding to the soil. Fertilizers can be used to improve the quality of soil and make crops thrive. Harms of foam for fertilizer/phosphoric acid Foam in fertilizers may lead to harmful effects on crops if not applied ...
Fatty alcohol is aliphatic alcohol with 8 to 22 carbon atomic chains. Fatty alcohol usually has an even number of carbon atoms and a hydroxyl group attached to the end of the carbon chain. One of the raw materials of surfactants used in detergents. The general formula is ROH.The R of alcohol used in detergent is usually a hydrocarbon group of C12~C18. The high carbon fatty alcoholog...
The stability of an emulsion defoamer hinges upon a carefully balanced interplay between specific concentrations of emulsifiers and the application of cutting-edge stabilization techniques. Remarkably, despite the inherently thermodynamically unstable nature of the oily substances within an emulsion, the presence of an optimal quantity of emulsifier stabilizers endows the emulsion with relative st...
Advantage of type defoamers for pulp and paper Type of defoamer Advantage Grease Breaking foam quickly Silicone Fast antifoaming performance Fatty ALohol Strong degassing performance, low unit price, minimal impact on sizing Polyether (ester) Fast defoaming and excellent foam inhibiting performance Harm of excessive foam in pulping process: 1. The generation of foam leads to the decrease of ...
Hazard of bubbling in circulating water treatment (1) Excessive foam leads to thorough sewage treatment, which cannot meet the detection standards of environmental Protection Bureau, and can not be discharged, slowing down the process; (2) Too much foam spills over from the surface, causing serious pollution of the external environment; (3) too much foam, water treatment appearance is too ugly; (4...
