Antifoam is a type of chemical additive used in the pulp and paper industry to reduce foam formation during the pulping process. It is typically added to the pulp slurry prior to entering the stock chest or paper machine. Antifoam works by forming a thin film on the surface of bubbles, which reduces their surface tension and prevents them from coalescing into larger foam bubbles. This helps mainta...
What processes is waste treatment? 1. Collection and Transportation: This is the first step in waste treatment, where waste is collected from its source and transported to a treatment facility. 2. Sorting and Separation: In this step, the collected waste is sorted into different categories such as organic, recyclable, hazardous, etc. for further processing. 3. Pre-treatment: This involves breaking...
Foaming can cause harm to textiles in a number of ways. Foaming agents can cause the fabric to become brittle and prone to tearing, as well as discoloration. Foaming agents can also reduce the breathability of fabrics, making them less comfortable and more prone to trapping heat and moisture. In addition, foaming agents can damage the fibers of the fabric, leading to pilling and fading over time. ...
Harm of foam: Foam in cement mortar can reduce the strength of the mortar, reduce its water-resistance, and increase its permeability. This can lead to structural damage over time due to water infiltration, which can cause cracking and spalling of the mortar. Foam also reduces the bond between the cement and aggregate, resulting in a weaker mortar. In addition, foam can trap air bubbles in the mor...
Harm of oil drilling: The environmental harm of oil drilling can be significant. Oil spills can occur during the extraction process, which can contaminate water sources and harm marine life. Additionally, air pollution from burning fossil fuels is a major source of air pollution and greenhouse gas emissions. The construction of oil rigs also disrupts ecosystems, destroys habitats, and can cause lo...
What is delay coking? Delay coking is a process used in petroleum refineries to upgrade heavy residual oils into lighter products such as gasoline and diesel fuel. It involves heating the residual oil to very high temperatures in a coker unit, which causes the oil to break down into smaller molecules that can be more easily processed into lighter products. The process is called “delay” because the...
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 ...
What is Wet Process Phosphoric Acid? Wet process phosphoric acid production is a process used to produce phosphoric acid from phosphate rock. It involves the reaction of sulfuric acid with phosphate rock, which produces phosphoric acid and calcium sulfate (gypsum). The gypsum is then separated from the phosphoric acid by filtration or centrifugation. The resulting phosphoric acid can be used in va...
