FAQ

My grandpa died from Alzheimer’s disease, I didn't know what it was but I came across something slightly disturbing. There were several blog and research sites linking Sodium Aluminum Phosphate ((you know the stuff in bisquick pancake batter stuff or maybe eggo waffles)) what bothered me is that two root words of that ingredient bothers me aluminum Phosphate ((is that like phospherous, as in phospherous paint...didn't that turn out bad to the body?)) If so maybe I need a second opinion or ensurance that it is real or not if it is I'm not eating pancakes again. Please help answer this.

Sodium aluminum phosphate is an ingredient in baking powder, which is used as a leavening agent (creates the holes / airspaces) in products like waffles, pancakes, cakes, breads. Only a small amount is used, so I'm not personally worried about the amount--I don't eat things like pancakes, waffles, cakes very often. Most breads tend to use yeast as the leavening agent, which means they do not use baking powder. I suppose waffles, pancakes, and cakes could be made with yeast as a leavening agent, but it would be a more time consuming (and complicated) process. (Iirc, some pancakes are made with sourdough, which uses yeast as a leavening agent.) By the way, making your own pancakes or waffles at home does not solve the problem unless you eliminate baking powder and use yeast instead. I've never heard of phosphorus paint, or a danger from it--the one I remember is lead paint and the dangers from it. Maybe I'm just getting old and not keeping up with all the latest hazards. To conclude, I'm not worried about the small amounts of sodium aluminum phosphate that I may get from eating products made with baking powder. Maybe if I ate large stacks of pancakes every day, I'd be more concerned, but I think the bigger concern in that case would be a lack of variety (and various trace nutrients)in my diet.

It depends on the specific material being compared. Generally, aluminum coils tend to be more expensive than some other coil materials, such as copper or steel. However, the cost can vary depending on factors like the coil size, thickness, and supplier.

To guarantee the elimination of any contaminants or impurities, aluminum coils undergo a series of steps for cleaning prior to further processing. The cleaning process entails the utilization of chemical solutions and mechanical techniques. Initially, the coils are immersed in a degreaser or cleaning solution to dissolve and eradicate any oils, greases, or dirt present on the surface. This stage is essential in eradicating organic contaminants that may hinder subsequent processes. Following the soaking, the coils typically undergo a high-pressure water rinse to eliminate any remaining residues or particles. This step aids in dislodging and flushing out loosened contaminants from the coil surface. In certain instances, a combination of chemical cleaning and mechanical scrubbing or brushing may be employed to effectively eliminate stubborn or baked-on contaminants. This method is particularly beneficial for coils exposed to harsh environmental conditions or industrial processes. Once the coils have been cleaned, they are typically rinsed again to ensure complete removal of any cleaning agents or residues. This is crucial to prevent any adverse effects or interference with subsequent processing stages. Overall, the cleaning of aluminum coils prior to further processing plays a vital role in achieving high-quality end products. It ensures impurity removal, enhances the surface finish, and improves the overall performance and lifespan of the finished aluminum products.

After installation, it is indeed possible to paint or coat aluminum coils. Aluminum, being a versatile material, lends itself well to painting or coating in order to improve its aesthetics or offer extra safeguarding. Opting to paint or coat aluminum coils subsequent to installation can effectively thwart corrosion, enhance durability, and yield a personalized finish. The selection of paint or coating hinges upon the specific necessities and desired results. Prior to applying any paint or coating, it is crucial to thoroughly clean and prepare the aluminum surface to ensure strong adhesion and long-lasting results.

Yes, aluminum coils can be used in HVAC systems. In fact, aluminum coils are increasingly becoming a popular choice in the HVAC industry due to their numerous benefits. Compared to traditional copper coils, aluminum coils are more corrosion-resistant and can withstand harsh weather conditions, making them ideal for outdoor units. They are also lighter in weight, making installation and transportation easier. Additionally, aluminum coils are more cost-effective and environmentally friendly, as aluminum is a highly recyclable material. Overall, aluminum coils offer improved efficiency, durability, and cost savings, making them a suitable choice for HVAC systems.

Aluminum coils have several types of end conditions, which determine how the ends of the coil are prepared for different applications. Some common end conditions for aluminum coils are as follows: 1. Mill Finish: This is the most basic and widely used end condition for aluminum coils. In mill finish, the coil ends are left untouched after coming off the rolling mill, without any additional processing or finishing. This end condition is suitable for applications where the appearance of the ends is not crucial. 2. Trimmed or Sheared: In this end condition, the coil ends are trimmed or sheared to eliminate any uneven or rough edges. This results in clean and smooth ends, which are often necessary for applications that require precise fitting or appearance. 3. Slit: Slitting refers to cutting an aluminum coil into narrower strips or coils. Slitting is commonly done to customize the width of the coil according to specific requirements. The ends of slit coils can have either mill finish or trimmed ends, depending on the desired application. 4. Recoiled: Recoiling involves rewinding a coil into a smaller or larger coil diameter. This end condition is frequently employed when smaller coils are needed for storage, transportation, or further processing. Recoiling can be done with or without additional trimming or shearing of the ends. 5. Flattened: Flattening is the process of unrolling and flattening the coil to create a sheet or plate. This end condition is often used when the aluminum is intended for further fabrication, such as stamping, forming, or cutting into specific shapes or sizes. The ends of flattened coils are typically trimmed to ensure a clean edge. It is important to note that the specific end condition required for aluminum coils may vary depending on the intended application and customer specifications. Different industries and uses may have unique end condition requirements to ensure optimal performance and appearance of the aluminum coils.

There are several advantages of using aluminum coils in HVAC systems. Firstly, aluminum coils are significantly lighter compared to traditional copper coils. This makes them easier to handle and install, reducing the overall labor and transportation costs. Additionally, the lighter weight of aluminum coils puts less stress on the HVAC system, resulting in less wear and tear over time. Another advantage of aluminum coils is their superior resistance to corrosion. Aluminum is naturally resistant to rust and oxidation, which can prolong the lifespan of the coils and enhance the overall durability of the HVAC system. This resistance to corrosion also helps maintain the efficiency of the system, as the coils remain clean and free from clogs caused by debris buildup. Moreover, aluminum coils have excellent heat transfer properties. They can efficiently absorb and release heat, allowing the HVAC system to cool or heat the air more effectively. This improved heat transfer efficiency can result in energy savings and reduced operating costs, as the system requires less energy to achieve the desired temperature. Furthermore, aluminum coils are more environmentally friendly compared to copper coils. Aluminum is a highly recyclable material, and using aluminum coils can contribute to reducing waste and conserving resources. Additionally, the process of manufacturing aluminum coils requires less energy and produces fewer greenhouse gas emissions, making it a more sustainable choice for HVAC systems. In summary, the advantages of using aluminum coils in HVAC systems include lighter weight, corrosion resistance, superior heat transfer properties, energy efficiency, and environmental sustainability. These benefits make aluminum coils a preferred choice for many HVAC professionals and homeowners alike.
