Do you make plastic or mine it?
Plastics by definition are synthetic polymers, so we must make them. However the ingredients used to make many of them come from petroleum, which is mined by drilling. However many newer plastics are made from ingredients produced by plants, which can be grown as crops on farms.
Before modern plastics man used many natural polymers for similar purposes to those which we use modern plastics for today. A few are:
What is the purpose of using brine in soap manufacturing?
Brine is used in soap manufacturing as a salt solution that helps improve the hardness and quality of the soap bars. It also helps accelerate the saponification process, leading to faster soap production. Additionally, brine can enhance lather and cleansing properties of the soap.
Is it bad to put a carbonated drink in a stainless steel container?
It is not recommended to put a carbonated drink in a stainless steel container for an extended period of time as the pressure from the carbonation could build up and potentially cause the container to leak or release the pressure suddenly when opened, leading to spillage. It is better to use containers designed for carbonated drinks with pressure release valves to avoid this issue.

Sand is the main ingredient, providing silica for the glass structure, while soda ash and limestone are added to lower the melting point of the mixture. Cullet is often used to supplement raw materials, reducing energy consumption and environmental impact.
How much aluminum is there in aluminum panel?
Aluminium panels are made in various types: They can be "All-Aluminium" (meaning the panel could simply be an aluminum slab or a sheet of large thickness) or they could be composite panels where aluminum sheets are combined with other materials such as plastics, mineral fibers, or hard foam.
Technically speaking, most aluminum sheets that are used in making panels are actually aluminum alloys (which means that some other metals in very small amounts have been added to the aluminum in order to strengthen it and allow it to acquire important properties). Different alloys have different aluminum content.
To calculate how much aluminum is present in a panel, you would first need to identify your Alloy, and then have 3 pieces of information:
1. The Density of your aluminum alloy.
2. The Thickness of your aluminum panel.
3. The Surface Area of your aluminum panel.
For example, take a 1m2 panel of aluminum of alloy AA3003 and a thickness of 1.0mm. To calculate the amount of aluminum (by weight) in that panel, we use the above 3 pieces of information as follows:
Weight of Aluminium = Density x (Thickness x Length x Width)
Tip: Make sure that the units of measurement all match.
(e.g. If you use "Kg." for Weight, then make sure you convert "millimeters-mm" to "meters-m" before applying the formula).
Material used for making dies for pressure die casting of aluminium alloys?
H13 steel is commonly used for making dies for pressure die casting of aluminum alloys due to its high strength, excellent thermal conductivity, and wear resistance properties.

What are the materials used in the manufacture of ldr?
Light-dependent resistors (LDRs) are typically made using semiconductor materials such as cadmium sulfide (CdS) or lead sulfide (PbS). These materials exhibit changes in resistance based on the intensity of light they are exposed to, making them ideal for light sensing applications. LDRs are commonly used in electronic devices to control the amount of light reaching a sensor or to trigger certain actions based on light levels.
Where does lead for a pencil come from?
Lead has never been used in pencils. The 'lead' in pencils is graphite, a form of carbon, mixed with clay.
Modern pencils are the descendants of ancient writing instruments. In ancient Rome, scribes wrote on papyrus (an early form of paper) with a thin metal rod called a stylus, which left a light but readable mark. The ones made of lead worked best.
When pieces of rock from a mineral deposit in England were found to be good for marking sheep, the people presumed it was a lead deposit. Then the pieces were made into the first pencils. Chemists said the deposit was actually graphite, a form of carbon, but 'lead pencils' were so popular that the name is still used to this day.
How many companies are ISO 9001 certified in Kenya?
As of 2021, there are over 300 companies in Kenya that are ISO 9001 certified. The number may vary as new companies seek certification and existing certifications expire.
What is the difference between Japanese AUS 8A Stainless and 440 stainless steel?
AUS 8A is a Japanese stainless steel known for its corrosion resistance and toughness, while 440 stainless steel is a high-carbon stainless steel often used in knife blades due to its hardness and wear resistance. AUS 8A is easier to sharpen but may not hold an edge as well as 440 stainless steel.
Lead pencils are good for everyday writing and drawing tasks due to their versatility and ease of use. They can produce dark or light lines depending on the pressure applied, and mistakes can be easily erased with an eraser. However, they may not be ideal for precision work or long-lasting artwork, as the graphite can smudge and fade over time.
Sal soda, also known as sodium carbonate, is commonly used as a cleaning agent due to its ability to cut through grease and grime. It can be found in household cleaners, laundry detergents, and even as a water softener. Additionally, it is sometimes used in cooking and baking as a leavening agent.
