There is a noticeable shortfall of equipment and tools meant for combatting the spread of the virus. 3D printers are now used to produce this equipment in bulk with a view to reducing the shortages being experienced. This article looks at those areas where the use of 3D printers have proven pivotal.

Production of medical masks

Medical masks remain one of the most vital equipment used in curbing the spread of the virus. Unfortunately, the medical masks are not sufficient as desired; this has become a dilemma. As a matter of fact, some countries have restricted the use of medical masks to only medical personnel. N95 masks are effective in keeping out viral particles from entering openings on the face. 3D printers are used in producing these masks in bulk to ensure it becomes sufficient.

Personal protective equipment

Medical personnel is at the forefront of the fight against the spread of the pandemic. These medical personnel needs some sort of protective wears to ensure they don’t get infected. Protective equipment includes; gloves, goggles and face shields. So many countries have resorted to the use of 3D printers in producing this equipment in bulk. It’s no gainsaying that the sufficiency of these protective equipment has helped keep health attendants safe from getting infected.

Ventilator parts

The corona virus attacks the respiratory tracts of its victims and they often find it difficult to breathe on their own. Ventilators help these patients to breathe well through mechanical means. One major issue that arose during the early days of COVID-19 was the shortage of ventilators around the world. Many companies took the initiative to address this shortfall by printing the parts of the ventilator. The use of 3D printers in creating ventilator parts resulted in the wide distribution of ventilators across the world.

Test kits

Certain tests are carried out on potential patients to determine their status. One of the many kits used include swab kits that are often found in testing labs. Several other components of testing are also produced using 3D printers.

Other applications

The coronavirus settles on surfaces touched by an infected person, many people are bound to contract the virus by touching these surfaces. Health authorities have advised against situations where people have to touch items in public areas; this is where 3D printers come into play. The printers are used to create items that are placed on public utility items like ATM and doorknobs, and even on cosplay, right, 3D printing for cosplay is real.

Final Thought

A motor unit of any kind can generate motion. It converts electrical energy into mechanical energy. Motors are widely used, and you might be surprised at how common they are. They are almost everywhere in our surroundings from our computers, kitchen appliances, toys, switches, hairdryers, microwaves, etc. Motors can be classified among the most significant inventions. Different current (DC) or alternating current (AC) are used to run the motor, and both have advantages and disadvantages. There are many types of motors, and also customization is available. You can check out more on motors on a Stepper motor gearbox. Other than stepper motors, in this write-up, we will look at the types of motors in this extract.

Types of motors

AC motor

It is a motor that uses alternating current to operate. There are two types of AC motors, i.e.,

a. Synchronous motor

It does not rely on slip induction for it to run. It uses permanent magnets on an independently excited rotor winding. The torque it produces is usually synchronized in speed. It is ideal for driving equipment at a constant rate.

b. Asynchronous  motor or an induction motor

A stator winding uses electromagnetic induction after which electric currents are produced in the rotor; thus, torque is produced. There are two types of induction motors.

• Single-phase induction motor-Used for small loads like home appliances.
• Three-phase induction motors-This are mainly used in industries or big manufacturing plants.

DC motor

It is an electric motor that converts current from electrical energy to mechanical energy. They have an internal mechanism that changes the direction of current flow in the motor. There are two common types of DC motors.

a. Brushed

They are used when one is looking to save on cost and where the system application is simple and basic. Usually, the brushed motors are 75%-80% effective and are divided into four.

• Series wound

The field winding is connected in a series with the rotor winding. The speed varies, and it develops a large amount of starting torque. Speed control is usually poor because as the torque increases, the speed falls. These types are commonly used in automotive, lifts, etc

• Shunt

The field winding is joined in a parallel way to the rotor winding. The speed regulation is proper as torque increases without reducing the speed by increasing the motor current. They are ideal for use in equipment like vacuum cleaners.

• Compound wound

It is a combination of the series and shunt motors. Series has better starting torque while shunt is suitable for regulating speed.

• Permanent magnet.

It uses a magnet hence the name. The ability to start torque is excellent, and the regulation of speed is quite good. It requires low torque and precise control to run. They apply to robotics.

b. Brushless

They don’t contain brushes as the name suggests; hence they are mechanically simpler and use the DC. The motor usually has permanent magnets, four or more around the rotor. The rotor and stator turn at the same frequency. Brushless motors are 85%-90% efficient.

Conclusion

There is a variety of motors in the market, making it efficient for anyone wanting to buy one. Make sure you know your system application, for you to choose the most suitable motor.

A periodic table is a useful tool in Chemistry. It is used by students as well as scientists to predict the types of chemical reactions that a specific element can participate in. It also provides detailed information on different types of elements in chemistry. Different institutions have their versions of the periodic table. However, the basic components remain the same. On this write-up, we discuss VulcanChem’s version of the periodic table of elements.

VulcanChem’s periodic table

VulcanChem is one of the world’s leading manufacturer and provider of specialty chemicals. The products manufactured by the institutions are of high-quality. The products include building blocks, natural compounds used in the lab for scientific purposes, and reference compounds, among others. The company is located in California, USA, but has branches in other regions in the US, Europe, and Asia.

VulcanChem recently unleashed its molarity and molar weight calculators as well as its periodic table. Below are some properties of VulcanChem’s periodic table;

• Order- VulcanChem’s periodic table is unlike others in the market. Instead of arranging elements in informational cells in increasing atomic number order, the table consists of 5 columns and as many rows as the number of elements in existence.
• The elements on this periodic table are organized in alphabetical order. For instance, the first element is Actinium, and the last is Zirconium.
• The table’s first column consists of the names, in alphabetical order. The second one displays the symbols of each element, while the third consists of the atomic number of the element. The fourth column displays the relative atomic mass of the elements, and the third one has a reference link to a wiki web page with more information on the elements.

Advantages of VulcanChem’s Periodic table

One of the main benefits of this periodic table is the fact that it is very simple. The fact that it is a simple means that it is easy to read and understand. Unlike other periodic tables of elements established by other organizations, you do not have to do any work to understand the table.

The periodic table also organizes the elements in alphabetical order according to their name. This is not a common element in other periodic tables.

Definition of important terms used on the periodic table

• Element- An element is a component of a whole. Elements are found in all of the four substances discussed in Chemistry (air, water, fire, and earth). It can also be defined as a substance whose atoms all have the same amount of protons.
• Chemical symbol- A chemical symbol is an abbreviation used in chemistry for each element. It consists of a single letter or two at most. The symbol can either be an abbreviation of the English or Latin name of the element.
• Atomic number- An atomic number denotes the protons number in the nucleus of an element. It can also be defined as the number of electrons surrounding the nucleus of an element’s atom.
• Relative atomic mass- this is the mass of an atom in a specific chemical element.

Conclusion

A periodic table is used to solve problems in chemistry. Periodic tables are available online and in print form as well. However, different sources provide different types of tables. Regardless, the basics like the element names, symbols, atomic mass, and number remain the same on each one.

Metal finishing refers to the final phase of the metal fabrication process; this phase involves the use of a metal finishing machine in finessing the surface of the metal. The purpose of od metal finishing is to give the metal a smooth and well-shaped exterior. Some of the materials used in achieving this procedure include plating, loose abrasives, and tumbling media.

Various machines are adopted in metal finishing, and these machines vary in efficiency and capability. Often, the effectiveness of the machine is mostly dependent on the calibration of the machine. This article highlights some of the essential finishing machines as well as the unique qualities of each machine.

Barrel finishing machine

This type of finishing machine is so named because they use barrels to good effect during the finishing process. The machine usually possesses an 8-sided drum that rotates continuously; these drums allow metals to be rounded or surface treated. Abrasives, lubricating agents, and tumbler media are also injected into the barrel drum to generate the necessary amount of friction for surface finishing. Barrel finishing employs two processes in its operations; they are dry tumblers and wet tumblers. Each tumbler type has its unique application and capabilities; dry tumblers are useful in all the phases of the finishing operation while wet tumblers are more suitable for the removal of excess stock.

Vibratory finishing machine

This type of finishing machine employs the use of high-frequency vibrations in creating the desired surface on the exterior of the metal. The machine encloses the metal in intense frequency motion that could go as high as 1800 vibrations per second. The machine is especially suited to applying smooth surface finish to metals with deep vanities. The polish rate of this machine is topnotch, and it is capable of providing finishes to a variety of products in real-time.

Sandblasting

Sandblasting is quite popular for metal finishing due to its capability to clean and smoothen the metal at once. The machine does the cleaning and finishing by injecting abrasion agents like sand particles or metal pellets into the setup at a very rapid speed. The level of finishing is dependent on the speed of the abrasion particle, as well as the angle of the fire set up and the duration of the entire cleaning phase.

Plating machine

This type of finishing machine works by placing a layer of plating over the material’s surface. In most cases, the plating material possesses a desirable quality that the main material doesn’t have; some of such attributes include resistance to corrosion, magnetism, and attractive surface.

Hot blackening equipment

This type of metal finishing involves the coating of the surface of the material with black oxide for improved appearance as well as resistance to abrasion.

Final thought

Metal finishing is an essential phase of metal processing in the manufacturing industry, and its importance is because it allows manufacturers like Rapiddone to give metals an improved appearance. There are several ways in which metal finishing can be done, and each process has it’s uniqueness, as highlighted in this article.

The brewing industry is a multi-billion dollar industry. The sector incorporates both brewing companies, suppliers, and manufacturers of brewing equipment like cnbeerbrewingequip.com. The industry has been subject to a lot of changes over the years, especially in the areas of manufacturing. Traditionally, individuals practiced in-house brewing using cloths, however currently commercial and mass production of beer has led to the establishment of large breweries.

Some must-have equipment in a brewery is mashing, boiling, cooling, lautering, and fermenting equipment. Fermenting, in brewing, is the process through which sugars gets broken down into alcohol and carbon dioxide in the presence of yeast and a catalyst of the reaction. The type yeast used in the fermentation of beer determines the type of beer that is made.

Types of Fermentation in Beer Making

There are three main types of fermentation in brewing. To understand these modes of fermentation, you first need to understand the two main types of yeast.

• Ale yeast– this is a yeast that rises to the top of the fermentation tub or tank. It works best at warm temperatures between fifty-nine and seventy-seven degrees Fahrenheit.
• Lager Yeast– this is a type of yeast that sinks to the bottom of the fermentation tub. It works best at cold temperatures of between forty-one and fifty degreed Fahrenheit.

• Top Fermentation

This type is fermentation, uses ale type of yeast. In this process, the yeast is mixed with the beer, but after swirling throughout the beer, it settles at the top of the drink. Top fermentation is a style of fermentation where the yeast has a higher tolerance to the alcohol and the ferments at a higher temperature. Beers produced through top fermentation include brown, pale, and India pale Ale, Belgian, wheat, and Wheat Beer.

• Bottom Fermentation

The type of yeast that is used in this lager yeast as it sinks to the bottom hence the name bottom fermentation. Compared to its counterpart above, bottom fermentation is slower, and it happens at colder temperatures. This is because it has a lower tolerance for alcohol at high temperatures. Examples of beers that are a product of bottom fermentation include pale and dark lagers, pilsner and German-style bocks.

• Spontaneous fermentation

Spontaneous fermentation happens when the beer is exposed to both wild bacteria and yeast that both act as catalysts for the fermentation process. Belgium brewers were the first in the world to practice this type of fermentation. However, not too long after, other countries in the globe followed suit as it is the best method for making sour and funky-tasting beers. Examples of beers made in this process are Belgian gueuze, fruit lambic, and American sour beer.

Take Away

The process of making beer is an art, as well as a science. It is a pretty precise process that starts with the mashing of grains, which are, in this case, referred to as malt. The next steps are also exact, regardless of the manufacturers and the equipment in use. The difference lies in the areas of raw materials as they affect the flavors of the final product. As mentioned above, the type of yeast used also affects the kind of end product achieved.
