Suitable and Favorable Air Cement Gun Makes Everything Easier!

    Air Cement Gun is the machine which uses compressed air to cast a stream of cement and concrete onto the surfaces of construction with high velocity. It is also know as “gunite” and “shotcrete”. As the matter of fact, there are two different basic processes for the pressure gun applications, including dry and wet mix applications. Cement gun techniques can allow for the rapid application of large quantities of structural/non-structural cement on vertical and horizontal surfaces. Because of the advantages of project the mix with high speed onto surfaces, many decorative mortar applications are used with the cement gun.

     In the early 1900s, Carl Akeley developed the air cement gun as the method of applying plaster slurry to the taxidermy models. In general, the process is partially flexible and appropriate to apply with simple cement, send mixtures, and structural concrete aggregates. It is also used in the construction projects which range in size from large commercial high rise buildings to swimming pools (redecorating projects).  When you consider buying the gun, you should notice there are various types of gun.  The suitable and favorable air cement gun could make your decorative procedures become a quick and easy affair.

 

You Never Know That >> What is “magnet” or “NdFeb magnet”!?

Everyone knows what “magnet” is, but he/she must do not know what the magnet is made by.  Actually, Magnet is made by lodestone.  When the magnetic qualities of lodestone are passed into the magnetic substance, it will be the permanent and long-lasting magnet.  We can also define that the magnet is the material or the object that can produce the magnetic field which is invisible but is the most remarkable property of the magnet.  In addition, the most common type of rare-earth magnets is “Neodymium-iron-boron” magnet. 

Neodymium-iron-boron magnet is generally known as “NdFeb magnet”, “NIB magnet”, “Neo magnet”.  It is mainly made of many substances, including alloy of neodymium, iron, and boron.  This kind of magnet can not only replace other types of magnet in many applications, but also provide the highest available. 

The greater strength NdFeb magnet can supply with the given application in the modern products, such as hard disk drive, motors in cordless tools, etc. Therefore, NdFeb magnet is the very significant material in the industry and technology.

 

Advantages of Fresnel Lens

Fresnel lens present in the overhead projector focuses the beam of light produced by the projection lamp. It projects itself to the optics in head assembly. Actually, a thin piece of plastic magnifying lens present in the overhead projection screen is known as th
e Fresnel lens, which is completely flat on one side and ridged on other. In most of the overhead projection screen, two pieces of thin acrylic lens are placed together, known as dual element Fresnel lens.  But in fact, these lenses were used to focus the light beam on the lighthouse lamps.

The plastic lenses are used wherever a concentrated stream of light is required. Therefore, these lenses are used in the overhead projector where a concentrated light beam is used to project an image on the wall or screen. The function of Fresnel lens can be improved by the usage of spattering technology which is suited to the requirement of micro mini lens.  It is indeed a delight to know that the performance of the lens can be calculated on the basis of coating degree and thus can be managed and controlled according to requirement.

Another advantage of the Fresnel lens is that it can easily reduce the amount of material used in building the lens in comparison to conventional spherical lens by dividing it into a set of concentric sections called Fresnel zones. Though a Fresnel lens appears to be a single glass piece, it actually is composed of numerous smaller pieces of glass. Fresnel lenses with a single piece are used in automobile headlamp, brake, parking and turn signal lenses, to name a few.  

Introduce the Metal Core PCB

The printed circuit bard is widely used to connect the electric components with the pathways of the conductive and traces of the signal.  The flexibility has made the PCB become a must have tool for especially small electric equipment.  The PCB comprises of highly advanced chips as well as other essential electronic applications that are placed on a slim plate for functioning. 

There are also many types of PCB, and one of the most commonly used types is called metal printed circuit board.  It is built with a base metal core used to disperse heat through the components of the board, lowering the core temperature of high heat applications.  The metal core printed circuit board works when the heat transfers up to eight or nine times, then laminates scatter and eliminate heat, keeping heat generating components cooler which results in increased performance and the life of the applications.  Most of the time, the metal core PCB is used when conventional cooling techniques are insufficient for chilling down the entire system.  They are normally multi layered boards. They can also be built on a flex board or rigid flex board for tight space areas or custom sized applications, such as mobile phones.

Others like LED, which is also quite common application, can also feature with aluminum PCB or a mixture of special alloys.  The LED applications generate large amounts of heat by using the metal core dielectric polymer layer with a high thermal conductivity.  The application has a lower thermal resistance, and it makes the PCB perfect enough for various LED usages like power converters, electric motor control or photovoltaic.
