Calibrating your measurement microphone

Measurement microphones are, of course, designed to take measurements with scientific accuracy. In the same way that you wouldn’t use a microscope without first calibrating it, the same applies to the microphone equipment you’re using too.

What is calibration?

Simply put, calibration is the fine tuning to the set up of your equipment to maximise performance and accuracy of output. Just as Formula One engineers will calibrate their tyre pressures for optimal grip and durability, by calibrating your microphones and equipment, you can ensure consistent performance and measurements.

Adhesive Bonding – Techniques and Considerations

Plasma treatment nozzle

A technical synopsis of different methods of adhesive joining

Adhesives are considered as one of the most reliable options for joining two substrates together. Unlike other methods of bonding, adhesives keep the geometry and properties of the materials intact. The technique has considerably matured over the years and every industry relies on adhesive bonding to produce high quality products.

Techniques

Most substrates like metals and polymers are not wettable by adhesives and require some pre-adhesion treatment. There are a number of surface preparation techniques for making materials suitable for adhesions. Some of the commercially used techniques are: Read more

The Uses of Silicone in the Medical Industry

The Uses of Silicone in the Medical Industry

What Are Silicones?

These are polymers that consist of any inert and synthetic compounds made up of repetitive units of siloxane. Siloxane is a functional group consisting of two silicone atoms and an oxygen atom most frequently combined with hydrogen and/or carbon.

Why are Silicones used in the Healthcare System?

ipadA fairly large amount of history is attributed to the use of silicones in the medical industry. This is so because these substances are highly biocompatible and have increased resilience to various environmental as well as bodily factors. Silicones also display resistance to conventional sterilization methods because of being almost completely inert. All these properties make silicones a popular choice for the manufacturing of a range of reusable as well as disposable medical devices. Read more

The Increased Usage of Plastics in the Medical Industry

Stadium Plastic

From the earliest times of Mesoamericans to the modern times, the use of plastic has been employed to carry out the construction of various items all over the world. It has evolved tremendously to suit the requirements of the ever increasing demands of the human race. The use of plastic is extensively based on its durability and reliability amongst other qualities. Of all the construction materials available, plastic is the only substance which is used in a variety of forms.

Polymers have been of pivotal importance to humankind ever since 1600 B.C. With the invention of vulcanized rubber in the year 1839 and the discovery of polystyrene (PS) by an apothecary of German origin in the same year, there has been no looking back at the widespread utility of plastics around the world. Before commencing onto the advantages of using plastics in the world of Science and Medicine, you should know about the various kinds of plastic being utilized in this field Read more

How Plastics Have Shaped the Automobile Industry

Normally we only discuss the surface treatment of metal objects on this blog, but sometimes we also find the need to show how other technologies correlate to the one we are using.

Plastic is the most high performance substance used in the automobile industry today. Not only is it very light, but it is also as cost efficient as it is light and does not tax the engine. Estimates suggest that you can reduce your fuel consumption by 5-7% if you reduce the weight of your vehicle by 10%. Some of the other features that make this material appealing for automobile manufacturers are:

  • Recyclability
  • Minimal corrosion
  • Freedom to create innovative designs
  • Flexibility in the integration of components
  • Economical
  • Safe

Fundamentals of surface activation using plasma flame technique

Use of flame for increasing the surface tension of a substrate and making it suitable for adhesion, printing and painting is probably one of the oldest methods of the surface treatment used in polymer, automotive and aircraft industry. Although with the advancement in technology other methods of surface treatment like corona treatment have emerged, most manufacturers still prefer flame treatment over other techniques.

What is Flame Treatment?

Plasma flamePlasma flame is generated by simply combusting a fuel (composed of long hydrocarbon chains) under controlled temperature and pressure conditions. The flame is used to modify the surface tension of the substrate without changing its composition and properties. Plasma flame generation is an adiabatic process in which the temperature is set to 1816°C. Along with improving the surface tension of a material, flame treatment is also used for improving the quality and reliability of polyolefin. Plasma flame oxidizes the surface of the material, forming a 10nm thick oxygen film on the surface of the substrate, thus turning it into a hydrophilic material. This is the reason that plasma flame treated substances have better wettability than corona treated substrates. Another factor which makes plasma flame a more reliable option for surface treatment than corona is the composition of plasma flame.  Plasma flame is composed of a heterogeneous mixture of different functional groups which modify the chemical properties of the material being treated.
