EPDM rubber is commonly used in the automotive industry to make several parts of vehicles including the seals of doors, the trunk, the hood, and the windows. It is also used for other purposes such as temperature controlling because of its insulating properties. Practical uses of EPDM rubber include cold rooms, radiators, garden appliances and electrical insulators, tubes and hoses, washers, solar panels, speakers, and headphones.
EPDM rubber can either be conductive or non-conductive which is why plasma treatment is needed to activate it and to achieve a strong bond between the rubber and the adhesive during the flocking process. It is also needed to wet the rubber in the slip coating stage to obtain the desired properties for adhesion. Plasma treatment is used as a replacement of chemical treatments as chemicals are generally dangerous, low yielding, and high in cost. Read more
Metal: Silver and gold may seem to have taken the throne but when it comes to building a strong automobile industry, it is base metals that take the lead. These have proven to be the key to success in terms of constructing durable structures and lasting vehicles. Read on to find out why metal is becoming increasingly popular in the automobile industry.
Characteristics of Metals
Can form alloys
Enables and speeds up various chemical reactions
Adds attributes to plastics such as flame resistance, decreased degradation rate etc
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
It is a well known fact that the environmental conditions of outer space are completely different from that of our planet. This is why durable materials such as steel are used to construct all tools and machinery that are used in outer space.
From space exploratory probes to the tiniest component of a space station, you will find steel everywhere. The reason behind this is that steel is capable of enduring high pressure and temperature and is least susceptible to corrosion as compared to other materials. It is thus, due to the utilization of steel and other metals, that space travel has become possible for humankind.
The Utilization of Steel in the Aerospace Industry
There are various components that are made out of steel in the aerospace industry. Steel is the choice of manufacturers in this regard since it is capable of withstanding very high temperatures and pressure changes which will melt other metals.
The following gives you a precise idea about the uses of steel in the aerospace industry.
Steel is used to create components such as jet engines which provide power to rockets and spacecrafts.
Given the durability of this metal, steel is also used to construct airframes.
Numerous alloys can be made with steel that enhance its properties.
The fuel tanks of space rockets are made out of steel. This is so because it does not react chemically with the fuel stored in the tanks.
The most crucial component that plays a pivotal role in maintaining the lifespan of the space rocket and also, the lives of the crew; is the heat shield. Made out of solid steel, this heat shield is responsible for tackling the aggressive thermal and pressure changes that the rocket experiences while traversing different layers of the atmosphere.
With so many uses, steel is the best material for vehicular construction in the aerospace industry. See the wikipedia article for more information regarding aerospace: https://en.wikipedia.org/wiki/Aerospace
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:
Freedom to create innovative designs
Flexibility in the integration of components
The Various Kinds of Plastic Used in the Automobile Industry
To work with materials and unleash their true potential, almost every industry needs to activate their surface to make them more reactive. The increase in the material’s reactivity makes it easier to work with and allows it to be used more effectively. Plasma is the fourth state of matter and is used in almost all industries as plasma technology is one of the most economical methods of surface treatment.
How does plasma activate surfaces?
Plasma state is achieved when additional energy is added to gaseous ions. When plasma comes into contact with the surfaces of polymers, it alters the surface by attaching functional or polar groups to it. The addition of polar or functional groups makes the materials reactive as these groups easily combine and react with other chemical groups. Once the properties of the material are altered, they can be used for a variety of different purposes.
The activation process primarily uses oxygen as a catalyst; however, some materials can react with plasma in open air, without the need of providing additional oxygen for the reaction.
What are the common types of plasma driven surface treatments?
Plasma surface treatments can be used for the following industrial treatments of materials:
Plasma Driven Surface Activation: Plasma treatments used to activate surfaces
Plasma Cleaning: Plasma is used to clean and prepare surfaces for various manufacturing processes
Plasma Bonding: Plasma is used to lower the energy needed to bond two materials together.
Plasma Surface Modifications: Plasma treatments can be used to generate new properties of materials by activation, conditioning, and functionalization.
Plasma Ashing: Plasma ashing is the removal of carbon from products during manufacturing or cleaning processes.
Reactive Ion Etching: In this process, plasma treatments etch the surfaces which have already been treated.
Plasma Functionalization: This process improves the functions of materials, especially adhesiveness, bonding, and printing.
What makes plasma ideal for surface treatment?
There are several factors that make plasma ideal for surface treatments. For one, it works on a wide range of materials which means that it can be used on multiple materials for multiple purposes. It also works uniformly on all surfaces and efficiently gives high quality results.
Apart from that, it is cheaper to use, store and maintain and has a fast treatment time, so plasma driven surface treatments are useful in the sense that they work well, and save both time and money.
