What is plasma and how it is produced?

A plasma may be produced in the laboratory by heating a gas to an extremely high temperature, which causes such vigorous collisions between its atoms and molecules that electrons are ripped free, yielding the requisite electrons and ions. A similar process occurs inside stars.

What is plasma treatment for surface modification?

Plasma treatment is a surface modification technique that readily primes any surface for better acceptance of secondary manufacturing applications. Plasma is a reactive treatment process where positive and negative ions, electrons, and radicals react and collide as long as an electric potential difference exists.

Why is plasma treatment used for plastics?

Using plasma treatment, it is possible to prepare and clean plastic and composite materials, and make them ready for finishing. The increase in surface energy from plasma treatment improves the measure of adhesion and assures the effectiveness of an applied coating. The results of this study demonstrate that heat-sensitive substrates like plastics and composites can be prepared with plasma treatment and successfully coated with UV-cured powder without degrading or deforming the integrity of the substrate.#N#UV-curable powder is 100% solid material, solvent- and water-free, durable, and has a high measure of adhesion when applied to a properly prepared and pretreated -substrate.

What is plasma treatment?

Plasma treatment convert s a low-energy surface to a high-energy surface, and makes it more hydrophilic and wettable. Adhesion of a coating has a direct correlation to wettability, the more wettable a surface the better the adhesion. Plasma has six components; electrons, ions, free radicals, byproducts, photons and neutrals.

What is plasma in science?

Plasma is often referred to as the fourth state of matter; solid, liquid and gas being the primary three (Figure 3). Thermal energy, its addition or removal, is the intervening input that changes the nature of matter. Plasma is a gas that has the capacity to conduct electricity.

What is the first measurable test for adhesion?

Testing adhesion is the first measurable test when evaluating performance of a coating material, regardless of the type substrate - metal, wood, plastic, composite, paper, glass or engineered materials. In lay terms, this can be expressed as “does it stick to the substrate,” and if so, “what is the measure of adhesion?” The measurement of adhesion applies to all forms of coatings - liquids, powder coatings, varnishes and inks. A coating’s curing system or mechanism is independent of the measure of adhesion. Regardless of the type of curing - ambient air, thermal energy or radiation energy (UV or electron beam (EB)) - the coating has to “stick” to the substrate. A coating that is applied and cured correctly does not guarantee the coating will adhere to the substrate. Proper preparation of the substrate prior to coating is the most important and determinate factor in achieving the desired measure of adhesion for any coating on any substrate.

What is the wettability of a material?

Wettability refers to the interaction between a fluid and solid phase, and measures the tendency of a material to spread and flow on a solid surface.

What are the benefits of UV coating?

UV-cured powder coatings offer many operational benefits: lower energy consumption, the application system has a smaller plant footprint, and increased productivity. In addition to these operational benefits, UV-cu red powder coatings also have health, safety and regulatory benefits.

What is the ASTM D3359 method?

ASTM D3359 1 is the standard and accepted method to measure and classify adhesion of a coating material to a substrate. The coating is cross-cut scribed at specified spacing using a knife or a cutting device (Figure 1). A pressure-sensitive tape is applied over the scribed area and then pulled sharply off the substrate. Adhesion is classified by the percentage of paint removed by the tape from the substrate (Figure 2). 5B is the optimum classification, 4B is often acceptable, anything less is a failure and not acceptable. This classification method is used throughout this study.

What is plasma treatment?

For many applications, plasma treatments are utilized to increase the surface energy of the material. Surface energy is the sum of all intermolecular forces on a material, the degree of attraction or repulsion force a material surface exerts on another material.

What is plasma used for?

What is plasma in chemistry?

Plasma is a state of matter, like a solid, liquid or gas, created by combining energy and gas, which causes ionization. Injection and blow molders can control the collective plasma properties (i.e.-ions, electrons and reactive species) to clean, activate, chemically graft and deposit a wide range of chemistries onto a material.

Is synthetic polymer hydrophobic?

However, untreated synthetic polymers are highly hydrophobic and provide inadequate binding sites for cells to anchor effectively to their surfaces. To improve biomolecule attachment, survivability and proliferation, the material must be surface modified using plasma to become more hydrophilic.

In plasma gasification, feedstock (trash) is introduced into a vessel of extremely high heat (~2,000 deg F) capable of breaking all organic chemical bond and reducing all trash including plastic, paper, glass, yard waste, food, filth, etc. to basic elements. The heat also melts metals, which are recovered.

On the other hand, there are multiple efforts to increase plastic recycling through the following: 1 Inventing new chemistry of plastics to become recyclable; 2 Reuse packages and products made of plastics; and 3 Developing new biodegradable plastic formulas to provide the required performance.

What is syngas used for?

Depending on the regional economics, syngas can be used for electrical power, methanol or liquid fuels such as jet fuel, diesel, synthetic natural gas generation and others. Plasma gasification is not to be confused with incineration, which is the burning of waste-emitting greenhouse gases and creating ash.

As it stands today, our municipalities are now all scrambling ...

When was the first landfill opened?

The first municipal sanitary landfill to open was in 1937 in Fresno, CA. It was considered innovative at the time with new techniques of trenching, compacting and covering of waste with soil. Since then because of the considerable amount of open and cheap land we have accepted the practice of landfills in the U.S., and now there are more than 10,000 municipal landfills that have reached maximum capacity, leaving 3,091 active landfills according to the EPA. Long gone are the days where every town had its own dumpsite. According to the EPA, there are seven states that will be running out of landfill space in the next five years. With the closure of the Fresh Kills landfill, New York City is sending its trash to Ohio, Pennsylvania, West Virginia and elsewhere. Large city centers are especially challenged and driving waste further and further to reach landfills creating higher costs and increased carbon emissions.
