Understanding Plastic Materials
Plastic materials are a type of synthetic materials used in many different applications. They are extremely versatile, durable, and cost-effective, making them very popular in the manufacturing industry.
When it comes to understanding plastic materials, one must first consider the different types of plastics available. These include thermoplastics and thermosets as well as elastomers and composites.
Thermoplastics can be remolded with heat while thermosets remain rigid even when exposed to high temperatures. Elastomers are flexible polymers that are tough and resistant to wear, while composites combine several materials for added strength or improved properties such as thermal conductivity or stiffness.
In addition to their physical characteristics, plastics also come in a variety of colors, textures and shapes. This allows them to be used for many different purposes, including cosmetic packaging, automotive parts, medical equipment and other consumer products.
Understanding the various types of plastics and their properties is necessary for successful product design and manufacturing.
It’s also important to understand how plastic materials can be processed to achieve desired outcomes. Depending on the application, plastics may need to be heated or cooled, twisted or stretched, cut or molded into shape. Different techniques are used depending on the type of material being processed as well as its intended use. For example, injection molding is often used to produce intricate parts while extrusion techniques can create longer pieces of plastic with uniform cross-sections.
Finally, understanding the environmental impact of plastic materials is essential for companies looking to produce sustainable products. Plastics are derived from petroleum sources and their production can lead to pollution and other forms of resource depletion. Recycling plastic materials and using biodegradable options when possible can help mitigate these issues.
Ultrasonic Cleaning Effectiveness Depends on the Kind of Plastic
Plastic Rigidity
The effectiveness of ultrasonic cleaning on plastics depends largely on the rigidity of the plastic and its ability to withstand the high-frequency sound pressure waves created by the transducer in a sonic cleaner. Plastic materials that have a high degree of structural strength, such as ABS (acrylonitrile butadiene styrene) or PET (polyethylene terephthalate), are much more resistant to ultrasound than softer and more flexible plastics, such as polyvinyl chloride (PVC).
As a result, it is highly recommended to use ultrasound only on rigid plastics with strong molecular bonds.
Plastic Porosity
Another factor that affects how well an ultrasonic cleaner can clean plastics is porosity. A plastic with a large number of tiny pores is more susceptible to ultrasonic cleaning than one without any. When exposed to high-pressure sound waves, these small pores can absorb and hold onto the detergents and cleaning solutions used in ultrasonic cleaning, making it easier for them to dissolve dirt, oil, and other contaminants. However, if the plastic is too porous or has too many crevices, it can also make it difficult for the cleaner to reach into all of its recesses.
Ultrasonic Cleaning Frequency
The frequency setting of an ultrasonic cleaner also plays an important role in how effectively it cleans plastics. Ultrasound frequencies range from 20KHz (kilohertz) up to 70KHz with higher frequencies being more suitable for plastics with a harder structure.
Lower frequencies are better suited for softer and more flexible plastics, as they will tend to create fewer cavitation bubbles, which can cause damage to the surface of the plastic.
Plastic Density
The density of plastic can also affect the effectiveness of an ultrasonic cleaner. Higher-density plastics have a greater ability to absorb the sound waves created by an ultrasonic device, resulting in deeper cleaning and more effective removal of dirt, oils, and other contaminants. On the other hand, lower-density plastics require longer exposure times to achieve adequate cleaning results.
Surface Hardness
The hardness of the plastic’s surface can also play a role in how effective an ultrasonic cleaner is. Soft and porous surfaces are more susceptible to cavitation bubbles created by ultrasound and therefore require gentler exposure times or lower frequencies for adequate cleaning. Harder surfaces such as ABS or PET can tolerate higher frequency settings and shorter exposure times, making them easier to clean with ultrasonic technology.
Degree of Contamination
The degree of contamination on a plastic surface can affect how well an ultrasonic cleaner works. Heavily soiled surfaces may require longer exposure times or higher frequency settings to ensure effective cleaning results. On the other hand, lightly contaminated surfaces may only need low frequencies and short exposure times for satisfactory results.
Plastic Composition
The composition of the plastic can also impact how well an ultrasonic cleaner works. Plastics that are composed of a mixture of different materials, such as ABS and PET, may require different frequencies or exposure times to achieve satisfactory results. Additionally, plastics that contain metal components may not be suitable for ultrasonic cleaning due to the risk of corrosion [1].
Things to Consider When Choosing Ultrasonic Cleaning for Plastics
Does the part float?
Ultrasonic cleaning is effective when the part being cleaned needs to be suspended in a cleaning solution. If the part floats, then it should not be put into an ultrasonic cleaner as this can cause parts to move around and interfere with the ultrasonic activity.
Is surface uniformity important?
If you are looking for an even clean across all surfaces of a part, then ultrasonic cleaning may be a better choice than other methods. This is because the cavitation created by ultrasonics helps remove dirt from hard-to-reach areas and gives a more consistent finish.
What type of plastic is it?
Different plastics require different types of cleaners. For example, some plastics may react negatively to certain acids used in cleaning solutions and so an appropriate cleaner should be used. It is important to consult product documentation or a knowledgeable professional before proceeding with the ultrasonic cleaning of plastics.
How heavily contaminated is your item?
Ultrasonic cleaning is most effective when a part is lightly contaminated. This means that if the dirt or debris on the part is particularly stubborn, then other methods such as manual scrubbing may be necessary.
What are your overall cost considerations?
Ultrasonic cleaning can be an expensive process due to the cost of equipment and supplies. However, it can help reduce costs in other areas such as labor and time spent manually cleaning items. Before making a decision, carefully consider both the initial outlay and long-term savings associated with ultrasonic cleaning.
Can your item handle the heat?
Ultrasonic cleaning produces heat due to the vibrations of the ultrasonic waves. This heat can cause some plastics to warp or deform so it is important to consider if your item can handle the extra heat before using an ultrasonic cleaner.
Is the chemistry safe for your material?
Some plastics, such as polypropylene, can be negatively affected by certain chemicals used in ultrasonic cleaning solutions. It is important to research the type of plastic you are cleaning and make sure that the solution you choose is safe for use on your item.
Does the shape of your part matter?
Ultrasonic cleaning works best when there is a consistent amount of surface area exposed. If parts are small or have an irregular shape, they may not receive enough exposure to the ultrasonic waves and therefore will not be cleaned as effectively [2].
What are the alternatives to ultrasonic cleaning?
Ultrasonic cleaning is the most efficient way to remove dirt and contaminants from hard surfaces, but other methods may be more suitable for certain materials or objects. Alternatives to ultrasonic cleaning include hand scrubbing with a brush or sponge and chemical cleaners, steam cleaning, vapor degreasing, and media blasting. Each of these methods offers advantages and disadvantages depending on the material being cleaned and the type of contamination present.
Hand scrubbing is relatively inexpensive but labor intensive, while chemical cleaners can be toxic if not used carefully. Steam cleaning is fast and effective but requires special equipment to generate high-pressure steam. Vapor degreasing uses solvents that evaporate quickly but needs to be done in a well-ventilated area. Media blasting is ideal for larger objects but can cause damage to fragile materials if not done correctly.
Each of these methods has its own benefits and drawbacks, so it is important to choose the right one for your particular needs. Ultrasonic cleaning is a reliable and effective option in many cases, but it may not be the best choice for every situation. Consider all available options before deciding which method will work best for your project.
