You can check whether there is solidification or iron filings fence net blocking in the water tank. Generally, the water tank will be designed with iron nets to block iron filings and prevent foreign bodies from sucking into the pump. Therefore, it is necessary to confirm that the height of the iron nets should not be higher than the water surface, and the oil slick should float on the water surface without being blocked, so that the effect of oil-water separation will come out. 
Again, you need to confirm that the cutting fluid has a "strong" resistance to the chute oil, and the effect will be good, and there must be no emulsification.
 
1. Cutting fluid can be divided into synthetic and non-synthetic, and its effect is different. Try to choose which cutting fluid has better oil/water drainage resistance. The cutting fluid with better oil/water drainage resistance has the best effect, and the cutting fluid with poor oil/water drainage resistance will be similar to the phenomenon of "emulsification". If so, your oil/water separation effect will be quite poor.

1mg= 0.001ppm

PPM is the concentration of parts per million, 1PPM = one part per million
1mg = 0.001ppm

Ultrasonic (Ultrasonic), audio f=1/T sound wave or vibration (Vibration), its frequency exceeds the range that human ears can hear (20Hz~12KHz).
Ultrasonic is widely used in many fields such as medicine (detection, treatment), industry (cleaning, welding, implantation), military (ranging), etc. due to its high-frequency characteristics.
So Ultrasonic is defined by the audio frequency that is so high that the average human ear can’t hear it.
Ultrasonic waves can be vibrated in air, liquid or solid.

Ozone, also known as super oxygen or active oxygen, is composed of three oxygen atoms. It is a non-toxic, colorless gas with a fresh smell of grass. It is also a powerful oxidant and bactericide second only to fluorine in nature. Its bactericidal power is longer than normal. The chlorine is 600 to 3000 times higher.
 

1. Power ultrasonic: applications include welding, crushing, cleaning, emulsification, etc., which only transmit power for functional output and do not accept feedback signals.
2. Detecting ultrasonic waves: Most of the ultrasonic waves used in this method are used for medical examinations, assisting in medical diagnosis and treatment, and the frequency is usually 2M~15MHz

Ultrasonic cleaning machine
For cleaning parts, it is usually best to use ultrasonic equipment for processing efficiency. Its principle is to use the ultrasonic vibrator to vibrate in the water to cause the molecular structure of the water to collide and peel off the residual foreign matter on the surface of the part to be cleaned to achieve cleanliness. The effect is that the parts that usually contain oil stains can be cleaned by applying hot water.

Ultrasonic welding machine
Can be used for welding (fixing, punching, implanting, cutting burrs, etc...)
General plastic (not cotton) materials can be used for the above purposes. Ultrasonic welding applications can eliminate the use of glue (strong adhesive) to stick in the past, making it more efficient, stable and fast...
 

Ozone O3, at room temperature, it is a colorless gas with a special smell. Ozone has a fishy smell. Inhaling a small amount is good for humans, and inhaling too much is harmful to human health! Ozone is widespread in nature, and its concentration varies under different conditions. It is not easy to be noticed.
The ozone layer in the atmosphere, which is now generally understood, is a natural barrier to block the sun's ultraviolet rays. It is produced by sunlight with a specific wavelength spectrum of light irradiating the air. After a thunderstorm, people will breathe a special fresh taste, which is actually the increase in the concentration of ozone in the air, which is easy to be noticed by people. The increase in ozone concentration is because lightning (high-voltage discharge) ionizes oxygen in the air to form ozone. The decomposition rate of ozone varies with heat, light, moisture, and PH value, and the decomposition rate is accelerated due to the action of metal oxides and other catalysts. When active bacteria encounter ozone, the lethal concentration of ozone will make it immediately lose its vitality. Don’t feel bad because it is called “ozone”. Ozone smells like in the forest, under a waterfall, or in a big place. The faint scent of grass can often be smelled after a thunderstorm. There are two types of ozone in the universe, one is "natural ozone" and the other is "environmental ozone."

Ozone is a widely used bactericide, which can kill bacterial propagules and spores, viruses, fungi, Staphylococcus aureus, etc., can destroy botulinum toxins and toxins and rickettsiae, etc., and also has a strong, in addition to mildew, fishy, smelly and other odors.
Ozone is a strong oxidant. The role of ozone in the air can not only deodorize, but also keep food fresh, and it will return to oxygen after oxidation without leaving residue, but it should be noted that it is strongly irritating. When the concentration is 0.005ppm, It will lead to dizziness or unsmooth breathing.

1. ABS and acrylic are best fused
2. PC, POM (plastic steel) are second
3. PP, PE again third
4. PET, PBT (meltable, but not easy to melt), note: if the fiber content of PBT is higher than 13%, the fusion will be powdery

Of course, we must understand that the strength of ultrasonic welding can never reach the strength of one-piece molding :

The result of welding ABS and ABS to each other is definitely stronger than the strength of welding ABS and PC to each other, because the melting points of two different materials will not be the same. Of course, the strength of welding cannot be the same, although we discuss ABS. Can these two materials be welded with PC? Our answer is that we can definitely weld, but is the strength after welding what we want? Not necessarily!

On the other hand, what if ABS melts with Nylon, PP and PE? If the ultrasonic HORN (upper mold) emits heat energy of 150 degrees in an instant, although the ABS material has been melted, the nylon, PVC, PP, and PE may only be softened. We continue to heat it to above 270 degrees. At this time, Nylon, PVC, PP and PE have reached the ultrasonic welding temperature, but the ABS material has been resolved into another molecular structure! Three conclusions can be drawn from the above discussion :

1. Plastic materials with the same melting point have the strongest welding strength.
2. The material melting point difference is too large, the welding strength is worse.
3. The higher the density of the plastic material (hardness), the higher the welding strength than the lower density (higher toughness).
