Coolant is a complex of surfactants with multicomponent additives, including antibacterial and anticorrosive ones.
By classification Coolants can be water-miscible and non-water-miscible. Regardless of the type of coolant, the spent working solution, depending on contamination, needs to be changed in time.

When coolant needs to be changed in machines:

• Mechanical pollution and bottom sediments (ingress of chips, scale, rusty fragments from dirty parts, foreign liquids and oils).< /li>

The consequences of such contamination are the appearance of corrosion and / or sticky deposits on equipment and parts.

• Bacterial damage to the working solution (occurs when the permissible concentration of the working solution is underestimated, during long-term downtime of the equipment, when using water from a well or a well).

In case of bacterial damage, the working solution changes its color to dark gray, and a sharp unpleasant odor appears. Service personnel can often experience skin irritation.

In case of the above problems, it is urgent to replace the working solution in the machine.

How to change coolant correctly

The coolant replacement process involves several steps:

1. Draining the used coolant: completely remove the old coolant from the tank, clean the bottom sediments.
2. Cleaning the tank: thoroughly wipe the internal surfaces with a dry cloth.
3. System flushing: prepare a 3% solution by mixing 1 part of Biol Eco with 30 parts of water. Pour it into the system and let it circulate for 2-6 hours.
4. Drain the flushing liquid: after circulation, drain the solution, wipe the container dry again.
5. Filling in new coolant: prepare a fresh solution (for water-mixing coolants) or use ready-to-use fluid.

Recommendations for changing and preparing the working coolant solution

1. Use special containers: the solution should be prepared in a separate, dedicated container.
2. Designate a person to be in charge: one person should supervise the replacement and preparation of the solution.
3. Use filtration equipment: this prevents chips and other contaminants from entering the system.

The Changing the coolant: How to correctly renew the coolant in machine tools. message appeared first on Novohim.

Over the past 20 years, a large number of new equipment for glass, ceramics and stone processing has appeared on the Ukrainian market. Very expensive CNC machines with vertical and horizontal feed. Such equipment performs immediately up to four or more operations with the obligatory use of coolant during operation. In addition, we know that glass, like stone, is a very hard but brittle material, and for their high-quality processing, the first requirement is the use of cutting fluids.

Hence, the conclusion is that the use of low-quality cutting fluids or the complete rejection of the use of coolants in the processing of stone or glass can lead to premature wear and tear of expensive equipment and tools, as well as loss of processing quality and damage to parts.

Types and characteristics of coolant for processing glass, stone and ceramics.

• Semi-synthetic coolants based on mineral oil

When studying the coolant market, we saw that manufacturers most often offer them. However, many glass and stone workers have complained about oily streaks on the treated surface. In addition, quick filling of the working solution, especially in the summer.

• Synthetic coolants for glass, marble and granite.

Taking into account all the above disadvantages of other manufacturers, the technologists of the Ukrainian enterprise JSC KHIMPROM developed a unique Defender-Stone synthetic cutting fluid for cutting glass and stone.

Top 8 Coolant Benefits for Glass and Stone Defender -Stone:

1. The use of this coolant reduces the friction temperature in the grinding and polishing area by more than 50%
2. Double the surface finish
3. Excludes the possibility of part defects during processing
4. Ensures the safety of equipment and tools.
5. Does not leave greasy stains on the surface, easily washed off with plain water, no detergents
6. Perfectly removes glass and abrasive residue from the surface of the machine, protecting it from rust.
7. Thanks to German antibacterial additives, it does not clog up to 24 months, protects the working solution from the formation of fungi.It does not contain harmful substances , which are used by many manufacturers, namely; sodium nitrite, chlorine, boric acid, formalin, diethanolamine, which makes it safe for service personnel.

The price of coolant for glass and stone processing from Novokhim fully justifies its quality and expediency of use.
It is diluted in water with any hardness, for 19 liters of water 1 liter of concentrate.

There are certain rules for working with coolant. And workers who are involved in the process of machining metal simply you need to know them. Knowing the 10 rules for working with coolant will make your work easier and save the material assets of the enterprise as a whole.

Coolant rules:

1. Equipment, coolant preparation and supply systems, tanks and other containers must be clean!!!
2. To prepare mortar Coolant use tap water with a hardness of 2 to 7 mg-eq / l. Water from wells and springs requires water treatment.
3. When cooking solution pre-mixed concentrate must be poured into water, not vice versa.
4. Use filtration equipment to remove oil, chips and other contaminants from the coolant. Or remove them with a skimmer, slotted spoon or scoop. Mechanically remove settled deposits in the storage tank
5. Before coolant change it is necessary to drain the old one in full, clean the tank of the machine from oil, dirt and other deposits. Then wipe dry with a rag inside the tank. Then fill in the flushing liquid Biol-Eco 3% (1 part concentrate to 33 parts water) and let it work for 2 hours. After drain.
6. When cooking coolant solution clearly follow the manufacturer’s recommendations for the concentration of the working fluid. Especially in the summer, when the water from the working solution of ZOR is more actively evaporated.
7. For validation preparation of working solution use refractometer (ask the coolant manufacturer).
8. Coolant concentration measurements spend regularly. This will help determine the dynamics of the behavior of the working fluid and troubleshoot in time.
9. Refilling the machines should be done only with a coolant solution, not with water!!!Prepare the working solution in a separate container specially designed for this purpose.
10. To control fix a specific person with a state of coolant. Log coolant condition indicators.

It is a common case, especially in winter time, when a customer has opened a drum of oil-containing coolant and it has separated. What is it, low-quality coolant? Certainly, the coolant is of high quality, and the stratification, which is present in the barrel with the lubricating-cooling liquid, is a natural process of emulsification, which can start in case of sharp temperature change. To eliminate stratification it is necessary to put the coolant barrel in a warm place, let it warm up and mix it thoroughly (preferably with an industrial mixer).

In summer, when high temperatures and humidity favour the active development of harmful microflora, especially if equipment and machines are not kept clean. Contamination and metal swarf residues create a favourable environment for bacteria, resulting in faster deterioration of coolant, unpleasant odours and poor working conditions. Regular cleaning of the equipment is the key to stable and safe summer work.

Follow these guidelines in your business. And you must will definitely see that working with cutting fluid has reached a completely new, higher level.

Sticking, corrosion of parts and tools, skin rashes and other troubles are possible only from the lack of cleanliness of containers and equipment. As well as improper preparation of the working solution and concentration of the cutting fluid.

If you have any questions about working with coolant, please contact the managers or technical specialists of the sales department at the numbers indicated on the site.

IMPORTANT! These recommendations apply only to cutting fluids produced by JSC Khimprom. Since we are 100% sure of high quality, environmental friendliness and the absence of substances toxic to humans in the composition of these products.
