The cutting fluid stock solution can be stored for no deterioration after adding water to 1 1 and se

The above stem is to say that the cutting stock solution is sold with water after being purchased from the manufacturer.

Cutting fluid (coolant) is a kind of industrial fluid used in the process of metal cutting and grinding to cool and lubricate tools and workpieces. It overcomes the problems of traditional soap-based emulsion that it is easy to smell in summer, difficult to dilute in winter, and has poor anti-rust effect, and has no adverse effect on lathe paint, and is suitable for cutting and grinding of ferrous metals, which is the most advanced grinding product at present. The cutting fluid is better than the saponified oil, it has the characteristics of good cooling, cleaning, rust prevention, etc., and has the characteristics of non-toxic, tasteless, no erosion of the human body, no corrosion of equipment, and no pollution to the environment.

In fact, it is not a deterioration problem, the cutting fluid has a fungicide that will not deteriorate for 1 year, and after adding water, I am afraid that the appearance of the cutting fluid will change, such as delamination and side mixing, so it is not easy to sell.

If it's a fully synthetic product, it doesn't matter how you add water.

If it is an emulsion, it will already be mixed after adding water, although it will not deteriorate, unless you have a good relationship with the customer, this appearance is generally not acceptable. As for semi-synthetic products, it depends on the product system, and the appearance of 15-30% water with low oil content is still stable. If you add too much water-in-water, it will become oil-in-water, and you can't sell it once it's layered.

How long the cutting fluid is put in the working fluid should vary greatly from site to site.

Let's talk about it from three aspects:

First, look at the stability of the product itself.

Stability consists of 2 aspects, 1The stability of the system is that there will be no oil-water stratification, 2Antibacterial, the general cutting fluid contains fungicides, most of the fungicides will cause harm to the human body, high-end products will have biostable technology cutting fluid, and do not contain fungicides to use protobacteria to inhibit harmful bacteria.

Generally speaking, imported brands such as Basso, Castrol, Fox, and Quake have a normal working life of half a year to a year, and there are also good ones in China.

2. Special materials.

Copper alloys, magnesium alloys, cast iron, and cemented carbide have different characteristics that have an impact on the life of cutting fluids.

For copper alloys, if the cutting fluid still has active chlorine or no corrosion inhibitor, the cutting fluid will soon turn green, which will also cause copper corrosion.

Magnesium alloy machining will increase the magnesium ions of the cutting fluid, which are also hard water agents, which will cause the cutting fluid to produce insoluble metal soap, resulting in the deterioration of the cutting fluid.

Cast iron processing is very simple because of the high carbon content, carbon itself has lubricity, generally using dry processing, if the cutting fluid is used, a large number of iron powder, toner mixed into the cutting fluid, if the cutting fluid sedimentation is not good, iron powder, toner will hang or float in the cutting fluid, resulting in the cutting fluid smell.

Cobalt will be precipitated during cemented carbide machining, and if there is no corresponding additives, the cutting fluid will become more and more red, affecting the life.

3. Daily maintenance.

This is the main factor, and if the on-site operator throws cigarette butts and food scraps into the tank, no matter how good the liquid is, it is useless.

If the equipment leaks seriously, and the oil-water separator is not used, no cutting fluid can be used.

On the contrary, if the domestic cutting fluid has good maintenance (regular inspection, concentration, pH, bacterial count, filter floating oil, and add fungicide), it can also get a good trial life.

In the end, it is very one-sided with emotions to make a conclusion, 6000-7000 imported products do not need to be changed to ** merchants in 1 year, and 3000 domestic products are good for 6 months. You get what you pay for.

This depends on the quality of the cutting fluid, some cutting fluids are layered after a day of water, and some are layered after 1 year, and the water added is also related, generally with tap water, some water hardness is large, and some water, hardness is relatively small.

1. There are many possibilities, first of all, the problem of hydrolysis, it depends on whether there are substances that are easy to hydrolyze in your formula system, some substances will be slowly hydrolyzed after dilution, and some hydrolysates are insoluble in water.

2. The hardness of water, the hardness of water is not too high, and the turbidity is relatively slow, usually in 12-24h, the non-insoluble substances formed by calcium and magnesium ions and fatty acids in the water.

3. When the pH decreases, the cutting fluid exposed to the air will absorb the carbon dioxide in the air, and the bacteria will also cause the pH to decrease, so that the free fatty acids will not be neutralized and will be precipitated.

After the cutting fluid is mixed with water, it should be observed whether it has delamination and oil separation. There are many varieties of cutting fluids, but they all have three elements. 1. Hard water resistance, good stability, no delamination. 2. Anti-rust 3. Lubrication. Your sticker is too general, and the lubricity is generally related to the concentration.

Was it transparent in the beginning? Is it a fully synthetic cutting fluid?

If it is transparent and white and cloudy at the beginning, it is mixed with hydraulic oil and lubricating oil, which does not affect the use and does not need to be replaced.

You need to go into more detail.

What type of cutting fluid is used, what is the concentration of BRIX, what is the machining, what material, can help you be more accurate.

It is recommended to change the cutting fluid, you are this because of the unstable additives and poor quality, which generally does not happen.

1. Resistance to hard water. 2. The emulsified dose is insufficient. 3. Self-emulsifying esters are used.

It is unlikely that it will change color after a few days of non-use, and if it turns white after use, it is caused by the mixing of miscellaneous oil!

1. It is possible that the product is not resistant to hard water, 2PH drops, and emulsifier problems.

At present, there are few imported loading of cutting fluid, at most it is an imported formula, and it is awesome hula, shouting **** production everywhere, isn't it just a brand? . .

You can try adding some water softener.

The turbidity is caused by oil demulsification.

There must be an ingredient in oleic soap.

Cutting fluids are susceptible to microbial ingress.

Leave it out for a while to change color? Do they have a quality inspection report for their products? Or is there a mixture of microorganisms? Generally speaking, there are only two possibilities.

The resistance to hard water is not very good, and the life span is not good2

The replacement manufacturer product is unqualified.

Did you solve the problem? will change.
