How to do on site experiments on cutting fluid, and what are the general experimental methods used f

The most important thing to pay attention to after changing the oil for water-based cutting fluid is whether the oil groove is cleaned, otherwise it will be a second time.

Pollution will affect the quality of your cutting fluid, and the following points are for your reference

Bring a pH test strip (pH meter), a transparent paper cup, a concentration meter, a transparent PET bottle, an appropriate amount of fungicide, and a nitrite test paper.

a) For the first time, you can add an appropriate amount of deodorant (biocide) to ensure that the previous oil will not affect your cutting fluid.

b) To make a step of mixing water, take a small transparent paper cup and mix it 1:20 or 1:15 to show him.

c) Take the concentration meter, measure the current concentration, record it (and tell that if you are heavy cutting or fine cutting, you can increase the concentration of the product in time to achieve cutting quality).

d) Take a pH test strip or pH meter, measure the pH value, and record it (and inform that bacteria are the least able to breed in the case of bacteria, and more than 10 may cause bite paint).

e) Take out the transparent PET bottle, put it into the cutting fluid in the paper cup, and show the defoaming to the customer.

f) Take out the nitrite test strip to prove that the product of LZ is nitrite-free.

The above is what you will do when you visit your customers, and I would like to share it with you here.

Shanghai Jianqing Zhang Bokai.

Clean the oil sump, then just mix your oil proportionally with water and try it.

1. You can test according to the relevant provisions of GB T6144-2010 "Synthetic Cutting Fluid".

2. The main properties are, nitrite, pH, stability, rust resistance, corrosiveness and so on. In addition, water-based products also have an anti-rust test that is more important, IP287 cast iron powder method. The above is basically the testing standard of cutting fluid.

Cutting fluid is mainly used in turning, grinding, milling, planing and other processes in metal processing, especially suitable for cast iron, carbon steel, bearing steel, copper and copper alloy, aluminum and aluminum alloy and other materials.

Usage: It is recommended to use a concentration of 10%, that is, slowly add 10 parts of the cutting fluid stock solution to 90 parts of water, and stir evenly into a working solution. The concentration of the working fluid is the basis for making full use of the functions of the cutting fluid. If the concentration is too low, it will affect the cutting function; If the concentration is too high, it will also affect the normal performance of the function and the phenomenon of sticky knives, if from the perspective of anti-corruption, the concentration should be increased appropriately.

For example: general microemulsions, laboratory spoilage experiments, when the concentration is 5%, it begins to deteriorate after 6 to 7 months; At a concentration of 10%, 10-12 months later, deterioration begins.

Electronic titrators for almost all requirements. Or find Castrol to solve.

1. First of all, it is necessary to select the correct cutting fluid according to the metal processing needs, materials, environment and equipment. In the case of metal processes, cutting fluids may have an impact on workers, the environment and their workpieces.

2. Designate and arrange employees to monitor the cutting fluid used, do a good job in the testing and registration of each data of the cutting fluid, and take immediate maintenance if problems are found.

3. If you find that the workpiece is rusted, smelly, and equipment leakage occurs in the process of using cutting fluid, please contact the cutting fluid manufacturer immediately and ask the manufacturer to dispatch technicians to approach the corresponding problems.

4. Please do a good job of properly disposing of the used cutting fluid waste liquid, and it is strictly forbidden to discharge it directly into the sewer pipeline, which will not only have a serious impact on the surrounding water quality, but also will be punished.

5. The storage of cutting fluid should pay attention to avoid light, heat and moisture, which is the key to avoid the deterioration of cutting fluid.

6. Outdoor storage should be sealed and stored to prevent rainwater from infiltrating and causing bacteria to breed and affect the use effect.

Fangchuan lubrication will answer for you:

1. It should be stored in a dark, heat and moisture room

2. The stored oil should be kept clean and clearly marked

3. If it must be temporarily placed outdoors, it must be covered with a rainproof cloth;

4. Keep the floor of the warehouse clean, so as to facilitate the timely detection of oil leakage

5. When the oil is out of the warehouse, it should follow the first-in, first-out;

6. The cutting fluid is not easy to mix with other oils

7. When the cutting fluid is replaced with a new one, the original liquid should be cleaned up and replaced with a new one.
