HFE 7200 solvent, is it harmful to inhale?

Harmless, the lethal dose of 7200 is 1 80 of the weight of the creature, you can calculate how much you inhale.

HFE-7100 is a colorless, clear, slightly odorous liquid substance, in which the content of methoxy-nonafluorobutane (C4F9OC3) is less than the non-volatile components, which is specially used to replace "ozone destructive" substances such as freon. The product is the least toxic of the new CFC substitute product family, with a time-weighted average limit of 600 ppm over an 8-hour average operating time.

It is mainly used in the cleaning of precision electronic instruments and medical equipment

3mtmnovectmhfe is a colorless transparent and low-viscosity, non-flammable, and very safe liquid.

The one who turns me is a pig.

It seems that smoking too much is harmful to the body!

Hello!We are happy to answer that 3M's NOVEC 7200 fluorinated fluid can be used to clean mobile phone motherboards to remove particles and other dirt from the surface. Its surface tension is low, the permeability is good, and it can enter some very small pores;Its compatibility with motherboards is very good, and it will not corrode the motherboard material;After cleaning, NOVEC-7200 can volatilize quickly without leaving any residue on the motherboard surfaceThis fluorinated solution has no flash point, very low toxicity, ODP value of 0 (does not destroy the ozone layer of the atmosphere), low greenhouse effect value, and is a safe and environmentally friendly cleaning agent.

We hope you are satisfied with the above reply!If you still have questions, please feel free to ask the company.

It can be washed, so use it with confidence.

Intermediate processes of machining, (cleaning after stamping, cleaning after machining, cleaning before heat treatment, cleaning after stretching, cleaning before brazing, cleaning before coating) In order to protect the environment, Shanghai Baptist provides the most environmentally friendly cleaning process, combined with European cleaning technology. Shanghai Baptist inducts the cleaning process of the intermediate process of machining.

Shanghai Baptist Ultrasound recommends you:

1) Water-based cleaning machine process: The degreaser can use the most environmentally friendly electrolyzed water (strong alkaline type and strong acid type: ionized method).

Spray Cleaning, Spray Rinsing, Air Cutting, Drying.

Ultrasonic cleaning (alkali degreasing, ultrasonic rinsing (washing), 6. Anti-rust, air cutting, drying.

Ultrasonic cleaning (alkali degreasing, ultrasonic rinsing (washing), 6. Anti-rust, air cutting, drying.

2) Solvent cleaning machine process.

Flammable solvents: hydrocarbons and modified alcohols.

Multi-tank washer: immersion cleaning, ultrasonic rinsing, ultrasonic rinsing, vacuum drying.

Advantages: high efficiency. Box 8-12 h

Disadvantages: Solvent consumption is more.

Shanghai Baptist recommends:

Single-cavity multi-stage cleaning machine: immersion cleaning, ultrasonic rinsing, vacuum steam cleaning, vacuum drying.

Pros: Inefficiency. 4-8 box h

Disadvantages: The solvent consumption is relatively small, with an annual consumption of 1-2 barrels of 200L.

Non-flammable solvents: chlorinated solvents and fluorinated liquids are slightly more toxic than flammable solvents.

Such as trichloroethylene, tetrachloroethylene, fluorinated solution (HFE-7200 XF, XS, MCA).

Multi-tank washer: immersion cleaning, ultrasonic rinsing, steam cleaning, freeze drying.

Advantages: high efficiency. Box 12-20 h

Disadvantages: Solvent consumption is more. Monthly consumption of 10-20 barrels 200L.

Shanghai Baptist recommends:

Single-cavity multi-stage cleaning machine: immersion cleaning, ultrasonic rinsing, vacuum steam cleaning, vacuum drying.

Pros: Inefficiency. Box 8-12 h

Disadvantages: The solvent consumption is relatively small, with an annual consumption of 2-4 barrels of 200L.

Count, but you can't make a lot of money by just machining.

Shin-Etsu 178 Anti-Fingerprint Oil:

It is a kind of fluorine-containing coating formulated by fluorosilicone resin with a special structure, and the oral term of chemical experts is generally heptafluorosundotriethoxysilane, which is named according to the molecular structure combination of the product.

Preparation of anti-fingerprint oil solution:

With appropriate solvent dilution, the recommended dilution ratio is the mass ratio), the recommended diluent (solvent) includes:

One. 3m of HFE-7200, HFE-7100, and fluorinated solution Fluorinert FC-77;

Two. Semcon Chemical's HFE series: F-8632, F-8603, F-8605, F-8608, F-8610;

Three. Perfluoroalkanes, such as perfluorohexane, perfluorohexane, perfluorooctane, etc.
