Use of methyl acetal for methacetal equipment

Release date:2018-01-10 Author: Click:

 

(1) application in pesticide formulation. Most of the insecticides are chrysanthemum, pyrethrum, cypermethrin and deltamethrin, which are difficult to dissolve in the deodorizing kerosene and water base. Therefore, it is often used to dissolve the pesticides, such as dichloromethane, xylene, acetone and isopropanol. The solubility of pyrethroid is better than that of the above solvents, and the cost is low, and it can replace chlorine containing solvents.

2. Application in leather polishing agent and automobile polishing agent formulation. The formulation of leather polish usually uses a small amount of solid wax, microcrystalline paraffin, beeswax, and Brazil palm wax. It is often difficult to dissolve with dichloromethane, solvent gasoline and turpentine, and it is easy to delaminate and make the quality of the product unstable. The use of methyl acetal can improve solvent properties, improve quality, and fast volatilization, and easy to use. The same conditions exist in automobile polishing agent formulation, especially the water-soluble characteristics of the equipment, which plays a great role in improving the stability of emulsified wax.

(3) application in the formula of air freshener. At present, the essence of air freshener sold on the market usually uses ethanol as a solvent to dissolve with propane and uses more ethanol to affect the smell of fresh agent. The use of methyl acetal can greatly improve the solubility of flavor, reduce the amount of ethanol, improve the fragrance of fresheners and reduce the emission of VOCs. Especially for dry mist type air fresheners, the use of a small amount of methyl acetal can make the flavor propane mutually soluble, and better reflect the dry fog type of "dry".

4. Application in color ribbon formula. In the color band formula, polymer polyacrylic acid solid raw materials are mainly used, and F11 is used as solvent in the original formula. With the prohibition of freon, the use of methyl acetal as solvent will achieve good solubility and fast volatility.

It is used in the detergent formulation of electronic equipment. At present, F11 and F113 are used as the main raw materials in production. With the prohibition of freon, it will also be replaced by methyl acetal.

Methyl acetal can be used for the quantitative dissolution of fat, wax, nitro fiber, natural resin, rosin, TL oil, most synthetic resins, polystyrene, vinyl acetate polymers and copolymers, polyester, acrylic acid ester, polyamines, epoxy resin, chlorinated rubber, etc.

Mixing a small amount of methal with ethanol, ester or ketone can increase the efficiency of solvent. These characteristics make it especially suitable for paint and varnish formula, glue and adhesive, ink and all kinds of aerosol products, so that the product can obtain excellent homogeneous phase.

In addition, it can be used as a fuel additive. After adding, it can improve the combustion performance of the fuel significantly, reduce the emission of harmful gases, and can be used as a substitute for Freon in the air conditioner refrigerant.
