Paraformaldehyde

Polyformaldehyde instead of ordinary industrial formaldehyde aqueous solution, in synthetic pesticides, synthetic resins, coatings and fumigation disinfectants and other a variety of formaldehyde downstream products, can not only reduce the energy consumption of dehydration, but also greatly reduce the amount of wastewater treatment, this is a green environmental protection project for the benefit of the country and the people. Low polymerization degree of paraformaldehyde because of its higher effective composition than industrial formaldehyde, is a solid particle, conducive to chemical, pharmaceutical and other chemical synthesis and other industrial applications, especially in the use of anhydrous formaldehyde as raw material synthesis, widely used. It can also be used as disinfectants, fungicides, fumigants and herbicides, as well as in the manufacture of resins and artificial ivory.

1.Main Usage

1, used as organic chemical, synthetic resin raw materials, also used as drug fumigant

2, polyformaldehyde for high formaldehyde content of solid formaldehyde, solid granular, easy storage and transportation. At a higher temperature can become formaldehyde vapor, easy to replace the high concentration of formaldehyde to participate in various reactions, is conducive to chemical, pharmaceutical and other chemical synthesis and other industrial applications, especially in the use of anhydrous formaldehyde as raw material synthesis, widely used.

There are mainly the following aspects:

(1) Pesticides: synthesis of acetochlor, butachlor and glyphosate;

(2) Paint: synthetic high-grade automotive paint;

(3) Resin: synthetic urea formaldehyde resin, phenolic resin, polyacetal resin, melamine resin, ion exchange resin and various adhesives;

(4) Papermaking: synthetic paper reinforcement;

(5) Casting: sanding defilm agent, synthetic casting adhesive;以上翻译结果来自有道神经网络翻译（YNMT）· 通用场景

(6) aquaculture industry: fumigation disinfectant;

(7) Organic raw materials: used to prepare pentaerythritol, trihydroxymethyl propane, glycerin, acrylic acid, methyl acrylate, methacrylic acid, n-hydroxymethyl acrylamide, alkyl phenol, methyl vinyl ketone, etc.;

(8) Others: medicine and disinfection.

3, used as sterilization agent, disinfectant, fumigant. Used in organic synthesis, pharmaceutical industry.
