Cresol,formaldehyde,epichlorohydrinpolymer - Introduction
Formaldehyde is an organic compound with the chemical formula CH2O, which is a common organic solvent and flame retardant. It has a pungent odor that can trigger respiratory and eye discomfort.
(Chloromethyl) oxirane is an epoxy resin prepared by the reaction of formaldehyde and vinyl chloride. It has excellent physical properties and chemical resistance, and is widely used in coatings, adhesives, plastics and other fields. Its polymer has excellent adhesion, wear resistance and corrosion resistance.
2-Methylphenol, chemical formula C7H8O, is an organic compound with a pungent odor. It can be used in the production of dyes, catalysts and preservatives. Polymers obtained by copolymerization with formaldehyde are often used as crosslinking agents in coatings and adhesives to provide abrasion and chemical resistance.
In the preparation method, formaldehyde can be obtained by oxidation of methane, while (chloromethyl) oxirane and 2-methylphenol can be prepared by corresponding chemical reactions. The polymers are prepared by copolymerization of formaldehyde and (chloromethyl) oxirane or 2-methylphenol.
When using formaldehyde and polymers, you need to pay attention to their safety. Formaldehyde is irritating and toxic. Inhalation of high concentrations will cause serious harm to the human body. Appropriate protective measures should be taken to maintain good indoor ventilation. The use of polymers should follow safe operating procedures, avoid direct contact with skin and eyes, avoid inhalation of gas or dust, so as not to cause discomfort or damage to health.
