Urea Formaldehyde Resin Production Facility

We manufacture these facilities on a turnkey basis. We produce turnkey systems.

- This project includes the production of formaldehyde, urea-formaldehyde pre-condensate (UFC-80), and urea-formaldehyde resins used as adhesives for particle board, plywood, MDF, as well as paper impregnation.

     A -) Production of formaldehyde and UFC-80.

     B -) Urea-Formaldehyde production. (MDF)

     C -) Production of impregnating resin materials.

     D -) Storage and preservation.

A - FORMALDEHYDE PRODUCTION

Formaldehyde is produced as a result of the oxidation of methanol with oxygen.

      CH3OH + ½ O2 ..............................CH2O + H2O + 38 Kcal

Methanol and formaldehyde are sent in vapor form to the oxidation reactor.

There are 14,000 tubes in the formaldehyde oxidation reactor, and these tubes contain iron molybdenum oxide as a catalyst.

Methanol is converted to formaldehyde as it passes through the catalyst. Formaldehyde is sent to the absorption column to obtain a solution.

Water or urea solution is supplied to the absorption column. If the production of UFC-80 absorption column is needed, it should be supplied together with urea solution.

B - UREA-FORMALDEHYDE PRODUCTION (MDF)

Formaldehyde enters special reactors. Adjusting the pH is the first step of urea loading.

In the reactor, methylol groups occur after the condensation reaction with basic pH and acidic pH.

After the acidic reaction, the second urea must be added. It needs to take water with a vacuum system to adjust the solid content.

If powder urea-formaldehyde is needed without vacuum product, it is sent to the waiting tank and then to the spray drying column.

CH2O + 2HN-CO-NH2 ... OHCH2-NH-CO-NH2 Monomethylol urea

+ CH2O ...... OHCH2-NH-CO-NH-CH2OH Dimethylol urea + Acid

NH2-CO-NH-CH2-NH-CO-NH-

C - IMPREGNATION RESIN PRODUCTIONS

There are two types of impregnating resins for decorative paper, coating, and balance paper.

Urea-Formaldehyde resin 50% Solid content

Melamine-Formaldehyde resin 54% Solid content

Formaldehyde solution can load the reactor and adjust the concentration with the process

After adding powder melamine and additives and heating up to 90 °C.

When the polymerization reaction is completed, the cooling process begins. Melamine-

Formaldehyde resin reaction requires a smaller reactor compared to urea-formaldehyde reactor.

(12-15 m3)

The production of impregnating urea-formaldehyde resin can be done in a large or small similar reactor.

D - APPLICATIONS AND STORAGE

Raw material and product storage tanks, cooling system, steam generator,

Electric transformer, process water treatment, air filter, etc.

Formaldehyde Factory

The main raw material for formaldehyde production is methanol. Methanol is produced from natural gas.

The second material is iron molybdenum oxide catalyst. Methanol can hold carbon steel tanks.

Adhesive plants require more raw material than the Formaldehyde factory.

The main raw material is formaldehyde, which produces formaldehyde. The second main raw material is urea.

Other chemicals:

Melamine, Caprolactam, diethylene glycol, formic acid, caustic soda, sulfuric acid, ammonia, ammonium sulfate, and ammonium chloride.

It is possible to produce powder melamine-formaldehyde resin in decorative paper manufacturing.

Regnation. Chemicals as above (melamine, diethylene glycol, caprolactam) can be used

for melamine-formaldehyde resins.
