Urea -formaldehyde resins are characterized by their low cost and availability of raw materials, so that in all cases when the stability of the glue seam is not required to the effects of sharp fluctuations in temperature and humidity, it is advisable to use such resins. The initial materials for the production of urea -formaldehyde resins (urea and formalin) are produced by the industry of severe organic synthesis. At the same time, the consumer of these resins is the furniture and woodworking industry, the enterprises of which are located mainly away from the centers of the chemical industry. Due to the wide implementation of synthetic binders, the issue of their transportation inevitably arises. The largest woodworking enterprises, such as the Izhora and Kostopol plants, the Kiev furniture factory named after Bozhenko, produce tar on the spot from imported raw materials. The resin produced by the enterprises of the chemical industry is transported in the form of a vacuum water emulsion. There is another possibility of obtaining a resin centralized production of powdered carbamide resin with a moisture content of 4-5 °/oh-equal volume of transportation of material in different transport solutions, based on the transported useful cargo.
