CHANGE of NATURAL DECORATIVE PROPERTIES of WOOD. Thermoplastic coverings

Thermoplastic coverings . Facing coverings on the basis of polyvinylchloride films without a fabric basis possess high protective properties - chemical firmness to solutions of acids and alkalis, soap solutions, spirit, gasoline. They represent the sheet rolled material having depending on appointment a thickness from 0,2 to 0,8 mm and width of 1,2 m.

For facing of elements of furniture the films of PVC formed of following components are used: polymeric binding (polyvinylchloride suspenzionnyj marks РџР’РҐ-РЎ4 or РџР’РҐ-РЎ5); softener (dibutilftalat, dioktilftalat, GOST 8728-77); the stabilizer (stearat zinc, lead silicate) and pigments. In VPKTIMe a number of structures of films of PVC transparent and ukryvistyh various colour is received. Films are pasted by dispersive glue (emulsija vinilatsetata with dibutilmaleinatom and dispersion РњРҐ-30) on the prepared surface (glossy or imprinted).

The self-pasted films Р’Рђ-15 made on the basis of copolymer Р’Рђ-15 are developed For facing of panel board elements of furniture VPKTIMom, softeners, stabilizers and pigments. Films are made for transparent and ukryvistoj furnish of various colour. Napressovka films on a finished surface it is made in a hydraulic multiflying press.

In TSNIIFe are developed transparent and ukryvistye coverings of various colours on a basis polimetilmetakrilatnogo latex. Structures polimetilmetakrilatnogo latex put on a paper (weight 150 g/m2), impregnated with thermojet pitch.

Formation polimetilmetakrilatnyh coverings occurs in the course of pressing in hydraulic pressah to application polished, shlifovannyh or the engraved metal linings at rather low specific pressure (about 15 kgs/sm2).

Depending on cleanliness of a surface of linings coverings with the various invoice - smooth, glossy or matte or with relief drawing can be received. Coverings are recommended for internal furnish of the premises, the built in furniture, intraroom doors, etc.

For furnish of metal details of furniture by polymeric materials along with futerovkoj or plakirovaniem sheet materials jet methods - a gas-flame dusting, teploluchevoj, vortical and electrostatic have the greatest value.
