Polyurethane varnish - o se mea faamaeʻaina po nei

O le atiina ae o tekinolosi i ona po nei mo le tuuina atu o le faamaeaina o mea e mafai ai ei maua uma oloa fou ma fou ma se aofai o meatotino tulaga ese. O novelties faatatau lacquer polyurethane.

O lenei vaega e suitulaga i se fofo eseese tuufaatasiga o isocyanates hydroxyl polyfunctional. lacquer Polyurethane pe a faaaoga pepa i luga o polymer mautu ma fausaga e faatafa-tolu. O lenei faagasologa e tupu ona o le tali mai a isocyanates ma vaega hydroxyl (atoatoa polyesters maua e ala i le tali mai a se sili atu o le ava malosi polyhydric ma se acid dibasic po o le faafefiloi o le monobasic ma dibasic acids puta).

E masani ona faaaogaina ma vaega hydrolyzed acetates polyvinyl, le atoatoa polyacetals, esters cellulose, ma phenol-formaldehyde ksilolformaldegidnye resin. I totonu o le isocyanates faaaogaina sili ona masani ona faaaogaina diisocyanate ma eseese faafefiloi ai. Foi, faaaoga hexamethylene diisocyanate ma le oloa tali o diisocyanate sili ma se ava malosi polyhydric ma polyesters hydroxyl o loo i ai. Le galulue faatasi ma nei mea e manaomia ai puipuiga faapitoa. O lea sili atu faatino e faaaoga "punitia" po o le "natia" isocyanates, tuufaatasi lea e faigofie ona decomposed pe a tele. O lenei vaega e aofia ai le oloa tali o isocyanates ma malonic, ester acetoacetic, ethyleneimine ma feniluretanom. faataapeina lacquers Polyurethane faaaogaina esters, ketones, hydrocarbons chlorinated, nitroparaffins. O nei meafaigaluega diluent o xylene, toluene, hydrocarbon aliphatic.

o loo maua lacquers Polyurethane o se tasi-vaega po o fatuga e lua vaega. I le tulaga lona lua eseese saunia fofo o tuufaatasi hydroxyl-o loo i ai, po o le faafefiloi o nei tuufaatasi ma fofo isocyanate ao lei faaaogaina lenei sooupu ua fefiloi. O a saunia lacquer lua vaega o loo tausia mai le 4 i le 48 itula. O coatings o loo faaaogaina mo le ufiufi o maopo vevela ma le malulu. Faatapulaaina manatu fale o manu coatings vevela-faamalolo e tasi le vaega o faia i luga o le faavae lea e faapea o "punitia" isocyanates.

avea ma varnish Polyurethane a iʻila, coatings ofuvae ma maaa maualuga, lelei adhesion, maualuga meatotino dielectric ma tetee vailaau. ua faateleina le faaaogaina mo le puipuiga o sima, uamea, o luga o laupapa ma ua faaaoga mo valiina le meafaigaluega o vailaau, laau smelting ma faamamaina, i pisinisi meaai.

polyurethane maua varnish mo parquet, meafale, paʻu, pepa, paʻu, fausaga i vaa, ie e gaosia ma le uga. O lenei ufiufi e matua anagata ma le aoga, e faateleina ai tele le olaga fata o mea eseese. coatings tasi vaega e masani ona faaaoga mo le puipuiga o le apamemea, oloa alumini ma uamea.

vai polyurethane Varnish puipuia le puipui laupapa ma le faʻalo o mamanu ma mildew. E le o lava le malamalama ma le mafanafana-e tetee. O lenei -O le manino e mafai ai atoatoa faailoga i le matagofie faanatura o le fafie.
