1. Nkwadebe mmanụ-mmiri alkyd resin sitere na mkpụrụ osisi Zanthoxylum bungeanum site na mmebi nke karama polyethylene terephthalate (PET).
Lei Rui nke Mahadum Shaanxi nke sayensị na teknụzụ, wdg kwadebere anụ ụlọ gbanwetụrụ mmanụ-mmiri alkyd resin nke mkpụrụ osisi Zanthoxylum bungeanum site na iji karama PET n'efu, trimethylolpropane (TMP) na mmanụ mkpụrụ osisi Zanthoxylum bungeanum anaghị eri nri dị ka isi akụrụngwa, phthalic anhydride ( PA) dị ka monomer acidic, 2,2-Dimethylolpropionic acid (DMPA) dị ka monomer mmiri, na n, N-Dimethylethanolamine dị ka onye na-ewepụ ihe.Nsonaazụ ule arụmọrụ nke mkpuchi na-egosi na mgbe mmanya na-aba n'anya bụ 11.5%, mmanụ mmanụ bụ 50%, w (PET) = 9.3%, w (DMPA) = 10%, mkpuchi nwere ezigbo nkwụsi ike nchekwa, na mmiri. A na-emeziwanye nguzogide, isi ike na nkwụsi ike ọkụ ma e jiri ya tụnyere alkyd nkịtị.
2. Silicone acrylate polyurethane gbanwetụrụ waterborne alkyd anticorrosive mkpuchi
A kwadebere resin alkyd site na mmeghachi omume esterification na ogologo mmanụ fatty acid (TOFA), pentaerythritol na PA dị ka isi akụrụngwa, wee tinye emulsifier AE 300 iji nweta mmiri mmiri alkyd dispersion.A kwadebere polyurethane prepolymer mmiri mmiri site na diol dehydrated, isophorone diisocyanate na aqueous monomer 2,2-dihydroxymethylpropionic acid (DMPA).A kwadebere ude mmiri silicon acrylic polyurethane site na iji TEA dị ka onye na-ewepụ ihe, na-agbakwunye acrylic monomer, emulsifier, onye na-ahụ maka njikọta silane, onye mbido na ihe ndọtị yinye.A kwadebere ihe mkpuchi silicone acrylic polyurethane nke ejiri mmiri alkyd dispersion na silicone acrylic polyurethane ude mmiri dị ka isi ihe na-emepụta ihe nkiri.
