Kwiga Kubijyanye na Resin Guhindura Amazi ya Alkyd Resin Coatings
Ibisobanuro
Kugeza ubu, hari ibintu bibiri mubushakashatsi bwerekeranye no guhindura alkyd resin coatings: guhindura resin no guhindura pigment.Guhindura resin ni ukumenyekanisha andi matsinda kumurongo wa resin ya molekuline, cyangwa hamwe na resin ya polyurethane, resin acrylic, epoxy resin na silicone resin.Guhindura pigment nuwuzuza ni ukongeramo pigment zitandukanye zikora hamwe nuzuza kugirango tunoze imikorere ya alkyd resin.Uru rupapuro rutangiza ubushakashatsi ku guhindura ibice bibiri byamazi ya alkyd resin.
Kwiga Kubijyanye na Resin Guhindura Amazi ya Alkyd Resin Coatings
1. Gutegura amavuta-amazi alkyd resin ivuye mu mbuto za Zanthoxylum bungeanum no kwangiza amacupa ya polyethylene terephthalate (PET).
Lei Rui wo muri kaminuza yubumenyi n’ikoranabuhanga ya Shaanxi, nibindi yateguye amatungo yahinduwe amavuta-amazi alkyd resin yimbuto za Zanthoxylum bungeanum akoresheje amacupa ya PET, trimethylolpropane (TMP) hamwe n amavuta yimbuto ya Zanthoxylum bungeanum aribikoresho byingenzi, anhydride ya phalale (anhydride); PA) nka monomer acide, 2,2-Dimethylolpropionic aside (DMPA) nka monomer y'amazi, na n, N-Dimethylethanolamine nkibikoresho bitesha agaciro.Ibisubizo byikizamini cyibisubizo byerekana ko iyo inzoga zifite 11.5%, amavuta arimo 50%, w (PET) = 9.3%, w (DMPA) = 10%, igifuniko gifite ububiko bwiza, n'amazi kurwanya, gukomera hamwe nubushyuhe bwumuriro byateye imbere cyane ugereranije na alkyd isanzwe y'amazi.
2. Silicone acrylate polyurethane yahinduwe mumazi ya alkyd anticorrosive coating
Alkyd resin yateguwe na esterification reaction hamwe na aside irike yamavuta (TOFA), pentaerythritol na PA nkibikoresho nyamukuru, hanyuma emulifier AE 300 yongerwaho kugirango ibone amavuta yo kwisiga alkyd.Prepolymer y'amazi ya polyurethane yateguwe muri diol idafite umwuma, isophorone diisocyanate na monomer yo mu mazi 2,2-dihydroxymethylpropionic aside (DMPA).Amavuta yo kwisiga ya Silicon acrylic polyurethane yateguwe akoresheje TEA nkumukozi utabogama, wongeraho acrylic monomer, emulsifier, umukozi wa silane, intangiriro nuwagura urunigi.Silicone acrylic polyurethane yahinduwe ya alkyd yamazi yo mumazi yateguwe hamwe no gukwirakwiza amazi ya alkyd hamwe na silicone acrylic polyurethane amavuta yo kwisiga nkibikoresho byingenzi bya firime.
