Ukutadisha Ngokulungiswa Kwe-resin Kwezingubo Ezitholakala Ngamanzi I-Alkyd Resin Isithombe Esifakiwe

Isifundo Ngokuguqulwa Kwe-resin Kwezingubo Ezitholakala Ngamanzi I-Alkyd Resin

Incazelo emfushane:

I-alkyd resin coating isibe enye yezingubo ezifundwe kakhulu futhi ezikhiqizwa embonini yokumboza ngenxa yokutholakala kalula kwezinto zokusetshenziswa, intengo ephansi kanye ne-gloss enhle kakhulu, ukuguquguquka nokunamathela.Kodwa-ke, ukugqoka kwe-alkyd resin yendabuko kunezinye izinto ezimbi ezifana nobulukhuni bokunamathela obuphansi, ukumelana namanzi nokumelana nokushisa, futhi ukusetshenziswa kwayo akukwazi ukuhlangabezana nezidingo zokuthuthukiswa kwezimboni zokusebenza okuphezulu.Kubalulekile ukuguqula nokwandisa inkambu yesicelo se-alkyd resin coating.

Njengamanje, kunezici ezimbili ocwaningweni lokuguqulwa kwezingubo ze-alkyd resin: ukuguqulwa kwe-resin nokuguqulwa kwe-pigment.Ukuguqulwa kwe-resin ukwethula amanye amaqembu engxenyeni ye-resin molecular chain, noma nge-polyurethane resin, i-acrylic resin, i-epoxy resin ne-silicone resin.Ukuguqulwa kwe-pigment ne-filler ngokuyinhloko ukufaka imibala ehlukene yokusebenza kanye nezigcwalisi ukuze kuthuthukiswe ukusebenza kwezingubo ze-alkyd resin.Leli phepha lethula ucwaningo ngokuguqulwa kwezingubo ezimbili ze-alkyd resin eziphuma emanzini.

Isifundo Ngokuguqulwa Kwe-resin Kwezingubo Ezitholakala Ngamanzi I-Alkyd Resin

1. Ukulungiswa kwe-alkyd resin yamanzi kawoyela evela kumbewu ye-Zanthoxylum bungeanum ngokucekelwa phansi kwamabhodlela e-polyethylene terephthalate (PET)
U-Lei Rui wase-Shaanxi University of science and technology, njll. ulungise i-alkyd resin eguquliwe kawoyela emanzini ye-Zanthoxylum bungeanum ngokusebenzisa imfucuza yamabhodlela e-PET, i-trimethylolpropane (TMP) namafutha embewu ye-Zanthoxylum bungeanum angadliwa njengezinto zokusetshenziswa eziyinhloko, i-phthalic anhydride ( PA) njenge-acidic monomer, i-2,2-Dimethylolpropionic acid (DMPA) njenge-monomer enamanzi, kanye ne-n, i-N-Dimethylethanolamine njenge-ejenti engathathi hlangothi.Imiphumela yokuhlolwa kokusebenza kwe-coating ibonisa ukuthi lapho okuqukethwe kotshwala kungu-11.5%, okuqukethwe kukawoyela kungu-50%, w (PET) = 9.3%, w (DMPA) = 10%, i-coating inokuqina okuhle kwesitoreji, futhi amanzi ukumelana, ubulukhuni kanye nokuzinza okushisayo kuthuthukiswa kakhulu uma kuqhathaniswa ne-alkyd evamile enamanzi.
2. I-silicone acrylate polyurethane modified waterborne alkyd anticorrosive coating
I-alkyd resin yalungiswa ngokusabela kwe-esterification nge-tall oil fatty acid (TOFA), i-pentaerythritol ne-PA njengezisetshenziswa zokusetshenziswa eziyinhloko, kwase kwengezwa i-emulsifier AE 300 ukuze kutholwe ukuhlakazeka kwamanzi kwe-alkyd.I-aqueous polyurethane prepolymer yalungiswa kusuka ku-diol dehydrated, isophorone diisocyanate kanye ne-aqueous monomer 2,2-dihydroxymethylpropionic acid (DMPA).I-Silicon acrylic polyurethane lotion yalungiswa kusetshenziswa i-TEA njenge-ejenti yokungathathi hlangothi, yengeza i-acrylic monomer, i-emulsifier, i-agent yokuhlanganisa i-silane, i-initiator kanye ne-chain extender.I-silicone acrylic polyurethane modified alkyd alkyd coating yalungiswa ngokuhlakazeka kwe-alkyd enamanzi kanye ne-silicone acrylic polyurethane lotion njengezinto eziyinhloko zokwakha ifilimu.
