Su'esu'ega i le Resin Suiga ole Waterborne Alkyd Resin Coatings

Fa'amatalaga Puupuu:

Alkyd resin coating ua avea ma se tasi o suʻesuʻega sili ona suʻesuʻeina ma gaosia i totonu o le fale faʻapipiʻi ona o le faigofie ona maua o mea mataʻutia, tau maualalo ma sili atu le susulu, fetuutuunai ma le pipii.Ae ui i lea, o le masani alkyd resin coating o loʻo i ai ni faʻafitauli e pei o le maualalo o le faʻafefeteina o le maaa, vai faʻafefe ma le vevela, ma o lona faʻaogaina e le mafai ona ausia manaʻoga o le atinaʻeina o fale gaosi oloa mo le maualuga.E taua tele le suia ma faʻalauteleina le faʻaogaina o le faʻaogaina o le alkyd resin coating.

I le taimi nei, e lua vaega i le suʻesuʻega i le suiga o le alkyd resin coatings: resin modification ma pigment modification.Resin suiga o le faʻalauiloaina o isi vaega i luga o le resin molecular filifili vaega, poʻo le polyurethane resin, acrylic resin, epoxy resin ma silicone resin.O le fesuiaiga o le pigmenti ma le faʻatumu e masani lava ona faʻaopoopo i ai pigments galue eseese ma faʻatumu e faʻaleleia ai le faʻatinoga o le alkyd resin coatings.O lenei pepa o lo'o fa'ailoa mai ai le su'esu'ega i le suiga o fa'alavalava resini alkyd e lua.

Su'esu'ega i le Resin Suiga ole Waterborne Alkyd Resin Coatings

1. Sauniuniga o le suau'u-vai alkyd resin mai fatu Zanthoxylum bungeanum e ala i le fa'aleagaina o otaota polyethylene terephthalate (PET) fagu.
Lei Rui o le Iunivesite o Shaanxi o le faasaienisi ma tekinolosi, ma isi. saunia se fagafao suia suauu-vai alkyd resin o Zanthoxylum bungeanum fatu e ala i le faaaogaina otaota PET fagu, trimethylolpropane (TMP) ma le suauu Zanthoxylum bungeanum fatu e le mafai ona taumafa e avea ma mea autu, phthalic anhydride ( PA) e pei o le monomer acidic, 2,2-Dimethylolpropionic acid (DMPA) e pei o le monomer vai, ma le n, N-Dimethylethanolamine e fai ma sui o le neutralizing.O faʻaiʻuga o suʻega faʻatinoga o le faʻapipiʻiina o loʻo faʻaalia ai pe a oʻo i le 11.5% le ava malosi, o le suauʻu e 50%, w (PET) = 9.3%, w (DMPA) = 10%, o le ufiufi e lelei le teuina, ma le vai. teteʻe, maaa ma mautu vevela e matua faʻaleleia pe a faʻatusatusa i le alkyd masani masani.
2. Silicone acrylate polyurethane fesuia'i waterborne alkyd anticorrosive coating
O le resin alkyd na saunia e ala i le esterification tali ma suauʻu umi gaʻo gaʻo (TOFA), pentaerythritol ma PA e avea ma mea autu autu, ona faaopoopo ai lea o le emulsifier AE 300 e maua ai le vai lotion alkyd dispersion.Na saunia se vai o le polyurethane prepolymer mai le diol dehydrated, isophorone diisocyanate ma le monomer aqueous 2,2-dihydroxymethylpropionic acid (DMPA).Silicon acrylic polyurethane lotion na saunia e ala i le faʻaaogaina o le TEA e fai ma sui e faʻafefe, faʻaopoopo le monomer acrylic, emulsifier, silane soʻotaga sui, initiator ma filifili extender.Sa saunia se fa'apipi'i fa'alkyd fa'afefeteina fa'ama'i fa'ama'i fa'alelei ma fa'ama'i fa'ama'i fa'ama'i fa'ama'i fa'ama'i.
