Ako Mo Te Resin Whakarerekētanga o Waterborne Alkyd Resin Coatings

Whakaahuatanga Poto:

Ko te paninga kapia Alkyd tetahi o nga paninga tino akohia me te whakaputa i roto i te umanga whakakikorua na te ngawari o te waatea o nga rawa mata, te utu iti me te tino kanapa, te ngawari me te piri.Heoi, ko te paninga kapia alkyd tuku iho he ngoikoretanga penei i te iti o te pakeke o te paninga, te aukati wai me te wera wera, a kaore e taea e tana tono te whakatutuki i nga whakaritenga o te whakawhanaketanga ahumahi mo te mahi nui.He mea nui ki te whakarerekē me te whakawhānui i te mara tono o te paninga kapia alkyd.

I tenei wa, e rua nga waahanga i roto i te rangahau mo te whakarereketanga o nga paninga kapia alkyd: ko te whakarereke kapia me te whakarereketanga pigment.Ko te whakarereketanga o te Resin he whakauru i etahi atu roopu i runga i te wahanga mekameka ngota kapia, me te kapia polyurethane, te kapia kiriaku, te kapia epoxy me te kapia silicone.Ko te whakarereketanga o te poaka me te whakakii ko te nuinga ki te taapiri i nga momo whakakao mahi me nga whakakii hei whakapai ake i te mahi o nga whakakikorua kapia alkyd.Ko tenei pepa e whakaatu ana i te rangahau mo te whakarereketanga o nga paninga kapia alkyd kawe wai e rua.

Ako Mo Te Resin Whakarerekētanga o Waterborne Alkyd Resin Coatings

1. Te whakarite i te kapia alkyd hinu-wai mai i nga kakano Zanthoxylum bungeanum ma te whakahekenga o nga pounamu polyethylene terephthalate (PET) ururua
Ko Lei Rui o te Whare Wananga o Shaanxi o te Putaiao me te Hangarau, me etahi atu, he mea whakarite mo te kapia alkyd hinu-wai o Zanthoxylum bungeanum kakano ma te whakamahi i nga ipu PET ururua, trimethylolpropane (TMP) me te hinu kakano Zanthoxylum bungeanum kore kai hei rauemi mata matua, phthalic anhydride ( PA) hei monomer waikawa, 2,2-Dimethylolpropionic acid (DMPA) hei monomer wai, me te n, N-Dimethylethanolamine hei kaihoko whakakore.Ko nga hua whakamatautau mahi o te paninga e whakaatu ana i te wa e 11.5% te waipiro o te waipiro, ko te hinu hinu he 50%, w (PET) = 9.3%, w (DMPA) = 10%, he pai te pupuri i te paninga, me te wai. he pai ake te atete, te pakeke me te waiariki ki te waiariki noa.
2. Ko te polyurethane acrylate acrylate kua whakarerekehia te paninga anticorrosive a-wai
I whakaritea te kapia alkyd e te tauhohenga esterification me te waikawa hinu hinu roa (TOFA), te pentaerythritol me te PA hei rauemi mata matua, katahi ka taapirihia te whakaemulsifier AE 300 ki te whiwhi i te wai whakakorikori alkyd wai.I whakaritea he polyurethane prepolymer wai mai i te diol maroke, te isophorone diisocyanate me te monomer aqueous 2,2-dihydroxymethylpropionic acid (DMPA).Ko te hinu polyurethane kiriaku Silicon i whakaritea ma te whakamahi i te TEA hei kaihoko whakakore, te taapiri i te monomer kiriaku, te whakaemulsifier, te kaihoko hono silane, te kaikokiri me te whakaroa mekameka.I whakaritea he paninga kiriaku polyurethane polyurethane kua whakarerekehia me te whakamararatanga alkyd wai me te hinu polyurethane kiriaku kiriaku hei rauemi hanga kiriata matua.
