Phunzirani Pa Kusintha Kwa Utoto Kwa Zopaka Zamadzi Za Alkyd Resin

Kufotokozera Kwachidule:

Kupaka utomoni wa Alkyd kwakhala imodzi mwazofunda kwambiri komanso zopangidwa mumakampani opanga zokutira chifukwa cha kupezeka kwake kosavuta kwa zopangira, mtengo wotsika komanso gloss wabwino kwambiri, kusinthasintha komanso kumamatira.Komabe, zokutira zachikhalidwe za alkyd resin zimakhala ndi zovuta zina monga kuuma kwa ❖ kuyanika, kukana madzi ndi kukana kutentha, ndipo kugwiritsa ntchito kwake sikungakwaniritse zofunikira za chitukuko cha mafakitale kuti zitheke.Ndikofunikira kusintha ndikukulitsa gawo logwiritsa ntchito zokutira alkyd resin.

Pakalipano, pali mbali ziwiri mu kafukufuku wokhudza kusinthidwa kwa zokutira za alkyd resin: kusintha kwa utomoni ndi kusintha kwa pigment.Kusintha kwa utomoni ndikudziwitsa magulu ena pagawo la utomoni wa molekyulu, kapena ndi polyurethane resin, acrylic resin, epoxy resin ndi silicone resin.Kusintha kwa pigment ndi filler makamaka ndikuwonjezera mitundu yosiyanasiyana yogwira ntchito ndi zodzaza kuti zithandizire kukonza bwino kwa zokutira za alkyd resin.Pepalali likuwonetsa kafukufuku wokhudza kusinthidwa kwa zokutira ziwiri zokhala ndi madzi alkyd resin.

Phunzirani Pa Kusintha Kwa Utoto Kwa Zopaka Zamadzi Za Alkyd Resin

1. Kukonzekera kwa mafuta a alkyd resin kuchokera ku mbewu za Zanthoxylum bungeanum powononga mabotolo a polyethylene terephthalate (PET)
Lei Rui wa Shaanxi University of Science and Technology, etc. anakonza Pet kusinthidwa mafuta-madzi alkyd utomoni wa mbewu Zanthoxylum bungeanum pogwiritsa ntchito zinyalala PET mabotolo, trimethylolpropane (TMP) ndi osadible Zanthoxylum bungeanum mbewu mafuta monga zopangira zazikulu, phthalic anhydride ( PA) monga acidic monomer, 2,2-Dimethylolpropionic acid (DMPA) monga monoma wamadzimadzi, ndi n, N-Dimethylethanolamine monga wothandizira neutralizing.Zotsatira zoyeserera za zokutira zikuwonetsa kuti mowa ukakhala 11.5%, mafuta ndi 50%, w (PET) = 9.3%, w (DMPA) = 10%, zokutira zimakhala ndi kukhazikika kosungirako bwino, komanso madzi. kukana, kuuma ndi bata matenthedwe bwino kwambiri poyerekeza ndi wamba alkyd amadzimadzi.
2. Silicone acrylate polyurethane kusinthidwa madzi alkyd anticorrosive zokutira
Utomoni wa alkyd udakonzedwa ndi esterification reaction ndi tall oil fatty acid (TOFA), pentaerythritol ndi PA ngati zida zazikulu zopangira, ndiyeno emulsifier AE 300 idawonjezedwa kuti apeze kubalalitsidwa kwamadzi odzola alkyd.Amadzimadzi polyurethane prepolymer anakonzedwa kuchokera dehydrated diol, isophorone diisocyanate ndi amadzimadzi monomer 2,2-dihydroxymethylpropionic acid (DMPA).Silicon acrylic polyurethane lotion idakonzedwa pogwiritsa ntchito TEA monga neutralizing agent, kuwonjezera acrylic monomer, emulsifier, silane coupling agent, initiator ndi chain extender.Chophimba cha silikoni cha acrylic polyurethane chosinthidwa chamadzi alkyd chinakonzedwa ndi kubalalitsidwa kwamadzi alkyd ndi silicone acrylic polyurethane lotion ngati zida zazikulu zopangira filimu.
