E aʻo e pili ana i ka hoʻololi ʻana i ke kiʻi i hōʻike ʻia

E aʻo e pili ana i ka hoʻololi ʻana o ka wai i ka wai Alkyd Resin Coatings

ʻO ka wehewehe pōkole:

Ua lilo ʻo Alkyd resin coating i hoʻokahi o nā mea i hoʻopaʻa ʻia a hana ʻia i loko o ka ʻoihana uhi ma muli o ka maʻalahi o ka loaʻa ʻana o nā mea maka, ke kumu kūʻai haʻahaʻa a me ka nani maikaʻi, ka maʻalahi a me ka pili.Eia nō naʻe, he mau hemahema ko ka alkyd resin coating e like me ka haʻahaʻa haʻahaʻa haʻahaʻa, ka pale wai a me ka wela, a ʻaʻole hiki i kāna noi ke hoʻokō i nā koi o ka hoʻomohala ʻoihana no ka hana kiʻekiʻe.He mea nui ia e hoʻololi a hoʻonui i ke kahua noi o ka uhi resin alkyd.

I kēia manawa, ʻelua mau ʻano o ka noiʻi e pili ana i ka hoʻololi ʻana i nā uhi resin alkyd: ka hoʻololi resin a me ka hoʻololi puaʻa.ʻO ka hoʻololi ʻana o Resin ka hoʻolauna ʻana i nā hui ʻē aʻe ma ka ʻāpana kaulahao resin molecular, a i ʻole me ka resin polyurethane, resin acrylic, resin epoxy a me ka resin silicone.ʻO ka hoʻololi ʻana o ka puaʻa a me ka mea hoʻopihapiha ka mea nui e hoʻohui i nā puaʻa hana like ʻole a me nā mea hoʻopihapiha e hoʻomaikaʻi ai i ka hana o nā coatings resin alkyd.Hoʻopuka kēia pepa i ke aʻo ʻana i ka hoʻololi ʻana o ʻelua mau uhi wai alkyd resin.

E aʻo e pili ana i ka hoʻololi ʻana o ka wai i ka wai Alkyd Resin Coatings

1. Ka hoomakaukau ana i ka aila-wai alkyd resin mai na hua Zanthoxylum bungeanum ma o ka hoohiolo ana i na omole polyethylene terephthalate (PET).
Ua hoʻomākaukau ʻo Lei Rui o ke Kulanui o Shaanxi o ka ʻepekema a me ka ʻenehana, a me nā mea ʻē aʻe i kahi holoholona i hoʻololi ʻia i ka aila-wai alkyd resin o Zanthoxylum bungeanum anoano ma ka hoʻohana ʻana i nā ʻōmole PET ʻōpala, trimethylolpropane (TMP) a me ka ʻaila hua Zanthoxylum bungeanum non edible ma ke ʻano he kumu kumu, phthalic anhydride ( PA) ma ke ano he monomer acidic, 2,2-Dimethylolpropionic acid (DMPA) ma ke ano he monomer wai, a me n, N-Dimethylethanolamine ma ke ano he mea hookikina.Hōʻike nā hopena hōʻike hoʻokō o ka uhi ʻana i ka wā i 11.5% ka nui o ka waiʻona, 50% ka ʻaila ʻaila, w (PET) = 9.3%, w (DMPA) = 10%, ʻoi aku ka maikaʻi o ka mālama ʻana i ka wai, a me ka wai. ʻoi aku ka maikaʻi o ke kūpaʻa, ka paʻakikī a me ke kūpaʻa wela ke hoʻohālikelike ʻia me ka alkyd wai maʻamau.
2. Silicone acrylate polyurethane i hoʻololi ʻia i ka wai alkyd anticorrosive coating
Hoʻomākaukau ʻia ka resin alkyd e ka esterification reaction me ka tall oil fatty acid (TOFA), pentaerythritol a me PA ma ke ʻano he kumu kumu, a laila ua hoʻohui ʻia ka emulsifier AE 300 no ka loaʻa ʻana o ka wai lotion alkyd dispersion.Ua hoʻomākaukau ʻia kahi prepolymer polyurethane wai mai ka diol dehydrated, isophorone diisocyanate a me ka wai monomer 2,2-dihydroxymethylpropionic acid (DMPA).Ua hoʻomākaukau ʻia ka lotion polyurethane silikonika ma ka hoʻohana ʻana i ka TEA ma ke ʻano he neutralizing agent, hoʻohui i ka monomer acrylic, emulsifier, silane coupling agent, initiator a me ka mea hoʻonui kaulahao.Ua hoʻomākaukau ʻia kahi ʻāpana alkyd wai i hoʻololi ʻia me ka wai aqueous alkyd dispersion a me ka silicone acrylic polyurethane lotion ma ke ʻano he mea hana kiʻiʻoniʻoni nui.
