ʻO Rosina Ester

ʻO Harvest Enterprise e like me kekahi o nā mea hana a me ka hale hana China Rosin Ester, he ikaika ikaika mākou a me ka hoʻokele piha. Eia kekahi, loaʻa iā mākou ka laikini hoʻopuka ponoʻī. Hana nui mākou i ka hana ʻana i kahi ʻano Rosin Ester a pēlā aku. Hoʻopili mākou i ke poʻo o ka hoʻonohonoho maikaʻi a me ka mea nui o ka mea kūʻai aku, mahalo mākou i kāu mau leka, kelepona a me nā noiʻi no ka hui ʻoihana. Ke hōʻoiaʻiʻo nei mākou iā ʻoe i kā mākou lawelawe kiʻekiʻe i nā manawa āpau.

ʻO Rosin Ester ka polyol ester o ka waikawa ʻala. ʻO nā polyols maʻamau ka glycerin a me ka ductal tetraol. ʻO ka multi-mellow pine ester he māmā melemele mālohi. ʻO ka helu palupalu he 90-110 ° C, a ʻo ka waiwai waikawa he 10 a 20. Hoʻohana ʻia e hana i ka pena, ʻoi aku ka kiʻekiʻe o ka maikaʻi ma mua o ke kopa calcium rosin.

ʻOi aku ka kiʻekiʻe o ka wahi palupalu o nā esters elastic tetraraxyl ma mua o ka glycerin, i hana ʻia i ka hana maloʻo ma hope o ka varnish. ʻOi aku ka maikaʻi o ka hana o ka paʻakikī a me ka pale wai ma mua o ka varnish i hana ʻia me ka glycerin rosin. Inā hoʻemi ʻia ka ester pili i hana ʻia me ka polymer rosin a i ʻole ka ʻala hydride, e hoʻemi ʻia ke ʻano o ka discoloration, a ʻoi aku ka maikaʻi o nā hana ʻē aʻe. ʻOi aku ka kiʻekiʻe o ka wahi palupalu o nā splasses polymer ma mua o ka rosin, ʻoiai ke hoʻemi ʻia ka wahi palupalu o nā mea ʻala hydrogenated.
