Hoʻolauna

ʻO Hexamethyl-1,3,5-triazine (HMT) he mea hoʻohui kino. He aniani kala ʻole a i ʻole ka pauka keʻokeʻo keʻokeʻo, hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me nā ʻona, ketones, esters, etc., a hiki ke hoʻoheheʻe ʻia i ka wai. Loaʻa i ka Hexabutyridine nā waiwai o nā stereoisomers, ʻo ka mea maʻamau ʻekolu isomers: A, B, a me C.

 

ʻOkoʻa kēia mau isomers i ke ʻano a me ka hoʻohana. I waena o lākou, ʻo ke ʻano A he paʻa wela kiʻekiʻe a me ka ikaika mechanical, a hoʻohana pinepine ʻia i mea hoʻohui no nā resins thermosetting, adhesives, coatings a me nā preservatives. ʻOi aku ka paʻa o ke ʻano B a me ke ʻano C i nā wela haʻahaʻa ma mua o ka Type A a hiki ke hoʻohana ʻia ma ke ʻano he mau mea waena no nā solvents, surfactants, a me nā mea pena.

 

ʻO ke ʻano o ka hoʻomākaukau ʻana i ka hexabutyldine e hoʻohana maʻamau i ka hopena o triyandiamide a me formaldehyde. ʻO ka hana kikoʻī ʻo ka condense triyandiamide a me formaldehyde ma lalo o nā kūlana hopena kūpono e hana ai i ka hexabutydine. Hiki ke hoʻomākaukau ʻia e nā ʻano hana ʻē aʻe, e like me ka hopena condensation o aminocyanamide me nā pūhui ketone.

He mea make ka Hexabutyridine, pili me ka ʻili a me ka inhalation hiki ke hoʻonāukiuki, hoʻopaʻa lōʻihi a me ka inhalation pono e pale ʻia. Pono e hoʻohana ʻia nā mea pale kūpono e like me nā mīkina lima, nā pale maka, a me nā maka aniani i ka wā o ka hana. I ka wā e mālama ai, pono e waiho ʻia ma kahi ʻoluʻolu a me ka ea, kahi mamao mai ke ahi a me nā oxidants.
