[Nā Waiwai Kemika]

Aia ka toluene diisocyanate i ʻelua mau ʻano isomeric (2,4-toluene diisocyanate a me 2,6-toluene diisocyanate), nona nā waiwai like a me nā hopena. Hana ʻia ka toluene diisocyanate ma ke ʻano he hui 80:20 (2,4-toluene diisocyanate:2,6-toluene diisocyanate) o nā isomers ʻelua. Ma ka mahana o ka lumi, he wai melemele maopopo ka hui ʻana me kahi ʻala ʻoi a ʻawaʻawa. Pono e mālama ʻia ma lalo o ka friji, kahi mamao aku mai ka mālamalama a me ka makū i loko o kahi pahu paʻa i loko o kahi lewa inert. ʻAʻole hiki ke hoʻoheheʻe ʻia ka toluene diisocyanate i ka wai a hiki ke hui pū ʻia me ka hapa nui o nā mea hoʻoheheʻe organik maʻamau. Hana ʻia ka toluene diisocyanate ma ka hana ʻana i ka toluene diamine me ka carbonyl chloride (phosgene). Hoʻohana pinepine ʻia ka toluene diisocyanate ma ke ʻano he kemika waena i ka hana ʻana o nā polyurethane foams, elastomers, a me nā coatings, nā pena, nā varnishes, nā wire enamels, nā sealant, nā adhesives, a me nā mea hoʻopaʻa. Hoʻohana ʻia hoʻi ia ma ke ʻano he mea hoʻopili i ka hana ʻana o nā polymers nylon. Hoʻohana ʻia ʻo 2,4-Toluene diisocyanate ma ke ʻano he kemika waena i ka hana ʻana o nā huahana polyurethane, e like me nā foams, coatings, a me nā elastomers.

[Nā Hoʻohana]

I ka hana ʻana i nā foams polyurethane a me nā elastomers ʻē aʻe.

ʻO ka hānō hana ke kumu nui o nā maʻi hanu e pili ana i ka hana ma ka honua ʻoihana. ʻO Toluene-2,4-diisocyanate (TDI) kekahi o nā mea hoʻonāukiuki hanu maʻamau e alakaʻi ana i ka hānō hana.

[Nā Hoʻohana]

ʻO TDI (toluene diisocyanate) kahi mea maka kumu koʻikoʻi o ka polyurethane. ʻO TDI kahi hui ʻana o 2,4-TDI a me 2,6-TDI ʻelua ʻano isomers, me 3 ʻano o nā papa i hoʻohana pinepine ʻia: TDI-80/20, TDI-100 a me TDI-65/35. Hoʻohana nui ʻia i ka hana ʻana o ka polyurethane foam palupalu a me nā uhi elastomer polyurethane, nā mea hoʻopili, a pēlā aku.

[Nā Hoʻohana]

ʻO Toluene-2,4-diisocyanate kekahi o nā isocyanates i hoʻohana nui ʻia. Hoʻohana ʻia ia i ka hana ʻana i nā hua urethane paʻa a maʻalahi hoʻi, nā elastomers, a me nā uhi. Ma waho aʻe o kona hoʻohana ʻana ma ke ʻano he hui maʻemaʻe, loaʻa ia ma ke kālepa ma ke ʻano he hui ʻana o 2,4- a me 2,6-isomers (80: 20% a me 65: 35% ratios, kēlā me kēia).
