Emasimini amakhemikhali amahle nezinto zokwenziwa kwama-polymer, i-triethylefanimine (teda), ngokusebenza kwayo okuvelele okuvelele, kuyisisekelo esibalulekile ukuthuthukiswa kwezimboni ezinjenge-polyurethane. I-Dotachem Triethylediamine umkhiqizo inekhwalithi yobungcweti, isekela ukukhiqizwa kwamakhasimende omhlaba.

I-Dotachem ngumhlinzeki ochwepheshe wemikhiqizo yamakhemikhali eneminyaka eminingi yesipiliyoni ekunikezeni i-cyclohexanone ukuhweba kwangaphandle. Inikeza imikhiqizo ezinzile futhi eziguquguqukayo ze-cyclohexanone kumakhasimende womhlaba wonke ngamazinga aqinile wekhwalithi, okwenza umkhiqizo wokukhiqiza ezimbonini ezahlukahlukene.

Imboni yamakhemikhali yama-22nd International International yayibanjelwe eShanghai kusukela ngoSepthemba 17 kuya ku-19, 2025. Inkampani yaseDotachem idonsele ukunakwa kwezivakashi eziningi ezinemininingwane esezingeni eliphakeme nezinsizakalo ezifanelekile emakethe yamakhemikhali e-Global.

INonyPhenol iyinto ebalulekile eluhlaza enamakhemikhali eluhlaza okotshani osebenza kahle, futhi sekuyinto ebalulekile emaketangeni okukhiqiza ezimboni eziningi. UDotachem ubandakanyeke ekuthengisweni kwamakhemisela kwamakhemikhali iminyaka eminingi. Imikhiqizo yeNonyphenol enikezelayo iwine ukuthembeka kwamakhasimende omhlaba ngekhwalithi yawo yokuzinza nokusebenza.

I-Dichloroethane (DCE) iyingxenye ebalulekile ye-hydrocarbon enezakhiwo zamakhemikhali eziyingqayizivele futhi iyinto ebalulekile eluhlaza ezinhlakeni eziningi zokukhiqiza izimboni. I-Dotachem ingumhlinzeki wemikhiqizo yamakhemikhali ochwepheshe, enikeza imikhiqizo esezingeni eliphakeme ye-Dichloroethane ukufeza izidingo zokukhiqiza zamakhasimende ezinhlobonhlobo zezimboni.

I-Paraformaldehyde iyi-polymer ye-formaldehyde, eyethula njengempuphu emhlophe noma ama-granule. Inezinzuzo ezinjengokuhlaselwa okuhle, ukuphendula okuphezulu, kanye nokugcina okulula nokuhamba. Lezi zici zikuvumela ukuthi zibambe iqhaza elibalulekile ezinkambeni eziningi zezimboni.
