Isingeniso

I-Hexamethyl-1,3,5-triazine (HMT) iyinhlanganisela yezinto eziphilayo. Kuyikristalu engenambala noma i-white crystalline powder, encibilika kuzincibilikisi zemvelo ezifana notshwala, ama-ketone, ama-ester, njll., futhi inyibilika kancane emanzini. I-Hexabutyridine inezakhiwo ze-stereoisomers, ezivame kakhulu kuzo ama-isomers amathathu: A, B, kanye no-C.

 

Lawa ma-isomer ahlukile ngemvelo nasekusetshenzisweni. Phakathi kwazo, uhlobo A lunokuqina okuphezulu kokushisa namandla emishini, futhi kuvame ukusetshenziswa njengesengezo se-thermosetting resins, adhesives, coatings and preservatives. Uhlobo B nohlobo C zizinzile emazingeni okushisa aphansi kunoHlobo A futhi lungasetshenziswa njengezinciphisi zezincibilikisi, ama-surfactants, namadayi.

 

Indlela yokulungiselela i-hexabutyldine ngokuvamile yamukela ukusabela kwe-tricyandiamide ne-formaldehyde. Isinyathelo esiqondile ukujiya i-tricyandiamide ne-formaldehyde ngaphansi kwezimo zokusabela ezifanele ukuze kukhiqizwe i-hexabutydine. Ingase futhi ilungiswe ngezinye izindlela, njengokusabela kwe-condensation ye-aminocyanamide ngezinhlanganisela ze-ketone.

I-Hexabutyridine inobuthi obuthile, ukuthintana nesikhumba kanye nokuhogela kungabangela ukucasuka, ukuthintana isikhathi eside kanye nokuhogela kufanele kugwenywe. Izimpahla zokuzivikela ezifanele njengamagilavu, izihlangu zobuso, nezibuko kufanele zigqokwe ngesikhathi sokusebenza. Lapho uyigcina, kufanele ibekwe endaweni epholile, engenawo umoya, kude nomlilo nama-oxidants.
