Mawu Oyamba

Hexamethyl-1,3,5-triazine (HMT) ndi organic pawiri. Ndi kristalo wopanda mtundu kapena woyera crystalline ufa, sungunuka mu zosungunulira organic monga alcohols, ketoni, esters, etc., ndipo pang'ono sungunuka m'madzi. Hexabutyridine ili ndi ma stereoisomers, omwe ambiri mwa iwo ndi ma isomers atatu: A, B, ndi C.

 

Ma isomer awa amasiyana m'chilengedwe komanso kagwiritsidwe ntchito. Pakati pawo, mtundu wa A uli ndi kukhazikika kwakukulu kwa kutentha ndi mphamvu zamakina, ndipo nthawi zambiri amagwiritsidwa ntchito ngati chowonjezera cha ma resins a thermosetting, zomatira, zokutira ndi zotetezera. Mtundu wa B ndi C ndi wokhazikika pakatentha kwambiri kuposa mtundu A ndipo ukhoza kugwiritsidwa ntchito ngati zopangira zosungunulira, zosungunulira, ndi utoto.

 

Njira kukonzekera hexabutyldine zambiri utenga zimene tricyandiamide ndi formaldehyde. Chofunikira chake ndikuchepetsa tricandiamide ndi formaldehyde pansi pamikhalidwe yoyenera kuti apange hexabutydine. Ikhoza kukonzedwanso ndi njira zina, monga momwe condensation reaction ya aminocyanamide ndi mankhwala a ketone.

Hexabutyridine ali ndi kawopsedwe, kukhudzana ndi khungu ndi pokoka mpweya kungayambitse mkwiyo, kukhudzana kwa nthawi yayitali ndi kupuma kuyenera kupewedwa. Zida zodzitetezera zoyenerera monga magolovesi, zishango zakumaso, ndi magalasi azivala panthawi yogwira ntchito. Posunga, iyenera kuyikidwa pamalo ozizira, opanda mpweya wabwino, kutali ndi moto ndi okosijeni.
