Mawu Oyamba
FEMA 3148 ndi organic pawiri ndi mankhwala chilinganizo C12H22O2. Ndi madzi opanda mtundu okhala ndi kukoma kokoma sitiroberi. Zotsatirazi ndizofotokozera zamtundu, kugwiritsa ntchito, kukonzekera ndi chitetezo cha FEMA 3148:
Chilengedwe:
-Maonekedwe: madzi opanda mtundu
-Kulemera kwa mamolekyu: 194.3g/mol
- Malo osungunuka: -57 ° C
- Kutentha kotentha: 217 ° C
-Kuchulukana: 0.88g/cm³
-Kusungunuka: Kusungunuka m'madzi, kusungunuka pang'ono mu mowa
Gwiritsani ntchito:
- FEMA 3148 imagwiritsidwa ntchito kwambiri muzonunkhiritsa ndi zowonjezera zakudya kuti muwonjezere kununkhira kwa sitiroberi, zitsamba ndi zophika.
-Kuonjezera apo, itha kugwiritsidwanso ntchito popanga zinthu zina zakuthupi, monga zosungunulira za Ester, zokutira ndi zowonjezera pulasitiki, etc.
Njira Yokonzekera:
Njira yokonzekera FEMA 3148 nthawi zambiri imatengera izi:
1. Pogwiritsa ntchito adipic acid ngati zopangira, hexanol hexanoate idapangidwa ndi mowa transesterification reaction.
2. Kugonjera kwa caproic acid ester yomwe inapezedwa kuti iwonongeke madzi m'thupi pamaso pa chothandizira champhamvu cha asidi kupanga FEMA 3148.
Zambiri Zachitetezo:
- FEMA 3148 nthawi zambiri imakhala ndi kawopsedwe kakang'ono pakagwiritsidwe ntchito.
-Ndi madzi oyaka, omwe amayenera kusungidwa kutali ndi moto komanso kutentha kwambiri, komanso kusungidwa pamalo ozizira komanso mpweya wabwino.
-Kugwiritsa ntchito kuyenera kupewa kukhudzana ndi khungu ndi maso, monga kukhudza mwangozi, muyenera kutsuka nthawi yomweyo ndi madzi ambiri.
-Pogwiritsa ntchito ndondomekoyi ayenera kulabadira njira zodzitetezera, kuphatikizapo kuvala magolovesi, kuvala zovala zodzitetezera ndi magalasi otetezera. Malo ogwirira ntchito ayenera kutsukidwa bwino ndi kuyeretsedwa pambuyo pa opaleshoniyo.
