Shandisa:
- FEMA 3148 inowanzoshandiswa muzvinonhuwira uye zvinowedzerwa zvekudya kuwedzera sitirobheri, herbal uye kubheka kunaka.
-Kuwedzera, inogona zvakare kushandiswa kugadzira mamwe ma organic compounds, akadai seEster solvents, coatings uye epurasitiki additives, nezvimwe.
Kugadzirira nzira:
Nzira yekugadzirira yeFEMA 3148 kazhinji inotora matanho anotevera:
1. Ichishandisa adipic acid seyakagadzirwa, hexanol hexanoate yakagadzirwa nedoro transesterification reaction.
2. Kuzviisa pasi peiyo yakawanikwa caproic acid ester kune dehydration condensation reaction pamberi peiyo yakasimba acid catalyst kugadzira FEMA 3148.
Zvekuchengetedza
- FEMA 3148 kazhinji ine yakaderera chepfu pasi peyakajairika mamiriro ekushandiswa.
-Imvura inopfuta, inofanira kuchengetedzwa kure nemoto uye kupisa kwakanyanya, uye inochengetwa munzvimbo inotonhorera, inofefetera zvakanaka.
-kushandiswa kunofanira kudzivisa kusangana neganda nemaziso, zvakadai sekusangana netsaona, inofanira kubva yasuka nemvura yakawanda.
-mukushandiswa kwekugadzirisa kunofanira kubhadhara matanho ekudzivirira, kusanganisira kupfeka magirafu, kupfeka zvipfeko zvakakodzera zvekudzivirira uye magirazi ekudzivirira. Nzvimbo yebasa inofanira kunyatsocheneswa uye kucheneswa mushure mekushanda.
