Mawu Oyamba

EGN yofiira yosungunuka ndi mafuta, dzina lathunthu la utoto wosungunuka wamafuta 3B, ndi utoto womwe umasungunuka m'mafuta.

 

Ubwino:

1. Maonekedwe: ufa wofiira mpaka wofiira wofiira.

2. Kusungunuka: kusungunuka mu zosungunulira organic ndi mafuta, osasungunuka m'madzi.

3. Kukhazikika: Kumakhala ndi kuwala kwabwino komanso kukana kutentha, ndipo sikophweka kuwola pansi pa kutentha kwakukulu.

 

Gwiritsani ntchito:

Mafuta osungunuka ofiira EGN amagwiritsidwa ntchito makamaka ngati utoto kapena utoto mu inki zosindikizira, zokutira, mapulasitiki, mphira ndi minda ina yamafakitale. Ili ndi kupepuka kwabwino ndipo imagwiritsidwa ntchito nthawi zambiri pazinthu zakunja, zopangidwa ndi pulasitiki ndi zinthu zina zomwe zimafuna kukana kwa UV.

 

Njira:

EGN yofiira yosungunuka ndi mafuta nthawi zambiri imapezeka mwa kaphatikizidwe. Njira yokonzekerayi imaphatikizapo kusintha kwa condensation pakati pa p-aniline ndi zotumphukira zake ndi utoto wa aniline, ndipo pamapeto pake amapeza EGN yofiira yosungunuka ndi mafuta pambuyo pakusintha koyenera komanso chithandizo chotsatira.

 

Zambiri Zachitetezo:

1. Ofiira osungunuka ndi mafuta EGN ndi utoto wachilengedwe, ndipo chisamaliro chiyenera kutengedwa kuti tipewe kupuma kapena kukhudzana ndi khungu mukamagwiritsa ntchito.

2. Magolovesi otetezera ndi masks ayenera kugwiritsidwa ntchito panthawi ya opaleshoni kuti asayang'ane mwachindunji ndi maso ndi khungu.

3. Iyenera kusungidwa pamalo ozizira, owuma komanso mpweya wabwino, ndipo pewani kukhudzana ndi zinthu zomwe zimayaka moto, okosijeni ndi zinthu zina.

4. Mukapuma kapena kukhudza, sambani malo omwe akhudzidwa mwamsanga ndikupempha thandizo lachipatala.
