Mawu Oyamba

Yellow 181 ndi organic pigment yokhala ndi dzina lamankhwala la phenoxymethyloxyphenylazolizoyl barium.

 

Yellow 181 pigment ili ndi mtundu wachikasu wonyezimira ndipo imakhala yokhazikika komanso yokhazikika. Imalimbana kwambiri ndi zosungunulira ndi kuwala, ndipo simakonda kuzirala ndi kuzimiririka. Yellow 181 imakhalanso ndi kutentha kwabwino komanso kukana mankhwala.

 

Yellow 181 imagwiritsidwa ntchito kwambiri ngati utoto m'mafakitale monga inki, mapulasitiki, zokutira, ndi mphira. Mtundu wake wachikasu wowoneka bwino umawonjezera kukopa ndi kukongola kwa mankhwalawa. Yellow 181 imagwiritsidwanso ntchito kwambiri popaka utoto, zojambulajambula ndi kusindikiza.

 

Kukonzekera kwa Huang 181 nthawi zambiri kumapangidwa ndi njira zopangira mankhwala. Makamaka, phenoxymethyloxyphenyl triazole imapangidwa koyamba, kenako imakhudzidwa ndi barium chloride kupanga utoto wachikasu 181.

Pewani kutulutsa fumbi lachikasu 181, ndipo pewani kuyang'ana pakhungu ndi maso. Posunga ndi kusamalira Yellow 181, malamulo amderalo akuyenera kutsatiridwa, ndipo akuyenera kusungidwa pamalo owuma, opanda mpweya wabwino. Mukameza mwangozi kapena kukhudzana ndi Huang 181, muyenera kupita kuchipatala mwachangu.
