Mawu Oyamba
Pigment yellow 14, yomwe imadziwikanso kuti barium dichromate yellow, ndi mtundu wachikasu wamba. Zotsatirazi ndikuwulula za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha Yellow 14:
Ubwino:
- Maonekedwe: Yellow 14 ndi ufa wachikasu.
- Mapangidwe a Chemical: Ndi inorganic pigment yokhala ndi BaCrO4.
- Kukhalitsa: Yellow 14 imakhala yolimba bwino ndipo sichimakhudzidwa mosavuta ndi kuwala, kutentha ndi zotsatira za mankhwala.
- Zowoneka bwino: Yellow 14 imatha kuyamwa kuwala kwa ultraviolet ndi blue-violet, kuwonetsa kuwala kwachikasu.
Gwiritsani ntchito:
- Yellow 14 imagwiritsidwa ntchito kwambiri pakupaka, utoto, mapulasitiki, mphira, zoumba ndi mafakitale ena kuti apereke mawonekedwe achikasu.
- Amagwiritsidwanso ntchito kwambiri pazaluso ndi kujambula ngati chithandizo chamitundu.
Njira:
- Kukonzekera kwa yellow 14 nthawi zambiri kumapezeka pochita barium dichromate ndi mchere wofanana wa barium. Masitepe enieni amaphatikizapo kusakaniza ziwirizi, kuzitenthetsa kutentha kwambiri ndi kuzisunga kwa nthawi ndithu, kenako kuziziziritsa ndi kuzisefa kuti zipange mpweya wachikasu, ndipo potsirizira pake kuumitsa.
Zambiri Zachitetezo:
- Yellow 14 ndi mtundu wotetezeka, komabe pali njira zina zodzitetezera zomwe muyenera kuzidziwa:
- Pewani kutulutsa mpweya kapena kukhudzana ndi ufa wachikasu 14 kuti mupewe kupsa mtima kwa kupuma ndi khungu.
