Tsatanetsatane wa Zamalonda:

Kuwala kwa kuwalandi ukadaulo wodziwika bwino woyeretsa thupi m'mafakitale amakono, ndipoOthandizira Owala Owala(OBAs) amagwira ntchito ngati mankhwala ofunikira kwambiri kuti akwaniritse izi. Mankhwala apadera awa achilengedwe, omwe amatchedwanso kuti fluorescent whitening agents, akhala zowonjezera zofunika kwambiri mu nsalu, kupanga mapepala, sopo, mapulasitiki ndi zokutira, chifukwa cha mawonekedwe awo apadera komanso magwiridwe antchito odalirika.

Mawonekedwe:

1. Ufa wachikasu.
2. Kuunikira thonje, ubweya, silika, ndi zamkati.
3.Muyezo wapamwamba wa zosankha zosiyanasiyana zolongedza.
4. Pepala lowala komanso lolimba, utoto wa thonje.

Ntchito:

Ndi mitundu yosiyanasiyana yomwe ilipo pamsika, zinthu zosiyanasiyana zowunikira kuwala zimapangidwa kuti zigwirizane ndi zinthu zopangira komanso malo opangira. Pakati pawo, Optical Brightener Agent BBU imadziwika ngati chinthu chapadera cha stilbene tetrasulfonic acid, chomwe chimadziwika kwambiri m'mafakitale opanga nsalu ndi mapepala padziko lonse lapansi.

Chimadzitamandira ndi kusungunuka kwabwino kwa madzi: pafupifupi magalamu 150 amatha kusungunuka mu lita imodzi yamadzi ozizira, ndipo kusungunuka kumakwera kufika magalamu 300 pa lita imodzi m'madzi otentha. Kupatula apo, BBU imalekerera kwambiri madzi olimba; ma ayoni a calcium ndi magnesium m'madzi sadzasokoneza magwiridwe antchito ake oyera. Imakhalanso ndi mgwirizano wabwino ndi zinthu zowunikira zodziwika bwino komanso zinthu zochepetsera zomwe zimagwiritsidwa ntchito popanga. Ponena za momwe imagwiritsidwira ntchito, imapereka zotsatira zabwino kwambiri zoyera m'malo okhala ndi pH yoposa 7, pomwe kukana kwake kwa asidi kumakhala kocheperako, kotero sikuvomerezeka pazochitika zokonza asidi kwambiri.
