WOTETEZA WA POLYMER: UV ABSORBER.

Mapangidwe a maselo aUV absorbersNthawi zambiri imakhala ndi zomangira ziwiri zolumikizana kapena mphete zonunkhiritsa, zomwe zimatha kuyamwa cheza cha ultraviolet cha kutalika kwake (makamaka UVA ndi UVB).

Pamene kuwala kwa ultraviolet kumayatsa mamolekyu omwe amayamwa, ma elekitironi omwe ali mu mamolekyu amasintha kuchoka pansi kupita kumalo osangalatsa, kutengera mphamvu ya cheza cha ultraviolet.

Pambuyo poyamwa kuwala kwa ultraviolet, molekyu imakhala mumkhalidwe wokondwa ndi mphamvu zambiri. Kuti abwerere ku nthaka yokhazikika, mamolekyu amadzimadzi amamasula mphamvu m'njira zotsatirazi:
① Kusintha kopanda ma radiation: sinthani mphamvu kukhala mphamvu ya kutentha ndikuyimasula kumalo ozungulira.
②Fluorescence kapena phosphorescence: gawo la mphamvu limatha kutulutsidwa ngati kuwala kowoneka (kawirikawiri).

Mwa kuyamwa cheza cha ultraviolet ndikusandutsa mphamvu ya kutentha, zotsekemera za UV zimachepetsa kuwonongeka kwachindunji kwa cheza cha ultraviolet ku zinthu (monga mapulasitiki, zokutira) kapena khungu.
Pazinthu zoteteza ku dzuwa, zotsekemera za UV zimatha kuteteza kuwala kwa UV kuti zisalowe pakhungu ndikuchepetsa chiopsezo cha kupsa ndi dzuwa, kujambula zithunzi ndi khansa yapakhungu.

Zoyezera zathu za UV ndizoyenera ma polima, zokutira ndi zodzola. Ngati mukufuna zinthu, chonde omasuka kulankhula nafe, tidzayankha pasanathe maola 48.
