Madera omwe ali pafupi ndi equator kapena m'malo okwera kwambiri amakhala ndi mphamvu ya ultraviolet. Kukhudzidwa ndi ultraviolet kwa nthawi yayitali kungayambitse mavuto monga kutentha ndi dzuwa komanso kukalamba kwa khungu, kotero chitetezo cha dzuwa n'chofunika kwambiri. Mafuta oteteza ku dzuwa amapezeka makamaka kudzera mu njira yophimbira thupi kapena kuyamwa mankhwala.

Izi ndi zosakaniza zingapo zodziwika bwino zomwe zimagwiritsidwa ntchito popanga mafuta oteteza ku dzuwa.

① Nambala yocheperako imatanthauza kuti chosakaniza ichi ndi chotetezeka kwambiri.

Kapangidwe ka mankhwala oteteza ku dzuwa ndi kuyamwa ndi kusintha. Mankhwala achilengedwe omwe amapezeka mu mankhwala oteteza ku dzuwa amatha kuyamwa mphamvu ya kuwala kwa ultraviolet ndikusandutsa mphamvu yotentha kapena kuwala kopanda vuto. Kachitidwe kameneka kamafunika kuti khungu lizigwirizana ndi mankhwala enaake, kotero zinthu zina zoteteza ku dzuwa zimatha kuyambitsa kuyabwa kapena ziwengo pakhungu. Komabe, mankhwala oteteza ku dzuwa nthawi zambiri amakhala okhazikika komanso olowa bwino, ndikupanga filimu yoteteza yofanana komanso yolimba pamwamba pa khungu, zomwe zimapangitsa kuti dzuwa likhale lotetezeka bwino.

Kampani yathu imapereka zinthu zosiyanasiyana zoyamwitsa UV za matenda a khungu/zosamalira khungu/zodzola, zomwe zimagwirizana ndi miyezo yambiri yokongoletsa ndi mankhwala. Mudzalandira yankho mkati mwa maola 48 mutafunsa.
