Tambayoyin da ake yawan yi
Tambaya: Shin fata na PVC baƙar fata ya fi zafi fiye da PVC mai launin ruwan kasa?
A: iya. Baki PVC yana amfani da Carbon Black pigments tare da <5% IR tunani, kai har zuwa digiri 78 a ƙarƙashin nauyin hasken rana kai tsaye. Brown PVC yana amfani da Iron Oxide, yana nuna har zuwa 15% na radiation IR da rage girman yanayin zafi da kusan digiri 8.
Tambaya: Wane launi na fata na roba ya fi tsayi a cikin hasken rana?
A: Black PVC yawanci yana nuna kwanciyar hankali UV mafi girma. Carbon Black pigment a zahiri yana toshe hotunan UV daga wulakanta matrix polymer, yana hana hauka sama don> awanni 800 a ƙarƙashin gwajin ASTM G154, yayin da launin ruwan kasa yana buƙatar ƙarin matakan sinadarai (HALS) don hana faɗuwa.
