Yintoni i-CYASORB UV-3638 CAS 18600-59-4?

I-stabilizer yokukhanya i-3638 inobunzima obuphezulu be-molecular, ukuguquguquka okuphantsi kunye nebala elingenambala.Ngokukodwa kufanelekile kwiimfuno zombala wokuhanjiswa okuphezulu kwishishini le-optical.Ukuzinzisa ukukhanya kwe-3638 kune-stabilizer ephezulu ye-thermal ene-TGA (10%) enkulu kune-371 degrees Celsius.I-stabilizer yokukhanya i-3638 isizukulwana esitsha sokusingqongileyo kunye ne-absorbent ye-ultraviolet esebenzayo.Kwi-UVB, i-UVC inokufunxa okuphezulu.

Isicelo

I-UV-3638 bubunzima obuphezulu bemolekyuli, ukuguquguquka okuphantsi, ungcoliseko olungenambala.Ilungele ngokukodwa imboni ye-optical efuna umbala wokudlulisa, njenge-PET, iilensi ze-PC ezibonakalayo, i-diffuser ekhanyayo ye-backlit liquid crystal display devices, njl. I-Uv-3638 ibonelela ngokufunxa okunamandla kakhulu kunye nokubanzi kwe-UV, ukungcola okungenambala.I-UV-3638 ilungele ipolyester ye-thermoplastic, inayiloni, kunye namashishini okhuselo anobushushu obuphezulu bokusebenza kunye neemfuno ezingqongqo zokufunxa kwe-UV.
