Yintoni iCYASORB UV-3638 CAS 18600-59-4?

Isiqinisi sokukhanya i-3638 sinobunzima obuphezulu beemolekyuli, sinokuguquguquka okuphantsi kwaye asinambala. Sifanelekile ngokukodwa kwiimfuno eziphezulu zombala wokuhambisa kwishishini le-optical. Isiqinisi sokukhanya i-3638 sinesiqinisi sobushushu esiphezulu esine-TGA(10%) engaphezulu kwama-371 degrees Celsius. Isiqinisi sokukhanya i-3638 sisizukulwana esitsha se-ultraviolet absorber enobuhlobo nokusingqongileyo nesebenzayo. Kwi-UVB, i-UVC inokusetyenziswa okuphezulu kokusetyenziswa.

Isicelo

I-UV-3638 inobunzima obuphezulu beemolekyuli, ayiguquguquki kakhulu, ayinambala. Ifanelekile ngokukodwa kwishishini le-optical elifuna umbala wokudlulisa, njenge-PET, iilensi zezinto ezibonakalayo zePC, i-diffuser yokukhanya yezixhobo ze-backlit liquid crystal display, njl. I-UV-3638 inika ukufunxwa kwe-UV okunamandla kakhulu nokubanzi, ungcoliseko olungenambala. I-UV-3638 ifanelekile kwi-thermoplastic polyester, i-nylon, kunye namashishini okhuselo aneqondo lobushushu eliphezulu lokucubungula kunye neemfuno ezingqongqo zokufunxwa kwe-UV.
