He aha ka CYASORB UV-3638 CAS 18600-59-4?

He kaumaha molekala kiʻekiʻe ka mea hoʻopaʻa kukui 3638, haʻahaʻa ka volatility a me ka ʻili kala ʻole. Kūpono loa no nā koi kala transmittance kiʻekiʻe o ka ʻoihana optical. Loaʻa i ka mea hoʻopaʻa kukui 3638 kahi mea hoʻopaʻa wela kiʻekiʻe me kahi TGA (10%) ʻoi aku ma mua o 371 degere Celsius. ʻO ka mea hoʻopaʻa kukui 3638 kahi hanauna hou o ka mea hoʻomoʻa ultraviolet aloha i ke kaiapuni a me ka pono. No UVB, loaʻa iā UVC ka hoʻomoʻa pono kiʻekiʻe.

Noi

He kaumaha molekala kiʻekiʻe ʻo UV-3638, haʻahaʻa ka volatility, haumia kala ʻole. He kūpono loa ia no ka ʻoihana optical e pono ai ke kala transmittance, e like me PET, nā aniani mea optical PC, ka mea hoʻolaha kukui o nā mea hōʻike kristal wai backlit, a pēlā aku. Hāʻawi ʻo Uv-3638 i ka omo UV ikaika a ākea, haumia kala ʻole. He kūpono ka UV-3638 no nā ʻoihana thermoplastic polyester, nylon, a me nā pale me nā mahana hana kiʻekiʻe a me nā koi koʻikoʻi no ka omo UV.
