Choyamwa UV UV-366 CAS NO.: 169198-72-5
Dzina la mankhwala: 2 – (2′-hydroxy-4′-benzoic acid phenyl) -5 chloro-2H-benzotriazole
Fomula ya maselo:
Kulemera kwa maselo:365.77
CAS NO.: 169198-72-5
Kapangidwe ka mankhwala: C19H12ClN3O3
Chizindikiro chaukadaulo:
Mawonekedwe: Olimba, pafupifupi oyera
Zomwe Zili Mu Assay: ≥98.5 % (HPLC)
Malo osungunuka: 183.1-184.5 C
Phulusa: ≤ 0.5%
Gwiritsani ntchito: Ili ndi kulemera kwakukulu kwa mamolekyulu, siisinthasintha, imakana kutulutsa; imapangidwa mosavuta.
Choyamwa cha UV cha benzotriazole chomwe chingalepheretse kuwonongeka kwa okosijeni, kuteteza ulusi, ndikukweza mtundu wa zinthu zopangidwa ndi nsalu; uwu ndi mbadwo watsopano wa zoyamwa za UV zokhala ndi ukadaulo wovomerezeka ndipo zidapambana satifiketi yazinthu zofunika kwambiri m'boma mu 2007, zafika pamlingo wapadziko lonse lapansi.
Ubwino: Mankhwala othandiza oletsa UV, okhala ndi UV molar extinction coefficient yochulukitsa nthawi 2.6 kuposa ya benzophenone UV absorbers, ndi nthawi 1.8 kuposa ya benzotriazole (yomwe imalowa m'malo mwa alkylphenol derivatives) ya UV absorbers.
Kuyamwa kwamphamvu, makamaka ulusi; kuyamwa kwa microfiber ndi kwamphamvu kuposa kwa triazine ultraviolet absorber.
Kulongedza ndi Kusunga:
Phukusi: 25KG/BOTANI
Kusungirako: Kokhazikika m'nyumba, kusunga mpweya wabwino komanso kutali ndi madzi ndi kutentha kwambiri.
