UV-928 inobata benzotriazole, inokwanisa kutora 270-380 nm ultraviolet chiedza, ine peak absorption rate ye303 nm uye 345 nm. Iyo ine hunhu hwekuenderana kwakanaka, kuderera kuderera, kupararira kwakanaka, kuderera kwekufamba, kugadzikana kwakanaka kwekupisa uye kunyura kwakanyanya, uye inokodzera tembiricha yekurapa system, poda coating uye rolling simbi coating. Yakasanganiswa neyakagadzika mwenje UV292 uye UV123, zvakanyanya kunatsiridza kusimba kwejasi, uye inhibidzira kurasikirwa kwechiedza chekubikira, kurasika, kutsemuka, uye delamination.
Inonyanya kushandiswa mu: mota yekuvhara, coil coil, poda coating.
Yakakurudzirwa huwandu: 1.0-3.0%, iyo chaiyo mari inotemerwa zvinoenderana nemutengi application bvunzo
Yakarongedzwa mu20 kana 25 Kg / katoni.
Chengetedza munzvimbo inotonhorera, yakaoma uye ine mhepo; dzivisa chiedza chezuva chakananga.
Ndapota taura nesu kune chero magwaro ane hukama.
New Venture Enterprise yakatsaurirwa kupa emhando yepamusoro mwenje stabilizer kusangana nezvinodiwa zvakasiyana zvemaindasitiri aya, kutyaira hunyanzvi uye kusimba mukuvandudza zvigadzirwa, ndapota taura nesu:
