I-Absorption ye-UV-UV-928 iyi-benzotriazole UV absorber, ekwazi ukumunca ukukhanya kwe-ultraviolet okungu-270-380 nm, ngenani eliphakeme lokumunca elingu-303 nm no-345 nm. Inezici zokuhambisana okuhle, ukuguquguquka okuphansi, ukuhlakazeka okuhle, ukuhamba okuphansi, ukuzinza okuhle kokushisa kanye nokusebenza kahle kokumuncwa okuphezulu, futhi ifaneleka ohlelweni lokuphulukisa lokushisa okuphezulu, ukumbozwa kwe-powder kanye ne-rolling steel coating. Ihlanganiswe nesiqinisi sokukhanya i-UV292 ne-UV123, ithuthukisa ngokuphawulekayo ukuqina kwento enamathelayo, futhi ivimbele ukulahleka kokukhanya okunamathelayo, ukuguquguquka kombala, ukuqhekeka, kanye ne-delamination.
Ikakhulukazi esetshenziswa: enamathela yezimoto, ikhoyili enamathela, powder enamathela.
Inani elinconyiwe: 1.0-3.0%, inani elithile linqunywa ngokuya ngokuhlolwa kwesicelo sekhasimende
Ipakishwe ku-20 noma 25 Kg / ibhokisi.
Gcina endaweni epholile, eyomile futhi engenawo umoya; gwema ukukhanya kwelanga okuqondile.
Sicela usithinte nganoma yimaphi amadokhumenti ahlobene.
I-New Venture Enterprise izinikele ekuhlinzekeni iziqinisi zokukhanya ezisezingeni eliphezulu ukuze kuhlangatshezwane nezidingo ezahlukahlukene zalezi zimboni, ukushayela ubuhlakani obusha nokuzinza ekuthuthukisweni komkhiqizo, sicela usithinte:
