Iyo photostabilizer UV770 ndeye yakaderera molecular uremu inodzivirira amine photostabilizer, iyo ine hunhu hwekuenderana kwakanaka, kuderera kuderera, kupararira kwakanaka, kuderera kwekufamba, kugadzikana kwakanaka kwekushisa uye kugadzikana kwepamusoro, uye haitore chiedza chinooneka uye haina kukanganisa ruvara. Kune iyo yakakwirira yepamusoro uye gobvu chikamu cheyakamanikana bhendi, kuumbwa, kune yakanakisa photostability. Iine yakakwira molecular uremu light stabilizer uye ultraviolet absorber, iyo synergistic mhedzisiro yakakosha.
Inonyanya kushanda kune: polyethylene, polypropylene, polystyrene, olefin copolymer, polyester, nyoro polyvinyl chloride, polyurethane, polyformaldehyde uye polyamides, adhesives uye zvisimbiso uye zvichingodaro.
Yakakurudzirwa kuwedzera huwandu: kazhinji 0.05-0.60%. Miedzo yakakodzera ichashandiswa kuona huwandu hwakakodzera hwakawedzerwa mukushandiswa kwacho.
Yakarongedzwa mu25 Kg / katoni. Kana kurongedzwa sezvinodiwa nevatengi.
Chengetedza munzvimbo inotonhorera, yakaoma uye ine mhepo; dzivisa chiedza chezuva chakananga.
Ndapota taura nesu kune chero magwaro ane hukama.
New Venture Enterprise yakazvipira kupa yepamusoro-mhando HALS kusangana nezvinodiwa zvakasiyana zvemaindasitiri aya, kutyaira hunyanzvi uye kusimba mukuvandudza zvigadzirwa, ndapota taura nesu:
