UV326 ndeye UV inopinza ye300-400nm, ine yakanaka mwenje kudzikamisa mhedzisiro, inoshandura ultraviolet mwenje kuita kupisa simba kuburikidza nephotochemical chiito; chigadzirwa chacho chinowedzera kunyura kwebhendi refu, kuenderana kwakanaka ne polyolefin, kuderera kwemhepo uye kuvharidzira phenol ionization; chigadzirwa chine kunaka kwe alkaline uye hachizokonzeri kuchinja kwemavara nekuda kwesimbi. Nekuda kweiyo yakakwira ionization inogara, simbi yekuomesa mumiriri, inokonzeresa pane yayo yakaderera pesvedzero; mune zvigadzirwa zvekunze, zvinogona kushandiswa ne phenolic antioxidant uye phosphite antioxidant.
Inonyanya kushandiswa mu polyvinyl chloride, polystyrene, unsaturated resin, polycarbonate, polymethyl methacrylate, polyethylene, ABS resin, epoxy resin uye zvichingodaro.
Yakakurudzirwa huwandu: 0.1% -1.0%, 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:
