Mapepa ePC (polycarbonate) ari pasi pekuchembera nekuda kwemwaranzi yeultraviolet, saka vagadziri vemapepa ePC vakatora nzira dzakasiyana dzekugadzirisa dambudziko iri kuti vawedzere hupenyu hwesevhisi.Parizvino, iyo inonyanya kushanda uye inoshanda nzira ndeyekuwedzera ultraviolet absorbers (yakapfupikiswa se UV zvinhu) kune chigadzirwa.Zvinoenderana neakasiyana maitiro ekugadzira, kune nzira nhatu dzekuwedzera UV zvinhu: yakasanganiswa yekuwedzera nzira, yekubikira nzira uye co-extrusion nzira.
1.Mixed yekuwedzera nzira
Chimwe chikamu cheUV zvinhu (inenge 5%) inosanganiswa muPC zvinhu, uye yobva yanyungudutswa uye kuburitswa pakupisa kwakanyanya.Zvisinei, mahwendefa akawanda anogadziriswa nenzira iyi achiri kutarisana nezuva, saka kuchembera kweplate yepamusoro kuchiri kudziviswa.
2.Coating nzira
Pfeka dhizaini yeUV zvinhu pamusoro pebhodhi.Nekudaro, nekuda kwekusawirirana kwakashata kwePC uye zvimwe zvinhu, mvura inonaya inogona kugeza zviri nyore kuvhara pamusoro pebhodhi mushure mekuiswa.Mukuwedzera, tichifunga kuti bhodhi inogona kukuvadzwa panguva yekuchengetedza uye kutakura, mativi ose ebhodhi akafukidzwa nefirimu inodzivirira panguva yekugadzirwa.Iyo firimu yekudzivirira inofanirwa kubvarurwa mushure mekuiswa, uye nekuti iyo inodzivirira firimu inonamira, yakawanda yakawanda yeUV zvinhu zvakaputirwa pamusoro inonamatira panguva yekubvarura, saka mhedzisiro yacho haina kusimba.
3.Coextrusion
Parizvino, nzira yepamusoro-soro munyika ndeye co-extrusion nzira.Nenzira iyi, iyo PC main material uye UV zvinhu zvinonyungudutswa uye zvakanyungudutswa pakupisa kwepamusoro mune extruder, yakabatanidzwa muforoma, yobva yadonhedzwa nemumhanyi muforoma kuti igadzire dense yekudzivirira pamusoro pePC.Nekudaro, shanduko yetembiricha, kumhanya, kudzvanywa, nezvimwewo mukugadzirwa chaiko uchishandisa nzira iyi kuchakanganisa kugoverwa kwezvinhu zveUV pamusoro pepepa, zvichiita kuti ukobvu husaenzana pahupamhi hwepepa.
