Polyurethane Acrylate 7901B: Te "Patu Ārai Katoa" mō ngā Paninga Ahumahi
I roto i te ao mahi-teitei o te hangarau mata, ko te Polyurethane Acrylate 7901B te paearu matua mō ngā paninga whakarewa korehau UV, ngā waituhi UV, me ngā paninga ātete-wiri. Mā tōna tere whakapakeke, tōna pakeke teitei, tōna ātete-pakaru RCA tino pai, tōna ātete-rakuraku, tōna āhuatanga ārai-kōwhai, me tōna pakari taurite, ka whakaratohia he pukupuku kore e kitea ki ngā hua e hono pai ana i te ataahua me te mahi.
Te Whakaora Tere Rawa: He Huringa Whai Hua
I raro i te pānga o te hihi UV, ka oti te hononga hohonu i roto i te 3 hēkona (i te kiato pūngao ≥100mJ/cm²), he mea tino pai mō te paninga hurihuri tere-teitei me ngā raina whakaputa aunoa. Ka whakapai ake i te pai o te whakaputa mā te 40% me te whakaiti i te whakapaunga pūngao wae mā te 25%, inā koa ka whai hua ki ngā whare waea atamai kua whakakikoruatia ki te konganuku korehau me te tānga hua UV 3C nui-rahi.
Te Pakari me te Ātete ki te Mau: Kua Rite mō ngā Wero Tino Nui
He pakari te mata o te 4H (pakari pene) me te ātete kakahu RCA o te ≥300 huringa (175g te kawenga), he nui ake te pai o te 7901B i ngā paninga paerewa. Ka ātete ngāwari ki ngā karawarawa matua me te puehu, ka whakarite kia roa te mau o ngā anga pona me ngā taputapu atamai.
Ātete ki te Rakuraku me te Ārai i te Kōwhai: He Tino Pai i te Wā
Mā te whakamahi i te hangarau ranu inorganic nano-tauine, ka eke ki te pakeke Mohs >3, ka whakarei ake i te ātete ki te rakuraku mā te 50%. Mā ngā whakaū UV synergistic, ka mau tonu te rerekētanga tae ΔE
Te Pūmau Taurite: Te Kaha me te Ngāwari
Mā te modulus rapa e whakahaeretia ana (500-800 MPa), ka whakatauritea te pakeke 3H me te roanga 5% i te whati (ASTM D638), he mea tino pai mō ngā inihi mata takai kua whakakikoruatia ki te korehau me ngā paninga karāhe ātete-wiri o ngā motuka, kia kore ai e pakaru i raro i ngā pānga auau teitei.
Mai i ngā wāhanga whakarewa korehau kanapa ki ngā paninga ātete-kakahu i ngā taiao tino kino, ka tautuhia anō e te 7901B te pono o te paninga ahumahi. Mā tōna mahi tere, mārō, pakari, pumau, me te parakore, ka whakarite kia noho tahi te hangarau me te ataahua i raro i te whakamātautau o te wā.
