7620 Te kapia whakaora-UV i whakamahia ki te whakakikorua hiko korehau UV

**Polyurethane Acrylate 7620 e taea te whakaora whakaahua: Te "Hākakahu Katoa" mō ngā Paninga Tino Pai**

I roto i te ao paninga ahumahi, ko te **polyurethane acrylate 7620 ka taea te whakaahua** he rauemi matua mō ngā tono teitei pēnei i te whakarewa korehau UV, ngā paninga ātete-mau, me ngā waituhi UV, nā ōna **āhuatanga matua e rima: te pakeke o te kiriata, te pakari pai, te ātete mau, te kaha ki te ārai i te kōwhai, me te piri pai**. Ka whakaratohia ki ngā hua he "whakangungu kore e kitea" e whakakotahi ana i te ataahua me te mahi.

**Pakeke Kiriata Teitei, Parenga Āhua Taimana**

I muri i te whakamaroketanga, ka eke te paninga ki te pakeke o te mata o te 4H, neke atu rānei, he rite ki te karāhe hapaira, ā, he ātete pai ki ngā karawarawa o ia rā. Nā tēnei ka waiho hei whiringa pai mō ngā paninga whakaata waea atamai me ngā waitohu whakarewa papai kua whakakorengia ki te korehau, ka puta he mutunga "ātete-pā" kounga teitei.

**Te Tino Kaha, te Pūmau Taurite me te Ngāwari**

Ahakoa tōna tino pakeke, mā te hoahoa mekameka ngota ngota ngāwari ka taea e te paninga te tu atu ki te piko 180° me te kore e pakaru. Nā tēnei putanga hou o te mahi "pakeke engari ngāwari" he mea tino pai mō ngā tono hihiri pēnei i ngā paninga hononga waea atamai takai me ngā mata o roto motuka piko.

**Ātete Paku Pai Rawa, Te Whakahē i te Wā**

Mā te whakamahi i te hangarau nano-crosslinking, ka roa te paninga e mau ana i te neke atu i te 10,000 huringa kakahu (whakamātautau haukū Taber, wira CS-10, kawenga 1kg). He whānuitia te whakamahinga i roto i ngā āhuatanga auau teitei pērā i ngā paninga UV mō ngā papa rakau pakari kounga teitei me ngā mata mataarataki, hei whawhai ki te haukū roa.

**Ārai i te Kōwhai, Tiaki i te Mārama**

Mā te parenga rua ki te hihi UV me te waikura, ka mau tonu te rerekētanga tae ΔE

**Pīpiri Tino Pai, Hototahi Whānui**

I te whiwhinga i te whakatauranga 5B mō ia ASTM D3359 mō ngā konganuku, te karāhe, me ngā kirihou hangarau (hei tauira, PC, ABS), ka piri pūmau te paninga ki ngā papa me te kore he paninga tuatahi. Mā tēnei ka whakatauhia ngā wero wehewehe i roto i ngā paninga whakarewa korehau i runga i ngā āhuahanga uaua.

Mai i ngā whakapaipai kanapa kua whakakikoruatia ki te korehau tae atu ki ngā mata hiko ātete-mau e ahu mai ana i te hangarau, ka tautuhia anō e te polyurethane acrylate ngā paerewa paninga teitei me tōna "pakeke, pakari, pumau, me te parakore," e whakakotahi ana i te ataahua ahumahi me te whaihua pumau.
