I roto i te roanga o ā mātou mahi pakihi me ngā kiritaki ahumahi o te ao, he maha ngā pātai kua whakautua e mātou, ā, he maha hoki ngā otinga kua tukuna e mātou e pā ana ki ngā paninga UV-whakaora. Ko ngā pātai e whai ake nei ko ētahi o ngā pātai e tino kitea ana, ā, mā ngā whakautu e haere tahi ana ka āwhina i a koe ki te mārama.
1. He aha ngā paninga ka taea te whakamaroke i te hihi UV?
I roto i te umanga whakaoti rakau, e toru ngā momo matua o ngā paninga ka taea te whakamaroke i te UV.
Ko ngā paninga UV-whakaora 100% kaha (e kiia ana ko te 100% totoka) he hanganga matū wai kāore he whakarewa, he wai rānei. I te paninga, ka tukuna tonutia te paninga ki te pūngao UV me te kore e hiahiatia kia maroke, kia mimiti rānei i mua i te whakamaroke. Ka tauhohe te paninga paninga hei hanga i tētahi paparanga mata totoka mā te tukanga tauhohe kua whakaahuatia, ā, e tika ana te kī ko te photopolymerization. Nā te mea kāore e hiahiatia he mimiti i mua i te whakamaroke, he tino whai hua, he iti hoki te utu o te tukanga tono me te whakamaroke.
Ko ngā paninga UV-whakaora wai, paninga whakarewa rānei, he mārama kei roto he wai, he paninga whakarewa rānei hei whakaiti i te ihirangi hohe (totoka rānei). Mā tēnei whakaiti i te ihirangi totoka ka māmā ake te whakahaere i te matotoru o te kiriata mākū e whakamahia ana, me/ranei te whakahaere i te matotoru o te paninga. I te whakamahinga, ka pania ēnei paninga UV ki ngā mata rakau mā roto i ngā momo tikanga, ā, me whakamaroke rawa i mua i te whakamaroke UV.
He totoka hoki ngā paninga paura ka taea te whakaora i te hihi UV, ā, he tikanga ka pania ki ngā papa hiko mā te kukume hiko. Kia pania, ka whakamahanahia te papa hei whakarewa i te paura, ka rere atu ki waho hei hanga i tētahi kiriata mata. Kātahi ka taea te whakaatu tonu i te papa kua pania ki te pūngao UV hei whakahaere i te whakaora. Kāore e taea te whakarerekē i te āhua o te mata, e kore hoki e tairongo ki te wera.
He momo paninga whakaora-UV kei te wātea, kei roto nei he tikanga whakaora tuarua (whakahohe wera, tauhohe makuku, me ētahi atu) ka taea te whakaora i ngā rohe mata kāore e pāngia e te pūngao UV. E kiia ana ēnei paninga he paninga whakaora-rua.
Ahakoa te momo paninga ka taea te whakamaroke i te hihi UV e whakamahia ana, ka whakaratohia e te whakaotinga mata, te paparanga rānei whakamutunga he kounga tino pai, he pakari me ngā āhuatanga ātete.
2. He pēhea te pai o te piri o ngā paninga UV-whakaora ki ngā momo rakau rerekē, tae atu ki ngā momo rakau hinuhinu?
He tino pai te piri o ngā paninga ka taea te whakamaroke i te hihi UV ki te nuinga o ngā momo rakau. He mea nui kia whakarite kia rawaka ngā āhuatanga whakamaroke hei whakarato i te whakamaroke tika me te piri tika ki te papa.
Tērā ētahi momo rakau he tino hinuhinu, ā, me pania pea he paninga whakatairanga piri, he "tiecoat" rānei. He nui ngā rangahau me ngā whanaketanga a Van Technologies mō te piri o ngā paninga UV-curable ki ēnei momo rakau. Ko ngā whanaketanga hou ko te hiri kotahi UV-curable e ārai ana i te hinu, te wai me te ware pi kei whakararuraru i te piri o te paninga UV-curable.
Heoi anō, ka taea te tango i te hinu kei runga i te mata o te rakau i mua tata tonu o te paninga mā te muru ki te acetone, ki tētahi atu whakarewa tika rānei. Ka whakamakukuhia tuatahitia he kakahu kore-mimiti, mimiti ki te whakarewa, kātahi ka murua ki runga i te mata o te rakau. Ka tukua kia maroke te mata, kātahi ka taea te pani i te paninga UV-whakaora. Mā te tango i te hinu mata me ētahi atu poke ka āwhina i te piri o te paninga ki te mata o te rakau.
3. He aha te momo paru e hototahi ana ki ngā paninga UV?
Ka taea te hiri pai i ngā paru katoa kua whakaahuatia i konei, ā, ka pania ki te paura 100% ka taea te whakaora i te hihi UV, ka taea te whakaora i te hihi UV iti-whakarewa, ka taea te whakaora i te hihi UV i roto i te wai, ka taea rānei te whakaora i te hihi UV. Nō reira, he maha ngā huinga e tika ana hei hanga i te nuinga o ngā paru kei te mākete kia pai mō tētahi paninga ka taea te whakaora i te hihi UV. Heoi anō, he mea nui kia whakaarohia ētahi mea hei whakarite kia hototahi ki te kounga o te mata rakau.
Ngā paru wai me ngā paru ka taea te whakaora i te UV-Wai:Ina pania ngā paninga/panutanga o runga o ngā paru wai, he mea nui kia maroke rawa te paru hei ārai i ngā hapa o te paninga, tae atu ki te kiri karaka, ngā karu ika, te putunga o ngā rua, te putunga me te putunga o ngā wai. Ka puta ēnei hapa nā te iti o te kukū o te mata o ngā paninga e pā ana ki te nui o te kukū o te mata wai e toe ana mai i te paru.
Heoi, ko te paninga o te paninga ka taea te whakamaroke i te wai-UV he mea ngāwari ake. Tērā pea ka kitea he makuku i te tae kua pania, engari kāore he pānga kino ina whakamahia ētahi hiri/paninga o runga ka taea te whakamaroke i te wai-UV. Ka horapa ngāwari te makuku, te wai rānei i toe mai i te paninga o te tae mā roto i te hiri/paninga o runga wai-UV i pania i te wā e whakamaroke ana. Heoi anō, he mea tino taunaki kia whakamātauria tētahi tae me te huinga hiri/paninga o runga ki tētahi tauira whakamātautau e whakaatu ana i mua i te paninga ki te mata e whakaotihia ana.
Ngā paru hinu me ngā paru whakarewa:Ahakoa he pūnaha kei reira ka taea te whakamahi ki ngā paru hinu kāore i tino maroke, ki ngā paru whakarewa rānei, he mea tika tonu, ā, he tino taunaki, kia maroke rawatia ēnei paru i mua i te paninga o tētahi paninga hiri/panu. Ko ngā paru maroke puhoi o ēnei momo, ka roa pea te wā e 24 ki te 48 hāora (neke atu rānei) kia maroke rawatia. Anō, he mea pai kia whakamātauria te pūnaha ki runga i tētahi mata rakau e tika ana.
Ngā paru ka taea te whakaora i te UV 100%:I te nuinga o te wā, he nui te ātete matū me te wai o ngā paninga UV-whakaora 100% ina tino maroke. Nā tēnei ātete ka uaua te piri pai o ngā paninga i muri mai mēnā kāore te mata o raro i te UV-whakaora i horoia kia pai ai te piri ā-ringa. Ahakoa e tukuna ana ngā paru UV-whakaora 100% kua hangaia kia uru ki ngā paninga i muri mai, ko te nuinga o ngā paru UV-whakaora 100% me horoi, me whakaora rānei i te wāhanga (e kiia ana ko te wāhanga "B" te whakaora puku rānei) hei whakatairanga i te piri o te paninga. Ko te wāhanga "B" ka hua ake he wāhi tauhohenga toenga i roto i te paparanga paru ka tauhohe tahi me te paninga UV-whakaora i horoia i te mea ka tukuna ki ngā tikanga whakaora katoa. Ka taea hoki e te wāhanga "B" te horoi ngawari hei whakakore, hei tapahi rānei i tetahi pikinga kakano ka puta mai i te paninga paru. Ka hua ake he piri pai o te paninga i te hiri maeneene, i te paninga o runga rānei.
Ko tētahi atu āwangawanga mō ngā paru ka taea te whakaora i te UV 100% ko ngā tae pouri. He pai ake te mahi a ngā paru he nui te tae (me ngā paninga he nui te tae) ina whakamahia ngā rama UV e tuku ana i te pūngao e tata ana ki te whānuitanga mārama e kitea ana. He kōwhiringa pai rawa atu ngā rama UV tuku iho kua pania ki te gallium me ngā rama mercury paerewa. He pai ake te mahi a ngā rama UV LED e tuku ana i te 395 nm me/ranei te 405 nm me ngā pūnaha he tae ki ngā rarangi 365 nm me te 385 nm. Hei tāpiri, ko ngā pūnaha rama UV e tuku ana i te mana UV nui ake (mW/cm2) me te mātotoru pūngao (mJ/cm2) ka whakatairanga i te whakaora pai ake mā te paninga tae, te paparanga tae rānei kua pania.
Hei whakamutunga, pērā i ngā pūnaha paninga kē atu kua whakahuatia ake nei, he mea pai kia whakamātauria i mua i te mahi ki te mata e pania ana, e whakaotia ana hoki. Kia tino mōhio koe i mua i te whakamaroke!
4. He aha te rahinga kiriata mōrahi/iti rawa mō ngā paninga UV 100%?
Ko ngā paninga paura ka taea te whakaora i te UV he paninga ka taea te whakaora i te UV 100%, ā, ko te matotoru o te paninga ka herea e ngā kaha kukume hiko e herea ana te paura ki te mata e whakaotihia ana. He pai ake te rapu tohutohu i te kaihanga paninga paura UV.
Mō ngā paninga wai ka taea te whakaora i te UV 100%, ko te matotoru o te kiriata mākū i whakamahia ka rite tonu te matotoru o te kiriata maroke i muri i te whakaora UV. Kāore e taea te karo i te whakahekenga engari he iti noa iho te pānga. Heoi anō, he maha ngā tono hangarau e tohu ana i ngā manawanui matotoru kiriata tino kikī, tino whaiti rānei. I roto i ēnei āhuatanga, ka taea te ine tika i te kiriata whakaora hei whakataurite i te matotoru o te kiriata mākū ki te maroke.
Ko te matotoru whakamutunga ka taea te whakatutuki ka whakawhirinaki ki te matū o te paninga UV-curable me te āhua o tōna hanganga. He pūnaha kei te wātea kua hangaia hei whakarato i ngā putunga kiriata tino angiangi i waenga i te 0.2 mil – 0.5 mil (5µ – 15µ) me ētahi atu ka taea te whakarato i te matotoru neke atu i te 0.5 inihi (12 mm). I te nuinga o te wā, ko ngā paninga UV-cured he nui te mātotoru hononga-whiti, pērā i ētahi hanganga urethane acrylate, kāore e taea te matotoru kiriata teitei i roto i te paparanga kotahi kua pania. Ko te nui o te whakahekenga i te wā e whakamarokehia ana ka puta he pakaru nui o te paninga matotoru kua pania. Ka taea tonu te whakatutuki i te matotoru hanga, te matotoru whakaoti rānei mā te whakamahi i ngā paninga UV-curable he nui te mātotoru hononga-whiti mā te pani i ngā paparanga angiangi maha me te kirikiri me/te "B" rānei i waenga i ia paparanga hei whakatairanga i te piri o te paninga.
Ko te tikanga whakaora tauhohe o te nuinga o ngā paninga ka taea te whakaora i te UV ka kiia ko te "whakaoho i ngā rauropi kore utu." Ka taea e tēnei tikanga whakaora tauhohe te pāngia e te hāora i te hau, ka whakaroa, ka aukati rānei i te tere o te whakaora. He maha ngā wā ka kiia tēnei whakaroa ko te aukati hāora, ā, he mea nui rawa atu ina ngana ana ki te whakatutuki i ngā matotoru kiriata tino angiangi. I roto i ngā kiriata angiangi, he teitei ake te horahanga o te mata ki te katoa o te rōrahi o te paninga kua pania ina whakaritea ki ngā matotoru kiriata matotoru. Nō reira, he tino ngāwari ake ngā matotoru kiriata angiangi ki te aukati hāora, ā, he tino puhoi te whakaora. He maha ngā wā, kāore i te tino ora te mata o te whakaotinga, ā, he ahua hinuhinu/hinuhinu. Hei ārai i te aukati hāora, ka taea te tuku i ngā hau kore mahi pērā i te hauota me te hauhā waro ki runga i te mata i te wā whakaora hei tango i te kukū o te hāora, kia taea ai te whakaora tere, kia katoa.
5. Kia pēhea te mārama o tētahi paninga UV mārama?
Ka taea e ngā paninga UV-whakaora 100% te whakaatu i te māramatanga tino pai, ā, ka whakataetae ki ngā paninga mārama pai rawa atu o te umanga. Hei tāpiri, ina pania ki te rakau, ka puta te ataahua me te hohonutanga o te ahua. He mea tino whakamīharo ngā pūnaha urethane acrylate aliphatic he tino mārama, he kore tae hoki ina pania ki te whānuitanga o ngā mata, tae atu ki te rakau. Hei tāpiri, he tino pumau ngā paninga polyurethane acrylate aliphatic, ā, ka ātete ki te hurihanga i te tae ina pakeke haere. He mea nui kia mōhiotia ko ngā paninga iti-kanapa ka marara ake te māramatanga i ngā paninga kanapa, ā, ka iti ake te māramatanga. Heoi, ki te whakataurite ki ētahi atu matū paninga, he rite tonu, ki te kore e pai ake, ngā paninga UV-whakaora 100%.
Ka taea te hanga i ngā paninga ka taea te whakamaroke i te UV e wātea ana i tēnei wā hei whakarato i te māramatanga tino pai, te mahana me te urupare ki te rakau kia rite ki ngā pūnaha whakaotinga tuku iho pai rawa atu. He tino pai te māramatanga, te kanapa, te urupare ki te rakau me ētahi atu āhuatanga mahi o ngā paninga ka taea te whakamaroke i te UV e wātea ana i te mākete i ēnei rā ina tangohia mai i ngā kaihanga kounga.
6. He paninga UV kua tāpirihia he tae, he tae rānei, ka taea te whakaora?
Ae, kei te wātea ngā paninga tae, ngā paninga tae rānei i roto i ngā momo paninga UV-whakaora katoa, engari he mea hei whakaaro māu kia pai ai ngā hua. Ko te mea tuatahi, ko te mea nui ko te mea ka whakararuraru ētahi tae i te kaha o te pūngao UV ki te tuku ki roto, ki te uru rānei ki te paninga UV-whakaora kua pania. Kei te Whakaahua 1 te whakaaturanga o te whānuitanga hikohiko, ā, ka kitea ko te whānuitanga mārama e kitea ana kei te taha tonu o te whānuitanga UV. He rārangi wehewehe te whānuitanga, kāore he rārangi mārama (roa ngaru). Nō reira, ka hanumi haere tētahi rohe ki tētahi rohe tata. I runga i te rohe mārama e kitea ana, kei reira ētahi kereme pūtaiao e kī ana kei waenganui i te 400 nm ki te 780 nm, ko ētahi atu kereme e kī ana kei waenganui i te 350 nm ki te 800 nm. Mō tēnei kōrero, he mea nui kia mōhio tātou ka taea e ētahi tae te aukati i te tuku o ētahi roangaru UV, irahiko rānei.
I te mea ko te arotahi kei te roangaru UV, te rohe irahiko rānei, me tūhuratia taua rohe kia nui ake ngā taipitopito. E whakaatu ana te Whakaahua 2 i te whanaungatanga i waenga i te roangaru o te mārama e kitea ana me te tae e rite ana e whai hua ana ki te aukati i taua mea. He mea nui hoki kia mōhio ko ngā tae he whānuitanga o ngā roangaru, ā, ka horapa pea te tae whero ki tētahi whānuitanga nui, ā, ka mimiti pea ki te rohe UVA. Nō reira, ko ngā tae e tino āwangawanga ana ka horapa ki te whānuitanga kōwhai – karaka – whero, ā, ka taea e ēnei tae te whakararu i te whakaora whai hua.
Ehara i te mea ko ngā tae anake ka whakararuraru i te whakamaroke UV, engari he mea whakaaro anō hoki ina whakamahia ana ngā paninga tae mā, pērā i ngā paninga UV-curable me ngā peita topcoat. Whakaarohia te whānuitanga mimiti o te tae mā titanium dioxide (TiO2), e whakaaturia ana i te Whakaahua 3. He tino kaha te mimiti o te TiO2 puta noa i te rohe UV, heoi anō, ka whakamaroke pai ngā paninga mā, UV-curable. Me pēhea? Kei roto i te whakatakotoranga tupato a te kaiwhakawhanake me te kaihanga paninga te whakautu, me te whakamahi i ngā rama UV tika mō te whakamaroke. Ko ngā rama UV noa e whakamahia ana ka tukuna te pūngao e whakaaturia ana i te Whakaahua 4.
Ko ia rama e whakaaturia ana he mea hanga ki te mercury, engari mā te tāpiri i te mercury ki tētahi atu huānga whakarewa, ka taea te neke te tukunga ki ētahi atu rohe roangaru. Mō ngā paninga TiO2, mā, ka taea te whakaora i te UV, ka āraia pai te pūngao e tukuna ana e te rama mercury paerewa. Ka taea e ētahi o ngā roangaru teitei ake te whakaora engari kāore pea e whai hua te roa o te wā e hiahiatia ana mō te whakaora katoa. Heoi, mā te tāpiri i te gallium ki te rama mercury, he nui te pūngao e whai hua ana i roto i te rohe kāore i āraia pai e te TiO2. Mā te whakamahi i te huinga o ngā momo rama e rua, mā te whakaora (mā te whakamahi i te gallium kua tāpirihia) me te whakaora mata (mā te whakamahi i te mercury paerewa) ka taea te whakatutuki (Whakaahua 5).
Hei whakamutunga, me hanga ngā paninga ka taea te whakaora i ngā hihi UV he tae, he tae rānei, mā te whakamahi i ngā kaiwhakaoho whakaahua tino pai kia tika ai te whakamahinga o te kaha UV – te whānuitanga o te roangaru mārama e tukuna ana e ngā rama – mō te whakaora whai hua.
