Hangarau Whakaora UV

1. He aha te Hangarau Whakamaroke UV?

Ko te Hangarau Whakamaroke UV he hangarau whakamaroke tere, whakamaroke rānei i roto i ngā hēkona, e whakamahia ai te hihi ultraviolet ki ngā kapia pērā i ngā paninga, ngā piripiri, te waituhi tohu me ngā ātete-whakaahua, me ētahi atu, hei whakaputa i te whakapūtātanga whakaahua. Mēnā he tikanga tauhohenga whakapūtātanga mā te whakamaroke wera, te whakaranu rānei i ngā wai e rua, he maha ngā hēkona ki te maha o ngā hāora ka maroke te kapia.

E 40 tau ki muri, i whakamahia tuatahitia tēnei hangarau mō te whakamaroke i te tānga ki runga i te papa rakau mō ngā rauemi hanga whare. Mai i taua wā, kua whakamahia ki ngā mara motuhake.

Nō nā tata nei, kua tino pai ake te mahi a te kapia whakaora UV. Heoi anō, kei te wātea inaianei ngā momo kapia whakaora UV, ā, kei te tere tipu haere te whakamahinga me te mākete, nā te mea he painga mō te penapena pūngao/wāhi, te whakaiti i te para, me te whakatutuki i te hua nui me te maimoatanga pāmahana iti.

Hei tāpiritanga, he pai hoki te hihi UV mō te hanga whatu nā te mea he nui tōna kiato pūngao, ā, ka taea e ia te arotahi ki ngā diameter iti rawa o te ira, e āwhina ana ki te whiwhi hua hanga tino tika.

I te mea ehara i te whakarewa, kāore he whakarewa rauropi o te kapia whakaora UV e puta ai ngā pānga kino ki te taiao (hei tauira, te parahanga o te hau). Heoi anō, nā te mea he iti ake te pūngao e hiahiatia ana mō te whakaora, ā, he iti ake te tukunga o te hauhā, ka whakaitihia e tēnei hangarau te taumahatanga taiao.

2. Ngā Āhuatanga o te Whakaora UV

1. Ka puta te tauhohenga whakamaroke i roto i ngā hēkona

I roto i te tauhohenga whakamaroke, ka huri te monomer (Wai) hei polymer (Toka) i roto i ētahi hēkona ruarua.

2. Te aro nui ki te taiao

I te mea ka whakamaroketia te rauemi katoa mā te photopolymerization kore-whakarewa, he tino whai hua ki te whakatutuki i ngā whakaritenga o ngā ture me ngā whakahau e pā ana ki te taiao pērā i te Ture PRTR (Pollutant Release and Transfer Register) ISO 14000 rānei.

3. He tino pai mō te aunoatanga tukanga

Kāore te rauemi e taea te whakaora i te hihi UV e maroke mena kāore i te kitea ki te mārama, ā, kāore i rite ki te rauemi e taea te whakaora i te wera, kāore e maroke haere i te wā e tiakina ana. Nō reira, he poto te roa o tōna ora i roto i te kohua hei whakamahi i roto i te tukanga aunoa.

4. Ka taea te maimoatanga pāmahana-iti

Nā te poto o te wā tukatuka, ka taea te whakahaere i te pikinga o te pāmahana o te mea e hiahiatia ana. Koinei tētahi o ngā take e whakamahia ai i roto i te nuinga o ngā taputapu hiko e aro ana ki te wera.

5. He pai mō ngā momo tono katoa nā te mea he maha ngā rauemi e wātea ana

He tino pakari, he kanapa hoki te mata o ēnei rauemi. Heoi anō, he maha ngā tae e wātea ana, ā, ka taea te whakamahi mō ngā momo kaupapa.

3. Te Mātāpono o te Hangarau Whakaora UV

Ko te tukanga o te huri i te monomer (wai) hei polymer (totoka) mā te āwhina o te UV ka kiia ko te UV Curing E, ā, ko te rauemi waro hangai hei whakaora ka kiia ko te UV Curable Resin E.

Ko te Resin UV Curable he matū e titoa ana i:

(a) monomer, (b) oligomer, (c) kaiwhakaoho photopolymerization me (d) ngā momo tāpiri (ngā mea whakau, ngā mea whakakī, ngā tae, me ētahi atu).

(a) Ko te Monomer he rauemi rauropi kua whakapūhuitia, ā, kua hurihia hei ngota polymer nui ake hei hanga kirihou. (b) Ko te Oligomer he rauemi kua tauhohe kē ki ngā monomer. Pērā i te monomer, ka whakapūhuitia te oligomer, ā, ka hurihia hei ngota nui hei hanga kirihou. Kāore e ngāwari te whakaputa i te tauhohenga polymerization e te Monomer, e te oligomer rānei, nō reira ka honoa rāua ki te kaiwhakaoho photopolymerization hei tīmata i te tauhohenga. (c) Ka whakaohokia te kaiwhakaoho photopolymerization e te mimiti o te mārama, ā, ina puta ngā tauhohenga, pēnei i ēnei e whai ake nei:

(b) (1) Te tapahi, (2) Te tango hauwai, me (3) Te whakawhiti irahiko.

(c) Mā tēnei tauhohenga, ka puta ngā matū pēnei i ngā ngota rauropi, ngā katote hauwai, me ētahi atu, e tīmata ana i te tauhohenga. Ka whakaekea e ngā ngota rauropi kua puta, ngā katote hauwai, me ētahi atu, ngā ngota oligomer, ngā ngota monomer rānei, ā, ka puta he tauhohenga polymerization toru-ahu, he tauhohenga hononga whakawhiti rānei. Nā tēnei tauhohenga, ki te hangaia ngā ngota he nui ake te rahi i te rahi kua tohua, ka huri ngā ngota e pāngia ana e te UV mai i te wai ki te totoka. (d) Ka tāpirihia ngā momo tāpiri (whakaū, whakakī, tae, me ētahi atu) ki te hanganga kapia UV ka taea te whakaora e hiahiatia ana, hei

(d) hoatu he pumau, he kaha, me ētahi atu.

(e) Ko te kapia UV-āhua-wai, he ka taea te whakaora, he rere noa, ka whakamaroketia mā ngā mahi e whai ake nei:

(f) (1) Ka mimitihia e ngā kaiwhakaoho photopolymerization te UV.

(g) (2) Ka whakaohokia ēnei kaiwhakaoho photopolymerization kua mimiti i te UV.

(h) (3) Ka tauhohe ngā kaiwhakaoho photopolymerization kua whakahohehia ki ngā wāhanga kapia pēnei i te oligomer, te monomer, me ētahi atu, mā te pirau.

(i) (4) Hei tāpiri, ka tauhohe ēnei hua ki ngā wāhanga kapia, ā, ka puta he tauhohenga mekameka. Kātahi ka puta te tauhohenga hononga-toru-ahu, ka piki ake te taumaha ngota, ā, ka whakamarokehia te kapia.

(j) 4. He aha te UV?

(k) He ngaru hikohiko te UV, he 100 ki te 380nm te roangaru, he roa ake i te roangaru o ngā hihi-X engari he poto ake i te roangaru o ngā hihi e kitea ana.

(l) E toru ngā wāhanga o te hihi UV e whakaaturia ana i raro nei, e ai ki tōna roangaru:

(m) UV-A (315-380nm)

(n) UV-B (280-315nm)

(o) UV-C (100-280nm)

(p) Ina whakamahia te UV hei whakamaroke i te kapia, ka whakamahia ngā waeine e whai ake nei hei ine i te nui o te hihi UV:

(q) - Te kaha o te hihi (mW/cm2)

(r) Te kaha o te hihi mō ia wāhanga horahanga

(s) - Te pānga o te UV (mJ/ cm2)

(t) Te pūngao hihi mō ia wāhanga horahanga me te tapeke o ngā photon hei tae atu ki te mata. Te hua o te kaha hihi me te wā.

(u) - Te whanaungatanga i waenga i te pānga o te hihi UV me te kaha o te hihi

(v) E=I x T

(w) E=Te pānga o te UV (mJ/cm2)

(x) I = Te Kaha (mW/cm2)

(y) T=Te wā irahiko (s)

(z) I te mea ko te pānga o te hihi UV e hiahiatia ana mō te whakamaroke ka whakawhirinaki ki te rauemi, ka taea te whiwhi i te wā whakamahana e hiahiatia ana mā te whakamahi i te tātai i runga ake nei mēnā e mōhio ana koe ki te kaha o te whakamahana UV.
