E whakaarohia ana e te tini ko te hangarau UV te hangarau "hou ake" mō te whakamaroke i ngā paninga ahumahi. Ahakoa he mea hou pea ki te tini i roto i te umanga paninga ahumahi me te motuka, kua neke atu i te toru tekau tau e whakamahia ana i roto i ētahi atu ahumahi…
E whakaarohia ana te hangarau UV e te tini ko te hangarau "hou ake" mō te whakamaroke i ngā paninga ahumahi. Ahakoa he mea hou pea ki te tini i roto i te umanga paninga ahumahi me te motuka, kua neke atu i te toru tekau tau te roa o tōna whakamahinga i roto i ētahi atu ahumahi. Ka hikoi te tangata i runga i ngā hua papa vinyl pania UV i ia rā, ā, he tokomaha o tātou kei roto i ō tātou kāinga. He mahi nui anō hoki tā te hangarau whakamaroke UV i roto i te umanga hikohiko kaihoko. Hei tauira, mō ngā waea pūkoro, ka whakamahia te hangarau UV ki te paninga o ngā whare kirihou, ngā paninga hei tiaki i ngā hikohiko o roto, ngā wāhanga piri UV, tae noa ki te hanga i ngā mata tae e kitea ana i runga i ētahi waea. Waihoki, ko ngā umanga muka whatu me te DVD/CD e whakamahi ana i ngā paninga UV me ngā piri anake, ā, kāore e noho pēnei i a tātou e mōhiotia ana i ēnei rā me i kore te hangarau UV i āhei i tō rātou whanaketanga.
He aha te whakamaroke UV? Ko te tikanga māmā noa iho, he tukanga hei hono (whakamaroke) i ngā paninga mā te tukanga matū i tīmatahia, i tautokona hoki e te pūngao UV. I roto i te iti iho i te meneti ka huri te paninga mai i te wai ki te totoka. He rerekētanga nui kei roto i ētahi o ngā rauemi mata me te mahi a ngā kapia i roto i te paninga, engari he mārama ēnei ki te kaiwhakamahi paninga.
Ko ngā taputapu tuku iho pēnei i ngā pū rehu hau-atomized, HVLP, pere hurihuri, paninga rere, paninga rōra me ētahi atu taputapu ka pania ngā paninga UV. Heoi, hei utu mō te tuku ki roto i te oumu wera i muri i te paninga me te mura whakarewa, ka whakamaroketia te paninga ki te pūngao UV e whakaputaina ana e ngā pūnaha rama UV kua whakaritea kia whakamārama i te paninga me te iti rawa o te pūngao e hiahiatia ana hei whakamaroke.
Ko ngā kamupene me ngā ahumahi e whakamahi ana i ngā āhuatanga o te hangarau UV kua whakaputa i te uara tino nui mā te whakarato i ngā hua whakaputa tino pai me te hua mutunga tino pai, me te whakapai ake i ngā hua.
Te Whakamahi i ngā Āhuatanga o te UV
He aha ngā āhuatanga matua ka taea te whakamahi? Tuatahi, e ai ki te kōrero i mua ake nei, he tino tere te whakamaroke, ā, ka taea te mahi i te pāmahana rūma. Mā tēnei ka taea te whakamaroke pai o ngā papa e pāngia ana e te wera, ā, ka taea te whakamaroke tere i ngā paninga katoa. Ko te whakamaroke UV te mea nui ki te hua mena he roa te wā whakamaroke (kaki pounamu) i roto i tō tukanga. Waihoki, mā te tere ka taea te tukanga he iti ake te tapuwae. Hei whakataurite, ko te paninga tikanga e hiahia ana kia tunua mō te 30 meneti i te tere raina o te 15 fpm e hiahia ana kia 450 putu te kawe i roto i te oumu, ko te paninga whakamaroke UV e hiahia ana kia 25 putu noa iho (iti iho rānei).
Mā te tauhohenga hononga-UV ka hua ake he paninga he tino pakari te āhua. Ahakoa ka taea te hanga i ngā paninga kia mārō mō ngā mahi pēnei i te papa, ka taea hoki te hanga kia tino ngāwari. E whakamahia ana ngā momo paninga e rua, arā, he mārō, he ngāwari hoki, i roto i ngā mahi motuka.
Ko ēnei āhuatanga ngā pūtake o te whanaketanga tonu me te urunga o te hangarau UV mō ngā paninga motuka. He pono, he wero kei te pā ki te whakamaroke UV o ngā paninga ahumahi. Ko te āwangawanga matua ki te rangatira tukanga ko te kaha ki te whakaatu i ngā wāhi katoa o ngā wāhanga uaua ki te pūngao UV. Me whakaatu te mata katoa o te paninga ki te pūngao UV iti rawa e hiahiatia ana hei whakamaroke i te paninga. Me tātari tupato tēnei i te wāhanga, te whakatakotoranga o ngā wāhanga, me te whakaritenga o ngā rama hei whakakore i ngā wāhi atarangi. Heoi, kua nui ngā whakapainga kua puta i roto i ngā rama, ngā rauemi mata me ngā hua kua hangaia hei wikitoria i te nuinga o ēnei here.
Rama Whakamua o te Motuka
Ko te tono motuhake mō ngā motuka ko te UV te hangarau paerewa kei roto i te umanga rama whakamua o ngā motuka, kua neke atu i te 15 tau te whakamahinga o ngā paninga UV, ā, e 80% o te mākete e whakamahia ana ināianei. E rua ngā wāhanga matua o ngā rama matua me pani — ko te karāhe polycarbonate me te whare whakaata. Me pani te karāhe i tētahi paninga tino mārō, ātete-rakuraku hei tiaki i te polycarbonate mai i ngā āhuatanga me te tukino tinana. He paninga turanga UV (primer) kei te whare whakaata e hiri ana i te papa, ā, e whakarato ana i tētahi mata tino maeneene mō te whakarewa. Ko te mākete paninga turanga whakaata kua 100% te whakamaroke UV. Ko ngā take matua mō te tango ko te hua pai ake, te iti o te tapuwae tukanga me ngā āhuatanga mahi paninga pai ake.
Ahakoa kua whakamaroketia ngā paninga e whakamahia ana ki te hihi UV, kei roto tonu he whakarewa. Heoi, ko te nuinga o te rehu nui ka whakahokia mai, ka hangarua anō ki roto i te tukanga, ā, tata ki te 100% te pai o te whakawhiti. Ko te arotahi mō ngā whanaketanga ā muri ake nei ko te whakanui ake i ngā totoka ki te 100% me te whakakore i te hiahia mō te waikura.
Ngā Wāhanga Kirihou o Waho
Ko tētahi o ngā whakamahinga kāore i te tino mōhiotia ko te whakamahinga o te paninga mārama ka taea te whakaora i te UV ki runga i ngā whakakikorua taha tinana kua whakairohia ki te tae. I te tīmatanga, i whakawhanakehia tēnei paninga hei whakaiti i te kōwhai i te whakaaturanga o waho o ngā whakakikorua taha tinana vinyl. Me tino pakari, me ngāwari hoki te paninga kia mau tonu te piri me te kore e pakaru mai i ngā mea e pā ana ki te whakakikorua. Ko ngā mea e akiaki ana i te whakamahinga o ngā paninga UV i roto i tēnei whakamahinga ko te tere o te whakaora (he iti te tapuwae tukanga) me ngā āhuatanga mahi pai ake.
Ngā Panel Tinana SMC
Ko te rauemi whakakikorua pepa (SMC) he rauemi whakakotahi kua whakamahia hei whakakapi i te maitai mō ngā tau neke atu i te 30. Ko te SMC he kapia polyester kua whakakiia ki te muka karāhe kua makahia hei pepa. Kātahi ka whakanohoia ēnei pepa ki roto i te pokepoke pēhitanga ka hangaia hei panera tinana. Ka taea te whiriwhiri i te SMC nā te mea ka whakaiti i ngā utu taputapu mō ngā oma whakaputa iti, ka whakaiti i te taumaha, ka whakarato i te ātete ki ngā pakaru me te waikura, ā, ka hoatu he wāhi nui ake ki ngā kaihoahoa. Heoi, ko tētahi o ngā wero o te whakamahi i te SMC ko te whakaotinga o te wāhanga i roto i te wheketere huihuinga. He papa porous te SMC. Ina haere te panera tinana, kei runga i te waka ināianei, mā te oumu peita mārama, ka puta he hapa peita e mōhiotia ana ko te "porosity pop". Me whakatika te iti rawa i te wahi, ki te nui rānei ngā "pops", me peita anō te anga tinana.
E toru tau ki muri, i roto i te ngana ki te whakakore i tēnei hapa, i hokohoko a BASF Coatings i tētahi hiri ranu UV/wera. Ko te take i whakamahia ai he rongoā ranu, he mea ka whakamaroketia te rehu nui ki ngā mata kāore i te tino kino. Ko te taahiraa matua ki te whakakore i ngā "pūngao porousity" ko te pānga ki te pūngao UV, ka nui ake te whakanui ake i te mātotoru hononga-whiti o te paninga kua kitea ki ngā mata tino kino. Mena kāore te hiri e whiwhi i te pūngao UV iti rawa, ka eke tonu te paninga ki ngā whakaritenga mahi katoa.
Mā te whakamahi i te hangarau whakaora-rua i tēnei wā ka whakaratohia he āhuatanga paninga hou mā te whakamahi i te whakaora UV, me te whakarato hoki i tētahi āhuatanga haumaru mō te paninga i roto i tētahi tono utu nui. Ehara i te mea ko te hangarau UV anake e whakaatu ana me pēhea te whakarato i ngā āhuatanga paninga ahurei, engari e whakaatu ana hoki he whai hua te pūnaha paninga whakaora-UV ki ngā wāhanga motuka utu nui, nui te rahinga, nui me te uaua. Kua whakamahia tēnei paninga ki runga i te tata ki te kotahi miriona panera tinana.
OEM Clearcoat
Ko te wāhanga mākete hangarau UV e kitea nuitia ana ko ngā paninga o waho o te tinana o ngā motuka, te Class A. I whakaatuhia e te Kamupene Ford Motor te hangarau UV i runga i tētahi tauira waka, te motuka Concept U, i te Whakaaturanga Motuka o Amerika Te Tai Tokerau i te tau 2003. Ko te hangarau paninga i whakaaturia he paninga mārama kua whakamaroketia ki te UV, i hangaia, i tukuna hoki e Akzo Nobel Coatings. I pania, i whakamaroketia hoki tēnei paninga ki runga i ngā panera tinana takitahi i hangaia mai i ngā rauemi rerekē.
I Surcar, te huihuinga nui o te ao mō ngā paninga motuka e tū ana i ia tau rua i Parani, i tukuna e DuPont Performance Coatings me BASF ngā whakaaturanga i te tau 2001 me te 2003 mō te hangarau whakamaroke UV mō ngā paninga mārama motuka. Ko te kaupapa matua o tēnei whanaketanga ko te whakapai ake i tētahi take matua mō te makona o te kiritaki mō te peita—te ātete ki te karawarawa me te paru. Kua whakawhanakehia e ngā kamupene e rua ngā paninga whakamaroke ranu (UV me te wera). Ko te kaupapa o te whai i te ara hangarau ranu ko te whakaiti i te uaua o te pūnaha whakamaroke UV me te whakatutuki i ngā āhuatanga mahi e whaia ana.
Kua tāutahia e DuPont me BASF ngā raina whakamātautau ki ā rāua whare. Kei te raina DuPont i Wuppertal te kaha ki te whakaora i ngā tinana katoa. Ehara i te mea me whakaatu noa e ngā kamupene paninga he mahi paninga pai, engari me whakaatu hoki e rātou he otinga raina peita. Ko tētahi atu painga o te whakaora UV/wera i kōrerotia e DuPont ko te taea te whakaiti i te roa o te wāhanga paninga mārama o te raina whakaoti mā te 50% mā te whakaiti noa i te roa o te oumu wera.
Mai i te taha hangarau, i whakaatu a Dürr System GmbH i tētahi whakaaturanga mō tētahi ariā o tētahi whare hanga mō te whakamaroke UV. Ko tētahi o ngā taurangi matua o ēnei ariā ko te wāhi o te tukanga whakamaroke UV i te rārangi whakaoti. Ko ngā otinga hangarau ko te whakanoho i ngā rama UV i mua, i roto, i muri rānei i te oumu wera. E whakaaro ana a Dürr he otinga hangarau mō te nuinga o ngā kōwhiringa tukanga e uru ana ki ngā whakatakotoranga o nāianei kei te whakawhanakehia. I whakaatu anō hoki a Fusion UV Systems i tētahi taputapu hou — he whakatauira rorohiko o te tukanga whakamaroke UV mō ngā tinana motuka. I mahia tēnei whanaketanga hei tautoko me te whakateretere i te whakamahinga o te hangarau whakamaroke UV i roto i ngā whare hanga.
Ētahi atu Taupānga
Kei te haere tonu ngā mahi whakawhanake mō ngā paninga kirihou e whakamahia ana mō ngā roto o ngā motuka, ngā paninga mō ngā wira koranu me ngā taupoki wira, ngā paninga mārama mō ngā wāhanga nui kua whakairohia ki te tae, me ngā wāhanga o raro i te taupoki. Kei te whakamanahia tonutia te tukanga UV hei tūāpapa whakamaroke pumau. Ko te mea anake e tino rerekē ana ko te neke haere o ngā paninga UV ki ngā wāhanga uaua ake, he nui ake te uara. Kua whakaaturia te pumau me te whai huatanga mō te wā roa o te tukanga me te tono rama whakamua. I tīmata i te neke atu i te 20 tau ki muri, ā, koinei te paerewa ahumahi ināianei.
Ahakoa he mea "pai" te hangarau UV, ko tā te umanga e hiahia ana ki te mahi me tēnei hangarau ko te whakarato i ngā otinga pai rawa atu ki ngā raruraru o ngā kaiwhakaoti. Kāore tetahi e whakamahi i tētahi hangarau mō te hangarau anake. Me whakaputa uara. Ka puta te uara i roto i te ahua o te hua pai ake e pā ana ki te tere o te whakamaroke. Ka puta rānei mai i ngā āhuatanga kua whakapaitia, kua hou rānei kāore i taea e koe te whakatutuki me ngā hangarau o nāianei. Ka puta mai i te kounga tuatahi teitei ake nā te mea he poto ake te wā e tuwhera ana te paninga ki te paru. Tērā pea ka whakaratohia he huarahi hei whakaiti, hei whakakore rānei i te VOC i tō whare. Ka taea e te hangarau te whakaputa uara. Me mahi tahi tonu te umanga UV me ngā kaiwhakaoti ki te hanga otinga hei whakapai ake i te hua o te kaiwhakaoti.
