ngā purongo

I raro i te ia o ngā mata hau nui me ngā mata hau o waho, ko te pumau, te kaha me te urutau tukanga o terauemi whakahiatoKa whakatau tika te pūnaha i te roa o te mata me te whai huatanga o te whakaputa hiko. Hei papa whakakaha matua mō te anga mata, te tukutuku, te taha ārahi, te taha muri me ētahi atu wāhanga, kua noho te muka karāhe tapatapahi hei rauemi paerewa mō te whakahekenga korehau VARTM, te whakapiri/whakairo ā-ringa me te ōritetanga pai, te urunga tere, te kaha ki te whakairo, me te here kaha i waenga i ngā paparanga. Ki te whiriwhiri i te tauira me te taumaha hē, ka arahi te mama ki ngā hapa mata me te kore o te kāpia i roto i te whakahekenga, ā, ka pā te taumaha ki te kaha hanganga me te mahi ngenge. Ka arotakehia e tēnei pepa te tauira paerewa, ngā whakatakotoranga matua, te arorau kōwhiringa, me te taurite tono o te muka tapatapahi mō ngā mata hau.

1. He mea tapatapahi mō ngā mata hau: te tūnga taketake me ngā whakaritenga matua

-Te rerekētanga kounga mō ia wāhanga horahanga: ±5%

-Te nui o te makuku: ≤0.2%

-Kaha kume: ≥30–180N/5cm (ka piki ake me te taumaha karamu)

-Te uruhanga: tere te rumaki, iti ngā mirumiru hau, he pai mō te rere o te wai korehau

-Ātete ki te huarere/ātete ki te rehu tote: me whakapakari ake ngā tauira takutai moana i te urutaunga ārai-waikura

-Te pumau: kāore e ngaro te paura, kāore e whakarārangihia, kāore he huruhuru, he pai mō te whakarārangi aunoa

muka karāhe tapatapahiKo te nuinga o te wā, ka mahi i ngā mahi whakakaha tautoko kore-matua, te whakataurite i te mata, te whakawhiti i waenga i ngā paparanga, me te ātete ki te whakarerekētanga o te mata. Ka whakamahia ngātahitia me te kakahu kotahi-ara, te kakahu maha-tuaka, te whatu whatu tonu, me te whatu whatu mata hei hanga i tētahi paparanga hanganga katoa.

2. Rārangi tauira me ngā whakaritenga o te mata huruhuru tapatapahi o te hau

Ko ngā tauira matua o te umanga ko te EMC (emulsion)/CMC (paura), ā, ko te whānui e whakamahia whānuitia ana ko te 1250/1040/2500mm. Ko ngā tauira e whai ake nei e whakamahia whānuitia ana mō te hanga papatipu mata.：

1) E rite ana te tauira paerewa ki te taumaha karamu

-EMC225: 225g/㎡, paparanga whakawhiti angiangi, mata maeneene

-EMC300: 300g/㎡, kaha matua whānui, anga/whatunga whānui

-EMC450: 450g/㎡, whakapakari matotoru waenga, whakapakari i te rohe kaha

-EMC600: 600g/㎡, whakapakari matotoru, whakamātotoru pakiaka/mata ārahi

-EMC900: 900g/㎡, whakapakari taumaha, whakapakari ā-rohe o ngā mata nunui

2) Te kōwhiringa o te momo here

-Momo EMC mō te whakaemulsion: he kaha teitei, he ōrite pai, he hototahi pai ki te kapia, ko te kōwhiringa tuatahi mō te whakaheke toto korehau

-Momo paura CMC: tere ake te rumaki, iti ake te utu, he pai mō te whakapiri ā-ringa/tukanga āwhina

-Te mana hau o tāwāhi, ngā mata kaha-teitei: te raupapa whakamomona EMC matua

3) Te taurite o te whānui me te tukanga

-1250mm/1040mm: mata waenga me te iti, he paparanga ā-ringa

- 2500mm me runga ake: he mata nui, he paparanga aunoa, he whakaiti i te takotoranga

3. Kōwhiringa mā te wāhanga: me pēhea te taurite i ngā wāhi rerekē o ngā mata?

1) Te mata o waho o te anga/te paparanga o raro o te paninga tiēre

-E taunakitia ana: EMC225 / EMC300

-Ngā kōrero matua: he mata maeneene, he whakaiti i ngā kōhao iti, he whakapai ake i te āhua me te ātete ki te huarere

2) Te paparanga matua o te anga (paparanga whakawhiti/taurite)

-E taunakitia ana: EMC300

-Ngā kōrero matua: te taurite o te kaha me te urunga, te ōritenga pai ki te kakahu maha-tuaka

3) Te whakapakari i ngā taha o te tukutuku me te taupoki kurupae

-E taunakitia ana: EMC450

-Ngā kōrero matua: he pakari ake, he ātete kutikuti, me te pumau hanganga kua whakapaitia

4) Te taha ārahi, te taha whai, te rohe whakamātotoru o te pakiaka

-E taunakitia ana: EMC600 / EMC900

-Ngā kōrero matua: te tere o te hanganga o ngā paparanga matotoru, te whakaiti i te maha o ngā paparanga, me te whakapai ake i te ātete pānga

5) Ngā mata hau pūngao moana (rehu tote/haumākū nui)

-E taunakitia ana: huruhuru huruhuru iti EMC300/450 + kaihoko whakamakuku ātete-wai

-Ngā kōrero matua: whakapai ake i te ātete ki te koroheketanga me te whakaiti i te mōrearea o te wehewehenga
