Ngā āhuatanga me ngā pūkenga tā o te waituhi wai mō te pepa kōpikopikopouaka tiakarete
He hua waituhi pai mō te taiao te waituhi waituhi, ā, kua rongonui haere i ngā tau tata nei.pouaka kekeHe aha te rerekētanga i waenga i te waituhi wai me te waituhi tānga whānui, ā, he aha ngā āhuatanga me aro atu ki te whakamahinga? I konei, ka whakamāramahia e Meibang māu.
Kua roa te whakamahinga o te waituhi wai hei tā i te pepa kōpikopiko i tāwāhi, ā, neke atu i te 20 tau i te kāinga. Kua whanake te tānga pepa kōpikopiko mai i te tānga mata (tānga whakaora), te tānga taurite (tānga taurite) me te tānga horoi wai pereti rapa ki te tānga waituhi wai whakangāwari ngāwari o ēnei rā. Kua whanake hoki te waituhi wai whakangāwari ngāwari mai i te raupapa kapia whakarerekētia waikawa rosin-maleic (te kounga iti) ki te raupapa kapia kiriaku (te kounga teitei). Kei te neke haere hoki te pereti tā mai i te pereti rapa ki te pereti kapia. Kua whanake haere hoki te mīhini tā mai i ngā mīhini tā tae kotahi, tae rua rānei me ngā roera nui ki ngā mīhini tā FLEXO tae toru, tae whā rānei.
He rite tonu te hanganga me ngā āhuatanga o ngā waituhi wai-wai ki ērā o ngā waituhi tānga whānui. Ko ngā waituhi wai-wai he mea hanga mai i ngā tae, ngā here, ngā āwhina me ētahi atu wāhanga. Ko ngā tae ko ngā tae o te waituhi wai-wai, e hoatu ana ki te waituhi he tae motuhake. Hei hanga i te ahua kanapa i roto i te tānga flexographic, ko ngā tae he mea whakamahi i ngā tae he pai te pumau matū me te kaha tae teitei; ko te here he wai, he kapia, he matū amine me ētahi atu whakarewa waro. Ko te kapia te wāhanga nui rawa atu i roto i ngā waituhi wai-wai. Ko te kapia kiriaku wai-wai te nuinga o te wā e whakamahia ana. Ko te wāhanga here e pā tika ana ki te mahi piri, te tere maroke, te mahi ārai-piri, me ētahi atu o te waituhi, ā, ka pā hoki ki te kanapa me te tuku waituhi o te waituhi. Ko ngā matū amine te nuinga o te wā e pupuri ana i te uara PH kawakore o te waituhi wai-wai, kia pai ake ai te pānga tā o te kapia kiriaku. Ko te wai, ko ētahi atu whakarewa waro rānei, he kapia wairewa te nuinga, ka whakatikatika i te matotoru me te tere maroke o te waituhi; ko ngā āwhina ko: te tango pahuka, te aukati, te whakaū, te waiwhakarewa, me ētahi atu.
I te mea he hopi te waituhi wai, he ngāwari te puta o ngā mirumiru i te whakamahinga, nō reira me tāpiri he hinu silicone hei tango i te pahuka hei aukati me te whakakore i ngā mirumiru, me te whakapai ake i te mahi tuku o te waituhi. Ka whakamahia ngā aukati hei aukati i te tere maroke o te waituhi wai, hei ārai i te maroke o te waituhi i runga i te roera anilox me te whakaiti i te whakapiri. Ka taea e te whakau te whakarite i te uara PH o te waituhi, ā, ka taea hoki te whakamahi hei wairewa hei whakaiti i te matotoru o te waituhi. Ka whakamahia te wairewa hei whakaiti i te tae o te waituhi wai, ā, ka taea hoki te whakamahi hei whakamārama hei whakapai ake i te kanapa o te waituhi wai. Hei tāpiri, me tāpiri he ware pi ki te waituhi wai hei whakanui ake i tōna ātete ki te kakahu.
Ka taea te whakaranu i te waituhi wai ki te wai i mua i te whakamaroke. Kia maroke te waituhi, kāore e taea te wairewa ki te wai me te waituhi. Nō reira, me whakaoho rawa te waituhi waituhi i mua i te whakamahinga kia ōrite tonu te hanganga o te waituhi. Ina tāpirihia te waituhi, mēnā he paru kei roto i te waituhi toenga i roto i te tāke waituhi, me tātari tuatahi, kātahi ka whakamahia me te waituhi hou. I te wā e tā ana, kaua e tukua kia maroke te waituhi i runga i te rōra anilox kia kore ai e ārai i te kōhao waituhi. Mā te aukati i te tukunga rahinga o te waituhi ka kore e pumau te tā. I te wā o te mahi tā, me whakamakuku tonu te pereti whakapiko ki te waituhi kia kore ai e ārai i te tauira tuhinga i runga i te pereti tā i muri i te maroke o te waituhi. Hei tāpiri, kua kitea ina paku teitei ake te matotoru o te waituhi waituhi, kāore e tika kia tāpiri noa i te wai kia kore ai e pā ki te pumau o te waituhi. Ka taea e koe te tāpiri i te nui o te whakaū tika hei whakatika.
