Ko ngā painga me ngā ngoikoretanga o ngā mea e rua ka whakatauritea penei:
He tukanga pokepokea tuwhera te whakatakoto-ā-ringa, ā, e 65% o ngā mahi e mahia ana i tēnei wāmuka karāhengā hiato polyester kua whakapakaritia. Ko ōna painga he nui te mana ki te whakarerekē i te āhua o te pokepokea ai, he iti te utu o te pokepokea ai, he kaha te urutau, e mōhiotia ana te mahi a te hua e te mākete, ā, he iti te haumitanga. Nō reira he tino pai mō ngā kamupene iti, engari mō ngā umanga moana me te rererangi hoki, he wāhanga nui tēnei i te nuinga o te wā. Heoi anō, he maha ngā raruraru kei roto i tēnei tukanga. Mena ka nui ake te tukunga o te matū waro mimiti (VOC) i te paerewa, he nui te pānga ki te hauora o ngā kaiwhakahaere, he ngāwari te ngaro o ngā kaimahi, he maha ngā herenga mō ngā rauemi e whakaaetia ana, he iti te mahi a te hua, ā, ka maumauria te kapia, ka whakamahia i roto i te nui, inā koa te hua. Kāore i te pumau te kounga. Ko te ōwehenga omuka karāhe me te kapia, te matotoru o ngā wāhanga, te tere whakaputa o te paparanga, me te ōritetanga o te paparanga, ka pāngia katoatia e te kaiwhakahaere, ā, me whai hangarau, wheako me te kounga pai ake te kaiwhakahaere.Te kapiaKo te nui o ngā hua whakatakoto-ā-ringa e tata ana ki te 50%-70%. Ko te tukunga VOC o te tukanga whakatuwheratanga pokepokea ai e neke atu ana i te 500PPm, ā, ko te whakakorikori o te styrene e tae ana ki te 35%-45% o te nui e whakamahia ana. Ko ngā ture o ngā whenua rerekē ko te 50-100PPm. I tēnei wā, ko te nuinga o ngā whenua ke e whakamahi ana i te cyclopentadiene (DCPD) me ētahi atu kapia tuku styrene iti, engari kāore he whakakapinga pai mō te styrene hei monomer.
Whāriki muka karāhe te tukanga whakatakoto ringaringa
Te kapia korehauHe tukanga whakaputa iti te utu i whakawhanakehia i ngā tau 20 kua pahure ake nei, he tino pai mō te whakaputa hua nui. Ko ōna painga koia ēnei:
(1) He tino pai te mahi a te hua, ā, he nui te hua.Mō te taua mea anōmuka karāheI roto i ngā rauemi mata, ka taea te whakapai ake i te kaha, te pakari me ētahi atu āhuatanga ā-tinana o ngā wāhanga i whakaurua ki te kapia korehau mā te neke atu i te 30%-50% ki te whakataurite ki ngā wāhanga i whakatakotoria ā-ringa (Ripanga 1). I muri i te whakau o te tukanga, ka tata te hua ki te 100%.

(2) He pumau te kounga o te hua, ā, he pai te āheinga ki te whakahoki anō.Kāore i te nui te pānga o ngā kaiwhakahaere ki te kounga o te hua, ā, he nui te ōritetanga ahakoa he wāhanga kotahi, he wāhanga rānei i waenga i ngā wāhanga. Kua tāpirihia te muka o te hua ki roto i te pokepokea ai kia rite ki te nui kua tohua i mua i te werohanga o te kapia, ā, he ōrite te ōwehenga kapia o ngā wāhanga, ko te tikanga he 30%-45%, nō reira he pai ake te ōritetanga me te auautanga o te mahi hua i ngā hua tukatuka ā-ringa. He nui ake, he iti ake ngā hapa.
(3) Ka whakapaitia te mahi ārai-ngoikore, ka taea ai te whakaiti i te taumaha o te hanganga.Nā te nui o te muka, te iti o te porosity me te pai o te mahi a te hua, inā koa te whakapainga o te kaha interlaminar, ka tino pai ake te ātete o te hua ki te ngenge. Mēnā he rite tonu te kaha, te pakari rānei o ngā whakaritenga, ka taea e ngā hua i hangaia mā te tukanga whakauru korehau te whakaiti i te taumaha o te hanganga.
(4) He pai mō te taiao.He tukanga pokepokea kati te tukanga werohanga kapia korehau, e herea ana ngā mea matūriki me ngā poke hau paitini ki roto i te putea korehau. He iti noa iho ngā mea matūriki e kitea ana ina whakapūhia te papu korehau (ka taea te tātari) me te whakatuwheratanga o te oko kapia. Kāore e neke ake ngā tukunga VOC i te paerewa o te 5PPm. Ka tino whakapai ake hoki tēnei i te taiao mahi mō ngā kaiwhakahaere, ka whakau i te hunga mahi, ā, ka whakawhānui ake i te whānuitanga o ngā rauemi e wātea ana.
(5) He pai te āhua o te hua.Mā te tukanga whakauru kapia korehau ka taea te hanga i ngā rara whakapakari, ngā hanganga hanawiti me ētahi atu whakaurunga i te wā kotahi, ka whakapai ake i te kounga o te hua, kia taea ai te hanga i ngā hua nui pēnei i ngā taupoki pā, ngā takere kaipuke me ngā hanganga o runga.
(6) Whakaitihia te whakamahinga o ngā rauemi mata me te mahi.I roto i te whakatakotoranga kotahi, ka whakaitihia te nui o te kapia mā te 30%. He iti ake te para, he iti iho i te 5% te tere o te ngaronga o te kapia. He nui ake te hua o te mahi, neke atu i te 50% te penapena mahi ki te whakataurite ki te tukanga whakatakotoranga ā-ringa. Ina koa i roto i te hanga i ngā āhuahanga nui me te uaua o ngā wāhanga hanganga hanawiti me ngā wāhanga hanganga whakapakari, he nui ake te penapena rauemi me te mahi. Hei tauira, i roto i te hanga o ngā urungi poutū i roto i te umanga rererangi, ka whakaitihia te utu o te whakaiti i ngā whakapiripiri mā te 365% ki te whakataurite ki te tikanga tuku iho, kāore te taumaha o te hua e rerekē, ā, he pai ake te mahi.
(7) He pai te tika o te hua.He pai ake te tika o ngā āhuatanga (te matotoru) o ngā hua tukanga whakauru kapia korehau i ērā o ngā hua whakatakoto-ā-ringa. I raro i taua whakatakoto-ā-ringa, ko te matotoru o ngā hua hangarau tohatoha kapia korehau whānui he 2/3 o ērā o ngā hua whakatakoto-ā-ringa. Ko te rerekētanga matotoru o te hua he ±10%, ko te tukanga whakatakoto-ā-ringa he ±20% te nuinga. He pai ake te papatahi o te mata o te hua i ērā o ngā hua whakatakoto-ā-ringa. He maeneene te pakitara o roto o te hua taupoki o te tukanga whakauru kapia korehau, ā, he paparanga kapia kei roto i te mata, kāore e hiahiatia he paninga o runga. He iti ake te mahi me ngā rauemi mō ngā tukanga oro me te peita.
Heoi anō, he ngoikoretanga anō hoki kei te tukanga whakauru kapia korehau o nāianei:
(1) He roa te wā e pau ana ki te whakarite, ā, he uaua ake.Me tika te whakatakotoranga, te whakatakotoranga o ngā mea whakakorikori, ngā ngongo whakakorikori, te hiri korehau whai hua, me ētahi atu. Nō reira, mō ngā hua iti, he roa ake te wā tukatuka i te tukanga whakatakotoranga ā-ringa.
(2) He nui ake te utu whakaputa, ā, he nui ake ngā para e puta mai ana.Ko ngā rauemi āwhina pēnei i te kiriata pēke korehau, te rauemi whakawhiti, te kakahu tuku me te ngongo whakawhiti he mea whakakore katoa, ā, he maha o ēnei e kawemai ana i tēnei wā, nō reira he nui ake te utu whakaputa i te tukanga whakatakoto-ā-ringa. Engari ko te nui ake o te hua, ko te iti ake o te rerekētanga. I te mea kei te noho ngā rauemi āwhina i te rohe, ka iti haere te rerekētanga utu. Ko te rangahau o nāianei mō ngā rauemi āwhina ka taea te whakamahi i ngā wā maha he aronga whanaketanga o tēnei tukanga.
(3) He tūponotanga kei roto i te tukanga hanga.Ina koa mō ngā hua hanganga nunui, matatini hoki, ina kore e taea te whakauru i te kapia, ka māmā noa te tango atu i te hua.
Nō reira, me whai rangahau tuatahi pai ake, me whakahaere tika i ngā tukanga, me ngā mahi whakatikatika whai hua hoki, kia angitu ai te tukanga.
