I mua i te hanga i te ranunga kore-whakarewa, me pānui marie i ngā tuhinga tukanga whakaputa me ngā whakaritenga me ngā whakatūpato mō te ōwehenga o te piripiri kore-whakarewa, te pāmahana whakamahinga, te haumākū, ngā tikanga whakamaroke, me ngā tawhā tukanga. I mua i te hanga, me whakarite kia kore he āhuatanga rerekē o ngā hua piripiri e whakamahia ana. Kia kitea he āhuatanga rerekē e pā ana ki te matotoru, me mutu tonu, ka whakapā atu ki ngā kaimahi hangarau o te kamupene. I mua i te whakamahi i te mīhini whakakikorua kore-whakarewa, me whakamahana i mua i te pūnaha whakaranu, te pūnaha whakapiri, me te pūnaha whakakikorua. I mua i te hanga i te ranunga kore-whakarewa, me whakarite kia mātao te mata o ngā roera rapa, ngā roera pakari, me ētahi atu.kia ma ngā wāhanga o te taputapu i runga i te mīhini hiato kore-whakarewa.
I mua i te tīmatanga, me whakaū anō mēnā e tutuki ana te kounga o te hua hiato i ngā whakaritenga o te hanga hiato. Ko te kukū mata o te kiriata me neke atu i te 40 dynes, ā, ko te kukū mata o ngā kiriata BOPA me PET me neke atu i te 50 dynes. I mua i te hanga papatipu, me whakamātautau te pono o te kiriata mā roto i ngā whakamātautau hei karo i ngā tūponotanga. Tirohia mēnā he kino, he rerekē rānei o te piri. Mēnā ka kitea he rerekē, maka atu te piri ka horoia te mīhini whakaranu. Whai muri i te whakaū kāore he rerekē o te piri, whakamahia he kapu whakakore hei tirotiro mēnā he tika te ōwehenga o te mīhini whakaranu. Ka taea anake te haere tonu o te hanga i muri i te rerekētanga o te ōwehenga ki roto i te 1%.
I te wā o te tukanga whakaputa, me whakaū te kounga o te hua. Whai muri i te whakaranu noa o te 100-150m, me whakamutu te mīhini hei whakaū mēnā e tutuki ana ngā whakaritenga i te āhua o te ranunga, te nui o te paninga, te taumahatanga, me ētahi atu mea o te hua. I te wā o te tukanga whakaputa, me tuhi ngā tawhā tukanga katoa, tae atu ki te pāmahana taiao, te haumākū, te papa ranunga, me ngā tawhā tukanga taputapu, hei āwhina i te whai me te tautuhi i ngā take kounga.
Ko ngā tawhā hangarau pēnei i te whakamahinga me te taiao rokiroki o te piripiri, te pāmahana whakamahinga, te wā whakahaere, me te ōwehenga o te piripiri kore-whakarewa me tirotiro ki te pukapuka tohutohu hangarau hua. Me whakahaere te haumākū i roto i te taiao awheawhe i waenga i te 40% -70%. Mēnā he ≥ 70% te haumākū, whakapā atu ki ngā kaimahi hangarau a te kamupene, me te whakanui tika i te wāhanga isocyanate (wāhanga KangDa New Material A), me te whakaū mā te whakamātautau iti i mua i te whakamahinga puranga whaimana. Mēnā he ≤ 30% te haumākū o te taiao, whakapā atu ki ngā kaimahi hangarau a te kamupene me te whakanui tika i te wāhanga hydroxyl (wāhanga B), me te whakaū mā te whakamātautau i mua i te whakamahinga puranga. Me tino tupato te whakahaere i te hua i te wā e kawe ana, e utaina ana, e tangohia ana, kia kore ai e taka, e tukinga, e pēhanga nui, me te ārai i te hau me te rā. Me penapena ki ngā āhuatanga hauhautanga, hauhautanga, me te maroke, ā, me pupuri kia hiritia mō te wā rokiroki o te 6 marama. I muri i te otinga o te mahi whakakotahi, ko te awhe pāmahana whakamaroke he 35°C-50°C, ā, ka whakaritea te wā whakamaroke kia rite ki ngā papa whakakotahi rerekē. Ko te makuku whakamaroke e whakahaerehia ana i waenga i te 40% -70%.
