I tēnei wā, e rua ngā momo o te takai korohū me te whakahoromata: te kirihou me te hanganga konumohe-kirihou. E ai ki ngā whakaritenga o GB/T10004-2008, e rua ngā taumata o te tunu kai: te tunu i te pāmahana haurua-teitei (i runga ake i te 100°C ki te 121°C) me te tunu i te pāmahana teitei (i runga ake i te 121°C ki te 145°C). Ka taea e ngā piripiri kore-wairewa te hipoki i te whakahoromata tunu kai i te 121°C me raro iho.
Haunga te hanganga paparanga toru/whā e mōhiotia whānuitia ana, ko ngā rauemi matua e whakamahia ana ko PET, AL, NY, me RCPP. Kei te mākete anō hoki ētahi hua korohū me ētahi atu hanganga tono rauemi, pērā i te paninga konumohe mārama, te kiriata polyethylene korohū pāmahana-tiketike, me ētahi atu. Heoi anō, kāore anō kia whakamahia i runga i te tauine nui, i roto rānei i ngā rahinga nui. Ko te pūtake o tā rātou whakamahinga whānui me roa ake te wā me te tirotiro tukanga.
Ngā take tono me ngā pūwāhi tukanga
I roto i te mara o te korohū me te kohua i te pāmahana teitei, kua whakamahia tā mātou kāpia ki roto i te hanganga paparanga e whā o te PET/AL/NY/RCPP mō ngā hua mīti me te raihi piripono me ngā pakiaka rōhi, ā, ka taea katoa te tunu me te whakahoromata i te 121°C. Ko ngā tono i roto i ngā hanganga kirihou ko te WD8166 i roto i ngā tono hiato NY/RCPP 121°C, kua whānuitia te whakamahi me te pakari; Hanganga kirihou konumohe: Ko te tono o te WD8262 i te 121°C AL/RCPP/ kua tino pakari hoki.
I taua wā anō, i roto i te tunu kai me te whakahoromata o te hanganga konumohe-kirihou, he tino pai te mahi ātete reo (ethyl maltol) o WD8268. Hei tāpiri, kua whakaatu a WD8258 i te mahi pai i roto i te hanganga tunu nairona takirua (NY/NY/RCPP) me te paparanga AL/NY (he rerenga korona kotahi te NY) i roto i te hanganga tunu konumohe paparanga e whā.
Ngā whakatūpato tukanga：
Tuatahi, me whakarite me te whakaū i te nui o te piri. Ko te nui o te piri e taunakitia ana mō ngā piri kore-whakarewa kei waenganui i te 1.8-2.5g/m².
Heawhe haumākū taiao
E taunakihia ana kia whakahaerea te haumākū o te taiao i waenga i te 40% -70%. He iti rawa te haumākū, ā, me whakamakuku. Me whakamaroke te haumākū nui. Nā te mea he wāhanga o te wai kei roto i te taiao e uru ana ki te tauhohenga o te kāpia kore-whakarewa, ka taea e te nui o te wai te whakaiti i te taumaha ngota o te kāpia, ā, ka puta ētahi tauhohenga taha, ka pā ki te mahi ātete pāmahana teitei i te wā tunu kai. Nō reira, me whakarerekē te whirihoranga o ngā wāhanga A/B i roto i ngā taiao pāmahana me te haumākū teitei.
Ngā tautuhinga tawhā mō te mahi a te pūrere
Whakatakotoria te kume me te ōwehenga piripiri kia rite ki ngā tauira taputapu me ngā whirihoranga rerekē.
Ngā whakaritenga mō ngā rauemi mata
Ko te papatahi pai, te ngāwari ki te makuku, te mimiti me te nui o te makuku o te kiriata, koia ēnei ngā āhuatanga e tika ana mō te whakaoti i te tunu kai o ngā rauemi hiato.
Te whanaketanga ā muri ake nei：
Mā te whakamahi i te hangarau kore-whakarewa mō te takai tunu kai pāmahana teitei, kei a ia:
1. Painga whai hua, ka taea te whakapai ake i te kaha whakaputa.
2. Painga utu: He nui te nui o te kāpia tunu kai pāmahana-teitei e ahu mai ana i te whakarewa, ko te nuinga o te wā ka whakahaeretia i te 4.0g/m². I te taha maui me te taha matau, ko te rohe kāore e iti iho i te 3.5g/m². Engari ko te nui o te kāpia e whakamahia ana ki te kāpia tunu kai kore-whakarewa he 2.5g/m². Ko ētahi hua he iti iho i te 1.8g te taumaha.
3. Ngā painga o te haumaru me te tiaki taiao
4. Ngā painga penapena pūngao
Hei whakarāpopototanga, nā ōna āhuatanga ahurei, ka whānui ake ngā whakamahinga o ngā piripiri kore-whakarewa ā muri ake nei me te mahi tahi a ngā umanga tā tae, ngā piripiri, me ngā umanga hiato.
