Whakarāpopototanga: Ka tātarihia e tēnei pepa te ia o te tono me te whanaketanga o te putea retort pāmahana teitei kore-whakarewa, ā, ka whakaurua ngā kaupapa matua o te whakahaere tukanga, tae atu ki te tautuhinga me te whakaū i te nui o te paninga, te whānuitanga haumākū o te taiao, te tautuhinga tawhā o te mahi taputapu, me ngā whakaritenga o ngā rauemi mata, me ētahi atu.
Kua roa te tikanga korohū me te whakahoromata. I Haina, nā te whanaketanga o ngā piri kore-whakarewa, tata katoa i whakamahia hei whakakotahi i ngā takai tunu kai pāmahana teitei. Ināianei, kua tekau tau te whanaketanga o ngā piri kore-whakarewa i Haina, me ngā whakapainga nui i roto i ngā taputapu, ngā rauemi mata, ngā kaimahi, me te hangarau. I roto i te horopaki o ngā kaupapa here tiaki taiao ā-motu, kua hangaia e ngā umanga tā tae he wāhi whanaketanga nui ake mō ngā piri kore-whakarewa kia rapu hua me te whanaketanga, e akiakihia ana e te āhuatanga o te pikinga o te kaha whakaputa. Nō reira, kei te whānui haere te kapinga o ngā piri kore-whakarewa, ā, ko te korohū, te whakahoromata, me te takai tētahi o aua mea.
1. Te ariā o te whakahoromata tunu kai me te whakamahinga o ngā piripiri kore-whakarewa
Ko te whakahoromata tunu kai he tukanga hiri me te patu huakita i roto i ngā ipu ārai-hau mā te pēhi me te whakamahana. Mō te hanganga tono, e rua ngā momo o te takai korohū me te whakahoromata: te kirihou me te hanganga konumohe-kirihou. E rua ngā taumata o ngā tikanga tunu kai: te tunu i te pāmahana haurua-teitei (neke atu i te 100° C ki te 121° C) me te tunu i te pāmahana teitei (neke atu i te 121° C ki te 145° C). Ka taea e ngā piripiri kore-whakarewa te hipoki i te whakahoromata tunu kai i te 121° C me raro iho.
Mō ngā hua e tika ana, me whakamārama poto e au te āhuatanga tono o ētahi hua o Kangda:
Hanganga kirihou: Kua whānuitia te whakamahinga o te WD8116, ā, kua tino whakamahia i roto i te NY/RCPP i te 121° C;
Hanganga kirihou konumohe: Te whakamahinga o WD8262 i roto i te AL/RCPP i te 121° He tino pakeke hoki a C.
I taua wā anō, i roto i te tunu kai me te whakahoromata o te hanganga konumohe-kirihou, he tino pai hoki te mahi ātete reo (ethyl maltol) o WD8262.
2. Te Aronga Whakawhanake ā-Mārama o te Tunu Kai i te Pāmahana Teitei
Haunga ngā hanganga paparanga e toru, e whā hoki e mōhiotia whānuitia ana, ko ngā rauemi matua e whakamahia ana ko PET, AL, NY, me RCPP. Heoi anō, kua tīmata hoki te whakamahi i ētahi atu rauemi ki ngā hua tunu kai i te mākete, pērā i te paninga konumohe mārama, te kiriata polyethylene tunu kai pāmahana teitei, me ētahi atu. Heoi anō, kāore anō kia whakamahia i runga i te tauine nui, i roto rānei i ngā rahinga nui, ā, me whakamātautau tonu te pūtake o tā rātou whakamahinga whānui mō te wā roa me ētahi atu tukanga. I roto i te kaupapa, ka taea hoki te whakamahi i ngā piripiri kore-whakarewa, ā, he mea pai kia manatokohia, kia whakamatautauria hoki te pānga tuturu e ngā umanga tā tae.
Hei tāpiritanga, kei te whakapai ake hoki ngā piripiri kore-whakarewa i ā rātou mahi e pā ana ki te pāmahana whakahoromata. I tēnei wā, kua nui te ahunga whakamua kua puta i roto i te manatoko mahi o ngā hua kore-whakarewa a Konda New Materials i raro i ngā tikanga o te 125° C me te 128° C, ā, kei te whakapau kaha kia eke ki ngā taumata tunu pāmahana teitei ake, pērā i te 135° C te tunu kai, tae atu ki te 145° Te tunu kai.
3. Ngā kaupapa matua o te tono me te whakahaere tukanga
3.1Te whakatakoto me te whakaū i te nui o te piripiri
I ēnei rā, kei te piki haere te rongonui o ngā taputapu kore-whakarewa, ā, he maha ngā kaihanga kua whiwhi wheako me ngā māramatanga ki te whakamahi i ngā taputapu kore-whakarewa. Heoi, me whai tonu te tukanga whakahoromata tunu kai pāmahana teitei i tētahi nui o te piripiri ā-papa (arā, te matotoru), ā, kāore te nui o te piripiri i roto i ngā tukanga whānui e ranea hei whakatutuki i ngā hiahia o te whakahoromata tunu kai. Nō reira, ina whakamahia te piripiri kore-whakarewa mō ngā takai tunu kai hiato, me whakanui ake te nui o te piripiri e pania ana, me te awhe e taunakitia ana ko te 1.8-2.5g/m².
3.2 Te awhe haumākū o te taiao
I ēnei rā, he maha ngā kaihanga kei te tīmata ki te mōhio me te aro nui ki te pānga o ngā āhuatanga taiao ki te kounga o te hua. Whai muri i te tiwhikete me te whakarāpopototanga o ngā take mahi maha, e taunakihia ana kia whakahaeretia te haumākū o te taiao i waenga i te 40% me te 70%. Mena he iti rawa te haumākū, me whakamakuku, ā, ki te nui rawa te haumākū, me whakamaroke. Nā te mea he wāhanga o te wai i roto i te taiao e whai wāhi ana ki te tauhohenga o te kāpia kore-whakarewa. Heoi, mā te nui o te wai e whai wāhi ai ka whakaiti i te taumaha ngota o te kāpia, ka puta ai 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.
3.3 Ngā tautuhinga tawhā mō te whakahaere o te pūrere
Ka whakatakotoria ngā tautuhinga tawhā kia rite ki ngā tauira me ngā whirihoranga taputapu rerekē; ko te tautuhinga kume me te tika o te ōwehenga tohatoha he taipitopito katoa o te whakahaere me te whakaū. Ko te taumata tiketike o te aunoatanga, te tika, me te ngāwari o te whakahaere o ngā taputapu kore-whakarewa he painga anō, engari e kapi ana hoki i te hiranga o te ātaahua me te tupato kei muri i tēnā. Kua whakanuia tonutia e mātou he tukanga ātaahua ngā mahi whakaputa kore-whakarewa.
3.4 Ngā whakaritenga mō ngā rauemi mata
Ko te papatahi pai, te mākū o te mata, te tere mimiti, tae atu ki te nui o te makuku o ngā rauemi mata angiangi, he āhuatanga tika ēnei mō te whakaoti i te tunu kai o ngā rauemi hiato.
- Ngā painga o ngā rauemi whakahiato kore-whakarewa
I tēnei wā, ko ngā hua tunu kai me ngā hua whakahoromata i roto i te umanga e whakamahi ana i ngā piripiri e hangai ana ki te whakarewa mō te whakaranu maroke. Ki te whakatauritea ki te whakaranu maroke, ko ngā painga o te whakamahi i ngā hua tunu kai whakaranu kore-whakarewa koia ēnei:
4.1ngā painga whai hua
Ko te painga o te whakamahi i ngā piripiri kore-whakarewa ko te whakanui ake i te kaha whakaputa. E mōhiotia whānuitia ana, he iti te tere whakaputa mā te whakamahi i te hangarau hiato maroke hei tukatuka i ngā rauemi tunu me te whakahoromata i te pāmahana teitei, tata ki te 100m/min. He pai ētahi āhuatanga taputapu me te whakahaere whakaputa, ā, ka taea te eke ki te 120-130m/min. Heoi, kāore ngā āhuatanga i te tino pai, 80-90m/min anake, he iti iho rānei. He pai ake te kaha whakaputa taketake o ngā piripiri kore-whakarewa me ngā taputapu hiato i te hiato maroke, ā, ka taea e te tere hiato te eke ki te 200m/min.
4.2painga utu
He nui te nui o te kāpia e pania ana ki 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 Mauī, matau hoki, kāore te rohe e iti iho i te 3.5g/m²；Ahakoa ko te nui o te kāpia i pania ki te kāpia tunu kai kore-whakarewa he 2.5g/m² Ki te whakatauritea ki ngā tikanga e hangai ana ki te whakarewa, he nui anō te painga utu nā te mea he nui te ihirangi piripiri kei roto.
4.3Ngā painga o te haumaru me te tiaki taiao
I te wā e whakamahia ana te kāpia tunu kai pāmahana-tiketike e hangai ana ki te whakarewa, me tāpiri he nui o te ethyl acetate hei whakawaiwai, he mea kino tēnei ki te tiaki taiao me te haumaru o ngā awheawhe whakaputa. He ngāwari hoki ki te raru o te nui o ngā toenga whakarewa. Ā, kāore he āwangawanga pēnei mō ngā piripiri kore-whakarewa.
4.4Ngā painga penapena pūngao
He tino teitei te ōwehenga whakaora o ngā hua hiato piripiri e hangai ana ki te whakarewa, ko te 50 pea te nuinga.° C, neke atu rānei; Me 72 hāora, neke atu rānei te roa o te wā pakari. He tere te tere o te tauhohenga o te kāpia tunu kai kore-whakarewa, ā, ka iti ake te hiahia mō te pāmahana whakamaroke me te wā whakamaroke. I te nuinga o te wā, ko te pāmahana whakamaroke he 35° C~48° C, ā, ko te wā whakaora he 24-48 hāora, ka taea ai e ngā kiritaki te whakapoto i te huringa.
5. Whakamutunga
Hei whakarāpopototanga, nā ngā āhuatanga ahurei o ngā piripiri kore-whakarewa, kua mahi tahi, kua tautoko hoki ngā umanga tā tae, ngā umanga piripiri, me ngā umanga hanga taputapu hiato kore-whakarewa tetahi i tetahi mō ngā tau maha, e whakarato ana i ngā wheako me ngā mātauranga whai hua i roto i ā rātou ake mara. E whakapono ana mātou he whānui ake ngā tono a ngā piripiri kore-whakarewa a meake nei. Ko te rapunga whakaaro whanaketanga o Kangda New Materials ko "kei te kaha mātou ki te waihanga uara mō ngā kiritaki me te neke i a rātou". Ko tā mātou tumanako ka taea e ā mātou hua tunu kai pāmahana teitei te āwhina i ngā umanga tā tae ki te tūhura i ngā mara tono hiato kore-whakarewa hou.
