I roto i te mara o te whakakikorua kore-whakarewa, he raruraru uaua te whakakorua pāmahana teitei i ngā tau kua pahure ake nei. Ahakoa te whanaketanga o ngā taputapu, ngā piripiri me ngā hangarau, kua nui te whakamahinga o te whakakikorua kore-whakarewa mō te kirihou me te kirihou i raro i te 121℃ whakakorua i waenga i ngā kaihanga takai ngāwari. Heoi anō, kei te piki haere te maha o ngā wheketere e whakamahi ana i te PET/AL, AL/PA me te Kirihou/AL mō te whakakorua 121℃.
Ka arotahi tēnei pepa ki ngā whanaketanga hou, ngā pūwāhi whakahaere i te wā o te hanga me ngā au auaha o te heke mai.
1. Te whanaketanga hou
E rua ngā momo paparanga o ngā pēke retort, arā, he kirihou/kirihou, he kirihou/konumohe hoki. E ai ki ngā whakaritenga a GB/T10004-2008, ko te tukanga retort he paerewa pāmahana haurua-teitei (100℃ – 121℃) me te pāmahana teitei (121℃ – 145℃). I tēnei wā, kua hipokina e te whakakī kore-whakarewa te maimoatanga whakahoromata 121℃ me raro iho i te 121℃.
Haunga ngā rauemi e mōhiotia ana pērā i te PET, AL, PA, RCPP, e whakamahia ana mō ngā paparanga e toru, e whā rānei, ka puta mai ētahi atu rauemi pērā i ngā kiriata konumohe mārama, me te PVC retort i te mākete. Ahakoa kāore i te hangaia, i te whakamahia rānei i roto i te tauine nui, me roa ake te wā me te whakamātautau mō aua rauemi kia whakamahia nuitia.
I tēnei wā, kua angitu te whakamahinga o tā mātou piripiri WD8262A/B ki runga i te papa PET/AL/PA/RCPP, ā, ka taea te tae ki te 121℃ te pāmahana. Mō te papa kirihou/kirihou PA/RCPP, he whānui te whakamahinga o tā mātou piripiri WD8166A/B, ā, kua whanake haere ngā tauira.
Ko te uauatanga o te whakakikorua kore-whakarewa, te PET/Al tānga kua ea inaianei e tā mātou WD8262A/B. I mahi tahi mātou me ētahi kaiwhakarato taputapu, i whakamātautau me te whakarerekē mō ngā mano wā, ā, i te mutunga ka hangaia te WD8262A/B me te mahi pai. I te kawanatanga o Hunan, he nui te hiahia o ā mātou kiritaki ki ngā whakakikorua konumohe, ā, he watea ake mā rātou te whakamātautau. Mō te papa PET/AL/RCPP tānga, ka pania ngā paparanga katoa ki te WD8262A/B. Mō te PET/PA/AL/RCPP tānga, ka whakamahia ngā paparanga PET/PA me te AL/RCPP ko te WD8262A/B. Ko te taumaha o te paninga he tata ki te 1.8 – 2.5 g/m2, ā, ko te tere kei te 100m/min – 120m/min.
Kua tino angitu ngā hua kore-whakarewa a Kangda i raro i te 128℃, ā, kei te mau tonu te wero mō te maimoatanga pāmahana teitei 135℃ tae noa ki te 145℃. Kei te rangahauhia hoki te ātete matū.
WHAKAMĀTAUTAU WHAKAMAHI
| TAUIRA | NGĀ RANGI | TE KAHA O TE WHAKANGA I MURI I TE 121℃ WHAKAHOKI |
| WD8166A/B | PA/RCPP | 4-5N |
| WD8262A/B | AL/RCPP | 5-6N |
| WD8268A/B | AL/RCPP | 5-6N |
| WD8258A/B | AL/NY | 4-5N |
Ngā Uauatanga:
Ko te raru matua mō te hanga i ngā putea retort konumohe papa-whā ko te kimi i te huinga tika o ngā rauemi rerekē, tae atu ki ngā kiriata, ngā piripiri, te mangumangu me te whakarewa. Ina koa, ko te hanga PET/AL kua tāia katoatia tēnei paparanga o waho te mea tino uaua. I mua, i pāngia mātou e ēnei āhuatanga, i te wā i haria ai e mātou ngā rauemi mai i ngā kiritaki ki tā mātou taiwhanga me te whakamātautau i ngā huānga katoa tae atu ki ngā taputapu, kāore i kitea he hapa. Heoi, i te wā i whakakotahihia ai e mātou ngā huānga katoa, kāore i pai te mahi a ngā papa whakanikoniko. Mēnā kei raro katoa i te mana whakahaere ngā hangarau, ngā taputapu, me ngā rauemi katoa, ka taea te hanga angitu i te papa. Ka taea e ētahi atu wheketere te hanga i tēnei papa, ehara i te mea ka taea e tetahi te angitu anō hoki.
2. Ngā pūwāhi whakahaere i te wā hangahanga
1) Ko te taumaha o te paninga he tata ki te 1.8 – 2.5 karamu/m2.
2) Te haumākū o te taiao
E taunakihia ana kia whakahaerehia te haumākū o te rūma i waenga i te 40% – 70%. Ka whai wāhi te wai i roto i te hau ki te tauhohenga o te piripiri, ka whakaitihia e te haumākū nui te taumaha ngota o te piripiri, ā, ka puta mai ētahi tauhohenga iti, ka pā ki te mahi a te ātete whakautu.
3) Ngā tautuhinga mō te laminator
E ai ki ngā mīhini rerekē, me whakamātau i ngā tautuhinga tika pēnei i te kume, te pēhanga, me te whakaranu kia kitea ai te whakamahinga tika, kia papatahi ai hoki ngā papa whakaniko.
4) Ngā whakaritenga mō ngā kiriata
Ko te papatahi pai, te uara dyne tika, te whakaheke me te nui o te makuku, koia katoa ngā āhuatanga e tika ana mō te whakakirikiri retort.
3. Ngā au o te heke mai
I tēnei wā, kei runga i ngā takai ngāwari te whakamahinga o te whakakikorua kore-whakarewa, ā, he whakataetae nui tēnei. Mō ngā whakaaro whaiaro, e toru ngā huarahi hei whakawhanake i te whakakikorua kore-whakarewa.
Tuatahi, kotahi te tauira me ngā tono maha. Ka taea e te kotahi hua te hanga i te nuinga o ngā papa o te kaihanga takai ngāwari, ka taea te penapena i te nui o te wā, te piripiri me te whakapiki i te pai o te mahi.
Tuarua, he pai ake te mahi, e ātete ana ki te wera me ngā matū.
Hei whakamutunga, te haumaru o te kai. Ināianei he nui ake ngā mōrearea o te whakapiripiri kore-whakarewa i te whakapiripiri turanga-whakarewa nā te mea he here kei runga i ngā hua mahi teitei pēnei i ngā putea whakahoki 135℃.
Heoi anō, kei te tere haere te whanaketanga o te whakarārangi kore-whakarewa, ā, kua puta mai ngā hangarau hou. Ā tōna wā, tera pea ka nui te pānga o te whakarārangi kore-whakarewa ki te mākete mō ngā takai ngāwari me ētahi atu mara.
