te pūwero me te whakamahana i mua i te maimoatanga
Whakaahuatanga Hua
- Ko te maimoatanga-mua te tukanga matua o te whakapūkara wera-tuku, he pānga nui tēnei ki te kounga o ngā hua whakapūkara. Ko te whakamahana-mua ko te tango hinu, te tango waikura, te horoi wai, te āwhina whakakikorua, te tukanga whakamaroke, me ētahi atu.
I tēnei wā, i roto i te umanga whakapūmau wera-tuku ā-rohe, e whakamahia whānuitia ana te tāke whakapūmau karāhe raima. Nā te whakaurunga o te hangarau whakapūmau wera-tuku matatau ki Ūropi me Amerika, kei te piki haere te whakamahinga o ngā tāke whakapūmau PP (polypropylene)/PE (polyethylene) i roto i ētahi raina whakaputa whakapūmau wera-tuku aunoa.
I runga i te kaha o te paru hinu i runga i te mata o te mea mahi, ka whakakorehia te tango hinu i roto i ētahi tukanga.
Ko te tāke tango hinu, te tāke horoi wai me te tāke āwhina whakakikorua he mea hanga ki te raima te nuinga, ā, ko ētahi he mea hanga ki te rauemi kotahi ki te tāke pīkara.
Te whakamahana i mua i te maimoatanga
Whakamahia te wera para o te hau paru hei whakamahana i ngā tāke katoa i mua i te maimoatanga, tae atu ki te tango hinu.te whakapūkarame te whakakikorua āwhina. Kei roto i te pūnaha wera para:
1) Te tāutanga o te whakawhiti wera whakakotahi i roto i te paipa hau;
2) Kotahi te huinga whakawhiti wera PFA kua tāutahia ki ngā pito e rua o ia puna kaukau;
3) Pūnaha wai ngohengohe;
4) Pūnaha whakahaere.
E toru ngā wāhanga o te whakamahana i mua i te maimoatanga:
① Whakawhiti wera hau haurehu
E ai ki te nui katoa o te wera hei whakamahana, ka hoahoatia, ka hangaia hoki te whakawhiti wera hau kōrere whakakotahi, kia taea ai e te wera te whakatutuki i ngā whakaritenga whakamahana. Mena kāore e taea e te wera para o te hau kōrere te whakatutuki i te hiahia wera whakamahana o te maimoatanga-mua, ka taea te tāpiri i tētahi huinga oumu hau wera hei whakarite i te nui o te hau kōrere.
He mea hanga te whakawhiti wera ki te kowiri tira ātete-wera, ki te paipa rino tui-kore rānei he 20 # me te paninga ārai-waikura penapena-pūngao nano infrared hou. Ko te pūngao mimiti wera he 140% o te wera e mimitihia ana e te whakawhiti wera para noa.
② Whakawhiti wera PFA
③Ouma whakamaroke
Ina uru te hua mākū ki roto i te kaukau konutea, ka pahū, ka pītiti te wai konutea. Nō reira, i muri i te paninga o te āwhina whakakikorua, me whakamaroke anō hoki ngā wāhanga.
Ko te tikanga, kaua te pāmahana whakamaroke e neke ake i te 100°C, kaua hoki e iti iho i te 80°C. Ki te kore, ka taea anake te whakanoho i ngā wāhanga ki roto i te poka whakamaroke mō te wā roa, ka ngāwari ai te mimiti o te konutea pūhaumāota ki roto i te kiriata tote o te āwhina whakakikorua i runga i te mata o ngā wāhanga.
