Kua tuanui te whānuitanga o te miro paraihe hei tētahi o ngā miro hangarau nuinga i te hangahanga rēhia, haurangi no te āhua pūmau ki ngā tikanga taiao herenga. He mea nui kia mōhio te aha rawa pea te aronga o tēnei mātātoko mōrearea ki te waimātukutuku me te whakapipiri, mō ngā kaihanga, ngā kaiarahi, me ngā kaiwhakamahi e mātai ana ki ngā hua paraihe mō te roa me te mahi pai. Ko te hanganga molekihere āhuatia o te miro paraihe e homai ana i ana anuanu matua ina pāngia e ngā wāhi āhuarangi rerekē, nō reira he kōwhiringa tino pai mō te maha o ngā whakamahinga puta noa i ngā umanga.
Te Mātauranga i te Kohinga me te Hanganga o te Miro Paraihe
Te Takotoranga Matū o ngā Miro Paraihe
Ko ngā āhuatanga mahi māmā a te miro paraihe e hua ana i tana hanganga karapini takotoranga, e matua ko te polietilene terephthalate (PET). Ko te hanganga roa-kowhiringa tēnei e waihangia ai ngā kaha whakawhitinga kiko tino kaha e āwhina ai i te pae ki te pakari i ngā tikanga taiao rerekē. E tuku mai ana ngā wāhi puawaitanga ki roto i te pouaka kowhiringa i te pakitanga, ā, ko ngā wāhi kore-puawaitanga e tuku ana i ētahi maroke me te whanaketanga mōrearea.
Ko ngā tikanga whanaketanga mō te miro paraihe e whai ana i te karaihe paraihe, i reira ka paraihia te kowhiringa ki tana wāhi paraihanga ka tātarahia mā ngā taputapu tātoru hei waihanga i ngā kiri tuarangi. Ka waihangaia tēnei tikanga i tētahi herekai kotahi o ngā molekiula e pā ana tika ki te ara e urupare ana te miro oti ki ngā take waho pērā i te wera me te paripari. Ko te rahi o te puawaitanga i piki ai i te wā o te whanaketanga e pā ana tino ki ngā īnitau mataora o te miro me ngā īnitau herehere paripari.
Ngā Īnitau Mēra e Pā Ana ki te Mahi
Ko te hanganga o te miro paraiharai ko te āhua o ngā rohe pirihi me ngā rohe kore-pirihi, ā, ko ngā rohe pirihi e tuku ana i te pūmahara āhuatanga me te kaha. Kāre ēnei rohe e pāngia ana e te pārurenga ina pā ana te whakapua, ā, ka āwhina i te miro kia kaua e whai whakapua. Ko ngā rohe kore-pirihi, ahakoa he iti ake te hanganga, kei te pūmau tonu te kōkiri kia kaua ai te āhuatanga nui i raro i ngā tikanga whakamahinga tūmatanui.
Ko ngā āhuatanga mata o te miro paraiharai kei te wāhi matua hira hoki i tōna whakawhitinga me ngā āhuatanga taiao. Ko te mata māmā o ngā miro takitahi e muru ana i te whakapua e mau ana, ā, ka āwhina i te tere noa, ā, ko te ahatanga paripari wai ake o te miro e takahi ana i ngā molekūle wai. Ko te takotoranga o ngā āhuatanga hanganga, me ngā āhuatanga mata e waiho ana i te matēria e pūmau ana i roto i te rohe whānui o ngā whakapuaki āhuarangi, āhuarangi hoki.
Ngā Pūkenga Whakahaere Whakapua
Te Ahatanga Paripari Wai me te Kaha Tū Ki Te Wai
Ko tētahi o ngā painga matua o te mātātoko paraihe kei ōna āhuatanga hydrophobic, e mea ana ia e pērā ake te whakakaha ki te kaukau i te wai.

Ngā Arataki Mō te Pupuri me te Whakamahi
Kāore ngā tikanga rokiroki mō te miro paraihe me ngā hua kua oti i te nui ake i ngā mea e hiahiatia ana mō ngā muka takotoranga, nā te maru o te mātai ki te whakauru waimanu me te pā ki te pāpaku. He tikanga noa pakihi tēnei e āhua ai te kounga o te miro paraihe mō ngā wā roa. Kāore he take pāhekoheko, pāpaku, ika ranei e pā ana ki ngā hua takotoranga nā te pūmahara o te matērihia.
Ko ngā tikanga whakamahinga mō te miro paraihe i te wā o te hanga me te tukutuku e paingia ana e te pūkaha me te tika o te matērihia. Ka pupuri te miro i ana ītao i roto i ngā mahi tukutuku rāwekenga arai, ka iti ake te mōrearea o ngā panonitanga kounga, i te raruraru hoki o te whakangao. Ko te pūkaha nei e āwhina ana kia māmā ake ngā tikanga hanga, me te kounga tika o te hua mutunga.
FAQ
He aha te mea e hua ana ki te miro paraihe ina pāngia e ngā wera nui?
Ko te mātiti pōritehita e mau ana i tana anga me ōna āhuatanga mahi ki ngā wāhi kia rite ki te 150°C (302°F) mō wā roa. Ki ngā wāhi makariri ake e pā ana ki tana wāhi houkai o 250-260°C (482-500°F), ka tbegin te mātiti te parurenga, ka houkai ai. Heoi anō, ko te pātata noa atu ki ngā wāhi makariri ake i te wā pūmahara, i te wā pānui rānei e kore e huaia he pānga moe mai i te mātiti.
Pēhea te pā o te pouri ki te kaha me te roa o te mātiti pōritehita?
Ko te pouri he iti noa ngā pā ki te kaha me te roa o te mātiti pōritehita nā tana anuanu me tana tere iti haumāha. Ka mau tonu te mātiti i te 95% o tana kaha maroke ake, ina whakakīia, kei te wehe atu i ngā mātiti takotoranga e taea ai te ngaro i te 20-50% o tana kaha. Ko tēnei āhua e pai ai te mātiti pōritehita mō ngā whakamahinga e pā ana ki te pouri, ki ngā taiao hoki e makariri ana.
Ka taea te kino i te mātiti pōritehita e ngā wāhi pūmahara me te māmā hoki?
Whakaatu te tarau polyester i te māia ki te whakawhitinga o te wera i roto i ngā tauwae wera noa. Kāore ngā huringa katoa o te wera me te makariri e hāngai ana ki te horoi, te horoi-maru, i te rereketanga o te wera o te wā, e hanga poronga nui, i ngā panonitanga ake i ngā āhuatanga. Ko te pūmahara o te matērahi me te haumāpa iti o te tarau ka whakaiti i te parikara mai i ngā rerekētanga o te wera, ā, ko tēnā he take mō te roa o te ora me te tūhonotanga o te mahi.
He aha te take e maroke ai te tarau polyester tītia ake i ngā whatu taketake?
Ko te āhuatanga maroke tītia o te tarau polyester e hua mai ana i tōna mata kītoki me tōna mōhio iti ki te wai. Kei te mata anake o te whatu ngā molekiula wai engari kāore i roto i te hanganga matērahi, ka taea ai te puhiko tītia. Anō hoki, ko te mata māmā o ngā whatu polyester ka hoatu he itinga iti ake mō te pupuri wai i te upoko o te hanganga herenga o ngā whatu taketake, ā, ko tēnā anō hoki e huritao ai te prosihia maroke.
