He aha ngā rauemi e whakamahia ana i roto i ngā pēke tātari kawhe? He aratohu rapu rauemi pakihi-ki-te-pākihi
He aha ngā rauemi e whakamahia ana mō ngā pēke tātari kawhe?
He aratohu rapu rauemi me te hangarau whai hua mō ngā kaituku tākai, ngā kaihoko ratonga kai, me ngā tīma hokohoko tauwhiro.
I te neke haere o ngā pēke maturuturu takitahi me ngā pēke ringihanga mai i ngā mākete motuhake o Āhia ki ngā hokohoko o te ao, ka tūtaki ngā kaiwhakahaere hoko ki tētahi ao rauemi kapi tonu. Me piri tonu koe ki te pepa tātari tuku iho, me neke ki ngā mea hanga kore-whatu, me haumi rānei ki te mata PLA tipu?
E whakamārama ana tēnei aratohu i ngā mahi e hiahiatia ana hei hanga i tētahi putea tātari kawhe, me pēhea te rere o ēnei rauemi i roto i ngā mīhini tākai tūturu, me pēhea hoki te whiriwhiri i te papa tika mō ngā whāinga whakahaere me te oranga tonutanga o tō waitohu.

Ngā Papa Matua e Toru e Ruku Hōhonu ana
1. Ngā Pepa Tātari Cellulosic
Koinei te paerewa matarohia. He mea hanga mai i te penupenu rakau, i ngā muka abaka rānei (hemp Manila), ka whakawhirinaki te pepa ki tētahi mata matotoru, kua whakatakotoria mākū hei hopu i ngā pūtake. Heoi, kāore te pepa parakore e hiri wera i runga i tētahi mīhini hiri whakakī-āhua (FFS) hou. Hei whakatika i tēnei, ka whakaranua e ngā mira he paparanga angiangi o ngā muka polyethylene (PE) polypropylene (PP) rānei ki tētahi taha kia kati ai ngā hiri o te putea i raro i te wera.
2. Ngā mea hanga kore-whatu (PP me te PET)
I riro i ngā mea hanga-ā-ringa te mākete putea maturuturu nā te mea he pakari. He mea hanga mai i ngā pūhui hinu spunbond, i ngā pūhui hinu whakarewa rānei, kāore e tere te haehae o te polypropylene (PP) me te polyethylene terephthalate (PET)—ahakoa ka rumakina ki te wai e tata ana ki te kohua. He tere te oma i runga i ngā raina tākai aunoa, ā, he iti noa te wā e kore ai e whakamahia.
3. Ngā Wāhi Kore-Whatu PLA e Hangai Ana ki te Koiora
Ko te waikawa polylactic (PLA) te whakautu hou ki ngā ture kirihou. I ahu mai i ngā māngaro tipu kua whakapūkaratia pērā i te kānga, te tō rānei, he tātari kawhe kore-whatu i hangaia mai i te PLA te āhua me te mahi he rite ki te mata hangai, engari kua whakamanahia he mea ka taea te whakapūkara i roto i te ahumahi. Kei te tere haere te noho hei paerewa mō ngā waitohu motuhake e aro ana ki ngā hokohoko teitei.
Te Hanganga o ēnei Rauemi
Pepa (Te Tukanga Whakatakoto Makuku)
Ka iri ngā muka i roto i te paru wai, ka horahia ki runga i tētahi mata waea tere-rahi. I te mimiti haere o te wai, ka kukume ngā hononga hauwai i ngā muka tipu kia noho hei rau.
Kore-Whatu (Hononga Spunbond me te Hononga Ultrasonic)
Ka rewahia ngā kapia polima (ahakoa PP, PLA rānei), ka panaia mā roto i ngā pūwero moroiti (ngā miro hurihuri), ka whakatakotoria ki roto i te kupenga o ngā miro tonu. Kātahi ka pēhia te kupenga e ngā roera wera ki ngā pūwāhi pa motuhake hei raka i ngā muka me te kore e whakamahi i ngā kāpia matū.

Ngā Kaha me ngā Here o te Ao Tūturu
Ngā Ranunga Pepa me te Apaka
He iti ake te utu rauemi mō ia waeine; he kakano pepa waro kua mōhiotia.
Ka taea te mimiti i ngā hinu kakara ngawari; kāore e taea te whakawairakau nā ngā paparanga hiri kirihou.
Polypropylene / PET
He tino pono te mīhini (80+ pēke/meneti); he tino kaha te kume mākū.
Te piki haere o ngā mōrearea ture mō ngā kirihou whakamahi kotahi puta noa i te ao.
Pāpāho Tātari PLA
Kāore he reka pepa; he mārama te tirohanga; e tutuki ana i ngā tohutohu ESG a te kamupene.
35%–60% te rauemi mata kounga teitei; me whaiti ake ngā matapihi hiri wera.
Te Whakataurite i ngā Rauemi ki te Tono
Ngā Pēke Taringa Whakairi Maturuturu Motuhake
Ko ngā kaihanga kawhe motuhake e hoko ana i ngā kawhe taketake kotahi te nuinga o te wā e pai ake ana ki ngā whiringa putea tātari PLA. Mā te mata ka taea e ngā kaihoko te kite i te rahi o te hurihanga, ā, mā te kore o te reka pepa ka tiakina ngā kakara putiputi ngawari.
Ngā Pēke Pute Wai Matao Arumoni
Me tunu kia 12 ki te 24 hāora te nui o te wai hei hanga i te pia matao. He maha ngā wā ka ngohengohe, ka totohu, ka pakū rānei ngā tātari pepa i te wā e tangohia ana i raro i te taumaha nui o te wai.

Te Tapahi Hurihuri me te Taumahatanga Tapa
Hono atu ki ngā kaitahuri pēnei i aPēke tī kawhe Tonchante tuku ana i te tapahi tika me ngā roera whānui ritenga hei ārai i te whāiti o ngā taha i runga i ngā mīhini tākai aunoa.
Ngā Pātai Auau
He pai ake te rauemi tātari PLA i te pepa tuku iho?
Kei runga i ōu kaupapa matua. Mō ngā kawhe tunu motuhake he mea nui te waikawa ngawari, he pai ake te PLA nā te mea kāore e tāpirihia he reka pepa, ā, he kaha mākū teitei. Mō te kawhe hokohoko e aro ana ki te utu mata, he iti ake te utu o te pepa.
Ka taea e mātou te whakamahi i ngā rōra kore-whatu PLA i runga i ā mātou mīhini tākai o nāianei?
Āe. Heoi, me whakarerekē pea e koe ō tautuhinga mā te whakaheke i te pāmahana o te kauae hiri-wera mā te 15°C ki te 25°C ki te whakarite ki te Polypropylene, mā te neke rānei ki ngā wae hiri ultrasonic.
He aha i ētahi wā ka reka ai te pepa Kraft kāore i mā, he rite ki te rakau i te wā e hanga pia ana?
Ka mau tonu ngā lignin rakau tūturu i roto i te pepa kāore i whakama. Ka horoia ēnei matū e te wai wera ki roto i te kapu, ka puta he reka kātene, he reka rakau rānei. Ka whakaitihia tēnei e te pepa kua whakama ki te hāora, engari ka whakakorea katoatia e te mata hangai/PLA.
He aha te take e turuturu ai te puehu kawhe i te tuitui o raro?
Ko te nuinga o te wā ka puta mai ngā pakaru o te tuitui i te rerekētanga o te pāmahana o te kauae hiri, i te hononga ngoikore rānei o ngā muka i roto i te papanga kore-whatu iti te kounga. Ka wera rawa ngā muka PLA angiangi i te wera nui, engari ka kore e tino honoa ngā muka PLA i te wera nui.
Kia pēhea te roa o te oranga o ngā taonga PLA mata i roto i te whare putunga?
Mena ka rongoatia i raro i te 30°C me raro i te 60% te haumākū whanaunga, ā, kāore e pā ki te rā tika, ka mau tonu te hanganga me te kaha o ngā rōra kore-whatu PLA kāore anō kia whakatuwheratia mō te 12 ki te 18 marama.
Ngā Whakaaro Whakamutunga mō ngā Rōpū Hoko
He wero tonu te whakataurite i te mahi tango, te tere o te raina, ngā utu rauemi, me ngā herenga taiao i roto i ngā takai kawhe. I mua, he pono te mahi a ngā mea kore-whatu hangai, engari kei te tere te neke o te umanga ki ngā huarahi hou.
Ko ngā rauemi koiora pēnei i te PLA kore-whatu ka whakakī i te āputa mahi—e tuku ana i te kaha hanganga, te tango ma, me te tere me te āheinga ki te whakawairakau ahumahi kua whakamanahia.
Me hiahia koe ki tētahi tauira o ngā rakau rōra hei whakamātautau?
Whakamātauria ngā rōra tauira i runga i ō mīhini whakakī tuturu i raro i ngā āhuatanga wheketere tūturu.
