Ngā tohu mātaurangawhakaaro ki te MODPE
1, kiriata MDOPE,arā, ko te tukanga MDO (tohatoha kotahi-ara) i hangaia e te kiriata polyethylene PE pakari teitei, he tino pakari, he mārama, he ātete ki te wero me te ātete ki te wera, ko ōna āhuatanga āhua me te kiriata BOPET he tino rite ki te kaha ki te whakatinana i te PE me te PE hiato, nā reira ka hangaia he 100% o te hanganga rauemi polyethylene o te takai ngāwari i roto i te hangarua, kāore e hiahiatia te tihore i ngā kirihou rerekē. I te wā e hangarua ana, kāore he take ki te tihore i ngā kirihou rerekē, ka tino whakaiti i te uaua o te tukanga. Ka pakaruhia e tēnei auahatanga ngā herenga o te takai ngāwari hiato tuku iho i hangaia mai i ngā rauemi rerekē e kore e taea te hangarua, ā, he peke whakamua nui tēnei i roto i te hangarau takai ngāwari.
E toru ngā raupapa o ngā kiriata MDOPE:
Raupapa momo whānui MDOPE-T,
Raupapa ārai-teitei MDOPE-E,
Raupapa ārai tino teitei MDOPE-S;
Nā te pai o te papatahi me te mahi tā, te pumau wera pai me te iti o te mimiti, ka taea te whakamahi i te kiriata MDOPE hei kiriata tā mō ngā putea hiri e waru-taha, ngā putea pūwero momi me ngā putea reti.
2. Ko te tohu GRS he tohu mō te Global Recycled Standard.
He paerewa ā-ao, tūao, he hua katoa tēnei, i hangaia hei whakarite kia tika te tapanga o ngā ihirangi hangarua o ngā hua, me te whakarite kia hangaia ngā hua i runga anō i ngā paerewa kawenga taiao me te pāpori.
He paerewa ā-ao, tūao, he hua katoa tēnei, i hangaia hei whakarite kia tika te tapanga o ngā ihirangi hangarua o ngā hua, ā, kia tutuki hoki i te tukanga whakaputa ngā paerewa kawenga taiao me te pāpori motuhake.
GRSPE (me te pe hangarua)
Mai i te tau 2022, kua whakahaerehia e Shanghai Xiangwei Packaging Co.,Ltd te rangahau mō te tānga o ngā putea mono-material ka taea te hangarua, ā, kua kohia e mātou he nui o ngā wheako me te tūranga pakari, hei kaiārahi i roto i te ahumahi i roto i tā rātou tono.
Ko te uauatanga matua o te hanga putea takitahi ko te hanga pēke, e hiahia ana kia mahi tahi ngā tukanga o muri mai. Me rerekē te pāmahana o te rauemi MDOPE ki te kiriata turanga kia pumau ai te hanga pēke.
Mō te tānga, me aro nui ki te tānga nui, te piri o te waituhi, te pānga whakamaroke (ngā toenga me te piri anō hoki). Te ōritetanga o ngā rauemi me te whakahaere i te kume.
I roto i te hanganga rauemi, me whakahaere te taumahatanga, te pāmahana whakamaroke, me te nui o te hau whakamaroke, he pai ake te whakamahi i te kāpia matotoru-teitei me te tukatuka kupenga pāpaku.
Ko te mahi hanga putea te taahiraa matua, ko te hanga putea he maimoatanga kore-piri ki te maripi hiri wera, ngana ki te whakaputa i te pāmahana iti me te pēhanga teitei;
I te hoko rauemi, me whakarite kia nui te rohe rerekētanga pāmahana i waenga i te ira rewa wera o te papanga me te rauemi turanga;
Whakahaerehia te kume o te rauemi e kukume ana i te wā e hanga ana i ngā putea, ko te iti ake ko te pai ake;
Whakatakotoria te taha kia whānui rawa atu, kia rite ki te poutū, ki te mea he pereti iti te putea, kia maha ngā rarangi e taea ana, kia kore ai e hikoi te kiriata rauemi he kuiti rawa;
Kaua e whakamahi i ngā putea reti ina whiriwhiria he reti pāmahana iti motuhake, kia kore ai e pakaru te pane o te reti.
I tēnei wā, e whakapono whānuitia ana te umanga he pai te ātete pāmahana o te kiriata MDOPE, he papatahi ake te momo putea, he ngāwari ki te whakahaere i te miro.
Me whiriwhiri te rauemi arai PE i runga i te āhuatanga motuhake, hei tauira, ki te hiahia koe ki ngā āhuatanga ārai pai, ka taea e koe te whiriwhiri i te EVOH-PE, te PE miraka rānei.
Mena kāore he whakaritenga motuhake, ka taea e koe te whiriwhiri i te LDPE e whakamahia whānuitia ana.!
NGĀ TOHUTOHU
1. Ngāna ki te whakamahi i te raina haehae ngāwari ina taea te tautoko e te whakapaunga a te kiritaki.
2. I mua i te whakaae i te ota (e ai ki ngā momo putea rerekē), me whakamārama ko te hanganga PE//PE o te tinana putea he kino ake i ētahi atu rauemi (ka taea e koe te tango i tētahi ataata hou o te momo putea rite hei whakamārama!) Ko te tinana o te hanganga PE//PE he iti ake te papatahi i ētahi atu rauemi (ka taea e koe te tango i te ataata hou o ngā putea rite hei whakaatu!
Ko te takai hangarua rauemi kotahi te mea tino rongonui, me mahi pai ngā umanga tā tae i ngā rahui hangarau, me whakamātau tuatahi i ngā wāhanga e rua e whai ake nei:
1、Tākai Hukapapa
Whakamahia te PE kume-kotahi hei utu mō te PET me te nairona BOPA hei hanga rauemi PE kotahi mō ngā takai tio, inā koa mō ngā takai tio kāore e hiahia ki te mahi ārai teitei.
Ka whakaitihia te ātete haehae mā te whakamahi i te PE hei utu mō te nairona, engari ka taea te whakatutuki i ngā whakaritenga o te takai tio, ā, ka taea e te nuinga o ngā kiritaki te whakaaro ki te whakamahi anō. Mēnā ka whakamahia te PE hei utu mō te PET, ka nui ake te utu. I te nuinga o te wā, ko te matotoru o te putea, ko te nui ake o te utu whakakapinga.
2、Te pāmahana noa me ngā hua tiaki wā poto
Ka taea e te umanga tā tae te tīmata mai i te pāmahana rūma, te whakapūtātanga poto i te takai hua, te mōhio tuatahi ki te rauemi me te tukanga, me te tatari kia pakari ake te rauemi.
I te wa ano, me aro atu ki te tukanga:
Te hanga i te takai rauemi kotahi, ko te iti o ngā taurangi ko te pai ake.
Hei tauira, ko te mīhini tā motuhake mō te tānga PE he tino pai te pānga, ka taea te whakahaere i te kume me te tino pai, he tino tika te tānga nui, ahakoa he hiki me te whakaheke i te tere, he whakarerekē rānei i te rōra, ka taea te whakahaere pai. Ko te kounga tā me te mangumangu DIC he 97% tata ki te taumata o te tā nairona.
Nō reira, i roto i te hanga takai hangarua rauemi kotahi, ngana ki te tohu i ngā taputapu hei tohunga ki te hanga, kaua e whakarerekē noa i te raina hanga kia mau tonu ai te tukanga me te whakanui ake i te whakahaere i te ngaronga. Hei tauira, he rerekē te rauemi PE i roto i te hanga putea, me ētahi atu rauemi. I tēnei wā, kaua e tuku i te rauemi kia urutau ki te mīhini hanga putea, engari me tuku i te mīhini hanga putea kia urutau ki te rauemi: ki te whakamātauria he puranga PE i te mīhini kotahi, he iti rawa te whai huatanga. I tetahi atu taha, mō te rangahau me te whakawhanaketanga o te mīhini hanga putea mō te takai rauemi PE kotahi, tae atu ki te pēhanga hiri wera, te nui o te whakahaere pāmahana hiri wera, me ētahi atu, ka taea te whakarite kia kore ai e wera rawa, e hē rānei te hiri.
