I te marama hou o ngā tau e rua kua pahure ake nei, kua tino piki haere te mākete kopare, ā, kua rerekē te hiahia o te mākete ināianei. Ko te putea ngohengohe e whai ake nei i roto i te roa o te mekameka me te rahinga o raro e akiaki ana i ngā kamupene ki te putea i ngā hua kopare ki roto i te momo. He keke nui rawa atu tēnei, ā, kei te nui haere tonu. Mō te putea ngohengohe, kua ki tonu te heke mai i ngā hiahia pakihi me ngā wero mō ngā umanga me ngā whai wāhitanga pakihi mutunga kore. I te aroaro o te āhuatanga mākete pai, ka haere tonu ngā putea ngohengohe ki te whakapai ake i te taumata whakaputa me te kounga hua kia whiwhi ai i tētahi tūranga nui i roto i te mākete.
Ngā āhuatanga me te hanganga o te putea kopare
I ēnei rā, kua noho hei momo āhua ngā kopare kanohi kounga teitei. Haunga te whakaatu i te mahi me te kakano pai i runga i ngā putea takai pepa konumohe, me roa ake te wā e mau ai. Ko te nuinga o ngā kopare he roa ake i te 12 marama te roa, ko ētahi he 36 marama te roa. Nā te roa o te wā e mau ai, ko ngā whakaritenga matua mō te takai ko: te ātete hau me ngā āhuatanga ārai teitei. I runga i ngā āhuatanga kai o te kopare tonu me ngā whakaritenga o tōna ake wā e mau ai, ka whakatauhia te hanganga rauemi me ngā whakaritenga o te putea takai kopare.
I tēnei wā, ko ngā hanganga matua o te nuinga o ngā kopare ko: PET/AL/PE, PET/AL/PET/PE, PET/VMPET/PE, BOPP/VMPET/PE, BOPP/AL/PE, MAT-OPP/VMPET/PE, MAT-OPP /AL/PE me ētahi atu. Mai i te tirohanga o te hanganga rauemi matua, ko te kiriata konumohe me te kiriata konumohe parakore te nuinga o te wā e whakamahia ana i roto i te hanganga takai. Ki te whakatauritea ki te whakakikorua konumohe, he pai te kakano whakarewa o te konumohe parakore, he hiriwa mā, ā, he āhuatanga ārai-kanapa; he ngohengohe te konganuku konumohe, ā, ka taea te whakarite i ngā hua me ngā rauemi hiato me ngā matotoru rerekē kia rite ki ngā whakaritenga, kia rite ki te whai i ngā hua kounga teitei mō te kakano taumaha, kia pai ake ai te whakaata o ngā kopare kounga teitei mai i te takai. Nā tēnei, ko ngā whakaritenga mahi taketake o te putea takai kopare mai i te tīmatanga ki te tono kounga teitei mō te pikinga o te mahi me te kakano i te wā kotahi kua whai wāhi ki te whakawhiti o te putea kopare mai i te putea whakakikorua konumohe ki te putea konumohe parakore. Ki te whakatauritea ki ngā whakapaipai papai o te mata, he mea nui ake ngā mahi rokiroki me te tiaki o te putea tākai. Engari ko te mea pono, he tokomaha te hunga e kore e aro ki tēnei.
Mai i te tātaritanga o ngā rauemi mata, e rua ngā momo o ngā putea tākai kopare whānui: ngā putea konumohe me ngā putea konumohe parakore. Ko te putea konumohe he mea pani kia ōrite te konumohe whakarewa parakore ki runga i te kiriata kirihou i raro i te āhua korehau pāmahana teitei. Ka whakakotahihia ngā putea konumohe parakore ki te pepa konumohe me te kiriata kirihou, koinei te hua o te mekameka ahumahi konumohe, ka taea te whakapai ake i ngā āhuatanga ārai, ngā āhuatanga hiri, te pupuri kakara, me ngā āhuatanga tiaki o ngā kirihou. Arā, he pai ake ngā putea kopare konumohe parakore mō ngā whakaritenga mākete o nāianei mō ngā putea tākai kopare.
Ngā pūwāhi whakahaere whakaputa o ngā putea tākai kopare
1. Te tā
Mai i ngā whakaritenga o te mākete o nāianei me ngā tirohanga a te kaihoko, ko te kopare te mea nui ko ngā hua reo-rahi me ngā hua teitei, nō reira, ko te whakapaipai taketake rawa atu me whai whakaritenga rerekē pērā i te kai noa me te takai o ia rā. He mea tika kia mārama ki ngā tumanakohanga hinengaro a te kaihoko. Nō reira, mō te tānga, hei tauira, ko te tānga PET, ka teitei ake te tika o te tānga me ngā whakaritenga tae i ngā whakaritenga takai kē atu. Mena ko te paerewa paerewa ā-motu he 0.2mm, ko te tūranga tuarua o ngā tānga putea takai kopare me tutuki i tēnei paerewa tānga kia pai ake ai te whakatutuki i ngā whakaritenga a ngā kaihoko me ngā hiahia o te kaihoko. Mō ngā rerekētanga tae, he tino pakari ake, he tino taipitopito ake hoki ngā kaihoko o ngā takai kopare i ngā kamupene kai noa. Nō reira, i roto i te hononga tā, me aro nui ngā umanga e hanga ana i ngā takai kopare ki te whakahaere. He pono, he nui ake ngā whakaritenga mō ngā papa tānga kia tutuki ai ngā whakaritenga teitei mō te tānga.
2. Pūhui
E toru ngā āhuatanga matua o te whakahaere i te hiato: ngā kita hiato, ngā toenga whakarewa hiato, ngā ira rinena hiato, me ngā mirumiru hau rerekē. Ko ēnei āhuatanga e toru he mea nui e pā ana ki te tere o te hua kua oti o ngā putea tākai kopare kanohi.
Ngā kita whakakotahi
Mai i te hanganga o runga ake nei, ka kitea ko te nuinga o te putea tākai kopare he mea hanga mai i te konumohe parakore. Ka whakatōngia te konumohe parakore ki roto i tētahi pepa kiriuhi angiangi rawa mai i te konganuku parakore. Ko te matotoru o te whakamahinga taketake kei waenga i te 6.5 ~ 7 & mu; He tino ngāwari te kiriuhi konumohe parakore ki te whakaputa i ngā kita, i ngā hekenga rānei i te wā o te tukanga whakakotahi, inā koa mō ngā mīhini whakakotahi aunoa. I te wā o te whakakotahi, nā te koretake o te here aunoa i te matua pepa, he ngāwari te kore taurite, ā, he tino ngāwari te waea tika i muri i te whakakotahitanga o te kiriata konumohe, tae noa ki ngā kita. Hei whakautu ki ngā kita, i tētahi taha, ka taea e tātou te whakatika i ngā rongoā e whai ake nei hei whakaiti i te ngaronga i puta mai i ngā kita. Ka pumau te kāpia whakakotahi ki tētahi āhua, he huarahi tēnei ki te huri anō i runga i te Whakaiti, pērā i te whakamahi i ngā matua pepa nui ake hei whakapai ake i te pānga kohikohinga.
toenga whakarewa hiato
Nā te mea he konumohe, he konumohe parakore rānei te nuinga o ngā takai kopare, mō te whakakotahitanga, he konumohe, he konumohe parakore rānei, kāore e pai mō te whakakorikori o te whakarewa. He mea whakamate ki te whakakorikori o ngā whakarewa. E mārama ana te kī i roto i te paerewa GB/T10004-2008 "Kiriata Whakakotahi Kirihou, Tangohanga Whakakotahi Whakamaroke Pēke": Kāore tēnei paerewa e tika mō te kiriata kirihou me ngā putea i hangaia mai i ngā rauemi kirihou me ngā rōpū pepa, ngā whakakotahitanga pepa konumohe rānei. Heoi, ko ngā umanga takai kopare o nāianei me te nuinga o ngā kamupene kei raro hoki i te paerewa ā-motu. Mō ngā putea pepa konumohe, me whai whakaaro pohehe tēnei paerewa. Ko te tikanga, kāore he whakaritenga mārama o te paerewa ā-motu. Engari me whakahaere tonu e tātou ngā toenga whakarewa i roto i te hanga tūturu, he mea tino nui tēnei. Mō te wheako, ka taea te whakapai ake i te kōwhiringa o te kāpia me te tere o te mīhini hanga me te pāmahana o te oumu, me te nui o te tukunga taputapu. Ko te tikanga, i roto i tēnei whakaaro, me tātari me te whakapai ake i ngā taputapu motuhake me ngā taiao motuhake.
Ngā rārangi whakakotahi, ngā mirumiru
He tino hononga anō hoki tēnei raruraru ki te konumohe parakore, inā koa ka nui ake te tūponotanga o te hanganga o te PET/Al hiato. Ka kohikohia he maha ngā ira tioata ki te mata o te mata hiato, te āhuatanga rānei o te ira mirumiru. He maha ngā take matua: ngā rauemi papa: kāore i te pai te mata o te papa, ā, he ngāwari ki te whakaputa i te mate whakangote me ngā mirumiru; he take nui anō hoki te nui rawa o te ira tioata o te papa PE. Ka puta anō hoki ngā raruraru rite i te wā e whakakotahi ana ngā matūriki matotoru. Mō te mahi a te mīhini: Ko te kore e ranea te mimiti o te whakarewa, te kore e ranea te pēhanga hiato, te aukati i te mata o runga o te kāpia, ngā mea ke, me ētahi atu, ka puta anō hoki ngā āhuatanga rite.
3, te hanga putea
Ko te pūwāhi whakahaere o te tukanga kua oti te nuinga e whakawhirinaki ana ki te papatahi o te putea me te kaha me te āhua o te taha. I roto i te tukanga hua kua oti, he uaua ake te hopu i te papatahi me te āhua. Nā te mea ko tōna taumata hangarau whakamutunga e whakatauhia ana e te mahi mīhini, ngā taputapu me ngā tikanga whakahaere a ngā kaimahi, he tino ngāwari te waru i ngā putea i te tukanga kua oti, me ngā hapa pēnei i ngā taha nui me ngā taha iti. Mō te putea kopare tino pakari, kāore e whakaaetia ēnei. Hei whakautu i tēnei raruraru, he pai ake te whakahaere i te āhuatanga o te waru mai i ngā āhuatanga 5S tino taketake. Hei whakahaere taiao awheawhe tino taketake, me whakarite kia ma te mīhini, kia kore he tinana ke i runga i te mīhini, me whakarite kia mahi noa me te maeneene. He taurangi whakaputa taketake tēnei. He mea tika kia haere ki te whakawhanake i tētahi tikanga pai. Mō te āhua, he whakaritenga whānui mō ngā whakaritenga o te taha me te kaha o te taha. Me angiangi ake te tono o ngā raina, ā, me whakamahi te maripi papatahi hei pēhi i te taha. I roto i tēnei tukanga, he whakamātautau pai hoki mō ngā kaiwhakahaere o te mīhini.
4. Te kōwhiringa o ngā papa me ngā rauemi āwhina
Me whiriwhiri te PE e whakamahia ana i roto i te kopare i ngā rauemi PE whai hua mō te ātete paru, te ātete wai, me te ātete waikawa. Mai i te tirohanga a ngā tikanga whakamahi a te kaihoko, me ngāwari hoki te haehae i ngā rauemi PE, ā, mō ngā whakaritenga āhua o te PE tonu, ko ngā pūwāhi tioata, ko ngā pūwāhi tioata tōna pūwāhi whakahaere whakaputa matua, ki te kore ka maha ngā hapa i roto i tā mātou tukanga whakakotahitanga. Ko te wai o te kopare he nui te ōrau o te waipiro, nō reira me whakamahi te kāpia e whiriwhiria ana e mātou i te ātete pāpāho.
hei whakamutunga
I te nuinga o te wā, me aro nui te pēke tākai kopare ki ngā taipitopito maha i te wā o te tukanga whakaputa, nā te mea he rerekē ōna whakaritenga i ngā tākai noa, he nui te auau mate o ngā kamupene pēke ngohengohe. Nō reira, me tino taipitopito ia tukanga, me te whakapiki tonu i te tere o ngā hua kua oti. Mā tēnei anake ka taea e te umanga tākai kopare te hopu i te whai wāhitanga i roto i te whakataetae mākete, kia kore ai e taea te hinga.
