1. Tirohanga o te mekameka ahumahi:
Ko te ingoa katoa o te waikawa polylactic he waikawa poly lactic, he waikawa poly lactic ranei.He rauemi polyester teitei i whiwhi i te polymerization ki te waikawa lactic, waikawa lactic dimer lactide hei monomer.No roto i te papanga rapoi teitei me nga ahuatanga o te kaupapa koiora me te whakaheke.I tenei wa, ko te waikawa polylactic he kirihou biodegradable me te ahumahi tino pakeke, te whakaputanga nui rawa atu me te tino whakamahia i te ao.Ko te whakarunga o te ahumahi waikawa polylactic ko nga momo rauemi mata katoa, penei i te witi, te huka, te huka huka, me etahi atu, ko te waenganui ko te whakarite i te waikawa polylactic, ko te whakararo ko te nuinga o te whakamahinga o te waikawa polylactic, tae atu ki te tiaki i te taiao. taputapu tepu, takai tiaki taiao, etc.
2. Ahumahi whakarunga
I tenei wa, ko nga rauemi mata o te ahumahi waikawa polylactic o te kainga ko te waikawa lactic, a ko te waikawa lactic te nuinga kua rite mai i te witi, te huka, te huka huka me etahi atu hua ahuwhenua.Na reira, ko te umanga whakatō kai e rangatira ana e te kānga ko te umanga whakarunga o te mekameka ahumahi waikawa polylactic.Mai i te tirohanga o te hua witi a Haina me te waahi whakato, ka eke te hua whakato witi a Haina ki te 272.55 miriona taranata i te 2021, me te nui o te tauine, me te waahi whakato kua pumau ki te 40-45 miriona heketea mo nga tau maha.Mai i te tuku witi mo te wa roa i Haina, ka taea te tumanako ka noho pumau tonu te tuku witi a muri ake nei.
Mo etahi atu rauemi mata ka taea te whakamahi ki te whakaputa waikawa lactic, penei i te huka me te huka pīti, ko te hua katoa o Haina i te tau 2021 he 15.662 miriona taranata, he iti ake i tera i nga tau o mua, engari kei te taumata noa.A kei te kaha hoki nga umanga huri noa i te ao ki te tirotiro i nga huarahi hou hei whakarite i te waikawa lactic, penei i te whakamahi i te puna huka i roto i nga muka rakau penei i te kakau witi me te otaota hei whakareri i te waikawa lactic, te tirotiro ranei i te tikanga whakamahi mewaro hei whakaputa waikawa lactic.I runga i te katoa, ko te tukunga o te ahumahi whakarunga o te waikawa polylactic ka noho pumau a meake nei.
3. Ahumahi waenga
I te mea he rawa biodegradable rawa, ka taea e te waikawa polylactic te whakamutu i nga rawa mata ki roto i te punaha whakaora rawa me te punaha tukurua, kei a ia nga painga karekau o nga rawa hinu.Na reira, kei te piki haere te kai o te waikawa polylactic i te maakete o-whare.Ko te kai o te kainga i te tau 2021 ko te 48071.9 tone, he pikinga 40% ia tau.
Na te iti o te hanga o te waikawa polylactic i Haina, ko te nui o te kawemai o te waikawa polylactic i Haina he nui ake i te rahinga kaweake.I nga tau tata nei, kua piki tere te nui o te kawemai o te waikawa polylactic na te hiahia o te kainga.I te 2021, ko te kawemai o te waikawa polylactic i tae ki te 25294.9 tone.Ko te kaweake o te waikawa polylactic i tino ahu whakamua i te tau 2021, kua eke ki te 6205.5 tone, he pikinga tau-a-tau o 117%.
Ripoata e pa ana: purongo mo te tātaritanga ahua whanaketanga me te matapae tirohanga mo te whanaketanga o te ahumahi hua waikawa polylactic o Haina mai i te 2022 ki te 2028 i tukuna e Zhiyan consulting
4. Ahumahi whakararo
I roto i nga tono o raro, kua whakamahia te waikawa polylactic i roto i nga mara maha me tona ahurei koiora me te koiora.I tenei wa, kua whakamahia nuitia i roto i te kohinga taumata whakapiri kai, te taputapu tepu, te putea putea kiriata me etahi atu hua me nga mara.Hei tauira, ko te kiriata kirihou ahuwhenua i hangaia mai i te waikawa polylactic ka taea te tino whakaheke me te ngaro i muri i te kotinga o nga hua, kaore e whakaiti i te ihirangi wai me te hua o te oneone, engari ka karo ano i nga utu mahi me nga utu mahi e hiahiatia ana mo te whakaora kiriata kirihou, ko te ia whānui o te whanaketanga o te kiriata kirihou i Haina i roto i te heke mai.Ko te waahi e hipokina ana e te kiriata kirihou i Haina e tata ana ki te 18000 heketea, a ko te whakamahinga o te kiriata kirihou i te 2020 he 1357000 tons.Kia rongonuihia te kiriata kirihou whakaheke, he waahi nui te ahumahi waikawa polylactic mo te whanaketanga a meake nei.
