He aha ka HDPE i hoʻohana ʻia no?
Hoʻohana ʻia ʻo HDPE i nā huahana a me nā ʻeke e like me nā hue waiu, nā ʻōmole detergent, nā pahu margarine, nā ipu ʻōpala a me nā paipu wai.I loko o nā paipu ʻokoʻa ka lōʻihi, hoʻohana ʻia ʻo HDPE ma ke ʻano he pani no nā pahu pahu pahu pahu i hoʻolako ʻia no nā kumu kumu ʻelua.ʻO ka mea hoʻokahi, ʻoi aku ka palekana ma mua o nā paipu pepa i hoʻolako ʻia no ka mea inā hana hewa ka pūpū a pahū i loko o kahi paipu HDPE, ʻaʻole e nahā ka paipu.ʻO ke kumu ʻelua, ʻo ia ka mea hiki ke hoʻohana hou ʻia e hiki ai i nā mea hoʻolālā ke hana i nā pahu mortar pana.ʻAʻole ʻae ka poʻe Pyrotechnic i ka hoʻohana ʻana i ka paipu PVC i loko o nā paipu mortar no ka mea ʻo ia ka mea e ʻāhaʻi, e hoʻouna ana i nā ʻāpana o ka plastic i nā mea nānā aku, ʻaʻole e hōʻike ʻia i nā hihi-X.ʻ -
Ua lilo ke kāleka ʻōmaʻomaʻo PLA i mea hoʻoponopono hoʻomau kaulana no ka ʻoihana kālā.
ʻOi aku ka nui o ka plastic no ka hana ʻana i nā kāleka panakō i kēlā me kēia makahiki, a me ka ulu ʻana o nā hopohopo kaiapuni, ua hoʻomohala ʻo Thales, kahi alakaʻi i ka palekana ʻenehana kiʻekiʻe.No ka laʻana, he kāleka i hana ʻia me 85% polylactic acid (PLA), i loaʻa mai ka kulina;ʻO kekahi ala hou e hoʻohana ai i ka ʻiʻo mai nā hana hoʻomaʻemaʻe kahakai ma o ka hui pū ʻana me ka hui kaiapuni ʻo Parley for the Oceans.ʻOhi ʻia nā ʻōpala palaka - "Ocean Plastic®" ma ke ʻano he mea maka no ka hana ʻana i nā kāleka;Aia kekahi koho no nā kāleka PVC i hana hou ʻia i hana ʻia mai ka palaka ʻōpala mai ka ʻoihana paʻi a me ka ʻoihana paʻi e hōʻemi i ka hoʻohana ʻana i ka plastik hou.ʻ -
ʻO kahi hōʻike pōkole o ka paʻi pvc resin a Kina i ka ʻikepili mai Ianuali a Iune.
Mai Ianuali a Iune 2022, ua lawe mai koʻu ʻāina i ka huina o 37,600 tons o ka resin paste, kahi emi o 23% i hoʻohālikelike ʻia me ka manawa like o ka makahiki i hala, a lawe aku i ka huina o 46,800 tons o ka resin paste, kahi piʻi o 53.16% i hoʻohālikelike ʻia me ka manawa like i ka makahiki i hala.I ka hapa mua o ka makahiki, koe wale no nā ʻoihana hoʻokahi i pani ʻia no ka mālama ʻana, ua mau ka ukana hana o ka hale paʻi resin resin i kahi kiʻekiʻe, ua lawa ka lako o nā waiwai, a ua hoʻomau ka mākeke.Ua ʻimi ikaika nā mea hana i nā kauoha e hoʻokuʻu aku i waho e hoʻopau i nā paio mākeke kūloko, a ua hoʻonui nui ʻia ka nui o ka lawe ʻana aku. -
Pehea ʻoe e ʻike ai inā he polypropylene ka plastic?
ʻO kekahi o nā ala maʻalahi e hoʻokō ai i ka hoʻāʻo ʻana i ka lapalapa ʻana ma ke ʻoki ʻana i kahi laʻana mai ka plastic a hoʻā ʻia i loko o kahi kīʻaha hū.ʻO ke kala o ka lapalapa, ka ʻala a me nā hiʻohiʻona o ke ahi e hiki ke hōʻike i ke ʻano o ka plastic: 1. Polyethylene (PE) - Drips, pilau e like me ke kukui; 2. Polypropylene (PP) - Drips, pilau ka hapa nui o ka ʻaila ʻenekini lepo a me ke kani. o ka ipukukui; 3. Polymethylmethacrylate (PMMA, “Perspex”) – Bubbles, crackles, ʻala ʻala ʻono; 4. Polyamide a i ʻole “Nylon” (PA) – Soty flame, pilau o marigolds; 5. Acrylonitrilebutadienestyrene (ABS) – ʻAʻole maopopo, lapalapa ahi, ʻala o nā marigold; 6. Polyethylene foam (PE) – kulu, ʻala o ke kukui. -
Hoʻokuʻu ʻo Mars M Beans i ka paʻi pepa PLA composite biodegradable ma Kina.
I ka makahiki 2022, ua hoʻolaha ʻo Mars i ka M&M's chocolate mua i hoʻopaʻa ʻia i loko o ka pepa composite degradable ma Kina.Hana ʻia ia i nā mea hoʻoheheʻe ʻia e like me ka pepa a me ka PLA, e hoʻololi ana i ka ʻōpala palaka palupalu maʻamau i ka wā ma mua.Ua hala ka pahu i ka GB / T Ua hōʻoia ke ʻano hoʻoholo o 19277.1 ma lalo o nā kūlana composting ʻoihana, hiki ke hoʻohaʻahaʻa ʻoi aku ma mua o 90% i loko o 6 mau mahina, a lilo ia i wai waiʻona non-biologically, carbon dioxide a me nā huahana ʻē aʻe ma hope o ka degradation.ʻ -
Noho kiʻekiʻe nā mea hoʻopuka PVC o Kina i ka hapa mua o ka makahiki.
Wahi a nā helu kuʻuna hou loa, i Iune 2022, ʻo ka nui o ka lawe ʻana mai o ka pauka PVC maʻemaʻe o koʻu ʻāina he 29,900 tons, he piʻi o 35.47% mai ka mahina i hala a me ka piʻi ʻana o ka makahiki he 23.21%;i Iune 2022, he 223,500 tons ka nui o ka pauka maʻemaʻe PVC o koʻu ʻāina, ʻo ka emi ʻana o ka mahina he 16%, a ʻo ka piʻi ʻana o ka makahiki he 72.50%.Ua hoʻomau ka nui o ka hoʻokuʻu aku i kahi kiʻekiʻe kiʻekiʻe, kahi i hoʻohaʻahaʻa i ka hoʻolako nui ʻana i ka mākeke kūloko i kekahi ʻano. -
He aha ka Polypropylene (PP)?
ʻO ka Polypropylene (PP) he mea ʻoluʻolu, ʻoʻoleʻa, a me ka crystalline thermoplastic.Hana ʻia ia mai ka propene (a i ʻole propylene) monomer.ʻO kēia linear hydrocarbon resin ka polymer māmā loa ma waena o nā plastic commodity āpau.Hele mai ʻo PP ma ke ʻano he homopolymer a i ʻole copolymer a hiki ke hoʻonui nui ʻia me nā mea hoʻohui.Loaʻa iā ia ka hoʻohana ʻana i ka ʻeke, automotive, consumer good, medical, cast films, etc. Ua lilo ʻo PP i mea waiwai i koho ʻia, ʻoiai ke ʻimi nei ʻoe i kahi polymer me ka ikaika kiʻekiʻe (eg, vs Polyamide) i nā noi ʻenekinia a i ʻole e ʻimi wale ana. ʻoi aku ka maikaʻi o ke kumukūʻai ma nā ʻōmole puhi puhi (vs. PET). -
