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. , -
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). -
He aha ka Polyethylene (PE)?
ʻO Polyethylene (PE) , i ʻike ʻia he polythene a i ʻole polyethene, kekahi o nā plastics i hoʻohana pinepine ʻia ma ka honua. ʻO ka polyethylenes he ʻano laina laina a ʻike ʻia he polymers hoʻohui. ʻO ka hoʻohana mua ʻana o kēia mau polymers synthetic i loko o ka ʻeke. Hoʻohana pinepine ʻia ka Polyethelyne e hana i nā ʻeke plastik, nā ʻōmole, nā kiʻiʻoniʻoni plastik, nā ipu, a me nā geomembranes. Hiki ke hoʻomaopopo ʻia ʻoi aku ma mua o 100 miliona tonnes o ka polyethene i hana ʻia i kēlā me kēia makahiki no nā hana ʻoihana a me nā ʻoihana. -
Ka ʻikepili o ka hana ʻana o ka mākeke kūʻai PVC o koʻu ʻāina i ka hapa mua o 2022.
I ka hapa mua o 2022, ua hoʻonui ka mākeke PVC export i kēlā me kēia makahiki. I ka hapaha mua, i hoʻopilikia ʻia e ka hoʻokele waiwai o ka honua a me ka maʻi ahulau, ua hōʻike ka nui o nā ʻoihana kūʻai kūloko i ka emi ʻana o ka noi no nā disks waho. Eia nō naʻe, mai ka hoʻomaka ʻana o Mei, me ka hoʻomaikaʻi ʻana i ke kūlana maʻi maʻi a me nā ʻano hana i hoʻolauna ʻia e ke aupuni Kina e paipai i ka hoʻihoʻi ʻana i ka hoʻokele waiwai, ua kiʻekiʻe ka nui o ka hana o nā ʻoihana hana PVC kūloko, ua mahana ka mākeke PVC export. , a ua hoʻonui ʻia ke koi no nā disks waho. Hōʻike ka helu i kahi ulu ulu, a ua hoʻomaikaʻi ka hana holoʻokoʻa o ka mākeke i ka wā ma mua. -
He aha ka PVC e hoʻohana ai?
Hoʻohana ʻia ka polyvinyl chloride maʻemaʻe (PVC, a i ʻole vinyl) i nā noi like ʻole i ka hale a me ke kūkulu ʻana, mālama ola kino, uila, kaʻa a me nā ʻāpana ʻē aʻe, i nā huahana mai ka paipa a me ka ʻaoʻao, nā ʻeke koko a me nā paipu, i ka uea a ka hoʻokuʻu ʻana i ke kaula, nā ʻōnaehana pale makani a me nā mea hou aku. , -
Hui Kakahiaka o Chemdo ma ka la 26 o Iulai.
Ma ke kakahiaka o Iulai 26, ua mālama ʻo Chemdo i kahi hālāwai hui. I ka hoʻomaka ʻana, ua hōʻike ka luna nui i kona manaʻo e pili ana i ke kūlana hoʻokele waiwai o kēia manawa: ke emi nei ka hoʻokele waiwai honua, ke kaumaha ka ʻoihana kalepa holoʻokoʻa o nā ʻāina ʻē, ke emi nei ke koi, a ke hāʻule nei ke kumukūʻai o ke kai. A e hoʻomanaʻo i nā limahana i ka hopena o Iulai, aia kekahi mau mea pilikino e pono e hoʻoponopono ʻia, hiki ke hoʻonohonoho koke ʻia. A ua hoʻoholo i ke kumumanaʻo o ka wikiō media hou o kēia pule: ʻo ka Great Depression i ke kālepa haole. A laila, kono ʻo ia i kekahi mau hoa hana e kaʻana like i nā nūhou hou loa, a ua koi ʻo ia i nā keʻena kālā a me nā palapala e mālama pono i nā palapala. , -
Ua kokoke e hāʻawi ʻia ka pāhana ethylene miliona miliona a me ka hoʻomaʻemaʻe ʻana o Hainan Refinery.
Aia ka Hainan Refining and Chemical Ethylene Project a me ka Refining Reconstruction and Expansion Project ma Yangpu Economic Development Zone, me ka huina kālā he 28 billion yuan. A hiki i kēia manawa, ua hōʻea ka holomua holoʻokoʻa i 98%. Ma hope o ka pau ʻana o ka papahana a hoʻokomo ʻia i loko o ka hana, manaʻo ʻia e hoʻokele ʻoi aku ma mua o 100 biliona yuan o nā ʻoihana o lalo.

Ua hōʻike ʻia ua hana ʻia kēia kano hou me nā ʻāpana poly(lactic-co-glycolic acid) (PLGA). ʻO ka PLGA kahi mea hoʻoheheʻe polymer organic compound, ʻaʻohe mea ʻawaʻawa a loaʻa ka biocompatibility maikaʻi. Ua ʻae ʻia no ka hoʻohana ʻana i nā Implants, sutures, repair materials, etc -
ʻO Yuneng Chemical Company: ʻO ka hana ʻoihana mua o ka polyethylene sprayable!
I kēia mau lā, ua hoʻopuka maikaʻi ka LLDPE o ka Polyolefin Center o Yuneng Chemical Company i ka DFDA-7042S, kahi huahana polyethylene sprayable. Ua hoʻomaopopo ʻia ʻo ka huahana polyethylene sprayable he huahana i loaʻa mai ka hoʻomohala wikiwiki ʻana o ka ʻenehana hoʻoponopono lalo. ʻO ka mea polyethylene kūikawā me ka hoʻoulu ʻana i ka hana ma luna o ka ʻili e hoʻonā i ka pilikia o ka hana kala ʻana o ka polyethylene a loaʻa ke aniani kiʻekiʻe. Hiki ke hoʻohana ʻia ka huahana i nā māla hoʻonaninani a me ka pale, kūpono i nā huahana o nā keiki, nā loko o ka kaʻa, nā mea hoʻopihapiha, a me nā pahu mālama ʻoihana nui a me nā mahiʻai, nā mea pāʻani, nā kiaʻi alanui, a me nā mea ʻē aʻe, a he nui ka manaʻo o ka mākeke. , -
ʻO Petronas 1.65 miliona tons o polyolefin e kokoke ana e hoʻi i ka mākeke ʻAsia!
Wahi a ka nūhou hou loa, ua hoʻomaka hou ʻo Pengerang ma Johor Bahru, Malaysia i kāna 350,000-ton/makahiki linear low-density polyethylene (LLDPE) unit ma Iulai 4, akā hiki i ka ʻāpana ke lawe i kahi manawa e loaʻa ai ka hana paʻa. Ma waho aʻe, ʻo kāna ʻenehana Spheripol 450,000 tons / makahiki polypropylene (PP) mea kanu, 400,000 tons / makahiki kiʻekiʻe polyethylene (HDPE) mea kanu a me Spherizone ʻenehana 450,000 tons / makahiki polypropylene (PP) mea kanu e manaʻo ʻia e hoʻonui ʻia mai kēia mahina e hoʻomaka hou. Wahi a Argus, ʻo ke kumukūʻai o LLDPE ma Asia Hikina Hema me ka ʻauhau ʻole ma Iulai 1 ʻo US $1360-1380/ton CFR, a ʻo ke kumu kūʻai o ke kiʻi uea PP ma Asia Hikina Hema ma Iulai 1 he US $1270-1300/ton CFR me ka ʻauhau ʻole. .
