Ua hoʻouna ʻia nā kauoha resin PVC SG5 a Chemdo e ka mea lawe nui ma ʻAukake 1.
Ma ʻAukake 1, 2022, ua lawe ʻia kahi kauoha resin PVC SG5 i kau ʻia e Leon, ke luna kūʻai aku o Chemdo, ma ka moku nui i ka manawa i koho ʻia a haʻalele iā Tianjin Port, Kina, e holo ana i Guayaquil, Ecuador. ʻO KEY OHANA HKG131 ka huakaʻi, ʻo ka manawa i manaʻo ʻia e hōʻea ai ʻo Kepakemapa 1. Manaʻolana mākou e holo pono nā mea āpau i ka wā e lawe ʻia ai a e loaʻa koke i nā mea kūʻai aku nā waiwai i ka hikiwawe loa. -
Hoʻomaka ke kūkulu ʻia ʻana o ka lumi hōʻikeʻike o Chemdo.
I ke kakahiaka o ʻAukake 4, 2022, ua hoʻomaka ʻo Chemdo e hoʻonani i ka lumi hōʻikeʻike o ka hui. Hana ʻia ka hōʻikeʻike i ka lāʻau paʻa e hōʻike i nā ʻano like ʻole o PVC, PP, PE, a pēlā aku. ʻO ia ke kuleana nui o ka hōʻike ʻana a me ka hōʻike ʻana i nā waiwai, a hiki ke pāʻani i ke kuleana o ka hoʻolaha a me ka hōʻike ʻana, a hoʻohana ʻia no ka hoʻolaha ola, ke kiʻi ʻana a me ka wehewehe ʻana ma ka ʻoihana media ponoʻī. Ke kakali nei e hoʻopau koke iā ia a lawe mai iā ʻoe i nā kaʻana like hou aku. -
Pehea e hiki ai iā ʻoe ke haʻi inā he polypropylene ka plastic?
ʻO kekahi o nā ala maʻalahi loa e hoʻāʻo ai i ka lapalapa ahi, ʻo ia ka ʻoki ʻana i kahi hāpana mai ka palakiko a hoʻā iā ia i loko o kahi pahu uahi. Hiki i ke kala o ka lapalapa, ke ʻala a me nā ʻano o ka puhi ʻana ke hāʻawi i kahi hōʻailona o ke ʻano o ka palakiko: 1. Polyethylene (PE) - Nā kulu, ʻala e like me ka ipukukui; 2. Polypropylene (PP) - Nā kulu, ʻala nui o ka ʻaila mīkini lepo a me nā leo lalo o ka ipukukui; 3. Polymethylmethacrylate (PMMA, "Perspex") - Nā pehu, nā ʻūlū, ʻala ʻono; 4. Polyamide a i ʻole "Nylon" (PA) - Lālama sooty, ʻala o nā marigolds; 5. Acrylonitrilebutadienestyrene (ABS) - ʻAʻole moakaka, lapalapa sooty, ʻala o nā marigolds; 6. Polyethylene foam (PE) - Nā kulu, ʻala o ka ipukukui -
Hoʻolauna ʻo Mars M Beans i ka ʻōpala pepa composite PLA biodegradable ma Kina.
I ka makahiki 2022, ua hoʻokuʻu ʻo Mars i ka kokoleka M&M mua i hoʻopili ʻia i loko o ka pepa hui palaho ma Kina. Hana ʻia ia me nā mea palaho e like me ka pepa a me ka PLA, e pani ana i ka ʻōpala palaki palupalu kuʻuna i ka wā ma mua. Ua hala ka ʻōpala iā GB/T. Ua hōʻoia ke ʻano hoʻoholo o 19277.1 ma lalo o nā kūlana composting ʻoihana, hiki iā ia ke palaho ma mua o 90% i loko o 6 mau mahina, a e lilo ia i wai ʻawaʻawa ʻole, carbon dioxide a me nā huahana ʻē aʻe ma hope o ka palaho ʻana. -
Ke kiʻekiʻe nei nā mea hoʻokuʻu aku o Kina i ka PVC i ka hapa mua o ka makahiki.
Wahi a nā helu helu dute hou loa, i Iune 2022, ʻo ka nui o ka pauka PVC maʻemaʻe i lawe ʻia mai e koʻu ʻāina he 29,900 tons, he piʻi ʻana o 35.47% mai ka mahina i hala a me ka piʻi ʻana o 23.21% i kēlā me kēia makahiki; i Iune 2022, ʻo ka nui o ka pauka PVC maʻemaʻe i lawe ʻia aku e koʻu ʻāina he 223,500 tons, ʻo ka emi ʻana o kēlā me kēia mahina he 16%, a ʻo ka piʻi ʻana o kēlā me kēia makahiki he 72.50%. Ua hoʻomau ka nui o ka lawe ʻana aku i kahi kiʻekiʻe, kahi i hōʻemi ai i ka lako nui ma ka mākeke kūloko i kekahi ʻano. -
He aha ka Polypropylene (PP)?
He thermoplastic paʻakikī, paʻa, a crystalline ka Polypropylene (PP). Hana ʻia ia mai ka monomer propene (a i ʻole propylene). ʻO kēia resin hydrocarbon linear ka polymer māmā loa ma waena o nā plastics waiwai āpau. Hiki mai ka PP ma ke ʻano he homopolymer a i ʻole he copolymer a hiki ke hoʻonui nui ʻia me nā mea hoʻohui. Loaʻa iā ia ka hoʻohana ʻana i loko o ka ʻōpala, kaʻa, nā waiwai mea kūʻai aku, nā lāʻau lapaʻau, nā kiʻiʻoniʻoni hoʻolei, a pēlā aku. Ua lilo ka PP i mea koho, ʻoiai ke ʻimi nei ʻoe i kahi polymer me ka ikaika kiʻekiʻe (e laʻa, vs Polyamide) i nā noi ʻenekinia a i ʻole ke ʻimi wale nei i ka pono kumukūʻai i nā ʻōmole hoʻoheheʻe puhi (vs. PET). -
He aha ka Polyethylene (PE)?
ʻO Polyethylene (PE), i ʻike ʻia hoʻi he polythene a i ʻole polyethene, ʻo ia kekahi o nā plastics i hoʻohana nui ʻia ma ka honua. ʻO ka maʻamau, he ʻano linear ko Polyethylene a ua ʻike ʻia he mau polymers hoʻohui. ʻO ka hoʻohana nui ʻana o kēia mau polymers synthetic i loko o ka ʻōpala. Hoʻohana pinepine ʻia ʻo Polyethelyne e hana i nā ʻeke plastic, nā ʻōmole, nā kiʻiʻoniʻoni plastic, nā ipu, a me nā geomembranes. Hiki ke hoʻomaopopo ʻia ua hana ʻia ma mua o 100 miliona tone o ka polyethene i kēlā me kēia makahiki no nā kumu kalepa a me nā ʻoihana. -
Ka nānā ʻana i ka hana o ka mākeke hoʻokuʻu aku PVC o koʻu ʻāina i ka hapa mua o 2022.
I ka hapa mua o 2022, ua piʻi ka mākeke hoʻokuʻu aku i ka PVC i kēlā me kēia makahiki. I ka hapaha mua, i hoʻopilikia ʻia e ka hoʻokele waiwai honua a me ke ahulau, ua hōʻike nā ʻoihana hoʻokuʻu aku kūloko he nui ua emi iki ke koi no nā disks waho. Eia nō naʻe, mai ka hoʻomaka ʻana o Mei, me ka hoʻomaikaʻi ʻana o ke kūlana ahulau a me kekahi mau hana i hoʻolauna ʻia e ke aupuni Kina e paipai i ka hoʻōla ʻana o ka hoʻokele waiwai, ua kiʻekiʻe ka nui o ka hana o nā ʻoihana hana PVC kūloko, ua mahana ka mākeke hoʻokuʻu aku PVC, a ua piʻi ka koi no nā disks waho. Hōʻike ka helu i kahi ʻano ulu, a ua hoʻomaikaʻi ʻia ka hana holoʻokoʻa o ka mākeke i hoʻohālikelike ʻia me ka wā ma mua. -
He aha ka PVC i hoʻohana ʻia no?
Hoʻohana ʻia ka polyvinyl chloride (PVC, a i ʻole vinyl) i nā ʻano hana like ʻole i loko o ke kūkulu ʻana a me ke kūkulu ʻana, ka mālama ola kino, nā mea uila, nā kaʻa a me nā ʻoihana ʻē aʻe, i nā huahana mai ka paipu a me ka ʻaoʻao, nā ʻeke koko a me nā paipu, i ka insulation uea a me ke kaula, nā ʻāpana ʻōnaehana makani a me nā mea hou aku. -
Hālāwai Kakahiaka o Chemdo ma Iulai 26.
I ke kakahiaka o Iulai 26, ua mālama ʻo Chemdo i kahi hālāwai hui. I ka hoʻomaka ʻana, ua hōʻike ka luna nui i kona mau manaʻo no ke kūlana waiwai o kēia manawa: ua emi ka hoʻokele waiwai o ka honua, ua kaumaha ka ʻoihana kālepa haole holoʻokoʻa, ke emi nei ke koi, a ke emi nei ke kumukūʻai ukana 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 ʻia i ka wā hikiwawe. A ua hoʻoholo i ke kumuhana o ke wikiō media hou o kēia pule: ka Great Depression ma ke kālepa haole. A laila ua kono ʻo ia i kekahi mau hoa hana e kaʻana like i nā nūhou hou loa, a ua koi hope i nā keʻena kālā a me nā palapala e mālama pono i nā palapala. -
Ke kokoke nei e hāʻawi ʻia aku ka papahana hoʻonui ethylene a me ka hoʻomaʻemaʻe miliona-tona 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 ma mua o 28 biliona yuan. A hiki i kēia manawa, ua hiki aku ka holomua o ke kūkulu ʻana i 98%. Ma hope o ka pau ʻana o ka papahana a hoʻokomo ʻia i ka hana, manaʻo ʻia e hoʻokele i nā ʻoihana downstream ma mua o 100 biliona yuan. E mālama ʻia ka Olefin Feedstock Diversification a me High-end Downstream Forum ma Sanya ma Iulai 27-28. Ma lalo o ke kūlana hou, e kūkākūkā ʻia ka hoʻomohala ʻana i nā papahana nui e like me PDH, a me ka ethane cracking, ke ʻano o nā ʻenehana hou e like me ka ʻaila maka pololei i nā olefins, a me ka hanauna hou o ka lanahu/methanol i nā olefins. -
MIT: Hana nā microparticles copolymer polylactic-glycolic acid i ka lāʻau pale "hoʻoikaika ponoʻī".
Ua hōʻike nā kānaka ʻepekema ma ka Massachusetts Institute of Technology (MIT) ma ka puke pai ʻo Science Advances i hala koke aku nei e hoʻomohala ana lākou i kahi lāʻau pale hoʻoikaika ponoʻī hoʻokahi. Ma hope o ka hoʻokomo ʻia ʻana o ka lāʻau pale i loko o ke kino o ke kanaka, hiki ke hoʻokuʻu ʻia i nā manawa he nui me ka ʻole o ka pono no ka pana hoʻoikaika. Manaʻo ʻia e hoʻohana ʻia ka lāʻau pale hou e kūʻē i nā maʻi mai ka measles a i Covid-19. Ua hōʻike ʻia ua hana ʻia kēia lāʻau pale hou me nā ʻāpana poly(lactic-co-glycolic acid) (PLGA). He hui polymer organic hana hiki ke hoʻohaumia ʻia ka PLGA, ʻaʻohe mea ʻawahia a he biocompatibility maikaʻi. Ua ʻae ʻia no ka hoʻohana ʻana i nā Implants, sutures, nā mea hoʻoponopono, a pēlā aku.
