He aha ka PVC e hoʻohana ai?
Hoʻohana ʻia ka polyvinyl chloride waiwai nui (PVC, a i ʻole vinyl) i nā ʻano hana like ʻole i ka hale a me ke kūkulu ʻana, mālama olakino, 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 me ka hoʻokaʻawale ʻana i ke kaula, nā ʻōnaehana pale makani a me nā mea hou aku. , -
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. E mālama ʻia ʻo Olefin Feedstock Diversification a 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 ka wā e hiki mai ana o nā ʻenehana hou e like me ka aila ʻaila pololei i nā olefins, a me ka hanauna hou o ka lanahu / methanol i olefins. , -
MIT: Hana nā microparticles polylactic-glycolic acid copolymer i ka lāʻau lapaʻau "hoʻonui iā ia iho".
Ua hōʻike nā kānaka ʻepekema ma Massachusetts Institute of Technology (MIT) i loko o ka puke moʻolelo Science Advances e hoʻomohala ana lākou i kahi kano hoʻoikaika kino hoʻokahi. Ma hope o ka hoʻokomo ʻia ʻana o ka lāʻau lapaʻau i loko o ke kino o ke kanaka, hiki ke hoʻokuʻu ʻia i nā manawa he nui me ka ʻole o ka pana booster. Manaʻo ʻia e hoʻohana ʻia ka lāʻau lapaʻau hou e kūʻē i nā maʻi mai ka maʻi maʻi a hiki i Covid-19. 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 ka loiloi a Argus, ʻo ke kumukūʻai o LLDPE ma Asia Hikina Hema me ka ʻauhau ʻole ma Iulai 1 he US$1360-1380/ton CFR, a ʻo ke kumu kūʻai o ka uwea PP ma Asia Hikina Hema ma Iulai 1 he US$1270-1300/ton CFR me ka ʻauhau ʻole. -
Ua hoʻololi ka cigarette i ka ʻeke plastik biodegradable ma India.
ʻO ka pāpā ʻana o India i 19 mau mea hoʻohana hoʻokahi i hoʻololi i kāna ʻoihana paka. Ma mua o Iulai 1, ua hoʻololi ka poʻe hana kikaki India i kā lākou ʻeke plastik maʻamau ma mua i ka ʻeke plastik biodegradable. Ua ʻōlelo ka Tobacco Institute of India (TII) ua hoʻololi ʻia ko lākou mau lālā a ua kūpono nā plastic biodegradable i hoʻohana ʻia i nā kūlana honua, a me ka maʻamau BIS i hoʻopuka hou ʻia. Ua ʻōlelo pū lākou e hoʻomaka ana ka biodegradation o nā plastic biodegradable i ka pilina me ka lepo a me ka biodegrades maoli i ka compost me ke koʻikoʻi ʻole o ka ʻohi ʻōpala paʻa a me nā ʻōnaehana hana hou. -
ʻO ka loiloi pōkole o ka hana ʻana o ka mākeke Calcium Carbide ma ka hapa mua o ka makahiki.
I ka hapa mua o 2022, ʻaʻole i hoʻomau ka mākeke calcium carbide kūloko i ke ʻano nui o ka fluctuation ma 2021. Ua kokoke ka mākeke holoʻokoʻa i ka laina kumu kūʻai, a ua kau ʻia i nā fluctuations a me nā hoʻoponopono ma muli o ka hopena o nā mea maka, ka lako a me ke koi, a me nā kūlana o lalo. I ka hapa mua o ka makahiki, ʻaʻohe hiki ke hoʻonui hou ʻia o nā mea kanu PVC carbide kūloko, a ua kaupalena ʻia ka piʻi ʻana o ka mākeke calcium carbide. He mea paʻakikī i nā ʻoihana chlor-alkali e kūʻai i ka calcium carbide e mālama i kahi ukana paʻa no ka manawa lōʻihi. -
Ua pahū ʻia ma kahi reactor PVC o kahi kanaka nunui petrochemical ma ka Hikina Waena!
Ua hoʻolaha ʻo Petkim petrochemical Turkish ma ke ahiahi o Iune 19, 2022, ua pahū ʻia ka mea kanu ʻo Aliaga. ua loaʻa ka pōʻino i loko o ka PVC reactor o ka hale hana, ʻaʻohe mea i ʻeha, ua hoʻomalu koke ʻia ke ahi, akā hiki ke hoʻopaʻa ʻia ka ʻāpana PVC no ka manawa pōkole ma muli o ka ulia. He hopena nui paha ka hanana ma ka mākeke wahi PVC o ʻEulopa. Ua hōʻike ʻia no ka mea ʻoi aku ka haʻahaʻa o ke kumukūʻai o PVC ma Kina ma mua o nā huahana kūloko o Turkey, a ʻoi aku ka kiʻekiʻe o ke kumukūʻai o PVC ma ʻEulopa ma mua o ko Tureke, ʻo ka hapa nui o nā huahana PVC a Petkim i kēia manawa ke lawe ʻia aku i ka mākeke ʻEulopa. -

Ua hoʻopuka ʻo Nanning Airport i ka "Nanning Airport Plastic Ban and Restriction Management Regulations" no ka hoʻolaha ʻana i ka hoʻokō ʻana i ka hoʻokele pollution plastic i loko o ke kahua mokulele. I kēia manawa, ua hoʻololi ʻia nā huahana plastic non-degradable me nā mea hiki ke hoʻohaumia ʻia i nā hale kūʻai, nā hale ʻaina, nā wahi hoʻomaha o ka poʻe kaʻa, nā wahi kaʻa a me nā wahi ʻē aʻe o ka hale terminal, a ua hoʻōki nā huakaʻi kaʻa i ka hāʻawi ʻana i nā mauʻu palaka non-degradable, nā lāʻau hoʻoulu, nā ʻeke ʻeke, hoʻohana i nā huahana degradable a i ʻole nā mea ʻē aʻe. E ʻike i ka "hoʻomaʻemaʻe ʻana" o nā huahana plastik hiki ʻole ke hoʻoemi ʻia, a "e ʻoluʻolu e komo mai" no nā mea ʻokoʻa e pili ana i ke kaiapuni. -
He aha ka PP resin?
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. ʻO ka polypropylene i ʻike ʻia he polypropene, he polymer thermoplastic i hoʻohana ʻia i nā ʻano noi like ʻole. Hana ʻia ia ma o ka polymerization ulu ʻana o ke kaulahao mai ka propylene monomer. No ka hui o polyolefins ka polypropylene a he ʻāpana crystalline a me ka polar ʻole. Ua like kona mau waiwai me ka polyethylene, akā ʻoi aku ka paʻakikī a ʻoi aku ka wela. He mea keʻokeʻo keʻokeʻo me ka mechanically a he kiʻekiʻe ke kū'ē kemika.
