He aha ka huahana plastik?

Hoʻohana nui ʻia nā plastik a he mau mea pono ʻole ia i nā mea pono home, nā kaʻa, nā kelepona paʻa lima, nā PC, nā mea lapaʻau, a me nā lako kukui.Me ka ulu mau a paʻa o ka hoʻokele waiwai o koʻu ʻāina, ʻo nā ʻoihana e like me nā mea pono hale, nā kaʻa, nā kelepona paʻa, nā PC, a me nā mea lapaʻau i loaʻa i ka hoʻomohala wikiwiki e pōmaikaʻi ana mai kahi kaiapuni waho maikaʻi.ʻO ka hoʻomohala ʻana o nā ʻoihana i lalo ua hoʻoulu hou i ka koi no nā plastics.I ka makahiki 2010, aia he 2,286 mau ʻoihana i loko o ka ʻoihana hana ʻāpana plastik o Kina, kahi hoʻonui makahiki o 24.54%;loaʻa ka loaʻa kālā i ka 106.125 biliona yuan, kahi hoʻonui makahiki-ma-makahiki o 26.38%.

I loko o ka 12th Five-Year Plan, ʻo nā ʻoihana o lalo o koʻu ʻāina e like me nā kaʻa, nā mea pono hale, nā mea uila uila, a me nā mea lapaʻau e hoʻomau i ka hoʻomohala wikiwiki.E hoʻomau ka hoʻonui ʻana o ka noi no nā ʻāpana plastic i kēia mau ʻoihana, a e hōʻike pū ka noi i kahi ʻano kiʻekiʻe a me ka pololei.Ua manaʻo ʻia ʻo ia i ka manawa o ka 12th Five-Year Plan, ʻo ke kumukūʻai kūʻai aku o ka ʻoihana hana ʻāpana plastik o Kina e hiki i 170 biliona yuan.Wahi a ka noiʻi CIC, ua hoʻonui hou ʻia ka mana o ka ʻenehana ʻenehana o ka ʻoihana hana ʻāpana plastik o Kina, a ua hoʻomau ka nui o nā kikowaena ʻenehana R&D;ua hoʻoponopono mau ʻia ke ʻano o ka ʻoihana, ka hoʻolālā ʻoihana a me ka hoʻolālā huahana, a ua hoʻonui ʻia ka ikaika o ka ʻoihana;ua hoʻomaikaʻi hou ʻia nā pōmaikaʻi holoʻokoʻa o ka ʻoihana a me ka hoʻoikaika ʻana, e hōʻemi mālie ana ka ʻāpana me nā ʻāina i kūkulu ʻia i ka honua, a ua hōʻea kekahi mau mea i ka pae kiʻekiʻe o ka honua, e komo ana i kahi wā koʻikoʻi o ka hoʻomohala hoʻomau mai kahi ʻāina nui i kahi holomua. a me ka ʻāina ikaika.Ke ulu nei ka ʻoihana hana ʻāpana plastik ma Jiangsu, Zhejiang, Shanghai, Guangdong a me nā wahi ʻē aʻe.ʻO ka helu o nā ʻoihana a me ka nui o ka hana a me ke kūʻai aku aia i ke kūlana kiʻekiʻe ma ka ʻāina, a ʻoi aku ka kiʻekiʻe o ka pae o ka ʻoihana.

Me ka plastic ka mea nui, hana ʻia nā huahana plastik a i ʻole nā ​​ʻāpana e ka hana ʻenehana e like me ka injection, extrusion, a me ka hollow molding.
Hana ʻia nā huahana palaki i ka plastic a polymerized e ka polyaddition a i ʻole polycondensation, i ʻike mau ʻia he plastic a resin paha.Hiki ke hoʻololi manuahi ʻia ke ʻano a me ke ʻano.Hoʻokumu ʻia ia me nā resins synthetic a me nā mea hoʻohui e like me nā fillers, plasticizers, stabilizers, lubricants, a me nā puaʻa.
Hoʻokaʻawale ʻia ka Rubber i ka lāʻau kūlohelohe a me ka synthetic rubber.
No ka laau Hevea sinensis ka nui o ka laau palapa maoli.Ke ʻoki ʻia ka epidermis o ka lāʻau lapaʻau, e kahe ka wai keʻokeʻo keʻokeʻo, i kapa ʻia ʻo Latex.Hoʻopili ʻia ka latex, holoi ʻia, hana ʻia a hoʻomaloʻo ʻia no ka loaʻa ʻana o ka lāʻau kūlohelohe.
Hana ʻia ka lāʻau synthetic e ka synthesis artificial, a hiki ke hoʻohui ʻia nā ʻano ʻano like ʻole me ka hoʻohana ʻana i nā mea maka (monomers).

5) He mea maʻalahi ka hana a hiki ke hana nui ʻia, a ʻoi aku ke kumukūʻai
6) Nui ka hoʻohana ʻana, nā hana he nui, maʻalahi ke kala, a me kekahi pale wela kiʻekiʻe
