ʻO nā pono o nā Plastics

He paʻa maʻamau nā plastik.Hiki iā lākou ke amorphous, crystalline, a i ʻole semi crystalline solids (crystallites).
ʻO nā plastik ka mea maʻamau i ka wela a me ka uila.ʻO ka hapa nui he insulators ikaika dielectrically.
ʻOoleʻa maʻamau nā polymers aniani (e laʻa, polystyrene).Hiki ke hoʻohana ʻia nā ʻāpana lahilahi o kēia mau polymers ma ke ʻano he kiʻiʻoniʻoni (e laʻa, polyethylene).
Ke koʻikoʻi, kokoke i nā plastics āpau e hōʻike i ka elongation ʻaʻole e ola hou ma hope o ka hemo ʻana o ke kaumaha.Ua kapa ʻia kēia ʻo "creep."
He lōʻihi a hoʻohaʻahaʻa ʻia nā plastik ma kahi wikiwiki.

Nā hoʻohana ʻana i nā Plastics

Ma na Homes

He nui ka nui o ka plastik ma ke kīwī, ka ʻōnaehana kani, ke kelepona hele, ka mea hoʻomaʻemaʻe hoʻomaʻemaʻe, a ʻo ka mea nui paha i loko o ka huʻa plastik i loko o nā lako.Noho ʻili a i ʻole nā ​​noho bar, nā papa kuʻekuʻe acrylic, nā linings PTFE i loko o nā pā kuke nonstick, a me nā paipu plastik i loko o ka ʻōnaehana wai.

Kaʻa a me ka lawe ʻana

Ua hāʻawi nā plastics i nā mea hou i ka hoʻolālā automotive, me ka hoʻomaikaʻi ʻana i ka palekana, ka hana, a me ka pono wahie.

Hoʻohana nui ʻia nā plastik i nā kaʻaahi, nā mokulele, nā kaʻa, a me nā moku, nā satelite, a me nā kikowaena lewa.He mau hiʻohiʻona wale nō nā bumpers, dashboards, engine parts, noho, a me nā puka.

Hana Hana

Hoʻohana ʻia nā plastik i nā ʻano he nui i ke kahua kūkulu.Loaʻa iā lākou kahi kiʻekiʻe o ka versatility a hoʻohui i ka ratio ikaika-a-kaumaha maikaʻi, ka lōʻihi, ke kumukūʻai-pono, ka mālama haʻahaʻa, a me ka pale ʻana i ka corrosion, e hana ana i nā plastics i koho hoʻokele waiwai i ka ʻoihana kūkulu.

• Conduit and Piping
• Hoʻopili a me nā kiʻi - Hoʻopili a me nā kiʻi no nā puka makani, nā puka, ka coving a me ke kapa.
• ʻO nā pahu a me nā sila
• ʻO ka hoʻokaʻawale

Hoʻopili ʻia

Hoʻohana ʻia nā ʻano plastics e pūʻolo, hoʻopuka, mālama, a lawelawe i nā meaʻai a me nā mea inu.Koho ʻia nā plastik i hoʻohana ʻia i ka ʻeke meaʻai no kā lākou hana: ʻaʻole inert a kūʻē i nā kemika i ke kaiapuni waho a me nā meaʻai a me nā mea inu ponoʻī.

• Hoʻolālā kūikawā ʻia ka nui o nā ipu plastik a me nā ʻōwili i kēia lā no ke kū ʻana i nā mahana wela microwave.
• Loaʻa ka pōmaikaʻi hou o ka nui o nā ipu meaʻai plastik no ka hiki ke hoʻololi palekana mai ka pahu hau a i ka microwave i ka holoi kīʻaha.

Nā Mea Hana Palekana Haʻuki

• ʻOi aku ka māmā a ʻoi aku ka ikaika o nā lako palekana haʻuki, e like me nā mahiole plastik, nā kiaʻi waha, nā maka aniani, a me nā pale pale, e mālama i nā mea āpau.
• Hoʻopaʻa paʻa a kākoʻo ʻia nā wāwae i hoʻoheheʻe ʻia me ka haʻalulu, a ʻo nā pūpū plastik paʻakikī e uhi ana i nā mahiole a me nā pale pale e pale i nā poʻo, nā hono a me nā iwi.

Kahua lapaʻau

Ua hoʻohana nui ʻia nā plastics i ka hana ʻana i nā mea lapaʻau a me nā mea hana e like me nā mīkina lima ʻokiʻoki, nā syringes, nā peni insulin, nā paipu IV, nā catheters, nā splints inflatable, nā ʻeke koko, nā paipu, nā mīkini dialysis, nā puʻuwai puʻuwai, nā lālā artificial, a me nā ʻaʻahu ʻeha. nā mea ʻē aʻe.

ʻO nā pono o ka Plastic

• Nā ʻike e pili ana i nā Plastics
• ʻO Bakelite, ka plastic synthetic mua loa, i hana ʻia i ka makahiki 1907 e Leo Baekeland.Eia kekahi, ua hoʻokumu ʻo ia i ka huaʻōlelo "plastic."
• Ua loaʻa ka huaʻōlelo "plastic" mai ka huaʻōlelo Helene plastikos, ʻo ia hoʻi "hiki ke hana ʻia a hoʻoheheʻe ʻia."
• Hoʻopili ʻo Packaging i kahi hapakolu o nā ʻilika i hana ʻia.Hoʻolaʻa ʻia kahi hapakolu o ka wahi no ka ʻaoʻao a me ka paipu.
• Ma keʻano laulā, ʻaʻole hiki ke hoʻoheheʻe ʻia nā plastik maʻemaʻe i ka wai a ʻaʻole ʻona.ʻO ka nui o nā mea hoʻohui i loko o nā plastics, he mea ʻawaʻawa a hiki ke lele i loko o ke kaiapuni.ʻO Phthalates kahi laʻana o kahi mea hoʻohui ʻona.Ke hoʻomehana ʻia nā polymers nontoxic, hiki ke hoʻohaʻahaʻa i nā kemika.
• Nā nīnau i nīnau pinepine ʻia e pili ana i ka hoʻohana ʻana i nā plastik
• He aha nā pōmaikaʻi a me nā hemahema o ka plastic?
• ʻO nā pono a me nā hemahema o ka plastic penei:

Nā pōmaikaʻi:

ʻOi aku ka maʻalahi a ʻoi aku ke kumukūʻai ma mua o nā metala.
He lōʻihi loa nā plastic a hiki ke hoʻomau no ka manawa lōʻihi.
ʻOi aku ka wikiwiki o ka hana ʻana i ka plastik ma mua o ka hana metala.

Nā hemahema:

• He 400 a 1000 mau makahiki ka ho'ohehe'e maoli 'ia o ka plastic, a he mau 'ano plastics wale no ka biodegradable.
• Hoʻohaumia nā mea palaki i nā kino wai e like me ke kai, ke kai, a me nā loko, e pepehi ana i nā holoholona kai.
• I kēlā me kēia lā, nui nā holoholona e ʻai i nā huahana plastik a make i ka hopena.
• ʻO ka hana ʻana a me ka hana hou ʻana e hoʻopuka i nā kinoea ʻino a me nā koena e hoʻohaumia ai i ka ea, ka wai, a me ka lepo.
• Ma hea kahi i hoʻohana nui ʻia?
• I kēlā me kēia makahiki, ʻoi aku ma mua o 70 miliona tons o nā thermoplastics i hoʻohana ʻia i nā textiles, ka mea nui i ka lole a me ke kapena.

He aha ke kuleana o ka plastic i ka hoʻokele waiwai?

He nui nā pono hoʻokele waiwai a hiki ke kōkua i ka pono waiwai.Hoʻemi ia i ka pau ʻana o ka meaʻai ma ka hoʻolōʻihi ʻana i ke ola o ka meaʻai, a ʻo kona māmā e hoʻemi i ka hoʻohana ʻana i ka wahie i ka wā e lawe ai i nā waiwai.

No ke aha mākou e haʻalele ai i ka plastic?

Pono e pale ʻia nā plastik no ka mea hiki ʻole ke biodegradable.Lawe lākou i mau makahiki e decompose ma hope o ka hoʻokomo ʻia ʻana i ke kaiapuni.Hoʻohaumia nā plastik i ke kaiapuni.
