ʻO ka resin ke kumu nui o kahi hui organik i paʻa, semi-solid a pseudo-solid paha i ka mahana o ka lumi, a ma ke ʻano laulā he palupalu a he heheʻe paha ma hope o ka hoʻomehana ʻia ʻana. Ke palupalu ʻia, hoʻopilikia ʻia e nā mana o waho a he ʻano maʻamau ke kahe. Ma ke ʻano ākea, ma hea e hiki ai i nā polymers ma ke ʻano he matrix plastic ke lilo i resins.

ʻO ka palakiko e pili ana i kahi mea polymer organik i hana ʻia e ka hoʻoheheʻe ʻana a me ka hana ʻana me ka resin ma ke ʻano he mea nui, e hoʻohui ana i kekahi mau mea hoʻohui a i ʻole nā ​​​​mea kōkua.

Nā ʻano plastik maʻamau:

Nā palakiko maʻamau: polyethylene, polyvinyl chloride, polystyrene, polymethylmethacrylate.

ʻO nā palakiko ʻenekinia maʻamau: polyester amine, polycarbonate, polyoxymethylene, polyethylene terephthalate, polybutylene terephthalate, polyphenylene ether a i ʻole ka polyphenylene ether i hoʻololi ʻia, a pēlā aku.

Nā palakiko ʻenekinia kūikawā: polytetrafluoroethylene, polyphenylene sulfide, polyimide, polysulfone, polyketone a me ka polymer kristal wai.

Nā palakiko hana: nā palakiko alakaʻi, nā palakiko piezoelectric, nā palakiko magnetic, nā olonā optical palakiko a me nā palakiko optical, a pēlā aku.

ʻO nā plastics thermosetting maʻamau: resin phenolic, resin epoxy, polyester unsaturated, polyurethane, silicone a me ka plastic amino, a pēlā aku.

Nā puna palaki, kekahi o kā mākou huahana plastik nui, ua hana ʻia mai nā mea maka PP papa meaʻai. Me kanā ʻauwaha palaki, nā lāʻau hanu ihu, ʻo nā lako lapaʻau a i ʻole nā ​​​​lako hana hoʻokolohua a i ʻole nā ​​​​lako kīhini o ka hale he mau mea maka no ka meaʻai.

Nā wahi noi plastik:

1. Nā mea hoʻopili. ʻO nā mea hoʻopili ka hoʻohana nui ʻana o nā plastik, ʻoi aku ma mua o 20% o ka huina. Ua māhele ʻia nā huahana nui i:

(1) Nā huahana kiʻiʻoniʻoni, e like me ke kiʻiʻoniʻoni wahī māmā a kaumaha, ke kiʻiʻoniʻoni pale, ke kiʻiʻoniʻoni hoʻēmi wela, ke kiʻiʻoniʻoni hoʻopili ponoʻī, ke kiʻiʻoniʻoni anti-rust, ke kiʻiʻoniʻoni haehae, ke kiʻiʻoniʻoni cushion ea, a pēlā aku.

(2) Nā huahana ʻōmole, e like me nā ʻōmole ʻōpala meaʻai (ʻaila, pia, soda, waina keʻokeʻo, vīnega, soy sauce, a pēlā aku), nā ʻōmole hoʻonani, nā ʻōmole lāʻau lapaʻau a me nā ʻōmole reagent kemika.

(3) Nā huahana pahu, e like me nā pahu meaʻai, nā lako, nā hana lima, nā lako moʻomeheu a me ka hoʻonaʻauao, a pēlā aku.

(4) Nā huahana kīʻaha, e like me nā kīʻaha mea inu hoʻolei, nā kīʻaha waiū, nā kīʻaha yogurt, a pēlā aku.

(5) Nā huahana pahu, e like me nā pahu pia, nā pahu soda, nā pahu meaʻai

(6) Nā huahana ʻeke, e like me nā ʻeke lima a me nā ʻeke ulana

2. Nā mea pono o kēlā me kēia lā

(1) Nā huahana like ʻole, e like me nā kīʻaha, nā barela, nā pahu, nā hīnaʻi, nā pā, nā noho, a pēlā aku.

(2) Nā mea moʻomeheu a me nā mea haʻuki, e like me nā peni, nā lula, badminton, tennis papaʻaina, a pēlā aku.

(3) Nā lole meaʻai, e like me ke kapuaʻi kāmaʻa, ka ʻili hana, ka ʻili hana, nā pihi, nā pine lauoho, a pēlā aku.

(4) Nā lako kīhini, e like me nā puna, nā papa ʻokiʻoki, nā ʻō, a pēlā aku.

ʻO ia wale nō no kēia lā, a hui hou kākou.
