Nā Polokalamu Koʻikoʻi
He mea koʻikoʻi ʻo Bisphenol A i ka hana ʻana i nā polymers hana kiʻekiʻe a me nā mea ʻoihana, me nā kahua noi koʻikoʻi penei:
Hana ʻana i ka Palakiko Polycarbonate (PC)
Ma ke ʻano he mea maka mua no ka palaki PC, hiki i ka BPA ke hana i nā huahana pale i ka haki a me ka wela e like me nā hale uila (laptops, smartphones), nā ʻāpana kaʻa (nā uhi kukui, nā panela o loko), a me nā ipu meaʻai (i hoʻoponopono ʻia no ka palekana ma ka hapa nui o nā wahi).
Hana ʻana o ka Epoxy Resin
Hoʻohana ʻia e hana i nā resins epoxy no nā uhi (e laʻa me nā uhi o loko o ka pahu, nā uhi anti-corrosion ʻoihana), nā mea hoʻopili (nā mea hoʻopili kūkulu ikaika kiʻekiʻe no ka aerospace a me ke kūkulu ʻana), a me nā mea hoʻokaʻawale uila (nā papa kaapuni, nā wili transformer).
Nā hoʻohana ʻoihana ʻē aʻe
Mea maka no nā polyols polyether (hoʻohana ʻia i nā hua polyurethane).
Hoʻohui i loko o nā plasticizers, nā mea pale ahi, a me nā mea hoʻopaʻa UV no nā mea polymer.
Waena i ka hana ʻana o nā kemika kūikawā (e laʻa, nā antioxidants, nā dyestuffs).
Nā Kūlana Kūlana
Ua kūlike kā mākou huahana Bisphenol A me nā kūlana ʻoihana a me ka palekana honua, me nā ʻōkuhi maʻamau o ka kaohi ʻana i ka maʻemaʻe a me ka haumia e like me kēia:
| Papa Kuhikuhi | Papa ʻOihana (Maʻamau) | Papa Reagent (Maʻemaʻe Kiʻekiʻe) |
|---|---|---|
| Maʻemaʻe (HPLC) | ≥ 99.5% | ≥ 99.8% |
| Ka nui o ka makū | ≤ 0.1% | ≤ 0.05% |
| Ka nui o ka lehu | ≤ 0.01% | ≤ 0.005% |
| Nā mea haumia metala kaumaha (Pb, Cd, Hg) | ≤ 10 ppm | ≤ 1 ppm |
| Koena Phenol | ≤ 0.2% | ≤ 0.05% |
Loaʻa nā kikoʻī i hoʻopilikino ʻia no nā pono ʻoihana kikoʻī (e laʻa, nā pae haumia haʻahaʻa no ka hana ʻana i nā mea pili i ka meaʻai).
Nā Kuhikuhi no ka Mālama ʻana a me ka Lawelawe ʻana
No ka hōʻoia ʻana i ke kūpaʻa o ka huahana a me ka palekana o ka hana, e hahai i kēia mau koi mālama a me ka lawelawe ʻana:
Nā Kūlana Mālama
Mahana: E mālama i kahi maloʻo a anuanu ma 15–25 °C; e pale i ka wela nui (>30 °C) a i ʻole ka hau ʻana (
Mālamalama: E hoʻohana i nā ipu opaque (e laʻa, nā ʻōmole aniani ʻeleʻele, nā pahu plastik HDPE me ka pale UV) e pale aku i ka hōʻino ʻia e ka UV.
Ka Haumākū: E mālama i ka haumākū pili
Nā Pono Sila
E hoʻopaʻa pono i nā ipu ma hope o kēlā me kēia hoʻohana ʻana e pale aku i ka omo ʻana o ka wai a me ka haumia. E pale i ka hoʻohana ʻana i nā ʻano sila manawa pōkole (e laʻa me ka ʻōwili plastik) e hiki ai ke hoʻohaumia keʻa.
Nā Mālama Palekana
E komo i nā lako palekana pilikino (PPE): Pale lepo, nā mīkina lima pale kemika, a me nā maka aniani palekana i ka wā e lawelawe ai (ʻoi aku hoʻi no nā ʻano pauka/granular).
Ea: E hōʻoia i ka ea maikaʻi ma nā wahi mālama a me nā wahi lawelawe e pale aku i ka hōʻiliʻili ʻana o ka lepo a i ʻole ka mahu.
Ka lawelawe ʻana i nā mea i ninini ʻia: E hoʻomaʻemaʻe i nā mea i ninini ʻia me nā mea hoʻomomona inert (lepo diatomaceous, kalapona i hoʻāla ʻia); e hoʻolei i nā ʻōpala e like me nā lula kemika weliweli kūloko.
Hoʻokō kānāwai
Nā Palena Honua: Hoʻokō i nā kapu o ka EU REACH Regulation (Annex XVII) ma ka BPA i nā mea pili i ka meaʻai (e laʻa, ua pāpā ʻia i loko o nā ʻōmole hānai pēpē).
US FDA: Hoʻokō i nā kulekele FDA no ka hoʻohana ʻana i ka BPA i nā uhi pili meaʻai a me nā plastics (21 CFR 175.300).
Nā Kūlana Kina: Kūlike me GB 4806.6 (nā kūlana palekana no nā resins plastik pili meaʻai).
Ka Hoʻopili ʻana a me ke Ola o ka Papa
Nā Koho Hoʻopili:
Papa ʻOihana: 25 kg mau ʻeke palaki HDPE (me nā liner polyethylene o loko) a i ʻole 500 kg mau pahu fiber (i uhi ʻia me ka pepa alumini).
Papa Reagent: 1 kg ʻōmole aniani ʻamber (i sila ʻia me nā pāpale i uhi ʻia me Teflon).
Ola Pale: 24 mau mahina mai ka lā hana (ke mālama ʻia e like me nā kūlana i luna, ʻaʻole i wehe ʻia).
