He aha ka polyvinyl alcohol (PVA)?

Ua palekana anei ka waiʻona polyvinyl?

Hoʻopili pinepine ʻia ʻo PVA me ka polyvinyl acetate (PVAc), kahi kelu lāʻau, a me ka polyvinyl chloride (PVC), kahi mea i loaʻa nā phthalates a me nā metala kaumaha. ʻO nā mea ʻekolu he polymers, akā he mau mea ʻokoʻa loa lākou.

ʻO ka waiʻona Polyvinyl he polimer non-toxic, biodegradable, a me nā huahana i loaʻa i ka PVA palekana ke hoʻohana a palekana hoʻi e ʻai. Ua koho ka Environment Working Group iā ia ma ke ʻano he haʻahaʻa haʻahaʻa haʻahaʻa i nā mea hoʻonaninani, a ua ʻae ka Food and Drug Administration i ka PVA no ka hoʻohana ʻana i nā meaʻai a me nā noi lāʻau.

Hoʻoheheʻe ʻia ka waiʻona polyvinyl i ka wai?

ʻAe, hiki i ka PVA ke hoʻoheheʻe koke, ʻoiai i ka wai anuanu. Ma hope o ka hoʻoheheʻe ʻia ʻana o ke kiʻiʻoniʻoni PVA, hiki i kekahi o nā ʻano microorganism 55 i loaʻa i loko o nā ʻōnaehana hoʻomaʻemaʻe wai ʻino ke wāwahi i ke koena o ke kiʻiʻoniʻoni i hoʻoheheʻe ʻia.

Ke hopohopo nei kekahi poʻe no ka loaʻa ʻana o kēia mau microorganisms i ka nui o ka nui o ka hoʻokaʻawale ʻana i ke kiʻiʻoniʻoni PVA. ʻO ka nūhou maikaʻi, ʻo ka hapa nui o nā ʻōnaehana wai ʻino ka nui o kēia mau microbes, no laila ua manaʻo ʻia ʻo PVA he mea hiki ke hoʻoheheʻe ʻia.

ʻO PVA kahi kumu o nā microplastics?

ʻAʻole kōkua ke kiʻi ʻoniʻoni PVA i ka hoʻohaumia ʻana i ka microplastic a i ʻole ka hoʻokō ʻana i kekahi o nā wehewehe ʻana o kahi microplastic: ʻaʻole ia he micro- a i ʻole ka nui nano, hiki ke hoʻoheheʻe ʻia i ka wai, a he biodegradable. Ua hōʻike ʻia kahi haʻawina mai ka American Cleaning Institute ma kahi o 60% o nā biodegrades kiʻiʻoniʻoni PVA i loko o 28 mau lā, a ma kahi o 100% i biodegraded i loko o 90 mau lā a i ʻole.

He ino anei ka waiona polyvinyl no ke kaiapuni?

Hoʻolālā ʻia ka waiʻona Polyvinyl e hiki ke hoʻoheheʻe ʻia, ʻaʻole ia e hoʻokahe a wāwahi ʻole i loko o nā microplastics i kēlā me kēia manawa. Ke hoʻoheheʻe ʻia ka kiʻiʻoniʻoni PVA a holoi ʻia i lalo o ke kahawai, hoʻoheheʻe ʻia ia e nā mea ola i loko o ka wai ʻino - a ʻo ia ka hopena o ke ola ola PVA.

No ke aha wau e lohe nei i nā mea hoʻolako he nui no PVA i kēia manawa?

Ua kauoha kekahi mau mea kūʻai aku i nā noiʻi kūʻokoʻa e pili ana i ka waiʻona polyvinyl, e hana ana i kahi huikau e pili ana i nā huahana JINJI a me nā mea kūʻai aku ʻē aʻe. A maikaʻi kēlā! Makemake mākou i nā mea kūʻai aku ʻo JINJI - a me nā mea kūʻai aku ma ke ʻano nui - e ʻimi e pili ana i nā mea i loko o nā huahana a lākou e hoʻohana ai. Akā he mea nui e nānā i nā haʻawina kūʻokoʻa ma mua o kou hoʻokumu ʻana i kou manaʻo a hoʻololi i kāu mau kūʻai kūʻai. E hoʻopaʻa iā ʻoe iho me ka ʻike mai nā kumu kaulana a me ka ʻole e kōkua iā ʻoe e pale aku i ka hoʻopunipuni ʻia e ka holoi ʻōmaʻomaʻo - a i ʻole e hoʻonāwaliwali ʻia e ka makaʻu.

ʻO ka waiʻona polyvinyl a me ke kaiapuni

Aia nā huahana JINJI i ka PVA?

ʻO PVA, i kapa ʻia ʻo PVOH a i ʻole PVAI, he polymer synthetic ʻaʻole waihoʻoluʻu a ʻala ʻole. He aha ka mea kūikawā o ka waiʻona polyvinyl he hiki ke hoʻoheheʻe ʻia i ka wai, he ala maikaʻi ia e ʻōlelo ai e hoʻoheheʻe ʻia i ka wai. Ma muli o kona hiki ke hoʻoheheʻe ʻia i ka wai, hoʻohana pinepine ʻia ʻo PVA ma ke ʻano he uhi kiʻiʻoniʻoni ma ka holoi lole a me ka ipu holoi kīʻaha, akā loaʻa pū kekahi i nā huahana e like me nā mea hoʻonaninani, shampoos, kulu maka, ʻeke meaʻai hiki ke ʻai, a me nā capsules lāʻau.

Hoʻohana ʻo JINJI RDP i nā mea PVA i hiki ke hoʻoheheʻe ʻia i ka wai. I ka manawa o ka PVA a me ka VAE pane, e maloʻo a hana i ka pauka RDP.

Aia ʻo JINJI i kahi misionari e hana i nā mea ʻokoʻa eco-friendly no ka home a me nā huahana mālama pilikino a me nā mea hoʻonaninani. Makemake mākou e hana i nā mea pono home hoʻomau e kākoʻo i nā hoʻonā kaiapuni ma mua o ka luku ʻana i ke kaiapuni. Ke hoʻopau nei mākou i ka ʻeke plastik mai kā mākou huahana a hana i kā mākou ʻāpana e hana i kahi wā e hiki mai ana.
