ʻeke ʻeke o loko o ka ʻeke kī Hoʻopili

ʻOiai ʻo ia kekahi o nā mea inu waiʻona nui ʻekolu o ka honua, makemake nui ʻia ke kī e ka poʻe no kāna mau ʻano kūlohelohe, meaʻai, a me ke olakino. I mea e mālama pono ai i ke ʻano, ka waihoʻoluʻu, ka ʻala, a me ka ʻono o ke kī, a hoʻokō i ka mālama ʻana a me ka lawe ʻana i ka wā lōʻihi, ua loaʻa pū ka ʻeke kī i nā hoʻololi a me nā mea hou. Mai kona hoʻomaka ʻana, ua kaulana ke kī ʻeke ma nā ʻāina ʻEulopa a me ʻAmelika ma muli o kāna mau pono he nui e like me ka maʻalahi a me ka maʻemaʻe.

ʻO ke kī ʻeke he ʻano kī i hoʻopaʻa ʻia i loko o nā ʻeke pepa kānana lahilahi a hoʻokomo pū ʻia me ka ʻeke pepa i loko o ka ʻeke kī. ʻO ke kumu nui o ka hoʻopili ʻana me nā ʻeke pepa kānana ʻo ia ka hoʻomaikaʻi ʻana i ka nui o ka leaching a me ka hoʻohana pono ʻana i ka pauka kī i loko o ka hale hana kī. Ma muli o kāna mau mea maikaʻi e like me ka wikiwiki ʻana, ka hoʻomaʻemaʻe, ke ʻano maʻamau, ka hui ʻana maʻalahi, ka wehe ʻana i ke koena kūpono, a me ka lawe ʻana, makemake nui ʻia ke kī ʻeke ma ka mākeke honua e hoʻokō i nā pono o ka nohona wikiwiki o ka poʻe hou. ʻO nā mea kī kī, nā mea hoʻopihapiha, a me nā mīkini ʻeke kīʻaha kīʻaha ʻekolu mau mea o ka hana ʻeke kī, a ʻo nā mea hoʻopili ke kumu kumu no ka hana ʻana i ka ʻeke kī.

Nā ʻano a me nā koi o nā mea hoʻopili no nā ʻeke kī

ʻO nā mea hoʻopili no nā ʻeke kī he mau mea hoʻopili i loko e like mepepa kānana kī, nā mea hoʻopili waho e like me nā ʻeke o waho, nā pahu pahu, a me ka plastic transparent a me ka pepa aniani, ʻo ia ka pepa kānana kī ka mea nui loa. Eia kekahi, i ka wā o ke kaʻina hana piha piha o nā ʻeke kī, ʻeke kīkaula pulupuluno ka hoʻokiʻekiʻe ʻana o ka milo, ka pepa lepili, ka hāpai ʻana i ke kaula adhesive, a me ka acetate polyester adhesive no nā lepili. Loaʻa i ke kī nā mea e like me ascorbic acid, tannic acid, polyphenolic compounds, catechins, fats, a me carotenoids. He mea maʻalahi kēia mau mea i ka pōʻino ma muli o ka makū, ka oxygen, ka mahana, ka māmā, a me nā mea ʻala. No laila, ʻo nā mea hoʻopihapiha i hoʻohana ʻia no nā ʻeke kī e hoʻokō maʻamau i nā koi o ka pale ʻana i ka wai, ka pale ʻana o ka oxygen, ke kūpaʻa wela kiʻekiʻe, ka pale māmā, a me ka pale ʻana i ke kinoea e hōʻemi a pale i ka hopena o nā mea i luna.

1. Mea hoʻopili i loko no nā ʻeke kī - pepa kānana kī

ʻO ka pepa kānana ʻeke kī, ʻike ʻia hoʻi ʻo ka pepa ʻeke kī ʻeke pepa, he pepa lahilahi haʻahaʻa me kahi ʻano like ʻole, maʻemaʻe, ʻoluʻolu a porous, haʻahaʻa paʻa, ikaika absorption, a me ka ikaika pulu kiʻekiʻe. Hoʻohana nui ʻia ia no ka hana ʻana a me ka hoʻopili ʻana i nā "ʻeke kī" i nā mīkini pahu kī kī. Ua kapa ʻia ʻo ia ma muli o kona kumu, a ʻo kāna hana a me ka maikaʻi e pāʻani nui i ka maikaʻi o nā ʻeke kī i hoʻopau ʻia.

1.2 Nā koi kumu no ka pepa kānana kī

Ma ke ʻano he mea hoʻopili no nā ʻeke kī, ʻaʻole pono e hōʻoia ka pepa kānana kī i hiki ke hoʻopuehu koke nā mea pono o ke kī i loko o ka sopa kī i ka wā o ke kaʻina hana brewing, akā e pale pū i ka pauka kī i loko o ka ʻeke mai ke komo ʻana i loko o ka sopa kī. ʻO nā koi kiko'ī no kona mauʻano penei.
(l) Loaʻa ka ikaika mechanical (kiʻekiʻe tensile ikaika) e hoʻololi i ka ikaika maloʻo a me ka elasticity o nā mīkini hoʻopihapiha piha no nā ʻeke kī;
(2) Hiki iā ia ke kū i ka hoʻolulu ʻia i loko o ka wai paila me ka haki ʻole;
(3) He ʻano porous, pulu, a permeable ke kī ʻeke. Ma hope o ka hoʻoinu ʻana, hiki ke hoʻomaʻemaʻe koke ʻia a hiki ke hoʻoheheʻe koke ʻia nā mea hoʻoheheʻe ʻia o ke kī;
(4) Pono e maikaʻi, ʻaʻahu like a paʻa nā fiber.
ʻO ka mānoanoa o ka pepa kānana he 0.003-0.009in (lin=0.0254m)
Pono ka nui o ka pore o ka pepa kānana ma waena o 20-200 μm, a pono e kaulike ka nui a me ka porosity o ka pepa kānana.
(5) Odorless, odorless, non-toxic, e like me nā koi o ka maʻemaʻe;
(6) Māmā, me ka pepa keʻokeʻo.

1.3 ʻAno Pepa kānana kī

Hoʻokaʻawale ʻia nā mea hoʻopihapiha no nā ʻeke kī i ka honua i kēia lā i ʻelua ʻano:pepa kānana kī i hoʻopaʻa ʻia me ka welaa me ka pepa kānana kī i hoʻopaʻa ʻole ʻia me ka wela, e hilinaʻi ana inā pono lākou e wela a hoʻopaʻa ʻia i ka wā e hoʻopaʻa ai i ka ʻeke. ʻO ka pepa kānana kī i hoʻopaʻa ʻia i ka wela.

ʻO ka pepa kānana kī i hoʻopaʻa ʻia me ka wela he ʻano pepa kānana kī kūpono no ka hoʻopaʻa ʻana i nā mīkini hoʻopaʻa ʻana i ka wela. Pono ia e haku ʻia me 30% -50% lōʻihi a me 25% -60% wela i hoʻopaʻa ʻia. ʻO ka hana o nā fiber lōʻihi ka hāʻawi ʻana i ka ikaika mechanical i ka pepa kānana. Hoʻohui ʻia nā fiber i hoʻopaʻa ʻia me ka wela i ka wā o ka hana ʻana i ka pepa kānana, e ʻae ana i nā ʻāpana ʻelua o ka pepa kānana e hoʻopaʻa pū i ka wā i hoʻomehana ʻia a kaomi ʻia e nā wili hoʻopaʻa wela o ka mīkini pahu, no laila e hana ai i kahi ʻeke wela. Hiki ke hana ʻia kēia ʻano fiber me nā waiwai hoʻopaʻa wela mai nā copolymers o ka polyvinyl acetate a me ka polyvinyl chloride, a i ʻole mai ka polypropylene, polyethylene, synthetic silk, a me kā lākou hui ʻana. Hana kekahi mau mea hana i kēia ʻano pepa kānana i ʻano papalua-papa, me ka papa hoʻokahi i hoʻopaʻa piha ʻia me nā fiber hui pū ʻia i hoʻopaʻa ʻia me ka wela a ʻo kekahi papa ʻē aʻe me nā fibers i hoʻopaʻa ʻole ʻia. ʻO ka pōmaikaʻi o kēia ʻano hana, ʻo ia ka mea hiki ke pale i nā fibers i hoʻopaʻa ʻia i ka wela mai ka hoʻopili ʻana i nā wili sealing o ka mīkini ma hope o ka hoʻoheheʻe ʻia e ka wela. Hoʻoholo ʻia ka mānoanoa pepa e like me ke kūlana o 17g/m2.

ʻO ka pepa kānana ʻaʻole wela he pepa kānana kī kūpono no ka hoʻopili ʻana i nā mīkini kīʻaha kīʻaha ʻole wela. Pono ka pepa kānana kī ʻole i hoʻopaʻa ʻia me ka wela he 30% -50% ka lōʻihi, e like me Manila hemp, no ka hoʻolako ʻana i ka ikaika mechanical, ʻoiai ʻo ke koena i haku ʻia me nā fibers pōkole a me 5% resin. ʻO ka hana o ka resin ka hoʻomaikaʻi ʻana i ka hiki o ka pepa kānana ke kū i ka wai paila. Hoʻoholo ʻia kona mānoanoa ma muli o ke kaumaha maʻamau o 12 grams no ka mika square. Ua hoʻohana ka poʻe noiʻi mai ke Keʻena ʻEpekema Forest Resources ma Shizuoka Agricultural University ma Iapana i hana ʻia e Kina i ka hemp bast fiber i hoʻomoʻa ʻia i ka wai ma ke ʻano he kumu waiwai, a ua aʻo i nā waiwai o ka hemp bast fiber pulp i hana ʻia e ʻekolu mau ʻano kuke: alkaline alkali (AQ) pulping, ʻO ka pulping sulfate, a me ka pulping alkaline lewa. Manaʻo ia e hiki i ka pulping alkaline o ka hemp bast fiber ke hoʻololi i ka pulp hemp Manila i ka hana ʻana i ka pepa kānana kī.

Eia kekahi, ʻelua ʻano pepa kānana kī: bleached a me unbleached. I ka wā ma mua, hoʻohana ʻia ka ʻenehana bleaching chloride, akā i kēia manawa, hoʻohana nui ʻia ka bleaching oxygen a i ʻole ka pulp bleached e hana i ka pepa kānana kī.

Ma Kina, hana pinepine ʻia nā ʻili mulberry e ka pulping mokuʻāina manuahi a laila hana ʻia me ka resin. I kēia mau makahiki i hala iho nei, ua ʻimi nā kānaka noiʻi Kina i nā ʻano pulping like ʻole e pili ana i ka ʻoki ʻana, ka pehu, a me nā hopena fiber maikaʻi o nā fiber i ka wā o ka pulping, a ʻike ʻia ʻo ke ʻano pulping maikaʻi loa no ka hana ʻana i ka pulp pepa ʻeke kī ʻo "long fiber free pulping". Ke hilinaʻi nui nei kēia ʻano kuʻi i ka ʻoki ʻana, ʻoki kūpono, a me ka hoʻāʻo ʻana e mālama i ka lōʻihi o nā ʻili me ka ʻole e koi ʻia i nā fiber maikaʻi loa. ʻO nā hiʻohiʻona o ka pepa he absorption maikaʻi a me ka hanu kiʻekiʻe. Ma muli o ka lōʻihi o nā fibers, ʻilihune ka like ʻole o ka pepa, ʻaʻole maʻalahi ka ʻili o ka pepa, kiʻekiʻe ka opacity, maikaʻi ka waimaka ikaika a me ka lōʻihi, maikaʻi ka paʻa o ka pepa, a ʻo ka deformation. liʻiliʻi.
