he aha ka lole hydrophobic

I ka pili ʻana i nā moena, kamaʻāina nā mea a pau iā lākou. He maʻalahi ka loaʻa ʻana o nā moena ma ka mākeke, akā ke manaʻoʻiʻo nei au he nui ka poʻe i nānā ʻole i ka lole o nā moena. ʻO kaʻoiaʻiʻo, he nīnau nui ka lole o nā moena. I kēia lā, e kamaʻilio ka mea hoʻoponopono e pili ana i kekahi o lākou, ma hope o nā mea a pau, ʻaʻole hiki ke hōʻuluʻulu ʻia kahi lole i nā huaʻōlelo liʻiliʻi.

I kēia lā, e hoʻopuka ka mea hoʻoponopono i kahi lole i loaʻa ka hopena wai i lokolole moena.

He aha ka lole hydrophobic?

ʻO ka lole pale wai - ʻoiaʻiʻo, ʻo ia ka pale ʻana i ka wai mai ke komo ʻana mai kekahi ʻaoʻao o ka lole a i kekahi. He ʻano lole lole hou ia, i haku ʻia me ka polymer waiʻole a me nā mea hanu (PTFE film) i hui pū ʻia me ka lole i hui pū ʻia.

No ke aha e hiki ai i ka wai?

I kēia mau lā, ʻaʻole wai wai ka nui o nā lole moena, ʻo kahi liʻiliʻi wale nō o nā ʻili wai e pili ana i ka moena, e komo i loko ma hope o kekahi manawa, e hāʻawi ana i kahi nohona maikaʻi no ka bacteria a me nā mite. A no nā lole wai ʻole, ʻaʻole i ʻike ʻia kēlā ʻano kūlana. ʻO kāna kumu i loko o ka mokuʻāina o ka wai, he liʻiliʻi loa nā ʻāpana wai, a e like me ke kumu o ka neʻe ʻana o ka capillary, hiki iā lākou ke komo mālie i ka capillary i kēlā ʻaoʻao, e hopena i ke ʻano o ka permeability. Ke hoʻokuʻu ʻia ka mahu wai i loko o nā kulu wai, ʻoi aku ka nui o nā ʻāpana. Ma muli o ke kuʻekuʻe ʻana o nā kulu wai (huki a kūʻē nā molekala wai i kekahi i kekahi), ʻaʻole hiki i nā molekala wai ke wehe mālie mai nā kulu wai a komo i kēlā ʻaoʻao, e pale ana i ka hoʻokomo ʻana o ka wai a hana i ka membrane breathable. ʻO kaspunbond lole ʻaʻole i ulana ʻiahana ʻia e Liansheng he hopena wai ʻole a hoʻohana nui ʻia i ka hana ʻana i nā ʻeke puna i nā moena. He kūʻai kūʻai a paʻa.

He aha nā hiʻohiʻona nui o nā lole wai?

ʻO nā hana nui o nā lole ʻaʻahu wai e pili ana i ka wai wai, ka moisture permeability, breathability, insulation, a me ka pale ʻana i ka makani. Ma ke ʻano o ka ʻenehana hana, ʻoi aku ka kiʻekiʻe o nā koi ʻenehana no nā lole wai a me ka hanu ma mua o nā mea no nā lole wai wai maʻamau; I ka manawa like, ma ke ʻano o ka maikaʻi, nā lole wai a me nā mea hanu i loaʻa nā hiʻohiʻona hana i loaʻa ʻole i nā lole wai ʻē aʻe. ʻO nā lole pale wai a me ka hanu ʻaʻole wale e hoʻonui i ka ea a me ka paʻa wai o ka lole, akā loaʻa pū kekahi breathability kūikawā. Hiki iā lākou ke hoʻokuke koke i ka mahu wai i loko o ka hale, pale i ka ulu ʻana o ka pala, a mālama mau i ke kino o ke kanaka. Hoʻoponopono maikaʻi lākou i nā pilikia o ka hanu, ka pale ʻana i ka makani, ka wai ʻole, a me ka mahanahana, e hoʻolilo iā lākou i ʻano hou o ka lole olakino a me ke kaiapuni.

ʻO ka moena he mea pono e moe ai i ko mākou ola i kēlā me kēia lā. Inā he mau keiki ʻoi aku ka ikaika ma ka home, hiki iā ʻoe ke noʻonoʻo e kūʻai i kahi moena i hana ʻia me ka lole wai ʻole e hoʻohana hou ai, hiki ke hoʻemi i ka nui o ka pilikia i kou ola.

Pehea e pale ai i ka wai

1. ʻO ke kumu a Yang

Hāʻule kahi kulu wai ma luna o kahi ʻili paʻa, me ka manaʻo he palahalaha ka ili, ua hoʻopaʻa ʻia ka umekaumaha o ka droplet ma kahi kiko, a ʻaʻole mālama ʻia ka nui o ke kula. Ma muli o ka pilina ma waena o ka ʻili o ka ʻili (Ys) o nā fibers i ka lole, ka ʻili o ka ʻili (YL) o nā wai, a me ka interfacial tension (YLS) o nā mea paʻa, e hana nā droplets i nā ʻano like ʻole (mai ka cylindrical a palahalaha loa). Ke kaulike ka kulu wai ma luna o ka ʻili paʻa, ʻo ka helu A e kau ʻia i ka hopena o ka ʻumekaumaha i hoʻopuehu ʻia, koe wale nō ka pae hoʻopololei piha.

Ua kapaia ka huina 0 ka huina hoopili, Ina 0= I ka hora 00, pulu ka kulu wai i ka ili paa ma ka pale pulupulu, oia ka palena palena o ka ili paa e pulu ana e ke kula. I ka 0=1800, he cylindrical ka kulu wai, kahi kūlana maikaʻi ʻole ka wai. I ka pau ʻana o ka hoʻopau ʻana i ka wai, hiki ke manaʻo ʻia ka ʻili o ka kulu wai ma ke ʻano he mau. No laila, inā hiki i ka māla ke pulu i ka ʻili paʻa e like me ke ʻano o ka relay o ka lau lotus make ma ka ʻili paʻa i ka panakō. Ua ʻōlelo ʻia he ʻoi aku ka maikaʻi o kahi kihi pili nui o 0 no ka wai droplet Rolling loss, ʻo ia hoʻi ka liʻiliʻi ʻoi aku ka maikaʻi.

2. Ka hana adhesion lole

Ma muli o ka hiki ʻole ke ana pololei ʻia ʻo Ys a me YLS, hoʻohana mau ʻia ka huina hoʻopili 0 a i ʻole cos0 e loiloi pololei i ke kiʻekiʻe o ka pulu. Eia naʻe, ʻaʻole ke kumu o ka pulupulu ʻana o ka huina pili, a no laila ʻo ka hopena maoli he ʻāpana e hōʻike ana i ka hana adhesion a me kahi pilina ma waena o lākou, a me ke ʻano o ka pulu.

Hiki ke ana ʻia ʻo YL a me cos0, e hōʻike ana i ka hana adhesive, no laila he koʻikoʻi ko ka hoohalike. Pēlā nō, ʻo 2YL ka hana e pono ai e puʻunaue i kahi kulu wai no kēlā me kēia ʻāpana o ka ʻāpana i ʻelua kulu, hiki ke kapa ʻia ʻo ka hana hui pū o ka wai. Mai ka hoʻohālikelike, hiki ke ʻike ʻia i ka piʻi ʻana o ka hana adhesion, e emi ana ka huina pili. Ke like ka hana adhesion me ka hana cohesive, ʻo ia hoʻi, ʻaʻole ka huina pili. ʻO ia hoʻi, ua palahalaha loa ka wai ma ka ʻili paʻa. No ka mea ʻaʻole hiki ke ʻoi aku ka cos0 ma mua o 1, ʻoiai inā ʻoi aku ka nui o ka hana adhesion ma mua o 2YL, ʻaʻole i loli ka huina pili. Ina WSL = "YL, a laila 0 ka 900. Ina he 180 ° ka huina pili, WSL=O, e hoike ana aole he hopena viscous ma waena o ka wai a me ka paa. Eia naʻe, ma muli o kekahi hopena pipili ma waena o nā ʻāpana ʻelua, ʻaʻole i ʻike ʻia ke kūlana kahi e like ai ka huina pili me 180 °, a ʻo ka hapa nui loa, hiki ke loaʻa i kekahi mau ʻāpana like ʻole, ʻoi aku ka nui.

3. Ko'iko'i ili o ka lole

Ma muli o ke ana ʻaneʻane hiki ʻole ke ana o ka ʻili paʻa paʻa, i mea e hoʻomaopopo ai i ka pulu ʻana o ka ʻili paʻa, ua ana kekahi i kona ʻili koʻikoʻi. ʻOiai ʻaʻole hiki ke hōʻike pololei i ka ʻili o ka ʻili i ka ʻili o ka paʻa, akā ʻo ka nui o Ys YLS, hiki iā ia ke hōʻike i ka paʻakikī o ka pulu ʻana i ka ʻili o ka paʻa. Akā, pono ia

Pono e hoʻomaopopo ʻia ʻo ke ana ʻana i ka haʻalulu koʻikoʻi o ka ʻili he ala empirical a he haiki loa ka laulā o ke ana.

Hiki ke ʻike ʻia, koe wale ka cellulose, ʻauhau ʻia ka haʻahaʻa haʻahaʻa o ka ʻili koʻikoʻi o nā mea a pau, no laila, loaʻa iā lākou a pau ke ʻano o ka pale wai, ʻo CF3 ka mea nui a ʻo CH ka mea liʻiliʻi loa. ʻIke loa, ʻo kēlā me kēia noho waiwai me ka hāʻawi ʻana aku i ka hoʻopili nui a me ka haʻalulu koʻikoʻi liʻiliʻi liʻiliʻi, a me nā mea hoʻopau hoʻopau, hiki ke loaʻa i nā hopena repellent wai.
