Wahi a nā helu helu, e loaʻa iā Kina he 302 miliona mau kaʻa i ka lā Dekemaba 2021. Ua hāʻawi mālie ka mākeke mea kūʻai aku i ka koi koʻikoʻi i nā lole kaʻa ʻike ʻole ʻia e like me ka hoʻonui ʻana o ka nui o nā kaʻa a ke piʻi mau nei ke koi no ka mālama ʻana i ka pena.I ke alo o ka hoʻonui ʻana o ka mākeke mea kūʻai aku, e wela ana ka hoʻokūkū ma waena o nā ʻoihana lole kaʻa ʻike ʻole.ʻO ka manaʻo o kēia manawa ʻo ka hoʻokūkū haʻahaʻa haʻahaʻa e pili ana i ke kumu kūʻai, ʻoiai ʻo ka hoʻokūkū kiʻekiʻe e kau ʻia ma nā paepae ʻenehana.
ʻO ka mea huna o ke kiʻi pale hydrophobic layer (1)
Ma muli o ka homogeneous o nā huahana o kēia lā, ʻo ka pahuhopu hope o ke kaua kumukūʻai e hoʻopōʻino i ka hoa paio i hoʻokahi tausani a nalowale ʻewalu haneli.Ma ka hilinaʻi wale ʻana i ka ʻenehana ʻokiʻoki e ʻike i kahi ala i waho a hoʻokumu i ka ʻokoʻa huahana hiki iā mākou ke hopu i nā manawa mākeke hou.
E hoʻolohe i ka ʻenehana hou o ka uhi kaʻa a hopu i ka holo ʻoihana
ʻO ka uhi kaʻa, e like me kā mākou e ʻike ai, he anti-scratch, waimaka-kūʻai, a me nā hiʻohiʻona ʻē aʻe.Loaʻa kēia mau hiʻohiʻona mai ke kāʻei TPU o ka uhi kaʻa.ʻO kahi uhi kaʻa mea TPU maikaʻi e pale pono i ka ʻili pena a he lōʻihi kona ola.ʻO kekahi hana koʻikoʻi o ka uhi kaʻa ʻo ka hoʻomaʻemaʻe ponoʻī, hoʻoponopono ponoʻī, a me ka hoʻomālamalama kiʻekiʻe.Loaʻa kēia mau hana mai ka uhi ʻana ma ka ʻili o ka substrate TPU.ʻO ka maikaʻi o kēlā papaʻaʻole wale nō e wehewehe i ka hana hoʻomaʻemaʻe pono'ī nui, akā,ʻo ia kekahi o nā mea nui loa i ka hoʻoholoʻana i keʻano o ke kaʻa.ʻO ka hopena, ke kūʻai nā mea kūʻai aku i nā lole kaʻa no ka mālama ʻana i ke ʻano o ke kaʻa i kēlā me kēia lā, e nānā nui lākou i ka hana hoʻomaʻemaʻe ponoʻī o ka uhi.
Aia ka ʻokoʻa ma waena o ka pili a me ka mamao, a ʻoi aku ka maoli o ka uhi kaʻa hydrophobic coating!
Nui nā uhi kaʻa i ʻike ʻole ʻia e hoʻolaha ʻia he hana hoʻomaʻemaʻe ponoʻī, akā aia kahi nīnau e pili ana i ka hopena.ʻO ka nui o nā hale kūʻai kiʻiʻoniʻoni pono e kōkua i ka hoʻomaopopo ʻana.Aia nā ʻano hydrophilic a me ka hydrophobic o nā uhi kaʻa ʻike ʻole.I kēia lā e kamaʻilio mākou e pili ana i kēia ʻokoʻa pili pili.
Loaʻa kekahi mau mea kaʻa i ke kaʻina hana ma hope o ka loaʻa ʻana o ka ua i ka wā e haʻalele ai ka wai, e ʻike ʻia nā kiko ua ʻeleʻele a keʻokeʻo paha ma ka ʻili o ke kaʻa ʻike ʻole ʻia, e like me ke kiʻi ma lalo nei.
Wahi a ka poʻe i loko o ka ʻoihana, ʻo ke kumu nui o kēia, ʻaʻole hydrophobic ka uhi ʻana o ka ʻaʻahu kaʻa, no laila pili nā kulu wai i ke kapa kaʻa a ʻaʻole kahe i lalo.Ke hoʻoheheʻe ʻia ka wai, hana ʻia nā mea i koe i nā kaha wai, nā ʻili wai, a me nā ʻāpana ua.Inā ʻaʻole lawa ka compactness o ka uhi.I kēlā kūlana, e komo pū nā mea koena i loko o ka membrane, e hopena i nā ʻili ua hiki ʻole ke holoi ʻia a holoi ʻia paha, e hōʻemi loa i ke ola lawelawe o ka membrane.
He hydrophilic a hydrophobic paha ka uhi kaʻa?Pehea e ʻokoʻa ai kēia?
Ma mua o ke aʻo ʻana i ka ʻokoʻa, pono mākou e hoʻomaopopo mua i ka manaʻo o ka hydrophilic a me ka hydrophobic.
ʻO ka microscopically, ʻo ka huina pili ma waena o kahi kulu wai a me ka ʻili membrane e hoʻoholo inā he hydrophilic a hydrophobic paha.He hydrophilic ka huina pili ma lalo o 90°, he hydrophilic ka huina pili ma lalo o 10°, he hydrophobic ka huina pili i ʻoi aku ma mua o 90°, a ʻo kahi kihi pili ma mua o 150° he Super-hydrophobic.
ʻO ka mea huna o ka hydrophobic layer o ke kiʻi pale (2) Ma ke ʻano o ka uhi ʻana o ka uhi kaʻa, inā e hana ʻia ka hopena hoʻomaʻemaʻe ponoʻī.He hopena kūpono ia ma ke kumumanaʻo, inā paha e hoʻomaikaʻi i ka hydrophobicity a i ʻole ka hydrophobicity.ʻO ka hopena hoʻomaʻemaʻe ponoʻī, ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka maikaʻi loa inā ʻoi aku ka liʻiliʻi o ka angle contact hydrophilic ma mua o 10 degere, a ʻaʻole pono e hoʻonui ʻia ka ʻili hydrophobic e hana i kahi hopena hoʻomaʻemaʻe ponoʻī.
Ua hana kekahi mau ʻoihana i nā hoʻokolohua helu.ʻO ka hapa nui o nā ʻaʻahu kaʻa ma ka mākeke i kēia lā he hydrophilic coatings.Ma ka manawa like, ua ʻike ʻia ʻaʻole hiki ke loaʻa i nā ʻaʻahu kaʻa o kēia manawa ke loaʻa ka super hydrophilicity o 10 °, a ʻo ka hapa nui o nā kihi pili he 80 ° -85 °, me ka liʻiliʻi loa o ka huina pili he 75 °.
ʻO ka hopena, hiki ke hoʻomaikaʻi ʻia ka hopena hoʻomaʻemaʻe ponoʻī o ka uhi kaʻa hydrophilic o ka mākeke.ʻO kēia no ka mea, ma hope o ka hoʻopili ʻana i ka uhi kaʻa ʻike ʻole hydrophilic, piʻi ka ʻāpana o ke kino e pili ana i ka wai i nā lā ua, e hoʻonui ana i ka nui o nā stains a pili i ka ʻili pena, he paʻakikī ke hoʻomaʻemaʻe.
Wahi a ka poʻe loea, ʻoi aku ka maʻalahi o ke kaʻina hana o ka hydrophilic coatings a ʻoi aku ka maikaʻi ma mua o ka hydrophobic coatings.ʻO ka hoʻohālikelike ʻana, pono ka uhi ʻana o ka hydrophobic i ka hoʻokomo ʻana i nā meaʻai oleophobic nano-hydrophobic, a paʻa loa nā koi o ke kaʻina hana, ʻaʻole hiki i ka hapa nui o nā ʻoihana ke hoʻokō - no laila ke kaulana o ka ʻaʻahu wai.
Eia nō naʻe, loaʻa i ka uhi kaʻa hydrophobic nā pono kūʻokoʻa i ka hoʻoponopono ʻana i ka pilikia o ka hopena hoʻomaʻemaʻe ponoʻī o nā uhi kaʻa ʻike ʻole ʻia no ka mea ua like ka hopena o ka uhi hydrophobic me ka hopena lau lotus.
ʻO ka mea huna o ka hydrophobic layer o ke kiʻi pale (3) ʻO ka hopena o ka lau lotus ma hope o ka ua, ʻo ka microscopic microscopic morphology a me ka epidermal wax ma ka lau lotus e pale i nā kulu wai mai ka pālahalaha ʻana a me ka adsorbing ma ka ʻili o ka lau, akā e hana i nā kulu wai.I ka manawa like, wehe ia i ka lepo a me ka lepo mai nā lau.
ʻO ka mea huna o ke kiʻi pale hydrophobic layer (4)
Ke kau ʻia ma luna o ka ʻaʻahu kaʻa hydrophobic, hōʻike ʻia i ka wā e hāʻule ai ka wai ua ma luna o ka ʻili o ka membrane, hana ia i nā kulu wai ma muli o ke ʻano o ka ʻili o ka hydrophobic coating.E paheʻe wale nā kulu wai a haʻalele i ka ʻili membrane ma muli o ka umekaumaha.Hiki i nā kulu wai ʻōwili ke wehe i ka lepo a me ka ʻōpala mai ka ʻili o ka membrane, e hana ana i kahi hopena hoʻomaʻemaʻe ponoʻī.
Pehea e ʻike ai inā he hydrophilic a i ʻole hydrophobic ka uhi kaʻa?
ʻElua mau ala nui:
1. E hoʻohana i nā mea ʻoihana e ana i ke kihi pili.
2. ʻOlokaʻi ʻia ka wai ma ka ʻili o ka membrane e hana i kahi loiloi mua.
Hoʻopili maʻalahi nā kulu wai ma ka ʻili hydrophilic maʻamau.ʻAʻole e hana ʻia nā kulu wai ma kahi ʻili hydrophilic.ʻO ka ʻili wale nō ka maʻa;E ulu ana nā kulu wai ma nā wahi hydrophobic, akā e kahe ana lākou me ka umekaumaha., hoʻohui a neʻe aku, maloʻo ka ʻili, a ʻoi aku ka ikaika o ka hopena super-hydrophobic.
ʻO ka hopena, ke kau ʻia ka wai ma luna o ka ʻaʻahu kaʻa, hoʻopuehu ʻia nā ʻōpala, paʻakikī ke kahe, a ʻo ka hapa nui o ia mea he uhi hydrophilic.Huli nā kulu wai a lele aku, e hōʻike ana i ka ʻili, ka mea i uhi nui ʻia i nā uhi hydrophobic.
