Nā manaʻo hoʻomohala e hiki mai ana o ka pena hydrophobic

Hōʻike pinepine ka pena Hydrophobic i kahi papa o nā uhi ikehu haʻahaʻa kahi i ʻoi aku ka nui o ke kihi pili wai θ o ka uhi ʻana ma kahi ʻili maʻemaʻe ma mua o 90°, ʻoiai ʻo ka pena superhydrophobic he ʻano hou o ka uhi ʻana me nā waiwai ili kūikawā, ʻo ia hoʻi ka pili wai me he uhi paa. ʻOi aku ka nui o ka huina ma mua o 150° a ʻo ia hoʻi, ʻoi aku ka liʻiliʻi o ke kihi pili wai ma lalo o 5°. Mai 2017 a 2022, e ulu ana ka mākeke pena hydrophobic i ka nui o ka ulu makahiki o 5.5%. Ma 2017, ʻo ka nui o ka mākeke o ka pena hydrophobic he 10022.5 tons. I ka makahiki 2022, e piʻi ka nui o ka mākeke o ka pena hydrophobic i 13,099 tons. ʻO ka ulu ʻana o ka noi o ka mea hoʻohana hope a me ka hana maikaʻi o ka pena hydrophobic i alakaʻi i ka hoʻomohala ʻana o ka mākeke pena hydrophobic. ʻO ka ulu ʻana o kēia mākeke e hilinaʻi nui i ka ulu ʻana o nā ʻoihana mea hoʻohana hope e like me ka automotive, kūkulu hale, moana, aerospace, olakino a me nā uila.

Ma muli o ka ulu ʻana o ka ʻoihana kūkulu hale, manaʻo ʻia ka pena hydrophobic i hoʻohana ʻia no nā substrates concrete e hōʻea i ka helu kiʻekiʻe o ka ulu ʻana o ka hui i ka wā wānana. Hoʻohana ʻia nā pena hydrophobic ma luna o ke kaʻa e pale aku i ka pehu ʻana o ka ʻiʻo, ka pohā, ka scaling, a me ka ʻoki ʻana. Ke pale nei kēia mau pena hydrophobic i ka ʻili ʻili ma ka hoʻonui ʻana i ke kihi pili o nā kulu wai me ka ʻili.

I ka wā wānana, e lilo ke kaʻa i ka ʻoihana ʻoihana wikiwiki loa i ka mākeke pena hydrophobic. ʻO ka hoʻonui ʻana i ka hana kaʻa e alakaʻi i ka noi o ka ʻoihana kaʻa no ka pena hydrophobic.

I ka makahiki 2017, e noho ka ʻāina ʻo Asia-Pākīpika i ka hapa nui o ka mākeke pena hydrophobic, a ukali ʻia e ʻAmelika ʻAmelika. ʻO kēia ulu kiʻekiʻe ma muli o ka piʻi nui ʻana o ka noi no nā kaʻa i ka ʻāina, ka piʻi nui ʻana o ka ʻoihana aerospace, a me ka piʻi nui ʻana o nā ʻoihana hoʻomaka i ka ʻoihana olakino.

Manaʻo ʻia nā hoʻoponopono o ke kaiapuni he mea paʻa nui i ka mākeke coating hydrophobic. Hoʻomohala kekahi mau mea hana i nā huahana hou i mea e hoʻokūkū ai i ka mākeke, akā i ka manawa like e hoʻokō ai i nā lula palekana kaiapuni e lawe i ka manawa a me ka hoʻoikaika.

Hiki ke hoʻokaʻawale ʻia nā ʻano o ka pena pena hydrophobic: pena hydrophobic-based polysiloxane, pena hydrophobic-based fluoroalkylsiloxane, pena hydrophobic based fluoropolymer, a me nā ʻano ʻano ʻē aʻe. Hoʻohana nui ʻia lākou i ke kūkulu ʻana, nā hale ʻenekinia, nā kaʻa, nā mokulele, a me nā ʻoihana ʻē aʻe. . Hiki ke hoʻokaʻawale ʻia ke kaʻina hana uhi hydrophobic i ka hoʻoheheʻe ʻana i ka mahu, ka hoʻokaʻawale microphase, sol-gel, electrospinning, a me ka etching. Hiki ke hoʻokaʻawale ʻia ka pena hydrophobic i loko o ka hoʻomaʻemaʻe ponoʻī ʻana i ka hydrophobic pena, anti-fouling hydrophobic coatings, anti-icing hydrophobic coatings, anti-bacterial hydrophobic paint coatings, corrosion-resistant hydrophobic paint coatings, etc.
