Kev tsim kho yav tom ntej ntawm cov xim hydrophobic

Cov xim hydrophobic feem ntau xa mus rau cov chav kawm ntawm cov txheej txheem ntawm lub zog qis uas cov dej zoo li qub sib cuag lub kaum sab xis θ ntawm cov txheej txheem ntawm qhov chaw du yog siab dua 90 °, thaum cov xim superhydrophobic yog hom tshiab txheej txheej nrog cov khoom tshwj xeeb, lub ntsiab lus dej sib cuag nrog ib txheej txheej. Lub kaum sab xis yog ntau dua 150 ° thiab feem ntau txhais tau tias cov dej sib cuag lub kaum sab xis yog tsawg dua 5 °. Los ntawm 2017 txog 2022, lub lag luam xim hydrophobic yuav loj hlob ntawm ib qho kev loj hlob txhua xyoo ntawm 5.5%. Hauv xyoo 2017, kev lag luam loj ntawm cov xim hydrophobic yuav yog 10022.5 tons. Xyoo 2022, kev lag luam loj ntawm cov xim hydrophobic yuav ncav cuag 13,099 tons. Kev loj hlob ntawm cov neeg siv kawg xav tau thiab kev ua tau zoo ntawm cov xim hydrophobic tau tsav txoj kev loj hlob ntawm kev lag luam xim hydrophobic. Kev loj hlob ntawm kev lag luam no feem ntau yog nyob ntawm kev loj hlob ntawm cov neeg siv khoom lag luam xws li tsheb, kev tsim kho, marine, aerospace, kev kho mob thiab hluav taws xob.

Vim muaj kev loj hlob ntawm kev tsim kho kev lag luam, cov xim hydrophobic siv rau cov pob zeb substrates yuav tsum ncav cuag qhov siab tshaj plaws kev loj hlob ntawm lub sijhawm kwv yees. Cov xim hydrophobic yog siv rau ntawm pob zeb kom tsis txhob muaj pob zeb o, tawg, scaling, thiab chipping. Cov xim hydrophobic no tiv thaiv cov pob zeb nto los ntawm kev ua kom lub kaum sab xis ntawm cov dej ntws nrog cov pob zeb ua kom zoo.

Thaum lub sijhawm kwv yees, lub tsheb yuav dhau los ua qhov kev lag luam loj tshaj plaws hauv kev lag luam xim hydrophobic. Kev nce hauv tsheb ntau lawm yuav ua rau kev lag luam tsheb xav tau rau cov xim hydrophobic.

Hauv 2017, thaj av Asia-Pacific yuav tuav qhov loj tshaj plaws ntawm kev lag luam xim hydrophobic, ua raws li North America. Qhov kev loj hlob siab no yog vim muaj kev xav tau ntau ntxiv rau tsheb hauv cheeb tsam, kev lag luam aerospace kev lag luam nce ntxiv, thiab cov tuam txhab pib ua lag luam nce ntxiv hauv kev lag luam khoom siv kho mob.

Cov kev cai ib puag ncig raug suav hais tias yog ib qho kev txwv loj hauv kev lag luam hydrophobic xim txheej. Qee cov tuam txhab tsim cov khoom tshiab txhawm rau kom muaj kev sib tw hauv kev ua lag luam, tab sis tib lub sijhawm ntsib kev tiv thaiv ib puag ncig yuav siv sijhawm thiab siv zog.

Cov hom xim hydrophobic xim txheej tuaj yeem muab faib ua: polysiloxane-based hydrophobic xim, fluoroalkylsiloxane-based hydrophobic xim, fluoropolymer-based hydrophobic xim, thiab lwm yam. Lawv tau siv dav hauv kev tsim kho, engineering chaw, tsheb, aviation, thiab lwm yam. . Cov txheej txheem hydrophobic tuaj yeem muab faib ua cov tshuaj vapor deposition, microphase cais, sol-gel, electrospinning, thiab etching. Cov xim hydrophobic tuaj yeem muab faib ua tus kheej-tu hydrophobic xim coatings, anti-fouling hydrophobic coatings, anti-icing hydrophobic coatings, anti-bacterial hydrophobic xim txheej, corrosion-resistant hydrophobic xim txheej, thiab lwm yam raws li lawv cov khoom.
