Kudzidza kwe Superhydrophobic Biomimetic Surfaces
Nzvimbo dzepamusoro dzezvinhu dzakakosha zvakanyanya, uye vaongorori vanoedza marudzi ese enzira dzekuwana zvinhu zvemukati zvine zvivakwa zvinodiwa. Nekuvandudzwa kweiyo bionic engineering, vaongorori vari kubhadhara zvakanyanya kutarisisa kune biological surface kuti vanzwisise kuti zvisikwa zvingagadzirisa sei matambudziko einjiniya. Ongororo yakadzama pamusoro pebiological surfaces yakaratidza kuti nzvimbo idzi dzine zvinhu zvakawanda zvisina kujairika.

Superhydrophobic Surface Inogona Kugadzirirwa neNzira mbiri
Vanhu vanoziva yekuzvichenesa lotus mhedzisiro kwemakore mazhinji, asi havagone kugadzira iyo zvinhu sezvo shizha relotus rinotarisana. Nemasikirwo, iyo yakajairwa superhydrophobic pamusoro - ongororo yakawana kuti shizha relotus, rakavakwa neakakosha geometry yekukwasha mupasi pevhu simba rakasimba repamusoro rinoita basa rakakosha pane superhydrophobic.Kubva pane idzi nheyo, masayendisiti akatanga kutevedzera nzvimbo iyi. Ikozvino, kutsvagisa pane rough superhydrophobic pamusoro kwave kwakawanda kufukidzwa. Mune general, iyo superhydrophobic pamusoroVerenga Zvimwe…
Kuzvichenesa Effect yeSuper Hydrophobic Surface
Kunyorova chinhu chakakosha chenzvimbo yakasimba, iyo inotarirwa nekemikari yakagadzirwa uye morphology yepamusoro. Super-hydrophilic uye super hydrophobic pamusoro maitiro ndizvo zvikuru zviri mukati mezvidzidzo zvinopinda. Iyo superhydrophobic (inodzivirira mvura) pamusoro pejenirally inoreva pamusoro pekuti kona yekubata pakati pemvura nepamusoro inopfuura 150 degrees. Izvo vanhu vanoziva kuti superhydrophobic surface inonyanya kubva pamashizha emiti - lotus leaf surface, "kuzvichenesa" chiitiko. Semuenzaniso, madonhwe emvura anogona kukungurukaVerenga Zvimwe…

Super hydrophobic nzvimbo inogadzirwa neSuper hydrophobic coatings
Super-hydrophobic coatings inogona kugadzirwa kubva kune akawanda akasiyana zvinhu.

Ramangwana budiriro tarisiro ye hydrophobic pendi
Pendi yeHydrophobic inowanzoreva kirasi yeyakadzika pasi pesimba rejasi apo iyo yakadzika mvura yekubata angle θ yejasi pane yakatsetseka pendi yakakura kupfuura 90 °, nepo superhydrophobic pendi iri rudzi rutsva rwekupfeka neakakosha epamusoro zvivakwa, zvichireva kusangana nemvura chifukidzo chakasimba. Iyo kona ihombe kupfuura 150 ° uye kazhinji zvinoreva kuti mvura yekubata angle lag iri pasi pe5 °. Kubva 2017 kusvika 2022, iyo hydrophobic pendi musika ichakura paVerenga Zvimwe…
