Kunama kunonyungudika kunopisa kunoburitsa sei kunamira?

Zvizhinji zvehotmelt adhesivezvinhu zvakasimba uye hazvina kunamira patembiricha yepakamuri.Sei chinonamira chinopisa chinonyunguduka chichinamira mushure mekupisa?

Zvinoenderana neruzivo rwazvino uye zvidzidzo zvakapfuura. Kune dzinenge mbiri dzidziso: imwe maonero ndeokuti theviscosity inotemerwa nehunhu hwemuviri weaviri masisitimu ekunamira; imwe maonero ndeyekuti viscosity inotarirwa neiyo viscoelastic deformation maitiro. Parizvino, kune vanhu vakawanda vanotsigira maonero ekupedzisira. Nekuti dzidziso ye viscoelasticity inogona kutsanangura zvimwe zvekuedza chokwadi.

 

Viscoelasticity ibazi rekutsvagisa resolid mechanics, inozivikanwawo se rheology. Iyo yakavakirwa pane elastic zvivakwa uye viscous zvimiro zvezvishandiso kudzidza kugoverwa kwemukati uye kuomarara kwezvinhu uye hukama pakati pavo nekunze kwesimba. Iyo viscous chimiro chechinhu chinonyanya kuenderana nekunetseka uye strain mwero muzvinhu, uye viscoelastic muviri unogona kunzwisiswa semusanganiswa we elastomer uye mvura.
