Ob npaug - satid kab xev yog cov khoom siv nplaum uas muaj ntau. Nws lub hauv paus kev ua haujlwm yog raws li cov khoom siv lub cev thiab tshuaj ntawm cov ntaub ntawv PCOlastic, khov kho ob qhov chaw ua ke los ntawm nruab nrab nruab nrab.
Kev tsim qauv, ob npaug {- sidles cov txheej txheem, thiab cov khoom siv hauv qab, ua npuas dej, lossis tsis muaj ntaub qhwv) nyob hauv nruab nrab. Cov nplaum yog cov tseem ceeb tivthaiv uas ua rau adhesion, thiab nws cov nplaum stems los ntawm kev sib txuam. Thaum ob npaug {{4 4} ated Salp yog thov rau ib qho khoom, suav nrog cov kev tawm tsam, thiab kev tawm tsam) nrog cov lwg me me ntawm cov nplaum. Hydrogen Bonds lossis cov neeg siv tshuaj yuav ua tau, ua rau muaj zog adhesion.
Tus txheej txheem nplaum ntawm ob - satas daim kab xev tuaj yeem faib ua ob theem: pib tack thiab kawg tack. Thaum pib sib tw txuas ntxiv rau cov nplaum thawj zaug sib cuag nrog cov nplaim thiab yog feem ntau nyob ntawm cov nplaum muaj kua thiab nplaim taws. Raws li ob npaug - Sided daim kab xev yog nias rau hauv qhov chaw me me, nce thaj chaw ze thiab txhim kho adhesion. Cov khaub ncaws zaum kawg tshwm sim tom qab lub sijhawm, thaum cov nplaum lwg me me ua ib qho kev sib tw sib luag nrog cov khoom ua kom ruaj khov. Qhov no feem ntau yuav siv sijhawm ntau teev lossis ntev ntev mus txog qhov kawg siab tshaj plaws.
Tsis tas li ntawd, cov nplaum lub intermediate substrate beferences nws ua tau zoo. Piv txwv li, ua npuas ncauj - raws li ob npaug- nqus dej thiab poob siab, ua rau nws haum rau qhov chaw tsis sib xws; Zaj duab xis- raws li ob npaug {{4} ated
Hauv ntej, ob npaug {- sidose-sed kab ruaj ntseg txuas ob thaj chaw los ntawm kev kos duab lub cev thiab, yog tias tsim nyog, tshuaj lom neeg. Nws txoj haujlwm ua haujlwm nyob ntawm tsis yog nyob ntawm cov khoom siv tau txais cov khoom uas muaj xws li qhov kub thiab txias, thiab qhov huv si ntawm cov adherend nto.
