Kauv welded yeeb nkabKev sib txhuam adhesion txoj kev xav tam sim no tau txais dav, nyob rau hauv qhov kev sib txhuam zoo li qub, qhov chaw sib cuag tiag tiag yog proportional rau lub load.Thiab thaum zawv zawg kev sib txhuam, peb yuav tsum xav txog lub xub ntiag ntawm shear quab yuam, tom qab ntawd, nce kauv hlau qhov chaw sib cuag tau los ntawm qhov qub load thiab shear load rau kev sib xyaw ua ke ntawm.Nws kuj tseem tuaj yeem hais tias qhov taw qhia tawm ntawm kev sib cuag tshwm sim, nrog rau kev ntxhov siab los ntawm kev ua haujlwm ib txwm muaj thiab cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob los ntawm kev cuam tshuam los ntawm shear stress.

Thaum muab kauv welded yeeb nkab yog kev sib txhuam nyob rau hauv cov huab cua, muaj ib tug natural pollution vim lub nto daim nyias nyias, nws yog tsim nyog los siv kev sib txhuam phenomenon contaminated zaj duab xis adhesion theories muaj nyob rau piav qhia cov hlau nto.Nyob rau hauv qhov tseeb, feem ntau ntawm cov hlau nto yog ib txwm them nrog ib tug nyias oxide zaj duab xis, thiab yog li no kev sib txhuam rau hlau kev sib txhuam, kev sib txhuam ntawm cov oxide zaj duab xis yog qhov tseem ceeb ntawm oxide zaj duab xis, tom qab kev puas tsuaj ntawm oxide zaj duab xis tsuas yog ua tau ncaj qha rau ntawm daim duab. hlau-rau-hlau sib txhuam.Thaum tsis muaj kev sib txhuam ntawm qhov chaw tsis muaj paug, thiab kev sib kis ntawm cov membrane shear zog, adhesion junction kev loj hlob tsis pom tseeb.Thaum cov kauv steel yeeb nkab thaum membrane fouling shear kev nyuaj siab ncav cuag lub zog shear ntawm cov pa phem membrane nto zaj duab xis raug txiav, kev sib txhuam pib swb.Nyob rau hauv cov ntaub ntawv no, cov nplaum sib txhuam coefficient yuav qhia tau hais tias f = k / v qhov twg, rau lub zog shear ntawm nto paug zaj duab xis yog lub yield point ntawm lub cev hlau.
