Dab tsi yog qhov txawv ntawm Nto Tension thiab Interfacial Tension?

Peb tshwj xeeb hauv kev tsim khoomnto nro testers(tseem hu ua tag nrho tsis siv neeg nto nro testers) nyob rau hauv ultra-high voltage. Tom ntej no, peb yuav qhia rau koj txog qhov sib txawv ntawm qhov nro ntawm lub ntsej muag thiab lub ntsej muag sib txawv?
Nto nro yog tus yam ntxwv ntawm kev sib cuag ntawm cov kua thiab roj theem (feem ntau yog cua). Ntawm qhov tod tes, interfacial nro yog tus yam ntxwv ntawm ob yam khoom. Nws tuaj yeem ua kua ua kua, kua dej, lossis cov khoom cua.
Cov cim qhia rau saum npoo thiab qhov nro interfacial σ Nws yog ntsuas raws li lub zog ntawm ib chav tsev ntev. Nws chav tsev SI yog millinewtons ib 'meter' (mN / m), uas yog sib npaug rau cov feem ntau siv cgs unit, dynes ib centimeter (dynes / cm).
Yuav kom nkag siab txog lub hauv paus chiv keeb ntawm qhov nro ntawm qhov chaw thiab qhov nro ntawm lub ntsej muag, peb yuav tsum nkag siab txog ob nqe lus; Cohesion thiab adhesion.
Cohesion yog kev sib cuam tshuam ntawm cov molecules zoo sib xws
Cohesion yog qhov attraction ntawm molecules uas zoo sib xws. Cohesion yog lub zog intermolecular uas ua rau cov kua los tiv thaiv kev sib cais. Piv txwv li, nyob rau hauv dej, muaj zog cohesion thiab hydrogen bonding, ua rau cov dej los nag poob nyob rau hauv daim ntawv ntawm tee me ntsis pos huab.
Lub cohesive quab yuam ntawm molecules yog ua rau saum npoo nro. Xwb, cov rog no tsis sib npaug vim tias muaj tsawg dua cov molecules nyob ib sab ntawm qhov chaw piv rau cov kua hauv lub cev.
Lub cohesive quab yuam ntawm cov khib nyiab muaj zog heev uas lawv tsis lo rau cov ntaub ntawv uas lawv tuaj cuag. Ntawm qhov tod tes, cov kua dej xws li dej kuj muaj adhesion, tso cai rau lawv cuam tshuam nrog lwm cov kua thiab cov khib nyiab.
Adhesion yog kev sib cuam tshuam ntawm cov molecules sib txawv
Adhesion yog kev sib cuam tshuam ntawm cov molecules sib txawv. Adhesion yog tshwm sim los ntawm lub zog ua ntawm ob lub substrates, xws li mechanical force thiab electrostatic force. Thaum ob cov kua dej tsis sib haum tuaj rau hauv kev sib cuag, adhesion yuav siv tau. Thaum cov kua nkag mus rau hauv cov khoom, adhesion tseem ceeb heev.
Nto thiab interfacial nro yog qhov tseem ceeb hauv ntau daim ntawv thov kev lag luam
Nto nro thiab interfacial nro yog qhov tseem ceeb hauv ntau daim ntawv thov kev lag luam. Piv txwv li, ntsuas qhov nro thaum txiav txim siab qhov tseem ceeb micelle concentration yog qhov tsim nyog. Ntawm qhov tod tes, interfacial nro yog ib qho tseem ceeb parameter ntawm lotion stability.
