Dab tsi yog cov yam ntxwv uas cuam tshuam rau kev hnav tsis kam ntawm hnav resistant ceramic coatings?

Hnav resistant ceramic txheej (epoxy resin adhesive txheej) muaj kev hnav zoo heev thiab yog siv dav hauv kev tiv thaiv cov khoom siv thiab kho qhov chaw, xws li cov khoom khawb, qhov tsis xws luag, cov kab nrib pleb sab nraud, ib feem hnav, thiab cov dej xau. Vim tias txoj haujlwm kho yog qhov yooj yim thiab kev lag luam thiab ua tau, cov txheej txheem no tau them nyiaj ntau dua los ntawm tib neeg.

Dab tsi yog yam uas cuam tshuam rau kev hnav tsis kam ntawm hnav-resistant ceramic coatings?

1. Tus nqi ntawm cov hmoov ntxiv:

Lub abrasion tsis kam ntawm txheej yog tsuas yog alumina ceramic hmoov. Thaum cov hmoov ntxiv rau hauv me me, muaj cov fulcrums tsawg dua los tiv thaiv kev puas tsuaj, thiab txheej txheej tsis tuaj yeem tiv thaiv tau zoo. Nrog rau qhov nce ntawm cov hmoov ntxiv, thaj tsam ntawm cov khoom siv ceramic yuav hnav tau nce, cov txheej tiv thaiv, thiab qhov hnyav vim hnav yog txo. Thaum cov hmoov cov ntsiab lus nce mus rau ib qho nyiaj, cov khoom hnav mus txog qib me me. Thaum cov hmoov ntau dhau ib qho nyiaj, qhov adhesion ntawm cov nplaum rau cov hmoov ceramic tsis txaus. Thaum raug kev sib txhuam quab yuam, vim tsis txaus shear lub zog, qee cov hmoov ceramic poob tawm tag nrho cov nplej, yog li lawv tsis tuaj yeem ua lub luag haujlwm ntawm kev hnav, thiab qhov hnyav poob hnyav. Ua kom muaj zog, hnav tsis kam ntawm cov txheej txheem txo.

2. Kev cuam tshuam ntawm hmoov particle loj ntawm hnav tsis kam

Thaum cov hmoov hmoov me me, qhov chaw sib cuag ntawm cov khoom thiab cov nplaum yog me me, thiab lub zog sib txuas tsis loj txaus. Cov khoom yog yooj yim poob tawm thaum lub sij hawm hnav. Raws li cov hmoov nplej nce, qhov chaw sib txuas ntxiv, qhov sib txuas ntawm qhov sib cais, thiab cov nplaum deforms thiab tawg. Txoj kev nyiam yog me me. Thaum lub particle loj ntawm cov hmoov mus txog ib tug npaum li cas, tus nqi ntawm abrasion maj mam txo. Tshaj ib qho me me, kev sib koom ua ke tsis xws luag xws li qhov pores nce ntxiv yuav txo qhov kev sib koom ua ke. Thaum lub sij hawm hnav, cov khoom siv ceramic loj yuav poob, thiab qhov hnav yuav nce siab heev. Cov txheej nplaum nplaum yuav tsis raug tiv thaiv thiab yuav hnav tawm. Yog li ntawd, cov khoom siv ceramic kuj tseem muaj kev cuam tshuam zoo rau kev hnav tsis kam, loj dhau lossis me me tsis tsim nyog.
