Yam dab tsi yuav cuam tshuam qhov kev ua tau zoo ntawm Teflon daim kab xev

Lub adhesion kev ua tau zoo ntawm Teflon daim kab xev yog cuam tshuam los ntawm tej yam xws li kub, av noo, tshuaj lom neeg tshaj tawm, thiab ultraviolet hluav taws xob, tshwj xeeb tshaj yog kub, high humidity, thiab ultraviolet hluav taws xob. Yog tias cov nplaum raug raug rau qhov chaw kub kub, nws yuav dhau mus rau qee qhov kev puas tsuaj, thiab tom qab kev ntsuas kub siab, nws cov khoom siv tshuab yuav txo qis; Tom qab thermal aging, cov khoom siv kho tshuab yuav txo qis, yog li cuam tshuam rau cov nplaum ua haujlwm.

Adhesives kuj tuaj yeem txo lawv lub zog sib txuas hauv qhov chaw ntub dej, vim qee yam tshuaj lom neeg ntawm cov nplaum tau yooj yim hydrolyzed. Cov qauv tshuaj, hom catalyst, ntau npaum li cas, thiab yooj yim ntawm cov nplaum substrate tuaj yeem cuam tshuam tus nqi ntawm hydrolysis. Tsuas yog los ntawm kev xaiv qhov tsim nyog ntawm cov khoom siv hauv paus thiab catalyst tuaj yeem txhim kho lub zog nplaum.

Txhawm rau kom tsis txhob muaj kev cuam tshuam ntawm ib puag ncig, yog tias cov nplaum siv rau hauv ib puag ncig hnyav, kev simulation ib puag ncig yuav tsum tau ua, thaum ua kom ntseeg tau tias cov nplaum nplaum tuaj yeem tiv thaiv sab nraud. Qhov saum npoo roughness thiab contour ntawm cov khoom nplaum yuav muaj kev cuam tshuam rau lub zog sib txuas ntawm PTFE daim kab xev. Thaum lub sij hawm sib txuas cov txheej txheem, lub sij hawm, qhov kub thiab txias, siab, thiab qhov chaw paug tuaj yeem cuam tshuam rau kev sib koom ua ke thiab kev ua tau zoo. Piv txwv li, qhov kub tsis tshua muaj peev xwm ua rau daim kab xev nyuaj thiab nkig, ua rau muaj kev ntxhov siab ntau ntxiv, thiab daim kab xev kuj tseem ua rau deformation ntawm qhov kub qis, ua rau nws nyuaj kom tau txais cov khoom siv kho tshuab ruaj khov; Kev kub siab tuaj yeem yooj yim soften daim kab xev thiab txo nws lub zog shear. Txhawm rau txhim kho thiab txhim kho kev ua tau zoo thiab kev ua haujlwm ntawm Teflon daim kab xev, thiab txhawm rau txuas nws lub neej kev pab cuam, nws yog ib qho tsim nyog yuav tsum zam kom tsis txhob muaj qhov tsis zoo thaum siv.
