Yam dab tsi yuav cuam tshuam rau kev sib raug zoo thiab kev ua haujlwm ntawm Teflon daim kab xev

Kev sib koom ua ke ntawm Teflon daim kab xev yog cuam tshuam los ntawm cov yam ntxwv xws li kub, av noo, tshuaj lom neeg tshaj tawm, thiab hluav taws xob ultraviolet, tshwj xeeb tshaj yog kub, av noo, thiab hluav taws xob ultraviolet. Yog tias cov nplaum raug rau qhov chaw kub kub, nws yuav dhau mus rau qee qhov kev degradation, 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 kev sib koom ua ke. Lub sij hawm ntev raug rau ultraviolet hluav taws xob tuaj yeem ua rau tsis muaj xim, embrittlement, thiab tshuaj lom neeg decomposition ntawm daim kab xev nplaum, uas tuaj yeem cuam tshuam kev sib raug zoo thiab kev siv tau zoo.

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 qhov yooj yim ntawm cov nplaum substrate tuaj yeem cuam tshuam rau tus nqi hydrolysis. Tsuas yog los ntawm kev xaiv tus nqi tsim nyog ntawm cov khoom siv hauv paus thiab catalyst tuaj yeem txhim kho kev sib raug zoo. 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 tseem ua kom ntseeg tau tias cov nplaum nplaum tuaj yeem tiv thaiv sab nraud. Qhov saum npoo roughness thiab contour ntawm cov khoom coated yuav muaj kev cuam tshuam rau lub zog adhesion ntawm Teflon 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, exacerbating kev ntxhov siab concentration, thiab daim kab xev yog nquag deformation ntawm qhov kub thiab txias, ua rau nws nyuaj rau kom tau txais cov neeg 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 sib raug zoo thiab cov txiaj ntsig ntawm Teflon daim kab xev, nrog rau nws lub neej kev pab cuam, tsuas yog los ntawm kev zam kom tsis txhob muaj teeb meem tshwm sim thaum siv nws tuaj yeem txhim kho.
