Granite yog ib hom pob zeb igneous uas paub txog nws qhov ruaj khov, tawv, thiab tiv taus corrosion. Vim yog cov yam ntxwv no, nws tau dhau los ua cov khoom siv nyiam siv rau hauv ntau yam kev siv hauv kev lag luam. Ib qho ntawm cov ntawv thov no yog nyob rau hauv kev tsim cov LCD panels. Muaj ntau qhov zoo ntawm kev siv cov khoom granite hauv cov khoom siv rau kev tsim LCD vaj huam sib luag, uas peb yuav tham txog ntau yam hauv qab no.
Ua ntej, granite yog ib yam khoom ruaj khov heev uas muaj qhov coefficient qis ntawm thermal expansion. Qhov no txhais tau tias nws tsis nthuav dav lossis cog lus ntau txawm tias raug rau qhov kub siab lossis thaum muaj kev hloov pauv ntawm qhov kub. Qhov no yog ib qho tseem ceeb ntawm cov khoom siv hauv LCD vaj huam sib luag tsim khoom siv vim tias cov vaj huam sib luag yuav tsum tau sib dhos kom raug thaum lub sijhawm tsim khoom. Kev ruaj khov ntawm cov khoom granite ua kom ntseeg tau tias qhov sib dhos tau tswj hwm kom raug, ua rau cov vaj huam sib luag LCD zoo.
Qhov thib ob, granite yog ib yam khoom tawv uas tiv taus kev hnav thiab tsim kua muag los ntawm kev siv tas li. Hauv kev tsim cov LCD panels, cov khoom siv siv tas li, thiab txhua yam kev hnav thiab tsim kua muag tuaj yeem ua rau cov vaj huam sib luag tsis meej. Cov khoom granite tuaj yeem tiv taus kev siv ntev yam tsis muaj kev puas tsuaj loj, kom ntseeg tau tias cov khoom siv tuaj yeem tswj tau nws qhov tseeb thiab qhov tseeb.
Qhov thib peb, granite yooj yim rau kev siv tshuab vim nws cov khoom siv lub cev. Nws muaj peev xwm tsim cov qauv tsim thiab cov duab zoo nkauj uas yog qhov tseem ceeb rau cov txheej txheem tsim khoom LCD. Qib kev ywj pheej thiab kev siv tau yooj yim no ua rau cov khoom siv uas tau kho kom haum rau cov kev xav tau tshwj xeeb.
Qhov thib plaub, cov khoom granite tiv taus cov kua qaub thiab alkaline heev. Lawv tsis muaj zog thiab tsis ua haujlwm nrog cov tshuaj feem ntau pom hauv cov txheej txheem tsim khoom LCD. Qhov kev tiv thaiv no ua kom cov khoom siv tseem ua haujlwm tau zoo thiab tsis raug kev puas tsuaj ua ntej lossis hnav thiab tsim kua muag.
Thaum kawg, cov khoom granite muaj zog heev thiab tuaj yeem tiv taus cov qib siab thiab lub zog. Thaum lub sijhawm tsim cov vaj huam sib luag LCD, cov khoom siv raug rau ntau yam kev ntxhov siab, thiab qhov ua tau zoo ntawm cov khoom granite ua kom lawv tsis tawg lossis ua tsis tiav. Qhov no ua rau lub sijhawm ua haujlwm ntau dua thiab txo cov nqi txij nkawm.
Xaus lus, qhov zoo ntawm kev siv cov khoom granite hauv cov khoom siv rau kev tsim LCD vaj huam sib luag muaj ntau yam. Qhov ruaj khov, kev ruaj khov, thiab kev tiv taus kev hnav thiab tsim kua muag, cov kua qaub thiab alkalis ua rau lawv yog cov khoom siv zoo tshaj plaws rau kev siv hauv cov txheej txheem tsim LCD uas muaj kev rhiab heev thiab raug. Cov khoom kawg tsim tawm yog qhov zoo, raug, thiab meej, uas ua rau txo qhov tsis zoo thiab ua kom muaj txiaj ntsig zoo dua hauv cov txheej txheem tsim khoom.
