Lub hauv paus granite feem ntau siv rau hauv cov khoom siv semiconductor vim nws cov khoom siv zoo heev rau kev co, kev ruaj khov thermal, thiab cov coefficient qis ntawm thermal expansion. Txawm li cas los xij, zoo li lwm yam khoom siv, granites tuaj yeem tsim cov qhov tsis zoo uas tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov khoom siv semiconductor. Hauv tsab xov xwm no, peb yuav hais txog qee qhov tsis zoo ntawm lub hauv paus granite hauv cov khoom siv semiconductor thiab muab cov kev daws teeb meem.
Txhaum #1: Kev Hloov Pauv Ntawm Qhov Chaw
Qhov deformations ntawm qhov chaw yog qhov faults feem ntau hauv granite base hauv cov khoom siv semiconductor. Thaum lub granite base raug kev hloov pauv kub lossis cov khoom hnyav, nws tuaj yeem tsim cov deformations ntawm qhov chaw, xws li warps, twists, thiab bumps. Cov deformations no tuaj yeem cuam tshuam rau kev sib phim thiab qhov tseeb ntawm cov khoom siv semiconductor.
Kev daws teeb meem: Kev kho qhov chaw
Kev kho qhov chaw ntawm lub pob zeb granite tuaj yeem pab txo qhov kev puas tsuaj ntawm lub pob zeb granite. Cov txheej txheem kho yuav tsum tau rov sib tsoo lub pob zeb granite kom rov qab tiaj tus thiab du. Yuav tsum tau ua tib zoo xaiv cov cuab yeej sib tsoo thiab cov khoom siv sib tsoo kom raug kom ntseeg tau tias qhov tseeb raug tswj.
Qhov Txhaum #2: Kab nrib pleb
Cov kab nrib pleb tuaj yeem tshwm sim hauv lub hauv paus granite vim yog kev hloov pauv cua sov, cov khoom hnyav, thiab cov yuam kev ua haujlwm. Cov kab nrib pleb no tuaj yeem ua rau tsis ruaj khov ntawm cov qauv thiab cuam tshuam rau qhov tseeb ntawm cov khoom siv semiconductor.
Kev daws teeb meem: Kev sau thiab kho
Kev txhaws thiab kho cov kab nrib pleb tuaj yeem pab rov qab ruaj khov thiab raug ntawm lub hauv paus granite. Cov txheej txheem kho feem ntau yuav tsum tau txhaws qhov tawg nrog cov tshuaj epoxy resin, uas tom qab ntawd kho kom rov qab muaj zog ntawm qhov chaw granite. Tom qab ntawd qhov chaw sib txuas rov qab los zom kom rov qab tiaj tus thiab du.
Qhov Txhaum #3: Kev Ua Rau Delamination
Kev tawg yog thaum cov txheej ntawm lub hauv paus granite sib cais ntawm ib leeg, ua rau pom qhov sib txawv, cov qhov cua, thiab qhov tsis sib xws hauv qhov chaw. Qhov no tuaj yeem tshwm sim los ntawm kev sib txuas tsis raug, kev hloov pauv thermal, thiab kev ua yuam kev machining.
Kev daws teeb meem: Kev sib txuas thiab kho
Cov txheej txheem sib txuas thiab kho yuav siv cov epoxy lossis polymer resins los txuas cov ntu granite uas tawg lawm. Tom qab txuas cov ntu granite, qhov chaw kho yuav raug sib tsoo dua kom rov qab tiaj tus thiab du. Yuav tsum xyuas seb puas muaj qhov sib txawv thiab cov qhov cua seem ntawm cov granite kom paub tseeb tias lub hauv paus granite rov qab zoo li qub.
Qhov Txhaum #4: Kev Hloov Xim thiab Kev Pleev Xim
Qee zaum lub hauv paus granite tuaj yeem tsim cov teeb meem xim av thiab xim daj, efflorescence, thiab cov xim tsaus. Qhov no tuaj yeem tshwm sim los ntawm cov tshuaj lom neeg nchuav thiab kev ntxuav tsis zoo.
Kev daws teeb meem: Kev ntxuav thiab kev saib xyuas
Kev ntxuav granite tsis tu ncua thiab kom raug yuav pab tiv thaiv kom tsis txhob muaj xim thiab tsis muaj xim. Pom zoo kom siv cov tshuaj ntxuav pH nruab nrab lossis tsis muaj zog. Cov txheej txheem ntxuav yuav tsum ua raws li cov lus qhia ntawm cov chaw tsim khoom kom tsis txhob ua rau lub ntsej muag granite puas. Yog tias muaj xim tawv ncauj, siv cov tshuaj ntxuav granite tshwj xeeb.
Hauv kev xaus lus, lub hauv paus granite yog cov khoom siv ruaj khov thiab txhim khu kev qha uas siv dav hauv cov khoom siv semiconductor. Txawm li cas los xij, nws yuav tsim cov qhov tsis zoo raws sijhawm vim muaj kev hloov pauv kub, cov khoom hnyav, thiab cov yuam kev ua haujlwm. Yog tias muaj kev saib xyuas, kev ntxuav, thiab kev kho kom zoo, lub hauv paus granite tuaj yeem rov qab tau, kom ntseeg tau tias cov khoom siv semiconductor ua haujlwm tau zoo tshaj plaws.
