Hauv cov lag luam xws li semiconductors thiab precision electronics, uas muaj cov kev cai nruj heev rau qhov chaw tsim khoom, qhov huv ntawm lub chaw ua haujlwm tsis muaj plua plav cuam tshuam ncaj qha rau qhov txiaj ntsig ntawm cov khoom tsim tawm. Qhov teeb meem kev ua qias tuaj los ntawm kev xeb ntawm cov hlau cam khwb cia ib txwm yog qhov teeb meem nyuaj rau cov tuam txhab. Txawm li cas los xij, ZHHIMG cov kev daws teeb meem granite tau dhau daim ntawv pov thawj nrog nws cov kev ua tau zoo tshaj plaws, coj kev tawg tshiab rau kev lag luam.
Txawm hais tias cov hlau cam khwb cia siv dav hauv kev lag luam, lawv qhov kev tiv thaiv corrosion tsis zoo raug nthuav tawm tag nrho hauv ib puag ncig ntawm cov chaw ua haujlwm tsis muaj plua plav. Hlau cam khwb cia feem ntau yog tsim los ntawm hlau thiab carbon, thiab nws yooj yim rau cov tshuaj tiv thaiv oxidation nrog oxygen thiab dej noo hauv huab cua, tsim xeb. Hauv chaw ua haujlwm tsis muaj plua plav, txawm tias qhov xeb me me tuaj yeem tsim cov ntaub ntawv hlau. Thaum cov khoom me me no nkag mus rau hauv cov khoom siv precision lossis lo rau ntawm qhov chaw ntawm cov khoom, lawv tuaj yeem ua rau muaj kev cuam tshuam loj xws li luv luv circuits hauv semiconductor chips thiab kev ua qias tuaj ntawm cov khoom siv optical precision, ua rau muaj qhov tsis zoo ntawm cov khoom. Raws li cov ntaub ntawv kev lag luam, cov teeb meem tsis zoo ntawm cov khoom tshwm sim los ntawm kev ua qias tuaj ntawm cov hlau cam khwb cia suav txog 15% txog 20% ntawm kev ua tsis tiav hauv cov chaw ua haujlwm tsis muaj plua plav.
Cov tshuaj granite ZHHIMG tau daws qhov teeb meem ntawm kev ua qias tuaj ntawm cov hlau cam khwb cia. Granite feem ntau yog ua los ntawm cov zaub mov xws li quartz thiab feldspar. Nws muaj cov khoom siv tshuaj lom neeg ruaj khov heev, nrog rau pH kam rau siab ntawm 1 txog 14. Nws tsis tshua muaj kev cuam tshuam nrog cov tshuaj reagents acidic lossis alkaline thiab tsis raug oxidation nrog oxygen lossis noo noo hauv huab cua. Yog li ntawd, tsis muaj teeb meem ntawm xeb. Lub caij no, nws cov qauv ntom (porosity < 0.1%) ua rau nws qhov chaw du thiab tiaj tus, thiab nws tsis yooj yim rau adsorb plua plav thiab cov kuab paug. Txawm tias thaum siv ntev hauv qhov chaw ua haujlwm tsis muaj plua plav nrog cov kev xav tau huv si, nws tseem tuaj yeem tswj tau lub xeev huv, zoo zam cov teebmeem tsis zoo rau cov khoom los ntawm kev ua qias tuaj ntawm cov hauv paus.
Qhov tseem ceeb tshaj plaws yog tias ZHHIMG granite cov tshuaj tau dhau daim ntawv pov thawj ISO 14644-1 Class 5 chav huv chav. Daim ntawv pov thawj no muaj cov qauv nruj rau kev sib sau ua ke ntawm cov khoom me me hauv huab cua. Thaum peb lub hlis sib law liag ntawm kev sim ua tib zoo, lub hauv paus granite ZHHIMG ib txwm tswj hwm qhov tso tawm cov khoom me me qis heev, kom ntseeg tau tias nws yuav tsis ua rau muaj kuab paug rau qhov chaw ua haujlwm tsis muaj plua plav. Tsis tas li ntawd, lub platform granite kuj muaj cov coefficient qis heev ntawm kev nthuav dav thermal thiab kev tiv thaiv kev co zoo heev. Thaum ua kom huv ntawm lub chaw ua haujlwm tsis muaj plua plav, nws tuaj yeem muab kev txhawb nqa ruaj khov rau cov khoom siv precision, txhim kho kev ua haujlwm raug thiab kev ntseeg siab ntawm cov khoom siv.
Tom qab ib lub tuam txhab tsim khoom semiconductor uas paub zoo tau siv ZHHIMG granite solution los hloov cov hlau cam khwb cia, qhov tsis zoo ntawm nws cov khoom uas tshwm sim los ntawm kev ua qias tuaj tau poob qis heev los ntawm 8% mus rau 1.5%, kev ua haujlwm zoo dua 25%, thiab tus nqi txhua xyoo uas tau txuag tau vim yog kev pov tseg cov khoom tshaj 10 lab yuan. Qhov kev ua tiav zoo kawg no ua pov thawj tag nrho qhov txiaj ntsig zoo ntawm ZHHIMG granite solution hauv kev daws teeb meem kev ua qias tuaj hauv cov chaw ua haujlwm tsis muaj plua plav.
Nrog kev txhim kho tas mus li ntawm cov khoom ua tau zoo thiab cov kev xav tau zoo hauv ntau yam lag luam, qhov tseem ceeb ntawm cov chaw ua haujlwm tsis muaj plua plav tau dhau los ua qhov tseem ceeb. ZHHIMG granite cov kev daws teeb meem, nrog rau lawv cov yam ntxwv tsis xeb, huv si thiab ruaj khov, nrog rau kev txhawb nqa daim ntawv pov thawj, muab cov kev xaiv hauv paus txhim khu kev qha rau cov tuam txhab, pab kev lag luam txav mus rau qhov tseeb dua thiab kev tsim khoom zoo.
