Hauv kev siv cov khoom siv ntsuas qhov tseeb, qhov tseeb thiab ruaj khov ntawm cov khoom siv muaj feem cuam tshuam ncaj qha rau qhov tseeb ntawm cov txiaj ntsig ntsuas, thiab kev xaiv cov ntaub ntawv los nqa thiab txhawb nqa cov cuab yeej ntsuas yog qhov tseem ceeb heev. Granite thiab marble, ua ob yam khoom siv pob zeb zoo, feem ntau raug txiav txim siab rau kev tsim cov khoom siv ntsuas qhov tseeb, tab sis qhov twg zoo dua? Cia peb khawb tob dua.
Kev sib piv ntawm kev ruaj khov
Kev ruaj khov yog lub hauv paus tseem ceeb ntawm cov khoom siv ntsuas qhov tseeb. Granite yog tsim nyob rau hauv lub ntiaj teb lub plhaub tob, tom qab kub thiab siab siab rau lub sijhawm ntev quenching, cov qauv sab hauv yog ntom thiab sib xws. Ntau lab xyoo ntawm kev laus ntuj ua rau nws cov kev ntxhov siab sab hauv tau raug tso tawm tag nrho, uas ua rau granite ruaj khov heev. Thaum cov yam ntxwv ib puag ncig xws li kub thiab av noo hloov pauv, granite deformation yog me me heev.
Qhov sib txawv, marble, txawm hais tias nws kuj tau tsim tom qab lub sijhawm ntev geological txheej txheem, tab sis nws cov qauv crystalline yog qhov ntxhib, thiab cov khoom muaj ntau cov zaub mov xws li calcium carbonate. Cov yam ntxwv no ua rau marble nthuav dav lossis cog lus yooj yim dua thaum ntsib kev hloov pauv ib puag ncig. Piv txwv li, nyob rau hauv ib puag ncig nrog kev hloov pauv kub loj, qhov kev hloov pauv loj ntawm marble yuav cuam tshuam rau qhov ntsuas qhov tseeb ntawm cov khoom siv ntsuas qhov tseeb, thaum granite tuaj yeem tswj tau qhov ruaj khov zoo dua thiab muab lub hauv paus txhim khu kev qha rau cov cuab yeej ntsuas.
Kev tawv thiab kev hnav tsis kam
Cov khoom siv ntsuas qhov tseeb thaum siv cov txheej txheem mus sij hawm ntev, nws yuav raug kev txom nyem los ntawm ntau yam kev sib txhuam thiab kev sib tsoo. Granite yog cov khoom tawv, thiab nws qhov nyuaj ntawm Mohs feem ntau yog li 6-7, uas tuaj yeem tiv taus kev hnav sab nraud thiab khawb. Thaum muab cov cuab yeej ntsuas thiab cov qauv tso rau hauv thiab txav mus los ntau zaus, qhov chaw granite tsis yooj yim tawm cov cim pom tseeb, yog li nws thiaj li tswj tau nws qhov tiaj tus thiab qhov tseeb ntev.
Qhov nyuaj ntawm marble yog qhov tsawg heev, thiab Mohs hardness feem ntau yog 3-5. Qhov no txhais tau tias nyob rau hauv tib lub sijhawm ntawm kev siv, qhov chaw marble yog qhov yooj yim rau khawb thiab hnav, thiab thaum qhov du ntawm qhov chaw puas lawm, nws yuav muaj qhov cuam tshuam tsis zoo rau qhov tseeb ntawm cov khoom siv ntsuas precision. Rau cov khoom siv ntsuas uas xav tau kev ua haujlwm ntev, kev ua haujlwm siab, qhov nyuaj siab thiab hnav tsis kam ntawm granite yog qhov kev xaiv zoo tshaj plaws.
Kev tshuaj xyuas kev tiv thaiv corrosion
Tej zaum yuav muaj ntau yam tshuaj lom neeg nyob rau hauv qhov chaw ntsuas, xws li kev ua kom cov kua qaub-raws li cov tshuaj reagents volatilization, uas ua rau muaj kev sib tw rau kev tiv thaiv corrosion ntawm cov khoom siv. Granite feem ntau yog tsim los ntawm quartz, feldspar thiab lwm yam minerals, cov khoom siv tshuaj lom neeg ruaj khov, nrog kev tiv thaiv acid zoo heev, tiv thaiv alkali. Hauv cov chaw tshuaj lom neeg nyuaj, granite tuaj yeem tswj nws tus kheej lub cev thiab tshuaj lom neeg ntev ntev kom ntseeg tau tias kev ua haujlwm ruaj khov ntawm cov khoom siv ntsuas qhov tseeb.
Vim yog cov tshuaj lom neeg ua haujlwm ntawm nws cov khoom tseem ceeb calcium carbonate, marble yooj yim rau cov tshuaj tiv thaiv thaum ntsib cov tshuaj acidic, ua rau xeb thiab puas tsuaj rau qhov chaw. Qhov xeb no tsis tsuas yog cuam tshuam rau qhov tsos ntawm marble, tab sis kuj ua rau nws cov qauv ruaj khov, thiab tom qab ntawd cuam tshuam rau qhov tseeb ntawm cov khoom siv ntsuas qhov tseeb. Yog li ntawd, nyob rau hauv qhov chaw ntsuas qhov twg muaj kev pheej hmoo ntawm kev xeb tshuaj lom neeg, qhov kev tiv thaiv corrosion ntawm granite ua rau nws yog cov khoom siv txhim khu kev qha dua.
Kev ruaj khov, kev tawv thiab kev hnav tsis kam thiab kev tiv thaiv corrosion thiab lwm yam, granite hauv ntau yam cim tseem ceeb tau qhia zoo dua li marble. Rau cov khoom siv ntsuas qhov tseeb uas xav tau qhov tseeb thiab kev ruaj khov siab, granite yog qhov kev xaiv zoo dua. Nws tuaj yeem muab lub hauv paus ruaj khov thiab txhim khu kev qha rau cov cuab yeej ntsuas, xyuas kom meej qhov tseeb thiab kev ntseeg siab ntawm cov txiaj ntsig ntsuas, thiab pab ua haujlwm ntsuas qhov tseeb hauv kev tshawb fawb, kev tsim khoom lag luam thiab lwm yam teb kom ua tiav zoo.
