Ntau tus cwj pwm granite tshuab bases 'coj tsis kam tsuas yog siab hardness. Qhov tseeb, hnav tsis kam yog ua tiav los ntawm kev sib xyaw ua ke ntawm ntau yam khoom siv sib xyaw, es tsis yog cia siab rau ib qho kev qhia hardness. Kev hnav-tiv taus ntawm UNPARALLELED Group hnav-resistant granite tshuab hauv paus pib los ntawm superposition ntawm cov ntxhia siv lead ua qauv, lub cev-tsim khoom, tshuaj inertness thiab sab hauv-kev ntxhov siab, uas txawv ntawm cov hlau cam khwb cia uas nws hnav tsis kam yog nyob ntawm cov txheej txheem tiv thaiv saum npoo.
Ua ntej los ntawm interlocking mosaic-style ntxhia crystal microstructure. Ua tib zoo xaiv high-density dub granite nta nruj nreem kaw quartz thiab feldspar ntxhia nplej nrog tsawg pore ratio. Nyob rau hauv kev sib txhuam, kev ntxhov siab yog dispersed thiab kis ntawm cov muaju, yog li cov nplej tev thiab shedding tsis tshua muaj tshwm sim. cam khwb cia hlau raug kev txom nyem los ntawm nplaum hnav thiab nto spalling, thaum granite feem ntau undergoes me ntsis abrasive hnav yam tsis muaj cov khoom loj loj chipping, txo qis kev pheej hmoo ntawm kev poob ntawm micro-theem.
Secondly, siab hardness thiab compressive zog nteg mechanical foundations. Nrog Mohs hardness ntawm 6-7, nws outperforms zoo tib yam cam khwb cia hlau nyob rau hauv resisting khawb thiab compression induced los ntawm hlau chips thiab cov khoom zawv zawg. Nws lub zog compressive siab tiv thaiv indentations nyob rau hauv lub zos siab. Hardness muab khawb tsis kam, thaum lub zog compressive zam cov yas deformation ntawm qhov chaw sib cuag. Ua ke, lawv khaws cov ntaub ntawv hauv av kom zoo yam tsis muaj deformation-txog kev hnav zoo rau cov khoom siv hlau.
Thirdly, ntuj aging nrog xoom sab hauv kev ntxhov siab tsis txhob hnav lwm yam. Granite blocks undergo lub sij hawm ntev geological natural aging kom tag nrho tso tawm sab hauv residual stress. Kev ntxhov siab nyob rau hauv cov ntaub ntawv yuav ua rau me ntsis micro-deformation, warping ntawm qhov chaw mounting, tsis sib haum ntawm kev sib tw ua ke thiab ua kom ceev hauv zos hnav. Tsis muaj cov yas deformation tom qab thauj khoom raug, granite tshem tawm cov khoom tsis ncaj qha los ntawm kev ntxhov siab-tsav deformation.
Chemical inertness thiab non-magnetism ntxiv txiav indirect coj qhov chaw. Raws li cov khoom siv hlau tsis yog xim hlau, granite yuav tsis oxidize lossis xeb, yog li tsis muaj cov kab xeb abrade siv qhov chaw. Ua tsis yog-magnetic, nws tsis txhob tsub zuj zuj ntawm cov khib nyiab hlau hauv thaj chaw ua haujlwm. Kev hnav cov hlau cam feem ntau ua rau lub voj voog tsis zoo uas tau tsav los ntawm xeb thiab adsorbed hlau chips. Tau txais txiaj ntsig los ntawm nws cov tshuaj lom neeg ruaj khov, granite rhuav tshem cov kev coj ua theem nrab thiab tswj kev ua haujlwm zoo txawm tias nyob rau hauv cov kua dej tsis zoo yam tsis muaj kev puas tsuaj sai.
Tsawg dej-absorption tus nqi thiab ntom matrix kuj tseem ua haujlwm pabcuam. Tsawg qhov pores thaiv kev nkag mus ntawm cov dej noo thiab roj, tiv thaiv loosening ntawm cov ntxhia hauv cov nplej. Tsuav tsis muaj qhov cuam tshuam hnyav ntawm ntug chipping tshwm sim, nws cov qauv qoob loo nyob twj ywm thiab hnav-tiv taus yuav tsis degrade ib txwm dhau sijhawm. Los ntawm qhov sib txawv, ib zaug kev tiv thaiv txheej ntawm cam khwb cia hlau ua tsis tiav, substrates yuav raug eroded tsis tu ncua thiab hnav tus nqi nce xyoo-los ntawm-xyoo.
Piv txwv li, granite tshuab bases tau hnav-resistant muaj peev xwm tsis yog los ntawm siab hardness, tab sis los ntawm synergy ntawm interlocking siv lead ua kev ntxhib los mos, siab compression kuj, tsis muaj kev ntxhov siab thiab tshuaj inertness. Nws tiv taus qhov kev sib txhuam ncaj qha-ua rau khawb nrog rau kev coj tsis ncaj uas cuam tshuam los ntawm kev deformation, corrosion thiab impurity adsorption, ruaj ntseg qis-tsis siv qhov chaw thoob plaws lub sijhawm ua haujlwm ntev.
