Cov pob zeb granite beams yog ua los ntawm cov pob zeb zoo "Jinan Blue" los ntawm kev siv tshuab thiab kev ua tiav tes. Lawv muaj cov qauv zoo sib xws, ruaj khov zoo heev, muaj zog heev, thiab tawv heev, tswj tau qhov tseeb siab hauv qab cov khoom hnyav thiab ntawm qhov kub nruab nrab. Lawv kuj tiv taus xeb, tiv taus kua qaub thiab alkali, tiv taus hnav, muaj cov xim dub ci, cov qauv meej, thiab tsis muaj hlau nplaum thiab tsis yooj yim hloov pauv.
Cov khoom siv granite yooj yim kho thaum siv, cov khoom ruaj khov uas ua kom muaj kev hloov pauv mus sij hawm ntev, cov coefficient nthuav dav qis, kev ua haujlwm raug siab, thiab tsis xeb, tiv thaiv hlau nplaum, thiab rwb thaiv tsev. Lawv tsis yooj yim hloov pauv, tawv, thiab tiv taus kev hnav.
Cov khoom siv granite yog ua los ntawm cov khoom siv pob zeb zoo thiab ua haujlwm ua cov cuab yeej ntsuas. Lawv yog cov rooj ua haujlwm tseem ceeb rau kev cim, ntsuas, riveting, vuam, thiab cuab yeej. Lawv kuj tseem siv tau ua cov rooj sib tw kuaj tshuab rau ntau yam haujlwm tshuaj xyuas, ua cov dav hlau siv rau kev ntsuas qhov tseeb, thiab ua cov qauv ntsuas rau kev tshuaj xyuas cov cuab yeej siv tshuab los xyuas qhov tseeb lossis qhov sib txawv ntawm qhov chaw. Lawv yog qhov kev xaiv zoo heev rau kev lag luam tshuab thiab kuj nrov hauv cov chaw soj nstuam. Cov khoom siv granite xav tau kev saib xyuas zoo, ntev mus ntev thiab qib siab ntawm qhov chaw ua haujlwm. Qhov tseeb ntawm cov khoom nws tus kheej yog qhov tseem ceeb rau kev ua kom ntseeg tau qhov tseeb thiab zoo ntawm cov khoom tiav thaum lub sijhawm ua thiab sim.
Cov pob zeb granite muaj cov txiaj ntsig zoo li nram no:
1. Kev ntsuas raug siab, ruaj khov zoo heev, thiab tiv taus kev hloov pauv. Kev ntsuas raug tau lees paub ntawm qhov kub thiab txias hauv chav.
2. Tiv taus xeb, tiv taus kua qaub thiab alkali, tsis tas yuav tsum tau saib xyuas tshwj xeeb, thiab muaj kev tiv taus kev hnav zoo heev thiab lub neej ua haujlwm ntev.
3. Cov khawb thiab cov qhov ntawm qhov chaw ua haujlwm tsis cuam tshuam rau qhov tseeb ntawm kev ntsuas.
4. Kev ntsuas tuaj yeem ua tau zoo yam tsis muaj kev ncua lossis qeeb.
5. Cov khoom siv granite yog cov khoom siv uas tsis yooj yim puas, tsis yooj yim kub, thiab yooj yim rau kev saib xyuas. Lawv ruaj khov thiab muaj cov qauv zoo. Kev cuam tshuam tuaj yeem ua rau cov noob poob, tab sis qhov saum npoo tsis burr, uas tsis cuam tshuam rau qhov tseeb ntawm cov phaj ntsuas granite. Kev laus ntuj ntev ntev ua rau muaj cov qauv sib xws, cov coefficient nthuav dav tsawg kawg nkaus, thiab tsis muaj kev ntxhov siab sab hauv, tiv thaiv kev hloov pauv.
