Raws li qhov loj ntawm nws cov khoom siv lead ua, nws tuaj yeem muab faib ua cov siv lead ua zoo, nruab nrab siv lead ua, coarse crystal, thiab porphyritic, thiab lwm yam. Nws cov xim thiab luster yog txiav txim siab los ntawm feldspar, mica thiab cov ntxhia tsaus, feem ntau grey, daj, tsaus liab. , lwm.

1. Granite kuj yog ib qho ntawm cov phaj. Thiab hauv peb lub neej niaj hnub, peb feem ntau siv granite, uas tsis yog qis dua lwm cov ntaub ntawv.
2. Ib hom kev tsim khoom ntawm granite flamed vuas, uas txiav cov ntshiab ntuj granite rau hauv slabs, grinds saum npoo ntawm cov slabs, muab tso rau ntawm lub txee ruaj tom qab thawj zaug sib tsoo, thiab tom qab ntawd nqa cov nplaim hluav taws kub hnyiab rau saum npoo tom qab. pib sib tsoo. Nws cov yam ntxwv nyob ntawm kev xaiv cov roj acetylene rau cov nplaim hluav taws
3. Cov phom tsuag txav sib npaug ntawm qhov chaw nrog kev txav ceev ntawm 120 ~ 250mm ib ob. Qhov kev ncua deb ntawm lub nozzle thiab qhov chaw yog 20 ~ 40mm thiab yog inclined rau ib leeg. Cov nplaim hluav taws kub yog 800 ~ 1000 degree. Ua ntej tua hluav taws, tshuaj tsuag dej rau ntawm cov slabs (kom tsis txhob hlawv cov slabs thaum tua hluav taws, thiab cov dej evaporates thiab absorbs tshav kub thaum nws rhuab).
3. Cov txheej txheem ntau lawm ntawm granite flamed vuas suav nrog kev tsim thiab kev siv tshuab ntawm granite. Txiav lub ntuj ntshiab granite rau hauv ib lub slab, zom cov nplais ntawm cov nplais los ntawm kev sib tsoo thawj zaug, thiab tom qab ntawd muab cov nplaim hluav taws tso rau saum npoo ntawm qhov sib tsoo thawj zaug, thiab tom qab ntawd poob saum npoo ntawm 0.5 ~ 1mm.
Cov ntaub ntawv raw ntawm granite tsim thiab ua tiav nyob rau hauv txoj kev no nthuav tawm cov xim qub ntawm lub pob zeb, uas yog antique, crude thiab ntawm chav kawm hnyav. Granite hluav taws board tuaj yeem siv rau hauv kev hla kev, txoj kev, sab hauv tsev pavement thiab phab ntsa.
