Cov teebmeem ntawm qhov sib txawv ntawm qhov kub thiab txias ntawm pob zeb feem ntau tshwm sim hauv cov hauv qab no:
1. Thermal expansion thiab contraction nyhuv:
- Pob zeb, raws li cov khoom ntxeem tau, yuav nthuav dav thiab cog lus thaum kub hloov pauv. Thaum lub pob zeb yog rhuab, lub ntim yuav nthuav; thaum nws txias, lub ntim yuav shrink. Qhov kev hloov ntim no yuav ua rau muaj kev ntxhov siab hauv lub pob zeb. Yog tias qhov kev ntxhov siab dhau qhov kev ua siab ntev ntawm lub pob zeb, nws yuav ua rau lub pob zeb tawg.
2. Sab hauv siab los ntawm dej evaporation:
- Cov dej hauv pob zeb yuav evaporate ntawm qhov kub thiab txias, ua rau lub siab sab hauv siab, yog li ua rau lub pob zeb tawg, tshwj xeeb tshaj yog thaum muaj dej nyob rau saum npoo los yog hauv lub pob zeb.
3. Kev cuam tshuam ntawm cov ntxhia muaj pes tsawg leeg:
- Cov ntxhia muaj pes tsawg leeg ntawm pob zeb yog rhiab rau qhov kub thiab txias mus rau qhov sib txawv degrees. Qee lub pob zeb yuav dhau mus rau theem kev hloov pauv lossis tshuaj lom neeg tom qab ua kom sov, ua rau cov pob zeb hloov pauv, ua rau tawg thiab huab cua.
4. Kev hloov ntawm lub zog thiab deformation yam ntxwv:
- Nyob rau hauv qhov kub thiab txias, lub zog thiab deformation yam ntxwv ntawm lub pob zeb yuav hloov. Piv txwv li, txhua yam khoom ntawm marble tsis hloov ntau ntawm chav tsev kub mus rau qhov kub ntawm 200 degree; Tab sis nyob nruab nrab ntawm 400 degree thiab 800 degree, nws lub siab tshaj plaws lub zog, elastic modulus thiab deformation modulus txo nrog nce kub, thaum lub ncov strain nce.
5. Kev hloov pauv ntawm qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom:
- Tom qab kev kho siab kub, qhov ntom ntom thiab pore cov khoom ntawm cov pob zeb ntawm cov liathhold sib txawv yuav hloov. Piv txwv li, qhov loj ntawm kev hloov pauv hauv qhov pore ntawm cov xuab zeb thiab shale tom qab kev kho kub kub yuav txawv nyob ntawm seb hom pob zeb. Shale muaj qhov chaw pore ntau dua vim yog kev sib xyaw ntawm cov organic teeb meem, ua rau muaj kev hloov pauv ntau dua hauv nws qhov pore.
6. Kev hloov pauv ntawm cov khoom acoustic thiab dynamic elastic tsis:
- Raws li qhov kub thiab txias nce, lub attenuation coefficient ntawm pob zeb tseem nce ntxiv, thiab lwm yam acoustic tsis txuas ntxiv mus. Nyob rau tib lub sij hawm, tag nrho cov dynamic elastic tsis tsuas yog Poisson tus piv qhia ib tug downward trend, tshwj xeeb tshaj yog rau shale uas yog ntau heev puas los ntawm tshav kub.
7. Qhov txawv ntawm refractoriness:
- Cov pob zeb sib txawv muaj qhov sib txawv refractoriness, thiab qee lub pob zeb yuav raug tshuaj lom neeg decomposition nyob rau hauv qhov kub thiab txias. Piv txwv li, gypsum decomposes ntawm qhov kub siab tshaj 107 degree, limestone thiab marble decompose ntawm qhov kub siab tshaj 910 degree, thiab granite tawg ntawm 600 degree vim cua sov tsis sib xws ntawm nws cov minerals.
Hauv cov ntsiab lus, qhov kub thiab txias muaj ntau yam cuam tshuam rau pob zeb, suav nrog kev hloov pauv ntawm lub cev, txo cov khoom siv dag zog, thiab kev puas tsuaj ntawm cov qauv. Cov kev hloov no tseem ceeb heev rau kev tiv thaiv thiab siv pob zeb.
