Ndi zosakaniza simenti chiyani?

Simenti - mmodzi wa zipangizo maziko ntchito malowa kuchokera kalelo. The zikuchokera simenti zikuphatikizapo angapo zinthu zochita kupanga zomwe anakumana ndi madzi kupanga njira otchedwa. Ndi mndandanda wa makhalidwe enieni thupi, pamene youma njira ikamauma.

Simenti amapangidwa m'njira zosiyanasiyana, koma ambiri a iwo ntchito ziwiri: youma ndi yonyowa. kupanga ake - mtengo ndithu ndi mphamvu-tima ndondomeko. Otchedwa sludge mu maonekedwe ake oyambirira yodzaza mu uvuni yapadera, ndipo kenako sintering pa chibanthu. Pa kupanga ndondomeko ng'anjo ndi mosalekeza zimayenda, kotero kuti chibanthu ndi uniformly losanganikirana. Zimenezi zimathandiza kuti osakaniza kwambiri homogeneous ndipo wogawana isungunuke.

The zikuchokera simenti m'gulu chitsulo okusayidi. Iwo ali amadza lalikulu kwambiri pa ubwino waukulu wa chifukwa osakaniza simenti. Polimbikitsa wapamwamba - ndi chitsulo okusayidi zili pafupifupi 10%. Pa chiŵerengero izi oxides ndi zotsatira zabwino kwambiri pa miyala mapangidwe. Komabe, muyeso zonse zofunika, kotero kuonjezera chiwerengero cha chitsulo okusayidi simenti ndi yafupika ndi akukhudzidwira ndi khalidwe lake.
The pazipita mlingo kololeka imatengedwa 25% ya chitsulo okusayidi. Monga mukudziwa, simenti amagwiritsidwanso ntchito yomanga kapena mapangidwe nyumba kutentha zosagwira ndi nyumba. Pankhaniyi, pamaso pa oxides chitsulo ndi zosayenela. Komanso kuchuluka kwa chitsulo kumakhudza mwachindunji pa mtundu simenti: chipepukeko ndi, chindichepere kuchuluka zina. Gray simenti, mosiyana, ali mu dongosolo zake zili chapamwamba oxides chitsulo.

Ngati zina disassemble mipweya simenti, ndi zotheka kuti azindikire ndi aluminiyamu. Kuchuluka wamkulu wa aluminiyamu ali zikuchokera simenti, akuupereka katundu kukaniza kutentha. Qualitatively, okhutira simenti wa thunthu ndi pafupifupi 60%.

Kuwonjezera oxides awa, zikuchokera simenti zikuphatikizapo oxides calcium, pakachitsulo, magnesium. opanga simenti zikukangalika kumenyana kotero kuti zinthu zawo mulibe munthu okusayidi chromium, chomwe ndi zitsulo udakali amabwera mu zochita zoipa mankhwala.

Malinga zikuchokera simenti, izo lagawidwa mitundu ndi osiyana thupi katundu: gipsoshlakovy, kudya reader, phulusa, aluminiyamu, gipsoglinozemisty ndi madzi.

The zikuchokera simenti kusintha makhalidwe ake kuwonjezera zina zosiyanasiyana yogwira mchere. Iwo yokumba kapena zachilengedwe chiyambi. Zina simenti akuupereka katundu osiyana: bwino workability ndi kuwonjezeka zolowa, kusintha scalability, kuchepetsa shrinkage, plasticity ndi kusintha kachulukidwe. Komanso Kuwonjezera zinthu zimenezi kumathandiza durability ndi mphamvu ya slurries simenti.

Zina simenti osati ntchito pofuna kupititsa patsogolo chuma yake yeniyeni thupi, komanso kusintha Mwachitsanzo, mtundu. Pakuti zolinga zimenezi, mukhoza kugwiritsa ntchito utoto zonse.
