Hauv kev tsim kho kev lag luam, cov khoom siv xws li cov xuab zeb ua vaj tsev feem ntau siv. Nws qhov tshwj xeeb nyob hauv nws qhov kev tiv thaiv siab rau ntau hom kev cuam tshuam. Qhov ntau ntawm nws daim ntawv thov yog loj heev - nws yog paving slabs, thiab sab pob zeb, thiab pawg, thiab cov yeeb nkab kav dej. Kab lus no yuav tham txog yuav ua li cas dilute qhov sib xyaw no muaj txiaj ntsig zoo hauv kev tsim kho.
Kev faib ua feem ntawm cov xuab zeb
Txhawm rau txuag sijhawm, ntxiv rau kom tau txais kev daws teeb meem zoo dua, koj tuaj yeem yuav cov khoom sib xyaw ua kom qhuav hauv khw. Qhov sib piv ntawm cov xuab zeb thiab cov cement hauv lawv yog kwv yees tib yam: 1/3 mus rau cov cement, thiab 2/3 mus rau cov xuab zeb . Yog tias koj ua koj tus kheej, tom qab ntawd koj yuav tsum tsom mus rau qhov kev faib ua feem no.
Hmoov tsis zoo, feem ntau cov tuam txhab tsis tau muag cov khoom sib xyaw ua ke tau ntev. Ntxiv nrog rau cov khoom siv yooj yim, ntau yam tshuaj tsis huv tau pib ntxiv rau nws.
Ntau qhov ntsuas ntawm cov khoom kawg yog nyob ntawm lawv qhov ntau thiab qhov zoo, uas yog tiv taus qhov hloov pauv kub, yas, lub zog.
Yuav ua li cas dilute nrog dej?
Yog tias qhov sib xyaw qhuav tuaj yeem yuav tau npaj ua, tom qab txhua qhov xwm txheej koj yuav tsum tau ntxiv dej rau nws cov khoom sib xyaw koj tus kheej. Nyob ntawm qhov sib piv ntawm cov dej mus rau qhov seem ntawm qhov loj, cov kev daws teeb meem no tau muab faib ua 3 hom.
- Bold - muaj dej tsawg dhau hauv qhov sib xyaw . Qhov kev faib ua feem yog qhov tsis zoo, thiab yog tias muaj ntau dhau ntawm cov kua, cov tshuaj yuav tawg tom qab ua kom khov vim nws tsis yooj ywm thiab yas.
- Yooj yim - muaj dej ntau dhau hauv qhov sib xyaw . Nws qhov ntau dhau yuav ua rau qhov tseeb tias qhov sib xyaw tsis ua rau tawv nqaij txhua. Lwm qhov xwm txheej yog tias cov dej noo ntau dhau yuav dhau los ntawm kev daws teeb meem, thiab nws yuav ntsws ntau dua li tau npaj tseg.
- Ib txwm yog kev daws teeb meem nrog cov dej txaus . Qhov kev faib ua feem yuav tso cai rau cov xuab zeb ua kom tsis tsuas yog muaj zog, tab sis kuj yog yas, uas yuav txuag nws los ntawm kev tawg. Xws li kev sib xyaw yuav pom zoo tsis tsuas yog hais txog nws qhov zoo, tab sis kuj hais txog tus nqi.
Txhawm rau txhawm rau txhawm rau ua cov xuab zeb, koj yuav tsum ua raws li cov lus qhia hauv qab no:
- ib feem ntawm cov dej tau nchuav rau hauv lub ntim hauv qab cov khoom ua thawj kauj ruam;
- tom qab ntawd, yog tias muaj cov khoom sib xyaw ua ke, koj yuav tsum nchuav tag nrho cov dej sib tov qhuav thiab maj mam ntxiv cov dej ntxiv;
- yog tias tsis muaj cov cuab yeej siv, ntxiv me ntsis qhuav sib tov thiab maj mam ua.
Lwm qhov kev xaiv yog thawj zaug ntxiv tag nrho cov xuab zeb qhuav rau hauv lub khob, thiab tom qab ntawd ua kom lub qhov taub zoo li ntawm nws hauv nruab nrab. Dej yuav tsum maj mam nchuav rau hauv nws thiab sib xyaw. Txoj kev funnel yog qhov yooj yim dua thiab, qhov tseem ceeb tshaj plaws, muaj txiaj ntsig ntau dua li tso dej hla tag nrho thaj chaw ntawm qhov sib xyaw. Ua tsaug rau qhov no, nws muaj peev xwm sib tov cov tshuaj nrog dej maj mam kom pom tseeb ntawm qhov chaw nws yog lub sijhawm yuav tsum tau nres.
Feem ntau, tsis hais txog hom xuab zeb li cas, dej tau ntxiv rau hauv qhov sib xyaw hauv qab no: ib lub hnab 40 kg xav tau 6-7 liv dej.
Rau cov xuab zeb hom xws li M100 thiab M250, uas tau siv los ua cov khoom sib txuas , dej tuaj yeem ntxiv me ntsis ntxiv lossis tsawg dua ntawm koj qhov kev txiav txim siab. Tab sis rau lub hom phiaj tseem ceeb dua, piv txwv li, rau kev ua paving slabs lossis nchuav lub hauv paus, nws yog qhov zoo dua los ua raws cov qauv nruj - hauv qhov no, lub zog siab tshaj plaws thiab ua kom ntev ntawm cov pob zeb yuav raug lees paub.
Yuav ua li cas thiab ntau npaum li cas ntxiv cov pob zeb tawg?
Tom qab tsim cov xuab zeb sib xyaw ua ke, koj tuaj yeem npaj mus rau theem tom ntej - ntxiv ib qho ntxiv ntawm cov khoom sib xyaw - pob zeb tawg. Nws xav tau txhawm rau txhawm rau ua kom nruj ntawm cov khoom. Muaj 3 hom tseem ceeb ntawm cov pob zeb tawg, uas yog:
- limestone - pob zeb mos, tab sis khov -tiv taus;
- pob zeb yog hom nrov tshaj plaws, siv hauv kev tsim kho feem ntau;
- granite yog kim dua, tab sis pob zeb muaj zog tshaj, xav tau los tsim cov pob zeb muaj zog tshaj plaws.
Txhawm rau txiav txim siab ntau npaum li cas ntxiv cov pob zeb tawg, nws yog qhov zoo dua los xaiv qhov 2: 1 piv, uas yog, kwv yees li ib nrab ntawm qhov hnyav ntawm cov xuab zeb qhuav . Txawm li cas los xij, qhov ntsuas no yuav txawv nyob ntawm lub hom phiaj ntawm kev sib xyaw ua kom tiav. Yog li, rau cov haujlwm yooj yim, xws li gluing, koj tsis tas yuav ntxiv pob zeb tsoo txhua. Ntawm qhov tod tes, thaum ua cov pob zeb ua los ntawm cov xuab zeb ua lub hauv paus rau lub tsev, nws zoo dua yog siv cov granite thiab ntxiv nws hauv qhov loj dua - 2, 3-2, 5 txog 1.
Thaum cov dej tau ntxiv thiab sib xyaw kom zoo, cov pob zeb tawg tuaj yeem muab ntxiv rau cov tshuaj . Nws yog ib qho tsim nyog yuav tau ntxiv pob zeb rau hauv cov xuab zeb sib xyaw ua ke thiab maj mam ua. Qhov no yog lub ntsiab lus tseem ceeb heev: yog tias lub pob zeb tawg tsis sib luag nyob hauv qhov kev daws teeb meem, thaum kawg qhov no yuav ua rau kev faib khoom tsis zoo ntawm cov yam ntxwv ntawm cov pob zeb nws tus kheej.
Kev npaj cov av nplaum nthuav dav
Cov av nplaum nthuav dav yog cov khoom siv tau lub teeb heev uas raug rho tawm av nplaum tshwj xeeb hauv daim ntawv. Cov khoom ntawm cov av nplaum nthuav dav kuj tseem nyob ntawm nws cov khoom - nws kuj muaj qhov hnyav tsawg. Lwm qhov zoo ntawm qhov kev daws teeb meem no suav nrog:
- tus nqi qis - qhov tseeb, rau kev tsim cov av nplaum nthuav dav tsis xav tau tus nqi ntau, vim qhov kev daws teeb meem no tau nrov heev ntawm cov neeg uas koom nrog kev tsim kho tas li;
- thermal conductivity tsis zoo - qhov no tso cai rau koj siv cov khoom sib xyaw no hauv cov chaw uas nws yuav tsum tau ua kom sov thiab tsis txhob txias txias.
Kuj tseem muaj qhov tsis zoo, piv txwv li, nthuav av nplaum ua vaj tsev muaj qhov siab nqus dej noo. Vim li no, muaj qee qhov kev txwv nws siv hauv qhov chaw uas muaj dej ntau tuaj yeem nkag tau rau nws.
Nthuav av nplaum ua los ntawm cov xuab zeb los yog los ntawm cov pob zeb zoo tib yam yuav luag zoo ib yam. Qhov sib txawv ntawm lawv tsuas yog nyob hauv hom muab tub lim: nthuav av nplaum tsis txhob siv pob zeb tsoo. Cov tshuaj no yog sib xyaw zoo li cov xuab zeb ua vaj. Cov Cheebtsam yuav tsum tau ntxiv rau hauv qhov sib piv hauv qab no: C1: P3: K4: B1, 5 lossis Ts1: P4: K5: B2, qhov twg, ntsig txog, C yog xis mas, P yog xuab zeb, K nthuav av nplaum, V yog dej.
Qhov kev txiav txim ntxiv yog tib yam
- Rau pob zeb ua tov . Ib feem ntawm cov dej tau ntxiv, tom qab ntawd sib tov qhuav. Tom qab ntawd cov dej tas yog nchuav tawm thiab nthuav av nplaum ntxiv.
- Thaum tsis muaj pob zeb tov khoom . Koj yuav tsum xub nchuav cov dej sib tov qhuav, ntxiv dej rau nws thiab maj mam muab sib xyaw rau hauv cov homogeneous loj. Tom qab ntawd, muab cov kua nplaum tso rau hauv daim ntawv ntawm cov av nplaum nthuav.
Nws yog ib qho tseem ceeb kom nco ntsoov tias cov av nplaum nthuav dav tau nkag siab dej. Yog tias muaj ntau dhau ntawm nws hauv qhov sib xyaw, tom qab ntawd nthuav av nplaum yuav yooj yim ntab vim nws qhov ntom ntom.
Cov xuab zeb ua vaj tsev yog cov khoom nrov heev hauv kev tsim ntau yam haujlwm tsim kho.
Nyob rau tib lub sijhawm, txhua tus tuaj yeem ua nws - tsuas yog ntxiv txhua cov khoom xyaw hauv qhov raug thiab hauv qhov raug.
