Hauv txhua qhov kev daws teeb meem nws yuav tsum suav nrog cov khoom pabcuam, uas lub zog ua tiav thiab txhua yam khoom tsim nyog ncaj qha. Txhawm rau ua kom muaj txiaj ntsig zoo, koj yuav tsum siv ntau yam khoom siv-cement, dej thiab cov muab tshuaj zoo. Feem ntau ntawm cov xwm txheej, pob zeb tawg (hauv txoj hauv kev yooj yim, pob zeb tawg) yog siv los ua cov muab cov pob zeb ua, uas muaj kev ua tau zoo tshaj plaws uas pom tau zoo rau kev tsim kho. Txhawm rau ua kom muaj txiaj ntsig zoo, koj yuav tsum paub txhua yam khoom tseem ceeb ntawm cov pob zeb tawg, nrog rau nws ntau yam uas tuaj yeem siv tau.

Thawj qhov yuav tsum tau muaj

Cov kev ntsuas ntawm kev npaj sib tov ncaj qha nyob ntawm qhov xav tau yooj yim rau cov pob zeb tawg

1. Qhov nruab nrab tus nqi ntawm cov noob qoob loo pob zeb tawg yuav tsum sib npaug li 1, 4-3 grams rau 1 cm3.
2. Lub zog ntawm lub pob zeb qub thaum nyem, nws tau teeb tsa los ntawm qhov kawg tiv thaiv thaum lub sij hawm clamping thiab sib tsoo ntawm cov khoom tsim.
3. Flakiness . Qhov no yog qhov ntsuas uas qhia txog lub dav hlau ntawm pob zeb. Hauv kev tsim kho, cov phaj zoo li cov ntaub ntawv uas tsis muaj qhov ua tau zoo tau xyaum. Raws li qhov no, muaj ob peb hom pob zeb. Cov duab puab yog qhov zoo tshaj plaws, txij li nws ua tiav qhov kev cog lus zoo.
4. Kev faib ua feem (qhov loj me) ntawm cov pob zeb tawg rau pob zeb ua ke . Qhov ntsuas no teev qhov ntev ntawm cov khoom siv.
5. Frost tsis kam . Cov cuab yeej no yuav qhia hauv qhov ntsuas kub li cas txwv cov pob zeb tawg tuaj yeem siv tau. Tsab ntawv F yog siv rau kev cim, nrog rau tus lej qhia txog cov voj voog uas pob zeb tawg tuaj yeem tiv taus thaum khov thiab ua kom sov. Cov pob zeb tsoo nrog lub cim F300 tau txais txiaj ntsig zoo tshaj plaws. Qhov ntsuas no, tshwj xeeb, yuav tsum tau ua raws li cov xwm txheej ntawm kev tsim kho hauv tsev, qhov twg qhov kub ntawm huab cua nyob rau lub caij ntuj sov thiab lub caij ntuj no sib txawv ntau.
6. Xov tooj cua . Qhov ntsuas no qhia txog keeb kwm yav dhau los ntawm cov khoom siv hluav taws xob. Thaum qib 1 tau qhia rau ntawm pob, tom qab ntawv nws tuaj yeem siv tau hauv ntau txoj haujlwm. Hoob 2 yog siv rau kev paving.

Raws li tau hais dhau los, qhov feem cuam tshuam rau qhov ua tau zoo ntawm pob zeb tsis tsawg dua li hom pob zeb tawg. Nws qhov kev xaiv kuj yog nyob ntawm qhov kev thov ua haujlwm. Rau cov qhob cib, pob zeb tawg ntawm feem 5-70 millimeters . Qhov sib txawv zoo dua yog tsim los ntawm pab pawg ntawm 5-10 mm, 10-20 mm, 20-40 mm thiab 40-70 mm. Rau kev ua vaj tsev, nws yog qhov zoo dua los siv cov feem me me ntawm cov pob zeb thiab cov pob zeb sib tsoo, txij li qhov no cov muab tub lim tau siv yuav tau txais txiaj ntsig nrog qhov tshwj xeeb ntom ntom ntom ntom thiab siv lub zog me me rau ntawm cov cement tov, uas lav tau qhov tsim nyog ntawm kev txav mus los ntawm cov pob zeb sib xyaw.

Muaj cov qauv raws li qhov muab tub lim ntawm qhov loj me yuav tsum sib npaug los ntawm 1 txog 20% los ntawm qhov hnyav, thiab txo qhov loj me - tsis pub ntau tshaj 20% ntawm qhov sib xyaw.

Raws li SNiP 3.03.01-87, cov qhob tov yuav tsum muaj cov pob zeb tawg hauv nws cov qauv yam tsawg 2 feem nrog qhov txwv tus nqi ntawm cov khoom mus txog 40 mm thiab tsawg kawg 3 feem, thaum cov khoom loj tshaj yog 40-70 mm. Qhov loj tshaj plaws ntawm cov pob zeb tawg yuav tsum nyob hauv tsawg dua li ib feem peb ntawm qhov me tshaj plaws nyob nruab nrab ntawm cov khoom txhawb nqa ntev . Sib npaug, nws yuav tsum tsis pub ntau tshaj 1/3 ntawm qhov me me ntawm qee qhov kev tsim vaj tsev, piv txwv li, nws daim kab xev dav.

Cov kev pab cuam lub neej thiab kev ntseeg tau ntawm cov txheej txheem ua vaj tsev feem ntau tsis yog tsuas yog nyob ntawm qhov uas cov khoom siv tau zoo siv, tab sis kuj yuav ua li cas qhov sib xyaw ua kom raug

Txhawm rau kom tau txais cov pob zeb zoo, txhua cov ntsiab lus ntawm nws kev tsim khoom yuav tsum raug coj mus rau hauv tus account.

Yam pob zeb tawg yuav tsum tau ua rau ntau hom pob zeb sib txawv?

Ntau hom kev ua vaj tsev koom nrog kev siv ntau hom sib tsoo pob zeb.

M-100 qhob

Nws tsis muaj lub zog siab heev, nws tsis yog npaj rau cov txheej txheem tseem ceeb. Nws tau siv rau kev nchuav hauv av hauv qab daus, rau kev tsim lub hauv paus rau npog txoj kev, txoj kev taug kev, lub hauv paus. Txhawm rau npaj cov khoom sib xyaw, qib thib ob lossis limestone tsoo pob zeb nrog qhov loj ntawm 5-20 millimeters tuaj yeem siv tau.

Qhob M-150

Koom nrog kev ua vaj tsev nrog qhov nruab nrab lub zog muaj nuj nqis. Nws tau xyaum ua hauv kev tsim kho tus kheej rau qee qhov haujlwm me, suav nrog kev npaj ntawm lub hauv paus ntawm cov chaw thiab txoj hauv kev, kev tsim cov nplais, kev txhawb nqa thiab cov ncej, kev tsim kho ntawm cov hauv paus uas tsis muaj load.

Yuav muaj dab tsi tshwm sim yog tias koj xaiv qhov tsis raug?

Kev xaiv tsis raug cai qhov loj me ntawm cov khoom siv hauv tsev no tuaj yeem ua rau tsim cov khoom lag luam uas muaj cov khoom lag luam zoo.

Nws raug txwv tsis pub siv pob zeb tawg nrog qhov sib luag ib yam, vim qhov no tuaj yeem tsim qhov chaw khoob hauv cov pob zeb, uas txo nws txoj kev ruaj ntseg thiab zoo

Thaum ntxiv cov pob zeb, koj yuav tsum ua raws li cov feem. Yog tias muaj ntau dhau ntawm nws, nws tsis ua kom nruj rau cov cement, thiab cov qauv tau nrawm nroos nyob rau hauv qhov kev nqis tes ua. Qhov tsis txaus ua rau poob qis thiab txo qis hauv lub zog ntawm cov pob zeb.

Qhov ntim pom zoo yog 80% ntawm tag nrho cov ntim ntawm qhov sib xyaw.

Txhawm rau xyuas kom zoo ntawm cov khoom siv hauv tsev, ib feem ntawm cov pob zeb tawg rau pob zeb yuav tsum ua raws li cov kev cai ntawm GOST . Ib qho ntxiv, lwm qhov ntsuas ntawm qee yam khoom siv ntuj tsim tau muab - lawv hloov pauv raws li qhov chaw rho tawm. Cov chaw tsim khoom teeb tsa qhov ntsuas rau txhua pawg ntawm cov pob zeb tawg, thiab cov neeg siv khoom yuav tsum sib piv thiab xaiv cov yam ntxwv raws li cov haujlwm.

Nws tsis tuaj yeem muab cov lus teb rau lo lus nug ntawm qhov loj npaum li cas ntawm cov pob zeb tawg yog qhov zoo tshaj plaws rau kev sib xyaw.

Hauv txhua qhov tshwj xeeb, qhov kev xaiv nyob ntawm seb hom khoom siv twg uas koj xav tau kom tau txais.
