Dab tsi yog lub hauv paus ntsiab lus ntawm kev ua vaj tse impermeability?

I. Kev Taw Qhia

Concrete impermeability technology, raws li cov txheej txheem tseem ceeb hauv kev tsim kho engineering, yog lub luag haujlwm tiv thaiv cov dej nkag mus rau hauv cov pob zeb ua vaj tse thiab ua kom lawv muaj kev nyab xeeb. Kab lus no yuav piav qhia txog qhov tsis meej ntawm cov cuab yeej ua tsis tau zoo, suav nrog nws cov txheej txheem, cov qauv tsim, thiab cov txheej txheem tsim kho kom nthuav dav tag nrho ntawm cov thev naus laus zis no.

II. Mechanism ntawm Concrete Impermeability

Lub impermeability ntawm qhob stems los ntawm kev sib cuam tshuam ntawm nws cov pore qauv thiab cov yam ntxwv ntawm permeating nruab nrab. Lub pore qauv ntawm cov pob zeb txiav txim siab txoj kev sib kis thiab kev sib kis rau cov dej noo, thaum cov khoom ntawm permeating nruab nrab cuam tshuam rau hom thiab ceev ntawm noo noo txav hauv qhov pores.

Qhob Pore Structure

Lub pore qauv ntawm pob zeb muaj cov yam ntxwv tseem ceeb xws li pore loj, porosity, thiab pore tis. Cov pores no tuaj yeem sib xyaw ua ke rau hauv capillary pores, mesopores, thiab macropores. Capillary pores, nrog diameters tsawg dua 50nm, siv capillary suction rau stubbornly thaiv noo noo intrusion; mesopores tiv thaiv ntev-ntev ya raws infiltration los ntawm diffusion thiab convection; macropores coj cov dej ntws.

Cov yam ntxwv ntawm Permeating Medium

Cov yam ntxwv ntawm qhov nruab nrab permeating, nrog rau osmotic siab, viscosity, thiab nto nro, ncaj qha cuam tshuam rau kev thauj tus cwj pwm ntawm ya raws hauv pob zeb. Osmotic siab tsav cov dej noo mus rau hauv cov pob zeb, viscosity txiav txim siab qhov yooj yim ntawm cov dej ntws hauv qhov pores, thiab qhov nro saum npoo ua ib zaj duab xis ntawm cov dej noo ntawm cov pob zeb. Cov rog no cuam tshuam los tsim cov kev txav mus los ntawm cov dej noo hauv cov pob zeb.

Hom Moisture Moisture nyob rau hauv pob zeb

Moisture nyob rau hauv qhob txav nyob rau hauv ntau txoj kev, feem ntau los ntawm diffusion, convection, thiab molecular adsorption. Diffusion tso cai rau ya raws maj mam nce los ntawm kev sib tsoo molecular thiab diffusion txav hauv qhov pores; convection enables sai ya raws nyob rau hauv lub pores los ntawm cov kua inertia thiab viscous rog; molecular adsorption tsim ib txheej adsorbed rau ntawm qhov chaw pore, cuam tshuam rau kev thauj mus los ntawm kev ya raws los ntawm kev sib cuam tshuam thiab kev cuam tshuam cov rog.

III. Lub hauv paus ntsiab lus ntawm Kev Tsim Kho Kev Tsim Kho Kom Zoo

Concrete impermeability tsim lub hom phiaj los xyuas kom meej tias cov pob zeb ua kom zoo heev impermeability thaum ntsib ib puag ncig nyuaj. Cov hauv qab no yog cov hauv paus ntsiab lus tseem ceeb uas yuav tsum tau ua raws li kev tsim qauv impermeability:

Kev txiav txim siab ntawm cov qauv tsim

Kev txiav txim siab tus qauv tsim tsis yog qhov pib rau kev tsim qauv impermeability. Qhov no suav nrog qib zog ntawm pob zeb, qib impermeability, engineering ib puag ncig, thiab cov yam ntxwv ntawm qhov nruab nrab permeating. Kev xaiv ntawm cov kev txwv no yuav tsum ua tib zoo xav txog kev siv cov kev cai ntawm cov qauv pob zeb, ib puag ncig, thiab cov kev xav tau tiag tiag ntawm engineering los xyuas kom meej tias cov qauv tsim ua vaj tse muaj cov impermeability zoo heev.

Kev xaiv cov pob zeb sib xyaw kom haum

Qhov sib xyaw ua ke sib piv yog qhov tseem ceeb hauv kev txiav txim siab nws cov impermeability. Qhov sib xyaw kom haum ua kom ntseeg tau tias cov pob zeb muaj lub zog txaus thiab qhov ntom ntom zoo, txhim kho nws cov impermeability. Thaum xaiv qhov sib tov sib xyaw, yam xws li cov khoom siv, ib puag ncig engineering, thiab kev siv cov kev xav tau yuav tsum tau txiav txim siab tag nrho los xyuas kom meej tias cov pob zeb ua tau raws li qhov xav tau ntawm lub zog thaum tseem muaj cov impermeability zoo.

Optimization ntawm pob zeb Pore Structure

Lub pore qauv ntawm pob zeb cuam tshuam nws impermeability. Los ntawm kev ua kom qhov ntom ntom ntawm cov pob zeb, tswj qhov pore loj thiab porosity, thiab ntxiv qhov tsim nyog ntawm cov ntaub ntawv khi, lub pore qauv ntawm cov pob zeb tuaj yeem ua kom zoo, txo cov kev sib kis thiab kev sib kis rau cov dej noo hauv cov pob zeb, yog li txhim kho nws cov impermeability.

Txhim kho qhov ntom ntom ntawm pob zeb

Qhov ntom ntom ntawm cov pob zeb yog qhov tseem ceeb rau nws cov impermeability. Los ntawm kev ntxiv dag zog rau kev kho, siv cov densifiers saum npoo, thiab txhim kho txoj kev kho saum npoo, qhov ntom ntom ntawm cov pob zeb tuaj yeem txhim kho tau zoo, txo cov dej noo infiltration thiab yaig ntawm cov pob zeb, yog li txhim kho nws cov impermeability.

IV. Kev tsim kho cov txheej txheem rau pob zeb impermeability

Cov txheej txheem kev tsim kho impermeability yog cov tswv yim siv ntawm kev tsim impermeability, ua ib kauj ruam tseem ceeb los xyuas kom meej tias cov vaj tse pob zeb muaj impermeability zoo heev. Cov hauv qab no yog cov txheej txheem tseem ceeb rau kev tsim ua vaj tse impermeability:

Kev tsim kho vaj tse

Kev tsim kho pob zeb yog lub hauv paus ntawm tag nrho cov txheej txheem kev tsim kho impermeability. Thaum lub sij hawm tsim kho, qhov sib xyaw ua ke ntawm cov pob zeb yuav tsum tau ua raws li nruj me ntsis, thiab cov ntsiab lus tseem ceeb xws li dej-cement ratio thiab xuab zeb piv yuav tsum raug tswj xyuas kom meej tias cov pob zeb muaj zog thiab ntom ntom raws li cov qauv tsim.

Kev kho pob zeb ceev

Txhawm rau txhim kho qhov impermeability ntawm cov pob zeb, kev kho kom ceev yog ib kauj ruam tseem ceeb. Qhov no suav nrog kev siv cov densifiers saum npoo, ntxiv dag zog rau kev kho pob zeb, thiab ua cov kev kho saum npoo los txhim kho qhov ntom ntom ntawm cov pob zeb, tiv thaiv kev ya raws thiab yaig.

Waterproof Txheej Kev Tsim Kho

Kev tsim kho cov txheej txheem dej tsis zoo yog cov kauj ruam tseem ceeb hauv kev tsim ua vaj tse impermeability. Thaum lub sij hawm tsim kho, kev tsim qauv yuav tsum tau ua raws li nruj me ntsis kom ntseeg tau tias lub thickness, xaiv cov khoom siv, thiab kev tsim qauv ntawm cov txheej txheem dej tsis haum. Tsis tas li ntawd, kev saib xyuas yuav tsum tau them rau qhov zoo ntawm cov txheej txheem dej tsis zoo, kom ntseeg tau tias nws ua raws li cov pob zeb ua ke los tsim ib qho kev thaiv dej tsis zoo.

Kev soj ntsuam zoo ntawm cov txheej txheem dej tsis zoo

Txhawm rau kom ntseeg tau tias cov txheej txheem dej tsis zoo ntawm kev tsim kho tau raws li cov qauv tsim, kev tshuaj xyuas nruj yog tsim nyog. Kev tshuaj xyuas suav nrog ntau yam xws li thickness, ntom, impermeability, thiab durability ntawm txheej waterproof. Tsuas yog thaum txhua qhov ntsuas tau ua tau raws li cov qauv tuaj yeem ua kom cov txheej txheem dej tsis muaj dej kom paub tseeb tias tsim nyog, kom ntseeg tau tias qhov ua tau zoo impermeability ntawm cov qauv pob zeb.
