Txhawm rau tsim kom muaj kev thaj yeeb nyab xeeb hauv cov tsev niaj hnub no, siv cov dej tsis muaj dej, uas tiv thaiv kom tsis txhob ya raws hauv lub tsev. Qhov nrov tshaj plaws yog cement waterproofing. Nws yog ib qho pheej yig dua rau cov khoom kim heev. Tsis tas li ntawd, nws qhov txiaj ntsig tsis txaus ntseeg yog tias txawm tias tus tsim tsis muaj kev paub dhau los tuaj yeem tiv nrog nws daim ntawv thov. Lub tshuab installation zoo ib yam li kev siv plaster rau phab ntsa.
Cov khoom tiv thaiv dej tsis zoo dua li lwm yam khoom siv dej tsis zoo. Ua raws li cov phab ntsa saum npoo, rwb thaiv tsev los ua ib qho kev tiv thaiv kev tiv thaiv ya raws tau ntau xyoo.
Tim txheej txheej hom waterproofing
cov ntaub ntawv siv raws li Caas waterproofing muaj qhov siab ntom ntom, uas ua rau lawv tiv taus ya raws ntawm sab nraud ib puag ncig. Ntawm ntau yam khoom siv hauv tsev, ntau hom txheej txheej waterproofing yog txawv:
- polymer mastics yog tus cwj pwm los ntawm lub neej txee ntev yam tsis pom qhov tsis xws luag;
- polymer cement mortars tsis yog ua haujlwm xwbmuaj nuj nqi ntawm kev tiv thaiv ya raws, tab sis kuj muaj ib tug firming nyhuv;
- Astringent plaster muaj hydrophobic, tsis-shrinking cov khoom xyaw;
- bituminous mastics, uas tsis yog qhov ntxim nyiam, tab sis muaj cov dej tawm zoo heev.
Txhua cov ntaub ntawv tau piav qhia saum toj no muaj ntau qhov zoo thiab qhov tsis zoo. Kev xaiv yog ua los ntawm tus kheej, suav nrog cov yam ntxwv ntawm tus qauv.
YBitumen waterproofing
Hom kev tiv thaiv dej tsis zoo no muaj cov khoom noo noo zoo thiab tuaj yeem tiv taus lub dav hlau thauj mus txog 0.2 MPa. Qhov tsis zoo yog tias lub neej kev pabcuam tsis ntev txaus, uas, yog tias siv tau zoo, tsuas yog 6 xyoo xwb. Tsis tas li ntawd, mastic poob nws cov khoom ntawm qhov kub ntawm 0 degrees thiab nws yuav ua rau tawg.
Qhov kev tiv thaiv dej tsis zoo no tsis tshua siv los ua cov khoom tseem ceeb ntawm cov txheej txheem dej. Feem ntau, nws ua hauj lwm pab raws li ib tug primer rau kev siv zog compounds.
Ntau yam cement waterproofing
Hnub no, muaj ntau ntau yam ntawm cov cement sib tov uas muaj cov khoom tiv thaiv dej siab.
Lawv muaj qee qhov sib txawv:
- Cov khoom sib xyaw uas muaj cov khoom siv tsis zoo. Nws yog kev cai siv cov tshuaj xws li tshuaj tsuag thiab nrog spatula.
- cement-sand waterproofing yog siv rau cov hauv paus monolithic. Feature yogQhov tseeb tias tom qab daim ntawv thov nws yuav tsum tau moistened txhua 15 hnub kom txog thaum qhuav tag, thiaj li tsis txhob tawg ntawm cov khoom. Cov khoom muaj xws li Portland cement, gypsum thiab aluminous cement.
- Cement-polymer waterproofing yog qhov txawv ntawm qhov muaj cov khoom ntxiv hauv cov khoom sib xyaw uas tsim cov txheej zoo li roj hmab.
Kev xaiv cov khoom nyob ntawm qhov chaw uas nws siv, nrog rau qhov xav tau.
Cement txheej hom waterproofing
Cement waterproofing muaj ntau cov txiaj ntsig uas ua kom nws nrov nrog cov neeg tsim khoom:
- txheej txheem thov yog zoo ib yam li plastering, yog li cov waterproofing muaj siab ceev thiab txheej thickness;
- khoom siv yooj yim thiab txhim khu kev qha, vim nws tsuas muaj 2 yam khoom: cement thiab kua hauv paus;
- siv cov dej tsis zoo tuaj yeem tiv taus siab txog 6 qhov chaw, uas tsis yog txhua yam khoom tuaj yeem khav theeb.
Vim nws cov khoom tshwj xeeb, cov cement mortar waterproofing yog siv los ua kom tiav tsis tsuas yog sab nrauv thiab sab hauv phab ntsa ntawm cov tsev, tab sis kuj rau cov pas dej da dej, saunas, qhov twg muaj cov av noo siab.
Cov nuances ntawm kev thov cov cement-based waterproofing
Kev siv cov cement-based waterproofing yog ib txoj kev yooj yim, yog li txawm tias tus pib tuaj yeem ua tau. Nws muaj ob peb theem:
- Qhov saum npoo ua ntej siv cement waterproofing yog ntxuav ntawm av, plua plav thiab seem ntawm lwm yam kev tsim khocov ntaub ntawv.
- phab ntsa yog dej saturated.
- Npaj cov dej sib tov los ntawm cov dej emulsion thiab cov cement qhuav.
- Cov tuab tuab yog siv rau saum npoo ntawm phab ntsa nrog spatula thiab leveled siv lub tsev theem.
Tom qab siv ib txheej, cia nws qhuav rau lub sijhawm uas tau teev tseg hauv cov lus qhia ntawm pob khoom sib tov. Lub sijhawm no, nws yog ib qho tseem ceeb kom tsis txhob ua txhaum kev ncaj ncees ntawm txheej.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm txheej txheej waterproofing
cement-based waterproofing tau siv los ntawm cov neeg tsim khoom tau ntau xyoo. Cov tshuaj zoo npog qhov thiab cov kab nrib pleb hauv cov phab ntsa los ntawm cov dej noo tuaj yeem nkag mus. Cement waterproofing yog siv rau sab nrauv thiab sab hauv kho kom zoo nkauj, thiab kuj yog ib tug zoo primer rau tom qab painting los yog tiling.
Vim qhov tuab ntawm cov txheej txheem dej tsis zoo, cov khoom siv cement-based dej-repellent kuj siv los ua rwb thaiv tsev. Thaum siv tau zoo thiab qhuav tag, qhov sib tov muaj lub neej ua haujlwm ntev yam tsis muaj kev tawg lossis lwm yam tsis xws luag.
Khoom zoo
Cement raws waterproofing muaj ntau qhov zoo:
- khoom siv ib puag ncig thiab tsis muaj tshuaj lom;
- kho sai: kev ua tiav tiav tuaj yeem pib sai li 2 lub lis piam tom qab siv qhov sib tov;
- tsis xav tau kev kho ntau zaus rau txheej txheej dej;
- muaj peev xwm ntawm daim ntawv thov ntawm qhov chawtxhua daim ntawv;
- tsis muaj cov cuab yeej siv yooj yim yuav tsum tau siv: tsuas yog spatula, txhuam thiab qib tsev siv tau;
- cov khoom siv qis.
Cov txiaj ntsig tau piav qhia saum toj no feem ntau txiav txim siab thaum xaiv cov dej tsis zoo rau kev kho kom zoo nkauj sab hauv. Qhov zoo ntawm cov khoom tso cai rau nws siv rau hauv qhov chaw uas muaj cov av noo siab yam tsis muaj kev cuam tshuam zoo.
Qhov tsis zoo ntawm cov cement sib tov
Txawm hais tias txhua qhov pom tau zoo ntawm kev siv cov cement mortar ua cov dej tsis zoo, nws muaj ob peb qhov tsis zoo:
- txheej txheem ntawm kev siv cov sib tov rau ntawm phab ntsa yuav siv sij hawm ntev;
- Tsis txhob siv cov tshuaj khib nyiab zoo tib yam ntawm cov cement thiab xuab zeb ua cov dej tsis muaj dej (nws tsis muaj elasticity thiab nws yooj yim tawg), cov khoom ntxiv yuav tsum tau ntxiv kom cov khoom muag muag;
- yog tias tawg, nws raug nquahu kom tshem tawm cov txheej txheem ntawm qhov tawg thiab siv cov sib tov dua;
- txawm tias lub neej ua haujlwm ntev npaum li cas, phab ntsa hauv qab cov dej tsis sib haum yog maj mam saturated nrog noo noo, ua rau kev puas tsuaj ntawm cov cement txheej; Tom qab ob peb xyoos lawm, cov txheej txheem dej tsis zoo yuav tsum tau hloov, vim tias cov dej noo tuaj yeem nkag mus rau ntawm phab ntsa thiab ua rau nws puas tsuaj.
Cov khoom npaj niaj hnub no muaj cov khoom tsim nyog los txuas ntxiv lub neej kev pabcuam, yog li ntawd, lawv tsis muaj feem ntau ntawm qhov tsis txaus uas tau piav qhia saum toj no. Lawv suav nrog cov khoom xws li dejemulsion, nplua cement, quartz xuab zeb, tshuaj ua kom elasticity thiab viscosity, crystallizing polymer los pab teeb lub mortar.
Kev xaiv cov dej tsis zoo rau chav nyob yog nyob ntawm qhov yuav tsum tau ua kom zoo thiab ua haujlwm ntev ntawm cov khoom. Qhov kev txiav txim siab tseem tuaj yeem yog qhov pheej yig thiab muaj cov khoom ntawm cov cement sib tov. Txawm li cas los xij, nws muaj cov khoom zoo heev uas tsis tuaj yeem cuam tshuam lub sijhawm.
