Kev siv cov khoom sib xyaw polymer thaum tsim cov qhob screed yog qhov tsis tseem ceeb rau kev ua tiav lub zog ua kom muaj zog siab thiab txo qis kev tsim cov hmoov av ntawm nws saum npoo. Polyurethane impregnation yog qhov tsim nyog tshaj plaws rau qhov no, muab cov yam ntxwv zoo ntawm cov khoom.

Peculiarities

Txhawm rau txhim kho cov dej noo tiv taus thiab lub zog muaj zog ntawm cov pob zeb monolithic, nws tau siv cov ironing. Cov txheej txheem thev naus laus zis no suav nrog kev siv cov nplaum tshwj xeeb uas ua rau lub qhov hws, uas yog qhov tsis zoo ntawm cov khoom thiab ua kom nrawm dua . Ib qho ntxiv, tsis muaj kev kho tshwj xeeb, xws li cov plag tsev thiab lwm yam txheej txheem nqus dej ntau heev, ua hmoov av thiab sai sai yog tias nyob sab nraum zoov.

Txhawm rau tiv thaiv qhov no, cov kws tshaj lij siv ntxiv dag zog rau cov tshuaj polymer. Ib qho ntawm cov khoom xav tau uas ua nws txoj haujlwm zoo yog polyurethane impregnation rau pob zeb ua . Cov khoom lag luam yog cov kua viscosity qis uas ua rau lub qhov hws ntawm cov khoom, nkag mus rau hauv nws cov tuab los ntawm 5-8 hli. Cov impregnation muaj ib qho kev sib xyaw ua ke thiab tsis xav tau kev npaj ua ntej thov: nws tsuas yog yuav tsum tau sib tov kom huv si kom du.

Polymer kua muaj peev xwm txhim kho cov nplaum ntawm cov pob zeb ua ke nrog cov txheej sib txawv.

Cov khoom tsim nyog rau kev kho vaj tse qub, puas, nrog rau tsim cov qauv tshiab los ntawm nws . Polyurethane yog cov khoom muaj ntau yam uas tuaj yeem nqus tau sai thiab tsim qhov xav tau ceev yam tsis cuam tshuam nrog dej los ntawm ib puag ncig. Cov khoom lag luam muaj cov yam ntxwv hauv qab no muaj txiaj ntsig zoo xws li:

• siab yas, tiv taus kub heev;
• nce qhov cuam tshuam tiv thaiv cov khoom los ntawm 2 zaug;
• nce qhov hnav tsis kam ntawm cov pob zeb ua 10 zaug;
• kev siv cov tshuaj muaj pes tsawg leeg tso cai rau koj tshem tawm cov hmoov av tag;
• tawv tawv rau cov pawg uas lees paub (M 600);
• muaj peev xwm siv tau ntawm qhov kub tsawg (txog -20 °);
• teeb tsa nrawm hauv ib hnub, muaj peev xwm ua haujlwm nrog hnyav hnyav tom qab 3 hnub;
• yooj yim impregnation thev naus laus zis uas tsis xav tau kev paub thiab txuj ci tshwj xeeb;
• qhov muaj pes tsawg leeg tuaj yeem siv rau qib qib pob zeb uas pheej yig;
• muab cov txiaj ntsig los tiv thaiv plam thiab zoo nkauj ntawm cov khoom tom qab daim ntawv thov ua haujlwm.

Tau kawg, cov npe teev tseg yog qhov ua tau zoo ntawm polyurethane impregnation, ntxiv rau nws cov nqi qis. Ntawm qhov tsis zoo ntawm tus txheeb ze, ib tus tuaj yeem tso npe xav tau siv cov polymer tsuas yog tom qab qhov ziab zaum kawg ntawm cov qauv.

Thiab tseem, yog tias cov qhob noom xim kasfes muaj qhov ua tsis raug, piv txwv li, silicon dioxide, tom qab ntawd polyurethane tuaj yeem ua rau muaj kev ntxhov siab hauv cov khoom, ua rau muaj cov tshuaj alkali-silicate.

Hom thiab lub hom phiaj

Cov tshuaj tsis haum rau cov pob zeb yog polymeric (organic), lawv qhov kev ua yog txhawm rau ua kom muaj zog, tiv taus ya raws, tiv taus cov tshuaj txhoj puab heev. Hom neeg tsis muaj zog ntawm tus neeg sawv cev ua haujlwm sib txawv. Cov tshuaj lom neeg hauv lawv cov muaj pes tsawg leeg, thaum cuam tshuam nrog cov txheej txheem ua vaj tse ua ke, tau txais inertness thiab yaj. Vim qhov no, cov khoom tau txais cov txiaj ntsig zoo xws li dej tsis kam thiab qhov tsim nyog ua kom tawv. Muaj hom nrov ntawm impregnations nyob rau hauv cov nqe lus ntawm kev muaj pes tsawg leeg.

Epoxy ob-tivthaiv sib xyaw ntawm cov tshuaj thiab cov tawv tawv (phenol) . Cov khoom no muaj qhov tshwj xeeb los ntawm kev txo qis, ua kom tsis muaj zog, ua kom muaj zog thiab muaj dej noo permeability tsawg. Lawv tau siv los tsim cov qauv rau cov tsev tsim khoom thiab chaw ua haujlwm, hauv qab daus, pas dej da. Tsis zoo li polyurethane, cov no tsis tiv taus lub cev hloov pauv thiab cov tshuaj lom hnyav.

Acrylic impregnation rau hauv pem teb - tiv thaiv zoo tiv thaiv tshav ntuj UV, ya raws thiab tshuaj chlorine sib xyaw. Txawm hais tias lawv khaws cov xim ntawm lub ntsej muag thaum lub sijhawm ua haujlwm tag nrho, lawv xav tau kev rov ua dua tshiab txhua 2-3 xyoos.

Polyurethane … Hais txog cov khoom muaj txiaj ntsig ntawm polyurethane, ib tus tsis tuaj yeem hais tsis tau nws cov khoom tiv thaiv vim muaj cov tshuaj organic thiab cov tshuaj polymer hauv cov tshuaj hnyav. Qhov no sib txawv ntawm cov khoom lag luam los ntawm lwm yam impregnations - hom khoom siv no tuaj yeem siv hauv huab cua sib txawv thiab huab cua puag. Tsis tas li ntawd, kev pub mis rau menyuam sai thiab yooj yim thov, thiab tsis kim.

Vim yog qhov ua tau zoo ntawm kev pleev xim, kev nkag mus tob tob rau qhov pom tsis pom tom qab ntawm lwm tus neeg sawv cev, tsim los txhim kho kev nplaum rau cov hniav, pleev xim lossis lwm yam xim txheej. Ua tsaug rau nws cov yam ntxwv txhua yam khoom siv siv sijhawm ntev dua.

Thiab kuj ntawm kev muag khoom koj tuaj yeem pom cov xim sib xyaw thiab tsis muaj xim rau tshem cov hmoov av ntawm cov pob zeb thiab muab nws zoo saib. Lawv muaj feem cuam tshuam rau ob lub tsev tsim khoom thiab rau thaj chaw nyob.

Cov kev xaiv

Cov qhob yooj yim yuav tsum tau pleev xim nrog cov tshuaj tiv thaiv vim nws cov qauv ntxeem tau. Thaum lub sijhawm ua kom cov dej hauv cov cement, huab cua, dej, thiab cov cement slurry nyob rau hauv daim ntawv ntawm cov gel tuaj yeem pom hauv cov kab noj hniav. Qhov no ua rau lub zog tsis muaj zog ntawm cov khoom lag luam thiab ua rau lawv lub neej ua haujlwm luv. Txawm li cas los xij, cov pob zeb tuaj yeem hloov pauv mus rau hauv pob zeb monolithic siv impregnations. Cov kev cai dav dav rau kev xaiv ntawm impregnations:

• kev nyab xeeb cov txheej txheej tom qab siv cov khoom sib xyaw ua ke, tsis tso cov khoom puas tsuaj, cov pob zeb ua haujlwm yuav tsum tsis txhob ntog;
• nws yog ib qho tseem ceeb uas yuav tau ua tib zoo saib xyuas lub hom phiaj ntawm kev daws teeb meem , lawv cov khoom ua haujlwm, xws li hnav tsis kam, tiv taus dej, hluav taws xob ultraviolet, kub thiab lwm yam sab nraud;
• kev pom tau zoo nrog lub substrate , zoo nkag mus thiab adhesion;
• tangible tshwm sim nyob rau hauv cov nqe lus ntawm txo cov hmoov av tsim;
• ntxim nyiam tsos.

Polyurethane impregnation txaus siab rau txhua qhov qauv no, nws yog tus uas yog txoj hauv kev zoo tshaj plaws los txhim kho kev ua tau zoo ntawm cov qauv ua vaj tsev. Ntxiv rau kev ntxiv dag zog rau cov khoom siv, tiv thaiv nws cov hnav ua ntej, txiav tawm thiab ua kom lub neej kev pab cuam, polyurethane muaj pes tsawg leeg tso cai rau koj muab cov qauv ua kom zoo nkauj, sib sib zog nqus thiab nplua nuj xim vim muaj peev xwm ua kom cov xim daws tau.

Hom kev thov

Polyurethane impregnation tuaj yeem siv tsis tau tsuas yog ua pob zeb, tab sis kuj tseem rau lwm cov pob zeb hauv av, tab sis cov thev naus laus zis ib txwm tsis hloov pauv

• Thawj kauj ruam yog nrog cov cuab yeej sib tsoo cov pob zeb ua tiav yog qib , tshem cov cement mis, xoob txheej, roj, txheej tau txais los ntawm kev ironing.
• Ib txhais tes sib tsoo yog siv los ntxuav cov pob qij txha , txhuam txhuam tshem tawm cov khoom sib xyaw ntawm cov cement, xuab zeb. Yog li, qhov hws ntawm cov khoom siv tau qhib.
• Kev sib tsoo peb-theem ntxiv yog txhawm rau kom tau txais tus qauv muab ntxig (txiav pob zeb tsoo) . Ua ntej, kev ntxhib yog nqa los ntawm 2-5 hli, tom qab ntawd sib tsoo me ntsis, thaum kawg - sib tsoo nrog cov nplua -nplua abrasive.
• Nto tshem cov hmoov av siv lub tshuab nqus tsev.
• Ua raws los ntawm polyurethane-impregnated primer kom txog rau thaum txheej txheej zoo ib yam. Qhov sib tov yuav tsum tsis pub tso rau hauv daim ntawv ntawm puddles.
• Rau qib sib txawv ntawm cov pob zeb (M 150 - M 350), siv 3 lub tsho loj . Thaum screed qhob ntawm ib pawg ntau dua M 350, ntxiv rau cov cib, slate thiab cov vuas luaj ceramic, 2 txheej yog txaus. Rau qhov no, cov khoom siv xws li "Politax" yog qhov tsim nyog.
• Txhua txheej yuav tsum tau muab ziab kom qhuav … Ntawm qhov kub ntawm 0 °, ziab yuav siv sij hawm tsis pub tsawg tshaj 6 thiab tsis pub ntev tshaj 24 teev, ntawm qis dua, rho tawm kub, tsis pub tsawg dua 16 thiab tsis ntau dua 48 teev. Kev xeem daim ntawv thov ntawm impregnation yuav pab txiav txim siab kev siv polyurethane.

Txhawm rau txuag nyiaj, koj tsis tuaj yeem thov 3 txheej ntawm kev daws, tab sis tom qab ntawd saum npoo yuav tsis muaj qhov ci ci.

Txhawm rau muab lub zog ntau dua, ntawm qhov tsis sib xws, nws raug nquahu kom ua cov txheej ntxiv . Polyurethane impregnation muab kev nkag mus rau thoob plaws tag nrho cov tuab ntawm cov pob zeb, txhim kho cov khoom siv dag zog ntawm cov khoom siv thiab nws cov tshuaj tiv thaiv, uas lav tau qhov nce hauv kev pabcuam lub neej ntawm cov qauv los ntawm 2-3 xyoos, thiab tseem yooj yim cov txheej txheem rau kev tswj txheej..
