Cov chaw tsim kho me me thiab cov khw muag khoom loj muab cov neeg siv khoom xaiv ntau yam sib xyaw rau ntau lub hom phiaj. Cov thawj coj nyob rau hauv cov nqe lus ntawm kev muaj koob meej yog nyob los ntawm cov khoom ntawm nto moo German kev txhawj xeeb Henkel, uas yog tsim nyob rau hauv lub Ceresit hom. Nyob rau hauv lub rhawv ntawm kev tsim kho cov khw muag khoom koj tuaj yeem pom ntau yam nplaum ntawm hom no, qib sib tov, primers, grouts rau cov vuas ceramic thiab ntau lwm yam khoom.
Peb yuav tsom mus rau cov dej tsis sib haum uas tsim los ntawm cov chaw tsim khoom no raws li Ceresit CR-65. Hauv tsab xov xwm no, peb yuav pom cov yam ntxwv zoo li cas cov khoom no tau txais txiaj ntsig, nws muaj dab tsi, yuav siv li cas kom raug, qhov sib tov (waterproofing) CR-65 tuaj yeem siv.
Scope of application
Kev txiav txim los ntawm cov neeg siv khoom tshuaj xyuas, Ceresit sib tov yog npaj raunqa tawm waterproofing ua hauj lwm ntawm non-deformable pob zeb hauv paus. Cov muaj pes tsawg leeg tuaj yeem siv rau txhua qhov chaw (qab nthab, phab ntsa, pem teb) txhawm rau tsim cov txheej txheem dej tsis zoo. Nyob rau tib lub sijhawm, nws tuaj yeem siv rau hauv tsev thiab sab nraum zoov. Lub luag haujlwm tseem ceeb ntawm cov rwb thaiv tsev zoo li no yog los tiv thaiv qhov tshwm sim ntawm dampness thiab nkag mus ntawm noo noo mus rau hauv cov tsev. Kev tshuaj xyuas cov neeg siv khoom qhia tias Ceresit CR-65 waterproofing sib tov yog feem ntau siv:
- Rau cov pob zeb tsis muaj dej thiab cov av cib.
- Thov txheej tiv thaiv sab hauv thiab sab nraud hauv qab daus thiab hauv av.
- Tsim cov dej tsis muaj dej hauv cov chav nrog cov av noo siab: chav ua noj, chav dej, chaw ua haujlwm.
- Rau cov dej tsis muaj dej monolithic pas dej, da dej, tso dej tso dej.
- Raws li txheej tiv thaiv los tiv thaiv kev puas tsuaj ntawm cov av hauv av thiab cov qauv hydraulic los ntawm dej thiab te.
- Tiv thaiv lub hauv paus ntawm cov tsev.
Basic nta
Dry mix (waterproofing) muaj Portland cement, polymer nrog cov ntxhia ntxiv thiab ntau yam hloov pauv. Cov khoom yog muag nyob rau hauv daim ntawv ntawm ib tug qhuav muaj pes tsawg leeg, ntim rau hauv 25 kg hnab. Kev txiav txim los ntawm cov lus tawm tswv yim los ntawm cov neeg siv khoom, hauv lub xeev hardened, txheej txheej muaj cov khoom nram qab no:
- zoo vapor permeability;
- tsis kub tsis kam;
- ib puag ncig phooj ywg;
- dej resistant;
- zog;
- no shrinkage;
- hydrophobicity;
- resistance ntsev thiab alkali.
Cov tshuaj ua kua dej zoo kawg nkaus poob rau hauv cov kab nrib pleb, kev nyuaj siab thiab qhov hws ntawm qhov chaw, ua rau cov txheej txheem txhim khu kev qha uas tiv thaiv kev nkag mus ntawm cov dej me me.
Ceresit CR-65 Waterproofing Compound: Specifications
Tam sim no cia saib cov yam ntxwv ntawm cov khoom no. Cov ntaub ntawv los ntawm cov chaw tsim khoom, nyob rau ntawm cov khoom ntim, hais hauv qab no:
- Txhawm rau npaj cov khoom xyaw ua haujlwm rau 25 kg ntawm qhuav sib tov, koj yuav xav tau 6.5-7 liv kua. Yog hais tias qhov loj yuav tsum tau thov nrog ib tug spatula, tus nqi ntawm cov dej yuav tsum tau txo mus rau 5.5 litres.
- Cov kev npaj sib tov yog siv tau rau thawj ob teev.
- Ua haujlwm ntawm kev thov cov txheej txheem dej yuav tsum nyob ntawm qhov kub ntawm +5 txog +30 degrees.
- Hummidity hauv chav thaum lub sijhawm kho saum npoo yuav tsum tsis pub tshaj 60%.
- Adhesion ntawm cov muaj pes tsawg leeg nrog nto - 1.0 MPa.
- Compressive zog tom qab ob hnub - 10.0 MPa, thiab tom qab 28 hnub - 15.0 MPa.
- Cov khoom sib xyaw tawv tau yooj yim zam ntau dua 100 lub voj voog khov.
- Cov chaw kho mob tuaj yeem siv tau ntawm qhov kub ntawm -50 txog +70 degrees.
Peb hnub tom qab siv cov khoom xyaw, koj tuaj yeem pib txhim kho cov vuas luaj ceramic. Kev ua siab ntevcov txheej tau txais hydraulic loads 5 hnub tom qab thov.
Ua ntej koj mus tom khw rau kev yuav khoom, txhua tus tswv yuav xav nkag siab tias tus nqi zoo npaum li cas Ceresit CR-65 waterproofing sib tov. Kev siv cov khoom siv ua lub luag haujlwm tseem ceeb hauv cov kev suav no. Cov chaw tsim tshuaj paus qhia peb tias rau kev kho mob ntawm txhua square ntawm nto peb xav tau los ntawm 3 mus rau 8 kg ntawm qhuav mix. Daim duab no txawv nyob ntawm qhov tuab ntawm txheej tiv thaiv thiab tus naj npawb ntawm kev kho mob.
Npaj lub hauv paus rau kev ua haujlwm
Ua ntej pib ua daim ntawv thov ntawm cov tshuaj tiav, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo npaj qhov chaw. Nws yuav tsum txaus ntom, txawm thiab ruaj khov. Ua ntej ua tiav, nws raug ntxuav ntawm ntau yam kab mob thiab tsis muaj plua plav. Kev poob ntawm plaster, xim thiab txhua yam delamination yuav tsum raug tshem tawm. Tag nrho cov kab nrib pleb thiab kev nyuaj siab yog embroidered thiab smeared nrog tshwj xeeb compounds.
Ib qho huv si thiab txawm tias lub hauv paus tau nchuav nrog dej ntau, tiv thaiv nws cov khoom txuam thiab tsim cov streaks. Tom qab ntawd, koj tuaj yeem thov qhov sib tov. Cov khoom siv dej tsis zoo ntawm cov khoom lag luam no tuaj yeem siv ua ke nrog Ceresit CO-81 cov tshuaj tiv thaiv dej, uas txhim kho kev ua haujlwm ntawm thawj cov khoom siv ntau zaus.
Yuav ua li cas npaj kev daws teeb meem?
Txhawm rau zam qhov yuam kev thaum ua haujlwm, koj yuav tsum paub yuav ua li cas npaj Ceresit waterproofing sib tov. Kev tshuaj xyuasCov neeg siv khoom thiab cov chaw tsim khoom tau hais tias kev ntsuas nruj me ntsis ntawm cov dej nrog qhov kub ntawm +15 txog +25 degrees yuav tsum tau muab coj los sib tov. Ob qho tib si sib xyaw ua ke thiab sib xyaw nrog cov khoom siv qis qis kom txog thaum cov pob ploj. Tom qab thawj kneading, qhov sib tov yog tso rau 5 feeb, tom qab uas nws yog kneaded dua.
Cov neeg uas tseem tsis tau ntsib cov khoom no tej zaum xav tias nyuaj npaum li cas cov kua dej tsis sib haum (Ceresit CR-65/25) ua haujlwm nrog. Cov neeg siv khoom tawm tswv yim qhia tias tsis muaj dab tsi nyuaj hauv cov txheej txheem no. Leej twg tuaj yeem ua haujlwm zoo li no. Tsis tas li ntawd, cov neeg siv khoom hais txog qhov zoo ntawm cov khoom siv no. Kev txiav txim los ntawm lawv cov kev tshuaj xyuas, nws yuav kav ntev yam tsis muaj teeb meem.
Waterproofing "Ceresit" yog siv tsawg kawg yog 2 txheej. Thaum thawj kis, ib tug muffler yog siv. Tag nrho cov khaubncaws sab nraud povtseg yog siv nrog lub spatula lossis txhuam hauv cov lus qhia hla ntawm lub khov (tab sis tsis qhuav) thawj txheej. Yog li ntawd, tag nrho qhov chaw kho mob yuav tsum muaj txheej txheej ntawm tib lub thickness. Kev ua haujlwm ntawm cov txheej tuaj yeem pib tom qab 5 hnub.
