Ua kom haum waterproofing yuav tsum tau ua kom moistened?

Thaum tsim kho cov kua dej waterproof (xws li polymer Maas-bibed waterproof txheej, Polyurethane Waterproof Txheej Txheem, lwm yam.), Cov ntub dej uas yuav tsum tau txiav txim siab kom txiav txim siab raws li cov khoom lag luam tshwj xeeb thiab chaw tsim kho, tab sis feem ntau ua raws li cov hauv qab no:

1. Cement raws li qhov hloov dej tsis haum (xws li js waterproof txheej, K11 Waterproof slurry, lwm yam.)

   • Lub hauv paus nto yuav tsum muaj noo tab sis tsis muaj cov dej pom tseeb:Hom khoom siv no feem ntau yuav tsum tau lub hauv paus sab hauv kom nyob noo tab sis tsis muaj dej tsub zuj zuj (feem ntau hu ua “Qhuav nto thiab ntub hauv”).

   • Lub hauv paus noo kev ua haujlwm muaj kev pab dej tsis zoo rau cov kev sib raug zoo nrog lub hauv paus txheej, thiab txwv tsis pub lub hauv paus qhuav saum npoo ntawm nqus dej noo dhau heev, ua rau txheej txheej kom tawg lossis hmoov.

     Cov Lus Qhia Ua Haujlwm: Txau dej kom ua kom cov hauv paus ua ntej tsim kho, thiab thov nws tom qab tsis muaj cov dej ntshiab ntws ntawm cov nplaim dej.

2. Polyurethane saj zawg zog waterproofing (Ib Leeg / Ob Chav Cheebtsam)

   • Lub hauv paus sab nto xav tau qhuav:Polyurethane txheej yog rhiab rau ya raws, thiab lub hauv paus sab saum toj xav tau kom huv si (Cov ntsiab lus noo noo yog feem ntau yuav tsum yog ≤8%), lwm yam npuas thiab Delamination yuav tshwm sim.

   • Tsuas yog: Qee cov polyurethanes (xws li cov hom ya raws txoj kev txhaj tshuaj) tuaj yeem thov ntawm ntub dej substrates, Tab sis lawv yuav tsum tau ua haujlwm nruj raws li cov lus qhia khoom lag luam.

3. Kev Ceev Kev Ceev Siab

   • Kev kho mob hauv paus yog qhov tseem ceeb:Txawm hais tias ntub lossis qhuav, Lub substrate yuav tsum yog ruaj, tiaj, Dawb ntawm cov roj thiab cov ntaub ntawv xoob. Cov kab nrib pleb thiab qhov yuav tsum tau sau nrog kho cug ua ntej.

   • Ambient Kub thiab Vaum:Zam kev tsim kho hauv cov huab cua siab thiab cua hlob los tiv thaiv dej los ntawm kev nqus tau sai heev (Cov Khoom Siv Cement-based) lossis kev kho mob (polyurethane).

   • Cov lus qhia khoom yuav tsum yeej:Cov khoom lag luam sib txawv thiab cov khoom siv dej tsis muaj nyias yuav muaj cov kev xav tau sib txawv, Yog li nco ntsoov ua raws li cov lus qhia kev tsim kho muab los ntawm cov chaw tsim tshuaj paus.

Cov Lus Qhia Tshaj Tawm

• Cement raws li qhov hloov dej tsis haum: Lub substrate yog ntau txhim khu kev qha kom ntub dej, Tab sis tsis muaj dej pom nyob saum npoo.

• Polyurethane Waterproofing: Lub substrate yuav tsum qhuav.

• Txoj kev xeem: Siv cov ntawv nqus kom lo rau cov substrate. Yog tias tsis muaj qhov tseeb ntawm cov quav, Nws yog nyob rau hauv “tsis muaj dej pom” lub xeev

• Nco ntsoov paub meej tias cov khoom siv ua ntej kev tsim kho ua ntej kev tsim kho thiab ua ib thaj chaw me me kuaj kom ntseeg tau qhov ua tiav!

Yog tias lub hauv paus nto tsis moistened raws li yuav tsum tau thaum ua kev tsim cov kua dej tsis yooj ntub (Tshwj xeeb caas-based waterplof cov ntaub ntawv), Cov teeb meem nram no yuav tshwm sim:

1. Cement raws li qhov hloov dej tsis haum (xws li JS / K11 Txheej ci)

   • Txo Adhesio Adhesio

     • Lub hauv paus qhuav saum npoo yuav sai sai nqus cov dej noo hauv cov dej tsis muaj dej slurry, ua rau cov txheej uas tsis tuaj yeem ua kom lub zog, Thiab cov nplaum rau lub hauv paus txheej tsis muaj zog, uas yog tus nquag rau hollowing thiab delamination.

     • Tshwm sim: Tom qab ua tiav, Cov txheej tawv yuav raug nraus lossis khob ntawm tes, thiab tag nrho daim yuav tev tawm.

2. Tawg los yog hmoov ntawm txheej

   • Tom qab cov dej noo ntau dhau yog nqus tau, txheej txheej tsis tuaj yeem ua tiav cov tshuaj tiv thaiv vim tsis muaj dej, thiab cov nplaim hluav taws dhau mus sai heev, tsim cov kab nrib pleb lossis xoob txheej hmoov.

3. Tsis ua hauj lwm ntawm kev ua haujlwm tsis muaj dej

   • Micro kab nrib pleb thiab hollots yuav tsim dej seem, thiab dej yuav nkag los ntawm cov ntsiab lus tsis muaj zog, ua rau tag nrho ua tsis tiav ntawm cov dej tsis muaj dej

4. Polyurethane Waterproof Txheej Txheem

   • Tsawg kev cuam tshuam los ntawm qhuav substrate

     • Polyurethane nws tus kheej xav tau ib substrate qhuav, Tab sis yog tias lub substrate yog ib yam nkaus thiab qhuav heev thiab ntxeem tau (xws li ib qho qub xis mas substrate), Tej zaum nws yuav tsim nyog los ua ntej siv primer (xws li Epoxy Primer) Txhawm rau ntim cov pores, los yog:

     • Cov txheej yuav nkag mus rau ntau dhau rau hauv substrate, ua rau tuab tuab

     • Yog tias hmoov av ntawm lub substrate tsis huv, Cov nplaum yuav raug txo kom tsawg.

5. Cov xwm txheej tshwj xeeb (Kev kub siab / cua ib puag ncig)

   • Txawm hais tias cov khoom nws tus kheej tsis tas yuav muaj cov ntsiab lus noo noo (xws li ib co acrylic coatings), Hauv huab cua kub thiab cua, Ib substrate qhuav yuav ua kom nrawm ntawm cov cua noo los ntawm txheej, ua rau nyob rau hauv:

   • Shrinkage thiab tawg ntawm txheej;

   • Discontinuous zaj duab xis tsim thiab pinholes

Yuav kho li cas ib tug unmoistened substrate?

1. Txoj Cai Sawb Waterproofing: Tsum tsis txhob siv tam sim ntawd, Txau dej rau ntawm thaj chaw pleev xim rau kev saib xyuas (Yog tias qhov chaw pib tsis tiav), los yog txhuam nws tawm thiab rov ua dua lub substrate ua ntej kev tsim kho

2. Polyurethane Waterproofing: Xyuas kom meej tias lub substrate yog qhuav thiab hmoov av dawb, thiab txhuam thiab thov tshwj xeeb primer yog tias tsim nyog

Cov lus tseem ceeb

• Txoj Cai Sawb Waterproofing: Tsis ntub lub hauv paus nto ≈ “cia cov txheej sib tuag ntawm kev nqhis dej”, ncaj qha ua rau kev sib raug zoo thiab lub zog

• Lwm Cov Ntaub Ntawv: Lub hauv paus nto yuav tsum tau kho nruj me ntsis raws li cov khoom yuav tsum tau ua, qhuav ≠ tsis muaj kev kho mob (Kev tu thiab theem yog tseem yuav tsum tau ua

• Qhov Kawg Tswv Yim: Ua ntej kev tsim kho, so lub hauv paus saum npoo nrog tus txhuam hniav ntub kom ua tiav ib “Peopated DUA DEG” lub xeev (tsis muaj dej pom, me ntsis txias rau kov) Rau qhov kev nyab xeeb tshaj plaws.
