Yuav kom muaj lub tswv yim txog kev tiv thaiv dej ntawm cov qauv tsev, nws yog ib qho tsim nyog los paub txog cov khoom siv yooj yim uas ua rau lub tsev. Ib lub tsev feem ntau yog ua los ntawm cov pob zeb ua vaj tse, cib, pob zeb, thiab cov av nplaum. Cov khoom siv no yog tsim los ntawm cov siv lead ua los ntawm carbonate, silicate, aluminates, thiab oxides uas muaj cov pa oxygen ntau thiab cov pab pawg hydroxyl. Cement yog cov khoom tseem ceeb ntawm cov pob zeb ua vaj tse. Cov pob zeb ua vaj tse yog tsim los ntawm kev sib xyaw ntawm cov cement thiab dej. Cov kev sib xyaw no hu ua hydration.

Vim yog qhov tshwm sim ntawm cov tshuaj hydration, ntxiv rau cov silicate compounds uas ua rau cov cement nws qhov tawv thiab lub zog, kuj tseem muaj cov khoom calcium hydroxide. Calcium hydroxide tiv thaiv cov reinforcement los ntawm kev xeb vim tias cov hlau tsis tuaj yeem xeb hauv cov xwm txheej alkaline heev. Feem ntau, cov pob zeb ua kom pom pH siab dua 12 vim muaj calcium hydroxide.

Thaum calcium hydroxide mus txog carbon dioxide, calcium carbonate yuav tsim. Qhov kev tshuaj tiv thaiv no hu ua carbonation. Cov pob zeb yuav tawv, thiab qhov permeability yuav txo qis thaum lub sijhawm tshuaj tiv thaiv no. Ntawm qhov tod tes, calcium carbonate txo cov pH ntawm cov pob zeb kom txog li 9. Ntawm cov pH no, cov txheej oxide tiv thaiv uas nyob ib puag ncig cov hlau reinforcing tawg, thiab xeb yuav ua tau.

Dej yog ib qho tseem ceeb rau cov tshuaj hydration. Kev siv dej ntau npaum li cas muaj lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm cov pob zeb. Lub zog ntawm cov pob zeb nce ntxiv thaum siv dej tsawg dua los ua cov pob zeb. Qhov muaj dej ntau dhau hauv cov pob zeb ua rau cov pob zeb ua rau cov pob zeb tsis ua haujlwm zoo. Yog tias lub tsev tsis raug tiv thaiv zoo los ntawm dej, lub tsev yuav raug puas tsuaj thiab lwj. Thaum dej nkag mus rau hauv cov pob zeb los ntawm nws cov qhov sib txawv capillary, lub zog ntawm cov pob zeb yuav ploj mus, thiab lub tsev yuav yooj yim rau xeb. Yog li ntawd, kev tiv thaiv dej tsis pub nkag yog ib qho kev tiv thaiv tseem ceeb.

Cov Khoom Siv Twg Yog Cov Khoom Siv Uas Siv Tau Hauv Cov Khoom Siv Tiv Thaiv Dej?

Raws li peb tau hais ua ntej lawm, txhua qhov ntawm cov qauv tsev txij hauv qab nthab mus rau ru tsev, xws li phab ntsa, chav dej, chav ua noj, sam thiaj, chav nres tsheb, terraces, ru tsev, cov thoob dej, thiab pas dej ua ke, yuav tsum tau tiv thaiv kom tsis txhob muaj dej rau lub tsev ruaj khov. Feem ntau sivcov ntaub ntawv rau kev tiv thaiv dej hauv cov tsevyog cov ntaub ntawv cementitious, bituminous membranes, kua dej tsis ua haujlwm, bituminous coatings, thiab polyurethane kua membranes.

Cov txheej txheem tiv thaiv dej feem ntau yog siv cov txheej bituminous. Bitumen yog cov khoom siv uas paub zoo, pheej yig, ua haujlwm tau zoo, thiab yooj yim siv. Nws yog ib qho txheej tiv thaiv zoo heev thiab cov neeg sawv cev tiv thaiv dej. Kev ua haujlwm ntawm cov khoom siv bitumen tuaj yeem ua kom nce ntxiv nrog cov khoom siv uas yoog tau zoo dua xws li polyurethane lossis acrylic-based polymers. Tsis tas li ntawd, cov khoom siv bitumen tuaj yeem tsim ua ntau hom, xws li kua txheej, daim nyias nyias, daim kab xev, cov khoom sau, thiab lwm yam.

Daim Kab Xev Tiv Thaiv Dej Yog Dab Tsi?

Dej ua rau cov tsev puas tsuaj, ua rau pwm, lwj, thiab xeb ua rau cov qauv tsis ruaj khov. Cov ntaub nplaum tiv thaiv dej uas siv rau kev tiv thaiv dej ntawm cov qauv yog tsim los tiv thaiv dej nkag mus rau hauv lub plhaub tsev. Kev siv cov ntaub nplaum tiv thaiv lub tsev kom tsis txhob muaj dej nkag los ntawm qhov qhib ntawm lub plhaub. Cov ntaub nplaum tiv thaiv dej ntws daws cov teeb meem dej noo thiab cua ntsawj nyob ib puag ncig lub plhaub tsev xws li qhov rooj, qhov rai, qhov ntsia hlau, qhov no ua rau lawv muaj txiaj ntsig zoo rau cov tshuab ru tsev.

Cov ntaub nplaum tiv thaiv dej BaumerkCov kab xev no yog ua los ntawm bitumen los yog butyl, siv tau rau qhov txias, ib sab yog coated nrog aluminium foil los yog xim mineral, lwm sab yog nplaum. Tag nrho cov kab xev muab kev tiv thaiv dej nrog kev nplaum rau ntawm ntau yam substrates xws li ntoo, hlau, iav, plaster, concrete, thiab lwm yam.

Kev xaiv daim kab xev nplaum kom raug yog qhov tseem ceeb rau kev tiv thaiv dej thiab ua kom lub tsev zoo dua. Koj yuav tsum tau qhia meej txog koj qhov xav tau. Yog li, koj xav tau dab tsi? Kev tiv thaiv UV, kev ua haujlwm nplaum zoo, kev ua haujlwm txias, lossis tag nrho cov no?Cov pab pawg tshuaj tiv thaiv dej ntawm Baumerk yeej ib txwm coj koj musxaiv cov kev daws teeb meem zoo rau koj lub tsev tiv thaiv dej.

Cov txiaj ntsig ntawm Bitumen Based Waterproofing Flashing Tape yog dab tsi?

Baumerk B SELF TAPE ALSiv rau kev tiv thaiv dej ntawm cov qauv yog daim kab xev tiv thaiv dej ua haujlwm zoo uas tuaj yeem siv rau ntau qhov chaw siv. Vim yog cov ntawv ci txhuas thiab cov khoom siv mineral coated sab saum toj, nws muab kev tiv thaiv UV. Tsis tas li ntawd, nws yooj yim siv. Tsuas yog txaus kom tev tawm cov zaj duab xis tshem tau ntawm B-SELF TAPE AL thiab nias kom ruaj khov rau ntawm qhov chaw nplaum.

Yog xav paub ntxiv txog kev tiv thaiv dej ntawm cov qauv, koj tuaj yeem saib peb cov ntsiab lus ntxiv, uas muaj npe hu uaKoj puas paub txhua yam txog kev tiv thaiv dej hauv cov tsev?
