Kab rov tav Vs. Vertical Wall Joints: Yuav Siv Li Cas Fiberglass Mesh Joint Daim Kab Xev Rau "Pre-Cracking Reinforcement"
Tso lus
Feem ntau sab nrauv phab ntsa plaster tawg tsis pib hauv nruab nrab ntawm lub vaj huam sib luag - lawv pib ntawm cov pob qij txha. Txawm hais tias nws yog kab rov tav kev tsim kho qhov sib koom ua ke los yog ntsug structural interface, txoj kev ntse dua yog los txhawb nqa ua ntej qhov tawg tshwm. Los ntawm kev siv fiberglass mesh sib koom daim kab xev rau cov seams ua ntej plastering, koj disperse tensile kev nyuaj siab rau hauv daim phiaj mesh es tsis txhob cia nws mloog zoo nyob rau hauv lub brittle mortar txheej.
Kab rov tav vs. Vertical Joints – txawv Stresses, txawv tswv yim
Kab rov tav pob qij txha (piv txwv li, hauv pem teb-theem txias pob qij txha) feem ntau yog los ntawm shear force thiab inter-storey txav. Daim kab xev yuav tsum nyob nruab nrab ntawm qhov sib koom ua ke, nrog qhov sib tshooj tsawg kawg ntawm 50 mm ntawm txhua qhov kawg.
Vertical pob qij txha (xws li, nruab nrab ntawm cov masonry thiab cov pob zeb ua vaj tse, los yog ntawm phab ntsa kev sib tshuam) muaj kev cuam tshuam ntau dua los ntawm thermal shrinkage, uas yuav ua rau cov kab nrib pleb tas li. Ntawm no, daim kab xev yuav tsum ncua tsawg kawg yog 100 hli ntawm txhua sab ntawm kev sib koom ua ke los tsim ib qho "dav-band" tawg-resistant cheeb tsam.
Cov txheej txheem peb-kauj ruam rau kev tiv thaiv daim ntawv thov
① Ntxuav lub substrate - Tshem tawm cov plua plav, roj, thiab cov khoom xoob; xyuas kom qhov sib koom ua ke yog qhuav, txwv tsis pub adhesion yuav raug cuam tshuam.
② Tso daim kab xev - Nias daim kab xev kom nruj raws li kev sib koom ua ke, siv lub squeegee tshem tawm cov npuas npuas thiab ua tiav kev sib cuag nrog lub hauv paus.
③ Npog nrog plaster - Siv lub tsho nyias nyias ntawm cov kab nrib pleb-resistant mortar hla daim kab xev. Lub mesh embeds rau hauv lub mortar, tsim ib tug integrated reinforced txheej nrog phab ntsa.
Vim li cas Fiberglass Mesh Hloov Paper Daim Kab Xev?
Fiberglass muaj lub zog tensile siab thiab qis elongation, zoo tiv thaiv sab hauv kev ntxhov siab los ntawm thermal expansion thiab contraction. Nws cov alkali-resistant txheej tiv thaiv cov corrosive los ntawm cov cement mortar, ua kom muaj kev pab cuam lub neej ntev dua li cov ntawv sib koom ua ke. Cov nplaum nplaum nplaum kuj tseem tshem tawm qhov xav tau ntawm cov nplaum ntxiv - huv, ceev, thiab ua haujlwm zoo.
Pre-cracking reinforcement yog hais txog kev hloov los ntawm kev kho reactive mus rau proactive tswj. Qhov sib txawv ntawm kab rov tav thiab ntsug pob qij txha dictate koj qhov kev tso kawm lub tswv yim, tab sis cov tub ntxhais enabler tseem yog daim kab xev cov neeg kho tshuab kev ua tau zoo thiab daim ntawv cog lus kev ntseeg siab. Pebfiberglass mesh daim kab xevyog engineered nrog alkali-stabilized sizing thiab optimized tack rau ntau yam sab nrauv substrates - thiab peb muaj nyob rau hauv-site qauv kuaj los xyuas qhov ua tau zoo ua ntej daim ntawv thov tag nrho. Qhov ntawd yog li cas koj xauv txhua qhov sib koom ua ke, ua ntej kev tawg muaj lub sijhawm pib.
