Glassfiber Mesh: Nkag siab Txoj Haujlwm Ntawm Kev Txhim Kho Hauv Cov Txheej Txheem Sab Nraud

A thin-coat exterior insulation system is a multi-layer cladding system where the reinforcement layer is embedded within a thin polymer-modified render coat of 3–7mm thickness. Cov tshuab no tau raug pov thawj los ntawm ntau tshaj 30 xyoo ntawm kev vam meej thoob ntiaj teb.

Qhov system feem ntau muaj plaub txheej txheej:txheej nplaum, txheej rwb thaiv tsev, txheej txheej txheej, thiab txheej txheej tiav. 

1. Phab ntsa substrate
Qhov no yog lub hauv paus txheej txheem- feem ntau yog pob zeb lossis masonry. Ua ntej thov, lub substrate yuav tsum huv si, suab, thiab tsis muaj kab mob los yog qhov chaw tsis sib xws uas yuav cuam tshuam rau adhesion.

2. Adhesive Txheej
Ib qho tshwj xeeb tsim cov khoom sib txuas siv los txuas cov rwb thaiv tsev rau cov substrate. Daim ntawv thov txoj kev muaj xws li ib puag ncig- qhov chaw lossis tag nrho- cov txheej txheem trowel, nrog rau thaj chaw sib txuas zoo feem ntau yuav tsum tsis pub tsawg dua 40% ntawm cov ntaub ntawv rwb thaiv tsev. Adhesive bears tag nrho cov load ntawm lub system, nrog mechanical anchors pab tsuas yog ntxiv fixation.

3. Txheej txheej rwb thaiv tsev
Feem ntau nthuav dav polystyrene (EPS) nrog qhov ceev ntawm 18-25kg / m³ thiab thermal conductivity tsawg dua lossis sib npaug li 0.039W / (m·k). Cov laug cam yuav tsum tau muab tso rau hauv ib qho kev sib txuas ua ke nrog staggered ntsug pob qij txha. Ntawm cov ces kaum, cov laug cam yuav tsum sib cuam tshuam rau kev txhim kho kev ruaj ntseg.

4. Base Render Coat
Qhov no yog thawj txheej ntawm cov txheej txheem reinforcement, thov ntawm 2-3mm thickness. Polymer- hloov kho cementitious render yog sib npaug ntawm qhov chaw rwb thaiv tsev, ib txhij embedded tej ntug-wrap mesh.

5. Glassfiber Mesh Layer – Cov Tub Ntxhais Kev Txhim Kho
Qhov no yog qhov twg fiberglass mesh yog positioned. Kev lag luam kev xyaum zoo tshaj plaws muab cov mesh nyob rau sab nraud thib peb ntawm tag nrho cov thickness. Daim ntawv thov ib ntus yog qhov tseem ceeb: tam sim ntawd tom qab siv lub hauv paus rendering, lub mesh yog tensioned thiab embedded siv trowel, ua hauj lwm los ntawm qhov chaw sab nraud kom tshem tawm wrinkles thiab xyuas kom meej tag nrho encapsulation.

Lub mesh txoj hauj lwm nyob ze ntawm qhov chaw tsis yog qhov kev txiav txim siab - nws ua kom muaj txiaj ntsig zoo tshaj plaws hauv kev tswj cov kab nrib pleb thiab tiv thaiv kev cuam tshuam.

6. Sab saum toj Render Coat
Ua ntej lub hauv paus render sets, ib txheej thib ob ntawm polymer- hloov render yog thov ntawm 1-2mm thickness, tsuas yog txaus los npog lub mesh thaum tso cai rau nws kev ntxhib los mos nyob twj ywm faintly pom. Kev mus ncig ntau dhau yuav tsum tau zam kom tsis txhob delamination.

7. Txheej Txheej
Muaj cov dej hloov tau yooj yim -resistant putty thiab sab nrauv- qib zoo nkauj txheej. Lub putty qhov hloov pauv yog qhov tseem ceeb rau kev ua haujlwm me me yam tsis muaj kev tawg.

Cov txheej txheem reinforcement installation ua raws li peb kauj ruam meej:

• Kauj ruam ib: Siv lub hauv paus polymer- hloov kho render ntawm 2-3mm thickness, ib txhij embedding tej ntug-wrap mesh.
• Kauj Ruam Ob: Tam sim ntawd nro thiab embed lub iav fiber ntau rau hauv lub hauv paus ntub dej siv lub trowel, ua hauj lwm los ntawm qhov chaw sab nraud. Lub mesh yuav tsum tsis txhob embedded tob heev - nws kev ntxhib los mos yuav tsum nyob twj ywm pom los ntawm lub render.
• Kauj ruam peb: Ua ntej lub hauv paus render sets, siv lub tsho tiv no saum toj kawg nkaus ntawm 1-2mm thickness, tsuas yog txaus los npog lub mesh thaum tso cai rau nws cov profile kom nyob twj ywm faintly pom.

Los ntawm cov txheej txheem no - los ntawm - txheej txheej tsom xam, nws tau pom tseeb tiasiav fiber meshoccupies nruab nrab - mus rau - sab nraud ntawm cov txheej txheem reinforcement - tag nrho encapsulated los ntawm ob lub tsho tiv no nyob rau hauv "sandwich" configuration. Txoj hauj lwm no yog qhov tshwm sim ntawm kev siv hluav taws xob dav dav: qhov ntiav heev thiab cov mesh poob kev tiv thaiv; sib sib zog nqus heev thiab nws tsis tuaj yeem tswj qhov tawg ntawm qhov chaw zoo.

Qhov kev tso kawm meej no ua rau cov mesh ua haujlwm hauv kev sib koom ua ke nrog kev ua haujlwm, sib sau ua ke tiv thaiv thermal stress, cua loads, thiab kev cuam tshuam lub zog- ua rau lub sij hawm ntev - lub sij hawm durability xav tau ntawm niaj hnub tsev hnab ntawv.

Yog tias koj muaj lus nug ntxiv txog cov txheej txheem rwb thaiv tsev sab nrauv kom nthuav dav lossis xaiv cov iav fiber ntau tsim nyog rau koj qhov kev xav tau tshwj xeeb, peb pab neeg ua haujlwm tau npaj los pab.
