Lub luag hauj lwm thiab cov ntsiab lus tseem ceeb ntawm kev tsim daim ntawv thov ntawm Alkali -resistant Fiberglass Mesh nyob rau sab nrauv phab ntsa rwb thaiv tsev System

Sab nrauv phab ntsa rwb thaiv tsev yog ib qho tseem ceeb ntawm lub tsev txuag hluav taws xob thiab kev tiv thaiv phab ntsa. Cov kab nrib pleb- tiv thaiv plaster txheej, raws li txoj kab tseem ceeb ntawm kev tiv thaiv hauv cov txheej txheem rwb thaiv tsev, ncaj qha txiav txim siab seb puas muaj teeb meem zoo xws li hollowing, tawg, thiab dej seepage yuav tshwm sim nyob rau hauv sab nrauv phab ntsa tom qab. Alkali- tiv tausfiberglass meshyog ib qho tseem ceeb ntawm cov khoom siv ntxiv rau hauv qhov tawg - tiv thaiv txheej tiv thaiv, tso siab rau nws cov tensile zoo heev thiab tawg -cov khoom tiv thaiv kom ntseeg tau ntev - lub sijhawm ua haujlwm ruaj khov ntawm cov kab hluav taws xob sab nraud.

 

I. Kev txhais lus ntawm Cov Qauv Txuj Ci Hauv Tebchaws

 

Kuv lub teb chaws tau tshaj tawm ob txoj kev lag luam tseem ceeb rau fiberglass mesh rau sab nrauv phab ntsa rwb thaiv tsev. Cov kev cai ntawm ob tus qauv sib txawv heev. Thaum xaiv cov khoom siv rau ib qhov project, tus qauv tsim nyog yuav tsum tau paub qhov txawv, thiab hom tsim nyog yuav tsum raug xaiv raws li qhov xav tau.

 

Raws li JG149-2003 "Expanded Polystyrene Board Thin Plaster Sab Nraud Phab Ntsa Rwb Thaiv Tsev": Lub alkali-resistant tensile breaking zog ntawm fiberglass mesh nyob rau hauv ob qho tib si warp thiab weft cov lus qhia yuav tsum tsis txhob tsawg tshaj li 750N / 50mm, lub alkali-resistant tensile tus nqi yuav tsum tsis pub tsawg tshaj li 5 square meters. yuav tsum ntau tshaj los yog sib npaug rau 130g.

 

Raws li JG158-2004 "Sab nrauv phab ntsa rwb thaiv tsev nrog Adhesive Powdered Polystyrene Granules": cov alkali-resistant tensile breaking zog ntawm fiberglass mesh nyob rau hauv ob qho tib si warp thiab weft cov lus qhia yuav tsum tsis txhob tsawg tshaj li 1250 N / 50 mm, lub alkali rhiab heev npaum li cas ntawm 9%. ib square meter yuav tsum ntau tshaj los yog sib npaug rau 160 g.

 

Nyob rau hauv sib piv, feem ntau sab nrauv phab ntsa rwb thaiv tsev mesh fabrics tam sim no circulating nyob rau hauv lub tsev cov ntaub ntawv lag luam muaj ib tug cheeb tsam ntawm ib ncig ntawm 160 g / ㎡, tab sis lawv cov neeg kho tshuab lub zog yog feem ntau tsis tshua muaj, nrog ib tug ib txwm tawg lub zog ntawm tsuas yog 1000 N / 50 mm los yog txawm qis dua, ua rau muaj kev pheej hmoo ntawm substandard khoom specifications. Yog li ntawd, nyob rau hauv sab nrauv phab ntsa rwb thaiv tsev tej yaam num, technical parameters ntawm lub mesh ntaub yuav tsum standardized thiab tswj. Tom qab cov ntaub ntawv tuaj txog ntawm qhov chaw thiab ua ntej kev tsim kho, cov khoom siv alkali yuav tsum tau raug tshuaj xyuas los ntawm cov khoom siv fiberglass mesh los xyuas kom ntseeg tau tias tag nrho cov ntsuas kev ua tau zoo tsim nyog ua ntej yuav siv tau.

 

Tiv thaiv cov phab ntsa sab nrauv yog ib txoj haujlwm zoo. Tsis tsuas yog cov ntaub ntawv rwb thaiv tsev yuav tsum muaj lub zog tensile tsim nyog thiab qhov kawg elongation, tab sis sab nrauv tawg - tiv thaiv txheej kuj xav tau lub zog tensile txaus raws li kev lees paub. Qhov no txhais tau hais tias thaum yuav alkali-cov fiberglass resistant fiberglass mesh, tensile zog thiab alkali tuav tus nqi yuav tsum yog ob tug tseem ceeb ntsuas uas yuav tsum tau ua tib zoo xyuas; qhov hnyav ib leeg tsis tuaj yeem tsis quav ntsej thaum cov khoom siv kho tshuab raug suav nrog.

 

II. Crack-Resistant Mechanism ntawm Alkali-Resistant Fiberglass Mesh

 

Embedding alkali-resistant fiberglass mesh rau hauv plastering mortar tuaj yeem txhim kho cov txheej txheem tiv thaiv zoo hauv ob qhov ntev.

 

Ua ntej, nws ua tau zoo ua kom tag nrho lub zog tensile ntawm plastering tiv thaiv txheej, them nyiaj rau qhov tsis muaj zog ntawm cement mortar hauv tensile lub zog.

 

Qhov thib ob, lub mesh tuaj yeem sib cais cov kev ntxhov siab sab hauv tsim nyob rau hauv phab ntsa, rhuav tshem cov kab nrib pleb uas nquag tshwm hauv phab ntsa mus rau ntau qhov zoo, tsis muaj kev puas tsuaj, yog li inhibiting tawg propagation thiab ua tiav cov kab nrib pleb hauv phab ntsa.

 

Qhov ntev - lub sij hawm alkali tsis kam ntawm lub mesh yog txiav txim los ntawm ob yam tseem ceeb. Hom fiberglass substrate yog qhov tseem ceeb ntawm kev txiav txim siab ntev -lub sij hawm alkali tsis kam thiab kav ntev; cov ntaub ntawv txheej ntawm qhov chaw ntawm lub mesh thiab tus nqi ntawm sizing thov ua lub luag haujlwm tseem ceeb hauv luv luv -lub sij hawm alkali tsis kam ntawm fiberglass mesh. Ob leeg yog indispensable. Tsuas yog nrog cov txheej txheem tsim nyog thiab cov txheej txheem tsim nyog tuaj yeem ua cov ntaub npuag tuav nws lub zog nyob rau hauv ib puag ncig alkaline mortar thiab zam cov hmoov nplej ua ntej thiab tsis ua haujlwm.

 

III. Cov ntsiab lus tseem ceeb ntawm Ntawm -site Kev Tsim Kho thiab Txheej Tshuab

 

Cov txheej txheem tsim kho kom raug yog qhov tseem ceeb heev rau cov ntaub mesh kom ua tiav nws cov kab nrib pleb -cov nyhuv tiv thaiv. Cov kev cai ua haujlwm hauv qab no yuav tsum tau ua raws li lub sijhawm ntawm - kev tsim kho qhov chaw:

Overlap dav:

Kab rov tav sib tshooj dav ntawm mesh fabrics yuav tsum tsis txhob tsawg tshaj li 100 hli; ntawm cov ces kaum sab hauv, cov ntaub mesh yuav tsum sib tshooj nrog ntau dua lossis sib npaug ntawm 100mm sib tshooj dav; ntawm cov ces kaum sab nraud, qhov sib tshooj dav yuav tsum tsis pub tsawg tshaj 100mm kom ntseeg tau tias qhov txuas ntxiv ntawm cov ces kaum.

 

Laying Quality:

Cov ntaub mesh yuav tsum tau pw ncaj, tsis muaj wrinkles los yog curling npoo; mortar fullness yuav tsum ncav cuag 100%. Tom qab kev tsim kho, nws yuav tsum tau smoothed thiab straightened tam sim ntawd los xyuas kom meej tias lub sab hauv thiab sab nraud ces kaum ntawm phab ntsa yog square thiab lub verticality raws li specifications.

 

Thawj Pem Teb Txhim Kho:

Nws raug nquahu kom siv 240g ob - txheej mesh npuag los txhawb cov phab ntsa sab nrauv ntawm thawj pem teb ntawm lub tsev kom txhim kho qhov cuam tshuam thiab tawg tsis kam ntawm phab ntsa hauv qab.

 

Diagonal Reinforcement of Openings: Ntawm plaub fab ntawm lub qhov rooj thiab qhov rais qhib, ntxiv 45℃kab pheeb ces kaum reinforcing mesh kom faib kev ntxhov siab ntawm cov ces kaum thiab tiv thaiv herringbone tawg.

 

Fireproof Barrier Overlap: Qhov sib tshooj ntev ntawm qhov thaiv qhov thaiv hluav taws xob thiab cov phab ntsa loj mesh yuav tsum muaj ntau dua lossis sib npaug li 100 hli kom ntseeg tau tias kev ruaj ntseg ntawm cov rwb thaiv tsev.

 

Kev kho mob sib tshooj

Ntawm qhov kev txiav tawm ntawm cov txheej txheem rwb thaiv tsev, qhov sib tshooj loj ntawm cov alkali -cov ntaub ntawv tiv thaiv yuav tsum tsis pub tsawg tshaj 100mm kom ntseeg tau tias qhov kawg sealing thiab txo qhov kev pheej hmoo ntawm ntug tawg thiab dej seepage.

 

Xaus

Txawm hais tias alkali-resistant fiberglass mesh tsuas yog ib qho khoom siv hauv cov txheej txheem sab nrauv phab ntsa, nws ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev tawg. Thaum lub sijhawm ua haujlwm, nws yog ib qho tseem ceeb uas yuav tsum nruj me ntsis tswj cov khoom ntawm cov khoom tuaj, txheeb xyuas qhov hnyav, lub zog tensile, thiab alkali tiv thaiv tus nqi tiv thaiv cov qauv; thiab nruj me ntsis siv cov ntsiab lus kev tsim kho xws li kev sib tshooj, kev txhawb nqa mesh, thiab sib tshooj. Tsuas yog los ntawm kev ua raws li cov qauv siv thiab ua raws li cov qauv kev tsim kho tuaj yeem ua rau muaj kev pheej hmoo ntawm sab nrauv phab ntsa tawg yuav raug txo los ntawm qhov chaw, kev pab cuam lub neej ntawm sab nrauv phab ntsa rwb thaiv tsev project yuav txuas ntxiv, thiab ntev - lub sij hawm ruaj khov kev txuag hluav taws xob hauv cov tsev yuav ua tiav.
