Glassfiber Mesh: Kev Mus Saib Xyuas Lub Chaw Haujlwm - Cov ntaub ntawv tseem ceeb dab tsi uas peb yuav tsum tsom mus rau hauv Daim Ntawv Qhia Txog Kev Xeem?

Among all test items, the alkali-resistant tensile strength retention rate is the most critical durability indicator for reinforcement mesh. It simulates the℃of strength degradation of the material after long-term service in the highly alkaline environment (pH>12.5) ntawm cement mortar.

Txoj Kev Xeem: Raws li Cov Lus Qhia Ntxiv B ntawm JGJ144-2019 lossis GB / T 20102 tus qauv, cov qauv tau muab tso rau hauv cov tshuaj alkaline tshwj xeeb rau lub sijhawm teem, tom qab ntawd lawv lub zog tensile tawg raug kuaj thiab suav ua feem pua ​​​​ntawm qhov pib lub zog.

Kev lees txais: Rau mesh siv nyob rau hauv lub rwb thaiv tsev sab nrauv, JGJ144-2019 yuav tsum muaj alkali-resistant tensile zog tuav tus nqi yuav tsum tautsis pub tsawg tshaj 80%. Qhov no txhais tau hais tias tom qab raug alkaline, cov khoom yuav tsum khaws tsawg kawg yog plaub - tsib feem pua ​​ntawm nws lub zog qub. Qhov siab dua tus nqi khaws cia, qhov kev ntseeg siab ntau dua qhov kev ua haujlwm ntev -. Lub tsev cov ntaub ntawv kev lag luam tus qauv JC/T 841-2007 teem ib tug yuav tsum tsis pub tsawg tshaj li 75%, nrog rau qhov sib txawv stemming los ntawm txawv stringency ntawm daim ntawv thov scenarios.

Peb Cov Lus Qhia: Txheeb xyuas seb tus nqi no hauv daim ntawv tshaj tawm puas siab dua lossis sib npaug li 80% (rau kev siv rwb thaiv tsev sab nrauv) thiab nco ntsoov seb tus qauv ntsuas ntsuas yog JGJ144-2019 lossis JC/T 841.

Tensile breaking lub zog txiav txim siab lub hauv paus load-cov kabmob muaj peev xwm qhov kev txhawb nqa muab rau cov txheej txheem ua haujlwm thiab yog qhov yooj yim lav rau tiv thaiv cua loads thiab thermal stress.

Txoj Kev Xeem: Kuaj raws li GB/T 7689.5 siv txoj kev sawb. Cov ntawv ceeb toom feem ntau muab qhov tseem ceeb ntawm kev sib tsoo rau ob qho tib si warp thiab weft cov lus qhia.

Kev lees txais: Txawv grammage meshes sib haum rau cov kev xav tau ntawm lub zog sib txawv. Piv txwv li, alkali-resistant mesh rau sab nrauv rwb thaiv tsev nrog ib tug grammage ntawm 160g / m² feem ntau yuav tsum tau warp thiab weft tensile tawg lub zog yuav ntau dua los yog sib npaug rau 1200N / 50mm. Cov khoom uas muaj grammage siab dua muaj cov kev xav tau ntau dua.

Peb Cov Lus Qhia: Sib piv cov nqi ntsuas hauv daim ntawv tshaj tawm nrog cov khoom nominal qhov tseem ceeb thiab paub meej tias ob qho tib si warp thiab weft cov ntaub ntawv ua tau raws li qhov yuav tsum tau ua.

Elongation ntawm kev tawg qhia txog cov khoom muaj peev xwm deform ua ntej fracturing thiab yog ib qho tseem ceeb qhia rau kev nkag siab txog nws "kev hloov pauv."

Kev lees txais: Raws li JC/T 841-2007, qhov elongation ntawm so yuav tsum tsis pub ntau tshaj 4.0%. Qhov no qhia tau hais tias xws li reinforcement mesh yog ib tug tsawg - elongation cov ntaub ntawv, tsim nyob rau hauv lub hauv paus ntsiab lus ntawm rigid reinforcement - muab high-strength txwv txwv tsis pub tawg propagation.

Peb Cov Lus Qhia: Paub meej tias qhov elongation ntawm kev tawg hauv daim ntawv tshaj tawm yog tsawg dua lossis sib npaug li 4.0%. Qhov siab elongation ntau dhau tuaj yeem qhia tias tsis txaus rigidity kom muaj txiaj ntsig zoo cuam tshuam cov substrate deformation.

Grammage yog ib qho kev xav ntawm cov ntsiab lus fiber ntau, txheej thickness, thiab weave ntom, ncaj qha txuas cov khoom ntawm cov khoom siv kho tshuab rau nws cov nqi yuav khoom.

Kev lees txais: Raws li JC/T 841-2007, tus nqi ntsuas yuav tsum nyob rau hauv ± 8% ntawm tus nqi nominal. Piv txwv li, ib yam khoom nominally 160g / m² yuav tsum muaj qhov ntsuas ntawm 147.2 thiab 172.8g / m². Kev sib txawv ntau dhau yuav qhia tau tias cov txheej txheem tsim khoom tsis ruaj khov lossis muaj kev pheej hmoo ntawm kev tsim cov grammage nrog pheej yig fillers.

Peb Cov Lus Qhia: Sib piv cov nqi ntsuas hauv daim ntawv tshaj tawm nrog cov ntawv qhia cov khoom lag luam thiab xyuas kom meej tias qhov sib txawv tau poob rau hauv qhov kev tso cai.

Rau kev txhawb nqa mesh tsim siv alkali- iav fiber ntau tiv taus, cov ntsiab lus zirconia (ZrO₂) yog cov tshuaj tseem ceeb hauv kev txiav txim siab nws qhov kev tiv thaiv alkali.

Kev lees txais: Raws li JC/T 841-2007, ZrO₂ cov ntsiab lus yuav tsum yog (14.5 ± 0.8)% ; los yog qhov sib xyaw ua ke ntawm ZrO₂ thiab TiO₂ yuav tsum Ntau dua lossis sib npaug rau 19.2%, nrog rau ZrO₂ cov ntsiab lus Ntau dua lossis sib npaug rau 13.7%. Zirconia ua raws li "txhim kho cov txheej txheem tshuaj tua kab mob," nyiam ua kom nkag mus rau hydroxyl ions, siv qhov nruab nrab hnyav thiab tiv thaiv lub cev fiber ntau.

Peb Cov Lus Qhia: Yog tias cov khoom thov siv alkali- iav fiber ntau tiv taus, daim ntawv tshaj tawm yuav tsum suav nrog cov ntaub ntawv xeem rau ZrO₂ cov ntsiab lus uas ua tau raws li cov qauv saum toj no.

Daim ntawv pov thawj kev xeem ntawv rauiav fiber meshtsis yog tsuas yog kev pom zoo ntawm cov khoom zoo tab sis kuj yog ib qho kev lees paub ntawm qhov ntev - lub sij hawm qhov kev ntseeg tau. Raws li kev txiav txim siab- cov neeg tsim khoom, peb tsis tas yuav dhau los ntawm tag nrho cov ntaub ntawv, tab sis plaub lub ntsiab lus qhia -Alkali-Resistant Tensile Strength Retention Rate (Ntau dua lossis sib npaug li 80%), Pib Tensile Breaking Strength, Elongation ntawm Break (tsawg dua lossis sib npaug li 4.0%), thiab Mass ib Cheeb Tsam (± 8%)- Tsim nyog koj ua tib zoo mloog txhua zaus koj tshuaj xyuas daim ntawv tshaj tawm.
