Vim li cas fiberglass mesh ntxiv rau sab nraum qab ntawm marble?
1. Taw qhia txog kev ua haujlwm ntawmfiberglass mesh: Cov iav fiber ntau (lub npe lus Askiv qub: iav fiber ntau) yog ib qho kev ua haujlwm siab -kev ua haujlwm tsis muaj zog tsis muaj- cov khoom siv hlau. Nws yog fiber ntau ua los ntawm melting, extruding thiab stretching iav. Cov khoom tseem ceeb yog kev sib xyaw ntawm silicates xws li txhuas, calcium, magnesium thiab boron, thiab lwm yam khoom tuaj yeem ntxiv raws li xav tau rau kev hloov kho. Txoj kab uas hla ntawm ntau micrometers mus rau kaum micrometers. Muaj cov filaments ntev thiab luv filaments. Nws yog nkig, tab sis muaj lub zog tensile siab heev thiab tiv taus kub thiab corrosion. Nws muaj zoo suab rwb thaiv tsev thiab rwb thaiv tsev zog. Nws tuaj yeem siv los ua cov ntaub iav, thiab lwm yam, thiab siv dav hauv kev rwb thaiv tsev, suab rwb thaiv tsev thiab cov ntaub ntawv rwb thaiv tsev kub; Nws tseem tuaj yeem siv los ua cov khoom siv pob txha, thiab tuaj yeem ua ke nrog cov cob, cement thiab lwm yam ntaub ntawv los ua fiberglass, reinforced yas iav pob zeb thiab lwm yam ntaub ntawv sib xyaw, nrog rau fiber ntau optical. Cov yam ntxwv ntawm iav fiber ntau mesh: iav fiber ntau: qhov zoo yog cov rwb thaiv tsev zoo, muaj zog kub tsis kam, zoo corrosion kuj thiab siab mechanical zog, tab sis qhov tsis zoo yog tias nws yog nkig thiab tsis zoo hnav tsis kam. (1) Lub zog tensile siab thiab me elongation (3%). (2) High elastic coefficient thiab zoo rigidity. (3) Nws muaj qhov loj elongation nyob rau hauv nws cov elastic txwv thiab siab tensile lub zog, yog li absorbing ib tug loj npaum li cas ntawm lub zog. (4) Nws yog ib qho inorganic fiber, tsis yog -flammable, thiab muaj tshuaj tiv thaiv zoo. (5) Nws muaj qhov nqus dej tsawg. (6) Nws muaj qhov zoo ntawm qhov ruaj khov thiab kub tsis kam. (7) Nws muaj cov txheej txheem ua tau zoo thiab tuaj yeem ua rau cov khoom sib txawv xws li cov hlua, cov pob, cov ntaub, thiab cov ntaub. (8) Nws yog pheej yig. (9) Nws tsis yooj yim hlawv thiab tuaj yeem yaj rau hauv iav -zoo li hlaws dai ntawm qhov kub thiab txias.
2. Kev faib tawm ntawm iav Fiber Mesh
(1) Cov iav fiber ntau monofilaments yog cylindrical, yog li lawv cov thickness tuaj yeem qhia los ntawm lawv txoj kab uas hla. Feem ntau, raws li txoj kab uas hla, kos iav fibers tau muab faib ua ntau hom (lawv txoj kab uas hla qhov tseem ceeb yog nyob rau hauv μm): Coarse fiber: nws txoj kab uas hla monofilament feem ntau yog 30 μm; Thawj fiber ntau: nws txoj kab uas hla ntawm monofilament yog ntau dua 20 μm; Intermediate fiber: nws txoj kab uas hla monofilament yog 10-20 μm; High-qib fiber ntau: (tseem hu ua textile fiber) nws txoj kab uas hla ntawm monofilament yog 3-10 μm. Cov iav fibers nrog ib txoj kab uas hla monofilament tsawg dua 4 μm kuj hu ua ultrafine fibers. Cov kab sib txawv monofilament tsis tsuas yog cuam tshuam rau kev ua haujlwm fiber ntau tab sis kuj muaj cov txheej txheem tsim khoom, tawm los, thiab nqi. Feem ntau, 5-10µm fibers yog siv nyob rau hauv textiles, thaum 10-14µm fibers yog ntau haum rau untwisted rovings, nonwoven fabrics, thiab tws strand mats.
(2) Kev faib tawm los ntawm iav Fiber Cov yam ntxwv: Qhov no yog ib hom tshiab ntawm iav fiber ntau tsim los ua kom tau raws li cov ntawv thov tshwj xeeb. Cov fibers no muaj qee yam tshwj xeeb thiab zoo tshaj plaws thiab tuaj yeem faib dav raws li: siab -lub zog iav fiber ntau; siab -modulus iav fiber ntau; siab -kub resistant iav fiber ntau; alkali-resistant iav fiber ntau; acid-resistant iav fiber ntau; zoo tib yam iav fiber ntau (xa mus rau alkali-dawb thiab nruab nrab-alkali iav fiber); optical fiber ntau; tsawg dielectric tas li iav fiber ntau; conductive fiber, thiab lwm yam.
(3) Kev faib tawm los ntawm iav Raw Material Composition: Alkali-dawb fiber ntau (feem ntau hu ua E- iav): R2O cov ntsiab lus tsawg dua 0.8%, thiab nws yog aluminoborosilicate tivthaiv. Nws muaj kev ruaj ntseg zoo heev, hluav taws xob rwb thaiv tsev, thiab lub zog. High-alkali fiber ntau: iav tivthaiv nrog R2O cov ntsiab lus sib npaug los yog ntau dua 15%.
(4) Kev faib tawm los ntawm Mesh Loj thiab Nyhav: Raws li qhov hnyav ib square meter ntawm fiberglass mesh, nws tau muab faib ua lub teeb - hnyav thiab hnyav - hnyav fiberglass meshes. 1) Mesh cheeb tsam: 10mm × 10mm, 8mm × 8mm, 7mm × 7mm, 5mm 3 × 5mm, 4mm square, meter: nruab nrab ntawm 30 grams thiab 160 grams.
3. Mechanical Analysis of Fiberglass Mesh Reinforcement: Cov ntaub fiberglass sib txawv no muaj cov khoom siv sib txawv, thiab qhov sib txawv yog qhov tseem ceeb. Hauv kev siv tiag tiag, qhov tsim nyog fiberglass mesh yuav tsum raug xaiv raws li qhov xwm txheej ntawm cov kab nrib pleb ntawm pob zeb nto.
Kev xaiv cov txheej txheem rau marble fiberglass mesh: Rau marble nrog ntau cov kab nrib pleb, kev puas tsuaj loj, thiab tsis muaj zog, fiberglass mesh nrog mesh mesh qhib thiab kuj tuab warp thiab weft threads yuav tsum tau xaiv kom muaj zog ntawm marble nrog cov kab nrib pleb thiab kev puas tsuaj loj. Txawm li cas los xij, tam sim no, cov tuam txhab ua lag luam pob zeb tsis xaiv cov fiberglass mesh raws li txoj cai no, tab sis siv tib hom fiberglass mesh tsis hais txog ntawm cov kab nrib pleb lossis kev puas tsuaj ntawm pob zeb nto. Qhov no yog ib qho kev xyaum tsis raug.
4. Fiberglass Mesh Reinforcement Operation: Cov txheej txheem ua haujlwm rau pob zeb ntxiv nrog fiberglass mesh yog raws li hauv qab no: Ntxuav lub slab nto → Qhuav lub slab nto (kiln drying) → Mesh xaiv → Tso lub mesh → Txiav lub mesh → Sib tov cov nplaum → Siv cov nplaum nplaum → Curing . Nyob rau hauv cov txheej txheem no, ziab ntawm slab nto, xaiv thiab tso cov mesh yog qhov tseem ceeb tshaj plaws. Yog hais tias lub slab nto tsis qhuav kom zoo, los yog muaj cov dej noo los yog cov dej noo siab, nws yuav cuam tshuam rau lub zog ntawm cov nplaum, yog li cuam tshuam rau qhov adhesion ntawm lub mesh thiab cov slab, thiab tiv thaiv cov mesh los ntawm kev ua tiav nws cov nyhuv reinforcing. Kev xaiv mesh yuav tsum ua raws li qhov xwm txheej ntawm cov kab nrib pleb ntawm lub pob zeb nto; cov ntaub ntawv tsim nyog thiab kev siv yog qhov tseem ceeb rau kev txhim kho zoo ntawm fiberglass mesh. Lub mesh yuav tsum tau pw tiaj tus thiab tsis muaj bulges.
5. Daim ntawv thov Scope ntawm Fiberglass Mesh: Fiberglass mesh yog tsuas yog siv los txhawb lub nraub qaum ntawm marble slabs; txhawb nqa rov qab ntawm mosaic thiab inlaid khoom; txhawb nqa lub nraub qaum ntawm sab nrauv phab ntsa pob zeb; thiab txhawb nqa cov nplaum tsis muaj dej- pob zeb rov qab.
6. Qhov zoo ntawm Fiberglass Mesh Reinforcement: (1) Qhov saum npoo ntawm fiberglass mesh yog tiaj; (2) Cov nplaum npog tag nrho cov fiberglass mesh, thiab cov nplaum rau ntawm qhov chaw ntawm fiberglass mesh yog ib yam, tsis muaj kev sib txuam lossis cov nplaum nplaum; (3) Lub fiberglass mesh yog txiav ncaj; (4) Lub fiberglass mesh yog ruaj khov rau lub pob zeb, muaj zog adhesion. Txhim kho cov pob zeb tawg nrog fiberglass mesh tuaj yeem txhim kho lub zog ntawm marble, txo qhov tawg ntawm lub pob zeb, thiab yog li txhim kho qhov kev siv ntawm marble. Nyob rau tib lub sijhawm, nws tseem tuaj yeem txo qhov kev tawg thiab kev puas tsuaj thaum lub sijhawm tsim khoom, ua haujlwm, tuav, kev thauj mus los, thiab kev tsim kho ntawm marble, ua kom muaj kev ntseeg siab thiab zoo ntawm marble.
