Kev Siv Tshuab Kev Tshawb Fawb ntawm Basalt Fiber-Reinforced Plaster Morta
1. Kev tsim kho kom zoo
(1) Mortar Mixing Optimization
Kev faib tawm tsis sib xws thaum lub sijhawm sib xyaw ua ke tuaj yeem ua rau thaj chaw muaj zog ntawm cov tshuaj khib, cuam tshuam rau nws qhov kev sib tsoo. Txhawm rau txhim kho fiber ntau dispersion, Cov khoom siv sib xyaw ua haujlwm zoo yuav tsum tau siv, thiab cov sib tov lub sij hawm thiab ceev yuav tsum tau kho kom haum los xyuas kom meej cov fiber ntau faib thoob plaws hauv lub mortar. Lub sij hawm sib xyaw kom zoo yuav pab xyuas kom cov fibers tag nrho nrog cov khoom siv cement; ob qho tib si ntev ntev los yog luv sib tov lub sij hawm yuav cuam tshuam fiber ntau dispersion thiab tag nrho cov kev ua tau zoo ntawm cov mortar. Nws yog feem ntau pom zoo rau tswj lub sijhawm sib tov rau 3-5 feeb, tsis txhob sib tov ntau dhau, uas tuaj yeem ua rau fiber ntau tawg thiab ua rau tsis zoo rau cov nyhuv reinforcing.
(2) Mortar Application Optimization
Kev siv cov txheej txheej uas nyias dhau tuaj yeem ua rau tawg, thaum txheej txheej tuab dhau tuaj yeem ua rau lub ntsej muag tsis sib xws, txo qis kev zoo nkauj thiab ua haujlwm ntev. Nws raug pom zoo rau tswj daim ntawv thov txheej thickness ntawm 3-5 mm thiab siv cov cuab yeej xws li spatulas thiab trowels los xyuas kom meej lub tiaj tiaj thiab tsis sib xws. Thaum thov, a cross-application method yuav tsum tau siv los xyuas kom meej cov fibers tag nrho npog ntawm lub mortar nto thiab ua tiav kev sib raug zoo. Zam Kev tsim kho nyob rau hauv high-kub thiab muaj zog-cua puag ncig kom txo qhov tawg los ntawm kev ziab sai heev.
(3) Txoj kev kho kom zoo
Kev ntub dej tuaj yeem tiv thaiv kom tsis txhob ya raws thaum lub sij hawm cement hydration, txo cov kab nrib pleb. Thaum lub sij hawm curing txheej txheem, tsis tu ncua txau dej kom cov mortar nto moist thiab tsis txhob raug ncaj qha mus rau lub hnub muaj zog thiab kub kub. Txhawm rau kom ntseeg tau lub zog thiab tawg tsis kam ntawm lub mortar, lub Lub sijhawm kho yuav tsum tau ncua ntev li 7-14 hnub, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas tsis muaj qhov kub thiab txias uas lub sij hawm kho tuaj yeem ua kom ntev. Thaum lub sij hawm curing, zam kev vibrations sab nraud lossis lwm yam uas yuav ua rau lub mortar puas.
2. Kev ntsuas rau Optimizing Fiber Dispersion
Ua ntej ntxiv basalt fibers, cov fibers tuaj yeem raug kho saum npoo, xws li immersion, txheej, los yog electrospinning, los txhim kho lawv affinity nrog cement-based cov ntaub ntawv, yog li pab txhawb fiber ntau dispersion nyob rau hauv mortar. Cov xaiv ntawm fiber ntau ntev thiab cov ntsiab lus ncaj qha cuam tshuam rau lawv cov dispersion thiab txhawb zog. Cov fibers ntev dua yuav entangle thaum sib tov, ua rau tsis sib xws, yog li qhov tsim nyog fiber ntau ntev thiab cov ntsiab lus yuav tsum tau txiav txim siab raws li cov txiaj ntsig kev xeem. Fiber dispersants tuaj yeem muab ntxiv rau hauv mortar los pab fiber ntau dispersion; dispersants txo cov kev sib nrig sib sib zog quab yuam ntawm fibers, cia lawv yuav tsum tau ntau uniformly faib nyob rau hauv lub mortar. Optimizing sib tov khoom thiab txoj kev, xws li kev siv cov khoom sib xyaw ua haujlwm siab lossis kev sib xyaw ua ntu zus, tuaj yeem txhim kho fiber ntau dispersion.
