Tshawb nrhiav cov txiaj ntsig ntawm silica hauv pob zeb Reinforcement
Mar 28, 2024
Lub hauv paus ntsiab lus ntawm Silica Fume hauv pob zeb.
Silica fume muaj zog pozzolanic zog. Nws cov txheej txheem ntawm kev ua haujlwm pib thaum silica fume tau muab tso rau hauv pob zeb, ua rau kev sib cuag nrog dej. Ib feem ntawm nws cov khoom zoo sai sai yaj, ua rau muaj kev daws teeb meem nplua nuj hauv SiO2 thiab pluag hauv Ca. Ib tug gel tsim ib txheej nplaum rau ntawm qhov chaw ntawm silica fume hais. Tom qab qee lub sijhawm, txheej txheej no, nplua nuj hauv SiO2 thiab cov neeg pluag hauv Ca, pib yaj thiab ua rau cov calcium hydroxide (Ca(OH) 2) uas tsim los ntawm cov cement hydration, uas ua rau tsim CSH gel.
Muaj txiaj ntsig zoo ntawm Microsilica Qhob
1.Enhanced Abrasion Resistance nyob rau hauv Hydropower thiab Water Conservancy Projects:Microsilica pob zeb tseem ceeb heev
txhim kho kev puas tsuaj
piv rau cov khoom siv xws li epoxy mortar. Nws qis coefficient ntawm linear expansion ua kom muaj kev sib raug zoo nrog lub hauv paus pob zeb, txo qhov kev pheej hmoo ntawm kev tawg thiab detachment, ua rau nws tsim nyog rau kev siv dav.
2.Kev txhim kho Crack Resistance hauv Hydraulic Engineering:Kev tawg hauv hydraulic pob zeb yog qhov kev txhawj xeeb thoob plaws, feem ntau tshwm sim los ntawm cov khoom siv dej kub. Thaum ya tshauv tuaj yeem txo cov nyhuv thermal no, nws lub zog thaum ntxov yog qis, txwv tsis pub siv. Microsilica pob zeb muab cov lus cog tseg los ntawm kev txhim kho kev sib tsoo tsis muaj kev cuam tshuam thaum ntxov lub zog.
3.Increased Impermeability thiab Chloride Resistance los tiv thaiv Reinforcement:Hauv cov dej hauv qab dej, cov tshuaj chloride nkag tuaj yeem ua rau cov hlau txuas ntxiv sai sai, ua rau cov pob zeb delamination thiab txo lub neej. Microsilica pob zeb txhim kho daim ntawv cog lus muaj zog thiab tiv thaiv cov tshuaj chloride nkag mus, ua kom muaj kev ruaj ntseg ntawm kev tsim kho hauv qab dej.
4.Rapid Repair with High Durability for Traffic and Highway Surfaces:Kev ua vaj tse ib txwm xav tau 28 hnub ua ntej txoj kev tuaj yeem rov qhib dua, thiab txawm tias cov pob zeb muaj zog thaum ntxov yuav siv sijhawm peb hnub. Microsilica pob zeb, nrog nws lub zog thaum ntxov thiab hnav tsis kam, muaj cov kev daws teeb meem zoo tshaj plaws rau kev kho sai thiab ruaj khov, tiv thaiv kev cuam tshuam tsheb thiab kev lag luam poob.
