Feem ntau xaiv unencrypted silica hmoov raws li cov khoom kub resistant. Nrog dej txo tus neeg sawv cev, ya tshauv, ntxhia hmoov, fiber ntau muaj kev sib raug zoo; vim yog kev siv qhov sib txawv filling tshwm sim, silica fume kuj muaj qhov muaj zog viscosity, yog li cov pob zeb tsis zoo sib xyaw nrog silica fume tsim qauv zoo dua qhov siab ntawm cov pob zeb zoo tib yam 2 ~ 3cm; thiab sib xyaw ntim, ntau lawm thiab ua cov pob zeb ua kom muaj zog thiab txhaj tshuaj, micro-silica fume mixing ntim ntawm cov cement ntau npaum li cas ntawm 6 ~ 12%; underwater engineering pob zeb sib xyaw ntim yog me ntsis siab dua; Thaum silica fume yog siv los ua lub twj tso kua mis, tag nrho cov tshuaj txo qis rau li 2%. Qhov piv tau lees paub los ntawm kev ntsuas piv. Kev sib xyaw ntawm silica fume nrog cov cement thiab aggregate yuav tsum tau ua raws li cov lus qhia nruj, thiab tib lub sijhawm, kev saib xyuas yuav tsum muaj zog.
Silica fume yuav tsum tau qhia tam sim ntawd tom qab casting vim nws qhov tshwj xeeb ultrafine xwm, thiab microsilica fume tsis tuaj yeem ntxiv rau pob zeb. Los yog ntxiv cov hmoov micro-silica, lub sijhawm sib xyaw yog 30-40 vib nas this ntev dua li cov pob zeb zoo tib yam, nrog rau homogeneity zoo. Tsis muaj kev tshwj xeeb rau kev thauj mus los, tib yam li cov pob zeb zoo tib yam. Tsis tas li ntawd, thaum koj siv silica fume, koj yuav tsum vibrate thiab compact, thiab koj yuav tsis nco lub vibration los yog vibrate ntau dhau.
Lub sijhawm vibration feem ntau yog 10-30 vib nas this; Kev muab cov pob zeb txuas ntxiv yog xav tau los tiv thaiv cov kab mob khaub thuas thiab cov teeb meem zais. Nws tseem yog ib qho tseem ceeb uas lub sij hawm stubbing tsis pub dhau 100 feeb los tiv thaiv cov dej evaporation ntxov ntxov. Vim li no, silica fume yog them nrog ib zaj duab xis tam sim ntawd tom qab nchuav, thiab cov hnab thiab dej tau nthuav tawm rau kev saib xyuas. Feem ntau nws yog industrial compressed microsilica hmoov, uas yuav ua tau manually cam khwb cia los yog cia li cam khwb cia.
