1. Microsilica hmoov yog ib qho nruab nrab inorganic muab tub lim nrog lub cev ruaj khov thiab tshuaj lom neeg. Nws tsis muaj cov dej siv lead ua, tsis koom nrog kev kho cov tshuaj tiv thaiv, thiab tsis cuam tshuam rau cov tshuaj tiv thaiv mechanism.
2. Nws muaj qhov zoo wettability rau ntau yam resins, zoo adsorption kev ua tau zoo, sib tov yooj yim, thiab tsis muaj agglomeration.
3. Microsilica hmoov muaj qhov tsim nyog particle loj tis, muaj zog ceev, siab hardness, thiab zoo hnav tsis kam. Nws tuaj yeem txhim kho qhov tensile, compressive, cuam tshuam lub zog thiab hnav tsis kam ntawm cov khoom kho, thiab kev puas tsuaj tuaj yeem nce ntxiv los ntawm 0.5 -2.5 npaug.
4. Nws tuaj yeem ua kom cov thermal conductivity, hloov cov nplaum thiab ua kom cov nplaim hluav taws kub ua haujlwm.
5. Nws tuaj yeem txo qis exothermic ncov kub ntawm epoxy resin curing cov tshuaj tiv thaiv, txo cov linear expansion coefficient ntawm cov khoom kho thiab cov nqi shrinkage ntawm cov khoom kho, yog li tshem tawm cov kev ntxhov siab sab hauv thiab tiv thaiv kev tawg.
6. Vim yog qhov loj me me thiab tsim nyog faib ntawm microsilica hmoov, nws tuaj yeem txo thiab tshem tawm cov nag lossis daus thiab stratification phenomena.
7. Microsilica hmoov yog ntshiab nyob rau hauv cov xwm, muaj cov ntsiab lus impurity tsawg, thiab muaj lub cev ruaj khov thiab tshuaj lom neeg, ua rau cov khoom kho tau zoo rwb thaiv tsev thiab arc tsis kam.
8. Cov tshuaj muaj pes tsawg leeg ntawm microsilica hmoov yog silicon dioxide (SiO2), uas yog ib qho inert tshuaj thiab tsis hnov tsw tshuaj nrog feem ntau cov kua qaub thiab alkali. Microsilica hmoov yog tusyees faib thiab them rau saum npoo ntawm cov khoom, thiab muaj zog corrosion kuj. Lub cavitation tsis kam yog nce los ntawm 3-16 zaug.
9. Microsilica hmoov muaj qhov ntim me me: ib qho yog nyob nruab nrab ntawm 0.2-0.8, thiab lwm qhov yog nruab nrab ntawm 1.0-2.2. Raws li cov khoom siv polymer filling, nws siv tsawg dua li lwm cov pob zeb hauv av fillers, muaj qhov hnyav me me, thiab txuag cov nyiaj polymer, yog li txo cov nqi khoom.
10. Frost tsis kam: Tom qab 300-500 ceev ceev khov thiab thawing voj voog ntawm microsilica hmoov, tus txheeb ze elastic modulus txo los ntawm 10-20%, thaum tus txheeb ze elastic modulus ntawm cov qhob zoo tib yam txo los ntawm 30-50 zaug tom qab 25-50 cycles. 73%. Yog li ntawd, Frost tsis kam ntawm pob zeb tuaj yeem txhim kho.
