Suoyi 50nm Nano Silicon Oxide Sio2 Fibrous Nano-Silica White Powder Powombera Zida Zodzazitsa za Rubber/Polymer

Maonekedwe a nano silica ndi ufa woyera wa amorphous. Kukula kwa tinthu tating'onoting'ono ndi 1-100 nanometers, ma microstructures ndi ozungulira, ndipo tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono.

Kutha katundu: sangathe kusungunuka m'madzi ndi asidi (kupatula hydrofluoric acid) ndi zosungunulira organic, ndipo akhoza kusungunuka mu zamchere ndi hydrofluoric acid.

Kukhazikika: kukhazikika

Kugwiritsiridwa ntchito kwa nano silika kumagwiritsidwa ntchito kwambiri, kulemera kwake ndi 0.5 - 2%, ndipo dongosolo la mankhwala likhoza kufika kuposa 10%. Chinsinsi cha ntchito ya mankhwalawa ndikuti imabalalika kwathunthu mu dongosolo. Malinga ndi machitidwe osiyanasiyana, silika nanoparticles amamwazikana m'madzi, acetone, alcohols kapena zosungunulira zina molingana ndi machitidwe osiyanasiyana. Kwa machitidwe opangira mafuta, othandizira amatha kuwonjezeredwa kuti ayambe kuchiritsira.

Konkire ndiye chinthu chomwe chimagwiritsidwa ntchito kwambiri pomanga ndipo kapangidwe kake kamawononga pafupifupi simenti yonse padziko lonse lapansi. Kugwiritsiridwa ntchito kwa simenti yambiri kumapangitsa kuti mpweya wa CO2 ukhale wochuluka, ndipo zotsatira zake zimakhala zobiriwira. Njira yochepetsera simenti yosakanikirana ndi konkriti ndikugwiritsa ntchito chindapusa cha silika. Chimodzi mwazolipira za silika zokhala ndi kuthekera kwakukulu monga kusintha simenti komanso ngati chowonjezera cha konkire ndi nano-silica. Komabe, malonda a Nano silica amapangidwa m'njira yovuta kwambiri, zomwe zimapangitsa kuti zikhale zoyera komanso zovuta zomwe zimapangitsa kuti zisagwiritsidwe ntchito pamakampani omanga. Kuphatikiza apo, kugwiritsa ntchito silika ya Nano ndi zotsatira zake mu konkriti sikunamveke bwino.

Nano silika mu konkriti:

Nano silica (yofanana ndi SY-SP30) imatha kusintha kwambiri mawonekedwe osinthika a aggregate ndikuyika mu konkriti, ndikutsimikizira mphamvu ya nano silica (yofanana SY-SP30) pamitengo ya konkire kuchokera ku ngodya ya microcosmic. Wothandizira mpweya amatha kusintha kugwa kwa konkire koma akhoza kuchepetsa pang'ono kukula; akhoza kuchepetsa compressive mphamvu konkire pa siteji iliyonse; akhoza kuchepetsa kwambiri kudzikonda shrinkage kupsyinjika konkire; onjezerani mphamvu ya konkire yotsutsa komanso kukana kwachisanu kwa Cl-, makamaka kukana kwa chisanu ndi kulimba. Ngakhale retarder akhoza kuchepetsa oyambirira compressive mphamvu konkire, ali ndi zotsatira zochepa pa mphamvu kenako konkire.
