Mawonekedwe

Nano-silica particles malinga ndi kapangidwe kawo amagawidwa m'mitundu iwiri: P-mtundu (Porous particles) ndi S-mtundu (Spherical particles).P-mtundu wa nano-silica pamwamba uli ndi nano-porous angapo ndi pore mlingo wa 0.611ml / g;chifukwa chake, mtundu wa P uli ndi SSA yokulirapo poyerekeza ndi mtundu wa S (Onani US3440).US3436 ndi mtundu wa S ndipo SSA yake ndi ~170-200m2/g.Kuphatikiza apo, mawonekedwe a P-mtundu wa ultraviolet ndi> 85%, S-mtundu:> 75%.

Njira Zoyesera

1. Njira yotumizira ma electron microscopy (TEM), tinthu tating'onoting'ono tating'onoting'ono, tinthu tating'onoting'ono tating'onoting'ono.
2. BET njira, nano-silica tinthu ali lalikulu enieni pamwamba m'dera.
3. Infuraredi spectroscopy njira, nano-silika tinthu alipo chiwerengero chachikulu cha magulu hydroxyl ndi unsaturated zotsalira zotsalira pamwamba pake, ndi kupanga kupatuka ku mkhalidwe wokhazikika wa silicon okusayidi dongosolo.
4. Njira yoyesera ya Cary-5E spectrophotometer, tinthu tating'onoting'ono ta nano-silica-kunyezimira kwakukulu kumafunde aatali ndi kuwala kowonekera kwa UV.
5. Omnisorp100CX pamwamba ndi porosity analyzer, P-mtundu wa nano-silica pamwamba imakhala ndi nano porous ndi pore mlingo wa 0.611ml / g.

Kugwiritsa ntchito

1 Mpira wosinthidwa, sealant ceramic toughening kusinthidwa, zomatira, zowonjezera CHIKWANGWANI, pulasitiki kusinthidwa, utoto
ukalamba zowonjezera;
2 Ceramics, nano ceramic, gulu la ceramic gawo lapansi;
3 polima: akhoza kuonjezera bata matenthedwe ndi odana ndi ukalamba polima;
4 zida zotchingira moto ndi zokutira, sing'anga yapamwamba yopera, zodzikongoletsera;
5 Mu cluster butyl benzene ndi chlorinated polyethylene kuwonjezera kachulukidwe kakang'ono ka nano SiO2 amapanga kukhazikika kwa rabala,
elongation, mphamvu, flexural performance ndi ultraviolet kukana ndi kutentha kutentha ntchito ndi kukwaniritsa kapena kupitirira epdm;
6 Pachikhalidwe ❖ kuyanika kuwonjezera pang'ono oxides nano pakachitsulo, zabwino kuthetsa kuyimitsidwa bata, thixotropy ndi osauka, osauka mapeto.
