2021 Ma Microspheres Abwino a Sio2 - Mikanda Yowunikira Magalasi Yopangira Zizindikiro za Msewu - Kehui

Mikanda yagalasi ndi mtundu watsopano wa zinthu zomwe zapangidwa m'zaka zaposachedwa zomwe zimagwiritsidwa ntchito mosiyanasiyana komanso zinthu zapadera. Chogulitsachi chimapangidwa ndi zinthu zopangira borosilicate kudzera muukadaulo wapamwamba, chokhala ndi tinthu tating'onoting'ono ta ma microns 10-250 komanso makulidwe a khoma la ma microns 1-2. Chogulitsachi chili ndi ubwino wolemera pang'ono, kutentha kochepa, mphamvu yayikulu, kukhazikika kwa mankhwala, ndi zina zotero. Pamwamba pake pakonzedwa mwapadera kuti pakhale mafuta ochulukirapo komanso osagwirizana ndi madzi, ndipo n'zosavuta kufalikira m'zinthu zachilengedwe.
Mikanda yagalasi yaying'ono imagwiritsidwa ntchito pochotsa dzimbiri pamakina oyendetsa ndege, malo odutsa zebra, mizere yosaima, mizere iwiri yachikasu usiku pamisewu yamagalimoto, ndi zida zowunikira usiku pazizindikiro zamagalimoto.

Chizindikiro cha zosakaniza
1. Kapangidwe ka mankhwala:
SiO2 >67%, CaO>8.0% MgO>2.5%, Na2O0.15, ena 2.0%.
2. Mphamvu yokoka yeniyeni: 2.4-2.6g/cm³.
Mawonekedwe: galasi losalala, lozungulira, lowonekera bwino lopanda zonyansa
Chiŵerengero chozungulira: ≥85% kapena kuposerapo.
3. Tinthu ta maginito sitiyenera kupitirira 0.1% ya kulemera kwa chinthucho.
4. Kuchuluka kwa thovu mu mikanda yagalasi ndi kochepera 10%.
5. Mulibe zosakaniza zilizonse za silicone resin.
6. Kuchuluka kwa zinthu: 1.5g/cm³
7. Kuuma kwa Mohs: 6-7
8. Kuuma kwa Rockwell: 48-52HRC

Mikanda yagalasi ili ndi ntchito zosiyanasiyana komanso zinthu zapadera. Ili ndi mainchesi ochepa kwambiri, kulemera kopepuka komanso mphamvu zambiri. Kuiyika pa zokutira kungapangitse kuti ikhale zokutira zowunikira zomwe anthu amafunikira. Kuwunikira kwamphamvu kwa retro-reflection, kwakukulu, kuwala kumatha kuwonekera mwachindunji ku gwero la kuwala, kotero kumapanga mphamvu yamphamvu ya retro-reflection. Kugwiritsa ntchito mikanda yagalasi yowunikira kwasintha kwambiri magwiridwe antchito achitetezo pamsewu.

Utoto wowonjezeredwa ndi mikanda yagalasi yowunikira msewu sufunikira magetsi, ndipo ukhozanso kumaliza ntchito yokumbutsa zizindikiro za usiku. Chifukwa chake, mikanda yagalasi yowunikira msewu imagwiritsidwa ntchito pazizindikiro za magalimoto, malo akunja, zizindikiro za pamsewu ndi machenjezo ena ausiku. Chiwerengero chonse cha zizindikirocho chathandiza kwambiri kuzindikira zizindikiro izi usiku, chachita bwino kwambiri potsogolera ndi kuchenjeza, ndipo chapereka mzere wolimba wachitetezo kwa oyendetsa magalimoto omwe amayendetsa usiku.

Ubwino wa mikanda yagalasi yowunikira msewu:

Zipangizo zowunikira zagalasi zazing'ono zimawonjezeredwa mwachindunji ku kapisozi ka madzi, kenako nkusinthidwa mofanana. Ngati kuli koyenera, zowonjezera zina zitha kuwonjezeredwa kuti ziwonjezere kulimba kwake, kenako zitha kugwiritsidwa ntchito mwachindunji. Ziwonjezereni mwachindunji mu slurry yowonekera, sakanizani mofanana, ndikuwonjezera zowonjezera zina malinga ndi zosowa zenizeni kuti zigwiritsidwe ntchito bwino.

Mikanda yagalasi yowunikira msewu ikhoza kuwonjezeredwa mwachindunji ku inki kuti ipange inki yowunikira, yomwe imatha kusindikizidwa pazenera kapena kupakidwa utoto pa nsalu kapena zinthu zina. Ndi yosavuta kugwiritsa ntchito komanso yosavuta kuyigwiritsa ntchito. Dziwani kuti mikanda yagalasi yowunikira Kuchuluka kwa mikanda yowonjezeredwa kumatha kuwonjezeredwa moyenera malinga ndi mulingo wofunikira wa kuwunikira.

Thirani kaye maziko owunikira, kenako dikirani mpaka maziko owunikira aume musanapopere topcoat yowunikira. Ngati pamwamba pa simenti pamangidwa, ndibwino kupopera mobwerezabwereza magawo awiri. Mukapopera, ndi bwino kugwiritsa ntchito akatswiri. Nthawi yomweyo, mukapopera, yesani malo ang'onoang'ono pasadakhale, samalani ndi nyengo yomanga, yesetsani kuti musamange nthawi yamvula, kuti musapangitse kuti magalasi owunikira a microbeads asagwire ntchito mokwanira.
