GRC ndi chiyani?
GFRC ndi yofanana ndi magalasi odulidwa a fiberglass (mtundu womwe umagwiritsidwa ntchito popanga ziboliboli zamabwato ndi mawonekedwe ena ovuta amitundu itatu), ngakhale ndizofooka kwambiri.Amapangidwa pophatikiza kusakaniza kwa mchenga wabwino, simenti, polima (nthawi zambiri acrylic polima), madzi, zosakaniza zina ndi magalasi osamva alkali (AR).Mapangidwe ambiri osakanikirana amapezeka pa intaneti, koma mupeza kuti onse amagawana zofanana muzosakaniza ndi kuchuluka komwe kumagwiritsidwa ntchito.
Zina mwazabwino zambiri za GFRC ndi izi:
Kutha Kupanga Mapanelo Opepuka
Ngakhale kachulukidwe kake ndi kofanana ndi konkriti, mapanelo a GFRC amatha kukhala owonda kwambiri kuposa mapanelo achikhalidwe a konkriti, kuwapangitsa kukhala opepuka.
High Compressive, Flexural and Tensile Mphamvu
Kuchuluka kwa ulusi wamagalasi kumapangitsa kuti pakhale mphamvu zolimba kwambiri pomwe ma polima apamwamba amapangitsa konkriti kukhala yosinthika komanso yolimba kusweka.Kulimbitsa koyenera pogwiritsa ntchito scrim kumawonjezera mphamvu ya zinthu ndipo ndikofunikira kwambiri pamapulojekiti omwe ming'alu yowoneka siyingaloledwe.
Ma Fibers mu GFRC- Momwe Amagwirira Ntchito
Ulusi wamagalasi omwe amagwiritsidwa ntchito mu GFRC amathandiza kupatsa mphamvu yapaderayi.Ulusi wosamva za alkali umakhala ngati mfundo yolimbikitsira kunyamula membala pomwe matrix a polima ndi konkriti amamanga ulusiwo ndikuthandizira kusamutsa katundu kuchokera ku ulusi wina kupita ku wina.Popanda ulusi GFRC sikanakhala ndi mphamvu zake ndipo ikhoza kusweka ndi kusweka.
Kusintha kwa GFRC
GFRC yamalonda imagwiritsa ntchito njira ziwiri zopangira GFRC: kupopera ndi premix.Tiyeni tiwone mwachangu zonse ziwiri komanso njira yotsika mtengo yosakanizidwa.
Utsi-Mmwamba
Njira yogwiritsira ntchito Spray-up GFRC ndi yofanana kwambiri ndi shortcrete chifukwa kusakaniza konkire yamadzimadzi kumapopera mu mafomu.Njirayi imagwiritsa ntchito mfuti yapadera yopopera kuti igwiritse ntchito konkire yamadzimadzi ndikudula ndi kupopera ulusi wagalasi wautali kuchokera ku spool mosalekeza nthawi imodzi.Kupopera mbewu mankhwalawa kumapanga GFRC yamphamvu kwambiri chifukwa cha kuchuluka kwa ulusi komanso kutalika kwa ulusi wautali, koma kugula zida kumatha kukhala kokwera mtengo kwambiri ($ 20,000 kapena kuposerapo).
Premix
Premix amasakaniza ulusi waufupi mu konkire yamadzimadzi osakaniza omwe amawathira mu nkhungu kapena kupopera.Mfuti zopoperapo za premix sizifuna choyatsira CHIKWANGWANI, komabe zitha kukhala zokwera mtengo kwambiri.Premix imakhalanso ndi mphamvu zochepa kusiyana ndi kupopera mankhwala kuyambira ulusi ndi wamfupi ndikuyikidwa mosintha mosakanikirana.
Zophatikiza
Njira imodzi yomaliza popanga GFRC ndikugwiritsa ntchito njira yosakanizidwa yomwe imagwiritsa ntchito mfuti yotsika mtengo yopaka malaya amaso ndi kusakaniza kwapamanja kapena kutsanulidwa kumbuyo.Nkhope yopyapyala (yopanda ulusi) imapopera mu nkhungu ndipo chosakaniza cham'mbuyo chimapakidwa ndi dzanja kapena kuthiridwa mofanana ngati konkire wamba.Iyi ndi njira yotsika mtengo yoyambira, koma ndikofunikira kupanga mosamalitsa kusakaniza kwa nkhope ndi kusakaniza kwa kumbuyo kuti mutsimikizire kusasinthika kofanana ndi zodzoladzola.Iyi ndi njira yomwe opanga konkriti ambiri amagwiritsa ntchito.
