Chidule cha Basalt Fiber-Reinforced Plaster Mortar

1. Makhalidwe Ofunika a Basalt Fiber

Basalt fiberimapangidwa makamaka ndi silicon oxide, aluminium oxide, ndi iron oxide, yokhala ndi silicon oxide yambiri ndi aluminiyamu okusayidi, zomwe zimapatsa phindu lalikulu pakukana kutentha ndi Chemical kukana dzimbiri. Poyerekeza ndi ulusi wagalasi, ulusi wa basalt ulibe ma oxide achitsulo owopsa, zomwe zimapangitsa kuti mankhwala azikhala okhazikika komanso olimba kwambiri m'malo owononga monga ma alkali amphamvu ndi ma asidi amphamvu.

Kulimba kwamphamvu kwa basalt fiber nthawi zambiri kumakhala kuyambira 3000 mpaka 4800 MPa, ndipo modulus yake yotanuka imakhala pakati pa 80 mpaka 110 GPa. Izi zimapangitsa kuti ikhale yamphamvu kuposa ulusi wagalasi, yokhala ndi elongation yotsika panthawi yopuma, yomwe imathandizira bwino kukana kwa ming'alu ya zida za simenti.

CHIKWANGWANI cha Basalt chimawonetsa kukana kutentha kwambiri, komwe kumasungunuka kupitirira 1400 ° C ndi kutentha kwanthawi yayitali kwautumiki mpaka 700 ° C, kupitilira kuposa ulusi wagalasi. Izi zimapangitsa kuti zikhalebe zokhazikika zakuthupi ngakhale m'madera otentha kwambiri.

Basalt fiber imakhalanso ndi kukana kwa alkali wapamwamba, kukana kwa asidi, ndi kukana kwa UV. Imatha kukhala ndi moyo wautali wautumiki m'malo ovuta monga chinyezi, kupopera mchere, ndi dzimbiri zamankhwala, kupangitsa kuti ikhale yoyenera kwambiri pazinthu zauinjiniya monga zigawo zakunja za pulasitala zomwe zimakumana ndi malo ovuta kwa nthawi yayitali.

2. Crack Resistance Mechanism of Fiber-Reinforced Mortar

Kulimbitsa kwa ulusi mumatope makamaka kumadalira kugawa kwawo kwa malo, kutalika, zomwe zili, komanso kugwirizanitsa ndi zinthu zopangira simenti. Panthawi yowumitsa matope, ming'alu yaying'ono imatha kupangika mosavuta mkati chifukwa cha zinthu monga kuchepa kwa voliyumu kuchokera ku machitidwe a hydration komanso kupsinjika kwa kutentha komwe kumachitika chifukwa cha kusintha kwa kutentha.

Ulusi umatha kulumikiza mbali zonse za ming'alu yaying'ono, zomwe zimapangitsa kuti ming'alu ikapangike, kuchedwetsa kufalikira kwa ming'alu ndikuwongolera kulimba kwa zinthuzo komanso kukana ming'alu. Basalt fiber ali akhakula pamwamba, amene amapereka amphamvu thupi interlocking ndi phala simenti. Pamene katundu wakunja agwiritsidwa ntchito pamatope, gawo lina la kupsinjika maganizo likhoza kusamutsidwa kupyolera mu ulusi kupita ku matrix ozungulira, motero kuchepetsa kupanikizika kwapadera ndikuletsa kufalikira kwina. Njira yobalalitsira kupsinjika iyi imathandizira kulimbitsa kulimba konse komanso kukana kwamphamvu kwa matope.

Panthawi yowumitsa matope, ulusi ukhoza kupanga kugawidwa mwachisawawa Kulimbitsa Mesh kapangidwe ka mkati mwa matrix, kuwongolera kukana kwa matope a deformation. Kuyika pulasitala kukakhala ndi kusintha kwa kutentha kwakunja, kuyanika kupsinjika kwa shrinkage, kapena katundu wamakina, mauna olimbikitsawa amatha kukana mapindikidwe m'malo opanikizika, zomwe zimapangitsa kuti zinthuzo zisamawonongeke kwambiri.
