Basalt Fiber Reinforcement mu Practical Engineering Applications and Research

1.Basalt Fiber kuwonjezera pamiyala ya konkriti

Mipando ya konkire yokhazikika mosalekeza imayang'anira kung'amba chifukwa cha kuchepa kwapang'onopang'ono poyika mipiringidzo yokwanira yolimbikitsira munjira yotalikirapo. Kapangidwe kameneka sikumangowonjezera kuchuluka kwa magalimoto komanso kulimba kwa misewu yayikulu komanso kumapangitsa kuti magalimoto aziyenda bwino posapereka njira zokulira komanso zopingasa panthawiyi. Zomangamanga. Komabe, popeza mapangidwe apansi sangathe kutsekedwa kwathunthu, zinthu monga kulowetsedwa kwa madzi amvula ndi chisanu chingayambitse kuwonongeka kwa chitsulo chowonjezera, chomwe chimakhudza kwambiri moyo wautumiki wa msewu waukulu.

Basalt fiber kulimbikitsanso kungagwiritsidwe ntchito m'malo mwa zitsulo zachikhalidwe zolimbikitsira mayendedwe a konkriti mosalekeza chifukwa cha kukana kwake kwa dzimbiri komanso kulimba kwamphamvu kwambiri. Njira ina yothetsera vutoli imathetsa bwino vuto la dzimbiri lachitsulo, motero kumapangitsa kukhazikika kwa miyala ya konkire. Kuphatikiza apo, basalt fiber kulimbikitsanso kumakhala kwa zida zotsika kaboni komanso zachilengedwe, ndipo phindu lake lamtengo lidzakhala lodziwika bwino pakutha kwa chuma chachitsulo. Kafukufuku amene alipo asonyeza kuti kugwiritsa ntchito BF-RP kulimbikitsa m'mipando ya konkire kumawonetsa phindu lodziwikiratu pokhudzana ndi kulimba komanso kukana kwa dzimbiri, ndipo zovuta zomanga ndi kupita patsogolo zikufanana ndi kulimbikitsa zitsulo. Komabe, chifukwa cha kuchepa kwamphamvu kwa BF-RP kulimbitsa, ndikofunikira kuti muwonjezere pang'ono kulimbitsa kwake, nthawi zambiri pakati pa 0,78% ndi 1.0%, ndikutengera lingaliro la "kulimbitsa pang'ono ndi kuyanika".

2.Kafukufuku wolimbitsa ulusi wa basalt pakulimbitsa konkriti zazifupi zazifupi

Njira zolimbikitsira zachikhalidwe nthawi zambiri zimagwiritsa ntchito zitsulo zakunja, koma njirayi ndi yovuta pomanga ndipo imakhala yosakanizidwa ndi kutentha kwambiri komanso dzimbiri. Zinthu zopepuka, zamphamvu kwambiri, zotentha kwambiri komanso zolimbana ndi dzimbiri za zinthu za basalt fiber zimabweretsa kusankha kwatsopano kwa njira yolimbikitsira. Pakali pano, teknoloji yowonjezera ya bonded basalt fiber ma sheet ndi okhwima, koma kafukufuku wowongolera kuchuluka kwa mizati ya konkire poyika minyewa ya basalt ndi yaying'ono. Mabuku ofunikira amasonyeza zimenezo basalt fiber kulimbitsa kwambiri kumapangitsanso mphamvu yopindika yopindika ya mizati ya konkriti ndipo imatha kupititsa patsogolo mphamvu yonyamula katundu pophatikiza njira yopangira nsalu za basalt.

Njira zomangirira zolimba za basalt fiber reinforcement ndi motere:

1. Tsegulani poyambira molingana ndi kukula kwake
2. Sambani poyambira
3. Ikani cholumikizira (zomatira epoxy resin)
4. Kuyika BF-RP mipiringidzo
5. Lembani ndi binder mofanana
6. Yembekezerani kuti chomangira chichiritse ndiyeno perekani chithandizo chapamwamba.

Pophatikizana ndi nsalu ya basalt yakunja, kulimbitsa kwa BF-RP kumatha kupeweratu zochitika za kutsetsereka komanso kupumira panthawi yamavuto, kumangako kumakhala kosavuta komanso kothandiza, ndipo kumatenga malo ochepa, omwe ali ndi zabwino zosayerekezeka.

3.Basalt CHIKWANGWANI analimbitsa konkire matabwa

BF-RP reinforcement ndi chilengedwe, champhamvu kwambiri chosagwiritsa ntchito chitsulo chomwe chimakhala ndi zinthu monga kukana kwa dzimbiri, kusungunula kwamagetsi, komanso kukana kutopa, ndikupangitsa kuti ikhale njira yokondeka kuposa kulimbikitsa zitsulo muma projekiti ena apadera. Komabe, mosiyana ndi mipiringidzo wamba zitsulo, BF-RP mipiringidzo alibe kwambiri zokolola mfundo ndipo otsika modulus ya elasticity, zomwe zingachititse kuti kupatuka kwambiri matabwa konkire pansi katundu yemweyo. Ngakhale kuwonongeka kwa konkire ndi BF-RP kulimbikitsana kumakhala kovuta ndipo kulibe chidziwitso chodziwikiratu, kumapanga mapindikidwe akuluakulu asanawonongeke, omwe m'malo mwake amapereka chenjezo la chitetezo cha zomangamanga.

Ngati nyumbayo ili ndi zofunikira zolimba kwambiri pakuphwanyidwa kwa konkire, ndikofunikira kulingalira kugwiritsa ntchito prestressing ku tendon ya basalt fiber, kapena kuwonjezera modulus yawo ya elasticity, ndikusakaniza ndikuwafananiza ndi zitsulo zolimbitsa thupi kuti zitsimikizire kukhazikika ndi chitetezo cha kapangidwe kake.
