Uqinisekiso lweBasalt Fiber kwiZicelo zoBunjineli obuSebenzayo kunye noPhando
1.I-Basalt Fiber ukuqinisa iindlela zekhonkrithi
Iindlela zekhonkrithi eziqinisiweyo rhoqo zilawula ukuqhekeka ngenxa yokuncipha ngokubeka inani elaneleyo leebha zokuqinisa kwicala elide. Olu yilo alupheleli nje ekuphuculeni amandla okulayisha kunye nokuqina kwendlela kodwa lukwaphucula imeko yokuqhuba iimoto ngokungaboneleli ngokwandiswa kunye nokudibanisa ngexesha UlwakhiwoNangona kunjalo, ekubeni isakhiwo sendlela singenakuvalwa ngokupheleleyo, izinto ezinje ngokungena kwamanzi emvula kunye nokunyuka kweqabaka kunokukhokelela ekungcoleni kwentsimbi eqinisiweyo, nto leyo echaphazela kakhulu ubomi benkonzo yendlela.
Ifayibha yeBasalt ukuqinisa kungasetyenziswa endaweni yokuqinisa intsimbi yendabuko kwiindlela zekhonkrithi eziqinisiweyo rhoqo ngenxa yokumelana kwayo nokugqwala okugqwesileyo kunye namandla aphezulu okutsalwa. Esi sisombululo sisombulula ngempumelelo ingxaki yokugqwala kwentsimbi, ngaloo ndlela siphucula kakhulu ukuqina kwendlela yekhonkrithi. Ukongeza, ifayibha yebasalt Ukuqinisa kuxhomekeke kwizixhobo ezisebenzisa ikhabhoni ephantsi nezinobuhlobo nokusingqongileyo, kwaye inzuzo yaso yexabiso iya kuba nkulu ngakumbi xa kuncipha izixhobo zentsimbi. Izifundo ezikhoyo zibonise ukuba ukusebenzisa ukuqinisa i-BF-RP kwiindlela zekhonkrithi kubonisa iingenelo ezicacileyo ngokubhekiselele ekuqineni nasekuchaseni ukugqwala, kwaye ubunzima bokwakha kunye nenkqubela phambili ziyafana nezo zokuqinisa intsimbi. Nangona kunjalo, ngenxa yemodulus ephantsi yokuqina kokuqinisa i-BF-RP, kuyimfuneko ukwandisa kancinci umlinganiselo wayo wokuqinisa, ngesiqhelo phakathi kwe-0.78% kunye ne-1.0%, kwaye wamkele ingcamango yoyilo "yobubanzi obuncinci bokuqinisa kunye nendawo ekufutshane".
2.Uphando malunga nokuqiniswa kwefayibha ye-basalt ekuqiniseni iikholamu ezimfutshane zoxinzelelo lwekhonkrithi engaqhelekanga
Iindlela zokuqinisa zemveli zihlala zisebenzisa intsimbi ephuma ngaphandle, kodwa le ndlela inzima ekwakheni kwaye ayixhathisi kakhulu kubushushu obuphezulu kunye nokugqwala. Iimpawu ezilula, ezinamandla aphezulu, ubushushu obuphezulu kunye nokugqwala kwezinto zefayibha ze-basalt zizisa ukhetho olutsha kwinkqubo yokuqinisa. Okwangoku, itekhnoloji yokuqinisa ye-bonded ifayibha yebasalt amaphepha avuthiwe, kodwa uphando lokuphucula umthamo womthwalo we-flexural weekholamu zekhonkrithi ngokufaka imisipha ye-basalt fiber luncinci kakhulu. Uncwadi olufanelekileyo lubonisa ukuba ifayibha yebasalt Ukuqinisa kuphucula kakhulu amandla okugoba ecaleni kweekholamu zekhonkrithi kwaye kunokuphucula ngakumbi amandla okuthwala umthwalo ngokudibanisa indlela yokuthumela ngaphandle ilaphu le-basalt fiber.
Ulandelelwano lokwakhiwa kokuqiniswa kwefayibha ye-basalt efakwe ngaphakathi lulandelayo:
- Vula umjelo ngokobungakanani boyilo
- Hlamba umjelo
- Faka iarhente yokubopha (i-epoxy resin adhesive)
- Ukufaka iibha ze-BF-RP
- Gcwalisa nge-binder ngokulinganayo
- Linda ukuba i-binder iphole uze emva koko wenze unyango lomphezulu.
Ngokudibanisa nelaphu le-basalt fiber elivela ngaphandle, uqinisekiso lwe-BF-RP lunokuthintela ngempumelelo isiganeko sokutyibilika nokuqhekeka kwenkqubo yoxinzelelo, ulwakhiwo lulula kwaye lusebenza kakuhle, kwaye luthatha indawo encinci, enezibonelelo ezingenakuthelekiswa nanto.
3. Imiqadi yekhonkrithi eqinisiweyo yefayibha yeBasalt
Ukuqinisa i-BF-RP sisixhobo sokuqinisa esingeyosinyithi esinobuhlobo nokusingqongileyo, esinamandla aphezulu kwaye sineempawu ezifana nokumelana nokugqwala, ukuthintela i-electromagnetic, kunye nokumelana nokudinwa, nto leyo eyenza ukuba ibe yenye indlela ekhethwayo endaweni yokuqinisa intsimbi kwiiprojekthi ezithile ezikhethekileyo. Nangona kunjalo, ngokungafaniyo neebha zentsimbi eziqhelekileyo, iibha ze-BF-RP azinawo umgangatho obalulekileyo wokukhupha kwaye zine-modulus ephantsi yokuqina, nto leyo enokubangela ukuphambuka okukhulu kwemithamo yekhonkrithi ejongene nomthwalo ofanayo. Nangona umonakalo wekhonkrithi ngokuqinisa i-BF-RP ubuthathaka kwaye ungenaso isilumkiso esicacileyo, uvelisa ukuguquguquka okukhulu ngaphambi komonakalo, endaweni yoko unika isilumkiso sokhuseleko lwesakhiwo.
Ukuba isakhiwo sineemfuneko ezingqongqo zokuqhekeka kwekhonkrithi, kuyimfuneko ukuqwalasela ukufaka i-prestressing kwi-basalt fiber tendons, okanye ukwandisa i-modulus yazo yokuguquguquka, kunye nokuzixuba nokuzidibanisa ne-steel reinforcement ukuqinisekisa uzinzo kunye nokhuseleko lwesakhiwo.
