I-basalt fiber eqoshiwe i-fiber ye-mineral fiber kunye nobude obungaphantsi kwe-50mm enqunyulwe kwisiseko se-basalt fiber ehambelanayo kwaye inokusasazwa ngokufanayo kwikhonkrithi. Ngokutsho kokusetyenziswa kwayo, inokwahlulwa ibe ikhonkrithiifayibha enganyangekiyo(BF), i-fiber yokuqinisa i-toughening (BZ) kunye ne-fiber enganyangekiyo yodaka (BSF).
Ikhonkrithi ye-basalt enqunyulweyo ye-basalt ikakhulu ukongeza imicu ye-basalt enqunqiweyo eqhubekayo okanye engapheliyo kwikhonkrithi kwisixa esifanelekileyo, kwaye ngendlela efanelekileyo, ukuphucula ukuqina kunye nokuqina kokuqina kwekhonkrithi, ngelixa ugcina amandla oqobo oxinzelelo lwesakhiwo sekhonkrithi. amandla, ukwenzela ukomeleza ikhonkrithi kunye nokwandisa ubomi benkonzo yeprojekthi
Ukubonakala kwefayibha ye-basalt egayiweyo igcwalisa isithuba ngokwezinto eziphathekayo kunye neendlela, kwaye idlala indima enkulu ekukhuthazeni ukuqinisa kunye nokuqinisa.ukuqiniswa kwekhonkrithi . Indima yayo ekuqiniseni nasekuqiniseni okubambekayo kubonakaliswa kule miba ilandelayo:
(1) Iintambo ze-basalt ezichongiweyo zingasebenzisa ngokupheleleyo indawo yazo kunye neenzuzo zobuninzi, ukwenzela ukuba zithintele i-micro-cracks ukwenza ukuba zikhutshwe, kwaye iziphumo ziyamangalisa. Kwangaxeshanye, iyoyisa iintsilelo zezinye iintsinga zokwenziwa ezifana noxinaniso oluphantsi, amandla aphantsi okuqina kunye nemodyuli elastiki, njengokutsalwa ngokulula xa iintanda zanda, ezinokuthi zithintele ngokufanelekileyo ukwandiswa kweentanda ezincinci ezikhoyo kunye nokubonakala kweentanda. iintanda ezintsha. Ukunyibilika, ukunganyibiliki kudlale isiphumo esithile.
(2) Ukongeza kwifayibha yentsimbi, ifayibha ye-basalt enqunqiweyo inokuthatha ithuba lemodulus yayo ephezulu kunye namandla aphakamileyo okubamba ukuthintela ukwanda kweentanda, kwaye inokuthintela imicu yentsimbi ekubeni iqhinwe ngokulula ngexesha lokuzalisa. ayihambisani nempompo. ukuhanjiswa, inkqubo yokwakha inzima.
(3) I-basalt fiber echotshiweyo yi-nitrocellulose eqhelekileyo, ehambelana nendalo, kwaye ngenxa yokuba ifana nokuxinana kwikhonkrithi yesamente kunye nodaka, ubuninzi buphakathi kwe-2.63-2.8g / m³; ukusebenza kakuhle, i-basalt fibers eqoshiwe ingahanjiswa ngokulinganayo emva kokuba ifakwe kwisakhiwo sekhonkrithi.
(4) Umphezulu we-basalt fiber oqoshiwe utshintshiwe, kwaye luhlobo lwe "fiber inert", enokumelana nokushisa okuphezulu okuphezulu, ukuxhathisa kwe-corrosion kunye nokuchasana kwempembelelo. Inokugcina uzinzo kwiqondo lokushisa eliphezulu kunye nemekobume ephezulu eyingozi, kwaye inokuphucula ukuxhathisa kwe-deformation ye-matrix ye-samente. Ngako oko, i-basalt fiber eqoshiwe iyakwazi ukulungelelanisa imeko enzima kuzo zonke izigaba zokuxuba ikhonkrithi, ukuthululela, ukudibanisa kunye nokusetyenziswa, kunye nokuphucula ukuqina kwekhonkrithi.
