Uhlalutyo lweSicelo seFiber yeBasalt eqoshiweyo kwiKhonkrithi
Ukwengeza kwi imicu ye-basalt, iifayibha zekhabhoni, Ifayibha yeglasis, kunye neefayibha ze-aramid nazo zisetyenziswe njengezinto zokuqinisa kwikhonkrithi. Nangona kunjalo, indlela yokusebenza ixesha elide ibonise ukuba ezi zinto zineengxaki ezithile xa zisetyenziswa kwikhonkrithi, nto leyo eyenza kube nzima ukuhlangabezana neemfuno zemarike zekhonkrithi esebenza kakuhle. Ukuvela kwefayibha ye-basalt eqoshiweyo kuzalise esi sikhewu kuzo zombini izixhobo kunye neendlela, nto leyo ekhuthaza kakhulu uphuhliso lwetekhnoloji yokuqinisa kunye nokuqinisa ikhonkrithi. Indima yayo ekuqiniseni ikhonkrithi ibonakala kakhulu kwezi zinto zilandelayo:
1.Ukuthintela okuSebenzayo kweCrack: Iifayibha zebasalt ezinqunqiweyo, besebenzisa ubungakanani babo kunye neenzuzo zommandla womphezulu, banokuthintela ngempumelelo ii-micro-cracks kwaye bathintele ukwanda kwazo kunye nokunxibelelana kwazo. Kwangaxeshanye, boyisa iingxaki zezinye iifayibha zokwenziwa, ezinje ngoxinano oluphantsi, amandla aphantsi okutsalwa, kunye ne-low elastic modulus. Azitsalwa lula ngexesha lokusasazeka kwee-crack, nto leyo ethintela kakhulu uphuhliso lwee-micro-cracks kwaye ilibazise ukwakheka kwezintsha, nto leyo echaphazela kakuhle ukungangeni kwekhonkrithi kunye nokumelana nokuqandusela komkhenkce.
2.I-Modulus ephezulu kunye Ulwakhiwo Ukulungela: Iifayibha zebasalt ezinqunqiweyo Ayiboneleli nje kuphela ngeenzuzo ze-modulus ephezulu kunye namandla aphezulu okutsalwa kwe-single-filament, afana neefayibha zentsimbi, ukuthintela ukwanda kweentanda, kodwa ikwayoyisa ngempumelelo iingxaki zeefayibha zentsimbi, njengokuthambekela kwazo kokuqunjelwa ngexesha lokuxuba, okuthintela ukupompa nokwakha.
3.Ukusasazeka Okuhle Nokuhambelana: Njengefayibha engabonakaliyo esekwe kwi-silicate, ifayibha ye-basalt eqoshiweyo inokuhambelana kwendalo nezinto ezisekwe kwisamente. Ubuninzi bayo (malunga ne-2.63-2.80 g/cm³) bufana nobo bekhonkrithi yesamente kunye nodaka, okuqinisekisa ukusebenza kakuhle, kwaye inokusasazwa ngokulinganayo kwisakhiwo sekhonkrithi emva kokufakwa.
4.Ukuqina Okugqwesileyo: Umphezulu uguqulwe iintambo zebasalt eziqoshiweyo zibonakalisa iimpawu "zefayibha engasebenziyo", zibonisa ukumelana okugqwesileyo nobushushu obuphezulu, ukumelana nokugqwala, kunye nokumelana nempembelelo. Zigcina uzinzo nakwiindawo ezinobushushu obuphezulu nezingcolisayo kakhulu kwaye zinokuphucula ukumelana nokuguquguquka kwe-matrix yesimenti. Ke ngoko, zinokuziqhelanisa neendawo ezifuna kakhulu zokuxuba, ukuthulula, ukubeka, kunye nokusebenzisa ikhonkrithi, nto leyo ephucula kakhulu ukuqina kwekhonkrithi.
Isishwankathelo, ifayibha yebasalt eqoshiweyo inokuphucula ngempumelelo ukumelana nempembelelo yekhonkrithi, inciphise ukuqhekeka kwayo, kwaye iphucule ngokupheleleyo iimpawu zayo zoomatshini. Ngokukodwa, inokudlala indima ekuthinteleni iintanda, ukungangeni kwamanzi, ukuqina okuphuculweyo, ukuphuculwa kwempembelelo kunye nokumelana nokuxinana, kwaye inegalelo ekuphuculweni komgangatho wembonakalo kwizakhiwo zekhonkrithi.
