I-Basalt Fiber
Ifayibha yeBasalt yifayibha eqhubekayo ethathwe kwi-basalt yendalo. Yilitye le-basalt kwi-1450 ℃ ~ 1500 ℃ emva kokunyibilika, ngokusebenzisa ipleyiti yokutsala nge-platinum-rhodium alloy wire drawing leaking speed-drawing eyenziwe ngefayibha eqhubekayo. Umbala wefayibha ye-basalt yendalo ecocekileyo ngokubanzi imdaka. Ifayibha yeBasalt luhlobo olutsha lwezinto zefayibha eziluhlaza ezisebenza kakuhle nezingaphiliyo, ezenziwe nge-silica, i-alumina, i-calcium oxide, i-magnesium oxide, i-iron oxide kunye ne-titanium dioxide kunye nezinye ii-oxide.Ifayibha eqhubekayo yeBasaltAyinamandla aphezulu nje kuphela, kodwa ikwanazo neempawu ezahlukeneyo ezintle ezifana nokufakelwa kombane, ukumelana nokugqwala, ukumelana nobushushu obuphezulu njl. Ukongeza, inkqubo yokuvelisa i-basalt fiber igqibe ekubeni ivelise inkunkuma encinci, ungcoliseko oluncinci kwindalo esingqongileyo, kwaye imveliso inokonakala ngokuthe ngqo kwindalo esingqongileyo emva kwenkunkuma, ngaphandle komonakalo, ngoko ke zizinto eziluhlaza ngokwenene, ezinobuhlobo nokusingqongileyo. Iifayibha eziqhubekayo zeBasalt zisetyenziswe kakhulu kwii-composites eziqiniswe yifayibha, izixhobo zokungqubana, izixhobo zokwakha iinqanawa, izixhobo zokukhusela ubushushu, ishishini leemoto, amalaphu okucoca obushushu obuphezulu, kunye namasimi okukhusela.
Iimpawu
① Izinto ezisetyenziswayo ezaneleyo
Ifayibha yeBasaltyenziwe nge-basalt ore enyibilikisiweyo netsaliweyo, kwaye i-basalt ore eMhlabeni naseNyangeni zizinto ezigciniweyo ezingakhethi cala, ngenxa yeendleko zezinto ezikrwada ziphantsi kakhulu.
② Izinto ezinobuhlobo nokusingqongileyo
I-Basalt ore yinto yendalo, akukho boron okanye ezinye ii-alkali metal oxides ezikhutshwayo ngexesha lenkqubo yemveliso, ngoko ke akukho zinto zinobungozi ezifumaneka kumsi, umoya awuyi kubangela ungcoliseko. Ngaphezu koko, imveliso ihlala ixesha elide, ngoko ke luhlobo olutsha lwezinto eziluhlaza ezisebenzayo zokukhusela okusingqongileyo ezinexabiso eliphantsi, ukusebenza okuphezulu kunye nococeko olufanelekileyo.
