Ilaphu elingalukwanga le-basalt fiber lilaphu elenziwe ngokubeka ii-basalt fibers ezinqunqiweyo okanye ii-filaments eziqhubekayo kwi-web, emva koko ziqiniswe ngeenkqubo ezingalukwanga ezifana nokubhoboza ngeenaliti, ukufakelwa kwamanzi, kunye nokunyibilikisa (okufuna ukongezwa kwenani elincinci lee-hot-melt fibers). Ixabiso lalo eliphambili likwi "ulawulo lwayo lwesakhiwo" kunye "nokuguquguquka kokusebenza." Ngokulungisa ubude be-fiber, indlela yokubeka i-web, kunye nenkqubo yokuqinisa, iipropati zayo zomzimba nezekhemikhali zinokwenziwa ngokwezifiso ukuze zilungele iimeko ezahlukeneyo.

Ifayibha yeBasalt engajijwanga Ilaphu lilaphu elincinci elilukiweyo ngeefayibha zefayibha zebasalt eziqhubekayo (ezingajijwanga okanye ezijijwanga kancinci) kusetyenziswa izakhiwo ezilula zokuluka ezifana ne-plain kunye ne-twill. Ixabiso lalo eliphambili lisekukhuliseni ukugcinwa kweempawu zoomatshini kunye nokusebenza kweefayibha zebasalt ngoyilo lwesakhiwo "olujijwayo oluphantsi + ukuqhubeka okuphezulu," okwenza libe yindawo efanelekileyo yokuqinisa kwicandelo lezinto ezidityanisiweyo.

Izinto zefayibha yeBasalt zisetyenziswa ngamandla. Ngoko ke, iveliswa njani ifayibha yebasalt? Yifayibha eqhubekayo eyenziwe ngokutsalwa kwesantya esiphezulu kwezinto zelitye lebasalt emva kokuba zinyibilikisiwe kwi-1450°C ukuya kwi-1500°C nge-platinum-rhodium alloy spinneret. Ifayibha yebasalt inombala omdaka okanye wegolide. Ifayibha yebasalt luhlobo olutsha lwezinto zefayibha ezingaphiliyo, ezinobuhlobo nokusingqongileyo, eziluhlaza, nezisebenza kakuhle. Yinto entsha yenkulungwane yama-21 eluhlaza, enobuhlobo nokusingqongileyo, kwaye ayingcolisi, kwaye yenye yeefayibha ezine eziphambili zaseTshayina ezinobuhlobo nokusingqongileyo. Ifayibha yebasalt ibonisa iipropati ezibalaseleyo ngokwamandla, ukumelana namaqondo obushushu aphezulu naphantsi, ukumelana nokugqwala, ukuthintela ubushushu, ukuthintela isandi, ukuthintela ilangatye, kunye nokuthintela iikhemikhali kunye nombane.

Iphepha lophando elinesihloko esithi “Hierarchical basalt metayarn for ergonomic protective space textiles” lipapashwe kwijenali ethi Matter liqela likaNjingalwazi uXia Zhigang kunye neAcademician uXu Weilin ovela kwiNational Key Laboratory of New Textile Materials and Advanced Processing kwiYunivesithi yaseWuhan Textile, besebenzisana noNjingalwazi uTao Guangming.

Ifayibha yeBasalt ayibonakali nje kuphela ngamandla aphezulu, uzinzo oluhle lobushushu, ukumelana nomonakalo kwii-counterparts, ukuguguleka okuphantsi, kunye ne-coefficient yokungqubana okuzinzileyo, kodwa ikwabonakaliswa ngamaxabiso afanelekileyo. Ukusetyenziswa kwefayibha yeBasalt kwizixhobo eziphucula ukungqubana kuluncedo ekwandiseni ubomi bezixhobo zokungqubana kweemoto kunye nokuphucula ubushushu bazo bokusebenza. Ingasombulula neengxaki ezahlukeneyo ezikhoyo kwizixhobo zokungqubana zangoku, ezinceda ekusombululeni imeko yokuguguleka kobushushu kwiibhuleki zemoto zemveli, ngaloo ndlela kuncitshiswe ukwanda kweengozi zendlela.

Iiplastiki eziQinisekisiweyo zeBasalt Fiber (BFRP) zivela njengenye indlela enamandla endaweni yezinto zemveli, zibonelela ngomxube onomtsalane wokuzinza, ukusebenza okuphezulu, kunye nokusebenza kakuhle kweendleko. Ezivela kwilitye lentaba-mlilo, iifayibha zebasalt zineempawu eziphezulu zoomatshini, uzinzo oluhle kakhulu lweekhemikhali, kunye nobuhlobo nokusingqongileyo. Ezi mpawu zibeka iBFRP njengento etshintsha umdlalo kumashishini abalulekileyo, ngakumbi lawo abeka phambili izakhiwo ezikhaphukhaphu, ukuqina, kunye nokumelana neendawo ezinzima.

Indawo yomboniso e Umboniso weeComposites zase-Eurasia e-Istanbul, eTurkey, itshintshile ukusuka kwiHolo 6, iBooth B540 ukuya kwiHolo 5, iBooth B540.

I-basalt fiber eqoshiweyo ene-asidi yi-basalt fiber ephathwe ngokukodwa eneempawu zomzimba nezekhemikhali ezikhethekileyo.

Ifayibha yeBasalt yifayibha engaphiliyo eyenziwe ngeminerali yendalo yelitye le-basalt, enyibilikiswa kubushushu obuphezulu ize itsalwe ibe yifayibha. Ikwicandelo lefayibha esebenza kakhulu, efana nefayibha yeglasi eqhelekileyo kunye nefayibha yekhabhoni, kodwa yahlukile kumthombo wezinto ezikrwada, inkqubo yemveliso, kunye nemiba ethile yokusebenza. Oku kulandelayo kuhlalutya itekhnoloji yefayibha ye-basalt kwiinkalo ezahlukeneyo.

Kule minyaka yangoku, Ulwakhiwo lobunjineli beendlela ezinkulu eTshayina luphuhlile ngokukhawuleza, kunye netekhnoloji yesakhiwo sekhonkrithi ifikelele kwinkqubela phambili ebalulekileyo, ukuqokelelana kwee-advanced kunye nee-mat ezininziimpumelelo yobugcisa. Uyilo lwesakhiwo sekhonkrithi luye lwasetyenziswa kakhulu kwicandelo lokwakhiwa kweziseko zophuhliso, nto leyo ebonisa ukubaluleka kwalo. Nangona kunjalo, kunye nezi mpumelelo, ingxaki yokuqhekeka kwekhonkrithi iya isiba yinto ephawulekayo. Ubukho beentanda buphazamisa ukusebenza kwekhonkrithi, ngokukodwa ukunciphisa amandla ayo okutyhafa, okuyiyo eyona nto iphambiliisizathu sokungaphumeleli okubonakalayo yikhonkrithi. Ifayibha yebasalt enqunyulwe mfutshane, njengezinto ezintsha zefayibha, iye yaba yinto ebalaseleyo yokuqinisa ikhonkrithi ngenxa yeempawu zayo ezikhethekileyo zoomatshini, uzinzo oluhle, kunye nokusebenza kakuhle kweendleko. Eli nqaku liza kugxila kwiimpawu zefayibha ye-basalt enqunyulwe kancinci kwaye lihlolisise ukusetyenziswa kwayo okusebenzayo ekuqiniseni nasekuqiniseni ikhonkrithi.
