Iindaba

Iibhulorho ezinqumla ulwandle, iziphelo zamanzi anzulu, iifama zomoya ezingaphandle kolwandle... Nangona ezi "ziinkunzi ezinkulu" ezakhiwe elwandle zintle ukuzibona, zinyamezela "intlungu ebuhlungu" yemihla ngemihla yokukhukuliseka kwamaza, ityuwa kunye nokubola kwe-alkali, kunye nemijikelo etshintshanayo emanzi neyomileyo. Kwimeko enjalo, ukuqinisekisa ukuba izakhiwo zekhonkrithi eziqinileyo zihlala zinjalo—zingenakwaphuka, ziqhekeke, okanye zingasebenzi kakuhle—kudala kube ngumngeni onzima kuluntu lobunjineli behlabathi.

Kangangexesha elide, imicu yentsimbi ibisoloko ifakwa kwikhonkrithi ukuze yomeleze ukuqina kwayo kwaye ithintele ukuqhekeka. Nangona kunjalo, imicu yentsimbi idla ngokungafaneleki kwiimeko ezinzima zokutshizwa ngetyuwa kunye namanzi olwandle; xa ii-ion ze-chloride zingena kwimingxuma engaphakathi kwikhonkrithi, imicu yentsimbi iyagqwala kwaye yande ngobuninzi, nto leyo ebangela ukuba ikhonkrithi iqhekeke ngaphakathi ize ikhawulezise ukuqhekeka kwesakhiwo.
Kutshanje, uphando olutsha lwezinto ezijoliswe ekuqineni okuphezulu kobunjineli bezolwandle lunikeze isisombululo esithembisayo kakhulu: iifayibha ze-basalt—eziveliswa ngokutsala imicu evela kwilitye lentaba-mlilo yendalo—zingasetyenziswa ukugquma ikhonkrithi yolwandle kumaleko “wezixhobo” ezingathintelwanga kukugqwala. Oku kufezekiswa ngemodeli yokulinganisa ubungakanani obuninzi equka indibaniselwano “yeefayibha ezinkulu zokubopha izakhiwo” kunye “neefayibha ezincinci zokuvala iimbobo.”

Kwicandelo lezinto zokuqinisa i-concrete, itekhnoloji entsha ibangela utshintsho olukhulu kushishino. Inkampani ephambili yokuvelisa izinto ezintsha kutshanje ibhengeze ukuba imveliso yayo ephambili - i-basalt fiber efana ne-hinge enobubanzi obuziimilimitha ezili-0.7 kunye nobude obuziimilimitha ezili-12/35/50 - ifikelele kwimveliso yemizi-mveliso. Iya kusetyenziswa ikakhulu kwizakhiwo ze-concrete ezisebenza kakuhle, isombulula ngempumelelo ingxaki yokuqina kwexesha elide.

Ifayibha yeBasalt, "ifayibha eluhlaza esebenza kakhulu" ephuma kwi-basalt ore yendalo, ineenzuzo ezifana nokumelana nobushushu obuphezulu, ukumelana nokugqwala kweekhemikhali, iipropati ezibalaseleyo zoomatshini, kunye nokubola kwendalo, okukhokelela ekuphuhlisweni kweemveliso ezahlukeneyo ezinexabiso eliphezulu kwishishini lempahla. Phakathi kwezi, intambo engajijwanga kunye nelaphu elingalukwanga zezona zimbini zezona zisetyenziswa kakhulu kwaye zibalulekileyo. Zixhomekeke kwiinkqubo ezahlukeneyo zelaphu kunye neempawu zesakhiwo, ngokulandelelana zifezekisa amandla ahlukeneyo kwiindawo ezifana nokuqinisa izinto ezidityanisiweyo eziphezulu, ukhuseleko lwemizi-mveliso, kunye nokuhluzwa kwendalo.

Ilaphu le-basalt fiber elisemgangathweni ophezulu elenzelwe ngokukodwa ukuvelisa ibhodi ye-epoxy resin laminates esebenza kakuhle. Lisebenzisa ii-basalt fibers eziqhubekayo ngokusebenzisa iinkqubo zokuluka ezikhethekileyo kunye nonyango lomphezulu ukuze lifumane ukumanzisa okungcono kunye nokunamathela kwinkqubo ye-epoxy resin, izixhobo zokugqibela ezidityanisiweyo ezineempawu ezibalaseleyo zoomatshini, ukumelana nobushushu kunye nokumelana nokugqwala.

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.

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

IGLASI YEFAYIBHASI YASETSHAYINA BEIHAI inomdla wokubhengeza ukuba ithatha inxaxheba kwi-7th International Composites Industry Exhibition (Eurasian Composites Show) kwi-Istanbul Expo Center, eTurkey, ukususela nge-26-28 kaNovemba, 2025. Sibamema ngokufudumeleyo bonke abakhoyo ukuba batyelele i-booth yethu baze bahlole amandla amakhulu ezinto zethu ze-phenolic fiberglass composite eziphucukileyo.

Ifayibha yeBasalt, enebasalt yendalo njengezinto zayo eziluhlaza, yenziwa ibe yi-filament bundle eqhubekayo, entle engaphiliyo emva kokunyibilika, ukutsalwa, kunye nonyango lobushushu. Ifayibha yeBasalt inokumelana nobushushu obuphezulu, i-anti-oxidation, i-radiation resistance, i-thermal kunye ne-acoustic insulation, kunye nokusebenza kakuhle kokuhluza. Ngenxa yokuba inkqubo yayo yokuvelisa icocekile kwaye ayinangcoliseko, yaziwa ngokuba "yizinto zoshishino eziluhlaza zenkulungwane yama-21." Emva koko icutshungulwa ngakumbi ibe yi-composite bar enesimo se-rebar.

Ukusasazwa kwefayibha okungalinganiyo ngexesha lenkqubo yokuxuba kunokukhokelela ekuqineni kwendawo yesamente, okuchaphazela ukumelana kwayo neentanda. Ukuphucula ukusasazeka kwefayibha, izixhobo zokuxuba ezisebenzayo kufuneka isetyenziswe, kwaye ixesha lokuxuba kunye nesantya kufuneka kulungiswe ngokufanelekileyo ukuqinisekisa ukusasazwa kwefayibha ngokulinganayo kulo lonke udaka. Ixesha elifanelekileyo lokuxuba linceda ukuqinisekisa ukuba iifayibha zidityaniswe ngokupheleleyo nezinto ezisekwe kwisamente; amaxesha okuxuba amade kakhulu okanye amafutshane kakhulu aya kuchaphazela ukusasazwa kwefayibha kunye nokusebenza ngokubanzi kodaka. Ngokuqhelekileyo kuyacetyiswa ukuba lawula ixesha lokuxuba libe yimizuzu emi-3-5, ukuphepha ukuxuba kakhulu, okunokubangela ukwaphuka kwefayibha kwaye kuchaphazele kakubi isiphumo sokuqinisa.
