I-Basalt Fiber
I-Basalt fiber iyi-fiber eqhubekayo ethathwe ku-basalt yemvelo. Iyitshe le-basalt ku-1450 ℃ ~ 1500 ℃ ngemva kokuncibilika, ngokusebenzisa ipuleti lokudonsa elivunguzayo nge-platinum-rhodium alloy wire drawing high-speed dopping elenziwe nge-fiber eqhubekayo. Umbala we-basalt fiber yemvelo emsulwa ngokuvamile unombala onsundu. I-Basalt fiber uhlobo olusha lwezinto ze-fiber eziluhlaza ezisebenza kahle kakhulu ezingaphili, ezakhiwe nge-silica, i-alumina, i-calcium oxide, i-magnesium oxide, i-iron oxide kanye ne-titanium dioxide kanye nezinye i-oxide.I-fiber eqhubekayo ye-basaltAyigcini nje ngokuba namandla aphezulu, kodwa futhi inezakhiwo eziningi ezinhle kakhulu njengokushisa kukagesi, ukumelana nokugqwala, ukumelana nokushisa okuphezulu nokunye. Ngaphezu kwalokho, inqubo yokukhiqiza i-basalt fiber yanquma ukukhiqiza imfucuza encane, ukungcola okuncane emvelweni, futhi umkhiqizo ungawohloka ngqo emvelweni ngemuva kwemfucuza, ngaphandle kokulimaza, ngakho-ke iyinto eluhlaza yangempela, enobungani nemvelo. Imicu eqhubekayo ye-basalt isetshenziswe kabanzi ezintweni eziqiniswe yi-fiber, izinto zokungqubuzana, izinto zokwakha imikhumbi, izinto zokuvimbela ukushisa, imboni yezimoto, izindwangu zokuhlunga ezishisa kakhulu, kanye nezinsimu zokuvikela.
Izici
① Izinto zokusetshenziswa ezanele
I-Basalt fiberyenziwe nge-basalt ore encibilikisiwe futhi idonswe, kanti i-basalt ore eMhlabeni naseNyangeni iyizinqolobane eziqondile, kusukela ezindleko zezinto zokusetshenziswa ziphansi kakhulu.
② Izinto ezinobungani nemvelo
I-Basalt ore iyinto yemvelo, ayikho i-boron noma amanye ama-alkali metal oxides akhishwa ngesikhathi senqubo yokukhiqiza, ngakho-ke azikho izinto eziyingozi ezitholakala entuthwini, umkhathi ngeke ubangele ukungcola. Ngaphezu kwalokho, umkhiqizo uhlala isikhathi eside, ngakho-ke uwuhlobo olusha lwezinto zokuvikela imvelo eziluhlaza ezisebenza kahle ezinezindleko eziphansi, ukusebenza okuphezulu kanye nokuhlanzeka okuhle.
③ Ukushisa okuphezulu kanye nokumelana namanzi
Ububanzi bokushisa bokusebenza kwe-basalt fiber obuqhubekayo ngokuvamile bungu-269 ~ 700 ℃ (iphuzu lokuthambisa elingu-960 ℃), kuyilapho i-fiber yengilazi engu-60 ~ 450 ℃, izinga lokushisa eliphakeme kakhulu le-carbon fiber lingafinyelela ku-500 ℃ kuphela. Ikakhulukazi, i-basalt fiber engu-600 ℃ isebenza, amandla ayo ngemva kokuphumula asengagcina u-80% wamandla okuqala; ukusebenza ku-860 ℃ ngaphandle kokuncipha, noma ngabe ukumelana nokushisa koboya obuhle kakhulu bamaminerali ngalesi sikhathi ngemva kokuphumula kungagcinwa ku-50% -60% kuphela, uboya bengilazi bubhujiswa ngokuphelele. I-carbon fiber cishe ku-300 ℃ ekukhiqizweni kwe-CO2 ne-CO2. I-basalt fiber ku-70 ℃ ngaphansi kwesenzo samanzi ashisayo ingagcina amandla aphezulu, i-basalt fiber emahoreni angu-1200 ingalahlekelwa ingxenye yamandla.
④ Ukuqina okuhle kwamakhemikhali kanye nokumelana nokugqwala
I-fiber ye-basalt eqhubekayo iqukethe i-K2O, i-MgO) kanye ne-TiO2 nezinye izingxenye, futhi lezi zingxenye zokuthuthukisa ukumelana nokugqwala kwamakhemikhali kwe-fiber nokusebenza okungangeni manzi kuzuzisa kakhulu, kudlala indima ebaluleke kakhulu. Kunenzuzo kakhulu uma kuqhathaniswa nokuzinza kwamakhemikhali kwe-fiber yengilazi, ikakhulukazi kwimidiya ye-alkaline ne-acidic, i-fiber ye-basalt esobala kakhulu kwisisombululo se-Ca (OH) 2 esigcwele kanye ne-samente kanye nezinye imidiya ye-alkaline nazo zingagcina ukumelana okuphezulu ekusebenzeni kokugqwala kwe-alkaline.

⑤ I-modulus ephezulu yokunwebeka kanye namandla okudonsa
I-modulus yokunwebeka kwe-basalt fiber ingu-9100 kg/mm-11000 kg/mm, okuphakeme kune-fiber yengilazi engena-alkali, i-asbestos, i-aramid fiber, i-polypropylene fiber kanye ne-silica fiber. Amandla okunwebeka kwe-basalt fiber angu-3800–4800 MPa, okuphakeme kune-fiber enkulu ye-tow carbon, i-aramid fiber, i-PBI fiber, i-steel fiber, i-boron fiber, i-alumina fiber, futhi ifana ne-S glass fiber. I-basalt fiber inobuningi obungu-2.65-3.00 g/cm3 kanye nobunzima obuphezulu obungu-5-9 degrees esikalini sobunzima be-Mohs, ngakho-ke inokumelana okuhle kakhulu kokuguguleka kanye nezakhiwo zokuqinisa ukunwebeka. Amandla ayo okusebenza adlula kakhulu lawo e-fiber yemvelo kanye ne-fibre yokwenziwa, ngakho-ke iyinto efanelekile yokuqinisa, futhi izakhiwo zayo ezinhle kakhulu zomshini ziphambili kwezintambo ezine ezinkulu zokusebenza okuphezulu.
⑥ Ukusebenza okuhle kakhulu kokuvikela umsindo
I-fiber ye-basalt eqhubekayo inokushisa okuhle kakhulu komsindo, ukusebenza kahle kokumuncwa komsindo, kusukela ku-fiber e-coefficient ehlukene yokumuncwa komsindo kungafundwa, ngokwanda kwemvamisa, i-coefficient yayo yokumuncwa komsindo iyanda kakhulu. Njengokukhethwa kobubanzi be-fiber ye-basalt engu-1-3μm eyenziwe ngezinto ezimunca umsindo (ubude obungu-15 kg/m3, ubukhulu obungu-30mm), kumsindo wezimo ze-100-300 Hz, 400-900 Hz kanye ne-1200-7,000 HZ, i-coefficient yokumuncwa kwezinto ze-fiber engu-0.05~0.15, 0.22~0.75 kanye no-0.85~0.93, ngokulandelana.
⑦ Izakhiwo ezivelele ze-dielectric
Ukumelana kwevolumu ye-fiber ye-basalt eqhubekayo kuphakeme kakhulu kunokwe-I-fiber yengilazi ye-E, enezakhiwo ezinhle kakhulu ze-dielectric. Nakuba i-basalt ore iqukethe ingxenye enkulu cishe engu-0.2 yama-oxide aqhubayo, kodwa ukusetshenziswa kwe-agent ekhethekile yokungena ngaphakathi kwelashwa okukhethekile kwendawo, i-angle yokusebenzisa i-dielectric ye-basalt fiber kune-fiber yengilazi iphansi ngo-50%, ukumelana kwevolumu ye-fiber nakho kuphakeme kune-fiber yengilazi.

⑧ Ukuhambisana kwe-silicate yemvelo
Ukusabalala okuhle ngesamente nokhonkolo, ukubopha okuqinile, i-coefficient ehambisanayo yokwanda nokuncipha kokushisa, ukumelana nesimo sezulu okuhle.
⑨ Ukumuncwa komswakama okuphansi
Ukumuncwa komswakama kwe-basalt fiber kungaphansi kuka-0.1%, kuphansi kune-aramid fiber, i-rock wool kanye ne-asbestos.
⑩ Ukushisa okuphansi
Ukushisa kwe-basalt fiber kungu-0.031 W/mK – 0.038 W/mK, okuphansi kunokwe-aramid fiber, i-alumino-silicate fiber, i-alkali-free glass fiber, i-rockwool, i-silicon fiber, i-carbon fiber kanye nensimbi engagqwali.

I-fiberglass
I-Fiberglass, into engeyona eyensimbi engaphili enomsebenzi omuhle kakhulu, inezinzuzo eziningi ezifana nokushisa okuhle, ukumelana nokushisa, ukumelana nokugqwala okuhle, amandla aphezulu omshini, kodwa ukungathandeki ukumelana nokuqhekeka nokungavuvukali kahle. Isekelwe ku-chlorite, isihlabathi se-quartz, i-limestone, i-dolomite, itshe le-boron calcium, itshe le-boron magnesium, izinhlobo eziyisithupha zama-ore njengezinto zokusetshenziswa ngokuncibilika okushisa okuphezulu, ukudweba, ukugoqa, ukweluka nezinye izinqubo ekwakhiweni kobubanzi be-monofilament yayo yama-micron ambalwa kuya kuma-micron angaphezu kwama-20, okulingana noboya obuyi-1/20-1/5, inqwaba ngayinye ye-filament ye-fiber ingamakhulu noma ngisho nezinkulungwane zokwakheka kwe-monofilament.I-fiberglassivame ukusetshenziswa njengezinto zokuqinisa ezintweni ezihlanganisiwe, izinto zokuvimbela ugesi kanye nezinto zokuvimbela ukushisa, amabhodi wesekethe kanye nezinye izindawo zomnotho wezwe.

Izakhiwo Zezinto
Iphuzu lokuncibilika: ingilazi uhlobo lwephuzu lokuncibilika elingaguquki, elingenalo iphuzu lokuncibilika eliqondile, ngokuvamile kukholelwa ukuthi iphuzu lokuncibilika lingu-500 ~ 750 ℃.
Iphuzu lokubilisa: cishe i-1000 ℃
Ubuningi: 2.4~2.76 g/cm3
Uma i-fiber yengilazi isetshenziswa njengezinto zokuqinisa amapulasitiki aqinisiwe, isici esikhulu kunazo zonke amandla ayo aphezulu okubamba. Amandla okubamba esimweni esijwayelekile angama-6.3 ~ 6.9 g / d, isimo esimanzi singama-5.4 ~ 5.8 g / d. Ukumelana nokushisa kuhle, izinga lokushisa lifinyelela kuma-300 ℃ ngamandla angenamphumela. Ine-insulation kagesi enhle kakhulu, iyinto yokuvikela kagesi esezingeni eliphezulu, futhi isetshenziselwa izinto zokuvikela kanye nezinto zokuvikela umlilo. Ngokuvamile igqwala kuphela yi-alkali egxilile, i-hydrofluoric acid kanye ne-phosphoric acid egxilile.
