I-Basalt Fiber
I-basalt fiber iyifayibha eqhubekayo ethathwe ku-basalt yemvelo. Kuyitshe le-basalt ku-1450 ℃ ~ 1500 ℃ ngemva kokuncibilika, ngokusebenzisa i-platinum-rhodium alloy wire drawing plate yokuvuza ipuleti elidonsa ngesivinini esikhulu elenziwe ngefayibha eqhubekayo. Umbala we-basalt fiber yemvelo ehlanzekile ngokuvamile unsundu. I-Basalt fibre iwuhlobo olusha lwezinto ezingaphili ezithinta imvelo eziluhlaza ezisebenza kahle kakhulu, ezakhiwe nge-silica, i-alumina, i-calcium oxide, i-magnesium oxide, i-iron oxide ne-titanium dioxide namanye ama-oxide.I-basalt fiber eqhubekayoayigcini nje ngokuba namandla aphezulu, kodwa futhi inezinhlobonhlobo zezakhiwo ezinhle kakhulu ezifana nokufakwa kukagesi, ukumelana nokugqwala, ukumelana nokushisa okuphezulu nokunye. Ngaphezu kwalokho, inqubo yokukhiqiza ye-basalt fiber yanquma ukukhiqiza imfucuza encane, ukungcola okuncane emvelweni, futhi umkhiqizo ungonakaliswa ngokuqondile emvelweni ngemva kokulahlwa, ngaphandle kokulimala, ngakho-ke uhlaza lwangempela, izinto ezithinta imvelo. Imicu eqhubekayo ye-Basalt isetshenziswe kabanzi ekuhlanganiseni okuqiniswe ngefayibha, izinto zokungqubuzana, izinto zokwakha umkhumbi, izinto ezibamba ukushisa, imboni yezimoto, izindwangu zokuhlunga ezishisa kakhulu, kanye nezinkundla zokuvikela.
Izici
① Izinto zokusetshenziswa ezanele
I-basalt fiberyenziwe nge-basalt ore encibilikisiwe futhi idonswa, futhi i-basalt ore eMhlabeni nasenyanga iyimithombo eqondile, kusukela ezindlekweni zezinto ezingavuthiwe ziphansi kakhulu.
② Izinto ezihambisana nemvelo
I-Basalt ore iyinto engokwemvelo, ayikho i-boron noma amanye ama-alkali ensimbi ensimbi akhishwa ngesikhathi sokukhiqiza, ngakho-ke azikho izinto eziyingozi ezishiswa intuthu, umkhathi ngeke ubangele ukungcola. Ngaphezu kwalokho, umkhiqizo unokuphila okude, ngakho-ke kuwuhlobo olusha lwezinto eziluhlaza ezisebenzayo zokuvikela imvelo ezinezindleko eziphansi, ukusebenza okuphezulu kanye nokuhlanzeka okufanele.
③ Izinga lokushisa eliphezulu nokumelana namanzi
Ibanga lokushisa eliqhubekayo le-basalt fiber esebenzayo ngokuvamile lingama-269 ~ 700 ℃ (iphuzu lokuthambisa lika-960 ℃), kuyilapho i-fiber yengilazi engu-60 ~ 450 ℃, izinga lokushisa eliphakeme kakhulu le-carbon fiber lingafinyelela ku-500 ℃ kuphela. Ikakhulukazi, i-basalt fiber ku-600 ℃ umsebenzi, amandla ayo emva kwekhefu asengakwazi ukugcina u-80% wamandla okuqala; sebenza ku-860 ℃ ngaphandle kokushwabana, ngisho noma ukumelana kwezinga lokushisa loboya obuhle kakhulu bamaminerali ngalesi sikhathi ngemva kwekhefu kungagcinwa kuphela ku-50% -60%, uboya bengilazi bubhujiswa ngokuphelele. I-Carbon fiber cishe i-300 ℃ ekukhiqizeni kwe-CO ne-CO2. I-basalt fiber ku-70 ℃ ngaphansi kwesenzo samanzi ashisayo ingagcina amandla aphezulu, i-basalt fiber ku-1200 h ingase ilahlekelwe ingxenye yamandla.
④ Ukuzinza okuhle kwamakhemikhali nokumelana nokugqwala
I-basalt fiber eqhubekayo iqukethe i-K2O, i-MgO) ne-TiO2 nezinye izakhi, futhi lezi zingxenye zokuthuthukisa ukumelana nokugqwala kwamakhemikhali kwefayibha nokusebenza okungangeni kwamanzi kunenzuzo enkulu, zidlala indima ebaluleke kakhulu. Kuzuzisa kakhulu uma kuqhathaniswa nokuzinza kwamakhemikhali emicu yengilazi, ikakhulukazi emicu ye-alkaline ne-acidic esobala kakhudlwana emicu ye-basalt kusisombululo esigcwele se-Ca (OH) 2 nosimende neminye imithombo ye-alkaline futhi ingagcina ukumelana okuphezulu nokusebenza kokugqwala kwe-alkali.

⑤ I-modulus ephezulu yokunwebeka namandla aqinile
I-modulus ye-elasticity ye-basalt fiber ingu-9100 kg/mm-11000 kg/mm, ephakeme kunaleyo ye-alkali-free glass fiber, i-asbestos, i-aramid fiber, i-polypropylene fiber kanye ne-silica fiber. Amandla aqinile we-basalt fiber yi-3800–4800 MPa, ephakeme kunaleyo ye-tow carbon fiber enkulu, i-aramid fiber, i-PBI fiber, i-steel fibre, i-boron fiber, i-alumina fiber, futhi iqhathaniswa ne-S glass fiber. Ifayibha ye-basalt inokuminyana okungu-2.65-3.00 g/cm3 kanye nobulukhuni obuphezulu obungu-5-9 degrees esikalini sokuqina se-Mohs, ngaleyo ndlela inokumelana okuhle kakhulu nokuhuzuka kanye nezindawo zokuqinisa amandla. Amandla ayo okusebenza awadlula kude awemicu yemvelo nemicu yokwenziwa, ngakho iyinsimbi eqinisayo ekahle, futhi izici zayo ezinhle kakhulu zemishini zihamba phambili emiculweni emine emikhulu esebenza kahle kakhulu.
⑥ Ukusebenza okuvelele kokufakwa komsindo
I-basalt fibre eqhubekayo inokwehlukanisa umsindo okuhle kakhulu, ukusebenza kokumuncwa komsindo, kusuka ku-fiber ehlukene yokumuncwa komsindo womsindo kungafundwa, ngokwanda kwemvamisa, i-coefficient yayo yokumunca umsindo ikhuphuka kakhulu. Njengokukhethwa kobubanzi obungu-1-3μm ifayibha ye-basalt eyenziwe (ukuminyana kuka-15 kg/m3, ukujiya okungu-30mm) izinto ezimunca umsindo, kumsindo we-100-300 Hz, 400-900 Hz kanye nezimo ezingu-1200-7,000 HZ, ukumuncwa okubalulekile kwefayibha ~010.50. 0.22~0.75 kanye 0.85~0.93, ngokulandelana.
⑦ Izakhiwo ezivelele ze-dielectric
Ukumelana nevolumu ye-basalt fiber eqhubekayo kuwuhlelo olulodwa lobukhulu obuphakeme kunalelo lwe-E glass fiber, enezici ezinhle kakhulu ze-dielectric. Nakuba insimbi ye-basalt iqukethe ingxenye enkulu ecishe ibe ngu-0.2 yama-oxide e-conductive, kodwa ukusetshenziswa kwe-ejenti ekhethekile yokwelashwa okukhethekile kwendawo, i-basalt fiber dielectric ukusetshenziswa kwe-angle tangent kune-fiber yengilazi iphansi ngo-50%, ivolumu yokumelana ne-fiber nayo iphakeme kune-fiber yengilazi.

⑧ Ukuhambisana kwe-silicate yemvelo
Ukuhlakazeka okuhle ngosimende nokhonkolo, ukubopha okuqinile, i-coefficient engaguquki yokwanda nokufinyela okushisayo, ukumelana nesimo sezulu esihle.
⑨ Ukumunca umswakama ophansi
Ukumuncwa komswakama we-basalt fiber kungaphansi kuka-0.1%, kuphansi kune-aramid fiber, uboya bedwala ne-asbestos.
⑩ Ukusebenza okuphansi kwe-thermal
I-thermal conductivity ye-basalt fiber ingu-0.031 W/mK - 0.038 W/mK, ephansi kunaleyo ye-aramid fiber, i-alumino-silicate fiber, i-alkali-free glass fiber, i-rockwool, i-silicon fiber, i-carbon fibre nensimbi engagqwali.

I-Fiberglass
I-Fiberglass, i-inorganic non-metallic material esebenza kahle kakhulu, inezinhlobonhlobo zezinzuzo ezifana nokufakwa kahle, ukumelana nokushisa, ukumelana nokugqwala okuhle, amandla aphezulu emishini, kodwa ububi buwubukhazikhazi kanye nokungazweli kahle komhuzuko. Isekelwe ku-chlorite, isihlabathi se-quartz, i-limestone, i-dolomite, itshe le-boron calcium, itshe le-boron magnesium izinhlobo eziyisithupha ze-ores njengezinto zokusetshenziswa ngokuncibilika kwezinga lokushisa eliphezulu, ukudweba, ukugoqa, ukuluka kanye nezinye izinqubo ekwenzeni ububanzi be-monofilament yayo yama-microns ambalwa kuya kuma-microns angaphezu kuka-20, okulingana no-1/5 / 20 wezinwele ze-fiber ngayinye. amakhulu noma izinkulungwane zokwakheka kwe-monofilament.I-Fiberglassngokuvamile isetshenziswa njengezinto eziqinisayo ezintweni ezihlanganisiwe, izinto zokufaka ugesi kagesi kanye nezinto zokushisa ezishisayo, amabhodi wesekethe nezinye izindawo zomnotho kazwelonke.

Izinto ezibonakalayo
Iphuzu elincibilikayo: ingilazi iwuhlobo lwe-non-crystalline, ayikho indawo encibilikayo engaguquki, ngokuvamile kunenkolelo yokuthi indawo yokuthambisa ingu-500 ~ 750 ℃.
Indawo yokubilisa: mayelana ne-1000 ℃
Ukuminyana: 2.4~2.76 g/cm3
Lapho i-glass fiber isetshenziswa njengezinto eziqinisayo zamapulasitiki aqinisiwe, isici esikhulu kunazo zonke amandla ayo aqinile. Amandla okuqinile esimweni esijwayelekile ngu-6.3 ~ 6.9 g / d, isimo esimanzi 5.4 ~ 5.8 g / d. Ukumelana nokushisa kuhle, izinga lokushisa lifinyelela ku-300 ℃ ngamandla angenamphumela. Ine-insulation kagesi enhle kakhulu, iyimpahla yokufakelwa kagesi esezingeni eliphezulu, esetshenziselwa izinto zokuvikela kanye nezinto zokuvikela umlilo. Ngokuvamile kugqwala kuphela i-alkali egxilile, i-hydrofluoric acid ne-concentrated phosphoric acid.
