Basalt Fiber
Basalt fiber ke fiber e tsoelang pele e nkiloeng ho basalt ea tlhaho. Ke lejoe la basalt ka 1450 ℃ ~ 1500 ℃ ka mor'a ho qhibiliha, ka platinum-rhodium alloy terata ea leakage plate e hulang ka lebelo le phahameng e entsoeng ka fiber e tsoelang pele. 'Mala oa fiber ea tlhaho ea basalt e hloekileng hangata e sootho. Basalt faeba ke mofuta o mocha oa inorganic tikoloho botsoalle botala botala bo phahameng-tshebetso faeba lintho tse bonahalang, e leng entsoe ka silika, alumina, calcium oxide, magnesium oxide, tšepe oxide le titanium dioxide le oxides tse ling.Basalt fiber e tsoelang peleha e na matla a phahameng feela, empa hape e na le mefuta e fapaneng ea lintho tse babatsehang tse kang ho kenya motlakase, ho hanyetsa kutu, ho hanyetsa mocheso o phahameng joalo-joalo. Ho phaella moo, ts'ebetso ea tlhahiso ea fiber ea basalt e ile ea etsa qeto ea ho hlahisa litšila tse fokolang, tšilafalo e nyenyane ho tikoloho, 'me sehlahisoa se ka senyeha ka ho toba tikolohong ka mor'a litšila, ntle le kotsi leha e le efe, kahoo ke thepa ea sebele e tala, e nang le tikoloho. Likhoele tse tsoelang pele tsa Basalt li 'nile tsa sebelisoa haholo ho li-composites tse matlafalitsoeng ka fiber, thepa ea likhohlano, thepa ea ho haha ​​​​likepe, lisebelisoa tse thibelang mocheso, indasteri ea likoloi, masela a hloekisang mocheso o phahameng le masimo a sireletsang.

① Lisebelisoa tse lekaneng tse tala
Basalt fiberE entsoe ka ore ea basalt e qhibilihisitsoeng le ho huloa, 'me ore ea basalt Lefatšeng le khoeli ke mehloli e mengata, ho tloha litšenyehelong tsa thepa e tala li batla li le tlaase.
② Lintho tse bolokang tikoloho
Basalt ore ke thepa ea tlhaho, ha ho na boron kapa li-oxide tse ling tsa alkali tse ntšoang nakong ea tlhahiso, kahoo ha ho na lintho tse kotsi tse kenngoang mosing, sepakapaka se ke ke sa baka tšilafalo. Ho feta moo, sehlahisoa sena se na le nako e telele, kahoo ke mofuta o mocha oa thepa ea ts'ireletso ea tikoloho e tala e sebetsang ka theko e tlaase, ts'ebetso e phahameng le bohloeki bo loketseng.
③ Mocheso o phahameng le ho hanyetsa metsi
Mocheso o tsoelang pele oa basalt fiber e sebetsang ka kakaretso ke 269 ~ 700 ℃ (bonolo ba ntlha ea 960 ℃), ha fiber ea khalase bakeng sa 60 ~ 450 ℃, mocheso o phahameng ka ho fetisisa oa carbon fiber o ka fihla ho 500 ℃ feela. Haholo-holo, fiber ea basalt e sebetsang ka 600 ℃, matla a eona ka mor'a khefu e ntse e ka boloka 80% ea matla a pele; sebetsa ka 860 ℃ ntle le shrinkage, esita le haeba ho hanyetsa mocheso oa boea bo botle ba diminerale ka nako ena ka mor'a khefu e ka bolokoa feela ho 50% -60%, boea ba khalase bo senyeha ka ho feletseng. Carbon fiber e ka bang 300 ℃ tlhahisong ea CO le CO2. Basalt fiber ka 70 ℃ tlas'a ketso ea metsi a chesang e ka boloka matla a phahameng, fiber ea basalt ka 1200 h e ka lahleheloa ke karolo ea matla.
④ Botsitso bo botle ba lik'hemik'hale le ho hanyetsa kutu
Fiber e tsoelang pele ea basalt e na le K2O, MgO) le TiO2 le likarolo tse ling, 'me likarolo tsena tsa ho ntlafatsa khanyetso ea lik'hemik'hale tsa fiber le ts'ebetso e sa keneleng metsi li molemo haholo, li bapala karolo ea bohlokoa haholo. Ho molemo ho feta ha ho bapisoa le botsitso ba lik'hemik'hale tsa likhoele tsa khalase, haholo-holo mecheng ea alkaline le acidic media e hlakileng haholoanyane ea basalt ka tharollo ea saturated Ca (OH) 2 le samente le mecha e meng ea alkaline e ka boela ea boloka ts'ebetso e phahameng ea ho hanyetsa ts'ebetso ea alkali corrosion.

⑤ Modulus e phahameng ea elasticity le matla a thata
Modulus ea elasticity ea fiber ea basalt ke 9100 kg / mm-11000 kg / mm, e phahameng ho feta ea alkali-free glass fiber, asbestos, fiber ea aramid, polypropylene fiber le silica fiber. Matla a thata a basalt fiber ke 3800-4800 MPa, e phahameng ho feta ea fiber e kholo ea tow carbon, fiber ea aramid, fiber ea PBI, fiber ea tšepe, fiber ea boron, fiber ea alumina, 'me e bapisoa le S glass fiber. Basalt fiber e na le boima ba 2.65-3.00 g/cm3 le boima bo phahameng ba likhato tse 5-9 sekala sa boima ba Mohs, ka hona e na le ts'ebetso e ntle haholo ea ho hanyetsa le ho tiisa matla. Matla a eona a mochine a feta hōle a likhoele tsa tlhaho le likhoele tsa maiketsetso, kahoo ke thepa e matlafatsang e loketseng, 'me thepa ea eona e babatsehang ea mechine e ka pele ho likhoele tse 'nè tse phahameng tse sebetsang hantle.
⑥ Ts'ebetso e ikhethang ea ho koala molumo
Fiber ea basalt e tsoelang pele e na le ts'ebetso e ntle ea molumo, ts'ebetso ea ho monya molumo, ho tloha ho faeba ka har'a coefficient e fapaneng ea molumo oa molumo e ka ithutoang, ka keketseho ea maqhubu, coefficient ea eona ea ho monya molumo e eketseha haholo. Joalo ka khetho ea bophara ba 1-3μm basalt fiber e entsoeng ka (botenya ba 15 kg/m3, botenya ba 30mm) lisebelisoa tse monyang molumo, molumong oa 100-300 Hz, 400-900 Hz le 1200-7,000 HZ maemo, fiber material absorption ~010. 0.22 ~ 0.75 le 0.85 ~ 0.93, ka ho latellana.
