Basalt Fiber ke eng?
Basalt fiber ke fiber e tsoelang pele e entsoeng ka lejoe la tlhaho la basalt e le eona ntho e ka sehloohong e tala.Ka mor'a ho qhibiliha ho 1450-1500 ℃, e huloa ka setšoantšo sa platinum-rhodium alloy bushing ka lebelo le phahameng.Mmala ka kakaretso o sootho mme o na le ho benya ha metallic.E entsoe ka li-oxide tse kang silicon dioxide, aluminium oxide, calcium oxide, magnesium oxide, iron oxide le titanium dioxide.Basalt fiber e na le lintho tse ngata tse ntle tse kang matla a phahameng, ho kenya motlakase, ho hanyetsa kutu, ho hanyetsa mocheso o phahameng, ho thibela botsofali, joalo-joalo, 'me e lumellana hantle le tikoloho ebile ha e hlahise tšilafalo ea bobeli.Ka hona, ke sesebelisoa se secha sa ts'ireletso ea tikoloho e tala e sebetsang hantle haholo.
naha ea heso e thathamisitse fiber ea basalt e le e 'ngoe ea likhoele tse' nè tse kholo (carbon fiber, aramid fiber, ultra-high molecular weight polyethylene, basalt fiber) bakeng sa nts'etsopele ea bohlokoa.Litlhoko tsa bofofisi le masimo a mang li na le tebello e pharaletseng ea ts'ebeliso.
Mokhoa oa tlhahiso ea fiber ea basalt
Lejoe la tlhaho la basalt le entsoeng ke ho foqoha ha seretse se chesang le sebelisoa e le thepa e tala, e pshatlehileng le ho kenngoa ka sebōping se qhibilihang, se futhumatsoa ho fihlela boemong ba 1450 ~ 1500 ° C, 'me ka potlako le huloa ka terata ea platinum-rhodium alloy terata, le fiber ea basalt. e hlahiswa ka tsela ena.
Ka bokhutšoane, mokhoa oa ho etsa fiber ea basalt ke ho "hula" lejoe le thata la basalt le entsoeng ka silika mochesong o phahameng.
Bophara ba fiber ea basalt e hlahisoang ke theknoloji e teng e ka fihla ho 6 ~ 13μm, e leng mosesaane ho feta moriri.
Mokhoa oa eona oa tlhahiso o bontšoa setšoantšong se ka tlase.

E na le phallo e ntle ka samente le konkreite, matla a tlamang a matla, katoloso e tsitsitseng ea mocheso le ho koenya, le ho hanyetsa boemo ba leholimo bo botle.
Hygroscopicity e tlase
Hygroscopicity ea fiber ea basalt e ka tlase ho 0.1%, e tlase ho feta ea aramid fiber, rock wool le asbestos.
Boima bo tlase ba mocheso
Thermal conductivity ea basalt fiber ke 0.031 W/m·K -0.038 W/m·K, e ka tlase ho ea aramid fiber, aluminium silicate fiber, fiber ea khalase e se nang alkali, boea ba majoe, fiber ea silicon, fiber ea carbon le stainless tshepe.
Ha ho bapisoa le likhoele tse ling, fiber ea basalt e na le ts'ebetso e ntle haholo likarolong tse ngata.
