Basa reBasalt Fiber Impregnants
Kushandiswa kwemishonga inopinza ganda ndiyo imwe yenzira dzakajairika uye dzinoshanda dzekurapa machira ekudzivirira ganda mukugadzirwa kwe Basalt Fibers. Basa rinoitwa nechinhu chinopinda mukugadzira fiber yebasalt uye kugadzira fiber composite riri munzvimbo ina dzinotevera.
(1) Kuzora mafuta, basa rekudzivirira
Basalt faibha Chinhu chinopinza mumafuta chinogona kuzadza mukaha uri pakati pemafiber, kuumbwa kwemafuta anozora, uye kuderedza coefficient yekukweshana kwefiber. Nokudaro, mafuta anozora anogona kushandiswa mukugadzirisa fiber yebasalt kuderedza kupera kwefiber yepakutanga uye kuchengetedza simba rakakwirira, ukuwo achideredza kusagadzikana kusina kuenzana kunokonzerwa nechiitiko chekutanga chekutyoka kwebvudzi refilament, kusangana nezvinodiwa zvekudhonza uye zvinotevera zvemabundles estranded, short cut, textile, nezvimwe, zvakaita se coating nanoparticle modified infiltration agent inogona kuwedzera basalt fiber bundling, uye nokudaro inovandudza simba rekutyoka kwefiber. Pamusoro pezvo, coated basalt fiber infiltant inogona kupa layer yekudzivirira fiber yebasalt, kudzivirira zvinhu zvinoparadza zvekunze kana nzvimbo inopisa zvakanyanya pamigumisiro yakaipa yefiber yebasalt.
(2) Kubatana, mhedzisiro yekuunganidza
Chinhu chinoisa pamuviri muchikamu chekubatanidza chinogona kuva nekubatana kwemonofilament yebasalt fiber inopfuura imwe chete muboka resiriki yekutanga, kudzivirira kushushikana kwemonofilament shoma inokonzerwa nekupararira kwechiitiko chesiriki nesiriki, asiwo chinogona kudzivirira zvinobudirira chiitiko chekucheka kwefayibha yakavhurika yeshinda, kuve nechokwadi chekuti fiber bundle iri kushanda zvakanaka. Saka, mukucheka kwepfupi, yakafukidzwa nechinhu chinopinza chepolyurethane chinogona kuwedzera kuchinjika uye kuramba kwesimba kwebasalt fiber composites, izvo zvinogona kudzivirira zvinobudirira kuitika kwekuputika kwefayibha yebasalt uye chiitiko chesiriki chakareruka.
(3) Kuvandudza kuenderana kwekubatana pakati pebasalt fiber nezvinhu zvematrix
Mushonga unopinza unogona kuita kuti zvinhu zvebasalt fiber uye matrixsanganisa muchimiro che Kemikari zvisungo, uye zvinosimudzira simba rekubatanidza pakati pema "interfacial bonding force", izvo zvinovandudza mashandiro ese e "basalt fiber composites". Yakafukidzwa ne "polyethylene-type infiltrant" inogona kuvandudza kuenderana kwekubatana pakati pe "basalt fibers" nezvinhu zvematrix, uye "fiber-reinforced polyethylene resin composites" yakagadzirwa ne "infilted basalt fibers" yakawedzera simba re "tensile" uye "tensile modulus" ne20%-40% uye 15%-20%, zvichiteerana, zvichienzaniswa neyakanga isati yagadziriswa.
(4) Ita kuti basalt fiber ive nekushanda kwakaringana pakugadzirisa
Kuputira chinhu chinopinda mukati mechinhu kunogona kuita kuti pamusoro pefiber pave panyoro, kunatsiridza pamusoro payo, uye kubatsira kuvandudza kuumbwa kwayo. faibha yebasalt kuitira kuti zvive nyore kuumba chimiro nehukuru hunodiwa, kuwedzera kuchinjika kwekugadzirisa, kusangana nekuwedzera kwekugadzirisa nekushandisa fiber dzebasalt zvinodiwa pakugadzirisa kupfupika, tepi, kupararira, antistatic, uye tensile. Kuburikidza nekuyedza kwekudhonza, zvinogona kuonekwa kuti simba rekudhonza rebasalt fiber rakawedzera kubva pa1146.06 MPa kusvika pa2115.80 MPa mushure mekuputira nemushonga unopinza, iyo iri 84.62% yakakwira kupfuura yefiber yekutanga.
