Ukuthelekiswa kwemiphumo yeendlela ezahlukeneyo zokuguqulwa kwiipropati zemishini ye-basalt fibers
1.Impembelelo yokuguqulwa kwe-agent ye-silane yokudibanisa kwiipropati zomatshini
I-Silane coupling agents (umzekelo, i-KH-550 kunye ne-KH-570) yenza i-coupling esebenzayo kumphezulu we-basalt fibers ngokusebenzisa. Ikhemikhali ukudibanisa, okuphucula ukudibanisa phakathi kweefayili kunye ne-substrate, kwaye ngexesha elifanayo, kunempembelelo ethile kwiimpawu zomatshini zemicu.
I-KH-550 ilungisiwe:
Izinto eziluncedo: yenza ibhondi yeekhemikhali kwi-fiber surface, kwaye uphucule ukunamathela phakathi kwefiber kunye ne-substrate, ngaphandle kokonakalisa kakhulu iipropati zomatshini wefiber ngokwayo.
Impembelelo: Uphononongo lubonisa ukuba emva kokuguqulwa kwe-KH-550, amandla okuqina kunye ne-modulus ye-elasticity ye-basalt fibers ayitshintshi ngokusisiseko, kodwa ngenxa yokuphuculwa kweempawu zokudibanisa i-interfacial, iipropathi ezipheleleyo zomatshini wezinto ezidibeneyo ziphuculwe kakhulu.
KH-570 uhlengahlengiso:
Izinto eziluncedo: I-KH-570 i-roughens umphezulu we-basalt fibers kwaye iphucula ukufakwa kwabo ngomatshini kunye ne-matrix.
Impembelelo: Ngelixa ukurhabaxa komphezulu kunokunciphisa kancinane ukomelela kweentsinga, ukomelela kukonke, ukuqina, kunye nokuqina komdibaniso kuphuculwe kakhulu ngenxa yeempawu eziphuculweyo zokudityaniswa kobuso.
2.Impembelelo yokuguqulwa kwe-surfactant kwiipropati zomatshini
I-Cationic surfactants (umzekelo, i-CTAC) zenza i-coating kumphezulu wefiber ikakhulu ngokusebenzisa i-adsorption ebonakalayo, kwaye eyona njongo yazo kukuphucula i-hydrophilicity kunye ne-dispersibility of fibers.
I-advanteji:Ukuguqulwa kwe-surfactant phantse akukho mpembelelo yokukhukuliseka kweekhemikhali kumphezulu wefayibha, ngoko ke inempembelelo encinci kwiipropati zomatshini wefiber.
Impembelelo: Amandla okuqina kunye ne-elastic modulus yefiber ayitshintshanga emva kokuguqulwa kwe-CTAC. Ukuguqulwa ngokukodwa kuphucula i-dispersibility kunye ne-hydrophilicity ye-fibers, ukwenzela ukuba izinto ze-matrix zibophe ngokulinganayo iifayili, ngaloo ndlela ziphucula ngokungathanga ngqo iipropati ze-mechanical of the composites.
3.Impembelelo ye-nano silica coating ukuguqulwa kwiipropati zomatshini
I-Nano-silica coating iphucula uburhabaxa bomphezulu kunye nobuchule bokubambisana phakathi kwe-fibers kunye ne-matrix ngokwenza uluhlu olufanayo lwe-nanoparticles ebusweni be-basalt fibers.
I-advanteji: Iinqununu ze-nano-silica zisebenza "njengebhuloho" kwi-fiber surface, ukuqinisa ukudibanisa phakathi kwefiber kunye ne-matrix.
Impembelelo:Ukugquma kwe-silica nanoparticles kunokubangela umonakalo omncinci womzimba kwi-fiber surface, kodwa impembelelo yayo kumandla obunzima bemicu incinci (ngokuqhelekileyo ingaphantsi kwe-5%). Emva kokuguqulwa, iimpawu ezipheleleyo zoomatshini (umzekelo, amandla okuqina, amandla okuguquguquka) kwezinto ezidibeneyo zingaphuculwa kakhulu, ukuya kuthi ga kwi-15% -30%.
4.Impembelelo ye-organic iron liquid isigaba sokuguqulwa kweempawu zomatshini
Indlela yokubekwa kwesigaba solwelo lwentsimbi ye-Organic isetyenziswa ikakhulu ukukhulisa isakhono sokubambelela kwi-bio-adhesion ye-basalt fibers, kunye nokwandiswa kwayo kweepropathi zoomatshini kungathanga ngqo.
I-advanteji: ukubunjwa kwengubo kunempembelelo encinci kwiipropati zomatshini wefiber, kwaye ngokukodwa kuphucula ukusebenza kwefiber.
Impembelelo:umaleko wokugquma unokunyusa kancinane ubungqongqo befiber, kodwa impembelelo kukuqina okanye ukuguquguquka kwamandla ayibalulekanga. Iipropathi zemishini yee-composites ezilungisiweyo zilinganiselwe, kwaye zihlala zisetyenziswa kwindawo yokukhusela indalo.
5.Impembelelo yolunye uhlengahlengiso lomzimba okanye lweekhemikhali kwiimpawu zomatshini
Iindlela zomzimba (umz. unyango lobushushu):
Ukunyangwa kobushushu kunokutshintsha ubume bomphezulu befiber, kodwa kunokubangela umonakalo oshushu kwifiber ngokwayo, okukhokelela ekuncipheni kokuqina kokuqina. Unyango olufanelekileyo lobushushu lunceda ukususa umaleko wokungcola kwifiber surface, ngaloo ndlela kuphuculwe ngokungathanga ngqo iipropathi zokudibanisa phakathi kwefiber kunye ne-matrix.
Ukulungiswa kweChemical etching:
Ukufakwa kweekhemikhali (umzekelo, unyango lwe-asidi) kwenza umphezulu wefiber ibe rhabaxa kwaye iphucula ukufakwa komatshini kujongano. Nangona kunjalo, i-etching inokuthi iyenze buthathaka ifayibha ngokwayo, ibangele ilahleko yeempawu zokuxinana, ekufuneka zilinganiswe.
