Uphononongo lwezifundo zokuguqulwa komphezulu we-basalt fibers

Njengomgangatho ophezulu wokusebenza kwe-inorganic fiber, i-basalt fiber igqwesile iipropathi zoomatshini, Ikhemikhali ukumelana, kunye nozinzo oluphezulu lobushushu kuye kwakhokelela kwizicelo ezahlukeneyo kubunjineli boluntu, izinto ezihlanganisiweyo, kunye nokhuseleko lokusingqongileyo. Nangona kunjalo, iifayibha ze-basalt zineendawo ezigudileyo kwaye zinqongophele amaqela asebenzayo asebenzayo, okukhokelela kwiipropathi ezihlwempuzekileyo ze-interfacial bonding kunye nezixhobo ze-matrix. Ngoko ke, ukuguqulwa komphezulu we-basalt fibers kunokuphucula kakhulu iipropati zabo zokubambisana kunye nokuphucula ukusetyenziswa kwazo kwii-composites kunye nemimandla yokukhusela indalo. Oku kulandelayo yinkqubela yophando yeendlela ezininzi zohlengahlengiso.

1. Silane coupling agent surface modification

I-agent yokudibanisa i-Silane yinto esetyenziswa ngokuqhelekileyo yonyango lomphezulu ophucula iimpawu zokudibanisa ubuso phakathi kweentsinga kunye nemathiriyeli ye-matrix ngokusebenzisa i-chemical bonding.

KH-550 Ukuguqulwa

Uphononongo lubonisa ukuba ukuphatha i-basalt fibers kunye ne-silane coupling agent KH-550 isisombululo senza izibophelelo zeekhemikhali ezizinzile kwi-fiber surface kunye nokuphucula ukudibanisa phakathi kwe-fiber kunye ne-asphalt. Uxinzelelo olufanelekileyo lwe-KH-550 yi-1.0%, kwaye ixesha lonyango yimizuzu engama-30. Emva kokuguqulwa, ukunamathela phakathi kwe-basalt fiber kunye ne-asphalt kwaphuculwa nge-1 grade. Izinga lokufunxa ioli liye landa nge-65.5%, ephucula kakhulu ukunamathela nge-asphalt.

KH-570 Ukuguqulwa

I-KH-570 iguqula i-basalt fibers ukuze idibanise ubuso bayo kwaye ikhulise amanqaku asebenzayo kwi-fiber surface. Kwizinto ezidibeneyo, kunye nokunyuka kobude befiber eguquliweyo kunye nomlinganiselo wokongezwa, iimpawu zemishini yezinto ezidibeneyo ziphuculwe kakhulu.

2. Ukuguqulwa kwe-surfactant

Ukuguqulwa kweCTAC

Ukugquma umzimba we-basalt fibers kunye ne-cationic surfactant cetyltrimethylammonium chloride (CTAC) iphucula i-hydrophilicity kunye ne-dispersibility ye-fibers emanzini. Le ndlela yokuguqula inempembelelo ebalulekileyo kwi-microbial film adhesion: amandla okubambelela kwi-microbial ayanda kakhulu. Ukwandisa ubungakanani be-microbial attachment iququzelela isicelo kunyango lwamanzi amdaka.

3. Ukuguqulwa kwesigaba sokubeka ulwelo lwentsimbi ephilayo

Ukuguqulwa kwemicu ye-basalt nge-organic iron liquid phase deposition inokuphucula i-bio-adhesion ye-fiber surface kunye nokuphucula ngakumbi ukusetyenziswa kwayo kwintsimi yonyango lwamanzi amdaka. Le ndlela yokuguqula inokwenza i-iron oxide egubungeleyo ezinzileyo kumphezulu wefiber ukuphucula i-adsorption yayo kunye nokuthotywa kwezinto ezingcolileyo.

4. Ukuguqulwa kwengubo nge-nano-silica

Iinqununu ze-Nanosilica zihlakazwe ngokufanayo kwi-infiltrant okanye i-dispersion, kwaye ingaba yi-basalt fiber yokuguqulwa kwe-coating: phakathi kwe-basalt fiber kunye ne-epoxy resin, i-nanosilica particles idlala indima yebhuloho, iphucula kakhulu ukuhambelana kwe-interfacial phakathi kwezi zibini. Emva kokuguqulwa, ubuninzi be-basalt fiber buyanda, indawo ethile yendawo iyanda, kwaye amaqela asebenzayo ane-oksijini ayanda. Uphononongo lubonise ukuba ngokusetyenziswa kwe-nanosilica-modified basalt fiber carrier: inani langempela lefilimu ye-microbial ngegram yefiber ephakanyisiweyo inyuke nge-21.39%. Ukusebenza kokususa ungcoliseko kuphuculwe kakhulu.

Ukuqukumbela kunye ne-Outlook

Umsebenzi ongaphezulu, iipropati ze-interfacial bonding kunye nokusebenza kwee-basalt fibers ziphuculwe kakhulu ngeendlela ezahlukeneyo zokuguqulwa kwendawo. Phakathi kwabo:

1. Ukuguqulwa kwe-agent yokudibanisa i-silane ilungele ngakumbi ekuphuculeni ukunamathela kwe-basalt fibers kunye nezixhobo ze-matrix (umzekelo, i-samente, i-asphalt, i-epoxy resin, njl.).
2. Ukuguqulwa kwe-surfactant kunye nokuguqulwa kwe-organic iron deposition ifaneleke ngakumbi kwintsimi yokukhusela indalo, ngakumbi kwi-microbial carrier application kunyango lwamanzi amdaka.
3. Ukuguqulwa kwe-Nano-silica coating, kunye neenzuzo zokuphucula iimpawu zoomatshini kunye nokusebenza, kunoluhlu olubanzi lwamathemba kwintsimi Izinto ezihlanganisiweyo kunye nokhuseleko lokusingqongileyo.

Uphando lwexesha elizayo lunokwandisa ngakumbi iiparamitha zenkqubo yokuguqulwa kunye nokuphonononga umphumo we-synergistic weendlela ezahlukeneyo zokuguqula ukuhlangabezana neemfuno zezicelo ezahlukeneyo.
