Uphononongo lwezifundo zokuguqulwa komphezulu weefayibha zebasalt

Njengempahla yefayibha ye-inorganic esebenza kakuhle, iipropati ezintle kakhulu zoomatshini ze-basalt fiber, Ikhemikhali ukumelana, kunye nokuzinza kobushushu obuphezulu kukhokelele kwizicelo ezahlukeneyo kubunjineli bezakhiwo, izixhobo ezidityanisiweyo, kunye nokukhuselwa kwendalo. Nangona kunjalo, iifayibha ze-basalt zinomphezulu ogudileyo kwaye azinamaqela asebenzayo asebenzayo, nto leyo ebangela ukuba iipropati zokubopha phakathi kwe-interfacial zingasebenzi kakuhle ngezinto ze-matrix. Ke ngoko, ukuguqulwa komphezulu weefayibha ze-basalt kunokuphucula kakhulu iipropati zazo zokubopha phakathi kwe-interfacial kwaye kuphucule ukusetyenziswa kwazo kwiindawo ezidityanisiweyo kunye nokukhuselwa kwendalo. Oku kulandelayo yinkqubela phambili yophando lweendlela ezininzi eziphambili zokuguqula.

1. Ukuguqulwa komphezulu wearhente yokudibanisa i-Silane

I-arhente yokudibanisa i-Silane yiarhente yonyango lomphezulu esetyenziswa rhoqo ephucula iipropati zokubopha phakathi kweefayibha kunye nezinto ze-matrix ngokusebenzisa ukubopha ngeekhemikhali.

Uhlengahlengiso lwe-KH-550

Olu phononongo lubonisa ukuba ukunyanga iifayibha zebasalt nge-silane coupling agent isisombululo se-KH-550 kwenza iibhondi zeekhemikhali ezizinzileyo kumphezulu wefayibha kwaye kuphucula ukubopha phakathi kwefayibha kunye ne-asphalt. Uxinzelelo olufanelekileyo lwe-KH-550 yi-1.0%, kwaye ixesha lonyango yimizuzu engama-30. Emva kokuguqulwa, ukunamathelana phakathi kwefayibha yebasalt kunye ne-asphalt kuphuculwe nge-1 grade. Izinga lokufunxwa kweoyile lenyuke ngama-65.5%, nto leyo eyaphucula kakhulu ukunamathelana ne-asphalt.

KH-570 Uhlengahlengiso

I-KH-570 iguqula imicu ye-basalt ukuze irhawuze umphezulu wayo kwaye yonyuse amanqaku asebenzayo kumphezulu wefayibha. Kwizinto ezidityanisiweyo, ngokonyuka kobude befayibha eguquliweyo kunye nobungakanani bokongeza, iipropati zoomatshini zezinto ezidityanisiweyo ziphucuka kakhulu.

2. Ukuguqulwa kwe-Surfactant

Uhlengahlengiso lwe-CTAC

Ukugqunywa ngokwasemzimbeni kweefayibha zebasalt nge-cationic surfactant cetyltrimethylammonium chloride (CTAC) kuphucula ukunamathela kwamanzi kunye nokusasazeka kweefayibha emanzini. Le ndlela yokuguqula inefuthe elikhulu ekunamatheleni kwefilimu yeentsholongwane: amandla okunamathela kweentsholongwane ayanda kakhulu. Ukwandisa ubungakanani bokunamathela kweentsholongwane kwenza kube lula ukusetyenziswa kunyango lwamanzi amdaka.

3. Uhlengahlengiso lokufakwa kwesigaba solwelo lwentsimbi yendalo

Ukuguqulwa kweefayibha zebasalt ngokufakwa kwe-organic iron liquid phase kunokuphucula amandla okunamathela kwi-bio kumphezulu wefayibha kwaye kuphucule ngakumbi ukusetyenziswa kwayo kwicandelo lokunyanga amanzi amdaka. Le ndlela yokuguqula ingenza i-iron oxide coating eqinileyo kumphezulu wefayibha ukuphucula ukufunxwa kwayo kunye nokonakala kwezinto ezingcolisayo.

4. Ukuguqulwa kwengubo yi-nano-silica

Iinxalenye zeNanosilica zisasazwa ngokulinganayo kwindawo engena ngaphakathi okanye esasazekayo, kwaye zingaguqulwa zibe yi-basalt fiber coating: phakathi kwe-basalt fiber kunye ne-epoxy resin, iinxalenye ze-nanosilica zidlala indima yokudibanisa, ziphucula kakhulu ukuhambelana phakathi kwezi zimbini. Emva kokuguqulwa, uburhabaxa bomphezulu we-basalt fiber buyanda, indawo ethile yomphezulu iyanda, kwaye amaqela asebenzayo aqulethe ioksijini ayanda. Olu phononongo lubonise ukuba ngokusebenzisa i-nanosilica-modified basalt fiber carrier: inani langempela lefilimu ye-microbial ngegram yefayibha efakweyo landa nge-21.39%. Ukusebenza kakuhle kokususa ungcoliseko kuphuculwe kakhulu.

Isiphelo kunye neMbono

Umsebenzi womphezulu, iipropati zokubopha phakathi kobuso kunye nokusebenza kweefayibha zebasalt ziphuculwe kakhulu ngeendlela ezahlukeneyo zokuguqula umphezulu. Phakathi kwazo:

1. Ukuguqulwa kwe-silane coupling agent kulungele ngakumbi ukuphucula ukunamathelana kwee-basalt fibers ngezinto ze-matrix (umz. isamente, i-asphalt, i-epoxy resin, njl.njl.).
2. Ukuguqulwa kwe-surfactant kunye nokuguqulwa kwe-organic iron deposition zilungele ngakumbi intsimi yokukhusela okusingqongileyo, ngakumbi ukusetyenziswa kwe-microbial carrier ekunyangweni kwamanzi amdaka.
3. Ukuguqulwa kwengubo ye-nano-silica, kunye neenzuzo zokuphucula iipropati zoomatshini kunye nokusebenza, kunoluhlu olubanzi lwamathemba kwicandelo le Izinto ezidityanisiweyo kunye nokukhuselwa kokusingqongileyo.

Uphando lwexesha elizayo lunokuphucula ngakumbi iiparameter zenkqubo yokuguqula kwaye luhlolisise isiphumo sokusebenzisana kweendlela ezahlukeneyo zokuguqula ukuhlangabezana neemfuno zezicelo ezahlukeneyo.
