Ukubuyekezwa kwezifundo zokuguqulwa kobuso bezintambo ze-basalt

Njengezinto ze-fiber ezingaphili ezisebenza kahle kakhulu, izakhiwo ezinhle kakhulu ze-basalt fiber, Amakhemikhali ukumelana, kanye nokuqina kokushisa okuphezulu kuholele ekusetshenzisweni okuhlukahlukene kobunjiniyela bezokwakha, izinto ezihlanganisiwe, kanye nokuvikelwa kwemvelo. Kodwa-ke, imicu ye-basalt inezindawo ezibushelelezi futhi ayinawo amaqembu asebenzayo asebenzayo, okuholela ezicini zokubopha ezihlanganayo ngezinto ze-matrix. Ngakho-ke, ukuguqulwa kobuso bemicu ye-basalt kungathuthukisa kakhulu izakhiwo zayo zokubopha ezihlanganayo futhi kuthuthukise ukusetshenziswa kwazo ezinhlanganisweni nasezindaweni zokuvikela kwemvelo. Okulandelayo inqubekela phambili yocwaningo lwezindlela eziningana ezinkulu zokuguqula.

1. Ukuguqulwa kobuso be-ejenti yokuxhumanisa i-Silane

I-ejenti yokuhlanganisa i-Silane iyi-ejenti yokwelapha ubuso evame ukusetshenziswa ethuthukisa izakhiwo zokubopha phakathi kwezintambo nezinto ze-matrix ngokubopha kwamakhemikhali.

Ukuguqulwa kwe-KH-550

Ucwaningo lubonisa ukuthi ukwelapha imicu ye-basalt nge-silane coupling agent solution ye-KH-550 kwakha izibopho zamakhemikhali ezizinzile ebusweni be-fiber futhi kuthuthukisa ukubopha okuphakathi kwe-fiber ne-asphalt. Ukuhlushwa okufanelekile kwe-KH-550 kungu-1.0%, kanti isikhathi sokwelashwa siyimizuzu engama-30. Ngemva kokuguqulwa, ukunamathelana phakathi kwe-basalt fiber ne-asphalt kwathuthukiswa ngebanga eli-1. Izinga lokumuncwa kwamafutha landa ngo-65.5%, okwathuthukisa kakhulu ukunamathelana ne-asphalt.

KH-570 Ukuguqulwa

I-KH-570 iguqula imicu ye-basalt ukuze iqinise ubuso bayo futhi ikhulise amaphuzu asebenzayo ebusweni be-fiber. Entweni ehlanganisiwe, ngokwanda kobude be-fiber eguquliwe kanye nenani lokwengeza, izakhiwo zemishini zezinto ezihlanganisiwe zithuthukiswa kakhulu.

2. Ukuguqulwa kwe-surfactant

Ukuguqulwa kwe-CTAC

Ukumbozwa ngokomzimba kwemicu ye-basalt nge-cationic surfactant cetyltrimethylammonium chloride (CTAC) kuthuthukisa ukuguquguquka kwamanzi kanye nokuhlakazeka kwemicu emanzini. Le ndlela yokuguqula inomthelela omkhulu ekunamatheleni kwefilimu yama-microbial: amandla okunamathela kwama-microbial akhuliswa kakhulu. Ukwandisa inani lokunamathela kwama-microbial kwenza kube lula ukusetshenziswa ekuphathweni kwamanzi amdaka.

3. Ukuguqulwa kokufakwa kwesigaba soketshezi lwensimbi ye-organic

Ukuguqulwa kwemicu ye-basalt ngokufakwa kwesigaba soketshezi lwensimbi ephilayo kungathuthukisa ikhono lokunamathela kwe-bio ebusweni be-fiber futhi kuthuthukise ukusetshenziswa kwayo emkhakheni wokwelashwa kwamanzi amdaka. Le ndlela yokuguqula ingakha ungqimba lwe-iron oxide oluzinzile ebusweni be-fiber ukuze kuthuthukiswe ukumuncwa kwayo kanye nokuwohloka kokungcola.

4. Ukuguqulwa kokumboza yi-nano-silica

Izinhlayiya ze-nanosilica zihlakazeka ngokulinganayo ku-infiltrant noma ukuhlakazeka, futhi zingaguqulwa nge-basalt fiber coating: phakathi kwe-basalt fiber ne-epoxy resin, izinhlayiya ze-nanosilica zidlala indima yokuhlanganisa, zithuthukisa kakhulu ukuhambisana kwe-interfacial phakathi kwalezi ezimbili. Ngemva kokuguqulwa, ubulukhuni bomphezulu we-basalt fiber buyanda, indawo ethile yobuso iyanda, futhi amaqembu asebenzayo aqukethe umoya-mpilo ayanda. Ucwaningo lubonise ukuthi ngokusebenzisa i-nanosilica-modified basalt fiber carrier: inani langempela lefilimu yamagciwane ngegremu ngayinye ye-fiber efakiwe landa ngo-21.39%. Ukusebenza kahle kokususa ukungcola kuthuthukiswe kakhulu.

Isiphetho kanye Nombono

Umsebenzi wobuso, izakhiwo zokubopha phakathi kobuso kanye nokusebenza kwemicu ye-basalt kuthuthukiswe kakhulu ngezindlela ezahlukene zokuguqula ubuso. Phakathi kwazo:

1. Ukuguqulwa kwe-ejenti yokuhlanganisa i-silane kufaneleka kakhulu ekuthuthukiseni ukunamathela kwezintambo ze-basalt ngezinto ze-matrix (isb. usimende, i-asphalt, i-epoxy resin, njll.).
2. Ukuguqulwa kwe-surfactant kanye nokuguqulwa kwe-organic iron deposition kufaneleka kakhulu emkhakheni wokuvikela imvelo, ikakhulukazi ekusetshenzisweni kokuthwala amagciwane ekuhlanzweni kwendle.
3. Ukuguqulwa kwengubo ye-nano-silica, kanye nezinzuzo zokuthuthukisa izakhiwo zemishini nezokusebenza, kunezindlela eziningi zokuthola amathuba emkhakheni we- Izinto Ezihlanganisiwe kanye nokuvikelwa kwemvelo.

Ucwaningo lwesikhathi esizayo lungathuthukisa kakhulu imingcele yenqubo yokuguqula futhi luhlole umphumela wokubambisana kwezindlela ezahlukene zokuguqula ukuze kuhlangatshezwane nezidingo zezinhlelo zokusebenza ezahlukene.
