Ukubuyekezwa kwezifundo zokuguqulwa kwendawo ye-basalt fibers

Njengento ephezulu yokusebenza kwe-inorganic fiber, izakhiwo ezinhle kakhulu zemishini ye-basalt fiber, Amakhemikhali ukumelana, kanye nokuzinza kwezinga lokushisa eliphezulu kuye kwaholela ekusetshenzisweni okuhlukahlukene kwezobunjiniyela bomphakathi, izinto eziyinhlanganisela, nokuvikelwa kwemvelo. Kodwa-ke, imicu ye-basalt inezindawo ezibushelelezi futhi ayinamaqembu asebenzayo asebenzayo, okuholela emazingeni ampofu wokuhlangana okuhlanganayo ngezinto ze-matrix. Ngakho-ke, ukuguqulwa okungaphezulu kwezintambo ze-basalt kungathuthukisa kakhulu izakhiwo zabo zokuhlanganisa ubuso obuphakathi futhi kuthuthukise ukusetshenziswa kwazo ezinkombeni nasezinkundleni zokuvikela imvelo. Okulandelayo yinqubekelaphambili yocwaningo yezindlela ezimbalwa ezinkulu zokuguqula.

1. I-Silane coupling agent surface ukuguqulwa

I-ejenti yokuhlanganisa i-Silane iyi-ejenti yokwelapha engaphezulu evame ukusetshenziswa ethuthukisa izakhiwo zokuhlanganisa ubuso phakathi kwamafayibha nezinto ze-matrix ngokusebenzisa isibopho samakhemikhali.

KH-550 Ukuguqulwa

Ucwaningo lubonisa ukuthi ukwelapha i-basalt fibers nge-silane coupling agent KH-550 isisombululo sakha izibopho zamakhemikhali ezinzile endaweni ye-fiber futhi kuthuthukisa ukuhlangana phakathi kobuso phakathi kwe-fiber ne-asphalt. Ukuhlushwa okunengqondo kwe-KH-550 ngu-1.0%, futhi isikhathi sokwelashwa imizuzu engama-30. Ngemuva kokuguqulwa, ukunamathela phakathi kwe-basalt fiber ne-asphalt kwathuthukiswa ngebanga elingu-1. Izinga lokumunca uwoyela lenyuke ngo-65.5%, okuthuthukise kakhulu ukunamathela ngetiyela.

KH-570 Ukuguqulwa

I-KH-570 ilungisa imicu ye-basalt ukuze iqine futhi ikhulise amaphuzu asebenzayo endaweni yefayibha. Ezingxenyeni ezihlanganisiwe, ngokwanda kobude be-fiber eguquliwe kanye nenani lokwengeza, izakhiwo zemishini yezinto ezihlanganisiwe zithuthukiswa kakhulu.

2. Ukuguqulwa kwe-surfactant

Ukushintsha kwe-CTAC

Ukumbozwa okungokomzimba kwemicu ye-basalt ene-cationic surfactant cetyltrimethylammonium chloride (CTAC) kuthuthukisa i-hydrophilicity kanye nokuhlakazeka kwemicu emanzini. Le ndlela yokuguqula inomphumela ophawulekayo ekunamatheleni kwefilimu ye-microbial: amandla okunamathela amancane akhuphuka kakhulu. Ukwandisa inani lokunamathiselwe kwe-microbial kusiza isicelo ekuhlanzeni amanzi angcolile.

3. Ukuguqulwa kwesigaba sokubeka uketshezi lwensimbi ye-organic

Ukuguqulwa kwemicu ye-basalt ngokufakwa kwesigaba se-organic iron liquid kungathuthukisa ikhono le-bio-adhesion le-fiber surface futhi kuthuthukise ukusetshenziswa kwayo emkhakheni wokuhlanza amanzi angcolile. Le ndlela yokuguqula ingenza ukunamathela okuzinzile kwe-iron oxide ebusweni bomucu ukuze kuthuthukiswe ukukhanga kwayo kanye nokucekelwa phansi kwezinto ezingcolisayo.

4. Ukuguqulwa kwe-coating nge-nano-silica

Izinhlayiya ze-Nanosilica zihlakazeka ngokulinganayo ku-infiltrant noma ukuhlakazwa, futhi kungaba ukuguqulwa kwe-basalt fiber coating: phakathi kwe-basalt fiber ne-epoxy resin, izinhlayiya ze-nanosilica zidlala indima yebhuloho, zithuthukisa kakhulu ukuhambisana kobuso phakathi kokubili. Ngemuva kokuguqulwa, ukuqina kwe-basalt fiber kuyanda, indawo ethize iyanda, futhi amaqembu asebenzayo aqukethe umoya-mpilo ayanda. Ucwaningo lubonise ukuthi ngokusetshenziswa kwe-nanosilica-modified basalt fiber carrier: inani langempela lefilimu ye-microbial ngegramu ye-fiber efakwe ku-21.39%. Ukusebenza kahle kokususa ukungcola kwaba ngcono kakhulu.

Isiphetho kanye ne-Outlook

Umsebenzi ongaphezulu, izakhiwo zokuhlanganisa ubuso obuphakathi kanye nokusebenza kwemicu ye-basalt kwathuthukiswa kakhulu ngezindlela ezihlukene zokuguqulwa kwendawo. Phakathi kwazo:

1. ukuguqulwa kwe-ejenti yokuhlanganisa i-silane kulungele kangcono ukuthuthukisa ukunamathela kwemicu ye-basalt ngezinto ze-matrix (isb. usimende, itiyela, i-epoxy resin, njll.).
2. Ukuguqulwa kwe-surfactant kanye nokuguqulwa kwe-organic iron deposition kuyifanele kakhulu inkambu yokuvikela imvelo, ikakhulukazi ekufakweni kwe-microbial carrier ekuhlanzeni indle.
3. Ukuguqulwa kwe-nano-silica coating, ngezinzuzo zokuthuthukisa izakhiwo zemishini nokusebenza, kunezinhlobonhlobo zamathemba emkhakheni we Izinto Ezihlanganisiwe kanye nokuvikelwa kwemvelo.

Ucwaningo lwesikhathi esizayo lungathuthukisa futhi imingcele yenqubo yokuguqulwa futhi luhlole umthelela we-synergistic wezindlela ezihlukene zokulungisa ukuze kuhlangatshezwane nezidingo zezinhlelo zokusebenza ezahlukene.
