Ongororo yezvidzidzo zvekugadzirisa pamusoro pebasalt fibers

Seyepamusoro-inoshanda inorganic fiber zvinhu, basalt fiber yakanakisa mechanical zvivakwa, Chemical kuramba, uye kugadzikana kwepamusoro-tembiricha kwakatungamira kune akasiyana maapplication muinjiniya yehurumende, composite zvinhu, uye kuchengetedza kwezvakatipoteredza. Nekudaro, basalt fibers ine nzvimbo yakatsetseka uye inoshaya anoshanda anoshanda mapoka, zvichikonzeresa kushomeka kwemukati mekubatana zvivakwa zvine matrix zvinhu. Naizvozvo, kugadziridzwa kwepamusoro kwebasalt fibers kunogona kuvandudza zvakanyanya hukama hwavo hwekubatanidza zvivakwa uye kuwedzera mashandisirwo avo mumisanganiswa uye minda yekuchengetedza nharaunda. Izvi zvinotevera kufambira mberi kwetsvakiridzo yenzira dzakati wandei dzekuchinja.

1. Silane coupling agent surface modification

Silane coupling agent inowanzoshandiswa pamusoro pekurapa mumiririri inonatsiridza hukama hwekubatana pakati pemafiber uye matrix zvinhu kuburikidza nemakemikari bonding.

KH-550 Kugadziriswa

Chidzidzo chacho chinoratidza kuti kurapa basalt fibers ne silane coupling agent KH-550 solution inoumba yakagadzikana kemikari zvisungo pafiber pamusoro uye inovandudza hukama hwepakati pakati pefiber neasphalt. Iyo inonzwisisika yeKH-550 ndeye 1.0%, uye nguva yekurapa ndeye 30 maminetsi. Mushure mekugadziriswa, kunamatira pakati pebasalt fiber uye asphalt kwakagadziridzwa negiredhi 1. Iko kunyura kwemafuta kwakawedzera ne65.5%, iyo yakanyanya kusimudzira kunamatira neasphalt.

KH-570 Kugadziridza

KH-570 inoshandura basalt fibers kuti iomese nzvimbo yavo uye kuwedzera mapoinzi anoshanda pane fiber pamusoro. Mune zvinyorwa zvakasanganiswa, pamwe nekuwedzera kwehurefu hwefiber yakagadziridzwa uye kuwanda kwekuwedzera, maitiro emagetsi ezvinyorwa zvinogadziriswa zvakanyanya kuvandudzwa.

2. Surfactant modification

CTAC kuchinja

Kupfekedzwa kwenyama yebasalt fibers ine cationic surfactant cetyltrimethylammonium chloride (CTAC) inovandudza hydrophilicity uye dispersibility yefiber mumvura. Iyi nzira yekushandura ine mhedzisiro yakakosha pane microbial film adhesion: iyo microbial adhesion simba inowedzera zvakanyanya. Kuwedzera huwandu hweiyo microbial inonamatira inofambisa application mukurapwa kwetsvina.

3. Organic iron liquid phase deposition modification

Iko kugadziridzwa kwebasalt fibers ne organic iron liquid phase deposition inogona kuvandudza bio-adhesion kugona kwefiber pamusoro uye kuwedzera kuwedzera kushandiswa kwayo mumunda wemarara ekurapa. Iyi nzira yekushandura inogona kuumba yakagadzikana iron oxide coating pamusoro pefiber kuti ivandudze adsorption yayo uye kushatisa kwezvinosvibisa.

4. Coating kugadziriswa ne nano-silica

Nanosilica particles dzakapararira zvakafanana mukupinda mukati kana kupararira, uye inogona kuva basalt fiber coating modification: pakati pebasalt fiber uye epoxy resin, nanosilica particles inoita basa rebhiriji, inovandudza zvikuru kuwirirana kwepakati pakati pezviviri. Mushure mekugadzirisa, kushata kwepamusoro kwebasalt fiber kunowedzera, nzvimbo chaiyo yepamusoro inowedzera, uye mapoka ekushanda ane oksijeni anowedzera. Chidzidzo chacho chakaratidza kuti nekushandiswa kwenanosilica-modified basalt fiber carrier: iyo chaiyo ye microbial film pa gram ye fiber yakawedzera ne 21.39%. Iko kusvibiswa kwekubvisa kushanda kwakagadziridzwa zvakanyanya.

Mhedziso uye Outlook

Basa repamusoro, interfacial bonding properties uye kushanda kwebasalt fibers zvakagadziriswa zvakanyanya nenzira dzakasiyana-siyana dzekugadzirisa nzvimbo. Pakati pavo:

1. silane coupling agent modification inonyanya kukodzera kuvandudza kusungirirwa kwebasalt fibers ine matrix zvinhu (eg simende, asphalt, epoxy resin, nezvimwewo).
2. Surfactant modification uye organic iron deposition modification yakanyatsokodzera nzvimbo yekuchengetedzwa kwezvakatipoteredza, kunyanya kune microbial carrier application mukurapwa kwetsvina.
3. Nano-silica coating modification, ine zvakanakira kuvandudza michina uye inoshanda zvivakwa, ine huwandu hwakasiyana hwetariro mumunda we Composite Materials uye kuchengetedza kwezvakatipoteredza.

Tsvagiridzo yeramangwana inogona kuwedzera kukwenenzvera maparamita ekugadzirisa uye kuongorora synergistic maitiro eakasiyana ekugadzirisa nzira kuti asangane nezvinodiwa zvekushandisa kwakasiyana.
