Kuenzanisa kwemigumisiro yemaitiro akasiyana-siyana ekugadzirisa pamagetsi emagetsi ebasalt fibers
1.Effect ye silane coupling agent kugadziriswa pane mechanical properties
Silane coupling agents (semuenzaniso, KH-550 uye KH-570) inogadzira reactive coating pamusoro pebasalt fibers kuburikidza. Chemical bonding, iyo inovandudza hukama hwepakati pakati pefibers uye substrate, uye panguva imwechete, ine humwe hunoita pamagetsi emagetsi.
KH-550 Yakagadziriswa:
Zvakanakira: gadzira chisungo chemakemikari pane fiber pamusoro, uye uvandudze kusungirirwa pakati pefiber uye substrate, pasina kukuvadza zvakanyanya maitiro emagetsi efiber pachayo.
Impact: Zvidzidzo zvinoratidza kuti mushure mekushandurwa kweKH-550, simba rekusimba uye modulus ye elasticity yebasalt fibers inoramba isingachinji, asi nekuda kwekuvandudzwa kweiyo interfacial bonding properties, iyo yese mechanical properties yecomposite zvinhu inovandudzwa zvakanyanya.
KH-570 shanduko:
Zvakanakira: KH-570 inoshatisa pamusoro pebasalt fibers uye inosimudzira yavo yekumisikidza yekumisikidza nematrix.
Impact: Nepo kukwasharara kwepamusoro kungadzikisira zvishoma kusimba kwesimba remafayibha, simba rose, kusimba, uye kusimba kwemusanganiswa kunovandudzwa zvakanyanya nekuda kwekuvandudzwa kwehukama hwekubatana.
2.Effect ye surfactant modification pa mechanical properties
Cationic surfactants (eg CTAC) inogadzira jira pafiber pamusoro kunyanya kuburikidza nekushambadza kwemuviri, uye chinangwa chavo chikuru ndechekuvandudza hydrophilicity uye dispersibility yefiber.
Advantage:Iyo surfactant gadziriso ine inenge isina kemikari erosion athari pafiber pamusoro, saka haina mhedzisiro pamichina ye fiber.
Impact: Iyo yakasimba simba uye elastic modulus yefiber haina kuchinjika mushure mekushandurwa kweCTAC. Iko kushandurwa kunonyanya kuvandudza dispersibility uye hydrophilicity yefibers, kuitira kuti matrix zvinhu zvakafanana zvinoputira fiber, nokudaro zvisina kunanga kunatsiridza mashandiro emagetsi ezviumbwa.
3.Effect ye nano silica coating modification pane mechanical properties
Nano-silica coating inovandudza kushata kwepamusoro uye kugona kwekubatana kwemukati pakati pemafiber uye matrix nekugadzira yunifomu layer ye nanoparticles pamusoro pebasalt fibers.
Advantage: Iyo nano-silica particles inoshanda se "bhiriji" pafiber pamusoro, kusimbisa hukama pakati pefiber uye matrix.
Impact:Iko kupfekedzwa kwesilica nanoparticles kunogona kukonzera kukuvadzwa kwemuviri kudiki kune fiber pamusoro, asi kukanganisa kwayo pakusimba kwesimba remafibhi idiki (kazhinji isingasviki 5%). Mushure mekugadziridzwa, iyo yakazara ma mechanical properties (eg tensile simba, flexural simba) yezvakaumbwa zvinhu zvinogona kuvandudzwa zvakanyanya, kusvika 15% -30%.
4.Effect ye organic iron liquid phase deposition modification pane mechanical properties
Organic iron liquid chikamu deposition nzira inonyanya kushandiswa kusimudzira bio-adhesion kugona kwebasalt fibers, uye kukwidziridzwa kwayo kwemakanika zvimiro hakuna kunanga.
Advantage: kuumbwa kwekuputira kune zvishoma zvishoma pamagetsi emagetsi efiber, uye kunyanya kunowedzera kushanda kwefiber.
Impact:iyo yekuputira layer inogona kuwedzera zvishoma kuomarara kwefiber, asi kukanganisa pakusimba kana kushanduka kwesimba hakuna kukosha. Iwo emakanika zvimiro zveakagadziridzwa macomposites ane mashoma, uye anowanzo shandiswa munharaunda yekuchengetedzwa kwezvakatipoteredza.
5.Effect yezvimwe zvemuviri kana kemikari kugadziriswa pamagetsi emagetsi
Nzira dzemuviri (semuenzaniso kurapwa kupisa):
Kurapa kwekupisa kunogona kushandura chimiro chepamusoro chefiber, asi chinogona kukonzera kukuvadza kwemafuta kune fiber pachayo, zvichikonzera kudzikira kwesimba rekusimba. Kurapa kwakakodzera kwekupisa kunobatsira kubvisa tsvina yekusachena pamusoro pefiber pamusoro, nokudaro nenzira isina kunanga kuvandudza hukama hwekubatana pakati pefiber uye matrix.
Chemical etching shanduko:
Kemikari etching (semuenzaniso, kurapwa kweasidhi) inoshatisa iyo fiber pamusoro uye inosimudzira iyo mechanic kunyudzwa kweiyo interface. Nekudaro, etching inogona kunetesa iyo fiber pachayo, zvichikonzera kurasikirwa kwemaitiro ekusimba, ayo anoda kuyerwa.
