Los ntawm du mus rau "Micro-Pitted": Yuav Ua Li Cas Acid-Base Etching Upgrades Basalt Fiber Performance

Acid-base etched basalt fiber ntauyog ib qho tshwj xeeb kho basalt fiber ntau nrog lub cev tshwj xeeb thiab Tshuaj khoom.

Kev hloov ntawm Surface Morphology

Nce Micro-Roughness

Qhov saum npoo tsis kho basalt fiber ntau yog tus du. Txawm li cas los xij, tom qab acid-base etching, fiber ntau nthuav tawm ntau qhov me me thiab pob. Qhov no yog vim hais tias cov kua qaub-raws li kev daws teeb meem tshuaj lom neeg nrog cov ntxhia hauv cov khoom siv fiber ntau, xaiv cov tshuaj tua kab mob.

Piv txwv li, acid etching tej zaum yuav nyiam yaj hlau tebchaw xws li calcium thiab magnesium nyob rau hauv fiber ntau nto, thaum lub hauv paus etching yuav ua rau ib tug degree ntawm corrosion rau silicon tebchaw, ua rau ib tug tsis sib xws, ntxhib nto. Qhov kev nce hauv micro-roughness tuaj yeem ua kom qhov chaw sib txuas ntawm fiber ntau thiab matrix cov ntaub ntawv zoo li resins.

Txoj kab uas hla hloov

Feem ntau, acid-base etching me ntsis txo txoj kab uas hla ntawm lub basalt fiber ntau. Qhov no yog vim qee yam khoom ntawm fiber ntau yaj, ua rau me ntsis txo qis hauv qhov loj ntawm fiber ntau. Txawm li cas los xij, qhov kev hloov pauv no feem ntau me me thiab tuaj yeem tswj hwm los ntawm kev tswj hwm yam xws li lub sij hawm etching thiab cov concentration ntawm cov kua qaub los yog hauv paus.

Kev hloov tshuaj lom neeg

Kev tshem tawm impurity

Keeb kwm basalt fiberstej zaum yuav muaj ib co impurity minerals, xws li hlau oxides thiab txhuas oxides. Acid-base etching tuaj yeem tshem tawm lossis txo cov ntsiab lus ntawm cov impurities. Piv txwv li, acid etching tuaj yeem yaj cov impurities zoo li hlau oxide, yog li txhim kho cov purity ntawm fiber ntau. Qhov no yog qhov tseem ceeb rau kev txhim kho lub cev thiab tshuaj lom neeg ntawm fiber ntau, vim tias muaj cov impurities tuaj yeem cuam tshuam cov khoom xws li fiber ntau thiab Corrosion Resistance.

Element Ratio Kho

Acid-base etching kuj hloov qhov piv ntawm cov ntsiab lus hauv basalt fiber. Piv txwv li, thaum lub sij hawm acid etching, cov ntsiab lus txheeb ze ntawm silicon cov ntsiab lus yuav nce vim qhov kev sib cais ntawm qee cov hlau; qhov teeb meem sib txawv yuav tshwm sim thaum lub hauv paus etching. Qhov kev hloov pauv hauv qhov piv txwv no cuam tshuam rau cov khoom fiber ntau xws li tshuaj lom neeg ruaj khov thiab thermal stability.

Kev hloov pauv ntawm lub cev

Lub zog hloov

Acid-base etching muaj kev cuam tshuam rau lub zog ntawm basalt fiber ntau. Ntawm ib sab, qhov nce ntawm qhov roughness thiab tshem tawm ntawm impurities tuaj yeem, rau qee qhov, txhim khu kev sib txuas ntawm lub zog ntawm cov fiber ntau thiab cov khoom siv matrix, uas yog qhov zoo rau kev txhim kho lub zog ntawm cov khoom sib xyaw. Ntawm qhov tod tes, yog tias qhov etching ntau dhau, ua rau muaj kev puas tsuaj loj heev los yog ib txoj kab uas hla dhau, lub zog ntawm cov fibers nws tus kheej yuav txo qis. Yog li ntawd, cov txheej txheem etching yuav tsum tau kho kom zoo kom sib npaug ntawm ob qho kev cuam tshuam.

Txhim khu kev ua tau zoo adsorption

Lub etched fiber nto muaj ntau qhov chaw ua haujlwm, uas txhim kho nws cov kev ua haujlwm adsorption. Piv txwv li, thaum adsorbing ib resin matrix, nws tuaj yeem ua ke zoo dua nrog cov roj molecules los tsim cov txheej txheej interfacial muaj zog. Nyob rau tib lub sijhawm, rau qee cov txheej txheem ua haujlwm lossis cov khoom siv ntxiv, cov etched fiber ntau kuj tuaj yeem ua rau lawv zoo dua, yog li muab kev ua haujlwm ntau dua rau cov khoom sib xyaw.
