Los ntawm Smooth mus rau "Micro-Pitted": Yuav ua li cas Acid-Base Etching Txhim Kho Basalt Fiber Performance
Acid-base etched basalt fiberyog cov khoom siv fiber basalt tshwj xeeb uas tau kho nrog lub cev tshwj xeeb thiab Tshuaj lom neeg cov khoom.
Kev Hloov Pauv ntawm Qhov Chaw
Nce Micro-Roughness
Qhov saum npoo ntawm tsis kho basalt fiber yog qhov du heev. Txawm li cas los xij, tom qab acid-base etching, qhov saum npoo ntawm cov fiber ntau qhov me me thiab pob. Qhov no yog vim tias cov kua qaub-base tshuaj lom neeg nrog cov khoom siv hauv cov ntxhia ntawm qhov saum npoo ntawm cov fiber, xaiv cov tshuaj yaj.
Piv txwv li, acid etching tej zaum yuav yaj cov hlau sib xyaw xws li calcium thiab magnesium rau ntawm qhov chaw fiber, thaum lub hauv paus etching tej zaum yuav ua rau muaj qee qhov xeb rau cov sib xyaw silicon, ua rau qhov chaw tsis sib luag thiab ntxhib. Qhov kev nce ntxiv ntawm micro-roughness no tuaj yeem ua rau thaj chaw sib cuag ntawm cov fiber thiab cov ntaub ntawv matrix xws li resins loj dua.
Kev Hloov Pauv Txoj Kab uas hla
Feem ntau, acid-base etching me ntsis txo qhov txoj kab uas hla ntawm basalt fiberQhov no yog vim qee cov khoom siv ntawm qhov chaw fiber tau yaj, ua rau me ntsis txo qis hauv qhov loj ntawm cov fiber tag nrho. Txawm li cas los xij, qhov kev hloov pauv ntawm txoj kab uas hla no feem ntau me me thiab tuaj yeem tswj tau los ntawm kev tswj hwm cov yam xws li lub sijhawm etching thiab qhov concentration ntawm cov kua qaub lossis lub hauv paus.
Kev Hloov Pauv ntawm Cov Tshuaj Lom Zem
Kev Tshem Tawm Kev Ua Phem
Thawj cov fiber basalttej zaum yuav muaj qee cov zaub mov tsis huv, xws li hlau oxides thiab txhuas oxides. Acid-base etching tuaj yeem tshem tawm lossis txo cov ntsiab lus ntawm cov khoom tsis huv no. Piv txwv li, acid etching tuaj yeem yaj cov khoom tsis huv zoo li hlau oxide, yog li txhim kho qhov huv ntawm cov fiber. Qhov no yog qhov tseem ceeb rau kev txhim kho cov khoom siv lub cev thiab tshuaj ntawm cov fiber, vim tias qhov muaj cov khoom tsis huv yuav cuam tshuam rau cov khoom xws li lub zog fiber thiab Kev Tiv Thaiv Kev Xeb.
Kev Kho Qhov Sib Piv ntawm Cov Khoom
Kev kho acid-base etching kuj hloov pauv qhov piv ntawm cov ntsiab lus hauv cov fiber basalt. Piv txwv li, thaum lub sijhawm kho acid, cov ntsiab lus ntawm cov ntsiab lus silicon yuav nce ntxiv vim yog kev yaj ntawm qee cov ntsiab lus hlau; qhov xwm txheej rov qab yuav tshwm sim thaum lub sijhawm kho lub hauv paus. Qhov kev hloov pauv ntawm cov ntsiab lus no cuam tshuam rau cov khoom siv fiber xws li kev ruaj khov tshuaj lom neeg thiab kev ruaj khov thermal.
Kev Hloov Pauv ntawm Kev Ua Haujlwm Lub Cev
Kev Hloov Pauv Zog
Acid-base etching muaj ib qho kev cuam tshuam rau lub zog ntawm basalt fiber. Ntawm ib sab tes, qhov nce ntawm qhov roughness thiab tshem tawm cov impurities tuaj yeem, qee qhov, txhim kho lub zog sib txuas ntawm cov fiber 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 yog ntau dhau, ua rau muaj kev puas tsuaj loj heev lossis lub cheeb tsam nyias dhau, lub zog ntawm cov fiber nws tus kheej yuav txo qis. Yog li ntawd, cov txheej txheem etching yuav tsum tau ua kom zoo dua los sib npaug ob qho ntawm cov yam ntxwv no.
Kev Ua Haujlwm Zoo Dua ntawm Adsorption
Qhov saum npoo ntawm cov fiber etched muaj ntau qhov chaw nquag, uas ua rau nws cov kev ua tau zoo dua. Piv txwv li, thaum adsorbing ib lub matrix resin, nws tuaj yeem ua ke zoo dua nrog cov molecules resin los tsim ib txheej interfacial muaj zog dua. Tib lub sijhawm, rau qee cov txheej txheem ua haujlwm lossis cov khoom ntxiv, cov fiber etched kuj tuaj yeem adsorb lawv zoo dua, yog li muab ntau yam kev ua haujlwm rau cov khoom sib xyaw.
