Kuchokera ku Smooth kupita ku "Micro-Pitted": Momwe Acid-Base Etching Imakwezera Ntchito ya Basalt Fiber

Acid-base yokhazikika basalt fiberndi chinthu chopangidwa mwapadera cha basalt fiber chokhala ndi thupi lapadera komanso Chemical katundu.

Kusintha kwa Surface Morphology

Kuwonjezeka kwa Micro-roughness

Pamwamba osatsatiridwa basalt fiber ndi yosalala. Komabe, pambuyo poti asidi-base etching, ulusi pamwamba amaonetsa maenje ting'onoting'ono ndi tokhala. Izi ndichifukwa choti ma acid-base solution amakhudzidwa ndi zinthu zomwe zili pamtunda, ndikusungunula zinthu zina.

Mwachitsanzo, kuyika kwa asidi kumatha kusungunula zitsulo monga calcium ndi magnesiamu pamwamba pa ulusi, pamene kuyika pansi kungayambitse dzimbiri kumagulu a silikoni, zomwe zimapangitsa kuti pakhale malo osagwirizana. Kuwonjezeka kumeneku kwa micro-roughness kumatha kukulitsa malo olumikizana pakati pa fiber ndi matrix zinthu monga resins.

Kusintha kwa Diameter

Nthawi zambiri, acid-base etching imachepetsa pang'ono m'mimba mwake basalt fiber. Izi ndichifukwa choti zinthu zina zomwe zili pamwamba pa ulusi zimasungunuka, zomwe zimapangitsa kuti ulusi wonse ukhale wotsika pang'ono. Komabe, kusintha kwa m'mimba mwake nthawi zambiri kumakhala kochepa ndipo kumatha kuyendetsedwa ndi kuwongolera zinthu monga nthawi ya etching komanso kuchuluka kwa asidi kapena maziko.

Kusintha kwa Chemical Composition

Kuchotsa Chidetso

Choyambirira ulusi wa basaltikhoza kukhala ndi mchere wina wosadetsedwa, monga iron oxides ndi aluminiyamu oxides. Acid-base etching imatha kuchotsa kapena kuchepetsa zomwe zili muzonyansazi. Mwachitsanzo, kutsekemera kwa asidi kumatha kusungunula zonyansa monga iron oxide, potero kumapangitsa kuti fiber ikhale yoyera. Izi ndizofunikira kwambiri pakukulitsa mawonekedwe akuthupi ndi mankhwala a ulusi, chifukwa kupezeka kwa zonyansa kumatha kukhudza zinthu monga mphamvu ya fiber ndi mphamvu. Kukaniza kwa Corrosion.

Kusintha kwa Element Ratio

Acid-base etching imasinthanso chiŵerengero cha zinthu mu ulusi wa basalt. Mwachitsanzo, pakupanga asidi, kuchuluka kwa zinthu za silicon kumatha kuwonjezeka chifukwa cha kusungunuka kwa zinthu zina zachitsulo; Chosiyanacho chikhoza kuchitika panthawi yopangira maziko. Kusintha kumeneku kwa chiŵerengero cha zinthu kumakhudza zinthu za fiber monga kukhazikika kwa mankhwala ndi kukhazikika kwa kutentha.

Kusintha Kwa Magwiridwe Athupi

Kusintha kwa Mphamvu

Acid-base etching imakhala ndi zovuta pamphamvu ya basalt fiber. Kumbali ina, kuchuluka kwamphamvu kwapamtunda ndi kuchotsa zonyansa kungathe, pamlingo wina, kukulitsa mphamvu yolumikizirana pakati pa ulusi ndi zinthu za matrix, zomwe zimapindulitsa pakuwongolera mphamvu zazinthu zophatikiza. Kumbali inayi, ngati kutchingira kuli kochulukira, zomwe zimabweretsa kuwonongeka kwakukulu kwa pamwamba kapena kuonda kwambiri, mphamvu yamkati ya ulusiwo imatha kuchepa. Chifukwa chake, njira yolumikizira imayenera kukonzedwa kuti igwirizane ndi mbali ziwiri izi.

Kuchita bwino kwa Adsorption

Chingwe chokhazikika cha fiber chimakhala ndi masamba omwe akugwira ntchito kwambiri, zomwe zimawonjezera magwiridwe ake adsorption. Mwachitsanzo, potsatsa matrix a utomoni, amatha kuphatikizana bwino ndi mamolekyu a utomoni kuti apange wosanjikiza wolimba kwambiri. Panthawi imodzimodziyo, pazovala zina zogwirira ntchito kapena zowonjezera, ulusi wokhazikika ungathenso kuwakomera bwino, potero kumapereka magwiridwe antchito kuzinthu zophatikizika.
