Kugwiritsa ntchito formic acid mu chikopa

Kugwiritsa ntchito kwaasidi formic mu chikopa

Chikopa ndi khungu lanyama lopangidwa ndi thupi komanso mankhwala monga kuchotsa tsitsi ndi kupukuta.Formic acid yakhala ikugwiritsidwa ntchito pamalumikizidwe osiyanasiyana monga kuchotsa tsitsi, kuwotcha, kukonza mitundu ndi kusintha kwa pH pakukonza zikopa. Ntchito yeniyeni ya formic acid pachikopa ndi motere:

1. Kuchotsa tsitsi

Formic acid amatha kufewetsa ubweya, ndikulimbikitsa kuwonongeka ndi kuchotsedwa kwa mapuloteni, omwe amathandiza kuyeretsa ndi kukonzanso kwachikopa.

2. Kupukuta

Powotcha zikopa,asidi formic angagwiritsidwe ntchito ngati neutralizing wothandizira kuthandiza wowotchera chikopa kuti azigwira ntchito yake mokwanira, potero kukonza kulimba ndi kufewa kwa chikopa.

3. Kuyika ndi kudaya

Pakuyika mitundu ndi kupaka utoto kwachikopa,asidi formic imathandizira utoto kulowa pachikopa ndikuwonjezera mphamvu yodaya, ndikuteteza chikopa kuti chisawonongeke ndi mamolekyu a utoto. Kugwiritsa ntchito mwanzeruasidi formic imatha kusintha mawonekedwe a chikopa ndikupangitsa kuti chikopacho chikhale chosalala komanso chowala.

4. Sinthani pH

Formic acid itha kugwiritsidwa ntchito kuwongolera pH pakukonza zikopa, zomwe zimachepetsa kukula kwa pore ndikuwonjezera kachulukidwe kachikopa, potero kumakulitsa kukana kwamadzi komanso kulimba. Nthawi zambiri, mtengo wa pH wa khungu lopanda khungu pambuyo pofewetsa desliming ndi 7.5 ~ 8.5, kuti khungu la imvi likhale loyenera kugwiritsira ntchito njira yochepetsera, ndikofunikira kusintha pH ya khungu lopanda kanthu, kuchepetsa mpaka 2.5 ~ 3.5, kotero kuti ndiyoyenera kuwotcha chrome. Njira yayikulu yosinthira pH mtengo ndi leaching ya asidi, yomwe imagwiritsa ntchito kwambiriasidi formic. Formic acid ali ndi mamolekyu ang'onoang'ono, olowera mwachangu, ndipo amakhala ndi masking pamadzi otenthetsera ma chrome, kotero kuti kulumikizana kwa njere zazing'ono zachikopa kumakhala bwino panthawi yofufuta. Nthawi zambiri amagwiritsidwa ntchito limodzi ndi sulfuric acid panthawi ya acid leaching.
