Calcium Chloride dihydrate ndiye othandizira kwambiri kutsitsa mtengo wa PH wa dziwe mu aquaculture.
Mtengo woyenera wa PH wa nyama zambiri zam'madzi m'mayiwe a aquaculture satenga nawo mbali amchere pang'ono (PH 7.0 ~ 8.5). Mtengo wa pH ukakhala wokwera kwambiri (PH≥9.5), umabweretsa zotsatira zoyipa monga kuchuluka pang'onopang'ono, kuchuluka kwa chakudya chokwanira komanso kuwonongeka kwa nyama zam'madzi. Chifukwa chake, momwe mungachepetsere phindu la PH yakhala njira yofunikira pakuwongolera mayendedwe amadzi amadziwe, komanso yakhala malo ofufuza otentha pakuwongolera kwamadzi. Hydrochloric Acid ndi Acetic Acid ndimagwiritsidwe ntchito a acid-base, omwe amatha kusokoneza ma ayoni a hydroxide m'madzi kuti achepetse mtengo wa PH. Calcium Chloride imachepetsa ayoni a hydroxide kudzera mu ayoni ya calcium, ndipo colloid yomwe imatulukayo imatha kuyenderera ndikuchepetsa ma phytoplankton, zomwe zimachepetsa kugwiritsidwa ntchito kwa kaboni dayokisaidi ndi ndere, potero kumatsitsa PH.
Pansipa pali kuyesa.
Kuyesaku kunali kafukufuku wokhudzana ndi zotsatira za Hydrochloric Acid, Calcium Chloride ndi Viniga woyera pochepetsa pH m'madzi amchere a 50L. Kuyesera kunali kafukufuku wokhudzana ndi zotsatira za hydrochloric acid, calcium chloride ndi viniga woyera pochepetsa pH m'madzi amadzimadzi 200 mL. Kuyesera kulikonse kunali ndi 1 gulu lolamulira lopanda kanthu ndi magulu azachipatala a 3 okhala ndimagulu osiyanasiyana, ndi magulu ofanana a 2 mgulu lirilonse. Patsiku lotentha, ikani madzi ofunikira pamalo otentha ndi mpweya wabwino panja, mulole kuti mukhale usiku umodzi umodzi ndikudikirira kuti mugwiritse ntchito tsiku lotsatira. Mtengo wa pH wa gulu lirilonse udapezeka isanayesedwe, ndi phindu la pH la gulu lirilonse Pakati pa kuyesayesa, nyengo ndi madzi omwewo ndi zina zimayambitsa kusintha kwa pH kusamuka pagulu lolamulira komanso gulu lazachipatala. Pofuna kuthandizira kuwunika kwa kuchepa kwa pH pagulu lazachipatala, mtengo wa PH udagwiritsidwa ntchito kuyimira kutsika kwa PH (△ PH = PH pagulu lolamulira - PH mgulu lazachipatala) poyeseraku. Pomaliza, zidziwitsozo zidasonkhanitsidwa ndikuwunika.
Zotsatira zoyeserera ndikuwunika zikuwonetsa kuti mulingo woyipa wa hydrochloric acid, calcium chloride dihydrate ndi viniga woyera amayenera kuchepetsa 1 pH unit pakuyesera anali 1.2 mmol / L, 1.5 g / L ndi 2.4 mL / L, motsatana. Mphamvu ya asidi ya hydrochloric pakuchepetsa pH idatenga pafupifupi 24 ~ 48 h, pomwe calcium chloride ndi vinyo wosasa zoyera zimatha kupitilira 72 ~ 96h. Mtengo wa PH wa dziwe la aquaculture ndiye wowongoleredwa bwino kwambiri ndi Calcium Chloride dihydrate.
Kachiwiri, Calcium Chloride mu aquaculture imathandizanso pakulimbitsa kuuma kwa madzi, kuwonongeka kwa poyizoni wa nitrite. Kashiamu mankhwala enaake amagwiritsidwa ntchito ngati kupopera mankhwala padziwe, ndikugwiritsa ntchito dziwe lamadzi pa mu mita mita imodzi ya madzi akuya 12-15kg. Mphamvu yake yothanizira tizilombo imakhudzidwa kwambiri ndi zomwe zili ndi pH m'madzi. Mphamvu ya bactericidal imalimbikitsidwa Kuphatikiza apo, Calcium Chloride 74% flake itha kugwiritsidwanso ntchito kudyetsa shrimp ndi nkhanu zowonjezerapo calcium kapena kudyetsa kuti muwonjezere.
Pomaliza, kodi njira yamchere ya Calcium Chloride kapena acid njira ya Calcium Chloride yomwe ingagwiritsidwe ntchito mu aquaculture? Ngakhale alkaline Calcium kapena Acid Calcium, bola ngati itha kutsatira mosamalitsa miyezo yaku China yopanga, momwe imagwiritsidwira ntchito ndiyomweyi, itha kugwiritsidwa ntchito pamakampani opanga nsomba.
