Phosphoric Acid 85% Yaulimi

Phosphoric acid, yomwe imadziwikanso kuti orthophosphoric acid, ndi asidi omwe amagwiritsidwa ntchito m'mafakitale osiyanasiyana. Ili ndi acidity yolimba kwambiri, mankhwala ake ndi H3PO4, ndipo molekyulu yake ndi 97.995. Mosiyana ndi zidulo zina zosasunthika, phosphoric acid ndi yokhazikika ndipo sichiwonongeka mosavuta, ndikupangitsa kukhala chisankho chodalirika pa ntchito zosiyanasiyana. Ngakhale kuti asidi wa phosphoric sali wamphamvu monga hydrochloric, sulfuric, kapena nitric acids, ndi wamphamvu kuposa acetic ndi boric acid. Kuphatikiza apo, asidiyu ali ndi zinthu zambiri za asidi ndipo amachita ngati tribasic acid yofooka. Ndizofunikira kudziwa kuti phosphoric acid ndi hygroscopic ndipo imatenga chinyezi kuchokera mumlengalenga. Kuphatikiza apo, imatha kusintha kukhala pyrophosphoric acid ikatenthedwa, ndipo kutayika kwamadzi kotsatira kumatha kusintha kukhala metaphosphoric acid.

Kugwiritsa ntchito

Kusinthasintha kwa phosphoric acid kumapangitsa kuti ikhale yofunika kwambiri m'mafakitale osiyanasiyana, makamaka opanga mankhwala, chakudya ndi feteleza. M'munda wamankhwala, amagwiritsidwa ntchito kwambiri ngati anti- dzimbiri komanso ngati chophatikizira pamano ndi mafupa. Monga chowonjezera cha chakudya, chimatsimikizira kukhazikika kwazinthu. Phosphoric acid imagwiritsidwanso ntchito ngati etchant mu electrochemical impedance spectroscopy (EDIC) komanso ngati electrolyte, flux ndi dispersant munjira zosiyanasiyana zama mafakitale. Kuwononga kwake kumapangitsa kuti ikhale yothandiza kwa oyeretsa mafakitale, pomwe paulimi phosphoric acid ndi gawo lofunikira la feteleza. Kuphatikiza apo, ndi gawo lofunikira pazoyeretsa m'nyumba ndipo amagwiritsidwa ntchito ngati mankhwala.

Mwachidule, phosphoric acid ndi chinthu chofunikira kwambiri chomwe chimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Chikhalidwe chake chokhazikika komanso chosasunthika, chophatikizidwa ndi acidity yake yocheperako, chimapanga chisankho choyamba pamapulogalamu ambiri. Kugwiritsidwa ntchito kosiyanasiyana kwa phosphoric acid, kuchokera ku mankhwala kupita ku zakudya zowonjezera, kuchokera kumayendedwe a mano mpaka kupanga feteleza, kumatsimikizira kufunika kwake pakupanga ndi moyo watsiku ndi tsiku. Kaya ndi caustic, electrolyte kapena kuyeretsa, asidiyu watsimikizira kuti ndi wothandiza komanso wodalirika. Ndi mitundu yosiyanasiyana ya ntchito komanso zopindulitsa, phosphoric acid ndi chinthu chamtengo wapatali m'mafakitale angapo.
