I-Acid yePhosphoric 85% yezoLimo Umfanekiso obonakalisiweyo

I-Phosphoric Acid 85% yezoLimo

I-Phosphoric acid, ekwabizwa ngokuba yi-orthophosphoric acid, yiasidi ye-inorganic esetyenziswa rhoqo kumashishini ahlukeneyo. Inomlinganiselo we-asidi eqinile, ifomula yayo yeekhemikhali yi-H3PO4, kwaye ubunzima bayo be-molecular yi-97.995. Ngokungafaniyo nezinye i-asidi eziguquguqukayo, i-asidi ye-phosphoric izinzile kwaye ayiphuli ngokulula, iyenza ibe yinto ethembekileyo yokukhetha izicelo ezahlukeneyo. Nangona i-asidi ye-phosphoric ingenamandla njenge-hydrochloric, i-sulfuric, okanye i-nitric acids, yomelele kune-acetic kunye ne-boric acids. Ngaphezu koko, le asidi ineempawu eziqhelekileyo ze-asidi kwaye isebenza njenge-asidi ye-tribasic ebuthathaka. Kuyafaneleka ukuba uqaphele ukuba i-asidi ye-phosphoric i-hygroscopic kwaye ithatha ngokulula ukufuma emoyeni. Ukongezelela, inamandla okuguqula i-pyrophosphoric acid xa ishushu, kwaye ukulahleka kwamanzi okulandelayo kunokuguqula kwi-metaphosphoric acid.

Ukusetyenziswa

Ukuguquguquka kwe-asidi ye-phosphoric kuyenza ibaluleke kakhulu kumashishini ahlukeneyo, ngakumbi amayeza, ukutya kunye nokuveliswa kwezichumisi. Kwintsimi yamachiza, isetyenziswa ngokubanzi njenge-agent anti-rust kunye nesithako kwiinkqubo zamazinyo kunye ne-orthopedic. Njengesongezo sokutya, iqinisekisa umgangatho wemveliso ozinzile. I-asidi ye-Phosphoric iphinda isetyenziswe njenge-etchant kwi-electrochemical impedance spectroscopy (EDIC) kunye ne-electrolyte, i-flux kunye ne-dispersant kwiinkqubo ezahlukeneyo zoshishino. Iimpawu zayo ezitshabalalisayo zenza ukuba ibe yimathiriyeli ekrwada esebenzayo kubacoci bamashishini, ngelixa kwezolimo i-phosphoric acid iyinxalenye ebalulekileyo yezichumisi. Ngaphezu koko, iyinto ebalulekileyo kwimveliso yokucoca indlu kwaye isetyenziswe njenge-agent agent.

Ukushwankathela, i-asidi ye-phosphoric yikhompawundi eyimfuneko yemisebenzi emininzi esetyenziswa kakhulu kumashishini ahlukeneyo. Ubume bayo obuzinzile kwaye obungaguqukiyo, budibene ne-acidity ephakathi, yenza kube yinto yokuqala yokukhetha izicelo ezininzi. Uluhlu olubanzi lwe-asidi ye-Phosphoric yokusetyenziswa, ukusuka kumachiza ukuya kwizongezo zokutya, ukusuka kwiinkqubo zamazinyo ukuya kwimveliso yesichumisi, ibonakalisa ukubaluleka kwayo kwimveliso kunye nobomi bemihla ngemihla. Ingaba i-caustic, i-electrolyte okanye isithako sokucoca, le asidi ibonakalise ukusebenza kwayo kunye nokuthembeka. Ngoluhlu lwayo olubanzi lwezicelo kunye neepropathi eziluncedo, i-asidi ye-phosphoric iyi-asethi exabisekileyo kuwo wonke amashishini amaninzi.
