Phosphoric Acid | 7664-38-2
IiNkcazo zeeMveliso
I-asidi ye-Phosphorous ikwi-Colourless, i-transparent kunye ne-syrupy crystalline okanye i-crystalline ye-rhombic; i-asidi ye-Phosphorus ayinavumba kwaye incasa imuncu kakhulu; indawo yayo yokunyibilika yi-42.35℃ kwaye xa ifudunyezwa kwi-300℃ i-asidi ye-phosphorous iya kuba yi-metaPhosphoric Acid; ukuxinana kwayo yi-1.834 g/cm3;iasidi yephosphoric inyibilika ngokulula emanzini kwaye isombulule kwi-ethanol; I-Phosphate acid inokucaphukisa ulusu lomntu ukuba ibangele i-phlogosis kwaye itshabalalise umba womzimba womntu; i-asidi ye-phosphorus ibonisa ukutshisa okutshisa kwiinqanawa ze-ceramic; i-phosphate acid ine-hydroscopicity.
Ukusetyenziswa kwe-Phosporic acid:
Ibakala lobuchwephesha iPhosphoric Acid ingasetyenziselwa ukuvelisa iintlobo ngeentlobo zePhosphates, ulwelo lonyango lwe-electrolyte okanye ulwelo lonyango lwekhemikhali, i-refractory mortar ene-phosphoric acid kunye ne-inorganic coheretant.I-asidi ye-Phosporic ikwasetyenziswa njenge-catalyst, i-ejenti yokomisa kunye nesicoci. Kwishishini lokugquma i-asidi ye-phosphoric isetyenziswa njenge-rust-proof coating for metal; Njengesixhobo sokulawula ubumuncu kunye ne-agent yesondlo kwi-yeast food grade phosphoric acid ingagalelwa kwincasa, ukutya okunkonkxiweyo kunye neziselo ezilula kunye nokusetyenziswa kwishishini lewayini njengomthombo wezondlo zegwele ukuthintela ukuzala kwebhaktiriya engenamsebenzi.

Isicelo
I-Phosphoric Acided ekususeni uthuli kumphezulu wentsimbi Isetyenziswa njengesiguquli serusi ngokuyidibanisa ngqo nentsimbi erulileyo, okanye izixhobo zentsimbi kunye neminye imiphezulu erulileyo. Kuyanceda ekucoceni iidipozithi zamaminerali, i-samente nous smear kunye namabala amanzi anzima. Isetyenziselwa ukwenza i-asidi yokutya kunye neziselo ezifana ne-colas. I-Phosphoric Acid sisithako esibalulekileyo kwi-counter counter amayeza ukulwa nesicaphucaphu. I-Phosphoric Acid ixutywa ne-zinc powder kwaye yenza i-zinc phosphate, kwaye iluncedo kwisamente yamazinyo yethutyana. Kwi-orthodontics, i-zinc isetyenziswa njengesisombululo sokucoca ukunceda ukucoca kunye nokurhaxa ubuso bamazinyo. Isetyenziswa njengesichumisi esisabelayo emhlabeni ojikeleze igranule acidification iveliswa ephucula ukusetyenziswa kwephosphorus egalelweyo kwaye ifumaneke kwirhizosphere. Ngenxa yesiqulatho sayo se nitrogen (ekhoyo njenge ammonia), ilungile kwizityalo ezifuna ezi zondlo kwisigaba sayo sokuqala.
