Products Description
Phosphorous asidhi iri muIsina Ruvara, inoonekera uye ine manyuchi mvura kana rhombic crystalline;Phosphorus asidhi haina hwema uye inonaka kwazvo kuvava;kunyungudika kwayo i42.35 ℃ uye kana yapiswa kusvika 300 ℃ phosphorous acid inova metaPhosphoric Acid;density yayo iri 1.834 g/cm3;phosphoric acid inonyungudika zviri nyore mumvura uye inogadziriswa mu ethanol;Phosphate acid inogona kutsamwisa ganda remunhu kukonzera phlogosis uye kuparadza nyaya yemuviri wemunhu;phosphorus asidhi inoratidza kuora kuri kupisa mumidziyo yeceramic;phosphate asidhi ine hydroscopicity.
Kushandiswa kwePhosporic Acid:
Technical giredhi Phosphoric Acid inogona kushandiswa kugadzira zvakasiyana-siyana zvePhosphates, electrolyte treatment liquids kana chemical treatment liquids, refractory mortar ine phosphoric acid uye inorganic coheretant.Phosporic acid inoshandiswawo secatalyst, drying agent uye cleaner.In coating industry phosphoric acid inoshandiswa se ngura-proof coating yesimbi;Seanogadzirisa acidity uye anovaka muviri wegiredhi yechikafu phosphoric acid inogona kuiswa kune zvinonaka, chikafu chemumagaba uye zvinwiwa zvakapfava pamwe nekushandiswa muwaini yekubikira sechinhu chinovaka muviri chinobva mbiriso kudzivirira kuberekana kwehutachiona husina basa.

Application
Phosphoric Acided pakubvisa huruva kubva panzvimbo dzesimbi Inoshandiswa sechinjo yengura nekuiunza kuti ibatane nesimbi ine ngura, kana maturusi esimbi uye dzimwe nzvimbo dzine ngura.Inobatsira pakuchenesa mamineral deposits, simenti nous smears uye tsvina yemvura yakaoma.Inoshandiswa kuita acidify chikafu uye zvinwiwa senge colas.Phosphoric Acid chinhu chakakosha pamishonga yekurwisa kusvotwa.Phosphoric Acid inosanganiswa ne zinc powder uye inoita zinc phosphate, uye inobatsira mune zvenguva simende yemazino.Mune orthodontics, zinc inoshandiswa senge etching mhinduro yekubatsira kuchenesa uye roughen pamusoro pemazino.Inoshandiswa sefetereza inoita muvhu rakatenderedza granule acidification inogadzirwa inovandudza mashandisirwo ephosphorus inoiswa uye inowanikwa murhizosphere.Nekuda kwehuwandu hwayo hwenitrogen (iripo seammonia), yakanakira zvirimwa zvinoda kudya uku muchikamu chekutanga.
