Kufotokozera Zamalonda
Phosphorous asidi ndi Colorless, mandala ndi manyuchi madzi kapena rhombic crystalline; asidi Phosphorus ndi fungo ndi kukoma wowawasa kwambiri;malo ake osungunuka ndi 42.35 ℃ ndipo ikatenthedwa mpaka 300 ℃ phosphorous acid idzakhala metaPhosphoric Acid;kachulukidwe wake wachibale ndi 1.834 g/cm3; asidi phosphoric amasungunuka mosavuta m'madzi ndipo amasungunuka mu Mowa;Phosphate acid imatha kukwiyitsa khungu la munthu kuti ipangitse phlogosis ndikuwononga nkhani ya thupi la munthu;phosphorous acid amawonetsa kutenthedwa kwa ziwiya zadothi;phosphate acid ali ndi hydroscopicity.
Kugwiritsa ntchito phosporic acid: +
Technical grade Phosphoric Acid angagwiritsidwe ntchito kupanga zosiyanasiyana Phosphates, electrolyte mankhwala zamadzimadzi kapena mankhwala mankhwala zamadzimadzi, refractory matope ndi asidi phosphoric ndi inorganic coheretant.Phosporic acid amagwiritsidwanso ntchito ngati chothandizira, kuyanika wothandizila ndi zotsukira.Mu ❖ kuyanika makampani phosphoric asidi ntchito ngati ❖ kuyanika dzimbiri zitsulo;Monga acidity regulator ndi zakudya wothandizila yisiti chakudya kalasi phosphoric asidi angagwiritsidwe ntchito oonetsera, chakudya zamzitini ndi zakumwa kuwala komanso ntchito vinyo moŵa monga zakudya gwero la yisiti kuteteza kuberekana mabakiteriya achabechabe.

Kugwiritsa ntchito
Phosphoric Acided pochotsa fumbi pazitsulo Amagwiritsidwa ntchito ngati chosinthira dzimbiri pochibweretsa kuti chigwirizane ndi chitsulo cha dzimbiri, kapena zida zachitsulo ndi malo ena omwe ali ndi dzimbiri.Zimathandiza kuyeretsa madontho a mchere, simenti nous smear ndi madontho amadzi olimba.Amagwiritsidwa ntchito popanga acidify zakudya ndi zakumwa monga colas.Phosphoric Acid ndi gawo lofunika kwambiri lamankhwala omwe amalimbana ndi nseru.Phosphoric Acid imasakanikirana ndi ufa wa zinki ndikupanga zinki phosphate, ndipo imakhala yothandiza pa simenti yanthawi yochepa yamano.Mu orthodontics, zinc imagwiritsidwa ntchito ngati njira yolumikizira kuti ithandizire kuyeretsa komanso kuvulaza mano.Amagwiritsidwa ntchito ngati feteleza m'nthaka mozungulira granule acidification amapangidwa kuti azitha kugwiritsa ntchito phosphorous yomwe imagwiritsidwa ntchito komanso kupezeka mu rhizosphere.Chifukwa cha kuchuluka kwake kwa nayitrogeni (yomwe ilipo monga ammonia), ndi yabwino kwa mbewu zomwe zimafunikira michere iyi poyambira.
