I-Pengfa Chemical - Izinyathelo zokuqapha lapho usebenzisa i-phosphoric acid

      I-Phosphoric acidiyi-asidi ye-inorganic evamile enefomula yamakhemikhali i-H3PO4.Akulula ukwenza volatilize, akulula ukubola, kulula deliquescence emoyeni.I-Phosphoric acid iyi-asidi eqinile emaphakathi enephuzu lokucwebezela elingu-21°C.Uma izinga lokushisa liphansi kunalokhu kushisa, amakristalu e-hemihydrate azokwenyuka.Ukushisa kuzolahlekelwa amanzi ukuze kutholakale i-pyrophosphoric acid, bese kuphinde kulahlekelwe amanzi ukuze kutholakale i-metaphosphoric acid.I-Phosphoric acid inendawo ye-asidi, i-acidity yayo ibuthakathaka kune-hydrochloric acid, i-sulfuric acid, i-nitric acid, kodwa inamandla kune-acetic acid, i-boric acid, njll.

sebenzisa:

Umuthi: I-Phosphoric acid ingasetshenziswa ukulungisa izidakamizwa ezine-phosphorus, njenge-sodium glycerophosphate.Ezolimo: I-Phosphoric acid iyinto ebalulekile yokukhiqiza umanyolo we-phosphate (i-superphosphate, i-potassium dihydrogen phosphate, njll.), kanye nokukhiqizwa kwezakhi zokudla (i-calcium dihydrogen phosphate);

Ukudla: I-Phosphoric acid ingenye yezithako zokudla.Isetshenziswa njenge-ejenti emuncu kanye nokudla kwemvubelo ekudleni.I-Coca-Cola iqukethe i-phosphoric acid.I-Phosphate iyisengezo esibalulekile sokudla futhi ingasetshenziswa njengesithuthukisi somsoco;

Imboni: I-Phosphoric acid iyi-chemical material eluhlaza, futhi imisebenzi yayo eyinhloko imi kanje;

1. Phatha ingaphezulu lensimbi ukwenza ifilimu ye-phosphate engancibiliki endaweni yensimbi ukuvikela insimbi ekugqwaleni;

2. Ihlanganiswe ne-nitric acid njenge-agent yokupholisha amakhemikhali ukuze kuthuthukiswe ukushelela kwendawo yensimbi;

3. Phosphate esters, izinto zokusetshenziswa zokukhiqiza izinto zokuhlanza nezibulala-zinambuzane;

4. Izinto ezisetshenziswayo zokukhiqiza ama-flame retardants ane-phosphorus;

Izinyathelo zokuqapha lapho usebenzisa i-phosphoric acid:

Ukuze uvikele isikhumba ku-phosphoric acid, sincoma ukugqoka izingubo zokuvikela amakhemikhali ezifana namabhuzu, izingubo zokuzivikela namagilavu, sincoma futhi ukuthi uthenge izikhumba ezenziwe ngerabha yemvelo, i-polyvinyl chloride, irabha ye-nitrile, irabha ye-butyl noma igiya lokuvikela le-neoprene.

Ukuvikela ubuso noma amehlo ezintweni ezicasulayo nezibolayo, sincoma ukuthi kusetshenziswe izibuko zokuphepha ukuze kuvikelwe amakhemikhali.

Ngokungeziwe ekukhipheni komoya okuvamile, sincoma ukusetshenziswa kwe-air exhaust yasendaweni ukuvimbela izingozi zokuphefumula lapho usebenzisa i-phosphoric acid, zonke izinyathelo zokuphepha ezidingekayo zemvelo kufanele zithathwe, futhi intuthu ingase idinge ukuphumela ngaphandle ngokuqondile.
