Propri\u00e9t\u00e9s de l'acide phosphinocarboxylique\u00a0:<\/h3>\n

APC<\/strong> est une solution parfaite pour le contr\u00f4le du tartre et de la corrosion dans les syst\u00e8mes de circulation d'eau froide et les syst\u00e8mes d'eau de remplissage des champs p\u00e9trolif\u00e8res. Ses propri\u00e9t\u00e9s, telles que l'introduction du groupe phosphonique dans le groupe carboxylique, en font une excellente option pour l'inhibition du tartre du sulfate de baryum, du sulfate de strontium et du tartre de silice. APC<\/strong> est \u00e9galement bien connu pour sa bonne propri\u00e9t\u00e9 de dispersion en termes de carbonate de calcium et de phosphate de calcium, ce qui le rend utilisable dans une large gamme de qualit\u00e9 d'eau. En plus de tous ces avantages, APC<\/strong> se distingue par sa stabilit\u00e9 chimique et sa forte tol\u00e9rance au chlore.<\/p>\n

Le dosage recommand\u00e9 est de 5 \u00e0 20 mg\/L, mais il peut \u00e9galement \u00eatre combin\u00e9 avec des organophosphines, un copolym\u00e8re, un sel de zinc ou du BTA pour de meilleures performances.<\/p>\n

Emballage et stockage\u00a0:<\/h3>\n

Il est fourni dans des f\u00fbts en plastique de 200L, des IBC (1000L) ou selon les exigences du client. Lorsqu'il est stock\u00e9 correctement dans un endroit frais et sec, la dur\u00e9e de conservation de ce produit est de 10 mois.<\/p>\n

Questions fr\u00e9quemment pos\u00e9es<\/h3>\n

\"Acide<\/p>\n

Qu'est-ce que l'acide phosphinocarboxylique ?<\/h4>\n

L'acide phosphinocarboxylique (PCA) est un compos\u00e9 organique utilis\u00e9 comme pr\u00e9curseur dans la synth\u00e8se des acides phosphiniques et des phosphonates. Il est \u00e9galement utilis\u00e9 comme inhibiteur de corrosion et comme agent ch\u00e9lateur.<\/p>\n

Quelles sont les propri\u00e9t\u00e9s de l'acide phosphino carboxylique ?<\/h4>\n

La formule chimique de l'acide phosphinocarboxylique est C2H5NO2P et son poids mol\u00e9culaire est de 149,09 g\/mol. C'est un solide blanc \u00e0 temp\u00e9rature ambiante et a un point de fusion de 58-59 \u00b0C.<\/p>\n

Comment est fabriqu\u00e9 l'acide phosphino carboxylique ?<\/h4>\n

L'acide phosphinocarboxylique peut \u00eatre synth\u00e9tis\u00e9 par la r\u00e9action du trichlorure de phosphore avec de l'hydroxyde de sodium, suivie de l'ajout d'anhydride ac\u00e9tique.<\/p>\n

Quelles sont les utilisations de l'Acide Phosphino Carboxylique ?<\/h4>\n

L'acide phosphinocarboxylique est utilis\u00e9 comme pr\u00e9curseur dans la synth\u00e8se des acides phosphiniques et des phosphonates. Il est \u00e9galement utilis\u00e9 comme inhibiteur de corrosion et comme agent ch\u00e9lateur.<\/p>\n

Quels sont les risques pour la sant\u00e9 de l'acide phosphino carboxylique?<\/h4>\n

L'exposition \u00e0 l'acide phosphinocarboxylique peut provoquer une irritation de la peau, des yeux et des voies respiratoires. L'ingestion du compos\u00e9 peut provoquer une irritation gastro-intestinale et des vomissements. Une exposition prolong\u00e9e peut causer des dommages au foie et aux reins.<\/p>","protected":false},"excerpt":{"rendered":"

Acide PhosphinoCarboxylique (PCA<\/strong>) est un compos\u00e9 chimique organique qui combine les caract\u00e9ristiques des phosphonates et des polyacrylates. Il est utilis\u00e9 comme \u00e9quilibre sp\u00e9cial de produits chimiques de traitement de l'eau, offrant une excellente stabilit\u00e9 thermique et chlor\u00e9e. APC<\/strong> a de bonnes propri\u00e9t\u00e9s de dispersion pour le tartre de carbonate de calcium et de phosphate de calcium dans les syst\u00e8mes d'eau froide en circulation, ainsi qu'une dispersion sup\u00e9rieure des boues d'eau de chaudi\u00e8re par rapport aux polyacrylates, polym\u00e9thacrylates et compos\u00e9s sulfon\u00e9s. De plus, il a une bonne inhibition du tartre pour le sulfate de baryum, le sulfate de strontium et le tartre de silice. Le PCA est un choix efficace pour une large gamme d'applications de traitement de l'eau.<\/p>\n
