Copolym\u00e8re d'acide sulfonique d'acide acrylique-2-acrylamido-2-m\u00e9thylpropane<\/strong> est un inhibiteur de tartre et un dispersant id\u00e9al pour les conditions de pH \u00e9lev\u00e9 et d'eau alcaline. Il s'agit d'un copolym\u00e8re d'acide acrylique et d'acide 2-acrylamido-2-m\u00e9thylpropanesulfonique (AMPS) qui comporte des groupes carboxyliques, qui offrent une capacit\u00e9 d'inhibition et de dispersion \u00e0 grande \u00e9chelle en tant que forte polarit\u00e9 des groupes acide sulfonique. Cette combinaison de propri\u00e9t\u00e9s lui conf\u00e8re une tol\u00e9rance \u00e9lev\u00e9e au calcium et d'excellentes propri\u00e9t\u00e9s d'inhibition du tartre contre les tartres de phosphate de calcium, de carbonate de calcium et de zinc, ce qui en fait une option attrayante pour pr\u00e9venir les accumulations de min\u00e9raux \u00e0 des concentrations plus \u00e9lev\u00e9es. Lorsqu'il est combin\u00e9 avec des organophosphines, l'effet synergique est encore am\u00e9lior\u00e9.<\/p>\n

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

\"Acide<\/p>\n

Qu'est-ce que AA-AMPS ?<\/h4>\n

AA-AMPS est un tensioactif non ionique soluble dans l'eau. Il est utilis\u00e9 comme agent dispersant, \u00e9mulsifiant et agent mouillant dans de nombreuses industries et applications.<\/p>\n

Quelles sont les propri\u00e9t\u00e9s de AA-AMPS ?<\/h4>\n

AA-AMPS a un poids mol\u00e9culaire de 176 et une valeur HLB de 12,5. Il est soluble dans l'eau \u00e0 toutes les temp\u00e9ratures et a une bonne stabilit\u00e9 sur une large gamme de pH. Il est \u00e9galement compatible avec la plupart des tensioactifs anioniques, cationiques et non ioniques.<\/p>\n

Quelles sont les utilisations de AA-AMPS ?<\/h4>\n

L'AA-AMPS est utilis\u00e9 comme agent dispersant pour les pigments et les charges dans les peintures et les rev\u00eatements, comme \u00e9mulsifiant pour les \u00e9mulsions huile dans l'eau et comme agent mouillant pour la teinture et l'impression des textiles. Il est \u00e9galement utilis\u00e9 dans les fluides de travail des m\u00e9taux, les adh\u00e9sifs, les mastics et les \u00e9mulsions d'asphalte.<\/p>\n

Comment fonctionne AA-AMPS ?<\/h4>\n

AA-AMPS fonctionne en r\u00e9duisant la tension superficielle de l'eau, ce qui lui permet de mieux mouiller les surfaces et de disperser les pigments plus uniform\u00e9ment. Il aide \u00e9galement \u00e0 stabiliser les \u00e9mulsions en emp\u00eachant la coalescence des gouttelettes.<\/p>\n

Quels sont les avantages d'utiliser AA-AMPS\u00a0?<\/h4>\n

Les avantages de l'utilisation de l'AA-AMPS comprennent une meilleure dispersion des pigments et des charges, une stabilit\u00e9 accrue des \u00e9mulsions, un meilleur mouillage des surfaces et une tension superficielle r\u00e9duite.<\/p>\n

Quels sont les dangers des AA-AMPS\u00a0?<\/h4>\n

Les dangers des AA-AMPS comprennent l'irritation des yeux, de la peau et des voies respiratoires. S'il est ing\u00e9r\u00e9, il peut provoquer une irritation gastro-intestinale et une d\u00e9pression du syst\u00e8me nerveux central. S'il est inhal\u00e9, il peut provoquer une toux, une respiration sifflante et un essoufflement.<\/p>\n

Comment utiliser AA-AMPS\u00a0?<\/h4>\n

AA-AMPS doit \u00eatre utilis\u00e9 conform\u00e9ment aux instructions du fabricant ou selon les directives d'un professionnel qualifi\u00e9. Il doit \u00eatre stock\u00e9 dans un endroit frais et sec, loin des sources de chaleur ou des flammes nues.<\/p>\n

Quelles sont les pr\u00e9cautions d'utilisation de AA-AMPS ?<\/h4>\n

Portez un \u00e9quipement de protection individuelle appropri\u00e9 tel que des gants, des lunettes et un respirateur si n\u00e9cessaire lors de l'utilisation de l'AA-AMPS. Eviter le contact avec la peau et les yeux; en cas de contact, rincer \u00e0 l'eau pendant 15 minutes et consulter un m\u00e9decin si n\u00e9cessaire. En cas d'ingestion, ne pas faire vomir; appeler imm\u00e9diatement un m\u00e9decin ou un centre antipoison.<\/p>","protected":false},"excerpt":{"rendered":"

Acrylamido 2 Methylpropanesulfonic Acid (AA AMPS)<\/strong> is a reactive, hydrophilic, sulfonic acid acrylic monomer used to alter the chemical properties of a wide range of materials. It is commonly used in the production of polymers and copolymers products due to its unique ability to form strong bonds with other molecules. It is also known as 2-Methyl-2-[(1-oxo-2-propenyl)amino]-1-propane sulfonic acid. AA AMPS<\/strong> is an essential component for many industrial applications such as water treatment, papermaking, oilfield chemicals, and coatings.<\/p>\n","protected":false},"featured_media":1099,"template":"","meta":{"site-sidebar-layout":"default","site-content-layout":"default","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"default","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"product_brand":[],"product_cat":[28],"product_tag":[],"class_list":{"0":"post-1094","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-polycarboxylic-antiscalant-and-dispersant","7":"desktop-align-left","8":"tablet-align-left","9":"mobile-align-left","10":"ast-product-gallery-layout-horizontal-slider","11":"ast-product-gallery-with-no-image","12":"ast-product-tabs-layout-horizontal","14":"first","15":"instock","16":"shipping-taxable","17":"product-type-simple"},"yoast_head":"\nAcrylamido 2 Methylpropanesulfonic Acid(AA AMPS) -
