北京快三开奖结果彩票控 www.8hib.cn Jaypol™ polymers are acrylic-based polymers that are grouped into two categories: dispersants and rheology modifiers.
The Jaypol polymers series of dispersants are designed to enhance primary and secondary detergency and inhibit scale deposition. They work by:
- protecting carboxylated surfactants, bleach systems, whitening agents, etc., from inactivation by polyvalent ions;
- protecting fabrics from redeposition and encrustation with hardness salts, and
- protecting machine surfaces from scale deposition.
The fundamental action of the Jaypol polymers series of dispersants selected for the Home Care category is to adsorb on surfaces involved in the washing/cleaning cycle. This may be the surface of crystals of insoluble salts, soil and lime soap particles, or fabrics being washed. These dispersants will also work on complex hardness and heavy metal ions, effectively removing them from solution and preventing interference with other actives.
Products targeted at inhibiting the effects of hardness salts act by slowing growth of microscopic seed crystals. Crystals therefore do not become visible until a much higher concentration is reached – called the “threshold effect.” The adsorbed layer of inhibitor keeps the crystals dispersed and reduces scale deposition on surfaces. Products targeted at anti-soil redeposition adsorb on the fabric surface to repel emulsified oils and dirts, etc., by electrostatic and steric forces.
The Jaypol polymers series of rheology modifiers are targeted for aqueous systems and form tangled networks of polymer chains that give structure to water, effectively inhibiting flow. Raising the viscosity with Jaypol polymers will help stabilize emulsions and dispersions, or improve product handling and application attributes.
The Jaypol polymers series of rheology modifiers are supplied either as alkali swellable emulsions or their hydrophobically modified versions. They are activated on neutralization, when the coiled polymer expands to form the network of tangled chains. Other products maintain the coiled polymer dispersed in oil. On dilution and stirring, these liquid dispersion polymers are released to form the tangled chain network. When the complexity of the polymer network formed, its interaction with other ingredients in the solution and how the chains untangle under shear determine the rheological character imparted to the system by the products.
