Applicable scope
Applicable to all kinds of ultrafine and nano inorganic packing (such as light and heavy calcium carbonate, magnesium hydroxide barite ore, alumina, etc.) or pigment (aluminum, titanium dioxide )the surface modification, and the activation of organic coatings, inks, products as dispersing agent directly use the settlement.
Usage and dosage
1. Dry modification:Through high-speed packing will powders mixed heating again kneading machine, directly add to or spray to join (better) measurement of coupling agent to handle the high-speed mixing, effect, In the process of powdery production or in grinding, grinding process to join this product, the method of using mechanochemical modification of powder on the surface modification.
2. Overall adulterating:In plastic, rubber products manufacturing process, can be mixed with polymers in packing add coupling agent, join in order to packing, coupling agent and a plasticizer, then add to join other components, forming processing after composite materials.
3. In the paint, ink, etc, as dispersant use directly.
4. Coupling agent for reference, the specific amount of 0.5 ~ 2%, depending on the packing and products quality and production process.
