It is also easy to produce charge accumulated, and stable chemical performance, light specific gravity, possess good dispersibility in ethylene glycol, be difficult to precipitate, can make
For excellent modifying agent, polyester material is modified.
Kieselguhr, due to the construction of its special porous, has fine and smooth, loose, light weight, porous, water absorption and permeability is strong
Property, adds adsorptivity and the hygroscopicity that a small amount of kieselguhr can significantly improve material in macromolecule polymer material.
Sodium polyacrylate is the macromolecular compound with hydrophilic group, therefore has high-hydroscopicity and water-retaining property, adds
Water suction and the water retention property of polyester can be improved in polyester, widened polyester material range of application.
Bentonite is the aqueous clay pit based on montmorillonite, and its interlayer cation species determines bentonitic type, layer
Between cation for Na+ when claim sodium bentonite, sodium bentonite has very strong hygroscopicity and a dilatancy, adsorbable 8～15 times
