摘要:
The present invention relates to polyoxometalate-coated alumina trihydrate dispersants prepared by combining a polyaluminum chloride having certain characteristics with alumina trihydrate particles. Such dispersants are useful for forming cationic alumina trihydrate slurries, which can be mixed with titanium dioxide to produce stable cationic slurry blends useful in paper, paper-board, and paint (coatings) applications. The dispersants are also useful for preparing cationic titanium dioxide slurries.
摘要:
Dispersion additive system can be applied to fibers or particles, exhibiting improved dispersion, by including in the additive system a sulfonic-acid derived compound such as 2-acrylamido-2-methylpropanesulfonic acid or a salt thereof.
摘要:
The present invention is a paper product including a thermally bondable fiber which may be surfactant coated. The paper product according to the present invention has improved strength and absorbency characteristics. The paper product of the present invention may be embossed and heat cured to result in an attractive and absorbent product.
摘要:
Papermaking sludge can be modified to a modeling clay-like consistency by the addition of one or more dispersing agents, such as polyacrylamide. The modified papermaking sludge (1; 33) can be formed into a number of useful products, such as sheets (4; 40) or extruded products (43).

摘要:
Described is a process for treating water to inhibit scale formation, comprising adding to the water an effective amount of a maleate copolymer having a weight average molecular weight of 500 to 7,000, a residual total monomer content of less than 1%, on a maleate copolymer dry weight basis, and comprising at least 50 mole percent of maleate monomer, whereby at least 70 mole percent of the carboxylic acid charge on the maleate monomer is neutralized prior to polymerization, and 10 to 50 mole percent of acrylate monomer.
