DELAYED POLYACRYLAMIDE-CO-ALUMINUM HYDROXYL CHLORIDE GEL
The delayed gelling system of this invention is an organic-inorganic co-gel in which the immediate cross-linking that might otherwise result upon mixing a partially hydrolyzed polyacrylamide with aluminum is delayed, by using a gel-forming acid aluminum, a partially hydrolyzed or hydrolysable polyacrylamide soluble in acidic pre-gel conditions, and a delayed activator to elevate the pH to activate co-cross-linking of the polyacrylamide and aluminum into a co-gel.
The delayed gelling system of claim 1 wherein the partially neutralized aluminum salt comprises aluminum hydroxyl chloride. 16. The delayed gelling system of claim 1, further comprising a divalent or trivalent transition metal selected from titanium, iron, nickel, copper, zinc and manganese. 17.
Effect of Combined Sulfate-Chloride ttack on Concrete
Effect of Combined Sulfate-Chloride ttack on Concrete Durability- Reiew.. Ramezanianpour, E. Riahi Dehkordi * Ciil Engineering, mirkabir niersity of Technology, Tehran, Iran ABSTRACT: Chloride and sulfate ions damage the reinforced concrete in marine enironment due to the corrosion and formation of expansie products, respectiely.
The new gel developed is a low-concentration, low-viscosity delayed-crosslink polymeric gel system and is a significant improvement over traditional flowing gels used for fracture water shutoff in
Effect of 10% sodium ascorbate hydrogel and delayed
The artificial saliva which has an electrolyte composition similar to that of human saliva was formed from 1 g sodium carboxymethylcellulose, 5 mg calcium chloride, 0.1 g potassium chloride, 1 mg potassium thiocyanate, 40 mg potassium phosphate, and 100 g distilled deionized water.
A 1-week delayed bonding procedure after bleaching reduced compromised SBS of CR and RmGI. Applying 10% sodium ascorbate hydrogel in the treatment of bleached enamel surfaces reversed the compromised SBS and may be an alternative to delayed bonding, especially when restoration should be completed immediately after bleaching.
Effect of Sodium Ascorbate and Delayed Bonding on the Bond
Group A. The teeth were stored in artificial saliva at 37°C for a week. 24 Artificial saliva was prepared from 1.5 mmol/L of sodium bicarbonate, 4.8 mmol/L of sodium chloride, 137 mmol/L of potassium chloride, 4 mmol/L of potassium dihydrogen phosphate and 100 mL of deionized water. All the tooth surfaces were covered with celluloid tape except for a round area in the center of the labial
A novel weak gel of hydrolyzed polyacrylamide (HPAM) was prepared using inorganic–organic mixed crosslinker. The inorganic crosslinker was aluminum citrate (AlCit), and the organic crosslinker was 1,3,4,6-tetrahydroxymethylglycoluril (TMGU). The viscosity measurements showed that the viscosity of HPAM solutions was effectively increased from 80 mPas to 2500 mPas in stable state when 130 mg L
