摘要:
There is provided a composition suitable for use as a coating composition which contains a halogen-containing complex phosphate of aluminum, other than a phosphate ester, dissolved in an organic solvent. The complex contains at least one chemically-bound molecule of an alcohol having from one to 10 carbon atoms. The complex is prepared by interacting an aluminum compound, such as aluminum halides, with an alcohol containing one to 10 carbon atoms and with phosphoric acid.
摘要:
Complex phosphates of aluminum containing a halogen and chemically-bound molecule of a hydroxy compound, namely, water. A typical example is a complex phosphate having the empirical formulate AlPClH.sub.11 O.sub.9. They are most conveniently prepared by the reaction of an aluminum halide with water and orthophosphoric acid, under relatively cool conditions. The compounds are generally soluble in water and polar organic solvents. They decompose at low temperatures to give aluminum orthophosphate, thereby providing a method for producing aluminum phosphate in many forms, for example, fibers, coatings, binders and fine particles, from a solution in water or organic solvents.
摘要:
A method for the preparation of refractory fibers wherein a composition comprised of a polar solvent solution of a metal compound and an organic polymer is extruded into converging gas streams which contain vapor of said solvent therein so as to yield a relative humidity of at least 80%, and subsequently removing at least a portion of the solvent from the fiber formed.
摘要:
Solid water-soluble aluminum phosphate complexes and binder composition which dissolve in water to give solutions containing aluminum ions and orthophosphate ions in such proportions as to provide an Al:P ratio of substantially 1:1 together with the anions of a carboxylic acid or a mineral oxyacid.
摘要:
A coated composition is made by dispersing or dissolving in an aqueous dispersion of a fluorocarbon polymer a halogen-containing complex phosphate of aluminum.
摘要:
An organic, plastics film having a coating on at least one surface of said film of an aluminium phosphate, the aluminium phosphate being produced from halogen-containing complex aluminium phosphates.
摘要:
A method is provided for preparing a fibre from a solution of a halogen-containing complex phosphate of aluminium. The complex contains at least one chemically-bound molecule of a hydroxy compound R-OH, where R is a hydrogen atom or an organic group. The complex is dissolved in water or an organic solvent. The solution is fibrized and then dried to produce the fibre.
摘要:
A complex suitable for making shapes used as moulds and bricks, for preparing coatings and for use as cements, fillers and the like comprising a halogen-containing complex phosphate of aluminum wherein the gram atom ratio of aluminum to phosphorus is substantially 1:1 and containing at least one chemically-bound molecule of water and/or chemically-bound oxygen-containing organic molecules, as binder.
摘要:
A therapeutic composition for the treatment of virus-induced cutaneous infections comprises a first material for blocking viral DNA replication and a second finely divided material which absorbs exudated fluid from vesicles. Preferred compositions comprise a lithium compound (as the material for blocking viral DNA replication) and silica (as the material for absorbing exudated fluid from vesicles). An example of composition in accordance with the invention comprises a lithium compound dissolved or suspended in an aqueous silica salt.
