摘要:
A reinforcing fabric includes a plurality of non-metallic reinforcing cords. The non-metallic reinforcing cords are at least partially enclosed in elastomeric material and are radiopaque. A method to make the reinforcing fabric includes rendering a plurality of non-metallic cords radiopaque using one or more radiopaque compounds and enclosing the non-metallic cords in elastomeric material. The reinforcing fabric includes the elastomeric material enclosing the non-metallic reinforcing cords. A tyre for a vehicle wheel includes at least one rubberized reinforcing fabric. The at least one rubberized reinforced fabric includes elastomeric material including a plurality of non-metallic reinforcing cords. The plurality of non-metallic reinforcing cords are radiopaque.
摘要:
An aqueous sol of colloidal particles of tungstic oxide (WO.sub.3)-stannic oxide (SnO.sub.2) composite having a particle size of from 2 to 7 millimicrons is prepared by blending an aqueous solution of tungstic acid and an aqueous solution of a stannate in a weight ratio of from 0.5 to 100 as WO.sub.3 /SnO.sub.2. Where the WO.sub.3 --SnO.sub.2 composite sol in an amount of from 2 to 100 parts by weight as the total of WO.sub.3 and SnO.sub.2 is blended with a sol of a 3- to 5 valent metal oxide having a particle size of from 4 to 50 millimicrons in an amount of 100 parts by weight as the metal oxide, a modified metal oxide sol collidal particles having a size of 4.5 to 60 millimicrons as surface-coated with the tungstic oxide (WO.sub.3)-stannic oxide (SnO.sub.5) composite colloidal particles is prepared.
摘要:
A method of producing abrasive fibers is disclosed, which comprises providing a conjugate fiber comprising at least one abrasive layer containing abrasive particles and at least one coating layer substantially covering the abrasive layer, and removing at least a part of the coating layer from the conjugate fiber with a solvent or a decomposer to expose at least a part of the abrasive layer from the coating layer.
摘要:
A partially carbonized inert fibrous flexible textile material is obtained when a scoured textile material which is a blend of a fibrous acrylonitrile polymer and a fibrous regenerated cellulosic material is impregnated with an aqueous solution of salts which salts are either (a) an ammonium halide and a lower copper alkanoate or (b) an ammonium phosphate and an alkali metal bichromate, the impregnated material heated in a stream of an oxygen-containing gas at 150.degree.-250.degree. C. and then further heated in a stream of inert gas so as to produce a surface temperature on the fibres of 275.degree. to 325.degree. C. and thus rendered substantially uniformly inert.
