Problems solved by technology

However, in the strong alkali medium of cement, ordinary glass fibers are easily corroded, the strength is reduced, the fibers become brittle, and the reinforcing effect is lost. The performance of the GRC products produced from this is very poor, so the alkali resistance of glass fibers needs to be solved.

Embodiment Construction

[0009] A kind of production method of alkali-resistant glass fiber, (1) the design of platinum alloy bushing: increase the content of rhodium in platinum-rhodium alloy to make it reach 10%, improve the mechanical strength of platinum-rhodium alloy at high temperature. 2. Add water-cooled joists on the lower surface of the drain plate. Through repeated tests and modifications, the technical problem of the bushing deformation at high temperature was effectively solved, and the service life of the bushing was extended, and a 400-hole joist cooling bushing was successfully designed.

[0010] The bushing plate is one of the main devices in glass fiber production, which is shaped like a trough container. During the wire drawing process, the molten glass flows into the bushing, which is adjusted to a suitable temperature, and then flows out through the nozzle on the bottom plate, and is stretched into continuous glass fibers by the high-speed rotating wire drawing machine below the o...

Abstract

The invention provides a production method of alkaline-resistance glass fiber, which is characterized in that (1) the design of a platinum alloy bushing plate meets the requirements that the rhodium content in the platinum rhodium alloy is increased so that the rhodium content can reach 10 percent, the mechanical strength of the platinum rhodium alloy at high temperature is improved, and a water introducing cooling support beam is additionally arranged on the inquiry lower surface of the bushing plate; and (2) impregnating agents consist of film forming ingredients, lubricating ingredients, antistatic ingredients and silane type coupling ingredients through being proportionally mixed. When the invention is adopted, the requirements of the wiredrawing operation can be met in the wiredrawing technology, the processing performance of the subsequent decoupling work procedure can be satisfied, the quality of glass fiber products and various technical properties of the cement can be improved, the technical problem of high-temperature deformation of the bushing plate is effectively solved, and the service life of the bushing plate is prolonged.

Description

technical field [0001] The invention relates to a reinforcing material for manufacturing glass fiber reinforced cement products, in particular to a production method of alkali-resistant glass fiber. Background technique [0002] Alkali-resistant glass fiber (AR fiber for short) is a special glass fiber that can resist the erosion of cement and other cementitious materials. It is a reinforcing material for the manufacture of glass fiber reinforced cement products (GRC for short). It is steel and An ideal substitute for asbestos, it is a type of composite material. Because GRC has many advantages such as light weight, high strength, waterproof, fireproof, strong design, good processability, and moderate price, it is widely used in many fields such as construction engineering, municipal engineering, agricultural engineering, water conservancy engineering, garden engineering, art sculpture, etc. Obvious technical effects have been obtained. However, in the strong alkali medium...
