Abstract
The invention discloses a high silica glass fiber rope and a fabricating technique thereof. Original soda borosilicate glass fiber protofilament is used as raw material, and the raw material is woven into glass fiber greige rope of certain thickness specification followed by technologies of acid leaching, water rinsing, heat treatment, post surface treatment and the like. The high silica glass fiber rope prepared by the above technologies has uniform and unanimous color, soft filament texture and smooth surface and can be easily and evenly backed-off. The invention has the advantages of high temperature resistance, heat insulation and thermal isolation, can be widely applied to heating element support and fire-resistant braided fabric material, or can be used for winding and forming various temperature durable products, etc.
Description
Technical field
The present invention relates to a kind of high temperature resistant rope and manufacturing technique thereof, be specifically related to a kind of resistant to elevated temperatures high silica glass fiber rope and manufacturing technique thereof, belong to extraordinary field of new.
Technical background
In the small household appliances industry, the colligation immobilization material that heating element heater is used is generally glass fiber material, requires to have heat resistance, and has certain support strength.The colligation material that present heating element heater is used is relatively poor for common alkali-free glass fibre rope heat resistance on low-end product, generally is applied to low power electrical equipment, and long-term serviceability temperature is below 500 ℃, and the life-span is shorter, is difficult to improve the class and the life-span of product.In high-power electric appliance, the temperature of heating element heater is higher, and general common alkali-free glass fibre rope is difficult to adapt to this environment all more than 800 ℃, needs to seek the higher material of heat resistance.High silica glass fiber rope then can solve this difficult problem well.
Summary of the invention
The present invention is achieved through the following technical solutions:
A kind of manufacturing technique of resistant to elevated temperatures high silica glass fiber rope comprises following processing step:
(1). original sodium borosilicate glass fiber precursor is moved back also, pools capital, and preparation becomes the glass fibre base rope of certain thickness specification.
(2). the base rope is wound on makes rope volume on the special ryce, evenly distribute and be placed in the acid leach groove with the hang volume of will restricting, then carrying out acid leach handles, selecting concentration is the hydrochloric acid of 1.5～3.5mol/L, heat to acid solution with steam, temperature is controlled between 85 ℃～98 ℃, handles 3～5 hours, circulates with acid-proof pump simultaneously and stirs and auxiliary bubbling stirs to strengthen ion exchange process.
(3). the surface spraying of the volume of restricting earlier after acid leach is handled is handled and is removed surperficial spent acid, is immersed in then in the clear water, injects hot water, and water temperature is controlled in 40 ℃～60 ℃ scopes, washes under water liquid flows.Use the surface of PH test paper test rope to contain acid condition simultaneously, when pH value washing greater than 5 time is finished.
(4). then carry out the elevated temperature heat typing and handle in continous mode HEAT SETTING stove, temperature is 600 ℃～750 ℃, and the processing time is 0.5 hour～1.5 hours.
(5). rope is dried film forming by behind the rotary integral impregnation after the heat treatment under 150 ℃～250 ℃, utilizes and divides silk winding apparatus coiling and molding promptly to obtain the finished product high silica glass fiber rope.
The invention has the beneficial effects as follows:
Through the high silica glass fiber rope of above prepared, color even unanimity, yarn matter softness, smooth surface, easily evenly unwinding.Have high temperature resistant, adiabatic, heat insulation advantage, be widely used in heating element heater support member, fire-resistant braided fabric material, also available Wrapping formed various heatproof goods etc.
