Abstract

The invention discloses a glass fiber molding technique which comprises the following steps: 1. cutting a waste glass raw material into fragments with the diameter of greater than 3cm; 2. putting the glass fragments into a clean water tank, cleaning repeatedly, draining, and drying; 3. putting the cleaned glass fragments into a crucible; 4. igniting a blowtorch to preheat the glass; 5. igniting to heat the glass to 1100-1300 DEG C; 6. after the glass is molten, adjusting the temperature; 7. drawing glass yarns out of holes of the crucible; 8. after all the yarns are drawn out of the holes, pulling several times with hands, and preparing for yarn feeding; 9. winding the glass yarns on a roller, compacting with a pressure head, and starting the roller to perform rolling; and 10. taking down the rolled finished fibers, and packaging. The technique is simple and feasible, has the advantages of wide raw material sources and low cost, and is suitable for large-scale industrial production. The continuous temperature adjustment and continuous feeding are performed while yarn drawing, thereby ensuring continuous production; and thus, the technique has the characteristics of high production efficiency and stable product quality.

Description

Process for forming glass

Technical field

The present invention relates to process for forming glass.

Background technology

Glass fibre (abbreviation glass) adopts assorted discarded glass through a series of glass work in-process processed, its character and purposes are very extensive, its fineness is 0.03mm-0.06mm, product is thin as silk, soft as cotton, stretching resistance is strong, color is silvery white, nonpoisonous and tasteless, acid and alkali-resistance, corrosion-resistant, high temperature resistant, good insulation preformance, be widely used in building materials, oil, chemical industry insulating material, particularly as the main raw of glass reinforced plastic, demand increases day by day, needs more perfect, efficient production technique.

Summary of the invention

In order to overcome the deficiencies in the prior art, the invention provides process for forming glass, flow process is perfect, produces efficient.

The technical solution adopted for the present invention to solve the technical problems is:

Process for forming glass, comprises the following steps:

Step 1: discarded glass raw material cuts the fragment that footpath in blocks is greater than 3cm;

Step 2: glass fragment is put into clean water basin and repeatedly cleaned, draining is dry;

Step 3: the glass fragment after cleaning puts into crucible;

Step 4: blowtorch is ignited to preheating glass;

Step 5: light a fire glass heats to 1100 ~ 1300 degree;

Step 6: glass dissolves levelling temperature;

Step 7: from the eye pull-out glass yarn of crucible;

Step 8: after the silk of whole eye is pulled out, the company of catching takes out several, then prepares upper silk;

Step 9: glass yarn is wrapped on cylinder, and fasten with pressure head, start rolling;

Step 10: the finished fiber wound is taken off packaging.

As the improvement of technique scheme, if glass surface has greasy dirt in step 2, the caustic soda adding 4% with warm water is cleaned and can be used.

As the further improvement of technique scheme, with blowtorch, glass is burnt till as being energized after semiliquid in step 5, then add the combustion-supporting generation high temperature of gasoline, kerosene and alcohol.

Further, when glass metal in discovery crucible bubbles in step 5, first with spoon, bubble is needled, with hook, the glass metal in crucible is stirred back and forth again after deflating.

Further, before twining silk, first on cylinder, tenderizer is sprayed in step 9.

The invention has the beneficial effects as follows: present invention process simple possible, raw material sources are wide, and cost is low, are applicable to large-scale industrial production; By constantly regulating temperature while reeling off raw silk from cocoons, constantly feeding in raw material, ensure continuous seepage, production efficiency is high, good product consistency, steady quality.Present invention process flow process is perfect, and production efficiency is high, steady quality.

Embodiment

Process for forming glass, comprises the following steps:

Step 3: the glass fragment after cleaning puts into crucible;

Step 4: blowtorch is ignited to preheating glass;

Step 5: light a fire glass heats to 1100 ~ 1300 degree;

Step 6: glass dissolves levelling temperature;

Step 7: from the eye pull-out glass yarn of crucible;

Step 10: the finished fiber wound is taken off packaging.

In the present embodiment, preferably, if glass surface has greasy dirt in step 2, the caustic soda adding 4% with warm water is cleaned and can be used.Glass surface has the foreign material clean water such as silt; Greasy dirt need add the caustic soda cleaning of 4% with warm water, then through clean water once, guarantees to clean up.

In the present embodiment, preferably, with blowtorch, glass is burnt till as being energized after semiliquid in step 5, then add the combustion-supporting generation high temperature of gasoline, kerosene and alcohol.Use the oxidizers such as gasoline, kerosene and alcohol, the temperature of crucible is improved fast, accelerate glass and melt.

In the present embodiment, preferably, when glass metal in discovery crucible bubbles in step 5, first with spoon, bubble to be needled, with hook, the glass metal in crucible be stirred back and forth again after deflating.Occur that bubble must first be exitted, then the glass metal in stirring crucible, prevent bubble breaking from becoming small bubbles, affect follow-up step of reeling off raw silk from cocoons.

In the present embodiment, preferably, before twining silk, first on cylinder, tenderizer is sprayed in step 9.Tenderizer increases the flexibility of silk, is convenient to silk to twine on cylinder.

The above, just better embodiment of the present invention, but the present invention is not limited to above-described embodiment, as long as it reaches technique effect of the present invention with any same or similar means, all should fall within protection scope of the present invention.
