Abstract
The present invention relates to a method for processing short cut glass fibers by utilizing the leftover pieces of glass fiber fabric. The method comprises the following steps: (1) the leftover pieces of the glass fiber fabric are soaked by water solution with strong alkalinity; (2) after the leftover pieces of the glass fiber fabric are washed and soaked by clear water, resin and strong alkaline substances on the leftover pieces of the glass fiber fabric are washed off; (3) the cleaned leftover pieces of the glass fiber fabric are taken out, and water on the leftover pieces of the cleaned glass fiber fabric is removed to be in a damp dry state; (4) the leftover pieces of the glass fiber fabric after water removal are cut into short sections by a cutter; (5) the leftover pieces of the glass fiber fabric after short cutting are absorbed in a blower so that after becoming short cut glass fibers, the leftover pieces of the glass fiber fabric are discharged from the blower. The processed short cut glass fibers can be used for making asbestos tiles and can also be used as reinforcing material for powdering wall surfaces and ceilings.
Description
Technical field
The invention belongs to a kind of method of handling the glass fabric leftover pieces.
Background technology
Glass fabric is after use, and its leftover pieces still do not have the method for recycling at present, can only discard in vain, not only cause the wasting of resources and contaminated environment.
Summary of the invention
The purpose of this invention is to provide a kind of method of utilizing glass fabric leftover pieces processing short glass fiber.
For achieving the above object, the present invention adopts following technical scheme: a kind of method of utilizing glass fabric leftover pieces processing short glass fiber, and it may further comprise the steps: soak the glass fabric leftover pieces (1) with strong alkaline aqueous solution; (2) with the glass fabric leftover pieces after the clear water cleaning and dipping, resin above the flush away and strong alkaline substance; (3) washed glass fiber cloth leftover pieces are pulled out draining to half-dried; (4) the glass fabric leftover pieces behind the draining are cut to cutting back with cutter; (5) the glass fabric leftover pieces after short the cutting are sucked blower fan, it is got rid of in blower fan beat and centrifugal action and discharging by blower fan after becoming the shape short glass fiber that looses.
The strong alkaline aqueous solution that soaks usefulness is NaOH or potassium hydroxide aqueous solution, and its concentration is 3～5%, and soak time is 3～5 hours.
10%～15% of water accounts gross weight behind the draining in the glass fabric leftover pieces.
Used blower fan is a centrifugal fan.
Glass fabric leftover pieces after short the cutting are of a size of 2～3 centimetres.
Adopt said method that the glass fabric leftover pieces are processed into the shape short glass fiber that looses, can be used to make asbestos shingle, can also when powder is built a wall face and ceiling, be added in the powder block material and be used as reinforcement material.Resource has not only been saved in application of the present invention, and can create new value, helps environmental protection simultaneously again.
The specific embodiment
Further specify the present invention below in conjunction with embodiment:
Embodiment 1: it is to soak in 3% the sodium hydrate aqueous solution that the glass fabric leftover pieces are dropped into concentration, can flood the glass fabric leftover pieces with sodium hydrate aqueous solution is as the criterion, time is 5 hours, with the resin dissolves above the leftover pieces, glass fabric leftover pieces after soaking are pulled out, drop in the clear water reserviors and clean repeatedly, resin above the flush away and NaOH, afterwards washed glass fiber cloth leftover pieces are pulled out draining to half-dried, account for 10% of gross weight with the content of water in the glass fabric leftover pieces and be advisable, above-mentioned half-dried glass fabric leftover pieces are cut to 2～3 centimetres cutting back with the cutter weak point.Glass fabric leftover pieces after short the cutting are sucked centrifugal fan, make it in blower fan, be subjected to getting rid of and beat and centrifugal action and discharging by blower fan after becoming the shape short glass fiber that looses.
Embodiment 2: it is to soak in 4% the sodium hydrate aqueous solution that the glass fabric leftover pieces are dropped into concentration, can flood the glass fabric leftover pieces with sodium hydrate aqueous solution is as the criterion, time is 4 hours, with the resin dissolves above the leftover pieces, glass fabric leftover pieces after soaking are pulled out, drop in the clear water reserviors and clean repeatedly, resin above the flush away and NaOH, afterwards washed glass fiber cloth leftover pieces are pulled out draining to half-dried, account for 12% of gross weight with the content of water in the glass fabric leftover pieces and be advisable, above-mentioned half-dried glass fabric leftover pieces are cut to 2～3 centimetres cutting back with the cutter weak point.Glass fabric leftover pieces after short the cutting are sucked centrifugal fan, make it in blower fan, be subjected to getting rid of and beat and centrifugal action and discharging by blower fan after becoming the shape short glass fiber that looses.
Embodiment 3: it is to soak in 5% the potassium hydroxide aqueous solution that the glass fabric leftover pieces are dropped into concentration, can flood the glass fabric leftover pieces with potassium hydroxide aqueous solution is as the criterion, time is 3 hours, with the resin dissolves above the leftover pieces, glass fabric leftover pieces after soaking are pulled out, drop in the clear water reserviors and clean repeatedly, resin above the flush away and potassium hydroxide, afterwards washed glass fiber cloth leftover pieces are pulled out draining to half-dried, account for 15% of gross weight with the content of water in the glass fabric leftover pieces and be advisable, above-mentioned half-dried glass fabric leftover pieces are cut to 2～3 centimetres cutting back with the cutter weak point.Glass fabric leftover pieces after short the cutting are sucked centrifugal fan, make it in blower fan, be subjected to getting rid of and beat and centrifugal action and discharging by blower fan after becoming the shape short glass fiber that looses.
