Abstract

The process of producing short glass fiber with glass fiber fabric leftover pieces includes the steps of: soaking of the leftover pieces in strong alkali water solution, water washing to eliminate resin and strong alkali matter in the leftower pieces self draining off, cutting the leftover pieces into short sections, sucking the short sections into blower and exhausting it as short glass fiber. The short glass fiber may be used in producing asbestos tile and as reinforcing material in whitewashing wall and ceiling.

Description

Utilize the method for glass fabric leftover pieces processing short glass fiber
The invention belongs to a kind of method of handling the glass fabric leftover pieces.
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.
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 chopped strand.
The strong alkaline aqueous solution that soaks usefulness is NaOH or potassium hydroxide aqueous solution, and its concentration is 3~6%, 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 short glass fiber, 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.
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.
