Abstract
The invention discloses a method for cleaning waste cellulose acetate, which comprises the steps of opening picking, web forming, sprinkling ethanol, cleaning in warm water bath and drying. The invention can realize the reuse of waste.
Description
Technical field:
The present invention relates to a kind of regeneration of acetate fiber.
Background technology:
In the cigarette filter tip production process, can produce the waste acetate fibre contain triacetyl glycerine in a large number, prior art generally with it as waste disposal, both wasted resource, again contaminated environment.
Summary of the invention:
The object of the present invention is to provide a kind of technology simple, can realize the waste acetate fibre ablution method of twice laid.
Technical solution of the present invention is:
A kind of waste acetate fibre ablution method is characterized in that: comprise the following steps: successively
1. will make in the cigarette filter tip process discarded acetate fiber through shredding, become net, be ethanol more than 80% at spray concentration on the acetate fiber then;
2. will put into warm tank through the acetate fiber of above-mentioned processing, clean oven dry then with syringe needle in the warm tank.
When 1. step becomes to net, with the acetate fiber that comes off in the net process, collect with airduct, spray concentration is the ethanol more than 80% then, puts into warm tank again, cleans with syringe needle in the warm tank, filters through filter press then, forms filter cake.
The ethanol consumption is 5～15% of acetate fiber amount by weight.Scavenging period is 5～30 minutes in warm tank.Bake out temperature is 100～120 ℃.
The present invention can fully realize twice laid, turn waste into wealth, and technology is simple and convenient, easy to operate, cleans up thoroughly, and is pollution-free.
The invention will be further described below in conjunction with embodiment.
The specific embodiment:
Embodiment:
A kind of waste acetate fibre ablution method comprises the following steps: successively
1. will make acetate fiber technology shredding routinely discarded in the cigarette filter tip process, become net, be the ethanol of (example 80%, 90%, 95%) more than 80% then at spray concentration on the acetate fiber, the ethanol consumption is 5～15% (examples 5%, 10%, 15%) of acetate fiber amount by weight, leaves standstill 5～60 minutes (example 5 minutes, 10 minutes, 20 minutes, 40 minutes, 60 minutes);
2. will put into the warm tank of ten thousand left and right sides syringe needles of commercially available tool through the acetate fiber of above-mentioned processing, clean 5～30 minutes (example 5 minutes, 15 minutes, 20 minutes, 30 minutes) with syringe needle in the warm tank, then in 100～120 ℃ (100 ℃, 110 ℃, 120 ℃ of examples) oven dry down, promptly get the acetate fiber product that cleans, can continue to utilize.
In addition, when 1. step becomes to net, with the acetate fiber that comes off in the net process, collect with airduct, spray concentration is the ethanol of (example 80%, 90%, 95%) more than 80% then, the ethanol consumption is 5～15% examples 5%, 10%, 15% of acetate fiber amount by weight), leave standstill 5～60 minutes (example 5 minutes, 10 minutes, 20 minutes, 40 minutes, 60 minutes); Put into the warm tank of ten thousand left and right sides syringe needles of commercially available tool again, clean 5～30 minutes (example 5 minutes, 15 minutes, 20 minutes, 30 minutes), filter through filter press then, form filter cake, regeneration with syringe needle in the warm tank.
Claims (5)
