Use Hauni
AF3 and Hauni
AF2 system plug device carries out various tests to these samples.Hauni
AF3 moves Hauni under 600m/min
AF2 moves under 400m/min.What caused by processing horizontal is much obvious under the higher speed of service in observed difference on the performance, therefore, has described at Hauni in the present embodiment
The experimental test of carrying out on the AF3.For the such processing aid of ethoxylated alkyl phosphate ester additive need should be maximum on the machine of operation at a relatively high speed.
Using passive static bruss and do not using Hauni with passive static bruss
All test on the AF system plug device.Static bruss contains the rectangle configuration of ground connection conduction hairbrush, and this ground connection conduction hairbrush is suspended near the fine band of cellulose acetate, to reach the purpose of dissipation of static charge.First static bruss is installed between predraft roller and the slow thread roller.These static brusses are installed in relative position away from roll gap, contact with roller or the fine band of cellulose acetate to avoid bristle.Second static bruss is installed between slow propellers and the fast propellers.
The statistical summary of listed experimental test is summarized in the table 2 in the table 1, more clearly to demonstrate the ethoxylated alkyl phosphate ester additive processing horizontal to these two kinds of influences that the static bruss configuration produces.Electrostatic charge is measured above the fine band of exit, plasticizer storehouse cellulose acetate center.The application of 250ppm ethoxylated alkyl phosphate ester additive makes electrostatic charge reduce 13.7 kilovolts, has represented significant variation.Addition is doubled, and promptly the addition of 500ppm has brought 5.8 kilovolts the reduction of appending, and shows that positive convergence influences diminishing point.No matter the ethoxylated alkyl phosphate ester additive processing horizontal how, the use of static bruss all makes static measure to have reduced by 27.1 kilovolts.
Relate to fracture of wire each locational gathering in system plug device in the long monofilament velveteen accumulation, its length range is about 0.25～30cm.The problem that is associated with long monofilament velveteen comprises: discharge filament cluster suddenly from accumulation point, cause excellent quality defect or machine to destroy; The machine destruction that roller is reeled and caused; With keep instrument to clean the increase of needed maintenance work.Here adopted a kind of subjective ranking method, promptly system plug device operator is observing the accumulation of monofilament on the machine surface of exit, plasticizer storehouse after one period set time.Give 1 value corresponding to the best branch that very small amount of long monofilament velveteen occurs, and can represent the velveteen amount that increases progressively up to 10 minutes high value.
The application of 250ppm (weight) ethoxylated alkyl phosphate ester additive makes long monofilament velveteen reduce by 1.1 units, has represented significant variation.The use of 500ppm (weight) ethoxylated alkyl phosphate ester additive makes long monofilament velveteen reduce by 1.6 units for control group.The use of static bruss for all ethoxylated alkyl phosphate ester additive processing horizontals, all makes grade reduce by 1.9 units.
Measure for second kind of long monofilament velveteen and relate to quantitative measure, it is by the electron image on arsis production plug device surface is resulting at interval in regularity at whole velveteen test period.For the speed of the long monofilament velveteen that quantizes on machine, to assemble, carried out image analysing computer.This quantitative measure provides measuring of more objective and sufficient long monofilament velveteen.The application of 250ppm ethoxylated alkyl phosphate ester additive makes the quantitative speed of long monofilament velveteen accumulation be reduced to 4132 from 5982.The use of 500ppm ethoxylated alkyl phosphate ester additive makes that this identical numerical value is reduced to 3621, i.e. 39% reduction.In the presence of ethoxylated alkyl phosphate ester additive, the average level of quantitative long monofilament velveteen is 3877.
When having used the ethoxylated alkyl phosphate ester additive of 0ppm, static bruss makes this value be reduced to 4526 from 5982.When using static bruss in the presence of ethoxylated alkyl phosphate ester additive, the average level of quantitative long monofilament velveteen is 3634.The minimizing of long monofilament velveteen is having or not in the presence of the static bruss in the presence of ethoxylated alkyl phosphate ester additive, all roughly the same (3877 pairs 3634).Although in fact static bruss is to the influence of static reading bigger (3877 pairs 4526), having used ethoxylated alkyl phosphate ester additive than using static bruss separately has by a larger margin improvement to long monofilament velveteen.This static for the roll gap district is that an important factor provides some evidences.It has also pointed out to exist to monofilament and fine other mechanism of being with condition to exert an influence of cellulose acetate, for example influence that causes owing to the fiber roller friction.
Suppose that the power that electrostatic charge causes acting on the monofilament makes it extend outside the fine band of cellulose acetate, and interact with each surperficial generation of system plug device.And the interaction between roller may be the very strong factor that causes monofilament to extend the fine band of cellulose acetate plane.Be with extended monofilament when colliding system plug device surface or plasticizer, can rupture easily from the cellulose acetate fibre, cause forming long monofilament velveteen.
Confirm through some qualitative observations: the condition of having improved the fine band of cellulose acetate owing to ethoxylated alkyl phosphate ester additive as the use of processing aid.A kind of effect is that the bandwidth of the fine band of cellulose acetate narrows down and becomes and stablizes.In the experiment of carrying out under the ethoxylated alkyl phosphate ester additive of 0ppm, the fine band of cellulose acetate bandwidth is tended to pass in time and is fluctuateed, and often hits the guide rod in the exit, plasticizer storehouse outside 12 inches.250 with during 500ppm, the fine band of cellulose acetate some inches that narrow down, and the bandwidth of the fine band of the cellulose acetate quite stable that becomes.The part of the improvement of above-mentioned velveteen intuitively is because the fine band of cellulose acetate no longer hits the cause of the guide rod that is used as long monofilament velveteen accumulation position usually.Advantage in another processing is that plasticizer is used uniformity and may be made moderate progress owing to the unanimity of the fine band of cellulose acetate condition between whole plasticizer spraying operational period.
On the fine band of the cellulose acetate that representative processing the improves condition second be crucial to change and relates to the fine band of cellulose acetate and system and fill in interaction between the device roller.Hauni
AF3 system plug device from start to finish has 4 groups of rollers: predraft roller, slow curled hair roller, fast curled hair roller and conveying roller.On the ethoxylated alkyl phosphate ester additive processing horizontal of 0ppm, can observe the cellulose acetate fibre take to multiple in this system plug device the defined principal plane in cellulose acetate fibre tape channel with interior and in addition.When the fine band of cellulose acetate exposed from the gap that two rotation rollers form, the fine band of cellulose acetate tended to keep in touch or convergence with one of two rollers.This can retract the fine band of the cellulose acetate beyond the above-mentioned principal plane.Finally by downstream rollers be applied to the cellulose acetate fibre with on power the fine band of the cellulose acetate that has exposed from roll gap is separated.The appearance of this phenomenon can be summarized with the saying of beating before and after the fine band of cellulose acetate.Beat (floppiness) be undesirable be with inhomogeneous reinforcing because it has brought along the cellulose acetate fibre, this will cause taking at the Dichlorodiphenyl Acetate cellulose fiber and produce difference on remove curling.By after the fast curled hair roller, must there be one to be called loose significant process, in this process, fiber must form once more by these rollers and stretch and temporary transient curling of removing.It is loose that aforementioned reciprocating motion may change the short-term that is obtained, thereby cause the changeability of plug.
One of the most serious influence to system plug device process that is brought by this interaction between fine band of cellulose acetate and roller comprises generation around roller, and this must cause machine to produce fault.Around roller the time, the interaction between fine band of cellulose acetate ester and roller can not be overcome by the downstream traction of the fine band of cellulose acetate.On the contrary, the cellulose acetate fibre is with to continue to be attached to and is taken place on this roller repeatedly to rotate.Interaction between the roller in fine band of cellulose acetate and the system plug device is complicated, relates to the power of number of different types.A kind of important power relates to the air pressure difference that is brought out by mobile roller.
Second kind of power relates to the generation that produces contact and separate the electrostatic charge that causes subsequently owing to roller and fiber.Along with the surface of oppositely charged begins to separate, formed and to have produced the electric field that hinders the active force that separates.Measure according to above-described electrostatic charge, this mechanism may be one of contributive factor of effect to ethoxylated alkyl phosphate ester additive.
The 3rd group of power relates to the frictional force between roller and the fine band of cellulose acetate.The prescription of fiber conbidioning agent, i.e. the content of chemical substance and kind, all the frictional force to handled fiber has appreciable impact.Ethoxylated alkyl phosphate ester additive might have influence on the friction condition of the fine band of cellulose acetate, thereby influences the condition of itself and roller.The cellulose acetate fibre can bring the variable advantage of longer usefulness curve and lower peak pressure drop during by system plug device with overall movement more smoothly.This peak is partly defined by operating point, and beyond operating point, when adjusting for the tow amount that further increases unit length in the plug, this system plug device always breaks down.The advantage of oxygen base alkyl phosphate ester additive might be with this operating point of expansion for the above.Data in the table 2 show that because ethoxylated alkyl phosphate ester additive is handled, the pressure drop coefficient of variation has improved 12%.
The present invention obtains describing in detail by its concrete preferred embodiment, but still should be understood that, do not depart from the scope of the present invention with spirit in, can produce various variations and change.
