Description
[ technical field ] A method for producing a semiconductor device
The invention belongs to the technical field of cigarette auxiliary material production. More particularly, the invention relates to a member capable of rapidly releasing moisture in a filter rod, and to a method of making the member.
[ background of the invention ]
After the cigarette is unsealed, the moisture of the tobacco shreds is gradually lost. Especially in plateau and dry areas, the moisture of the cut tobacco can be reduced to 8-10% within 24h after the cut tobacco is unsealed. The moisture loss of the tobacco directly influences the smoking quality of the cigarette, and particularly the burr feeling and the spicy feeling are obviously increased in the sensory quality.
The main consumer is the mainstream smoke portion of a cigarette. The essence of the mainstream smoke is aerosol, and the essence of the mainstream smoke is an interactive process of aerosol deposition and elution when passing through the cigarette filter. The particulate matters in the aerosol are intercepted by the diffusion deposition effect of the filter stick tows; meanwhile, the aerosol also elutes the volatile substances in the filter stick. Mainstream smoke can elute 5 to 12% of the volatiles on the filter rod under standard smoking test conditions.
A section of the member of the invention which can stably store moisture is introduced into the filter rod. When the consumer squeezes the member, water or an aqueous solution in the member is squeezed out of the frangible indentation in the smallest cross-section of the member. Moisture is rapidly absorbed by the tows, and when mainstream smoke passes through the tows soaked by the moisture, the moisture in the tows is eluted into the mainstream smoke, so that the aim of directly improving the moisture of the mainstream smoke is fulfilled.

The invention relates to a structural schematic diagram of a component capable of quickly releasing water in a filter stick, which is shown in the attached figure 1, wherein A is an injection molding part A, and B is an injection molding part B.
The structure of the injection-molded part A is shown in figure 2, wherein figure 2A is a top view of the injection-molded part A; fig. 2B is a cross-sectional view of the injection molded part a.
As can be seen from FIG. 2, the injection-molded part A is a trapezoidal cylinder; as can be seen from fig. 2A, an easily breakable indentation in the shape of a cross, a hexagon or a rhombus is provided in the upper cross section of the injection-molded part a. The upper section of the injection molding part A is provided with an easily-broken indentation, the easily-broken indentation is an easily-broken opening manufactured on the end face of the injection molding part, and the easily-broken indentation can be broken when a consumer extrudes the component in the using process, so that water in the component is extruded out of the component, the effect of releasing water into a filter rod tow is achieved, and finally the water of main stream smoke is promoted.
In the present invention, the breakable indentations may take other shapes besides cross, hexagon or diamond shapes, but they do not adversely affect the processing or the structure of the invention, and these shapes are also within the scope of the present invention.
The structure of the injection molding part B is shown in figure 3, and as can be seen from figure 3, the injection molding part B is a flat cylinder; wherein FIG. 3A is a top view of the injection molded part B; fig. 3B is a cross-sectional view of the injection molded part B.
According to the invention, the injection molding part A and the injection molding part B are prepared from 3.0-6.0 parts by weight of one or more main materials selected from polycaprolactone, medical grade PVC, food grade PP or polylactic acid and 0.4-1.0 part by weight of one or more auxiliary materials selected from acetyl tri-n-butyl citrate or glyceryl triacetate.
In the present invention, since the member is mainly used to stably wrap and store moisture, and the main material is a main material constituting the member, a water-impermeable injection molding material containing no harmful substances is selected as the main material, and the main material is a food-grade or medical-grade polymer material and is not dissolved in water.
The auxiliary materials are basically used for improving the performance of the main materials in the hot melting granulation process so as to enable the member to have certain elasticity and rupture performance, wherein the elasticity is that a consumer cannot feel harsh when extruding the member, and the rupture performance is that the member can be broken in the process of deformation of the breakable indentation, so that moisture is released.
Polycaprolactone, medical grade PVC, food grade PP or polylactic acid used in the present invention are all products currently marketed, for example polycaprolactone sold under the name capa-6800 by Perstorp, Sweden, medical grade PVC sold under the name LB110 by LG chemical company. Of course, any other chemical substance which has the property of using the main material of the invention and does not have adverse effect on the quick release of the water-releasing component in the filter stick can be used in the invention, and the substances are also within the protection scope of the invention.
The acetyl tri-n-butyl citrate or glyceryl triacetate used in the present invention is a commercially available product, such as acetyl tri-n-butyl citrate sold under the trade name ATBC-DGT0198 by Toyobo chemical company, and glyceryl triacetate sold under the trade name glyceryl triacetate by Tako corporation. Of course, any other chemical substance which has the properties of the auxiliary materials used in the invention and does not adversely affect the quick release of the water-dispersible component in the filter stick can be used in the invention, and such substances are also within the scope of the invention.
In the invention, when the dosage of the auxiliary materials is within the range, if the dosage of the main materials is less than 3.0 parts by weight, the modification of the material fails, which is specifically shown in that the material is over-molded, the strength of the high polymer material is greatly reduced, a trace amount is slightly less, so that the component material becomes brittle, and a large amount is slightly less, even the injection molding cannot be carried out; if the main material is used in an amount of more than 6.0 parts by weight, the material modification will also fail, specifically, the material is too hard, and the plasticizing effect is not significant. The extrusion hand feeling of the injection molding piece is hard, even the easily broken indentation can not be broken in extrusion, and finally the whole component can not release moisture; therefore, the amount of the main material is 3.0 to 6.0 parts by weight.
Similarly, when the amount of the main material is within the range, if the amount of the auxiliary material is less than 0.4 part by weight, the material modification fails, specifically, the material is too hard, and the plasticizing effect is not significant. The extrusion hand feeling of the injection molding piece is hard, even the easily broken indentation can not be broken in extrusion, and finally the whole component can not release moisture; if the using amount of the auxiliary materials is more than 1.0 part by weight, the modification of the material fails, which is specifically shown in that the material is over-molded, the strength of the high polymer material is greatly reduced, the component material becomes brittle, and even the injection molding cannot be performed; therefore, the amount of the main material is preferably 0.4 to 1.0 part by weight.
In the present invention, the liquid contained in injection molded part a serves the basic function of releasing from the breakable indentations when the consumer squeezes the component, wetting the strands, and thereby increasing mainstream smoke moisture. The liquid is one or more liquids selected from pure water, an aqueous food grade salt solution or an aqueous inorganic base solution.
According to the invention, the food grade salt is one or more salts selected from sodium bicarbonate, sodium carbonate, sodium citrate or sodium tartrate; the inorganic base is one or more bases selected from sodium hydroxide, sodium bicarbonate, sodium carbonate or calcium hydroxide.
According to the invention, the concentration of the edible salt solution is 0.1-0.5 mol/L; the concentration of the inorganic alkali solution is 0.08-0.10 mol/L.
In the present invention, it is not preferable that the concentration of the edible grade salt solution and the inorganic alkaline solution exceeds the concentration range, because the salt solution is added to the member mainly for improving the smoking taste of the cigarette, and therefore, the low concentration salt solution is effective in improving the taste properly, but if the concentration of the salt solution is increased, the efficiency of moisture escape from the solution is reduced, and the effect of the member on increasing the moisture of the mainstream smoke is reduced, so that the proper concentration is a key technical index.
