Description

493974 V. Description of the invention (1) The present invention relates to an insect repellent device, which includes a cardboard strip, the cardboard strip including a toxic substance to insects. The invention also relates to a method of making such a device. More specifically (but not exclusively), the present invention relates to a mosquito coil, which comprises a cardboard roll impregnated with toxic substances to mosquitoes, and a method for making the mosquito coil. Conventional mosquito coils usually contain-a combustible material ', an adhesive, an organic filler, a perfume, and an insect repellent. This mosquito coil is made by mixing the above raw materials into a raw material paste 'to extrude or flatten it into a sheet & this sheet is punched into a roll and then dried to obtain a finished product. Wei; 5 /% Guotaizhu No. 54 4771 No. 3 discloses a mosquito coil, which is made of wood fiberboard and is widely used as an adhesive. Mixture of raw materials only = adult mosquito coil. The applied pressure tends to make the fibers in the plate non-straight, County C2; A, *, F are produced, and the plate is easily broken. Most mosquitoes made from such fragile plates are damaged during handling. 9 rolls during or after the consumer. Therefore, the first aspect of the present invention contains a burnable paper handle. You λ f J is a kind of insect repellent device. The term γ cardboard is used here to mean The liquid 飧, Λ j are better than anything. Fiber structure made of fibers. Felting in the heart. Since the paperboard is made of fiber, the fibers of the paperboard are not aligned during manufacturing. The shrinking fiber is made of flexible (and therefore less fragile). Therefore, the 20% cardboard is far more than the conventional cardboard, which involves the compression of the board fiber into a single f & board insect repellent device, or the mosquito coils that are damaged during the subsequent use are not easy to package and transport.

The present invention still burns the same as the present invention. The present invention can make the smoke of the limited color of the present invention. Preferably, paper, at least the fiber used in cattle to complete the insect repellent device, grass or bamboo, which also reduces the liquid used for combustion, the cardboard strip, and the insect repellent strip. For large areas it tends not to be used by itself. The flexible bottom roll is also poured from the mosquito coil. Insect repellent color, one of which can be included in the production of leather pulp. The resulting water is best used as a support for cardboard. The board is best to produce dust, that is, small particles falling on the roll. This will leave fine powder on the surface that the user touches. The mosquito coil raw dust loses significant quality, which leads to its performance degradation. The advantage of not generating dust. The installation is also significantly lighter than the conventional mosquito coils, which also reduces the cost of delivery. The installation can also be made in a variety of colors. The conventional mosquito coils are often only green or black. It is known that mosquito coils produce less fiber, which is cellulose fiber. It is better to use one of the waste or newspaper. This makes the cost lower. M fiber, preferably at least bagasse and rice. The finished cardboard strip is more smoky. Base liquid, especially water. Rolled. The board supports the combustible cardboard in terms of length and thickness. The paper handle contains such a backing sheet to make this cardboard strip. Can't sustain self-sustaining burning. So avoid the backing

5. Description of the invention (3) The slice burns faster than a cardboard strip. The slat can still contain organic dyes, and the organic dye is preferably 0.5% to 2% of the paper slat. The organic dye enhances the burning characteristics of the paper strip ▲ Adding organic dye makes the burning of the paper strip more resistant to external factors such as the b, b, and s plate extinction. It also makes the burning effect insensitive to differences in the inherent characteristics of the strip. The organic dye can uniformly distribute the volume across the cardboard strip. This further advances the burning characteristics of the paper strip. The cardboard strips can still contain charcoal powder, and the charcoal powder is preferably 1 to 10% of the weight of the strip. Woody powder promotes burning of cardboard strips. The cross-section of the anti-paper strip must be roughly rectangular, and the thickness of the paper strip is preferably to +, 0.2 mm, and at least 0.6 mm, and preferably not more than ι · 9 mm. 1 · 8 mm is better. The width of the cardboard strip is preferably at least 2 mm, at least 5 $ super better. Such cardboard strips tend to have a burn rate and are not easily self-aggregating. See the sentence The density of the burning paper strip is preferably at least 4,000 kg m -3, and preferably at least 5 008 m; it is preferably not more than 750 kg m and not more than 650 kg ^ ft. better. Such cardboard strips exhibit long burning times and are lightweight. Α / ι Another aspect of the present invention is to propose an insect repellent device, which includes the following steps: /, clothing & Cheng Yue adds a material containing fiber structure in a liquid to form a liquid county, ~ Link fiber

The fiber structure is felted from the liquid suspension to form a dimensional, structural network;

According to the method of the present invention, it is wrapped; the dimension structure is such that one of the step board and the liner is shaped to reduce the liquid fiber netting, the netting and the paperboard after the transportation period is completed. Drive or make the method into the most roll-like method yet. The square back sheet can be made of materials. In this way, the material of the device can be dried and added in the form of the next year. It will look like another example of the known insects. It contains the following steps and contains cardboard, and W poisonous substances. The point of view of the insect repellent device is that the flexible fragrant rolls can be bent during transportation or by the user, and a material for fabricating the fiber structure of the insect repellent device is proposed to form a liquid suspension structure. The liquid suspension is felted to form an interaction. The connected fiber is dried and added in a shape to the insect and insect device. The moonlight includes the glue method, which can also include the prevention of cardboard deformation, including waste paper, so that the weight of the finished drive. Contains non-wood board; and toxic substances. It is less likely to be damaged in the middle like a conventional mosquito coil. The step of cutting the paper board to form a strip, the most adhesive agent adheres the paper board to a flexible bottom plate, and the paper is restrained while the adhesive agent is dried. 〇 Taken at least kraft pulp or waste newspaper reinfestation device. The manufacturing cost is relatively low. At the same time, the fiber ’is preferably at least bagasse, straw

Page 7 493974 V. Description of the invention (5) The finished cardboard strip is more flexible. At the same time, non-wood pulp is also used. Compared with wood paper liquid suspension, at least charcoal powder or the organic dye is penetrated or impregnated to the burning characteristics of the paper roll. The steps of adding organic dyes to the cardboard are best referred to as non-limiting examples. In the formula: Plan view of the mosquito coil of the invention; showing one of other implementations of the mosquito coil according to the present invention or one of bamboo. This reduces the fumes from combustion. The pulp is more environmentally friendly. The method can still include one of the organic dyes. Best inside the board. After such enhancement is completed, the mosquito can still include adding the solution to the mosquito. The invention is illustrated by the attached drawings. The first diagram of the figure shows a plan view according to the second embodiment of the second diagram A to the second diagram of the second diagram B; the third diagram depicts the thickness and burning rate change of the rectangular cardboard strip according to the invention; The fourth figure depicts changes in the width and burning rate of a rectangular cardboard strip according to the present invention; the fifth figure depicts the changes in density and burning rate of a rectangular cardboard strip according to the present invention. ❿ 1 · Back sheet 2: Cardboard roll The mosquito coil of the present invention. The mosquito coil includes the backing sheet 1 as a flexible paper sheet. The backing sheet 1 is formed of a cardboard roll 2 to provide reinforcement to produce a mosquito coil of a ruler. Second, it is cut by the first figure as a basis for a backing sheet 1 and a cardboard roll 2. Play a dual role: First, it is stable, flat, and easy to access

493974 V. Description of the invention (6) The air supply from one side to the other side of the cardboard roll 2 improves the performance of the mosquito coil. This reduces the burning rate of cardboard roll 2 by 20% compared with the conventional one. The paper backing sheet 1 is treated with a flame retardant additive so that it cannot sustain self-sustaining combustion. When the paper roll 2 is ignited, there is a possibility that a part of the backing sheet 1 near the burning end of the paper roll 2 is burned. However, since the backing sheet 1 cannot sustain combustion, the burning of the backing sheet 1 does not spread to the area of the backing sheet far from the burning end of the cardboard roll 2. Therefore, the burning of the backing sheet 1 follows the cardboard roll 2 and does not burn through the backing sheet 1 far from the cardboard roll 2. The backing sheet was also burned at the same rate as the cardboard roll 2. The paper backing sheet 1 is made of a newsprint material and has the advantage of being easily colored. It also combines good robustness and lightweight characteristics. The light weight of the backing sheet 1 significantly reduces the cost of distributing mosquito coils. The unit weight per square meter of the paper backing sheet 1 is usually selected from 0.03 to 0.1 kg m, in this case 0.05 5 kg m_2. To make the paperboard roll of this embodiment, a material consisting mainly of waste paper was used together with unbleached kraft pulp and waste newspaper to beat. Use waste paper that mainly contains non-wood fibers such as bagasse, straw, or bamboo. This fiber gives the finished board excellent strength and density. Non-wood fibers are also cheaper. The typical composition of this material is: Material Dry weight Waste paper (high percentage of non-wood fiber) 75 Unbleached wood pulp 10 Waste newsprint paper 15 The beating operation is made in water in a hydraulic beater with a consistency of 2.5%.

Page 9 493974 V. Description of the invention (7) This type of hydraulic beater is well known in papermaking technology. After the material disintegrates to obtain a uniformly mixed fiber slurry, an inorganic filter (such as calcium carbonate) is added in a conventional manner and dispersed uniformly. After this, the pH value of the mixture, e.g., due to the addition of sodium aluminate, is immediately increased to p Η 7 to 8. The scrap is then subjected to a moderate refining process well known in papermaking technology, resulting in a good spread of fibers. After the refining process, a cationic retention auxiliary solution (for example, SurSola K12L from BASF) is added, which has the effect of attaching inorganic filters to the fibers.

If necessary, add an organic dye to the slurry, it is better to infiltrate the wet paperboard to improve the color and burning characteristics of the final paperboard. Cardboard with an organic dye concentration of 0.5 to 2% by weight of the paperboard is preferred, because it makes the paperboard burn more resistant to extinction caused by external factors such as a breeze. It also makes burning more dull to the intrinsic qualities of cardboard. If necessary, add charcoal powder to the slurry during board production. It will also enhance the burning characteristics of the finished board, especially the charcoal powder accounts for 1 to 10% of the weight of the board. The slurry is then diluted to a consistency of about 0.6% and pumped into the storage tank of the paper machine. The fibers are then felted from the solution to form a web. The web was finally dried on a paper roll 1¾ to form a paper board and spread out at the end of the process. Controlling the density of the paperboard made by the paper machine with the conventional papermaking technology shows that the rush rate is 0.55 g / cm3 and the thickness is 5 mm. Other thicknesses and densities are also possible, as described below. The paper sheet is then punched out of a cardboard sheet and coated with an insect repellent. This coating

Page 10 5 Description of the invention (8) ------ The procedure must be completed with the conventional Tu Youcheng spraying insect repellent technique on cardboard rolls. An example of this technique is the content of 3 4 * 1 ^ back and then let it air dry. After the completion, the ash rate of the paperboard roll is about meters (0.00034 g / cm), and the burning speed of the paperboard roll 2 is through the center and center (0.4 cm / min). The solid containing adhesive, or dextrin adhesive, adheres to the back sheet 1 'The stickiness shrinks and makes the cardboard 12, or 5% to 10% dry. The adhesive will dry the back sheet 1 under pressure to move two. In order to avoid this, the cardboard roll 2 and the backing sheet 1 are dry-welded between the two flat plates, and the bottom plate is slightly heated. Second, other types of adhesives are used in other embodiments. Mm;: == :. The total length of the paperboard is about 5: = small: feet / second (° _... ^ Example 2 The second picture A to the second picture B are a number of other mosquito coils according to the present invention = one, shown mosquito coil The paperboard roll 2 has a rectangular cross section. The thickness and density of the paperboard roll 2 greatly affect the burning rate. Ruler 3 (Figure η ^ 7 is not a constant paperboard roll with a width of 5 mm and a density of 570 kg of male board; μ life mg / cm3) (burning rate) _1 pairs of paper (μ ΐ ΐ Ξ watch. As the thickness of the cardboard roll gradually increases towards h 8 mm, the clock ^ —1 increases from 6 seconds / meter to 1 5 0 0 seconds / meter (1 minute can become sloppy ^ minutes / cm). When the thickness exceeds 丨 · 8mm, the flammability ", ^ 疋, and the flame obviously have a tendency to extinguish. The mosquito coil paper of the present invention 9/8; the preferred thickness is 丨. 5 mm, but the thickness of cardboard roll 2 is still in the range of 0.2 to 1α · 6 to 1 · 8 mm (better).

493974 V. Description of the invention (9) The fourth picture shows the constant paperboard roll thickness of 1.5 mm and density of 570 kgm_3 (0.57 g / cm3) (burning rate) -1 to cardboard roll width chart. As shown in the figure, the widening of the paperboard roll reduces the burning rate, and the optimum width reached is 5 to 6 mm. After that, the combustion performance becomes uncertain and the flames have a clear tendency to extinguish. Cardboard roll widths perform well in the range of 2 to 6 mm (5 to 6 mm is better). The fifth figure shows the (burning rate) -1 density chart of paperboard rolls. When the density increases, the number of holes per unit of the cardboard decreases, resulting in a reduction in the burning rate to the flame extinction point. As shown in the fifth figure, the increase in density slows the burning rate until the density is about 550 kgm (0.55 g / cm3). After that, the increase in the density of the board before it increased to 740 kgm (0.74 g / cm3) only had a negligible effect on the burning rate. Cardboard rolls according to the present invention typically have a density of 400 to 750 kgm_3 (0.4 to 0.75 g / cm3). Density within the range of 5 50 to 6 50 kg _3 (0.55 to 0.665 g / cm3) is better 0
