Definitions

  • the present invention relates to a polymer composite comprising cornstalk stalk powder and a method and apparatus for obtaining cornstalk stalk strips from corn plants, and more particularly, to easily, economically isolate cornstalk stalk strips from corn plants.
  • the present invention relates to a method and apparatus for drying, and a polymer composite using cornstalk stalk powder obtained by the above method.
  • Polymer composite is a mixture of plant bio-fibers, such as wood powder, with synthetic resin polymers such as polypropylene (PP), polyethylene (PE: polyethylene), and vinyl chloride (PVC: polyvinyl chloride). , It refers to a product formed by adding a coupling agent, a UV stabilizer, a UV absorber, a pigment, and the like.
  • OSB Oriented Stranded Board
  • Particle Board MDF It's a totally different product from Medium Density Fiberboard, commonly known as synthetic wood or WPC (Wood Plastic Composite).
  • OSB and particle board are not biomass in powder form, but square biofiber flakes with at least one side of 25mm or more, and MDF is manufactured by pressure-molding fibers extracted in a cotton-like shape from plants, respectively. Urea, soy bean protein and similar adhesives are used. Typically, OSBs, particle boards, MDFs, etc. are classified as “composites” but are completely separate from “Bio-fiber polymer composites". Polymer composites, which do not use adhesives, began to be used in the 1990s, and in the 2000s, a wide variety of materials such as outdoor decking, landscaping, building exteriors, stair handles, wooden house structural materials, interior decoration materials, automotive interior materials, container box interior materials, ship interior and exterior materials, etc. It is used in the field.
  • the process of making a polymer composite can be divided into two parts.
  • the first step is to combine the various elements, combining them while raising the temperature to just under 200 ° C. This is called compounding, and the intermediate material obtained through this process is called compound.
  • the compound is put into a molding machine such as an extruder or an injection molder and extracted into the shape of the product.
  • the polymer composite is characterized in that no adhesive is used, unlike conventional composites such as OSB, particle board, MDF, and the like.
  • Wood powder has conventionally been used as a representative biofiber for producing polymer composites. For this reason, polymer composites have been called "wood plastic composites" (WPC).
  • wood powder has the following problems as a raw material of the polymer composite. First, due to the fact that it is pulverized into a powder of too small size (100-300 ⁇ m), and secondly, due to the large loss of biofibers during the decomposition process of lignin, it is impossible to achieve the effect of strengthening the structure as a fiber. There is a limit.
  • the compound is pressed very hard for strength strengthening to make a finished product.
  • the specific gravity (1.2-1.5) of the finished polymer composite is much higher than that of the compound (0.49). Since wood powder does not function properly as a biofiber, the fact that many raw materials are added and pressed hard to make finished products leads to an increase in material costs, production facility investment costs, and energy costs.
  • the polymer composite product using the wood powder has a disadvantage that the product itself is too heavy, the hardness is high, the workability is poor.
  • biofibers contained in corn stalks have several advantages.
  • a comparison of corn stalks and wood powder is shown in the table below.
  • the wood powder is made of northern soft wood such as unsong.
  • corn bran has an excellent characteristic of high cellulose density and low lignin ratio, compared to wood powder.
  • corn fiber fibers are only half the thickness of 20 ⁇ m, so the bond is very high when mixed with the polymer.
  • the short length of corn cob fiber compared to wood can not be a relative disadvantage. This is because, in the case of wood, it can only be used by grinding into very fine particles having a size of 0.1 to 0.3 mm.
  • the reason for making the wood powder fine is that it is necessary to use chemicals to lower the lignin content and neutralize the weakly acidic properties.
  • Northern soft wood has a pH value of about 8, which must be neutralized to be used as a raw material for the compound. Since the surface area of the particles should be wider to improve the efficiency of chemical treatment and reduce the amount of wastewater discharged, wood powder biofibers are provided in very fine powders of 0.1 to 0.3 mm in size. As a result of fine milling and chemical treatment, the wood powder is damaged in strength as a biofiber, but rather remains meaning only as a filler.
  • Corn cobs on the other hand, can be directly used as raw materials without undergoing this chemical process. Because it can be used directly without chemical treatment, the process is not only omitted, and the particle size does not need to be broken into fine powders in order to increase process efficiency. Rather, the polymer composite finished product can maintain particle size to an unobtrusive level.
  • the cornstalk powder itself even before it is separated into the shell powder and the genus powder, can be seen that it has superior properties to wood powder when used as a raw material of the compound and the polymer composite, only from the constituents, but In fact, the reality is that corn cob powder is not used as a raw material in the industrial field.
  • the reason for this is the problem of homogeneity and the problems of volume and specific gravity.
  • the polymer composite is manufactured by molding a compound in which vegetable biofibers and petrochemical polymers are mixed and blended. When making a compound, the homogeneity of the biofibers and the volume difference between the biofibers and the polymer, i.e. the specific gravity of the biofibers, become an important problem.
  • biofiber raw material is not homogeneous or if the volume difference between the biofiber and polymer is too large, a good compound cannot be made. That is, corn cob powder is unsuitable as a raw material of a polymer composite in homogeneity and volume (specific gravity).
  • cornstalk consists of "cornstalk rind” (CSR) and “cornstalk pith” (CSP).
  • CSR cornstalk rind
  • CSP cornstalk pith
  • AEs anatomical elements
  • the two substances differ not only in the composition of cellulose (Cellulose and Hemi cellulose) and lignin (Lignin), but also by five times in volume specific gravity.
  • Corn bar stalk powder is more flexible and solid than wood powder and has a specific gravity of 0.25.
  • Corn cob powder on the other hand, has a hard and hollow character, like a broken cane, with a specific gravity of only 0.05.
  • Corn bark powder is a mixture of two particles of completely different physical properties, so the homogeneity is poor, it can not produce a high-quality compound. Therefore, when corn cob powder is used as a biofiber, instead of one homogeneous biofiber particle, two bio-mass materials having different physical properties, that is, corn cob husk particles and cob particles, are added. Will be. Corn cob is a very good biofiber, whereas cob is just a solid waste of lignin and polysaccharides.
  • the compound facility when corn cob powder is used as a raw material, the compound facility does not compound two materials, a biofiber and a polymer, but three materials including a corn fiber, a corn cob outer powder, a polymer, and a corn cob powder. Is subjected to the load that needs to be compounded.
  • cornstalk powder volume, specific gravity.
  • Corn cob meal powder increases the volume of corn cob powder to decrease its specific gravity.
  • the table below shows the specific gravity of corn cob and cob powder.
  • the specific gravity of the cornstalk powder in the swollen state is only about 0.1g / cm 3 .
  • corncob meal which degrades the properties of polymer composite products.
  • the blending ratio of biofibers and polymers is 70:30 or 80:20 by weight.
  • the specific gravity of wood powder used is about 0.2 and the specific gravity of petrochemical polymer is about 1 or so. Therefore, the volume difference between the wood powder biofiber and the polymer is about 12: 1 when the blending ratio is 70:30, and about 20: 1 when the ratio is 80:20.
  • the volume difference is 24: 1 at the 70:30 blending ratio and 40: 1 at the 80:20 blending ratio.
  • Biofibers and polymers do not mix well. For two materials that do not mix well, the larger the volume difference, the more difficult it is to mix and combine them. The larger the volume difference between the biofiber and the polymer, the greater the load the compounding equipment has to bear. That is, when kneading vegetable biofibers and petrochemical polymers having different physical properties from each other, if the volume difference between the two materials is large, compound production itself is impossible. If cornstalk powder is used instead of wood powder, the volume difference becomes so large that it is impossible to produce a good compound. Therefore, separating the cob meal from the corn cob powder not only solves the problem of homogeneity, volume and specific gravity, but also improves the components of the biofiber. The characteristics of cornstalk outer shell powder are shown in the table below.
  • cornstalk outer shell powder As shown in Table 3, in the case of cornstalk outer shell powder, the cellulose content reaches 68%, and the lignin content deteriorates physical properties of the product is only 10%. Therefore, it can be seen that cornstalk outer shell powder has physical properties that improve properties such as durability of the polymer composite.
  • cornstalk stalks can be used as a very good raw material for making polymer composite boards, medium density fiberboards (MDFs), oriented stranded boards (OSBs), particle boards, and pulp.

  • the question of whether such biomass can be used economically is not only what materials can be extracted from the biomass, but also the preprocessing process involving the collection, transportation, and storage of the biomass is economical. It is often determined by the question of what can be done.
  • corn cobs containing a large amount of high quality biofiber have been made at least in various laboratory applications for industrial applications, for example, pulp using corn cobs, medium density fiberboard (MDF), and synthetic wood (Bio).

  • the term "chip” refers to thin flakes within 2.5 cm square.
  • 10 kg propionic acid is only 0.01 m 3 . It is virtually impossible to mix these two bulky materials quickly and economically.
  • Third, evenly mixing propionic acid in corn stalks is not easy to store.
  • One ton is about 15m 3 in the chip state, and about 10m 3 in the powder state. This means more than twice as much storage space as a tree.
  • the chips are about one ton of about 6.8m 3 it is about of about 5m 3 in powder form. Therefore, pretreating, transporting, storing, and storing the whole corn barn greatly increases the cost unless the outer and outer parts of the corn bar are separated and only a high specific bar is obtained.

  • the cornstalk is separated into the outer shell and the outer shell, and a method mainly using wind passages has been studied and proposed.

  • the specific gravity of the superficial powder is 0.25 in the agitated state, whereas the specific gravity of the superficial powder is only 0.05.
  • the problem of how much it blows in the wind is ultimately determined by the interaction between the weight and the drag force.
  • the outer shell is five times heavier than the outer shell, so if the particle size is the same, the outer particle is five times heavier than the outer shell. Therefore, when the size is the same or similar, the outer particle moves in the wind path in a completely different way than the outer particle.
  • the method has the following disadvantages.
  • the size of the particles is each. Some smaller ones may not even be 1 mm 3 , while others may be 1 cm 3 . Due to the large variation in particle size, the movement in the wind channel is also unpredictable.
  • Aziz Ahmed a researcher at the Forest Products Laboratory of the US Department of Agriculture, one of the world's most prestigious research institutes on biofibers, says that it virtually gives up on the separation of corn stalks and cobs: It is making a point. "It is not necessary to separate the cores. Not only is the ratio of the cores relatively low, but also the cores contain significant amounts of good quality biofibers.
