도 7에 도시된 바와 같이 예비가열기(300)의 제2고주파가열기(330)은 한 쌍의 상부플랜지(333)와 하부플랜지(334)가 서로 접촉하여 체결되는 상부관(331)과 하부관(332)으로 이루어져 있되, 상기 상부관(331)의 끝단부는 상부플랜지(333)보다 하부로 더 돌출되어 하부관(332)의 내경으로 삽입되어 있다.As shown in FIG. 7, the second high-frequency heater 330 of the preheater 300 includes an upper tube 331 and a lower portion where the pair of upper flanges 333 and lower flanges 334 are contacted with each other. Consists of a tube 332, the end of the upper tube 331 protrudes further downward than the upper flange 333 is inserted into the inner diameter of the lower tube (332).
즉, 상부관(331)의 외부 직경과 하부관(332)의 내부 직경이 서로 접촉하여 있는 것이다.That is, the outer diameter of the upper tube 331 and the inner diameter of the lower tube 332 is in contact with each other.
이때, 상기 하부관(332)의 끝단부에 형성된 하부플랜지(334)의 가장자리에는 상부로 돌출된 돌출편(335)이 형성되어 있으며, 상기 돌출편(335)의 상단에는 회동편(336)이 상하로 회동할 수 있도록 힌지결합되어 있다.At this time, the protruding piece 335 protruding upward is formed at the edge of the lower flange 334 formed at the end of the lower tube 332, and the rotating piece 336 is formed at the upper end of the protruding piece 335. It is hinged to rotate up and down.
또한, 상기 하부관(332)의 내주면에는 상기 상부관(331)의 끝단부가 접촉하도록 링형상의 걸림턱(337)이 돌출형성되어 있다.In addition, a ring-shaped latching jaw 337 is formed on the inner circumferential surface of the lower tube 332 so as to contact the end of the upper tube 331.
이에 제2고주파가열기(330)의 상부관(331)과 하부관(332)의 체결관계를 상세히 설명하면, 제2고주파가열기(330)의 상부관(331)을 하부관(332)의 내부에 삽입하여 상부플랜지(333)와 하부플랜지(334)가 서로 접하도록 한 후, 하부플랜지(334)의 돌출편(335)에 힌지결합되어 있는 회동편(336)을 회동시켜 상부플랜지(333)의 상면에 접촉되도록 한다.Therefore, the coupling relationship between the upper tube 331 and the lower tube 332 of the second high-frequency heater 330 will be described in detail, the upper tube 331 of the second high-frequency heater 330 of the lower tube 332 Inserted therein so that the upper flange 333 and the lower flange 334 in contact with each other, the upper flange 333 by rotating the rotating piece 336 hinged to the protruding piece 335 of the lower flange 334. Make contact with the top of).
상부플랜지(333)와 하부플랜지(334) 그리고 회동편(335)에는 각각 상하로 관통된 관통홀이 형성되어 있고, 체결시 상부플랜지(333)와 하부플랜지(334) 그리고 회동편(335)의 관통홀은 동일 수직선상에 위치하고 있다.The upper flange 333, the lower flange 334 and the rotating piece 335 is formed with a through hole penetrating up and down, respectively, when the upper flange 333 and the lower flange 334 and the rotating piece 335 The through hole is located on the same vertical line.
이때, 회동편(336)은 복수개가 부채꼴 형상으로 분할되어 있고, 분할된 각 회동편마다 돌출편(335)과 힌지결합되어 힌지축에 의해 회전시 원활한 상하회동이 가능하게 된다.At this time, the rotating piece 336 is divided into a plurality of fan-shaped, and each of the divided rotating piece is hinged to the protrusion piece 335, so that it can be rotated smoothly up and down by the hinge axis.
따라서, 상부관(331)은 하부관(332)에 삽입된 채, 원하는 방향으로 안정적으로 회전시킬 수 있으며, 적정한 방향으로 상부관(331)을 회전시켜 상부플랜지(333)와 하부플랜지(334)에 형성된 관통홀을 서로 일치시킨 후, 관통홀에 나사를 삽입시켜 너트로 체결하면 상부관(331)은 더욱더 안정적으로 하부관(332)에 체결되는 것이다.Therefore, the upper tube 331 can be stably rotated in the desired direction while being inserted into the lower tube 332, the upper flange 333 and the lower flange 334 by rotating the upper tube 331 in the proper direction After matching the through-holes formed in each other, the screw is inserted into the through-hole and fastened with a nut, the upper tube 331 is to be more securely fastened to the lower tube (332).

도 8은 본 발명 비중체가 포함된 합성수지 혼합물질 제조공정도이다.Figure 8 is a synthetic resin mixture manufacturing process chart containing the present invention non-body.
도 8에 도시된 바와 같이 합성수지에 첨가되어 무게감을 더해 주는 비중체가 포함된 합성수지 혼합물질는 제조방법으로서, 1단계 공정으로는 합성수지와 비중체를 혼합기(100)에 투입하게 된다.As shown in FIG. 8, the synthetic resin mixture including the non-polymer added to the synthetic resin to add weight is a manufacturing method. In the first step, the synthetic resin and the non-polymer are introduced into the mixer 100.
이때, 상기 합성수지는 재생폴리프로필렌(PP:Polypropylen)과 재생폴리에틸렌(PE:Polyethylene) 중 어느 하나를 택일하여 사용하게 된다.At this time, the synthetic resin is to use any one of recycled polypropylene (PP: Polypropylen) and recycled polyethylene (PE: Polyethylene).
상기 합성수지 혼합물질에는 착색제, 충진제, 가공조제, 산화방지제, 컴파운드가 더 포함되는 것으로, 중량%로 착색제 0.3～5%, 충진제 10～20%, 가공조제 0.2～1%, 산화방지제 0.2～0.5%, 컴파운드 0.3～5% 이고, 합성수지로 이루어지도록 한다.The synthetic resin mixture may further include a colorant, a filler, a processing aid, an antioxidant, and a compound, by weight% of a coloring agent of 0.3 to 5%, a filler of 10 to 20%, a processing aid of 0.2 to 1%, and an antioxidant of 0.2 to 0.5%. , Compound is 0.3 ~ 5% and made of synthetic resin.
그리고 상기 비중체는 합성수지 혼합물질 전체 중량의 10～75%가 차지하도록 한다.In addition, the non-body weight is 10 to 75% of the total weight of the synthetic resin mixture.
특히, 상기 비중체는 산화철 또는 산화알루미나 중 어느 하나를 사용하도록 한다.In particular, the non-body is to use either iron oxide or alumina oxide.
착색제, 충진제, 가공조제, 산화방지제, 컴파운드는 PP 또는 PE 재질용으로서 관용의 것을 사용한다.Colorants, fillers, processing aids, antioxidants, and compounds are conventional ones for PP or PE materials.
참고로, 착색제는 피착색물(플라스틱, 고무, 종이, 섬유, 가죽 등) 착색하는데 사용하는 물질이고, 충진제는 주로 비용을 절감하고 합성수지의 점도 조성, 경화수지의 균열 방지 등의 목적으로 접착제에 첨가하는 화학적으로 불활성 물질로서 접착력에는 기여하지 않는다.For reference, a colorant is a material used for coloring a colorant (plastic, rubber, paper, fiber, leather, etc.), and a filler is mainly used for the purpose of reducing costs, forming a viscosity of a synthetic resin, and preventing cracking of a cured resin. The chemically inert substance to be added does not contribute to adhesion.
착색제가 0.3중량% 미만으로 첨가되면 착색이 잘되지 않으며, 5중량%를 초과하여 첨가되면 착색의 효과가 크지 않으므로 경제적으로 효율이 떨어지게 된다.If the colorant is added in less than 0.3% by weight, the coloring is not good, and if it is added in excess of 5% by weight, the effect of the coloring is not so large economically inefficient.
착색을 위하여 안료 및 염료가 사용되며 안료로는 카본 블랙, 티탄 화이트, 크롬 열로 등이 쓰이고, 염료에는 오일 옐로, 오일 블루, 오일 레드 같은 유용성 염료가 사용된다.Pigments and dyes are used for coloring, and pigments include carbon black, titanium white, chromium furnace, and the like and oil-soluble dyes such as oil yellow, oil blue, and oil red.
일반적으로 마스터 배치 형태의 착색제가 가장 많이 이용된다.In general, colorants in the form of master batches are most commonly used.
가공조제는 합성수지의 가공성을 향상시키고 혼합성형 등의 공정을 원활히 행할 수 있도록 하는 것으로, 0.2중량% 미만으로 첨가되면 가공성이 떨어지고 1중량% 초과하여 첨가되면 첨가되는 양에 비해 효과가 떨어진다는 것이다.The processing aid is to improve the processability of the synthetic resin and to facilitate the process of mixing molding, etc., when the addition is less than 0.2% by weight, the workability is inferior, when added in excess of 1% by weight is less effective than the amount added.
일반적으로 가공조제로는 실리카와 실리콘의 혼합물이 사용된다.In general, as a processing aid, a mixture of silica and silicon is used.
충진제는 성형되는 제품의 물성을 좋게 하기 위하여 첨가되는 것으로, 10중량% 미만으로 첨가되면 효과가 미비하고, 20중량%를 초과하여 첨가되면 원래의 물성이 변화게 된다.Fillers are added to improve the physical properties of the product to be molded, if less than 10% by weight is not effective, when added in excess of 20% by weight will change the original properties.
충진제는 유리섬유, 탄산칼슘, 탈크, 미카, 규석, 목분, 쵸크 등이 있으며, 최근에는 수산화마그네슘(Mg(OH)2)이 사용되고 있다.Fillers include glass fiber, calcium carbonate, talc, mica, silica, wood powder, chalk, and the like, and magnesium hydroxide (Mg (OH) 2) has recently been used.
그리고 산화방지제는 높은 온도에서 산화 반응을 일으키는 여러 가지 물질에 대하여 산소의 작용을 막아주는 성질을 가진 물질이다.Antioxidant is a substance that prevents the action of oxygen on various substances causing oxidation reaction at high temperature.
산화방지제가 0.2중량% 미만으로 첨가되면 산화반응이 잘 일어나며, 0.5중량% 초과로 첨가되면 산화방지의 효과가 크지 않으므로 비용대비 효과가 떨어지게 된다.If the antioxidant is added in less than 0.2% by weight, the oxidation reaction occurs well, and when it is added in excess of 0.5% by weight, the effect of the antioxidant is not great, so the cost-effectiveness is lowered.
산화방지제가 0.2중량% 미만으로 첨가되면 산화반응이 잘 일어나며, 0.5중량% 초과로 첨가되면 산화방지의 효과가 크지 않으므로 비용대비 효과가 떨어지게 된다.If the antioxidant is added in less than 0.2% by weight, the oxidation reaction occurs well, and when it is added in excess of 0.5% by weight, the effect of the antioxidant is not great, so the cost-effectiveness is lowered.
산화방지제로는 주로 폐놀계, 유황계, 인계가 주로 사용되고, 주로 BHT로 대표되는 FDA 인가의 폐놀계 산화방지제가 사용되고 있다.As antioxidants, pulmonary phenol, sulfur and phosphorus are mainly used, and FDA-approved phenolic antioxidants represented by BHT are mainly used.
또한, 컴파운드는 합성수지와 철광석이 잘 섞일 수 있도록 도와주는 윤활유 역할을 하는 물질로서, 0.3중량% 미만으로 첨가되면 합성수지와 철광석이 잘 섞이지 않으며, 5중량%를 초과하여 첨가되면 너무 묽게 된다.In addition, the compound is a material that acts as a lubricant to help the synthetic resin and iron ore well mixed, if less than 0.3% by weight of the synthetic resin and iron ore is not mixed well, if more than 5% by weight is too thin.
일반적으로 컴파운드는 석회가루로 만든 것으로, 실리카(SiO2)첨가된 것을 사용하기도 한다.Generally, the compound is made of lime powder, and silica (SiO 2 ) is added.
이렇게 혼합기(100)에 투입된 합성수지와 비중체는 2단계 공정으로서 혼합기(100) 내에서 혼합되게 된다.In this way, the synthetic resin and the non-hydrogen added to the mixer 100 are mixed in the mixer 100 as a two-step process.
그리고 3단계 공정으로 상기 혼합기(100)에서 혼합된 합성수지와 비중체를 정량으로 배출하게 된다.Then, the synthetic resin and the non-body mixed in the mixer 100 are quantitatively discharged in a three step process.
또한, 4단계 공정으로 상기 혼합기(100)에서 배출된 합성수지를 용융하게 된다.In addition, the synthetic resin discharged from the mixer 100 is melted in a four-step process.
합성수지와 비중체를 용융하는 것은 고주파 가열기를 이용하여 300～400℃ 사이에서 행한다.Melting the synthetic resin and the non-body is carried out at 300 ~ 400 ℃ using a high frequency heater.
비중체는 금속재질이기 때문에 용융되지 않는다.Since the non-body is a metal material, it does not melt.
상기 4단계 공정에서 용융된 합성수지와 비중체는 5단계 공정으로서 금형이 장착되어 있는 사출기(200)에서 완제품 형상으로 성형되게 된다.The synthetic resin melted in the four-step process and the non-body is molded in the shape of the finished product in the injection molding machine 200 is equipped with a mold as a five-step process.
