상기 팽창 퍼라이트 구조물은 팽창 퍼라이트(PERLITE) 60 내지 95 퍼센트 중량부(wt%) 및 무기물 결합재 5 내지 40 퍼센트 중량부(wt%)를 포함하고, 상기 무기물 결합재의 중량 대비 5 내지 20 퍼센트 중량부(wt%)의 발색제가 더 포함된 것이다.The expanded perlite structure includes 60 to 95 percent by weight (PER%) and 5 to 40 percent by weight inorganic binder, and 5 to 20 percent by weight relative to the weight of the inorganic binder ( wt%) of the colorant is further included.
그러나, 상기 팽창 퍼라이트 구조물은 고온 건조기에서 고온으로 오랜 시간동안 건조해야 하고, 롤 컨베이어 이송수단에 의해 성형물이 이송되기 때문에 이송과정에서 성형물의 내부에 크랙이 발생할 수 있는 위험이 있었다.
However, the expanded perlite structure has to be dried for a long time at a high temperature in a high temperature dryer, there is a risk that cracks may occur inside the molding during the transfer process because the molding is transported by a roll conveyor conveying means.
따라서, 본 발명의 목적은 팽창 퍼라이트에 저온용 또는 고온용 바인더를 혼합하고, 성형된 성형물을 마이크로 웨이브 소성로에서 1차 소성함으로써, 성형물이 내부까지 충분히 소성되어 소성 시간을 단축할 수 있을 뿐만 아니라 높은 품질을 달성할 수 있는 팽창 퍼라이트 보드 제조방법을 제공하는 것이다.

성형된 성형물을 매끄럽게 표면처리하고, 성형물의 표면에 코팅액을 도포하는 단계(S103)와,Surface treatment of the molded molding smoothly, and applying a coating liquid to the surface of the molding (S103),
마이크로 웨이브 소성로에서 1차 소성한 후, 고온 소성로에서 2차 소성하여 제품을 완성하는 단계(S104)로 구성되는 것을 특징으로 한다.After the first firing in the microwave firing furnace, the second firing in a high temperature firing furnace is characterized in that it comprises a step (S104) to complete the product.
혼합 단계(S101)에서, 상기 저온용 바인더는 팽창 퍼라이트 2000 중량부일 때, 규산소다 400~600 중량부와, 안정제 50~200 중량부로 조성되는 것을 특징으로 한다.In the mixing step (S101), when the low-temperature binder is 2000 parts by weight of expanded perlite, 400 to 600 parts by weight of sodium silicate and 50 to 200 parts by weight of a stabilizer is characterized in that the composition.
다른 대안으로, 본 발명에 따른 팽창 퍼라이트 보드 제조방법은 팽창 퍼라이트 2000 중량부에 대해 물 1000~1500 중량부와 고온용 바인더인 유약을 450~800 중량부를 혼합할 수 있는 것을 특징으로 한다.In another alternative, the method of manufacturing an expanded perlite board according to the present invention is characterized in that it is possible to mix 450 to 800 parts by weight of 1000 to 1500 parts by weight of water and glaze which is a high temperature binder with respect to 2000 parts by weight of expanded perlite.
1차 및 2차 소성단계(S104)에서, 성형물은 컨베이어 이송방식으로 이송되는 것을 특징으로 한다.
In the first and second firing step (S104), the molded product is characterized in that the conveying method.
이것에 의해, 본 발명에 따른 팽창 퍼라이트 보드의 제조방법은 마이크로 웨이브 소성로에 의해 성형물이 내부까지 충분히 소성되며, 소성 시간을 단축할 수 있을 뿐만 아니라 높은 품질을 달성할 수 있고, 컨베이어 이송방식으로 성형물을 이송함으로써, 성형물의 내부에 크랙이 발생하는 것을 방지할 수 있는 효과가 있을 뿐만 아니라 절단 가공시 절단면에서 분진 등이 발생되지 않는 효과가 있다.
As a result, in the method of manufacturing the expanded perlite board according to the present invention, the molded article is sufficiently fired to the inside by the microwave firing furnace, which can shorten the firing time and achieve high quality, and the molded article by the conveyor conveying method. By transporting, not only there is an effect that can prevent the occurrence of cracks inside the molding, there is an effect that dust is not generated in the cutting surface during the cutting process.
도 1은 본 발명에 따른 팽창 퍼라이트 보드의 제조공정을 도시한 블록도1 is a block diagram showing a manufacturing process of the expanded perlite board according to the present invention
이하, 본 발명의 바람직한 실시예를 도면을 참조하여 상세하게 설명하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
도 1을 참조하면, 본 발명에 따른 팽창 퍼라이트 보드의 제조방법은 팽창 퍼라이트(expanded perlite) 2000 중량부에 대해 저온용 바인더 450~800 중량부를 물에 혼합한다(S101).Referring to FIG. 1, in the method of manufacturing an expanded perlite board according to the present invention, 450 to 800 parts by weight of a low temperature binder is mixed with water to 2000 parts by weight of expanded perlite (S101).
이때, 선택적으로 생광석 20~150 중량부를 혼합할 수 있다.At this time, 20 to 150 parts by weight of the ore may be optionally mixed.
그리고, 상기 저온용 바인더는 규산소다와 안정제(나노 실리카졸)로 구성되고, 팽창 퍼라이트가 2000 중량부일 때, 규산소다 400~600 중량부 그리고 안정제 50~200 중량부로 조성된다. 여기서, 팽창 퍼라이트가 2000 중량부일 때, 저온용 바인더의 450 중량부 이하로 혼합되면, 성형이 불가능하고, 팽창 퍼리아트가 2000 중량부일 때, 저온용 바인더가 800 중량부 이상이면, 소성후 균열이 발생하는 문제가 발생한다. The low temperature binder is composed of sodium silicate and a stabilizer (nano silica sol), and when the expanded perlite is 2000 parts by weight, the silica binder is 400 to 600 parts by weight and 50 to 200 parts by weight of the stabilizer. Here, if the expanded perlite is mixed at 450 parts by weight or less of the low-temperature binder, when the expanded perlite is mixed at 450 parts by weight or less, when the expanded ferrite is 2000 parts by weight, if the low-temperature binder is 800 parts by weight or more, cracks after firing There is a problem that occurs.
예를 들어, 팽창 퍼라이트 2000g에 대해 물 1000~1500g과 저온용 바인더 450~800g 그리고 생광석 20~150g을 혼합한다. 이때 저온용 바인더는 규산소다 400~600g과 안정제(나노 실리카졸) 50~200g을 혼합한 것이다.For example, for 2000 g of expanded perlite, mix 1000-1500 g of water, 450-800 g of low temperature binder, and 20-150 g of ore. At this time, the binder for low temperature is a mixture of 400-600 g of sodium silicate and 50-200 g of a stabilizer (nano silica sol).
다른 대안으로, 본 발명에 따른 팽창 퍼라이트 보드의 제조방법은 팽창 퍼라이트(expanded perlite) 2000 중량부에 대해 물 1000~1500 중량부과 고온용 바인더인 유약을 450~800 중량부를 혼합한다.Alternatively, the method of manufacturing an expanded perlite board according to the present invention mixes 1000 to 1500 parts by weight of water and 450 to 800 parts by weight of glaze, which is a high temperature binder, based on 2000 parts by weight of expanded perlite.
상기 팽창 퍼라이트는 이미 공지되어 있고, 생광석의 효능을 이미 잘 알려져 있어, 여기서 자세한 설명은 생략하기로 한다.The expanded perlite is already known, and the efficacy of the bio-ore is already well known, detailed description thereof will be omitted.
이후, 혼합물을 프레스 성형 방법으로 성형한다(S102).Thereafter, the mixture is molded by a press molding method (S102).
이후, 성형된 성형물을 매끄럽게 표면처리하고, 성형물의 표면에 코팅액을 도포한다(S103).Thereafter, the molded molding is surface-treated smoothly, and a coating solution is applied to the surface of the molding (S103).
이후, 마이크로 웨이브 소성로에서 1차 소성한 후, 고온 소성로에서 2차 소성하여 제품을 완성한다(S104).Thereafter, after the first firing in the microwave firing furnace, the second firing in a high temperature firing furnace to complete the product (S104).
이때, 마이크로 웨이브 소성로는 마이크로 웨이브가 성형물에 포함된 물을 직접 가열하기 때문에 단시간에 성형물의 내부까지 가열하게 됨으로써, 고온 소성로를 통과한 성형물이 내부까지 충분히 소성되어 고온 소성로에서의 소성 시간을 단축할 수 있을 뿐만 아니라 높은 품질을 달성할 수 있다. In this case, since the microwave firing furnace directly heats the water contained in the molding, the microwave firing furnace is heated to the inside of the molding in a short time, so that the molding having passed through the high temperature firing furnace is sufficiently baked to the inside to shorten the firing time in the high temperature firing furnace. Not only can it achieve high quality.
또한, 본 발명은 컨베이어 이송방식으로 성형물을 이송함으로써, 성형물이 마이크로 웨이브 소성로 및 고온 소성로를 통과하는 동안 진동에 의해 내부에 눈에 보이지 않는 크랙이 발생하는 것을 방지할 수 있으며, 또한 성형물의 절단 가공시 절단 가공면 내부(심층부)로부터 분진이 발생되는 현상도 방지되는 효가가 있다.
In addition, the present invention by conveying the molding by the conveyor conveying method, it is possible to prevent the invisible crack generated inside by the vibration while the molded product passes through the microwave kiln and high temperature kiln, and also the cutting processing of the molding There is an effect that also prevents the occurrence of dust from inside the deep cut surface (deep).
