Description

편면 이중-골심 골판지 성형장치{Single-Side Formed Dual-Medium Corrugated Board Forming Apparatus}Single-side Formed Dual-Medium Corrugated Board Forming Apparatus}

본 발명은 골심지가 이면지에 이중으로 적층되는 골판지를 성형하는 장치에 관한 것으로, 특히 이면지의 일면에 두겹의 골심지를 일련의 롤러열(roller train)에 의하여 동시에 접착시키는 편면 이중-골심 골판지 성형장치에 관한 것이다.The present invention relates to an apparatus for forming a corrugated cardboard in which the corrugated paper is laminated on the back paper in a double, in particular, to a single-sided double-corrugated cardboard molding device for simultaneously adhering two layers of corrugated paper on one surface of the back paper by a series of roller trains. It is about.

골심지가 이중으로 적층되는 골판지 성형장치를 포함하는 발명은 본인의 등록특허공보 특0181565에 개시되어 있다. 이러한 선행기술은 다중-골심 골판지를 성형하기 위한 방법 및 장치에 관한 것이다. 이 다중-골심 골판지 성형장치 중에서 적어도 초기의 편면 이중-골심 골판지(이면지의 일면에 두 장의 골심지를 적층시킨 골판지)(15)를 성형하기 위한 장치는 도 2에서 보는 바와 같이 편면 이중-골심 골판지 적층수단(10)이 그 주요 구성요소를 이루고 있다. 이 수단(10)에는 이면지(라이너) 및 두 장의 골심지를 각각 공급하기 위한 골심지 공급드럼들(11, 11a, 12, 13)이 부가적으로 설치되어 있다.The invention including a corrugated cardboard molding apparatus in which the corrugated cardboard is stacked in duplicate is disclosed in Japanese Patent Application Laid-Open No. 0181565. This prior art relates to a method and apparatus for forming multi-corrugated cardboard. Among these multi-corrugated corrugating apparatuses, an apparatus for forming at least an initial single-sided double-corrugated corrugated cardboard (corrugated cardboard having two corrugated sheets stacked on one side of a backing paper) 15, as shown in FIG. The means 10 constitute its main component. This means 10 is additionally provided with corrugated medium supply drums 11, 11a, 12, 13 for supplying a back paper (liner) and two corrugated mediums, respectively.

상기한 편면 이중-골심 골판지 적층수단(10)은 도 3에서 보는 바와 같이 제1골심지(14)와 제2골심지(19)를 안내하여 서로 동일하거나 서로 다른 골 피치 및 골 높이를 갖도록 연속적으로 성형하기 위한 두 쌍의 제1골성형롤러(16a, 16b)와 제2골성형롤러(17a, 17b), 이면지(18)를 첫번째로 상기 제1골심지(14)를 향하여 가압함으로써 상기 이면지(18)를 상기 제1골심지(14)에 연속적으로 적층시켜 편면 단일-골심 골판지(15)를 형성하고 나서 두번째로 상기 이면지 및 상기 제1골심지(14)를 상기 제2골심지(19)를 향하여 가압함으로써 하나의 편면 이중-골심 골판지(15)를 형성하도록 하는 일련의 가압수단으로 이루어져 있다. 이 가압수단은 제1골성형롤러(16b)와 제2골성형롤러(17b)의 양측에 위치하는 2개의 벨트 드라이브 롤(20)과 가운데에 위치하는 2개의 가이드 롤(21), 그리고 상기 벨트 드라이브 롤(20)과 가이드 롤(21) 사이에서 무한궤도 운동을 하는 프레스 벨트(22)로 구성되어 있다.The single-sided dual-core corrugated cardboard stacking means 10 is continuously formed to guide the first corrugated medium 14 and the second corrugated medium 19 and have the same or different bone pitch and bone height as shown in FIG. The backing paper 18 by pressing two pairs of the first bone forming rollers 16a and 16b, the second bone forming rollers 17a and 17b, and the backing paper 18 first toward the first corrugated paper 14. By continuously stacking on the first corrugated medium 14 to form a single-sided corrugated cardboard 15, and then secondly pressing the backing paper and the first corrugated medium 14 toward the second corrugated medium 19. It consists of a series of pressing means to form a one-sided double-core corrugated cardboard (15). The pressing means includes two belt drive rolls 20 positioned at both sides of the first bone forming roller 16b and the second bone forming roller 17b, two guide rolls 21 positioned at the center, and the belt. It consists of the press belt 22 which carries out an endless track movement between the drive roll 20 and the guide roll 21. As shown in FIG.

이러한 편면 이중-골심 골판지 성형장치에는 제1골성형롤러(16a, 16b)에서 성형되어 나오는 제1골심지(14)에 접착제를 도포하는 접착제 도포수단(23)을 제1골성형롤러(16a) 측에 설치하여 예열수단(24)에 의해 가열되어 공급되는 이면지(18)와 접착되도록 하고 있으며, 제2골성형롤러(17b)의 일측에도 접착제 도포수단(25)을 설치하여 제2골성형롤러(17a, 17b)에서 성형되어 나오는 제2골심지(19)에 접착제를 도포시킴으로써 이면지(18)에 접착된 제1골심지(14)의 일면에 제2골심지(19)가 다시 접착되도록 하고 있다.In this single-sided dual-core corrugated cardboard forming apparatus, the adhesive applying means 23 for applying an adhesive to the first corrugated core 14 formed from the first osteogenic rollers 16a and 16b has a side of the first osteogenic roller 16a. It is attached to the backing paper 18, which is heated and supplied by the preheating means 24, the adhesive applying means 25 is also installed on one side of the second bone forming roller (17b) to the second bone forming roller ( By applying an adhesive to the second corrugated core 19 molded in 17a, 17b), the second corrugated core 19 is bonded to one surface of the first corrugated medium 14 adhered to the backing paper 18 again.

그러나 위와 같은 선행기술은 2쌍의 골성형롤러 외에도 프레스 벨트를 위시한 일련의 가압수단이 부가되어 있어서 골이 형성된 골심지가 골성형롤러를 벗어나는 구간이 생김에 따라 골심지의 골과 높이를 측정하기 위한 별도의 측정장치가 필요하며 이러한 측정장치에 의하여 측정한 결과 제1골심지와 제2골심지의 위치가 어긋나는 경우에는 제1골심지 또는 제2골심지의 어느 한쪽의 장력을 조절하기 위한 장치와 그 보정값을 검증하기 위한 측정수단들이 필요했다. 이렇게 여러 측정수단과 보정수단이 필요하게 됨에 따라 설치공간이 커지고 성형시간이 비교적 느려지는 문제가 생기게 되었다.However, in the prior art as described above, in addition to the two pairs of bone forming rollers, a series of pressing means including a press belt is added, and thus, a bone wick having a bone is separated from the bone forming roller, so that the bone wick and the height of the bone wick are separately measured. If a measurement device of the first and second core deviate from the result of the measurement by the measuring device, the device for adjusting the tension of either the first core or the second core wick and the correction value is verified. Measurement measures were needed to achieve this. As a result of the need for several measuring means and correction means, the installation space becomes large and the molding time becomes relatively slow.

뿐만 아니라 상기한 선행기술에 의하여 얻어지는 편면 이중-골심 골판지는 충격흡수 효과가 매우 좋은 반면 압축강도가 비교적 떨어지고 풀의 접착공정과 관련하여 비교적 그 생산속도가 느리다는 단점을 가지고 있었다. 압축강도가 떨어지는 이유는 이면지의 일면에 서로 겹치게 접착되는 제1, 제2골심지가 골을 이루는부분 외에는 접착되어 있지 않기 때문에 발생하는 것으로 충격의 흡수력이 높으면서 압축강도가 낮은 용도로 이용할 수밖에 없는 제약을 받고 있다.In addition, the single-sided double-corrugated corrugated cardboard obtained by the above-described prior art had a very good shock absorption effect, but had a relatively low compressive strength and a relatively slow production rate with respect to the glue bonding process. The reason why the compressive strength is lowered is that the first and second corrugations, which are bonded to one surface of the backing paper, are not bonded to each other except for the part forming the bone, and the compressive strength is high and the compressive strength is limited. I am getting it.

본 발명은 상기한 바와 같은 선행기술에 따른 문제점들을 해결하기 위해 안출된 것으로서, 본 발명의 주된 목적은 이면지의 일면에 두 겹의 골심지를 일련의 롤러열(roller train)에 의하여 동시에 접착시켜 성형시간을 단축하고 설치공간을 줄이는데 있으며, 다른 목적은 골심지와 골심지 간의 접착방법을 달리함으로써 편면 이중-골심 골판지의 압축강도를 향상시키는데 있다.The present invention has been made to solve the problems according to the prior art as described above, the main object of the present invention is to simultaneously bond two layers of corrugated paper on one side of the backing paper by a series of roller train (roller train) to form a molding time Another object is to improve the compressive strength of one-sided double-corrugated corrugated cardboard by varying the bonding method between the corrugated core and the corrugated core.

본 발명은 상기 목적을 달성하기 위하여, 이면지와 두 장의 골심지를 각각 공급하기 위한 공급드럼들과, 상기 공급들에서 공급되는 골심지들을 각각 성형하는 두 쌍의 골성형롤러, 그리고 각각 성형된 골심지의 봉우리에 접착제를 도포하는 접착제 도포수단을 갖춘 것에 있어서, 상기 두 쌍의 골성형롤러들은 골심지가 서로 역방향에서 공급되도록 설치하고 그 골심지가 성형되어 나오는 출구쪽의 골성형롤러들을 서로 맞물리게 설치하며, 서로 접착된 두 겹의 골심지가 공급되는 이면지와 접착되도록 한쪽의 골성형롤러 출구쪽에 프레스롤을 연접시켜 설치한 것이다.In order to achieve the above object, the present invention provides a feed drum for supplying each of the backing paper and the two corrugated papers, two pairs of the bone forming rollers respectively forming the corrugated papers supplied from the feeds, and the peaks of the formed corrugated papers, respectively. In the adhesive having a means for applying the adhesive to the adhesive, the two pairs of the roller forming rollers are installed so that the corrugated core is supplied in the opposite direction to each other, and the oscillating rollers on the outlet side from which the corrugated core is molded are interlocked with each other and adhered to each other. The press roll is connected to the outlet side of one bone forming roller so that two layers of corrugated paper are supplied to the backing paper supplied.

상기 골성형롤러 측에는 골이 성형된 골심지들의 피접착면에 액상 규산소다 접착제 또는 전분에 가성소다와 함께 적량의 소포제를 첨가한 접착제를 무상(霧相)으로 분사시킬 수 있는 풀분무기를 설치한다.On the side of the bone forming roller, a spraying machine capable of injecting a liquid sodium silicate adhesive or an adhesive containing an appropriate amount of antifoaming agent together with caustic soda on starch to the surface to be bonded of the bone cores is formed in a gratuitous manner.

그리고, 상기 공급드럼들의 출구쪽에는 공급되는 이면지와 골심지들을 가열시키는 프리히터가 각각 설치된다.The preheaters for heating the backing paper and the corrugated paper to be supplied are respectively installed at the outlet side of the supply drums.

본 발명은 위와 같은 구성에 따라 이면지와 2장의 골심지는 각각의 공급드럼에서 프리히터를 거쳐 골성형롤러로 공급되는데, 2쌍의 골성형롤러는 서로 맞물려 돌아가며 위아래에서 공급되는 골심지들을 서로 일정하게 성형함과 동시에 한데로 합쳐져 그 일측의 프레스롤을 지나면서 이면지가 접착된다. 즉 2쌍의 골성형롤과 프레스롤이 일체화되어 오차 없이 서로 맞물려 돌아가면서 하나의 편면 이중-골심 골판지를 연속적으로 생산하게 되는 것이다.According to the above configuration, the backing paper and the two corrugated wicks are fed to the bone forming rollers through the preheaters in the respective feed drums. At the same time, they are joined together and the backing paper is bonded while passing through the press roll on one side. That is, two pairs of bone forming rolls and press rolls are integrated to rotate together without error, thereby producing one single-sided double-corrugated cardboard continuously.

이하 본 발명의 실시예를 첨부된 도 1에 의하여 설명한다. 도 2에 도시하고 있는 이면지와 2장의 골심지(이하 제1골심지 및 제2골심지라고 함)를 공급하기 위한 공급드럼들(11, 11a, 12, 13)에 대하여는 그 도시 및 설명을 생략한다.Hereinafter, an embodiment of the present invention will be described with reference to FIG. 1. The illustration and description of the supply drums 11, 11a, 12, and 13 for supplying the back paper shown in FIG. 2 and the two corrugated papers (hereinafter referred to as the first corrugated paper and the second corrugated paper) are omitted.

이면지(51)와 제1골심지(52) 및 제2골심지(53)는 각각 프리히터(54a, 54b, 54c)를 지나면서 가열되도록 하고 있으며, 이렇게 프리히터들(54a, 54b, 54c)에 의하여 가열된 이면지(51)와 제1골심지(52) 및 제2골심지(53)는 2쌍의 골성형롤러(55a, 55b, 56a, 56b)에 3방향에서 공급되도록 하고 있다.The backing paper 51, the first corrugated core 52, and the second corrugated core 53 are heated to pass through the preheaters 54a, 54b, and 54c, respectively, and thus by the preheaters 54a, 54b, and 54c. The heated backing paper 51, the first rib core 52, and the second rib core 53 are supplied to the pair of bone forming rollers 55a, 55b, 56a, and 56b in three directions.

2쌍의 골성형롤러(55a, 55b, 56a, 56b)를 제1골성형롤러(55a, 55b)와 제2골성형롤러(56a, 56b)로 구분하여 설명한다. 제1골성형롤러(55a, 55b)는 2개가 상하로 맞물려 있다. 제1골성형롤러(55a, 55b)의 외면은 제2골심지(53)에 일정한 폭과 높이의 골을 성형하기 위한 파상의 골들이 형성되어 있어서 그 사이를 지나는 제2골심지(53)는 일정한 형태로 성형된다. 제2골성형롤러(56a, 56b)도 제1골성형롤러와 마찬가지로 2개가 상하로 맞물려 있다. 제2골성형롤러(56a, 56b)의 외면은 제1골심지(52)에 일정한 폭과 높이의 골을 성형하기 위한 파상의 골들이 형성되어 있어서 그 사이를 지나는 제1골심지(52)는 일정한 형태로 성형된다.The two pairs of bone forming rollers 55a, 55b, 56a and 56b will be described by dividing them into the first bone forming rollers 55a and 55b and the second bone forming rollers 56a and 56b. Two first bone forming rollers 55a and 55b are meshed up and down. The outer surface of the first bone forming roller (55a, 55b) is formed in the second corrugated corrugated bone for forming a bone of a certain width and height, so that the second corrugated wick 53 passing therebetween has a constant shape Is molded into. Like the first bone forming rollers, two second bone forming rollers 56a and 56b are engaged up and down. The outer surface of the second bone forming roller (56a, 56b) is formed in the first corrugated corrugated bone for forming a bone of a predetermined width and height, so that the first corrugated medium 52 passing therebetween has a constant shape. Is molded into.

제1골성형롤러의 윗쪽 롤러(55b)와 제2골성형롤러의 아래쪽 롤러(56b)는 좌우로 맞물려 있다. 그러니까 제1골성형롤러(55a, 55b)와 제2골성형롤러(56a, 56b)는 서로 동일하다. 제2골심지(53)는 제1골성형롤러(55a, 55b)의 아래에서 위로 공급되고, 제1골심지(52)는 제2골성형롤러(56a, 56b)의 위에서 아래로 공급된다. 제1골성형롤러의 아래쪽 롤러(55a)는 반시계방향으로 회전하며, 윗쪽 롤러(55b)는 시계방향으로 회전한다. 제2골성형롤러의 윗쪽 롤러(56a)는 시계방향으로 회전하며, 아래쪽 롤러(56b)는 반시계방향으로 회전한다.The upper roller 55b of the first bone forming roller and the lower roller 56b of the second bone forming roller are engaged left and right. Therefore, the first bone forming rollers 55a and 55b and the second bone forming rollers 56a and 56b are identical to each other. The second corrugated wick 53 is fed upward from below the first bone forming rollers 55a and 55b, and the first corrugated wick 52 is fed downward from the top of the second bone forming rollers 56a and 56b. The lower roller 55a of the first bone forming roller rotates in the counterclockwise direction, and the upper roller 55b rotates in the clockwise direction. The upper roller 56a of the second bone forming roller rotates clockwise, and the lower roller 56b rotates counterclockwise.

프레스롤(57)은 제2골성형롤러의 아래쪽 롤러(56b)와 연접되어 있다. 프레스롤(57)은 시계방향으로 회전하며 이면지(51)는 프레스롤(57)의 오른쪽 밑에서 공급된다. 접착제를 골이 성형된 제2골심지(53)의 봉우리에 선(線)모양으로 도포하는 일종의 접착제 도포수단인 풀롤(58a, 58b)은 2개가 구비되어 있다. 하나의 풀롤(58a)은 제1골성형롤러의 윗쪽 롤러(55b)와 연접되어 있으며, 또 하나의 풀롤(58b)은 제2골성형롤러의 아래쪽 롤러(56b)에 연접되어 있다.The press roll 57 is in contact with the lower roller 56b of the second bone forming roller. The press roll 57 is rotated in the clockwise direction and the backing paper 51 is supplied from the lower right of the press roll 57. Two pull rolls 58a and 58b which are a kind of adhesive application means which apply | coat an adhesive agent to the peak of the 2nd core wick 53 by which the bone was formed in a line shape are provided. One pull roll 58a is connected to the upper roller 55b of the first bone forming roller, and another pull roll 58b is connected to the lower roller 56b of the second bone forming roller.

무상의 접착제를 제2골심지(53)의 안쪽부분(제1골심지와의 대접면)에 분사하는 분무기(59)는 제1골성형롤러의 윗쪽 롤러(55b)에 위치하고 있다. 이 분무기(59)에 공급되는 접착제는 액상 규산소다와 전분접착제 혼합물을 선택적으로 사용하고 있다.The sprayer 59 which injects a free adhesive to the inner side of the second corrugated medium 53 (a contact surface with the first corrugated medium) is located on the upper roller 55b of the first bone forming roller. The adhesive supplied to this atomizer 59 uses a liquid sodium silicate and starch adhesive mixture selectively.

액상 규산소다는 인체에 영향을 줄 염려가 없는 용도에 적용되고, 전분접착제 혼합물은 인체에 영향을 미칠 수 있는 용도에 적용된다. 예컨대, 액상 규산소다는 산화나트륨 9~18%, 이산화규소 28~38%, 산화제이철 0.05% 이하, 물불용분 0.2% 이하의 범위내에서 그 성분이 결정된다.Liquid sodium silicate is applied for applications that do not affect the human body, and the starch adhesive mixture is applied for applications that may affect the human body. For example, the liquid sodium silicate component is determined within the range of 9 to 18% of sodium oxide, 28 to 38% of silicon dioxide, 0.05% or less of ferric oxide, and 0.2% or less of water insoluble content.

그리고 전분접착제 혼합물은 전분에 가성소다와 함께 적량의 소포제를 첨가한 것이다. 이때 전분에 대한 기타 첨가물의 배합 비율은 물 1420L를 기준으로 할때 전분 400KG, NaOH(용해수 33.3%) 29.6L, 붕산 5.96KG, 소포제 2.0L의 비율로 할 수 있다.The starch adhesive mixture is a starch adhesive with an appropriate amount of antifoaming agent along with caustic soda. In this case, the mixing ratio of other additives to starch may be based on the ratio of starch 400KG, NaOH (33.3% dissolved water) 29.6L, boric acid 5.96KG, and antifoam 2.0L based on 1420L of water.

위와 같은 실시예에 따른 작용상태를 보면, 이면지(51)와 제1골심지(52) 및 제2골심지(53)는 프리히터들(54a, 54b, 54c)을 통과하여 가열된 상태로 연속적으로 공급되고 있다. 제1골심지(52)는 제2골성형롤러(56a, 56b)에 위에서 아래로 공급되고, 제2골심지(53)는 제1골성형롤러(55a, 55b)의 아래에서 위로 공급되고 있다.Looking at the operation state according to the above embodiment, the backing paper 51, the first corrugated medium 52 and the second corrugated medium 53 are continuously supplied in a heated state through the preheaters 54a, 54b, 54c. It is becoming. The first rib core 52 is supplied from the top down to the second bone forming rollers 56a and 56b, and the second rib core 53 is supplied up from the bottom of the first bone forming rollers 55a and 55b.

이때 골이 성형된 제2골심지(53)의 내면(제1골심지와 접하는 면)에 해당하는 봉우리 부분에는 풀롤(58a)에 의하여 접착제가 선모양으로 도포된다. 그 다음 분무기(59)에 의하여 상기 접착제가 도포된 제2골심지(53)의 내면에 또 다시 액상의 접착제가 엷게 분사된다. 다음 순간, 제2골심지(53)는 골이 성형된 제1골심지(52)와 접착되는데, 이러한 접착은 롤러(55b)와 롤러(56b) 사이를 통과하면서 가압됨에 따라 이루어진다.At this time, the adhesive portion is applied in a line shape by the pull roll (58a) to the peak portion corresponding to the inner surface (surface contacting the first rib wick) of the second bone wick 53 is formed. Then, the liquid adhesive is lightly sprayed on the inner surface of the second core wick 53 to which the adhesive is applied by the sprayer 59. At the next moment, the second corrugated wick 53 is bonded to the first corrugated ridge 52 in which the bone is formed, and the adhesion is made while being pressed while passing between the roller 55b and the roller 56b.

골이 성형된 제1골심지(52)와 제2골심지(53)가 서로 접착된 뒤에는 풀롤(58b)에 의하여 제2골심지(53)의 외면 봉우리에 접착제가 선모양으로 도포되고 나서 롤러(56b)와 프레스롤(57) 사이에서 프레스롤(57)에 의해 가압되면서 이면지(51)와 접착된다. 이렇게 제2골성형롤러의 아래쪽 롤러(56b)와 프레스롤(57)을 통과하게 되면 완전한 편면 이중-골심 골판지(60)가 얻어진다.After the first corrugated bone 52 and the second corrugated 53 formed with bone are adhered to each other, an adhesive is applied to the outer peaks of the second corrugated medium 53 by a pull roll 58b, and then roller 56b. It is adhered to the backing paper 51 while being pressed by the press roll 57 between the and the press roll 57. Passing through the lower roller 56b and the press roll 57 of the second bone forming roller in this way, a complete single-sided double-core corrugated cardboard 60 is obtained.

분무기(59)에 의하여 무상의 접착제를 상기에 예시한 비율로 조성하여 제2골심지의 대접면에 분사하였더니 강도는 선행기술에 의하여 생산되는 일명 DW원단과 비교할 때 유사하거나 더 강한 강도를 낼 수 있었다. 또한 일정 두께를 갖는 도포가 아닌 무상(霧狀)의 분사에 의하여 미립자들끼리 매우 얇게 접착함으로써 그 작업시간과 건조시간이 짧아 최고 2배의 빠른 생산효과를 얻을 수 있었다.The spraying agent 59 formed a free adhesive at a ratio exemplified above, and sprayed it on the contact surface of the second corrugated core, and the strength was similar or stronger than that of the DW fabric produced by the prior art. there was. In addition, the fine particles are adhered to each other very thinly by spraying free of charge, rather than by coating with a certain thickness, so that the working time and drying time are short, resulting in up to two times faster production effect.

종래와 같은 프레스 벨트에 따른 일련의 가압수단이 필요치 않게 되며 이에 따라 각종 측정 및 보정수단이 필요없게 된다. 뿐만 아니라 시스템 자체가 서로 맞물려 있는 하나의 롤러열로 이루어져 있고 무상의 접착제를 2장의 골심지 대접면에 분사해 주기 때문에 성형시간을 단축시키고 설치공간도 줄여주게 된다. 또 위와 같이 무상의 접착제를 이용해 2장의 골심지를 미립자들의 결합형태로 접착함에 따라 일종의 가접착상태를 유지하게 된다. 이에 따라 강한 충격이 가해졌을 때에는 골심지와 골심지의 경사진 대접면에 휨모멘트가 걸려 서로 떨어져 나감으로써 충격을 흡수하고 다시 복원하는 특성을 갖게 됨으로써 궁극적으로 충격흡수효과를 가지면면서도 압축강도를 증대시키는 효과가 있게 되는 것이다.There is no need for a series of pressurization means according to the press belt as in the prior art, thus eliminating the need for various measurement and correction means. In addition, the system itself consists of a single row of rollers that are interlocked with each other and sprays free adhesive onto two corrugated plates to reduce molding time and reduce installation space. In addition, by bonding the two wicks in the form of a combination of fine particles using a free adhesive as described above to maintain a kind of temporary adhesion state. Accordingly, when a strong impact is applied, the bending moment is applied to the inclined contact surface of the core wick and the core wick so that they are separated from each other, thereby absorbing and restoring the impact, thereby ultimately increasing the compressive strength while having an impact absorption effect. Will be.
