Description

一种岩棉的生产方法 One kind of rock wool production methods

技术领域 FIELD

[0001] 本发明涉及一种岩棉的生产方法,属于无机非金属材料制造领域。 [0001] The present invention relates to a process for the production of rock wool, belonging manufacturing inorganic non-metallic materials. 背景技术 Background technique

[0002] 岩棉制品是以炉渣和矿石原料制造的无机纤维制品,具有优良的绝热、吸声和防火性能,广泛应用于石油、电力、冶金、建筑等领域。 [0002] The inorganic fiber is rock wool raw ore and slag products manufacturing, has excellent thermal insulation, sound absorption and fire resistance, are widely used in petroleum, electric power, metallurgical, construction and the like. 目前生产岩棉的方法如下:采用高炉炼铁排出的矿渣配以玄武石或白云石等辅料经破碎后混合混合焦炭倒入冲天炉进行熔融,熔融后由炉嘴喷出然后经过离心机形成细的流股,然后经集流风环产生的高压空气喷吹后, 便成为岩棉;而后利用沉降室的抽风机形成的负压将所述岩棉收集并降落到网式输送机上运走。 Current methods of producing rock wool as follows: The blast furnace slag is discharged together with the adjuvants and the like basalt or dolomite crushed and mixed by the mixing coke cupola melt poured, injected from the nozzle after melting furnace and then through a fine centrifuge the stream, and then after blowing high pressure air through the air ring collector produced, becomes rockwool; followed by a negative pressure blower chamber formed by settling the rock wool and collected on a net conveyor to drop away. 但是经上述方法制得的岩棉产品质量不是很好,尤其是抗压强度低。 However, prepared by the above method is not very good quality mineral wool product, especially a low compressive strength.

发明内容 SUMMARY

[0003] 本发明的目的是为解决上述技术问题,提供一种岩棉的生产方法,用该方法制得的岩棉产品具有抗压强度高的优点。 [0003] The object of the present invention is to solve the above problems, there is provided a method for the production of rock wool, made of rock wool obtained by this method has the advantage of a high compressive strength product.

[0004] 本发明的上述技术目的是通过以下技术方案得以实现的: 1、一种岩棉的生产方法,包括以下步骤: [0004] The technical object of the present invention is achieved by the following technical solutions: 1. A method for producing rock wool, comprising the steps of:

①、选取矿渣为主要原料,配以玄武岩或硅石,在熔炉中熔融; ①, select the slag as raw material, with basalt or silica, melted in a furnace;

②、将上述熔融原料在离心机的作用下牵伸成纤维,并将所述纤维利用高压空气吹送至集棉机;在所述纤维吹送至集棉机的过程中,利用所述纤维与渣球的速差,将渣球分离出去;同时将作为粘结剂的水溶性酚醛树脂溶液均勻施加到所述纤维表面; ②, the raw material melted under the effect of the above-described centrifuge drawn into fibers and the fibers are blown using high pressure air condensor machine; blown fibers during the fiber dust collection machine, using the fiber and slag speed difference of the ball, the ball will be separated slag; simultaneously applied to the fiber surface as a uniform water-soluble phenolic resin binder solution;

③、所述纤维在集棉机的作用下形成初棉层,此时将所述初棉层在摆锤机的的作用下运送到输送机上,在输送机的输送带上形成多层折叠结构的棉毡; ③, the cotton fiber layer is formed under the influence of early cotton set, in which case the role of the transport layer of cotton early in the lower pendulum machine onto a conveyor, folding the multilayer structure is formed on the conveyor belt cotton mat;

④、将上述棉毡在加压打褶机的作用下,通过不同的速度组合使纤维分布发生变化,制造出结构棉; ④, cotton blankets under the above-described pressure effect pleating machine, through different combinations of fiber distribution rate changes, producing the structure of cotton;

⑤、将所述结构棉送入固化炉加压定型;同时鼓如220〜300°C的热风,使作为粘结剂的水溶性酚醛树脂溶液固化。 ⑤, the structure of cotton into a curing oven pressure shaping; while blowing hot wind of 220~300 ° C, the water-soluble phenol resin as a binder was cured.

[0005] 本发明上述技术方案中,渣球是指矿渣和玄武岩或硅石在高温处理下发生熔融, 但是并不能达到百分百的熔融,未熔融部分则形成渣,而该渣在与熔融态共同从炉嘴喷出并经高压空气分离的过程中,自动抱成团,形成渣球。 Above technical solution [0005] In the present invention, the molten slag ball means and basalt or silica slag at a high temperature processing, but does not reach the melting hundred percent, unmelted portion is formed slag, and the slag in a molten state and common discharged from the furnace through the nozzle and a high pressure air separation process, the automatic holds together, form a slag ball. 而该渣球因比熔融态质量大,体积大, 因此会先掉落,而熔融态则被吹送至离心机,从而实现分离。 And that due to a large mass of shot than in the molten state, large volume, and therefore will first fall, and were blown into the molten centrifuge, thereby achieving the separation.

[0006] 现有技术在集棉机中就形成了岩棉,而本发明中,在集棉机中形成厚度更薄的初棉层时就通过摆锤机的往复运动将初棉层运送到运输机的输送带上,此时在摆锤机的往复运动与输送带的单向运动的共同作用下,就会在输送带上形成多层折叠结构的棉毡,把原来单层排布的棉毡转化成分层均勻的立体排布的棉毡。 [0006] In the prior art machine condensor rock wool is formed, but the present invention is formed to be transported to the beginning of a thinner layer of cotton reciprocates pendulum machine First collector layer of cotton in cotton a conveyor belt, then under the action of a reciprocating pendulum motion unidirectional machine and conveyor belt, cotton mat will form a multilayer structure is folded on the conveyor belt, the original monolayer arrangement cotton uniform mat perspective conversion component layer arranged cotton blankets. 然后将该棉毡在打褶机的纵向压缩下再配以不同的速度的组合使得棉毡的纤维分布发生变化,形成新的结构,即所述的结构棉,也因此,使得本发明方法制得的岩棉产品的抗压强度得到提高。 The cotton is then longitudinally compressed felt at pleating machine together with a combination of different speeds such that the fiber distribution changed cotton blankets, the formation of new structures, i.e. the structure of cotton, therefore, that the process of the invention compressive strength of rock wool products have to be improved. [0007] 上述技术方案中,还在将纤维吹送至集棉机的过程中在纤维表面均勻地施加水溶性酚醛树脂溶液;然后在最后一个步骤中,鼓如220〜300°C的热风,使作为粘结剂的水溶性酚醛树脂溶液固化。 Process [0007] The above technical solution, the fiber is also blown set of cotton fibers is applied uniformly on the surface of water-soluble phenolic resin solution; then, in the final step, such as hot drums 220~300 ° C, so curing the water-soluble phenolic resin binder solution. 这一技术方案的实施也能使得本发明方法制得的岩棉产品的抗压强度得到提高。 Embodiment of this aspect of the present invention the method also enables the compressive strength of rock wool products obtained is improved.

[0008] 综上所述,经检测,本发明方法制得的岩棉产品抗压强度比普通法制得的岩棉提高3〜5倍。 [0008] In summary, the detection method of the present invention was 3 to 5 times the compressive strength of rock wool products obtained rock wool than ordinary method.

[0009] 作为上述技术方案的优选,所述矿渣的粒度范围在60mm〜100mm,超粒度范围< 10% ;玄武岩的粒度范围在15〜20mm,超粒度范围< 10% ;硅石的粒度范围在15〜20mm, 超粒度范围< 10%。 [0009] As a preferred embodiment of the above-described technique, a particle size range of the slag in 60mm~100mm, over the range of particle size <10%; particle size range of basalt 15~20mm, over the range of particle size <10%; particle size of the silica in the range of 15 ~20mm, super size range <10%.

[0010] 作为上述技术方案的优选,所述水溶性酚醛树脂的固含量在38〜似%之间,游离酚< 2%,游离醛< 2%,在25°C时粘度彡12cps,在180°C时固化时间< anin。 [0010] As a preferred embodiment of the above-described techniques, the water-soluble phenol resin solids content between like 38~%, a free phenol <2% free formaldehyde <2%, a viscosity of 12cps at San 25 ° C, at 180 ° C the curing time <anin.

[0011] 综上所述,本发明具有以下有益效果: 本发明方法制得的岩棉具有抗压强度高的优点。 [0011] In summary, the present invention has the following advantages: the method of the present invention has the advantage obtained by high compressive strength rock wool.
