如今的高品质耐火岩棉板主要由玄武岩和其他天然矿石制成。熔融后，将的四辊离心制棉工艺和高温玄武岩羊毛溶液放入4~7μM的不连续纤维中。然后在岩棉纤维上加入一定量的粘合剂、防尘油、少量自制、运输、硬化、切割等工序，根据用途制成不同密度的系列产品。接下来我们将介绍水平岩棉和垂直岩棉板之间的差异。
Today's high-quality refractory rock wool board is mainly made of basalt and other natural ores. After melting, put the advanced four roller centrifugal cotton making process and high-temperature basalt wool solution into 4 ~ 7 μ In discontinuous fibers of M. Then a certain amount of adhesive, dust-proof oil, a small amount of self-made, transportation, hardening, cutting and other processes are added to the rock wool fiber to make a series of products with different densities according to the purpose. Next, we will introduce the difference between horizontal rock wool and vertical rock wool board.
市场上防火岩棉板的主要区别在于纤维的物理分布。纤维分为分层和折叠，也称为水平和垂直纱线。防火岩棉板的水平线和垂直线的主要区别在于生产工艺的不同。
The main difference of fireproof rock wool board in the market lies in the physical distribution of fiber. Fibers are divided into layers and folds, also known as horizontal and vertical yarns. The main difference between the horizontal line and vertical line of fireproof rock wool board lies in the different production process.
水平法的主要生产工艺是通过离心力将高温熔体吹出，形成岩石表面纤维，纤维可堆放在交替室内的传送带上。丝绸耐火岩棉板达到一定厚度后，通过压力辊进入固化炉。在腔室法中，混合纤维分布在平面内，接头的密度和均匀性不好，影响了压板的性能和层间结合强度。岩棉保温板按单摆法或三维法岩棉生产工艺生产。摆锤法基于替代方法。通过改进的采棉方法，在采棉平台上采集薄岩棉层，并按一定层数和厚度放置摆锤。辊子在硫化炉中加压硬化，然后通过冷却、切割、包装和其他成品进行处理。这种方法提高了棉层和所含胶水的均匀性。由于铺设过程中的倾斜，纤维部分垂直分布，抗压强度和层间粘结强度提高。
The main production process of Horizontal method is to blow out the high-temperature melt through centrifugal force to form rock surface fibers, which can be stacked on the conveyor belt in the alternating chamber. After the silk Refractory rock wool board reaches a certain thickness, it enters the curing furnace through the pressure roller. In the chamber method, the mixed fibers are distributed in the plane, and the density and uniformity of the joint are not good, which affects the performance of the laminate and the bonding strength between layers. The rock wool insulation board is produced according to the rock wool production process of single pendulum method or three-dimensional method. The pendulum method is based on alternative methods. Through the improved cotton picking method, firstly, the thin rock wool layer is collected on the cotton picking platform, and the pendulum is placed according to a certain number of layers and thickness. The rollers are pressure hardened in a curing furnace and then processed by cooling, cutting, packaging and other finished products. This method improves the uniformity of the cotton layer and the glue contained. Due to the inclination in the laying process, the fiber part is vertically distributed, and the compressive strength and interlayer bonding strength are improved.
总之，水平钢丝与垂直钢丝岩棉板在抗拉强度、抗压强度和换算系数方面存在差异。一般来说，垂直羊毛岩棉带的抗拉强度是抗压强度的1-2倍。相同容重的水平块状毛条抗压强度相近，共振系数略低于水平毛条。垂直砂石面带可以克服水平砂石面抗拉强度低的缺点，满足外墙保温的使用。
In short, there are differences in tensile strength, compressive strength and conversion coefficient between horizontal steel wire and vertical steel wire rock wool board. Generally speaking, the tensile strength of rock wool is 1-2 times that of rock wool. The compressive strength of horizontal block top with the same bulk density is similar, and the resonance coefficient is slightly lower than that of horizontal top. The vertical gravel surface belt can overcome the disadvantage of low tensile strength of horizontal gravel surface and meet the use of external wall insulation.
