如今的高品質(zhì)耐火巖棉板主要由玄武巖和其他天然礦石制成。熔融后，將的四輥離心制棉工藝和高溫玄武巖羊毛溶液放入4~7μM的不連續(xù)纖維中。然后在巖棉纖維上加入一定量的粘合劑、防塵油、少量自制、運(yùn)輸、硬化、切割等工序，根據(jù)用途制成不同密度的系列產(chǎn)品。接下來(lái)我們將介紹水平巖棉和垂直巖棉板之間的差異。
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.
市場(chǎng)上防火巖棉板的主要區(qū)別在于纖維的物理分布。纖維分為分層和折疊，也稱(chēng)為水平和垂直紗線。防火巖棉板的水平線和垂直線的主要區(qū)別在于生產(chǎn)工藝的不同。
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.
水平法的主要生產(chǎn)工藝是通過(guò)離心力將高溫熔體吹出，形成巖石表面纖維，纖維可堆放在交替室內(nèi)的傳送帶上。絲綢耐火巖棉板達(dá)到一定厚度后，通過(guò)壓力輥進(jìn)入固化爐。在腔室法中，混合纖維分布在平面內(nèi)，接頭的密度和均勻性不好，影響了壓板的性能和層間結(jié)合強(qiáng)度。巖棉保溫板按單擺法或三維法巖棉生產(chǎn)工藝生產(chǎn)。擺錘法基于替代方法。通過(guò)改進(jìn)的采棉方法，在采棉平臺(tái)上采集薄巖棉層，并按一定層數(shù)和厚度放置擺錘。輥?zhàn)釉诹蚧癄t中加壓硬化，然后通過(guò)冷卻、切割、包裝和其他成品進(jìn)行處理。這種方法提高了棉層和所含膠水的均勻性。由于鋪設(shè)過(guò)程中的傾斜，纖維部分垂直分布，抗壓強(qiáng)度和層間粘結(jié)強(qiáng)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.
總之，水平鋼絲與垂直鋼絲巖棉板在抗拉強(qiáng)度、抗壓強(qiáng)度和換算系數(shù)方面存在差異。一般來(lái)說(shuō)，垂直羊毛巖棉帶的抗拉強(qiáng)度是抗壓強(qiáng)度的1-2倍。相同容重的水平塊狀毛條抗壓強(qiáng)度相近，共振系數(shù)略低于水平毛條。垂直砂石面帶可以克服水平砂石面抗拉強(qiáng)度低的缺點(diǎn)，滿足外墻保溫的使用。
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.
