What is the role of rock wool produced by rock wool equipment

What is the role of rock wool produced by rock wool equipment The rock wool board produced by the rock wool equipment is calcined by high temperature melting, and the main material is basalt. Basalt has incomparable advantages in the construction industry, and rock wool board also well inherits these advantages. In the construction process, rock wool board is mainly used for insulation of walls, roofs and houses, and wall insulation is the main use of modern rock wool board. The rock wool board produced by rock wool equipment is particularly suitable for on-site assembly, room height increase, long-span building structure and energy-saving wall reconstruction of old buildings, and has strong seismic strain capacity and other related characteristics. Rock wool board produced by rock wool equipment has the advantages of low thermal conductivity, good permeability and high combustion performance. It can be applied to energy conservation and thermal insulation projects of new, expanded and rebuilt residential and public building exterior walls, including exterior wall thermal insulation, opaque curtain wall thermal insulation and EPS external thermal insulation system. Marine waterproof rock wool insulation board is added with waterproof additives in production, which has good moisture-proof performance. Marine rock wool board is used for ship thermal insulation and fireproof partition; Water repellent rock wool board is used for vehicles, mobiles equipment, cold storage engineering, air conditioning pipelines and heat preservation, fire prevention and damp proof applications in humid environments. Rock wool products use basalt as the main raw material. After melting at high temperature (temperature greater than 1450 ℃), they are made of inorganic fibers by high-speed centrifugal equipment, and then added with special adhesives and dust-proof oil. The roller cotton is used to collect the belt cushion, and the special equipment is used to change the fiber arrangement. Rock wool fibers are arranged into a three-dimensional chaotic structure. The last one is a new type of lightweight thermal insulation material made of curing equipment. Then, according to different uses, we can produce rock wool board, rock wool felt, rock wool shell and other products. Rock wool is mainly used for insulation of walls, roofs, doors and floors in building insulation, among which wall insulation is important. Industrial rock wool insulation is mainly applied to industrial equipment such as industrial storage tanks, boilers, heat exchangers, etc. It can also be used for insulation, fire resistance and flame retardancy of ship bulkheads and suspended ceilings. Rock wool felt is mainly used for thermal insulation of equipment with complex shape and high temperature. Rock wool insulation tape is widely used for insulation of large diameter pipes, tanks and other equipment.

Rock wool centrifuge accessories manufacturers share several aspects to consider when purchasing centrifuges

Rock wool centrifuge accessories manufacturers share the working principle of centrifuge During the high-speed rotation of the centrifuge, due to the movement of centrifugal force, the solid substances suspended in the liquid form sediment. That is to say, the part with large mass or volume in the body fluid moves towards the direction with large turning radius, and the part with small mass or volume is deposited at the place with close turning radius. We mentioned the concept of centrifugal force above. Centrifuge is a machine that generates centrifugal force, which is related to rotor radius, rotating speed and sample quality. F=RMO2 (F: centrifugal force: r: radius: m: sample mass: w: rotating speed), centrifugal force is one of the important parameters for measuring centrifuge, and also one of the standards for centrifuge grade difference. The centrifuge provides high speed and centrifugal force of the centrifuge in the factory. We all know that the radius of the rotor and the mass of the sample remain unchanged during operation, and only the speed can be changed by adjustment. Therefore, we are often used to describing centrifuge with turnover rate. High speed centrifuge, high speed centrifuge, etc. Rock wool centrifuge accessories manufacturers talk about the classification of centrifuges 1. According to the speed, it can be divided into low-speed centrifuge, high-speed centrifuge and high-speed centrifuge. 2. According to the temperature requirements, it can be divided into ordinary centrifuges and refrigerated centrifuges. 3. According to different rotors, it can be divided into horizontal rotor centrifuge, angle rotor centrifuge and enzyme dial rotor centrifuge. 4. According to the size of the centrifuge, it can be divided into floor type centrifuge, desktop centrifuge, handheld centrifuge, etc. 5. According to the grade of centrifuge, it can be divided into ordinary centrifuge and precision centrifuge. Ordinary centrifuges have few functions and are inaccurate in speed and capacity. For example, the large speed of an ordinary centrifuge is 5000 rpm, but the actual speed cannot reach 5000 rpm. This centrifuge is only suitable for general centrifuge work, such as serum separation, urine concentration, etc. The function, speed and capacity of the precision centrifuge are accurate. It is suitable for PCR experiments, blood component separation (mostly used in blood stations) and other experiments with high requirements for centrifuges. The purchase of ordinary centrifuges is mainly selected from two aspects: speed and capacity according to the workload.

About the maintenance and troubleshooting of laboratory centrifuge

Rock wool centrifuge accessories manufacturers take ordinary centrifuges as an example to briefly introduce maintenance and repair. There are many kinds of centrifuges. We can divide them into low-speed centrifuges, high-speed centrifuges and high-speed centrifuges according to the speed. According to the temperature requirements, it can be divided into ordinary centrifuges and refrigerated centrifuges. According to the volume of centrifuge, it can be divided into floor type centrifuge, desktop centrifuge, handheld centrifuge, etc. Manufacturers of rock wool centrifuge accessories talk about the composition of the centrifuge An ordinary centrifuge consisting of a motor, a rotary table, and a governor. It is composed of casing, base, etc. Among them, the motor speed is higher under light load, but the speed drops sharply with the increase of load. 1. Speed: Centrifuges can be divided into low-speed centrifuges (less than 10.000rpm/min) and high-speed centrifuges (10.000rpm/min-30.000rpm/min) according to high speed 2. Capacity: The number of sample tubes required for centrifuges, the capacity required for each sample tube, and the total capacity of centrifuges. To put it simply, the total capacity of centrifuges=the capacity of each centrifuge. The total capacity is consistent with the size of the workload. 3. Rotor: The rotors of centrifuges are roughly divided into two types. Horizontal rotor: during rotation, the basket is horizontal, at right angles to the hinge, and the sample is deposited at the bottom of the centrifuge tube. Angle rotor: the centrifuge container is at an angle with the rotating shaft, and the sample is deposited on the side wall near the bottom and bottom of the centrifuge tube. Select "horizontal rotor" to concentrate the separated samples at the bottom of the centrifuge tube, and select "angle rotor" to concentrate the samples at the bottom and bottom side wall of the centrifuge tube. There are also special experiments or special samples that need special rotors, such as large capacity baskets (mostly applicable to blood stations), enzyme labeled rotors, slide rotors, PCR rotors, tube rack rotors, capillary rotors, etc. The rotor has a fixed specification, which is combined with the capacity of the centrifuge. For example, the 12 * 5ml angle rotor determines both the rotor type and the centrifuge capacity, so the selection of the rotor is very important.
