quality Rock Wool Insulation Material & Rock Wool Board factory

01 In the field of architecture   Rock wool is an artificial inorganic fiber grade A non combustible insulation material. As a building insulation material, rock wool can reduce energy consumption in buildings, reduce noise pollution, delay the spread of fires, and do not produce toxic and harmful gases and droplets. It provides time for personnel to escape and reduces casualties. In the field of architecture, rock wool is widely used in the roofs, exterior walls, indoor partitions, ceilings, ventilation ducts, smoke exhaust ducts, floating floor slabs, etc. of newly built, renovated and expanded public buildings, civil buildings, and industrial plants.     02 Industrial sector   The porous structure inside rock wool can effectively hinder air flow and heat transfer. By using rock wool products for reasonable installation and coating of industrial equipment, it can effectively reduce the heat transfer of industrial equipment to the outside, reduce energy consumption losses in the production process of industrial equipment, improve energy efficiency, and further effectively utilize the energy supplied to industrial equipment during equipment operation, indirectly reducing carbon emissions. Rock wool is widely used in the industrial field in nuclear power plants, power plants, chemical plants, refineries, pulp mills, steel mills, and other industrial fields.     03 Maritime sector   In addition to architecture and industry, rock wool has excellent fire insulation and sound insulation properties, providing safe and comfortable working and living spaces for offshore platforms and various types of ships. Rock wool is widely used in the maritime field in decks, bulkheads, pipelines, floating floors, ceilings, etc.     04 Planting field   In addition to traditional insulation and fire prevention functions, the application of rock wool as a planting substrate in the field of planting has developed with the continuous maturity of soilless cultivation technology, and has a history of several decades. Rock wool matrix is widely used in the field of planting, including modern greenhouse planting, automated seedling cultivation, three-dimensional greening, plant walls, and home gardening.

The difference between rock wool and asbestos   1. Raw materials The raw materials for rock wool are basalt, dolomite, and various additives; The raw material of asbestos is natural inorganic crystalline mineral fibers, and the main ores are serpentine, hornblende, pyrophyllite, and brucite.   2. Production process Rock wool is made by melting raw materials at a high temperature of 1400 ℃ and then undergoing several processes; Asbestos is a fluffy and soft fiber made from natural ores that have been mechanically dispersed.   3. Usage Rock wool is generally directly used as a finished product in construction, pipelines, containers, vehicles, ships, etc; Asbestos is a semi-finished product, usually added as an auxiliary material to other materials to make asbestos rope, asbestos cloth, asbestos packing, asbestos board, asbestos tile, asbestos paper, etc.   4. Fiber diameter (carcinogenicity) The fiber diameter of rock wool is mostly 2-6 microns, which is an amorphous artificial fiber. During processing and use, the fiber splits into segments, changing from one fiber to two shorter fibers. The fracture of rock wool fibers does not affect the change in fiber diameter and is not easy to enter the lungs through the respiratory tract, so it is not harmful to humans and has no carcinogenicity; The International Agency for Research on Cancer (IARC), a subsidiary of the World Health Organization (WHO), has conducted carcinogenic tests on rock wool (IARC is currently recognized as an authoritative organization) and concluded that rock wool products do not have carcinogenic effects on the human body. The diameter of asbestos fibers is 0.02-2 microns. Due to the crystalline nature of asbestos fibers, if an asbestos fiber is subjected to external force, it will crack along the axis and become two finer fibers, and so on. If it does not break, it will become smaller fibers with a smaller diameter. The extremely fine asbestos fibers are easily inhaled into the human body, attached and deposited in the lungs, stimulating endometrial cells to cause lesions and leading to diseases such as lung cancer. This is why asbestos itself is harmless but can cause cancer. Nowadays, asbestos has been recognized as a carcinogen by the International Center for Research on Cancer, so many countries have restricted or prohibited the use of asbestos products. According to statistics from domestic scholars, "over 80% of modern people's lives are spent indoors." Good indoor air quality and building environment have a profound impact on people's physical health and work efficiency. Therefore, for most building materials, in addition to the safety of the materials themselves, it is also necessary to consider whether the formaldehyde content exceeds the standard and other issues. The country has certain standards for the formaldehyde release of rock wool products, so choosing rock wool products within the national standards can greatly reduce the potential health threats caused by excessive formaldehyde in building materials in indoor environments.

High rise buildings have a certain degree of enclosure, with complex internal structures and dense personnel. The higher the height, the greater the difficulty of escape and evacuation in the event of a fire. Therefore, it is necessary to attach great importance to the systematization and standardization of building fire prevention, especially for super high rise buildings. Data shows that in the first three quarters of 2021, the Fire Rescue Bureau reported 2808 high-rise building fires and 107 deaths nationwide. They account for 9.2% and 6.8% of the total number of building fires, respectively, an increase of 4% and 1.1% compared to the same period in 2020.     So, how can we reduce the hazards of high-rise building fires?   1: Using A-grade non combustible insulation materials Article 6.7 of GB 50016-2014 "Code for Fire Protection Design of Buildings" has clear provisions for building insulation and exterior wall decoration. The internal and external insulation systems of buildings should use insulation materials with combustion performance of Class A, and B2 insulation materials should not be used. B3 insulation materials are strictly prohibited. Rock wool is an A-grade non combustible insulation material that does not shrink, deform, produce droplets, or toxic smoke in the event of a fire. It is the first safety bolt for high-rise buildings to slow down the rapid spread of fires and buy valuable time for rescue efforts. Rock wool can be applied to different parts and structures of buildings, making them both energy-efficient and safe.   2: Setting up building fire protection facilities Building fire-fighting facilities commonly used include automatic fire alarm system, automatic sprinkler system, fire hydrant system, gas extinguishing system, foam extinguishing system, dry powder extinguishing system, smoke control and smoke exhaust system, safety evacuation system, etc.   Let's focus on the smoke exhaust system: In fire accidents, smoke is the main factor causing casualties in building fires. The smoke carries toxic gases and microparticles with high temperatures, posing a great threat to human life. The purpose of smoke exhaust systems is to timely eliminate a large amount of smoke generated by fires, prevent smoke from spreading outside the smoke prevention zone, ensure the smooth evacuation and safe refuge of personnel inside buildings, and create favorable conditions for fire rescue. Smoke prevention and exhaust in buildings are necessary conditions to ensure the safe evacuation of personnel inside the building.   2: Setting up building fire protection facilities Building fire-fighting facilities commonly used include automatic fire alarm system, automatic sprinkler system, fire hydrant system, gas extinguishing system, foam extinguishing system, dry powder extinguishing system, smoke control and smoke exhaust system, safety evacuation system, etc. Let's focus on the smoke exhaust system: In fire accidents, smoke is the main factor causing casualties in building fires.

What is noise   The commonly referred to noise pollution is caused by human factors. From a physiological perspective, any sound that interferes with people's rest, study, and work, as well as the sound you want to hear, is collectively referred to as noise. When noise has a negative impact on people and the surrounding environment, it forms noise pollution.       The hazards of noise   Noise can bring great harm to students' learning and life. Studies have shown that when studying in a noisy environment, without sound insulation and noise reduction measures, students will be affected by noise interference and miss about 25% of the teacher's lecture content. Faced with sudden noise interference, people need to spend 4 seconds reorganizing their focus.   Therefore, it is crucial to create a learning environment with sound insulation and noise reduction measures, which not only makes the student's living experience more comfortable, but may also be an important condition for upgrading to a "top student".     ① Sound absorption and noise reduction, improving sound quality Rock wool has excellent sound absorption and noise reduction performance. The material itself has a noise reduction coefficient (NRC) of over 0.85, which can effectively absorb noise in various frequency bands of low, medium, and high. The pore structure of rock wool fibers can consume the energy of sound waves, reduce the transmission of noise, and make it have excellent sound absorption characteristics. Not only does it isolate outdoor noise intrusion, but it can also remove noise and improve indoor sound quality. If silent rock wool is used in school buildings, it can reduce classroom reverberation, block the spread of noise outside the classroom, and provide students with a learning environment with clear sound quality suitable for quiet thinking.   ② Fire safety, easy to construct Compared to other sound insulation materials on the market, rock wool not only has sound insulation and noise reduction functions, but also has excellent fire and high temperature resistance, which can improve fire safety and prolong the escape time from fires. The three-dimensional structure of rock wool fibers ensures its stable mechanical properties, making it less prone to damage during transportation, installation, and use. It can be cut freely, making it easy to install and construct, and improving work efficiency.   ③ Low carbon and environmental protection, green campus In the design of the campus, it can reflect the determination and sense of responsibility of the school to achieve carbon reduction and promote carbon neutrality. The selection of building materials also requires environmental friendliness. At the same time, by using a multi energy complementary comprehensive energy system, recyclable materials, and modular building components, the carbon footprint generated during project construction and operation is greatly reduced, making it a truly green campus. Compared to other insulation materials, rock wool has a more positive impact on the environment and is an environmentally friendly material that is in line with sustainable development.

In today's homes, people go out day and back at night. Except for retired elderly people, most people have a similar daily routine. However, in recent years, a group of freelancers have emerged, such as anchor internet celebrities, stock speculators, and online store owners. These people who stay at home for a long time are mostly mental workers and are very sensitive to interference between neighbors. Compared to those who work at the company, they also create more residential noise.   Especially this year, due to the impact of the epidemic, a quiet and comfortable indoor life has become a rigid demand for almost everyone.       Quality sleep requires tranquility   Research has shown that noise is the most important external factor affecting sleep, and sleep deprivation caused by noise can seriously threaten human health, especially irregular and sudden noise. Lack of sleep can cause health damage such as insufficient rest of the cerebral cortex, weakened immunity, and brain dysfunction. During sleep, noise can cause problems such as increased arousal frequency, reduced sleep duration, fragmented sleep cycles, and decreased sleep quality.       Working from home requires quietness   There is a significant difference from daily activities such as watching TV, listening to music, and home entertainment. Working from home requires concentration and concentration, while the internal noise of the room and the activity noise between neighbors are the main interferences to working from home. These sounds are mostly sporadic and often unintentionally interrupt people's thoughts, forcing them to shift their attention and seriously affecting work efficiency.   Therefore, from the perspective of home life and office health, on the one hand, it is necessary to control the internal noise sources of the room, and on the other hand, it is necessary to improve the sound insulation and absorption effects of the walls.         Rock wool - a private sound barrier   Generally speaking, the larger the mass of a homogeneous material wall, the smaller the displacement caused by the action of air molecules on the wall, the smaller the amplitude of the wall, and the lower the amount of sound passing through. Therefore, in architectural design, soundproof materials such as rock wool are often used for filling to ensure good sound insulation and absorption effects between households.   Rock wool is a porous fiber inorganic material, with the internal air volume accounting for 90-95% of the entire surface volume, allowing air to freely enter and exit. When the air that propagates sound enters, the air molecules rub against the surface of the fibers, converting mechanical energy into thermal energy, resulting in a significant attenuation of amplitude. The macroscopic manifestation is that sound energy is absorbed and the sound level is reduced.   In addition, rock wool can also serve as a damping elastic layer for floor slabs, buffering impact strength, and thereby improving the sound insulation effect of floor slab impacts.   Creating a comfortable working and living environment from home requires technical measures such as reducing noise, improving sound insulation, and increasing sound absorption. The design standards, new materials, and management system play an indispensable role in the process of creating a sound environment.

1. Observe and feel with the naked eye. From the appearance, high-quality rock wool board has very fine fibers, soft and dense, with a brownish yellow color, low ball slag content, and is not easy to fall off. There is no obvious prickling sensation when touched by hand, and it is not easy to deform when pressed and stretched. However, from the appearance, inferior rock wool boards have coarse and hard fibers, a bright yellow color, a high content of ball slag, and are prone to slag dropping. There is a noticeable prickling sensation when touched by hand, and when pressed and stretched, it is prone to deformation and severe debris loss. The main reason for this difference is that the raw materials are different, and high-quality rock wool boards are mainly made of basalt, diabase, and other raw materials. After melting, the fibers thrown out are relatively delicate. However, low-quality rock wool boards mainly use blast furnace slag as raw material, and the fibers produced after melting are relatively thick and easy to break. The second reason is that the production process and quality of the production line are different. A high-quality rock wool production line will melt the raw materials more thoroughly, spin the fibers more finely and gently, and spray glue and hydrophobic agents to assist small materials more evenly and reasonably. However, low-quality rock wool production lines perform poorly in these production processes.   2. When purchasing rock wool boards, we must ensure that the seller provides a testing report and carefully review the testing data on the report. For example, rock wool bulk density, size error, thermal conductivity, hydrophobicity, water absorption, compressive strength, tensile strength, etc. These data are important indicators that affect the quality of rock wool. In addition, the testing report must be selected from a testing unit at or above the provincial level, which is good for being at the national level and more authoritative. It should also be stamped with a red seal to prevent counterfeiting!   3. On site factory inspection. If there is enough time, it is recommended that customer friends conduct on-site factory inspections to prevent dealers from impersonating manufacturers, using inferior products as good ones, and false advertising. If you really can't find time to go to the factory for inspection, we can provide you with samples of the same specifications and ensure that the quality of the samples is consistent with that of the bulk goods.
