Product Description:

Density: 60kg-200kg/m3




Rock wool board is made of select fine basalt as the major materials which is pulled into 4-7µ non-continuous fibers after melted by adopting advanced international four-roller centrifugal cotton-making procedures and adding a certain of adhesives, dust laying oil and water repellent into rock wool fibers. It can be made into products series with different density according to various uses through the technology of sedimentation, solidify, cutting and etc.

Q:What is the heating tube cotton insulation material itch on the body?
Commonly used raw materials are iron, phosphorus, nickel, lead, chromium, copper, manganese, zinc, titanium and other slag. Mainly used as insulation material and sound-absorbing material. Iron packing materials can also be used. Slag cotton is made of industrial waste, slag (blast furnace slag or copper slag, aluminum slag, etc.) as the main raw material, by melting, using high-speed centrifugation or injection process, such as cotton filamentous inorganic fiber. It has the characteristics of light weight, small thermal conductivity, no burning, mothproof, cheap, corrosion resistance, good chemical stability, good absorption performance. It can be used for building insulation, sound absorption, sound insulation, oxygen generator and cold storage, cold insulation and insulation of various thermal equipments.
Q:Protective clothing is glass cotton wool type
Rock wool is mainly a small number of fibers, more harmful to the human body, so it is recommended that operators wear protective clothing in operation.Pure textiles, natural fibers, cotton, hemp, wool, silk, chemical fiber, polyester, viscose, nylon, nylon, spandex, polypropylene fiber, Teflon, etc.. A blended fabric is a fabric woven from two or more of the above materials. Blended fabric is more suitable for the fabric of work clothes. According to the different personal style structure and loose. Before and after the open. Open cover and bare. Early and open. Then the body and in vitro.
Q:What material is fast heated and kept warm?
The gap between the heating tube and the aluminum tube is filled with a heat conductive insulating elastic rubber, so that the heat can be rapidly transferred to the aluminum tube.Conductive heat insulation elastic rubber adopts silicon rubber base material, boron nitride, alumina and other ceramic particles as filler, the heat conduction effect is very good. Under the same conditions, the thermal impedance is smaller than that of other thermal conductive materials. Having a soft, clean, no pollution, high insulation and radiation characteristics of glass fiber provides good mechanical properties to reinforcement, anti piercing, shear resistance, tear resistance, with conductive pressure-sensitive adhesive.
Q:Is it dangerous to make mineral cotton mattresses?
Modern mattresses are generally not a single component, mostly compound.
Q:Does water paint spray fire in underground space?
NeededWater based brand fire retardant paint thickness is determined by base material, such as wood, steel structure, etc.:1. ultra thin structure fire retardant coating (0-3mm)2. thin steel structure fire retardant coating (3-7mm), fire-resistant 2-5h3. thick steel structure fire retardant coating (7-45mm), applicable to high-rise civil buildings, columns, general industrial and civil construction, fire up to more than 3H4. mineral cotton fire retardant insulation coating
Q:What is the best sound proof cotton in the decorative plaster board partition wall? Mineral wool rock and glass wool.
At present, the market is the best sound effect is said to be gradient sound-absorbing cotton, as well as high barrier sound felt. The price is relatively high, the price range is 55-80 yuan per square meter. The advantages of its products are more environmentally friendly, first of all, the construction will not cause skin itching. No emissions. It won't be pulverized. The sound absorption effect is reflected in the full frequency silencing, and has a good reduction effect on low frequency, intermediate frequency and high frequency sound. High barrier acoustic felt is reflected in its high damping performance. It can effectively restrain the sound propagation caused by resonance when it is attached to the thin plate. Usually relatively high-end, or official sites are more respected.
Q:What are the building thermal insulation materials in general?
Qinglong hollow glass micro bead heat insulation technology is composed of hollow glass beads inorganic insulation mortar, impermeable crack mortar, alkali resistant fiberglass mesh cloth (or galvanized steel mesh) is composed of three parts, the core part is hollow bead mortar, thermal insulation mortar insulation for the past, empty valley clefts and low strength. Our company in recent years development and improvement, through the selection and adjustment of raw materials imported additives were modified to form a double micro structure inside the product, the material has the characteristics and functions of lightweight plastering mortar, excellent thermal insulation, heat insulation performance of the material is stable, excellent fireproof performance, convenient construction, is at present, the products of similar products.
Q:What are the types of insulation materials used in pipes and equipment?
Mineral wool is the industrial waste slag as main raw materials by melting, cotton like insulation material made by injection method and centrifugal method: cotton is a natural rock as raw material is made of mineral wool. The commonly used rock such as Xuan Wuyan, diabase, amphibolite etc..Mineral wool characteristics: mineral cotton and products is a high-quality insulation materials, has more than 100 years of production and application history. The utility model has the advantages of light weight, heat preservation, heat insulation, sound absorption, good chemical stability, no burning and corrosion resistance, abundant raw material sources and low cost:Main use of mineral cotton: its products are mainly used in the walls of dry buildings, roof, ceiling and other insulation, insulation and sound absorption, but also made of waterproof felt and pipe sleeve.
Q:Exterior wall insulation putty powder construction needs to pay attention to what problems?
When the market holds 90% of the organic thermal insulation material at a standstill, as the fire protection level of the exterior wall insulation, inorganic materials, rock wool has ushered in an unprecedented market opportunity. Therefore, when using rock wool board, there are some we need to understand. Rock wool board insulation system for energy-saving insulation project construction should be in accordance with the review of qualified construction drawing design documents and approved by the project for energy-saving insulation project construction plan.
Q:Advantages of exterior wall energy saving and environmental protection heat insulation coating
Although the market is rich in exterior wall insulation products, but inorganic thermal insulation materials in addition to A-class fire retardant performance and good insulation effect, but also has excellent insulation system structure without network. In simple construction, and buildings with life, water resistant anti crack and anti hollowing fields occupy an increasingly important position.
