Rock wool is a mineral inorganic fibrous material with excellent and distinguished properties and characteristics. It is efficiently applied in all fields of thermo-acoustic insulation; furthermore it is used in many industries and agricultural activities. It is water proof rock wool.

Q:What are the building energy saving materials?: Glass wool is second kinds of products of mineral wool, with silica sand, limestone, fluorite and other minerals as the main raw material, by melting method and centrifugal method, using flame or high energy gas blowing process, the molten glass liquid made of inorganic fiber. Glass wool products have good thermal insulation, heat insulation, sound absorption, non burning, corrosion resistance and other properties. They are widely used in building, piping, storage tanks, boilers, aircraft, ships and other parts of the insulation, heat insulation and sound absorption.

Q:Why should the insulation board be spliced when it is installed?: The EPS plate shall be bonded in a vertical arrangement and the vertical seam shall be staggered along the line. Insulation board construction fault seam stitching truth with brick walls are brick seam is a reason for strong security.

Q:What are the properties of fire-resistant coatings for steel structures?: Thin coating steel structure fire retardant coating refers to the coating thickness of more than 3mm, less than or equal to 7 mm, with certain decorative effect, high temperature expansion and thickening, fire resistance within 2 H steel structure fire retardant coating. The fire retardant coating for steel structure is made up of suitable water polymer as base material, compounded with flame retardant compound system, fireproof additive, refractory fiber, etc. the principle of fire protection is super thin. For this kind of fire retardant coating, the water borne polymer must have good adhesion, durability and water resistance. Its decorative properties are better than those of thick fireproof coatings, which are inferior to those of super thin steel structure fire retardant coatings. The average fire resistance is within 2 h. Therefore, spraying construction is often used in steel structure fire protection engineering which is less than 2 h fire resistance limit. This kind of products occupy a large proportion in a period, but with the emergence of ultra-thin steel structure fire retardant coating, its market share is gradually replaced.

Q:What are the types of insulation materials used in pipes and equipment?: Glass wool is a fibrous material made from the melting of glass or crushed glass. It consists of two kinds of short cotton and superfine cotton.Features: glass wool can maintain good insulation performance under high temperature and low temperature; has good elastic restoring force; has good acoustic performance of acoustic noise. Have good sound-absorbing effect; good chemical stability, no aging performance unchanged, thickness, density and shape can be processed according to user requirements.Main applications: short cotton is mainly made of glass wool felt and felt. It is used for heat insulation and sound insulation of buildings, heat preservation and sound insulation of ventilation and air conditioning equipment. Superfine cotton master

Q:What material is fast heated and kept warm?: Heat the heating tube and the aluminum tube with the heat preservation material.There are many kinds of insulation products, including foam plastics, mineral cotton products, foam glass, expanded perlite thermal insulation products, rubber powder, EPS granule insulation paste, mineral spraying cotton and foamed cement insulation products.

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:8cm what is the sound volume of the soundproof cotton?: Because of the so-called insulation cotton when used alone is actually does not have the sound insulation function, because the so-called cotton insulation such as rock wool, mineral wool, glass wool and other characteristics are fluffy texture or fiber porous, and this kind of material is not sound barrier penetration, but can play a very good sound absorption effect weakens the acoustic reflection.But only on the insulation, the material must be able to reflect the acoustic absorption and consumption, thereby reducing the sound transmission coefficient, which passes through the material transfer to another space energy greatly weakened, and thus play a sound effect.

Q:How can the exhaust pipe of a gas water heater be insulated by going through the glass?: Gas water heater exhaust pipe are now dual structure: the inner tube is the exhaust pipe, the fan will strong combustion exhaust water heater forcibly discharges the indoor air inlet pipe; the outer tube is, the outer air (oxygen) gas suction water heater for combustion.

Q:Exterior wall insulation putty powder construction needs to pay attention to what problems?: Rock wool, also called asbestos, is a kind of mineral cotton. It is made of natural rock and mineral and is made of fluffy, short and fine fiber. Rock wool, that is, a kind of exterior insulation material

Q:What are the kinds of fire door core board?: Organic thermal insulation material, fire door core is such as EPS (foam polystyrene), XPS (extrusion foaming polystyrene), foam PVC, foam PE, foam PUR and sponge rubber as raw materials and other products. But because of flammability and combustion of organic materials to produce VOC, hinder the application of these materials, this also appeared over the pursuit of improve flame retardant properties of organic materials, and enhance the level of fire safety phenomenon, it not only greatly increased the cost of materials, at the same time as the non environmentally friendly flame retardant are on fire the process will increase the amount of smoke and smoke toxic materials, fire may bring greater harm, so the organic material as the core material of the fire door is not desirable.
