Q:What are the common thermal insulation materials?

In architecture, it is customary to control the flow of heat through the houseMaterials called thermal insulation prevent the heat from entering the room from being called heat insulation material. Insulation, thermal insulation materials insulation materials called duncan. The commonly used insulation materials can be divided into two categories: organic and inorganic. In its shapeCan be divided into fibrous, porous, microporous, bubble, granular, layered and many other, here are some of the more common materials are briefly introduced.

Q:What are the kinds of fire door core board?

Inorganic fireproof insulating material, fire door core, such as rock wool, mineral wool, glass wool, aluminum silicate cotton, asbestos, expanded perlite, expanded vermiculite products, foam glass, microporous calcium silicate products. Inorganic materials are far better than organic materials and fire insulation performance and smokeless toxic performance, but there are some limitations, some non compressive degrees, must be attached to support carrier, carrier and brought fire and burning smoke toxicity problems, such as rock wool, mineral wool, glass wool, cotton, aluminium silicate asbestos is such; some high prices, the production of high energy consumption, such as foam glass, microporous calcium silicate in the case of such refractory; some itself is not high, moisture absorbent is large, such as cement or water glass based products, perlite cement or water glass based products, products such as vermiculite foam concrete is such, therefore restricted to varying degrees as the filling core material of the fire door.

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:Rock wool, EIA inorganic insulation mortar, polystyrene particles, polystyrene foam board advantages and disadvantages comparison?

Polystyrene foam board: polystyrene foam board is polystyrene resin as the main raw material, foaming agent made by foaming, with numerous closed microporous material. The utility model has the advantages of small density, small thermal conductivity, low water absorption, good sound insulation performance, high mechanical strength, high dimensional accuracy and uniform structure. But its flammability, combustion, release of toxic gases styrene, B3 grade materials. In the 3.15 exposure of fire accidents, polystyrene foam board accounted for a large proportion, the country has banned the use of.

Q:What are the differences between slag wool and rock wool?

Rock wool and slag wool, chemical composition and acidity coefficient comparison in our country, the main raw material for blast furnace slag slag cotton general or other metallurgical slag, the main raw material for rock wool basalt or diabase, the chemical composition of the differences between them are larger (

Q:What are the requirements for floor and exterior wall waterproofing in building construction?

The overall waterproof design of the exterior wall shall include the following contents: 1. Construction of waterproof engineering for exterior wall; 2. Selection of waterproof layer material; 3. Waterproof structure of joint sealing

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:The difference between rock wool and mineral wool

Originated in Hawaii. Rock wool products are high-quality basalt, dolomite as the main raw material, the high temperature above 1450 DEG after melting by four axis high speed centrifugal centrifuge international advanced fiber, and spray with a certain amount of binder, dustproof oil, water repellent cotton collector after collection, through the pendulum method, and three-dimensional method after cotton spreading curing, cutting, rock wool products form different specifications and applications.

Q:What are the composite thermal insulation boards?

Extrusion board, Extrusion board insulation effect is better, higher prices, but also easy to burn, complex construction process, the need to add mesh cloth.

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.
