Q:What are the exterior wall thermal insulation materials?

Metal insulation material:Mainly aluminum and its products, such as aluminum plate, aluminum foil, aluminum foil, composite light plate, etc.. It uses the radiation characteristics of the material surface to obtain the heat insulation performance.Advantages and disadvantages: with this kind of surface characteristics of the material, almost do not absorb the heat on it, and the ability to radiate heat itself is also very small, this kind of material supply less, more expensive.

Q:How can the exhaust pipe of a gas water heater be insulated by going through the glass?

Therefore, the temperature of the inner pipe of the water heater is higher, but the outer pipe is not very high because the outdoor air is flowing.At the same time, the air is a poor heat conductor, so the actual temperature of the outer surface of the outer tube of the water heater is not very high. That is to say, no special heat insulation measures are needed when the exhaust pipe of the gas water heater passes through the glass.

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 types of insulation materials used in pipes and equipment?

In buildings, materials used to control the flow of heat inside the building are called heat insulation materials, and materials used to prevent outdoor heat from entering the room are called heat insulation materials. Insulation, thermal insulation materials insulation materials called duncan. The commonly used insulation materials can be divided into two categories: organic and inorganic. According to its shape, and can be divided into fibrous, porous, microporous, bubble, granular, layered and so on, the following are some of the more common materials are briefly introduced.

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.

Q:What kinds of exterior wall thermal insulation materials are there in Northwest China?

There are a lot of external insulation materials, including foam, mineral wool products, foam glass, expanded perlite insulation, powder particles insulation slurry EPS, spraying mineral cotton, foam cement insulation products, polystyrene particles, internal and external wall thermal insulation glazed hollow bead mortar and external wall putty and so on, you can according to the preferences and choose one or several price.

Q:External wall insulation rock wool board construction points and matters needing attention, know how much?

The production enterprise of rock wool board insulation system should have professional guidance in the construction process, and cooperate with construction units and site supervision to do construction quality control work.Material access must be in accordance with specifications, quantity and quality requirements, after acceptance of qualified to storage, and should be kept by hand, is strictly prohibited open-air stacking. Curtain wall rock wool board should be overhead damp proof piling up.

Q:Does water paint spray fire in underground space?

Waterborne paint itself is waterproof, unlike oil paint as security for.

Q:The difference between rock wool and mineral wool

Cotton like short staple fibers made from silicate melts, including slag cotton, rock wool, glass wool and ceramic fibers, generally only refer to the first two.

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
