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: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's the difference between glass fiber and mineral wool?

Referred to as mineral wool. With non flammable, no mildew, no borers and other properties. Made into felt, blankets, mats, ropes, plates and so on. Used as sound absorption, shock absorption and heat insulation material.

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:Why should the insulation board be spliced when it is installed?

Thermal insulation materials are generally used to guide heat coefficient less than or equal to 0.2 of the material. Thermal insulation material development is very fast, and in industry and building the use of good insulation technology and materials, often can get twice the result with half the effort. Each ton of mineral cotton insulation used in the building saves one ton of oil a year.

Q:What materials should be used for building energy saving? Why?

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:What are the composite thermal insulation boards?

Polystyrene particle thermal insulation slurry, this kind of thermal insulation material water absorption rate is higher than other materials, use must do anti crack waterproof layer. Anti cracking and waterproof protective layer material is made up of anti cracking cement mortar and composite glass fiber net, which can effectively control the crack of protective layer for a long time

Q:Exterior wall insulation putty powder construction needs to pay attention to what problems?

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. Plastering construction should meet the following requirements: rock wool board paste after surface treatment with plaster surface plate, scraping the mortar on the surface coated with a stainless steel spatula (thickness 1 ~ 1.5mm), and press the rock wool board surface fiber. Mortar should be configured in strict accordance with product instructions, configuration of the adhesive should avoid direct sunlight, and should be used within 2h.

Q:What are the building energy saving materials?

At present, China's common energy-saving insulation materials are mainly rock wool, glass wool, polystyrene foam, cement, polystyrene board, silicate composite insulation mortar.

Q:Fire retardant plywood does not belong to non-metallic refractory building materials

Materials are inorganic active insulation materials, foam, mineral wool products, foam glass, expanded perlite insulation, powder particles insulation slurry EPS, spraying mineral cotton, foam cement insulation products, vacuum insulation panel etc..
