Q:Is it dangerous to make mineral cotton mattresses?

Modern mattresses are generally not a single component, mostly compound.

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

The current gas water heater exhaust pipe does not require special thermal insulation when it passes through the glass.

Q:Is the calorimeter for building materials calorific value?

Calorific value calorimeter for building materials is used to determine the calorific value of building combustible materials such as stone, wood, concrete, and even dispersed mineral wool and polymers.In the standard set / group under the condition of oxygen nitrogen calorimeter specimen is placed in a certain quality of a constant volume, in order to test the temperature rise test as the foundation, considering all the heat loss and latent heat of vaporization, heat of combustion calculation sample.

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

Experts from authoritative institutions of Beijing Haina LIAN inorganic fiber spraying technology Co., Ltd. development of ultra-fine inorganic fiber spray identified, it is for the further development of the enterprise is undoubtedly a new impetus. I learned that the evaluation results, both for the enterprise is also happy, for the enterprise how to further enhance their ability of research and development and to further explore this, more hope that the enterprises can take the assessment results in the East, as the struggle to make "Heiner fertility LIAN" on the floor again!

Q:What is the difference between high-density rock wool board and hard rock wool board?

It can be used in the area of flat and big curvature radius, such as tank, boiler, large steel structure, external thermal insulation of glass curtain wall and so on. With aluminum foil, it can meet the needs of insulation and water vapor barrier of HVAC, air duct and cooling and heating pipe, as well as the requirement of building insulation. Make the room cool in summer and warm in winter and comfortable in all seasons.

Q:Does water paint spray fire in underground space?

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

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 requirements for floor and exterior wall waterproofing in building construction?

The joining of different structural materials shall be made of salt resistant fiberglass mesh or hot galvanized galvanized wire mesh of not less than 150mm on each side for anti cracking strengthening treatment

Q:What are the properties of fire-resistant coatings for steel structures?

Ultra thin structure fire retardant coating refers to the coating thickness of 3mm (including 3 mm) less than, decorative effect is good, high temperature can expand foaming, fire-resistant limit is generally less than 2 H steel structure fire retardant coating. This kind of fire retardant coatings for steel structures is generally solvent system, bonding strength, weathering has good water resistance, good leveling, good decorative features such as superior; subjected to fire slow expansion foam fire insulation layer to form a dense solid, the fireproof layer has a strong impact resistance, the temperature rise of steel delay, effective protection of steel member. Ultra thin intumescent steel structure fire retardant coating can be sprayed, brushed or rolled. It is generally used in building steel structures with a fire resistance requirement of less than 2 h. At present, there has been a fire resistance to meet or exceed the new ultra-thin fireproof coating for steel structure of 2 varieties of H, it is mainly based on the special structure of the poly methyl acrylate or epoxy resin and amino resin, chlorinated paraffin, compound as base adhesive, with high degree of polymerization of ammonium polyphosphate, melamine and pentaerythritol, double as the fire retardant system, adding titanium dioxide, wollastonite and other inorganic refractory material, using 200# as solvent and solvent oil compound. At present, all kinds of light steel structure, grid and so on, use this type of fire retardant coatings for fire protection. Because this type of ultra-thin fireproof paint coating, making use of thick and thin fire retardant coating for steel structure is greatly reduced, thereby reducing the total cost of the project, the steel structure has been effective fire protection, is currently promoting varieties on the market.

Q:What are the advantages of inorganic fiber spraying in construction engineering?

The company has professional inorganic fiber spraying construction qualification, can undertake a variety of insulation works, the main products of the company are: a rigid polyurethane foam composite board, polyurethane hard foam coating, inorganic fiber coating, glass wool and rock wool board auxiliary materials. Professional undertake spraying level external wall thin plastering system thermal insulation project.
