Q:What are the exterior wall thermal insulation materials?

Inorganic insulation material:A mineral mineral wool, perlite, vermiculite, diatomite, gypsum, slag, glass fiber, wool, aerated concrete, foam concrete, pumice concrete and its products, chemical synthesis of polyester and synthetic rubber with polystyrene, PVC, polyurethane, polyethylene, urea formaldehyde plastics and foam rigid ester and its products etc..Advantages: this kind of material does not decay, high temperature resistance, partial moisture absorption, easy to burn, more expensive.

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: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 is the best sound proof cotton in the decorative plaster board partition wall? Mineral wool rock and glass wool.

Rock wool and glass wool on the overall performance of almost the same, are brittle fiber composition, you need to get a good sound insulation, you need to use high-density materials, usually 80KG per cubic meter of the use of more. The price range is 40-60 yuan per square meter. This material can cause skin allergies and dust can cause respiratory allergies. Therefore, construction should pay attention to the construction personnel physical protection, materials must be completely sealed to the wall inside. If it is a ceiling with holes, you must not use glass wool.

Q:Now, what are the new exterior wall thermal insulation materials?

At present do not know the new promotion is that kind, can only suggest you several, because of the advantages and disadvantages, in general, the insulation is not set fire, fire insulation, fire and insulation products prices high ridiculous.

Q:Does water paint spray fire in underground space?

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

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

Rock wool and slag cotton belong to mineral cotton, and they have many similarities in the production process, fiber morphology, alkali resistance, thermal conductivity and non combustibility.

Q:How about the appearance of glass wool, mineral wool and asbestos?

Glass wool belongs to a kind of glass fiber, it is a kind of man-made inorganic fiber. Quartz, sand, limestone, dolomite and other natural ore as the main raw materials, with a number of soda ash, borax and other chemical raw materials into glass. In the melting state, by means of external force, the system is thrown into flocculent fibers, and the fibers and fibers are made of solid intersection. They are intertwined with each other and show a lot of small gaps. This gap can be considered as a pore. Therefore, the glass wool can be regarded as a porous material and has good thermal insulation and sound absorption performance.

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 is the difference between ordinary slag wool rock wool board and basalt rock wool board?

Rock wool and slag cotton belong to mineral cotton, and they have many similarities in the production process, fiber morphology, alkali resistance, thermal conductivity and non combustibility. People usually referred to as mineral wool rock wool and slag wool, so easy as the two are the same thing, even thought that the slag wool color white, gray green wool is more than "pure", this is a misunderstanding. Although they are all mineral cotton, there are still some differences that can not be ignored. The main reason for these differences is the composition of the ingredients.
