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 exterior wall insulation materials?

Extrusion board; this material will be better than the introduction of the benzene board, heat preservation is much stronger, so compared to higher than the price.

Q:What kinds of fire retardant coatings are there in steel structures?

The utility model can be expanded and expanded slowly when the fire is in place to form a dense and hard fireproof heat-insulating layer, and the fireproof layer has strong fireproof impact property, and the temperature rise of the steel is delayed, and the steel member is effectively protected. 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. There have been 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, double itrate alcohol, melamine as four fire retardant system, adding titanium dioxide, wollastonite and other inorganic refractory material, using 200# as solvent and solvent oil compound. All kinds of light steel structure, grid and so on, use this type of fire retardant coatings for fire protection.

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

EIA: it is a kind of inorganic thermal insulation mortar. It has many similarities with the performance of rock wool. It has good fireproof performance and good durability. It can be synchronized with the structure life. But its handle is better than rock wool, fire class A1, light capacity, low thermal conductivity, high tensile strength, good bonding effect. Can improve the working conditions of workers, harmless to construction personnel, easy construction, directly to the wall, without any binders, direct coating.

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:The classification of exterior wall insulation and its main categories

The second category is the engineering construction industry standards, external wall insulation engineering technical regulations. JGJ144 which includes five kinds of insulation system: the first is the EPS board exterior wall insulation system; second is the powder particles insulation slurry EPS exterior insulation system; third is the cast-in-place concrete wall of EPS board external insulation system; the fourth is a net cast system; fifth is the mechanical fixation of EPS steel wire the grid board exterior insulation system. With the existing external insulation insulation supporting standards, product standards and related engineering construction industry standards. The main supporting product standards are polymer based wall insulation glass fiber mesh; wall energy conservation project construction quality acceptance specification, that is, we know GB50411. Because most of these standards from 2003 to 2007 completed, but because of external wall insulation technology is developing very fast in recent years, the standard of life is short, basically all the standard in the revision, according to the development of technology, there are many standards are approved by the Ministry of construction, is being developed, the revision of the standard is JG149, the JG149 is the revision of the manuscript before the preparatory work. JG158 has just started the startup meeting and is preparing for the update.

Q:Advantages of exterior wall energy saving and environmental protection heat insulation coating

At present, there are many kinds of exterior wall insulation materials in the market, which can be divided into organic insulation materials and inorganic insulation 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..

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 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.

Q:Fireproof rock wool board can be used as firewall?

You need to know what material the firewall is made of What are its standards and requirements? What's the function of it? When you know all about it, you won't take a piece of board to make a wall!
