Q: What are included in wall fireproofing material?: External wall thermal insulation materials are divided into A and B according to combustion level. Grade A is incombustible material, while grade B is combustible material. A few years ago, fires in CCTV building and Shenyang hotel resulted from grade B material. Currently grade A is usually used, and some are even cheaper than the grade B material. Grade A is roughly divided into insulation mortar, phenolic board, rock wool board, foam cement board, etc. Insulation mortar is quite good. It is easy and convenient to construct, has low cost, but the production is too simple and it is easy to fake. It is recommend to find a large manufacturer with complete formalities, such as provincial records of production, provincial records of use, city records, type test report at or above the provincial level, national fireproof report and design drawing collection of department of construction. Lack of any is unsafe. It is recommended to use mortar from Hebei Qizheng Haocheng New Building Material Co., Ltd. It is absolutely large manufacturer. MPC thermal mortar produced by it is recommend product of Department of Construction in Hebei Province!

Q: Who can introduce the difference between galvanized fireproof?coatings and steel structure fireproof materials?: Steel structure with heat galvanization has a process requirement, which is to spray fireproof coatings. Fireproof coatings have different functions and purposes from galvanized process. When the steel surface derusted, it generally needs to brush rich-zinc primer before spraying fireproof coating. Fireproof coating plan itself includes anticorrosion plan, and fireproof coating is just a layer of coating plans, which is an intermediate layer in general. Fireproof coating plan generally includes primer, fireproof coating and finishing paint. Some fireproof coatings can be directly painted on the bare steel elements without primer and finishing paint.

Q: How to hang the suspended brick in the refractory masonry?: First you can weld the metal fastener of the suspended brick and then hang up the brick.

Q: What's the refractoriness and how to measure the refractoriness?: Bottom each side length is 8 mm and upper side length is 2 mm. Under a certain temperature-rising speed, when heating, refractory's resistance to high temperature from melting is called refractoriness. The properties of cross section into an equilateral triangle and height is 30 mm. When it bends down until the vertex and chassis contact temperature is the refractoriness of sample. It bends due to the influence of its weight. Make the will-measured material into standard pyrometric cone.

Q: How is refractory material made?: It is made from carbon materials.

Q: Does refractory belong to metallurgical auxiliary materials?: Refractory includes metallurgical auxiliary materials.

Q: Graphite and other carbon materials may be oxidized to CO or CO2 at high temperatures. But why can they be refractories?: There is no contradiction for this. Any substance can be combustible, but different materials have different ignition points.There are many types of graphite. Pyrolytic graphite has a much lower ignition point. Therefore, as long as it reaches at a certain temperature, it can convert into graphite. Mostly, in practical applications (such as brake pads will add a certain amount of graphite), graphite is required to have refractoriness of below 1000 ℃. Graphite can serves as both the combustible and refractory material. So, it can be used as a fire-resistant and high-temperature-resisrant material because graphite (lamellar graphite) has a ignition point of at least 3000 degrees in an oxygen free condition. The above information is for reference only and is offered by Xin Ruida Graphite Company.

Q: What types of steel are silicious quicksand and chromium quicksand used in respectively?: Chromium quicksand can be used in steel-making process that has longer refining time like LF, VD and RH, in stainless steel drainage and thin plate drainage agent. Silicious quicksand is used in short steel-making process, process that is less than 45 seconds or process without refining. You can consult Hua Heng for details or inspect it by yourself.

Q: Fire insulation and fireproof insulation board materials What is the difference in performance?: Fireproof materials and insulation materials, refractories not the same thing, but some insulation materials are fire resistant and refractory. Fireproof material is a synthetic material characteristics of fire resistance or the material itself is a high temperature resistant, flame-retardant. Fireproof materials are mostly used for construction, playing an important role in fireproof today in various forms.
