- Q:What do RH and DH stand for in refractories?
- DH :An agreement that allows strangers to build shared keys, originally invented by Diffie and Hellman.
- Q:Who knows what fire heat preservation material are there?
- 1 thermal insulation materials with class A combustion performance Rock wool, glass wool, foam glass, ceramic foam, foamed cement, perlite and other 2. thermal insulation materials with B1 combustion performance Specially processed extruded polystyrene board (XPS) / specially processed polyurethane (PU), phenol, powder polystyrene particles. Heat-insulating material with B2 termal insulation performance Fire resistance can be thoroughly sloved by combining molded expanded polystyrene (EPS), extruded polystyrene (XPS) and polyurethane (PU), polyethylene (PE) Hairong module with glass beads (and cooperating with vitrified micro bead inventor Liu Weihua), hope my answer will help!
- Q:How many fire endurance grades are the AAA fire resisting shutter divided?
- The different fire resistant levels of the building have different requirements of the fire endurance of the building component. According to the fire endurance, the fire doors can be divided into Class A, Class B and Class C fire doors with the fire resistances are not less than 1.20h, 0.90h and 0.60h. Even the fire resistant level of B can also use the first rate fire resistant door.
- Q:what textures of furnace refractories are good?
- Common ceramics use ordinary clay and high alumina bricks, as well as thermal insulation bricks, calcium silicate boards and fiber cotton. The vessels fired with potter's earth are called pottery, and the vessels fired with porcelain clay are called porcelain. Ceramic is generic term of pottery, stoneware and porcelain. The objects taking the two different types of clay as the raw materials, like, potter's earth and porcelain clay, and made through the technological process of ingredients, forming, drying and roasting, ect. can be called ceramics.
- Q:Can polystyrene foam color steel plate be used as decorative fireproofing material ?
- Polystyrene foam plastic can not be used as fireproofing material; polystyrene foam plastic is made up of polystyrene resin as main component, foaming?agent and other additives. It is a buffer material which is most widely used[1]. It is closed hole structure, so it has low water-absorbing quality and excellent water resistance; low density, about 0.015 ~0.03; good mechanical strength, excellent buffer?performance; good machinability, easy to be moulded; good dyeing property, thermal adaptability and anti-radiation; high dimensional accuracy, uniform structure. Therefore, it has a large share in external wall thermal insulation. But it will emit polluted styrene gas when burning. It is a kind of class B material in construction.
- Q:How to distinguish the fire resistant level of construction materials?
- There are 3 conditions for building components to reach fire endurance, namely: Loss of ability to support; loss of integrity; loss of fire insulation function. As long as one condition occurs, fire endurance is reached and the time before it is called fire endurance. 1), loss of ability to support: If the specimen bearing capacity and rigidity reduce, section area shrink, collapses or deformation exceeds specified numerical value because it cannot bear the load of original design under flame or high temperature, it loses the ability to support. 2), loss of integrity: It mainly refers to the thin wall separating component(such as stairs, windows,partitions, ceiling, etc.) burst or partially collapse under flame or high temperature, and penetrating?fracture or opening appears, and the reverse side even burn. For example, when the floor is under flame or at high temperature, the flame spread to the upper room, which indicates that the integrity has been damaged. 3), loss of fire insulation function: It mainly refers to that seperating components loses thermal insulation and excessive heat conduction. In experiment, if the average temperature of component unexposed surface exceeds 140 ℃, or if any spot at the unexposed surface exceed the initial temperature of 180 ℃, the component loses fire insulation function.
- Q:Which one is the best refractory material?
- o make it simple, you can kindle it, and observe the burning time. If there is a professional need to be accurate, then you can send it to the professional testing company. As far as I know, the Kebiao Company over the victory bridge, Qingdao can offer professional test. I hope my answer can help you, thank you, hope to be adopted.
- Q:Fire insulation and fireproof insulation board materials What is the difference in performance?
- What is the difference between fireproof insulation board and fireproof materials in their performance? Fireproof Materials prevents burning through insulating while others by chemical reactions. The overall heat conductivity coefficient of Insulation materials are generally lowered by thermal conductivity of the material itself and the structure of the material. Inorganic active insulation material uses ordinary cement, insulation stone, calcium powder, platycodon grandiflorum as the main raw material, produced after numerous tests with advanced production technology and chemical technology. Products features fire retardant,anti-aging properties and stable performance, low deformation coefficient, environmentaly friendly, compatible with the wall base layer and plastering layer. It has good security and stability and is as durable as ordinary buildings. Strong fire resistance: Fire insulation board is made of inorganic materials (cement), fireproofing level reaching to A1. As it does not burn, it is fireproof.
- Q:I am a manufacturer of refractory materials. I would like to receive some orders from abroad. I would like to know what foreign trade companies in Dalian place foreign orders abroad
- Dalian foreign trade companies are numerous, and fire prevention materials are also quite a lot
- Q:how to classify Insulating Refractory ?
- General materials have test reports, where fire rating is labled.
