Q: which kind of material should be used in fireproofing cabinet?
Natural stone,marble. advantage: Colorful, soft texure, natural and diverse texture, easy to cut or engraving molding. Disadvantages: Because it is a natural formation, tiny loose crackle is easily folded, because the stone is porous material structure, if sewage and waste water permeate in the structure in the process of production, transportation or construction, it's difficult to clean and easy to crack. In daily cleaning, it is inevitable that there will be some residue left, and dirt is filled into crack under the wiping of rag and becomes a breeding ground for bacteria. 2, granite. advantages: Granite has big density and high hardness, with wear-resistant surface, it's one of the most common materials for family decoration. Compared with natural marble, it can be used in the materials of kitchen countertops, and granite has good anti-bacterial regeneration ability. Disadvantages: As the cabinet table material, natural stone is usually not very long, so in order to produce a long overall table (especially U-shaped, L-type table), it will certainly exist joints, which are also easy to hide dirt. 3, artificial stone. advantages: Artificial stone has richful lines and colors, and it can be comparable to stone, it's non-toxic, non-radioactive, easy to clean, and can be truly seamless splicing. it belongs to economic environmentally friendly material. Disadvantages: Artificial stone belongs to the processing industry, and has low technology requirements, The inferior products of many small companys are fulled in the market and damage customers' interests. There exist faded color,poor aging resistance,oil stain and other issues in affordable products.
Q: What dose the fireproof and thermal insulation material include?
It includes A1: Non-combustible inorganic monomer; A2 Non-flammable organic compound, namely composite material; A3 Modified phenolic fireproof materials.
Q: How to determine the fire resistance rating of the aluminium-plastic?panel?
Class A incombustible and thermal insulation material: inorganic active wall thermal insulation material, cement foam insulation board, glass bead thermal mortar, rock wool board, glass wool board, foam ceramics, etc. With many characteristics of low density, low thermal conductivity, high pressure bearing capacity, convenience of construction, economy and durability, A class incombustible material is widely used as thermal insulation material for heat pipelines, thermal equipment, other industrial pipe-line equipment and industrial buildings, and thermal insualtion and sound absorption material for the building envelop of industrial and civil buildings. Because of good thermal stability, it is more often used as fire-proof and protective coating material of the steel structure.
Q: What's the poured refractory material?
According to its category, raw material of basic refractory: Mainly magnesite (magnesia), dolomite, lime, olivine, serpentine, high alumina material (sometimes neutral); main neutral raw material: chromite, graphite, silicon carbide (artificial).
Q: What is high alumina refractory?
High alumina refractory: High alumina refractory products, with high refractoriness, compressive strength and refractoriness under load, it is used for masonry of a variety of large-scale blast furnaces such as steel furnace, air heating furnace and electric furnace, and for high-temperature parts of thermal equipment like rotary?kilns.
Q: which kind of refractory is commonly used in the industry
Therefore it is known as special fire-resistant materials, such as yttria, high alumina raw material (sometimes neutral), olivine,which is used for alkalinity furnace, dolomite, and we roughly divided into several categories, beryllia, cerium oxide, these materials have a strong alkaline slag resistance, thorium oxide, lime, serpentine, which is picked from these refractory raw materials. the raw materials of basic refractory materials are mainly magnesia clay and titanium oxide, but because not many sources of raw materials, it can not be widely applied in the refractory industry, and we can analyze which kind of materal is processed by the pulverizer. There are many kinds of refractory materials, rotary?kiln can only be used in particular circumstances. These materials have a variety of slag resistance at different degrees. the main material of special refractories is zirconium oxide. the refractory clay is the most basic and most widely used raw material in the refractory industry.
Q: Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?
Why is the apple screen so small?
Q: Does anyone know about the A-level fireproof materials?
A-level decorative integrated plates of thermal insulation, water- and fire-proofing mainly can prevent fire and insulate heat with A-level fireproofing glass fiber as thermal insulation materials. The classification of A1-level external wall materials of thermal insulation, fire- and water-proofing: First, external wall thermal insulation materials: 1. silicate?thermal?insulation?materials 2. gelatine powder polyphenyl granules 3. steel wire gauze picking cement cystosepiment (grs board) 4. extruded sheets; Second, roofing materials: 1. xps extruded sheet 2. EPS foam board 3. perlite and perlite brick 4, vermiculite and vermiculite bricks; Third, heating and air conditioning materials: Polyurethane, rubberplastic sponge, polyethylene, polystyrene foam, glass wool, rock wool; Four, steel structure materials: Polystyrene, extruded sheet, Polyurethane board, glass wool roll mat, etc.
Q: What is the the best matching ratio of refractory cement?
Refractory cement is very easy to use. Add some water and mix, and it will harden. Generally there is no need to add other binding agents, but you can add some refractory aggregate and powder. If you use only refractory cement, it will produce a lot of cracks after high temperature. Generally refractory cement can withstand temperature of about 1300 degrees. Refractory cement can be used together with ordinary sand, and the ratio of cement and the sand is about 30 percent.
Q: Classification of porosities in refractories and their effects on properties
The pores in refractory include open pores, through pores and closed pores.
