What is refractory ?

Refractory refers to the temperature in degrees Celsius at which a conical specimen of refractory material can withstand the action of high temperatures without softening and melting under no load. However, refractories cannot be completely described by the definition of refractoriness, and 1580°C is not absolute. Yyrefractory refractory raw materials are a class of inorganic non-metallic materials whose refractoriness is not lower than 1580℃. Materials now defined whose physical and chemical properties allow their use in high temperature environments are called refractories. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, electric power and other industrial fields. They are used the most in the metallurgical industry, accounting for 50%-60% of total production.


The workability of refractory materials includes consistency, slump, fluidity, plasticity, cohesion, resilience, coagulation, hardening, etc.


Main products of refractory materials:

As a refractory manufacturer, Gongyi Yuying Refractory Co., Ltd. mainly produces refractory materials: shaped refractories and unshaped refractories; shaped refractories mainly include: high alumina bricks, clay bricks, corundum bricks, insulating fire bricks, etc. ; Unshaped refractories mainly include: refractory castables, ramming materials, refractory cement, bauxite, alumina powder, corundum and so on.


high alumina refractory bricks


Application of refractory materials:

Refractory materials are used in various fields of the national economy such as iron and steel, non-ferrous metals, glass, cement, ceramics, petrochemicals, machinery, boilers, light industry, electric power, and military industries, and are essential basic materials to ensure the production operation and technological development of the above industries. It plays an irreplaceable and important role in the development of high temperature industrial production. get more details from www.yyrefractory.com.

Is there any difference between the different colors of clear plastic roof sheets?

  PC lighting tiles are based on polycarbonate (PC) engineering plastics. And add UV anti -ultraviolet agents and other chemical auxiliary agents, which are made of today's advanced technology and equipment. It has a strong light transmittability and strong weather resistance. It can be used at -40 ° to+120 °. The resistance is 250 times that of ordinary glass. The flame retardant B1 level is obvious. It is widely used: agricultural greenhouses, garden breeding greenhouses, station terminals, waiting pavilions ceiling, factory warehouse commercial building roofs, etc. Clear plastic roof shingles usually come in clear or translucent colors that allow natural light to filter through. Of course, tinted options in colors like green, blue or gray are also available. Clear plastic roof sheets supplier china There are differences between the different colors of clear plastic roof shingles, mainly in the amount of light that is transmitted through the shingles.

Why ASA synthetic resin tile can be fireproof?

  ASA synthetic resin tile is a new type of building material, which is made of ASA (acrylic ester-acrylonitrile-butadiene copolymer) synthetic resin and other additives through high temperature and high pressure extrusion molding. The main reasons why ASA synthetic resin tiles can be fireproof are as follows: The flame retardant performance of the material itself: ASA synthetic resin tile is a kind of flame retardant material, which itself has good flame retardant performance and is not easy to burn. Adding flame retardant: In the production process of ASA synthetic resin tile, a certain amount of flame retardant can be added to improve its flame retardant performance and make it more flame retardant. Tile structure design: The tile structure design of ASA synthetic resin tile is reasonable, which can effectively prevent the fire from spreading. The joints between the tiles adopt a special design, which can effectively prevent the fire from spreading t...
