Best Plastic Refractory Buying Guide

2023 Best Plastic Refractories Guide

Have you ever heard of plastic refractory? Are you curious about plastic refractories? Fireramo has compiled the most comprehensive guide to understanding plastic refractories, including a basic introduction to plastic refractories, the pros and cons of plastic refractories, applications for plastic refractories and considerations for buying plastic refractory.

What is plastic refractory?

Plastic refractory is also known as refractory plastic. It is a kind of monolithic refractory material with high plasticity in a long period of time, which is in the form of soft mud paste.

Composition of plastic refractories

Plastic refractories are composed of refractory aggregate, powder, binding agent and plasticizer, of which refractory aggregate includes clay clinker, high alumina clinker, corundum aggregate and so on. The bonding agent has clay bonding, water glass bonding, phosphoric acid or aluminum phosphate bonding, aluminum sulfate bonding and so on. Plastic refractories are characterized by plasticity, easy construction, high bonding strength at medium and high temperatures, good abrasion resistance, and resistance to spalling.

Common specifications of plastic refractories

Fireramo provides you with seven different specifications of plastic refractories, CNPR-180, CNPR-170, CNPR-165, CNPR-160, CNPR-155, CNPR-150 and CNPR-145.

Pros and cons of plastic refractories

Advantages of plastic refractory

Good thermal stability

Plastic refractory can be used at a high temperature of 1300~1600℃, and its plasticity index is generally 15%~40%. When used in industrial furnaces, it must be used together with non-metallic or metallic anchors, i.e. anchors and supports must be added in the pounded liner in order to give full play to the advantages of the performance of the refractory plastic material and to improve its service life.

Strong plasticity

Plastic refractory material has excellent abrasion resistance, spalling resistance, and convenient construction.

Dimensional stability

Plastic refractories have small coefficient of thermal expansion, high purity, and are ideal shell materials with high stiffness and high strength.

Excellent dielectric properties

Plastic refractories can remain constant at a wide range of frequencies, temperatures and humidity.

Disadvantages of plastic refractories

Climate intolerant, easily discolored by sunlight.

Poor flowability, difficult to process.

Stress cracking in the presence of organic solvents.

Places where plastic refractories are suitable

Plastic refractories are suitable for use in a variety of furnaces such as heating furnaces, even-heat furnaces, annealing furnaces, sintering furnaces, boilers, etc., where they do not come into direct contact with molten materials. For example, the burner of heating furnace, the discharge opening of cement rotary kiln, the charging opening of vertical kiln, the inner lining of high temperature cyclone separator, the roof and wall lining of rolling mill heating furnace and other parts.

How to buy reliable quality plastic refractories?

Determine the needs: Define the type of refractory materials needed, specifications, the use of the environment, etc., as well as the budget and purchase quantity.
Understand the supplier: choose a supplier with reputation and good word of mouth, you can refer to its qualification, production capacity, product quality and other information.
Confirm product standards: Ask suppliers to provide product standards and quality certification documents to ensure that the purchased materials comply with relevant standards and regulations.
Physical testing: Before purchase, it is best to ask the supplier to provide samples for physical testing to ensure that product quality and performance meet the requirements.
Signing a contract: After confirming the supplier and product quality, sign a formal procurement contract to ensure that the product delivery date, price, quality standards and other matters are clear and reasonable.
Acceptance and warehousing: After receiving the goods, carry out quantity and quality acceptance to ensure that the products meet the purchasing requirements. If there is any quality problem, negotiate with the supplier to solve it in time.
Maintain communication: In the procurement process, maintain good communication with suppliers to ensure timely transmission of information and understanding, to avoid problems due to miscommunication.
Follow the laws and regulations: when purchasing plastic refractory materials, follow the relevant laws and regulations and standards to ensure that the purchased materials meet the requirements of safety, environmental protection and other aspects.

I believe you see here has a clear understanding of the plastic refractory materials, whether it is the characteristics and composition of plastic refractory materials or purchase of plastic refractory materials are the precautions have a clear understanding.
