What are the advantages and differences of plus blanket ceramic fiber blanket compared to ordinary blanket? The Plus blanket of Rosewool Insulation Refractory Co.,Ltd(taking zirconium containing ceramic fiber blanket as an example) is a new type of insulation blanket specially designed for power plant customers for steam turbines. It is made from selected hot raw materials such as coke and gemstones, melted at high temperature, blown into fibers, solidified, cut and rolled, and other processes; Compared with traditional aluminum silicate needle punched blankets, Rosewool Insulation Refractory Co.,Ltd PLUS blankets have lower slag ball content, higher tensile strength, better rebound rate, no burrs in cutting, convenient construction, better insulation effect, and longer service life;

Specification and core advantages of plus blanket ceramic fiber blanket:

1. Lower thermal capacity and thermal conductivity compared to similar products;
2. The fiber diameter is uniform, and the slag ball content is lower in products with same density;
3. Stable chemical properties and powder free use;
4. Same density products have higher tensile strength;
5. High flatness, cutting construction without burrs;
6. Good thermal shock resistance and long service life;

The difference between Plus blanket and ordinary ceramic fiber blanket:

1. Temperature resistance performance:
Zirconium containing type: The maximum operating temperature reaches 1350 ℃, with a linear shrinkage rate of only -3% at 1350 ℃, and extremely strong high-temperature stability.
Ordinary type: resistant to temperatures of about 1000 ℃, with a linear shrinkage rate of -4% at 1000 ℃, suitable for conventional high-temperature scenarios.
2. Thermal conductivity:
At 600 ℃, the thermal conductivity is 0.176 W/m · K, indicating excellent thermal insulation performance.
3. Physical performance:
Compressive strength: ≥ 0.3 MPa (ordinary type), some products can reach 500 MPa (high-strength type).
Bending strength: 6 MPa (ordinary type).
Elongation at break: 8% (ordinary type)

Rosewool Insulation Refractory Co.,Ltd‘s ceramic fiber blanket products are widely used in industrial kilns, high-temperature pipelines, and other fields due to their excellent thermal insulation performance, low heat capacity, and good chemical stability. Usually, it indicates that the product is superior to its ordinary standard products in one or more aspects such as fiber length, toughness, tensile strength, or slag ball control. Specific advantages can be consulted online or by calling the consultation hotline. Our professional staff will provide you with one-on-one explanations. Provide professional solutions for your insulation materials;
