Professional Installation Guide for Ceramic Fiber Blankets

This guide applies to the standardized installation of ceramic fiber blankets in scenarios such as industrial furnaces, pipeline insulation, and equipment heat insulation, aiming to ensure construction quality and maximize the product's thermal insulation and fire resistance performance.

I. Pre-Construction Preparation

Material Verification

Confirm that the model (standard type / high-purity type / zirconium-containing type), specifications (thickness, width, density) of the ceramic fiber blanket match the construction conditions. Check that the blanket is free from damage, moisture, deformation, or other issues.

Tool Preparation

Prepare specialized cutting knives, stainless steel anchors, high-temperature adhesives, tape measures, scrapers, protective gloves, dust masks, and other tools and protective gear.

Surface Treatment

Clean oil stains, dust, rust, and loose impurities from the construction surface. Ensure the surface is flat, dry, firm, and free from hollowing. For high-temperature equipment, cool it to room temperature in advance.

II. Installation Steps

Precise Cutting

Cut the ceramic fiber blanket according to the dimensions of the construction surface using a specialized cutting knife. Keep the cut edges straight and reserve an expansion allowance of 5–10mm to avoid bulging due to tight splicing under high temperatures.

Selection of Fixation Methods

Anchor Fixation (Applicable to furnace linings and large equipment):

Drill holes in the base at intervals of 200–300mm and install stainless steel anchors to ensure they are firm and not loose.

Press the ceramic fiber blanket tightly against the base, covering the anchors, and secure the blanket with pressure plates to prevent detachment.

For multi-layer installation, stagger the seams of upper and lower layers by at least 100mm, and avoid continuous seams.

Adhesive Fixation (Applicable to pipelines and small equipment):

Evenly apply high-temperature adhesive to the base, with a thickness of 2–3mm.

Smoothly place the ceramic fiber blanket onto the adhesive layer, compact it with a scraper, and expel air between the blanket and the base.

For pipeline wrapping, tightly wrap from one end to the other, with an overlap width of at least 50mm.

Seam Treatment

Fill the seams between adjacent blankets thoroughly with high-temperature adhesive and seal the surface with ceramic fiber tape to ensure no gaps and prevent heat leakage.

Surface Protection (Optional)

For areas prone to mechanical impact, install stainless steel mesh or metal guards to extend the service life of the ceramic fiber blanket.

III. Construction Precautions

Construction Environment

Avoid construction in rainy or high-humidity conditions. The construction temperature should be controlled between 5–35°C to prevent poor adhesive curing.

Safety Protection

Construction personnel must wear dust masks and protective gloves to avoid inhaling fiber dust or direct skin contact that may cause discomfort. Clean up dust promptly after construction and maintain ventilation in the work area.

Curing Requirements

After installation, allow natural curing for at least 24 hours before use. For high-temperature equipment, the initial temperature increase should be gradual to avoid sudden temperature spikes that may cause blanket cracking.

Prohibited Actions

Do not apply non-high-temperature coatings on the surface of ceramic fiber blankets. Avoid scratching the blanket with sharp objects. Do not install damp ceramic fiber blankets directly.

IV. Quality Acceptance Standards

The blanket is laid flat, free from wrinkles, hollowing, or edge warping, with tight and gap-free seams.

Anchors are evenly spaced, firmly fixed, and free from loosening or detachment.

The overall insulation layer thickness meets design requirements, with a deviation not exceeding ±5mm.

FAQ

Q1: What is the long-term operating temperature range for ceramic fiber blankets?

A1: The temperature resistance varies by model. The standard type has a long-term operating temperature of ≤1050°C, the high-purity type ≤1100°C, and the zirconium-containing type up to 1650°C. The appropriate model can be selected based on the operating conditions.

Q2: Do ceramic fiber blankets contain asbestos? Are they environmentally friendly and safe?

A2: The product is made from high-purity aluminum silicate raw materials and does not contain any asbestos components. It is free from harmful volatile substances, complies with domestic and international environmental and safety standards, and poses no health risks during installation and use.

Q3: Can ceramic fiber blankets be customized in size?

A3: Yes, customization is supported. The standard widths are 610mm and 1220mm, with thicknesses ranging from 20mm to 100mm. Products can be cut to different lengths and densities based on customer requirements to meet personalized construction needs.

Q4: What are the installation methods for ceramic fiber blankets?

A4: There are two main methods. For large industrial furnaces and similar scenarios, stainless steel anchors are used for fixation. For pipelines and small equipment, high-temperature adhesives can be applied for laying or wrapping. For multi-layer installations, seams must be staggered.

Q5: Can ceramic fiber blankets still be used if they get damp?

A5: If dampened for a short period, they can be thoroughly dried at room temperature and used without affecting performance. However, if long-term soaking has caused structural looseness, replacement is recommended to avoid compromising thermal insulation effectiveness.

Q6: Can ceramic fiber blankets be used for fire barrier wall filling?

A6: Yes, the product offers excellent fire resistance, thermal insulation, and sound absorption properties. It is an ideal filling material for fire barrier walls and fire doors in high-rise buildings and industrial plants, effectively preventing the spread of fire.
