Fireproof Cladding for Plastic Pipelines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fireproof cladding materials are not suitable for coating plastic pipelines due to poor mechanical strength, softness, and bendability, which makes them prone to damage during transportation and installation, and they fail to effectively suppress fire spread and smoke generation in building fires.
Innovation Solution
A fireproof cladding material with a two- or three-layer laminated structure formed by needle punch or thermal bond, comprising a fireproof fiber woven blanket and a reinforcement layer, such as glass or carbon fiber cloth, which provides enhanced mechanical strength, softness, and bendability, suitable for coating plastic pipelines, and includes a flame-retardant adhesive tape for easy installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If single-layer flame-resistant fiber cladding material is used, then fireproof function is improved, but mechanical strength and softness deteriorate
Solution Approach 1:
The patent uses composite materials by combining flame-resistant fibers (PAN oxidized fiber, ceramic fiber, or water-soluble alkaline earth fiber) with reinforcing fibers (glass fiber or carbon fiber) in a laminated structure. This composite approach allows the material to simultaneously achieve excellent fireproof properties from the flame-resistant fibers and improved mechanical strength from the reinforcing fibers, resolving the contradiction between fireproof function and mechanical strength.
Solution Approach 2:
The cladding material is segmented into multiple functional layers: an inner layer containing flame-resistant fibers for fireproofing and an outer layer containing reinforcing fibers for mechanical strength. This segmentation allows each layer to perform its specific function optimally while working together as an integrated system, solving the contradiction between fireproof function and mechanical properties.
2Reliability
If aluminum foil lamination is applied to prevent chipping, then product protection is improved, but softness and bendability deteriorate
Solution Approach 1:
The patent changes the material parameters by using flexible reinforcing fibers (glass fiber or carbon fiber) with specific thickness (0.015-0.5mm) and weave patterns that provide protection without excessive rigidity. This allows the cladding to maintain softness and bendability for easy installation while still preventing chipping and damage, resolving the contradiction between product protection and ease of operation.
3Reliability
If multi-layer laminated structure is used, then fireproof performance is improved, but device complexity increases
Solution Approach 1:
The patent segments the cladding into two distinct functional layers: an inner flame-resistant fiber layer for fireproofing and an outer reinforcing fiber layer for mechanical strength. This simple two-layer segmentation achieves improved fireproof performance without excessive structural complexity, making the product practical for building pipeline applications.
