What are the advantages and disadvantages of phenolic composite duct?

As a new type of air duct, phenolic composite air duct has the advantages of excellent thermal insulation performance, good sealing performance, light weight, fast construction, energy saving and environmental protection. The fly in the ointment is that there is a defect in strength. However, after years of research and development, Wuhan, the flagship brand of the industry, has developed innovative patented products such as double-sided color steel phenolic aldehyde and modified phenolic aldehyde, which completely make up for these shortcomings and make phenolic aldehyde products more widely used.

Advantages:

1 phenolic composite air duct is a kind of air duct made of phenolic resin, which is foamed into phenolic foam rice core material through chemical reaction and compounded with color steel plate. Mainly has the following characteristics: neat appearance, lubrication, three-dimensional sense and comfort. National code for fire protection data of smoke-free, non-toxic and composite high-rise buildings. Good heat insulation performance can greatly reduce the loss caused by heat dissipation. 4. Hard appearance and impact resistance; And is light in weight. Sound insulation is good Small floor space and cost saving. Phenolic composite air duct has excellent thermal insulation and fire prevention performance, and the site construction is simple and easy to operate. Compared with the traditional iron air duct, it has its own thermal insulation function, which greatly saves the cost. Disadvantages: the quality of phenolic boards on the market is uneven, and the bulk density and strength of phenolic boards are difficult to meet the construction requirements. Only large manufacturers have reliable quality phenolic boards, and the domestic popular phenolic boards are Wuhan, Kang Hua, Dingbang Technology, etc. Go home.

Disadvantages:

1. The core material of phenolic composite air duct is powder, which can't be used in clean air conditioning system. 2. The surface skin is aluminum platinum, which can't be used in acid-base air conditioning system. 3. It has low strength and can't be used in high-pressure system.
