The protective effect of flame-retardant felt

The flame-retardant needle non-woven felt literally means that it can prevent combustible materials from burning. This kind of flame-retardant felt is mainly used in public entertainment places, and its main function is to do fire protection. If there is a fire, you can cover the fire with flame-retardant needle-punched flame-retardant felt so that the fire will not spread.　　

Flame-retardant needle-punched flame-retardant felt has a good flame-retardant effect. It also has a certain protective effect when used, and also has a certain decorative effect, because it can be made into many colors, which is no different from ordinary decorations.

Needle-punched flame-retardant felt will add a certain amount of flame-retardant material during production to make it have a flame-retardant effect during use. It can also be customized into different shapes for better use.

Flame-retardant felt is mainly used in engineering winter applications, and is made of double-layer flame-retardant felt composite non-woven fabric. In addition to good insulation effects, flame retardancy is also relatively stable. And because of the protection of the non-woven fabric, the reusability of this product is still very strong. Now, in winter construction, winter insulation quilts are generally purchased, especially in civil engineering, such as concrete jumping and frostbite will affect the strength of the concrete and cause the structure to be unsafe. However, these problems do not exist when using this flame-retardant felt quilt, because its thermal conductivity is low and the heat preservation effect is very good. Its raw material is unworn old clothes, so using it in winter is as difficult as putting on a padded jacket on concrete. The insulation blanket can be used for concrete insulation in winter and concrete maintenance in summer. It has good sun protection and can effectively prevent concrete from cracking. Moreover, the repeatability is strong, the comprehensive price is high, and it can be used for several years. It can also be used as thermal insulation felt for cement curing and concrete curing.

One is thermal insulation cotton felt, also known as needle-punched thermal insulation and flame-retardant felt. It is mainly used for concrete maintenance in winter construction, and can also be used to cover some building materials that are afraid of freezing or for foundation pit earthwork. It is made of two layers of black cotton felt with good insulation effect. It has been repeatedly needle-punched by a needle punching machine during the compounding process, which has good reusability and elastic touch. Of course, general engineering now requires insulation materials to be fireproof. This kind of flame-retardant felt is flame-retardant during processing, so the fireproof performance is very stable, and it can be used with confidence.

This is an upgraded product of engineering thermal insulation and flame-retardant felt, which is made by compounding flame-retardant non-woven fabric on the basis of needle-punched felt. Although the heat preservation effect has not been significantly improved, the ability to be reused has been greatly improved, and there is not much difference. It is also more beautiful and generous, and looks more beautiful in workmanship. In fact, its price is still very high, because its reusability is good, so comprehensively, the price of flame-retardant felt is not more expensive than others in the market, and may be cheaper.
