Hot Selling Wooden Roofing Materials Black Asphalt Tar Paper

The production process of asphalt felt paper mainly includes preparing raw materials (such as asphalt, paper, accelerators, stabilizers, etc.), operating equipment (such as asphalt melting pot, coating mixer, rolling mill, etc.), and specific process flow. During the production process, various raw materials are mixed in proportion, stirred evenly by a mixer, and then pressed into rolls or processed into felt paper of the required thickness by a rolling mill. Subsequently, the oil felt paper is subjected to heating, embossing, and other treatments to increase its anti slip performance and aesthetic appeal. Finally, the processed felt paper is cut and packaged to complete the production process.

There are many types of oil felt paper, which can be divided into petroleum asphalt felt, coal asphalt felt, low-temperature resistant felt, powder faced felt, sand faced felt, colored sand faced felt, mineral wool paper felt, asphalt glass cloth felt, metal foil felt, hot-melt felt, self-adhesive felt, flame retardant felt, etc. according to the type of asphalt and spreading fabric, tire base material, functional characteristics, etc. Among them, petroleum asphalt felt can be divided into three specifications according to their grades: 200, 350, and 500. Each specification of felt has its specific application scenarios and performance characteristics.

Construction precautions

Grassroots treatment: Before construction, the base should be thoroughly cleaned and treated to ensure that it is flat, clean, free of oil stains and loose materials.

Laying technique: When laying asphalt glass cloth felt, attention should be paid to the overlap width and overlap method between the rolls to ensure a tight bond between the rolls and the integrity of the waterproof layer.

Temperature control: During the construction process, the temperature and viscosity of the asphalt should be strictly controlled to ensure that the asphalt can be evenly coated on the fiberglass fabric and form a good bonding effect.

Post maintenance: After construction is completed, necessary maintenance and protection should be carried out on the waterproof layer to avoid damage or destruction.

Asphalt glass cloth and felt are widely used in waterproofing projects in fields such as construction, transportation, and water conservancy. For example, in waterproofing treatment of roofs, basements, tunnels, bridges, and other areas, asphalt glass cloth and felt play an important role. In addition, it can also be used to make waterproof materials such as waterproof rolls and waterproof coatings. In the production process, glass fiber fabric is first prepared, and then asphalt is uniformly coated on the glass fiber fabric through impregnation process. After a series of treatments such as heating, rolling, etc., asphalt is tightly bonded with glass fibers to form a roll with a certain thickness and strength.
