Asphalt roofing paper is a waterproof material used in the construction industry. The original paper has a rough texture, good rarity, and a certain tensile strength. Generally using rags, waste paper, etc. as raw materials, high-level can be used part of animal hair and slag cotton, etc., directly beaten after copying. During processing, the base paper is passed through the molten asphalt and extruded by hot rollers, so that the asphalt will only be saturated, and the excess asphalt is squeezed out. The surface is sprinkled with talc or debris mica, etc., and cooled.
1. excellent heat resistance property, temperature range from -20degree to 60degree
2.excellent isolation, reinforcement, protection
3.high tensile strength
4. impervious to water
6. corrosion resistance
1.Simple waterproofing, temporary waterproofing of temporary buildings, moisture-proofing of buildings, packaging and roofing, single layer underground, multi-layer waterproof protective layer, sealed boxes, moisture-proofing
2.Petroleum asphalt is made of low-softening point petroleum asphalt impregnated with base paper, and then coated with high-softening petroleum asphalt on both sides of the oil paper, and then coated or sprinkled with insulation materials. It has softness number, wolf aging, strong tensile force, long service life, simple construction, Low price characteristics

Applying key points:
1.there are many kind of asphalt roofing felt, when using it, it should be determined by the building's reqirement to decide which specification to use and numbers of layer to cover. When multi-layer covering is applied, the scattered material on the felt surface must be swept away first, and then the asphalt adhesive material of about 1 mm thick is applied. Applying pressure makes the roofing felt stick together firmly.
2.If the rolls of linoleum are stuck together and cannot be unrolled, they can be unrolled by fire. The specific method is as follows: first, build a stove with a slight fire inside, and then bake, peel, and roll the linoleum shelf stove, but you need to spray another layer of the same spreading material as the original (such as the original spreading material is used Sand is ready to use) to avoid sticking after rolling. When baking with low fire, do not burn the coating layer to avoid affecting the quality.
3.Another method is to use the heat of water to melt the linoleum. Petroleum asphalt linoleum is soaked in hot water at 1300 ° C, and coal tar asphalt linoleum is soaked in hot water at 80 ° C. When it can be unfolded, take it out. After drying, sprinkle with sprinkles and roll it.
