In real life, with the progress of society, sealing materials are also constantly developing and growing. Its application fields are also quite extensive, including construction, automotive, high temperature resistant and other industries. In this industry, it is always at the forefront of science and technology. Among them, the application of sealing tape is relatively wide. The actual points are as follows:
1. Turn the roll material on the upper layer of the lap seam that needs to be bonded and sealed to clean the dust and impurities on both sides of the seam or the end of the roll material. Special waterproof material compatible with adhesive sealing tape. It is worth noting that there should be no brush leakage or accumulation when applying waterproof glue. Generally, the amount of brushing is about 0.1kg / m2.
2. After the base layer treatment agent has dried for about 20 minutes and the fingertips are not sticky, you can align one side of the double-sided tape to the edge of the roll or the end of the roll that needs to be lapped. At this time, do not tear off the release paper.
3. After the sealing tape is pasted, you can tear off the separation paper, and turn the rolled material back in time to carry out the adhesive sealing treatment of the lap joint with the coated material on the other side. After the lap seam is bonded, it should be rolled firmly in order by the hand-held pressure roller at the seam to make it adhere firmly.
4. For the waterproof layer of the coil material required by the waterproof grade, a single-sided adhesive tape covered with an aluminum foil polyester composite film or a butyl waterproof sealing tape should be added to the edge of the lap joint for additional enhanced sealing treatment.
5. After the construction is completed, the ends of the roof parapet and the surrounding membrane waterproof layer are closed and the joints are fully treated with single-sided and double-sided waterproof sealants.
