    Selection of waterproof membrane from which to start

    Modified asphalt waterproof membrane with elastic body (SBS) modified asphalt waterproofing membrane, plastic body (APP) modified asphalt waterproofing membrane, asphalt composite flexible waterproof membrane.

    (SBS) modified asphalt waterproofing membrane, plastic body (APP) modified asphalt waterproofing membrane is based on polyester tires or fiberglass tires for the fetal base, asphalt composite tire flexible waterproof membrane is based on asphalt, Composite materials for the matrix, the composite tire is used in most of the chemical fiber rags and high alkali fiberglass mesh compound, easy to dip coated, resistant to mold, water resistance, poor durability, so the service life is short, the main For some temporary buildings or fortification level requirements are not high occasions. The standard specifies that any asphalt waterproofing membrane made of modified asphalt, tire foundation and top surface material other than SBS membrane shall not be referred to as "SBS" membrane.

         First, the packaging logo. The above three materials from the exterior point of view, there is not much difference, so the first look at the packaging, logo is standardized. The manufacturer's name, trade mark, product mark, date of manufacture or batch number, production license number, storage and transportation precautions must be indicated on the label. Each coil should be marked, and in strict accordance with the provisions of national standards in the order of marking. At the same time, pay attention to the shelf life of the coil is generally not more than one year.

         Second, look at the fetal base. You can tear the edge of the method by hand to determine whether the fetal base with the mark is consistent, is completely saturated to meet the standards requirements. The tire base must not have a white mark or light-colored spots that are not saturated. Polyester tire hand is very difficult to tear and pull off, asphalt and fetal base affinity, and asphalt composite tire tires are often easy to tear open, tearing can be observed on the situation of the fetal base.
